In the chlor-alkali production industry, a diversion groove is basically used at present, the device is also one of the main devices used in the brine production position, the main function of the device is to change the direction of a fluid by utilizing the fall of an inlet and an outlet pipeline to form a turbulent flow direction, and then some refining agents are added into the device to carry out mixing reaction through natural turbulence.

The existing diversion grooves are different in style, and the simplest rectangular fluid groove is provided with a half-surface baffle plate directly perpendicular to the fluid direction (as shown in figure 1a) and is also provided with a half-surface baffle plate arranged in a forward flow direction or a reverse flow direction with a certain angle to form a turbulent fluid flow direction (as shown in figure 1 b).

Although the two diversion grooves have simple structure, the defects are more. Firstly, laminar flow can be formed when the fall of the inlet and the outlet of the fluid is too small, and even if a refining agent is added, effective reaction can not be obtained because ions to be removed cannot be in full contact with the refining agent, so that the production cost is increased, and indexes cannot be effectively controlled; secondly, no matter which kind of baffling groove's use, the enterprise of production is thrown to the discontinuity all can have the floating salt to get into in the baffling groove, and especially when just beginning to throw the material, a large amount of long-pending salt appears easily in the baffling board back (the baffle face of the fluid flow direction of being the opposite), probably not all dissolve because the flow is big, baffling groove is short and directly get into next equipment even, leads to the concentration index to appear fluctuating by a wide margin.

Detailed Description

The present invention will be described in further detail below with reference to specific embodiments and with reference to the attached drawings.

The baffling groove provided by the invention is mainly used in combination with a salt melting barrel, raw salt (industrial-grade potassium chloride or sodium chloride) is sent into the salt melting barrel through mechanical equipment or transmission equipment, the salt melting barrel and the raw salt are reversely contacted and dissolved, but because the poured raw salt occupies part of the volume, salt water overflows from the salt melting barrel and enters the baffling groove, and the salt water entering the baffling groove carries the undissolved raw salt, so that a large amount of salt accumulation easily occurs on the back surface of a baffling plate (the surface of the baffle plate opposite to the flow direction of a fluid) in the conventional baffling groove, even the salt accumulation is not completely dissolved due to large flow and short baffling groove and directly enters next equipment, and the concentration index is greatly fluctuated.

As shown in fig. 1 to 4, the baffle device provided by the present invention comprises a baffle body 1 in a long cylinder shape or a long box shape, a muddy brine inlet 2 and a muddy brine outlet 3 which are arranged on the baffle body 1, wherein the muddy brine inlet 2 is used for sending the brine with the original salt into the baffle body 1, and the muddy brine outlet is used for sending the brine after the full reaction out of the baffle body 1. Reaction zone 1.1 and monitoring area 1.2 are had in baffling groove body 1, reaction zone 1.1 is located baffling groove body 1's entrance point, reaction zone 1.1 is arranged in making the muddy brine that has original salt secretly, the continuous mixed reaction of impurity ion that needs to get rid of in refining agents such as alkali (NaOH or KOH) and barium chloride that add and the muddy brine, and monitoring area 1.2 is located baffling groove body 1's exit end, monitoring area 1.2 is the salt water after the original salt has fully dissolved, monitoring area 1.2 salt water concentration is stable, the concentration of convenient salt water detects.

Reaction zone 1.1 still installs the hybrid sheet 5 of crisscross arrangement, extend the end from hybrid sheet 5 and incline to muddy brine import 2, hybrid sheet 5 bottom has tailors breach 6, multiunit guide plate 4 is all installed with monitoring area 1.2 in reaction zone 1.1, multiunit guide plate 4 in reaction zone 1.1 all is located between two adjacent hybrid sheets 5, and every group guide plate 4 all includes two guide plates 4 that are crisscross arrangement, 3 slopes are all followed to the extension end of every guide plate 4, hybrid sheet 5 and guide plate 4 are after the installation, hybrid sheet 5 and guide plate 4's below can be through muddy brine through tailorring breach 6 to take place to mix with the muddy brine of hybrid sheet 5 and guide plate 4 opposite side.

