Technical Field

The invention belongs to the technical field of water distribution systems of sewage treatment IC reactors, and particularly relates to a three-dimensional flow water distributor for an IC reactor.

Background

In order to achieve a good effect of the existing sewage treatment IC process anaerobic reactor, an efficient water distribution system needs to be installed, so that inlet water is uniformly distributed at the bottom of the anaerobic reaction tank. Most of the existing water distribution is branch water distribution, pulse water distribution and rotational flow water distribution. The branched water distribution is easy to block and is not uniform; the internal flow channel of the cyclone water distributor is mostly non-round and moist, the dead angle is more uneven in mixing, and the water distribution resistance is too large.

Disclosure of Invention

The invention provides a three-dimensional flow water distributor for an anaerobic reactor, which can solve the technical problems of uneven water distribution and large resistance of non-round internal flow channels of the traditional anaerobic reactor.

The technical scheme is as follows:

a three-dimensional flow water distributor for an IC reactor comprises a pseudo-spherical flow guide base, a flow distribution ball, three-dimensional mixed flow guide vanes and a conical shell.

Wherein: the conical shell is of a cavity structure and is located the ternary mixing flow guide blade, the conical shell is provided with a plurality of raw water inlet pipes, the conical top of the cone is provided with a backflow water inlet pipe, and the raw water inlet pipes are uniformly distributed on the same horizontal plane.

Wherein: the flow dividing ball is positioned on the pseudo spherical surface flow guide base and connected with the base, the ternary mixed flow guide blade is positioned on the pseudo spherical surface flow guide base, and the ternary mixed flow guide blade is connected with the pseudo spherical surface flow guide base at the blade root.

By adopting the scheme, raw water is fed by the feed pump, simultaneously enters the three-dimensional flow water distributor through the plurality of raw water inlet pipes and is mixed with the return water passing through the return water inlet pipe for one time. The center of a circle at the outlet end of the raw water inlet pipe points to the center of the flow dividing ball, and raw water is reflected by the flow dividing ball and uniformly dispersed; the flow dividing balls also uniformly disperse the return water. The mixed liquid is uniformly dispersed into the flow channel between the ternary mixed guide vanes through the ternary mixed guide vanes. The flow channel is composed of two adjacent ternary mixed guide vanes and a pseudo spherical surface of the pseudo spherical surface guide base. The pseudo-spherical surface can enable the mixed liquid flowing down vertically to be smoothly redirected to the horizontal flowing direction. And a flow channel between two adjacent ternary mixed guide vanes is a twisted streamline channel, so that the mixed liquid forms rotational flow and is stirred to generate vortex, and secondary mixing is formed. The plurality of the twisted streamline channels are arranged in a fan blade shape by taking the center of the horizontal section of the three-dimensional flow water distributor as the center of a circle, and the radian bending directions of the twisted streamline channels face the same hour hand direction. The mixed liquid flows back through the outlet of the twisted streamline passage in a tangential direction to form a swirling effect.

The invention has the beneficial effects that: raw water and return water can directly enter the three-dimensional flow water distributor to be fully mixed, the loss of water distribution on-way resistance is reduced, water flow from the water outlet is enabled to rotate at a high speed, strains in the IC reactor are uniformly mixed, and the strains are not easy to precipitate.

Detailed Description

Referring to fig. 1-5, the embodiments are as follows:

a three-dimensional flow water distributor for an IC reactor is made of stainless steel. The device comprises a return water inlet pipe 6 which is arranged on a conical shell 4. The raw water inlet pipe 5 is fixed on the conical shell 4, and the circle center of the port of the raw water inlet pipe 5 points to the sphere center of the flow dividing ball 2 and is distributed along the same rotation direction of the sphere center of the flow dividing ball 2. 4-8 raw water inlet pipes can be arranged on the raw water inlet pipe 5. Raw water enters the three-dimensional flow water distributor through the raw water inlet pipe 5 and is mixed with return water passing through the return water inlet pipe 6 at one time. Raw water is reflected by the flow dividing ball 2 and uniformly dispersed; the diverter balls 2 also evenly disperse the return water.

The flow guiding device comprises a pseudo-spherical flow guiding base 1 and a flow dividing ball 2 positioned on the top of the pseudo-spherical flow guiding base 1, wherein the pseudo-spherical flow guiding base 1 and the flow dividing ball 2 are welded and fixed together. The ternary mixed guide vanes 3 are positioned on the surface of the pseudo-spherical guide base 1, and the bottoms of the ternary mixed guide vanes 3 are welded on the pseudo-spherical surface of the pseudo-spherical guide base 1; the ternary mixed guide vanes 3 are uniformly distributed along the circumferential direction on the pseudo-spherical guide base and are distributed along the same circumferential rotation direction.

The number of the ternary mixed guide vanes 3 can be set to be 6-12. The three-element mixed guide vane 3 is installed at a dome-shaped height. The lower outlet end of the dome shape supports and fixes the conical shell 4, the upper part of the dome shape and the conical shell 4 form a cavity, and the mixed liquid is mixed and shunted in the cavity.

The mixed liquid is uniformly dispersed in the flow passage between the ternary mixed guide vanes 3 through the ternary mixed guide vanes 3. The flow channel is composed of two adjacent ternary mixed guide vanes and a pseudo spherical surface of the pseudo spherical surface guide base 1. The pseudo-spherical surface causes the mixed liquid vertically downward to change the flowing direction roundly. And a flow passage between two adjacent ternary mixed guide vanes 3 is a twisted streamline passage, so that the mixed liquid forms rotational flow and is stirred to generate vortex, and secondary mixing is formed. The plurality of the twisted streamline channels are arranged in a fan blade shape by taking the center of the horizontal section of the three-dimensional flow water distributor as the center of a circle, and the radian bending directions of the twisted streamline channels face the same hour hand direction.

During operation, the mixed liquid passes through the twisted streamline channel, so that the on-way resistance loss is reduced, the full mixing is realized, the mixed liquid flows out from the outlet in the tangential direction, and the water flow from the water outlet forms a high-speed rotating eddy effect. The strains in the IC reactor are uniformly mixed and are not easy to precipitate.

Compared with the traditional IC water distribution equipment, the device has the advantages that the structure is more reasonable, the water distribution resistance is smaller and more uniform by adopting the device, a certain sludge stirring effect is realized, the granular sludge is fully contacted with the wastewater, and the sludge utilization rate is improved to the maximum extent; the concentration of inlet water is effectively diluted, and acidification of an anaerobic treatment system caused by excessive high-concentration organic matters is avoided; the water distribution device has the advantages of simple structure, simplicity in operation, convenience in monitoring the flow of each water distribution point and the like.
