Description

Technical Field

[0001] The utility model relates to the technical field of pump station deodorization equipment, and more specifically, to a highly efficient biological deodorization tower. Background Art

[0002] Biological deodorization equipment can be said to be a more ideal deodorization equipment for domestic sewage stations. Biological deodorization equipment uses efficient deodorizing bacteria and reasonable deodorizing equipment structure. The odor passes through the moist, porous and active microbial biological filter layer, and is adsorbed, absorbed and degraded by the microbial cells attached to the filler, so that the macromolecules or complex organic matter in the odor undergo alienation and eventually decompose and oxidize into inorganic substances such as water and carbon dioxide.

[0003] The existing biological deodorization tower discharges the waste gas directly into the deodorization tower and contacts the waste gas with the fillers arranged inside the tower, so that the hydrogen sulfide and ammonia in the waste gas are absorbed and reacted. This method prevents the waste gas from passing through the filler layer evenly, and the reaction efficiency is low. Therefore, it is difficult for the waste gas to meet the emission standards after it is discharged. The waste gas needs to be circulated for multiple times to meet the emission standards.

[0004] Therefore, a new technical solution is urgently needed to solve the above technical problems. Utility Model Content

[0007] By adopting the above technical solution, when the waste gas enters the deodorization tower body, it passes through the biological fillers in the first treatment chamber, the second treatment chamber and the third treatment chamber in sequence along the S-shaped path to absorb the hydrogen sulfide and ammonia in the waste gas, thereby effectively treating the waste gas.

It should be noted that the words "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to directions in the drawings, and the words "bottom" and "top", "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0020] As shown in the figure, a high-efficiency biological deodorization tower includes a deodorization tower body 1, wherein two vertically arranged first partitions 2 and second partitions 3 are arranged inside the deodorization tower body 1, and the interior of the deodorization tower body 1 is divided into a first treatment chamber, a second treatment chamber and a third treatment chamber by the first partition 2 and the second partition 3, and the top of the first partition 2 and the bottom of the second partition 3 are both provided with through grooves for the flow of waste gas, and the first treatment chamber, the second treatment chamber and the third treatment chamber are respectively provided with horizontally arranged first support nets 4, second support nets 5 and third support nets 6, and the first support nets 4, the second support nets 5 and the third support nets 6 are all provided with biological fillers 7.

[0021] When the waste gas enters the deodorizing tower body 1, it passes through the biological fillers 7 in the first treatment chamber, the second treatment chamber and the third treatment chamber in sequence along an S-shaped path to absorb the hydrogen sulfide and ammonia in the waste gas, thereby effectively treating the waste gas.

[0022] An air inlet pipe 8 connected to the first treatment chamber is provided at the bottom of one side of the deodorizing tower body 1, and a honeycomb plate 9 is provided in the first treatment chamber between the first support net 4 and the air inlet pipe 8. A first water distributor 10 is provided above the biological filler 7 in the deodorizing tower body 1, a one-way valve 11 is provided on the air inlet pipe 8, and a first liquid discharge pipe 12 connected to the first treatment chamber is provided at the bottom of one side of the deodorizing tower body, and a first solenoid valve 13 is provided on the first liquid discharge pipe 12.

[0023] Water is distributed to the first treatment chamber through the first water distributor 10. A first liquid level sensor (not shown in the figure) is provided in the first treatment chamber to ensure that the liquid level inside is higher than the height of the air intake pipe 8 and lower than the height of the honeycomb plate 9. When the exhaust gas enters the bottom of the first treatment chamber from the air intake pipe 8, it first contacts with water, and part of the gas in the exhaust gas is absorbed by the water to improve the treatment effect of the exhaust gas. When the exhaust gas rises, the exhaust gas is further dispersed by the honeycomb plate 9, and is evenly contacted with the biological filler 7 through the first support net 4 to ensure the treatment efficiency of the biological filler 7 for the exhaust gas. After a certain period of time, the first solenoid valve 13 is opened to recycle the waste water inside.

[0024] The third treatment chamber is located above the biological filler 7 and is provided with a second water distributor 14. A second liquid level sensor (not shown in the figure) is provided at the bottom of the second treatment chamber. A second drainage pipe 15 connected to the second treatment chamber and the second treatment chamber is provided at the bottom of the deodorizing tower body 1. A second electromagnetic valve 16 is provided on the second drainage pipe 15. The second water distributor 14 replenishes water at the bottom of the second treatment chamber and the third treatment chamber, and its liquid level is lower than the height of the second support net 5 and the third support net 6. When the waste gas moves downward from the second treatment chamber and passes through the second support net 5, it contacts the water again, and part of the gas in the waste gas is absorbed again by the water. After a certain period of time, the second electromagnetic valve 16 is opened to recycle the waste water inside.

[0025] An exhaust pipe 17 connected to the third treatment chamber is provided on one side wall of the deodorizing tower body 1. The exhaust pipe 17 is located above the second water distributor 14.

A third solenoid valve 19 is also provided on the exhaust pipe 17. A demister 20 is provided in the third treatment chamber between the exhaust pipe 17 and the second water distributor 14. When the exhaust gas moves upward through the third treatment chamber, the moisture in the exhaust gas is absorbed by the demister 20.

[0026] A fourth solenoid valve 21 is provided on the circulation pipe 18, and an exhaust gas detection device (not shown in the figure) is also provided above the demister 20 in the third processing chamber. When the exhaust gas detection device detects that the treated exhaust gas does not meet the emission standards, the third solenoid valve 19 is closed and the fourth solenoid valve 21 is opened, so that the exhaust gas passes through the circulation pipe 18 and enters the deodorizing tower body 1 again for treatment. When the exhaust gas detection device detects that the treated exhaust gas meets the emission standards, the third solenoid valve 19 is opened and the fourth solenoid valve 21 is closed to discharge the exhaust gas.
