Description

Technical Field

[0001] The utility model relates to the field of air separation, in particular to an air cooling tower. Background Art

[0002] The pre-cooling system is an indispensable part of the air separation system. The air temperature after filtration and compression is about 100 degrees, and it must be cooled by a pre-cooling system (usually including an air cooling tower and a water cooling tower). The air cooling tower is a necessary part of the pre-cooling system. The compressed air after cooling through the air cooling tower can enter the downstream purification system and finally undergo distillation separation.

[0003] In the downstream purification system, the air usually needs to be dried before the necessary purification process can be carried out. The existing air-cooling towers for cooling compressed air all use a filler spray structure to cool the compressed air. Although some air-cooling towers are equipped with gas-liquid separation devices, the separation efficiency is too low, resulting in a large amount of free water in the gas after gas-liquid separation. This brings great working pressure to the downstream drying section, resulting in a shortened life and regeneration cycle of the molecular sieve used to dry the gas in the drying section. This not only affects the production efficiency but also usually requires a lot of energy during the regeneration process, which also causes energy waste and affects production.

[0004] Therefore, an air cooling tower is used to solve the above problems. Summary of the invention

DETAILED DESCRIPTION

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the utility model in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0026] In the downstream purification system, the air usually needs to be dried before the necessary purification process can be carried out. The existing air-cooling towers for cooling compressed air all use a filler spray structure to cool the compressed air. Although some air-cooling towers are equipped with gas-liquid separation devices, the separation efficiency is too low, resulting in a large amount of free water in the gas after gas-liquid separation. This brings great working pressure to the downstream drying section, resulting in a shortened life and regeneration cycle of the molecular sieve used to dry the gas in the drying section. This not only affects the production efficiency but also usually requires a lot of energy during the regeneration process, which also causes energy waste and affects production.

[0027] The cooled gas contains dust, which will pollute the air if discharged directly into the atmosphere, and requires a filter to filter it.

[0028] The utility model provides Figures 1 to 5 An air-cooling tower shown includes a tower body 1, a side wall of the tower body 1 is provided with an air inlet 5, a conveying mechanism for conveying gas is provided above the air inlet 5, and the conveying mechanism is located inside the tower body 1. A sieve plate 10 for increasing the spraying area is provided inside the tower body 1, and a filtering mechanism 12 is provided at the top of the inner part of the tower body 1.

[0029] When in use, the air inlet 5 transports gas to the interior of the tower body 1, and the gas drives the conveying mechanism to blow the gas upward. The gas is diffused by blowing and merges with the cooling water sprayed from the water inlet pipe 7 to cool the gas. The sieve plate 10 inside the tower body 1 diffuses the cooling water to increase the area of ​​cooling water spraying. After the gas merges with the cooling water and cools down, the gas rises and passes through the filtering mechanism 12 to be discharged from the interior of the tower body 1. The filtering mechanism 12 filters the gas to ensure that the discharged gas does not pollute the atmosphere.

[0030] A water inlet pipe 7 is provided between the sieve plate 10 and the filtering mechanism 12 , and a water spray head 701 is provided at the water outlet end of the water inlet pipe 7 .

[0031] A partition column 11 is disposed at the top of the sieve plate 10 .

[0032] When in use, the water source sprayed from the water spray head 701 flows to the sieve plate 10 to cool the gas. The water source sprayed from the water spray head 701 flows to the dividing column 11. The top of the dividing column 11 breaks up the cooling water. The broken up water source flows to the sieve plate 10 and then flows to the conveying mechanism through the sieve holes of the sieve plate 10.

[0033] The dividing column 11 is conical, and the top cylindrical surface of the dividing column 11 breaks up the cooling water, and the broken up cooling water flows to the cylindrical surface of the dividing column 11, and then flows to the sieve plate 10. The dividing column 11 is provided to break up the cooling water, and the broken up cooling water flows to the cylindrical surface to avoid diffusing to the inner side wall of the tower body 1.

[0034] After the cooling water directly drips onto the end surface of the sieve plate 10, the water source diffuses back to the surroundings, diffuses onto the inner wall and side wall of the tower body 1, and then flows to the end surface of the sieve plate 10 and accumulates together again.

[0035] Therefore, the partition column 11 prevents the accumulation of the dispersed cooling water. The cooling water drips on the partition column 11 and diffuses to the cylindrical surface of the adjacent partition column 11, reducing the amount of cooling water scattered on the inner wall and side wall of the tower body 1, thereby achieving the purpose of cooling water diffusion.

