2. Installing a condensed water distributor:

firstly welding the spray cavity 3-2 to the center of the upper end enclosure of the tank body 1, then inserting the condensed water inlet pipe 3-3 into a round hole on the upper side surface of the spray cavity 3-2, fixing and sealing by using a welding method, tightly fixing the spray cavity 3-2 and the spray cavity 3-6 by using 8 through holes 3-11 arranged in an array on the upper end surface of the screw sleeve 3-6 and 8 threaded holes arranged in an array on the upper end surface of the spray cavity 3-2 by using screws, and screwing the adjusting cone into the threaded through hole 3-10 in the center of the screw sleeve 3-6 to a proper position from the lower part by using the threaded through hole 3-10 in the center of the screw sleeve 3-6 and the external threads on the straight rod part 3-7 of the adjusting cone. The upper end socket provided with the condensed water distributor 3 is welded above the straight cylinder section of the tank body 1, and the lower end socket provided with the water outlet pipe 10 is welded below the straight cylinder section of the tank body 1.

3. Installing an exhaust treatment device:

firstly, welding corresponding hollow baffle plates 12-8 between an upper surface water through groove 12-11 of a cooling liquid water inlet tank 12-9 and a lower surface water through groove of a cooling liquid water outlet tank 12-10, communicating a middle cavity of the cooling liquid water inlet tank 12-9 with a middle cavity of the cooling liquid water outlet tank 12-10, and welding an upper shell 12-1 on the middle cavity; then welding the lower shell 12-2 below the upper shell 12-1 to form a whole with 12-1 seals; the left side of an upper shell 12-1 is provided with 1 exhaust inlet pipe 12-3, the right side thereof is provided with 1 exhaust outlet pipe 12-4, the left side of a cooling liquid inlet box 12-9 is provided with 1 cooling liquid inlet pipe 12-5, the right side of a cooling liquid outlet box 12-10 is provided with 1 cooling liquid outlet pipe 12-6, and the center position below the lower shell 12-2 is provided with 1 condensate water outlet pipe 12-7. The exhaust inlet pipe 12-3 is connected with an exhaust pipe 11 on the upper end enclosure.

The working process of the vertical high-temperature condensed water deaerating device is as follows:

1. spreading condensed water:

condensed water enters a cavity 3-4 in the middle of the distributing and sprinkling device through a condensed water inlet pipe 3-3, a threaded through hole 3-10 in the center of a threaded sleeve 3-6 and an external thread on a straight rod part 3-7 of the adjusting cone are both fine threads, the thread pitches of the threaded through hole and the external thread are consistent with the thread shapes, the threaded through hole and the external thread have sealing effects when the threaded through hole and the external thread are screwed, and the condensed water is sprayed out from a gap formed by a bell mouth 3-5 below the spraying cavity 3-2 and a cone 3-8 below the adjusting cone to form a water film. The hexagonal head 3-9 of the straight rod part 3-7 of the adjusting cone is rotated by a manual or electric wrench, the relative distance between the bell mouth 3-5 and the cone 3-8 can be adjusted, the thickness of the water film of the condensed water is adjusted, the problem that the thickness of the water film of the condensed water is not adjustable is effectively solved, the capability of heating the condensed water to the saturation temperature is greatly improved, and the escape rate of oxygen in the condensed water is effectively improved.

2. Thermal deoxygenation:

steam enters from the bearing steam pipeline 9-2, then enters into the submerged steam tray 9-4 through the support steam pipeline 9-3 and 4 first air holes 9-5 arranged in an array on the support steam pipeline, and is sprayed into water liquid through second air nozzles 9-8 arranged in an array on the upper surface, the circumferential side surface and the bottom surface of the submerged steam tray 9-4, the steam is fully contacted with condensed water, so that the condensed water is quickly heated to the saturation temperature, and oxygen in the water is enabled to escape; steam enters the rotary steam arm through the support steam pipeline 9-3 and 8 second air holes 9-11 arrayed on the upper part of the support steam pipeline, the steam is then sprayed out from the first air nozzles 9-7 arrayed on the two steam arms 9-6, and the horizontal angle difference of the air spraying directions of the air nozzles on the two steam arms 9-6 is 180 degrees, so that the rotary steam arm rotates by itself, the rotary steam arm 9-6 uniformly sprays the steam on the surface of the liquid surface, the water film sprayed above the rotary steam arm is convenient to heat, the escape of oxygen in the water film is also facilitated, the rotary steam arm 9-6 plays a role of disturbing the water surface at the same time, the surface tension of the water surface is effectively reduced, and the oxygen under the water is convenient to diffuse to the water surface. The steam spraying device is novel in design, reasonable and reliable in function and low in manufacturing cost, effectively solves the problems that a steam pipeline in the deaerating device is too numerous and complex and is not beneficial to effective control of the production process, and effectively reduces the difficulty and cost of manufacturing the device.

3. And (3) exhaust treatment:

mixed exhaust enters the upper shell 12-1 from the exhaust inlet pipe 12-3 and collides with the hollow baffle plates 12-8 arranged in a folding way, the mixed exhaust is repeatedly baffled and repeatedly collided, and in a working condition, the cooling liquid enters the cooling liquid inlet box 12-9 from the cooling liquid inlet pipe 12-5 and then enters the hollow baffle plate 12-8, then enters a cooling liquid outlet tank 12-10 to be discharged through a cooling liquid outlet pipe 12-6, the hollow baffle plate 12-8 also has the condensation separation effect on the mixed exhaust gas, after the separated condensed water is collected from the upper surface of a cooling liquid inlet tank 12-9 with an included angle of 3 degrees, flows into the lower shell 12-2 from the gap between the end and the side of the upper shell 12-1, then the condensed water is discharged into the next process equipment from the condensed water outlet pipe 12-7, and other gases such as oxygen and the like are discharged from the exhaust outlet pipe 12-4. The exhaust treatment device has novel design and reasonable structure, and can effectively solve the problem of poor treatment effect of the existing exhaust treatment device.