From the muddy brine inlet 2, an area A is arranged between the inner side of the mixing plate 5 and the inner wall of the baffle tank body 1, an area B is arranged between the outer side of the extending end of the mixing plate 5 and the adjacent guide plate 4, an area C is arranged between the mixing plate 5 and the guide plate 4 on the same side, and an area D is arranged between the guide plate 4 of the same group and the next mixing plate 5. When muddy brine containing undissolved original salt enters the baffle tank body 1 through the muddy brine inlet 2, most of the muddy brine enters the area A to form vortex, part of the muddy brine in the area A bypasses the extending end of the mixing plate 5 and enters the area C from the area B, the other part of the muddy brine in the area A directly enters the area C through the cutting notch 6 at the bottom of the mixing plate 5, one part of the muddy brine entering the area B automatically enters the area C along the guide plate 4, the other part of the muddy brine entering the area B enters the area D through the cutting notch 6, and the two parts of the muddy brine are repeatedly stirred in the areas of the reaction area 1.1 except the area A and the area B, so that the muddy brine can be mixed up and down and in a cross mode to the maximum extent, the dead angle can be prevented from being formed at the lower end of the area A, the dead angle can be prevented from being formed at the back sides of the guide plates 4 at the area B and the area C, avoid "dead angle" position a large amount of long-pending salt to appear, make salt water flow the in-process and the abundant contact of suspended crude salt mix and dissolve, through repetitious, make the crude salt of suspension totally dissolve to when making salt water enter into monitoring area 1.2, the floating salt has dissolved completely, makes monitoring area 1.2 salt concentration stable, thereby makes salt water concentration detection stable.

In the invention, the refining agent such as strong alkali (NaOH or KOH) and barium chloride and the like which needs to be added can be directly added from the muddy brine inlet 2, and the refining agent can also be added from the C area, so that the refining agent and the muddy brine react fiercely in the C area, and even if the refining agent and the muddy brine do not react completely in the C area, the refining agent and the muddy brine can also enter the next A area, B area, C area and D area to be mixed up and down, and the full reaction can also be ensured.

In some embodiments, the inclination angle of the guide plate 4 located in the reaction zone 1.1 is randomly arranged, so that when the turbid brine is guided by the guide plate 4 in the reaction zone 1.1, the flow path of the turbid brine does not have any rule, the stirring effect of the turbid brine in the flow process is better, the refining agent and the turbid brine can fully react, and the original salt in the brine can be fully dissolved; simultaneously, the inclination angle that is located monitoring area 1.2's guide plate 4 is the same, makes the muddy saltwater after reaction zone 1.1 more steady in the flow of monitoring area 1.2, makes monitoring area 1.2's saltwater concentration more stable, makes the saltwater concentration detection more stable.

In some embodiments, the angle of inclination of the baffle 4 in the reaction zone 1.1 is 15 ° to 75 °, and the specific angle of inclination of the baffle 4 can be adjusted according to the shape and size of the baffle body 1 and the preparation requirement of the brine.

In some embodiments, the inclination angles of the two guide plates 4 arranged in a staggered manner in the reaction zone 1.1 are 45 ° and 75 °, so that dead corners between the back of each guide plate 4 and the inner wall of the baffle tank body 1 due to excessive inclination of each guide plate 4 are avoided while the guide plates 4 are kept inclined, and the turbid brine flows more sufficiently in the reaction zone 1.1.

In some embodiments, the two adjacent guide plates 4 located on the same side of the reaction area 1.1 have different inclination angles, so that the turbid brine is more turbulent in the flowing process, the turbid brine can fully react in the reaction area 1.1, and the dissolving effect of the original salt in the reaction area 1.1 is better.

In some embodiments, the angle of inclination of the deflector 4 of the monitoring zone 1.2 is 45 ° to make the flow of brine more smooth and the measured brine concentration more stable.

In some embodiments, the inclination angle of the mixing plate 5 is 15 ° to 75 °, preferably, the inclination angle of the mixing plate 5 is 45 °, and the specific inclination angle of the mixing plate 5 can be adjusted according to the content of the original salt in the turbid brine, the size and shape of the baffle groove, etc., so as to ensure that the turbid brine can be sufficiently stirred when passing through the reaction zone 1.1, thereby not only sufficiently reacting the refining agent with the turbid brine, but also sufficiently dissolving the original salt in the brine.