[0036] The conveying mechanism is arranged below the sieve plate 10 , and comprises a support frame 8 arranged inside the tower body 1 , and a fan 9 is arranged at the top of the support frame 8 .

[0037] When in use, the gas flows into the interior of the tower body 1 through the air inlet 5, and the gas rises, driving the fan 9 to rotate. The rotating fan 9 drives the gas to rise rapidly, thereby achieving the purpose of conveying the gas.

[0038] The filtering mechanism 12 includes a support plate 1201 provided with two side walls inside the tower body 1, a fixed plate 1202 is provided at the top of the support plate 1201, a movable plate 1203 is provided on one side of the fixed plate 1202 close to the inner wall of the tower body 1, and a movable part 1205 is provided between the movable plate 1203 and the fixed plate 1202.

[0039] A filter plate 1204 is disposed on one side of the movable plate 1203 , and the filter plate 1204 is disposed on the top of the support plate 1201 .

[0040] The filter plate 1204 is concave, and the protrusions on both sides of the filter plate 1204 are clamped between the movable plate 1203 and the side wall of the tower body 1.

[0041] When in use, the filter plate 1204 slides into the interior of the tower body 1, and the two sides of the filter plate 1204 compress the movable plate 1203, and the movable plate 1203 compresses the movable part 1205, so that the movable plate 1203 approaches the fixed plate 1202, and the distance between the movable plate 1203 and the side wall of the tower body 1 is increased, so that the filter plate 1204 has enough space to slide into the interior of the tower body 1, and the filter plate 1204 is slid and placed on the top of the support plate 1201, and the support plate 1201 supports the filter plate 1204.

[0042] A clamping column 1207 is disposed on one side of the movable plate 1203 close to the filter plate 1204 , and a clamping hole 1209 is provided on the inner side of the filter plate 1204 , and the clamping column 1207 is clamped with the clamping hole 1209 .

[0043] When in use, after the filter plate 1204 slides into the interior of the tower body 1 , the movable member 1205 drives the movable plate 1203 to approach the filter plate 1204 , so that the clamping column 1207 of the movable plate 1203 is clamped with the clamping hole 1209 of the filter plate 1204 .

[0044] The movable member 1205 drives the movable plate 1203 to support the filter plate 1204 on both sides, and at the same time, the clamping column 1207 is clamped with the clamping hole 1209 to prevent the filter plate 1204 from being separated from the support plate 1201 during use.

[0045] The cross-section of the clamping column 1207 is an arc shape, and the bottom end of the clamping hole 1209 is an arc surface. The two are clamped together and are easy to disassemble. When disassembly is required, the filter plate 1204 is pulled, and the arc surface edge of the clamping hole 1209 of the filter plate 1204 compresses the arc surface of the clamping column 1207. The clamping column 1207 pushes the movable plate 1203 to move, and the movable plate 1203 moves toward the fixed plate 1202. The distance between the movable plate 1203 and the side wall of the tower body 1 increases, and then the filter plate 1204 is pulled out to facilitate replacement or repair of the filter plate 1204.

[0046] The front end of the movable plate 1203 is provided with an inclined angle 1206 on one side close to the filter plate 1204, and the rear end of the filter plate 1204 is provided with an inclined angle 1208 on one side close to the movable plate 1203. The inclined angle 1206 and the inclined angle 1208 are inserted and connected in a staggered manner.

[0047] When in use, the inclination angle 1206 of the movable plate 1203 matches the inclination angle 1208 of the filter plate 1204, and no manual intervention is required. The edge of the inclination angle 1208 of the filter plate 1204 compresses the edge of the inclination angle 1206 of the movable plate 1203, and the movable plate 1203 moves in the same way as the movable plate 1203 is compressed by the clamping column 1207.

[0048] The movable member 1205 is a spring.

[0049] A front baffle plate 2 is provided on the front side of the tower body 1, a movable block 3 is provided above the front side of the front baffle plate 2, and the movable block 3 is coaxial with the filtering mechanism 12. A drainage hole 6 is provided at the bottom end of the tower body 1, and an exhaust hole 4 is provided at the top end of the tower body 1.

[0050] When in use, the movable block 3 is snap-connected with the front baffle 2. When in use, by opening the snap-connecting mechanism, the movable block 3 moves on the front baffle 2, pushing the movable block 3 to enter the interior of the tower body 1, pulling the filter plate 1204, the filter plate 1204 passes through the front baffle 2 and is pulled out from the movable block 3, the filter plate 1204 is replaced, the drain hole 6 is used to discharge the coolant inside the tower body 1, and the exhaust hole 4 discharges the cooled and filtered gas.