In some embodiments, the welding edges 7 of the mixing plate 5 and the flow guide plate 4 are two adjacent right-angle edges of the mixing plate 5, so that the mixing plate 5 and the two right-angle edges of the baffle tank body 1 and the flow guide plate 4 and the two right-angle edges of the baffle tank body 1 form a triangular structure, the mixing plate 5 and the flow guide plate 4 are more firmly installed, and the mixing plate 5 and the flow guide plate 4 are prevented from falling off due to the impact of muddy brine; simultaneously, cut out breach 6 and be located between two welding limit 7 of hybrid board 5 or guide plate 4, the right angle department that makes baffle groove body 1 has a through-hole, can not only avoid the right angle limit of baffle groove body 1 to produce "dead angle", and make muddy salt water when cutting out breach 6, the rivers of hybrid board 5 or guide plate 4 welding limit 7 draw in to cutting out breach 6 and pass through, the rivers that make the welding limit 7 of hybrid board 5 or guide plate 4 receive a great traction force, effectively avoid the former salt deposit in muddy salt water at the welding limit 7 of hybrid board 5, make dissolving of former salt more thorough.

Here, one or more through holes can be formed at the bottom of the mixing plate 5 or the flow guide plate 4 to replace the cutting gap 6, on one hand, the muddy brine can disperse the water pressure of the muddy brine when passing through the plurality of through holes, so that the water flow at the welding edge 7 of the mixing plate 5 or the flow guide plate 4 is subjected to smaller traction force, a part of original salt in the muddy brine can be deposited on the welding edge 7 of the mixing plate 5 or the flow guide plate 4 under the action of gravity, if the cutting gap 6 is replaced by one through hole, the muddy brine at the bottom of the baffle tank body 1 cannot effectively pass through the through hole if the through hole is higher than the bottom of the baffle tank body 1, if the bottom of the through hole is flush with the baffle tank body 1, but the through hole is positioned in the middle of the lower edge of the mixing plate 5 or the flow guide plate 4, a dead angle can be formed at the right-angled muddy position of the bottom of the baffle tank body 1, and the water flow traction force cannot be applied to the muddy brine at the position, causing the crude salt to settle at the right angle. Therefore, the absolute deposition of the original salt in the baffle groove is guaranteed, the notch 6 can be cut through the matching of the through holes formed in the mixing plate 5 or the guide plate 4, the water pressure of the muddy brine and the influence on the cut notch 6 when the muddy brine passes through the through holes need to be considered when the device is arranged, the water pressure of the muddy brine when the muddy brine passes through the cut notch 6 is guaranteed, and the traction force generated by the muddy brine at the cut notch 6 on the water flow of the welding edge 7 of the mixing plate 5 is guaranteed.

In some embodiments, the flow guide plate 4 and the mixing plate 5 are rectangular, and the width of the mixing plate 5 and the width of the flow guide plate 4 are both smaller than the internal width of the baffle tank body 1, so that after the mixing plate 5 and the flow guide plate 4 are installed, a hollow part is arranged between the side edges of the flow guide plate 4 and the inner wall of the baffle tank body 1, when muddy brine passes through the flow guide plate 4 and the flow guide plate 4, a part of muddy brine can directly pass through the hollow part, and the other part of muddy brine needs to turn over the mixing plate 5 and the flow guide plate 4, so that the two parts of muddy brine are mixed up and down and mixed in a cross manner, salt accumulation at the dead angle position of the flow guide plate 4 and the mixing plate 5 can be effectively avoided, and original salt in the muddy brine can be fully dissolved.

When turbid brine containing undissolved original salt enters the baffle tank body 1 through the turbid brine inlet 2, most of the turbid brine enters the area A to form vortex, a part of the turbid brine enters the area C from the area B by turning over the extending end of the mixing plate 5, and the other part of turbid brine in the area A directly enters the area C through a cutting notch 6 and a hollow-out part at the bottom of the mixing plate 5, so that the two parts of turbid brine are stirred, the turbid brine is mixed up and down and in a cross way to the maximum extent, the lower end of the area A is prevented from forming a dead angle, a large amount of salt accumulation at the dead angle is avoided, the brine is fully contacted, mixed and dissolved with the suspended original salt in the flowing process, and the suspended original salt is completely dissolved after repeated times, therefore, when the saline enters the monitoring area 1.2, the floating salt is completely dissolved, the saline concentration of the monitoring area 1.2 is stable, and the saline concentration detection is stable.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
