Description

Technical Field

[0001] The invention relates to the technical field of industrial odor treatment, in particular to a multi-stage industrial odor collection and treatment device. Background Art

[0002] Industrial odor is an important factor causing environmental pollution, and the impact of odorous gases on the environment and human body is particularly serious. As a typical environmental hazard, it has been recognized by countries around the world. Foreign countries have also started to control odor pollution earlier. In many industrial fields in Japan, Europe and the United States, technologies such as fixed bed activated carbon adsorption deodorization are used. Even if 90% of odorous substances are removed, the odor concentration perceived by human sense of smell is only reduced by less than half. This determines that the prevention and control of odor is more difficult than the prevention and control of other air pollutants. To eliminate odor, it is dozens to thousands of times more stringent than meeting emission standards. Therefore, it is particularly important to strengthen the control of odor pollution.

[0003] At present, there are various means of purifying high-concentration malodorous waste gas generated in the production process of international and domestic purification and treatment factories, but they have problems to varying degrees, such as high equipment investment, high operating cost, small gas treatment volume, unstable operation, large space occupation, low deodorization and purification efficiency, and secondary pollution. Summary of the invention

[0004] In view of the shortcomings of the above-mentioned existing production technology, the applicant provides a multi-stage industrial odor collection and treatment device with a reasonable structure.

DETAILED DESCRIPTION

[0019] The specific implementation of the present invention will be described below in conjunction with the accompanying drawings.

[0020] like Figure 1 As shown, the present invention mainly comprises a reaction pool 7, a deodorizing bacteria bio-bed 10 is arranged in the middle of the reaction pool 7, and deodorizing bacteria capable of removing organic matter in industrial odor are arranged in the deodorizing bacteria bio-bed 10. The reaction pool 7 is filled with clean water, and the deodorizing bacteria bio-bed 10 is immersed in the clean water.

[0021] like Figure 1 As shown, a plurality of spray towers 2 are arranged side by side on the top of the reaction pool 7, and a ventilation plate 3 is arranged horizontally on the upper part of the spray tower 2, and a plurality of ventilation holes are arranged on the ventilation plate 3 which penetrate from top to bottom. A plurality of spray heads 4 are arranged along the cross-sectional direction below the ventilation plate 3. The plurality of spray heads 4 are evenly distributed along the cross-sectional direction of the ventilation plate 3. A packing layer 5 is arranged horizontally in the middle of the spray tower 2, and the water sprayed on the packing layer 5 forms a uniform water distribution layer, and the odor is fully contacted in the water distribution layer and washed down into the reaction pool 7. A gas blocking nozzle 6 is arranged at the lower end of the spray tower 2, and the gas blocking nozzle 6 extends into the reaction pool 7 and is immersed in clean water.

[0022] like Figure 1 As shown, an air inlet is provided in the middle of the spray tower 2, the air inlet is located below the packing layer 5, and an air outlet is provided at the top of the spray tower 2. The air inlet of the first spray tower 2 among the multiple spray towers 2 is connected to the odor inlet pipe 14, and the odor inlet pipe 14 is provided with a fan 1, which can collect odor in industrial production into the odor inlet pipe 14. The air outlet of the first spray tower 2 of the two adjacent spray towers 2 is connected to the air inlet of the second spray tower 2 through the odor intermediate pipe 15.

[0023] The odor enters the spray tower 2 through the odor inlet pipe 14 and rises. A part of the odor falls after encountering the water sprayed by the spray head 4 in the packing layer 5 and enters the gas blocking nozzle 6. The other part of the odor that has not come into contact with the water enters the next spray tower 2 through the gas outlet at the top of the spray tower 2 for spraying treatment again. Through the multi-stage absorption treatment of multiple spray towers 2, the odor is fully deodorized and purified.

[0024] In order to allow the gas to flow from the gas blocking nozzle 6 to the reaction pool 7 in one direction, Figure 1 and Figure 2 As shown, the air blocking nozzle 6 body is a truncated cone structure with a diameter that increases from small to large from top to bottom, and the lower end surface of the air blocking nozzle 6 is a spherical surface that bulges outward. A plurality of air blocking nozzles 17 are arranged along the edge of the lower end surface of the air blocking nozzle 6, and the plurality of air blocking nozzles 17 are evenly distributed along the circumferential direction.

[0025] The deodorizing bacteria bio-bed 10 generates dirt during the deodorizing reaction process. In order to collect and centrally treat the dirt, Figure 1As shown, a plurality of sludge collecting buckets 11 are arranged side by side at the bottom of the reaction tank 7, the feed ends of the plurality of sludge collecting buckets 11 face the deodorizing bacteria bio-bed 10, and the discharge ends of the plurality of sludge collecting buckets 11 are connected to a sewage pipe 12, which collects the sludge and transports it to the sewage tank for centralized treatment.

[0026] like Figure 1 As shown, a water tank 8 is arranged on one side of the reaction tank 7, a partition 9 is arranged between the water tank 8 and the reaction tank 7, and the top space of the water tank 8 and the reaction tank 7 is connected. When the water level in the reaction tank 7 is too high and exceeds the height of the partition 9, the clean water in the reaction tank 7 enters the water tank 8. The water outlet of the water tank 8 is connected to multiple spray heads 4 of multiple spray towers 2 through a circulating water outlet pipe 16, and a water pump 13 is arranged on the circulating water outlet pipe 16.

[0027] The working principle of the present invention is as follows: the fan 1 collects the odor in industrial production into the odor inlet pipe 14, the odor enters the spray tower 2 through the odor inlet pipe 14 and then rises, a part of the odor falls after encountering the water sprayed by the spray head 4 in the packing layer 5, and enters the gas blocking nozzle 6. The other part of the odor that has not been exposed to water enters the next spray tower 2 through the gas outlet at the top of the spray tower 2 for spraying treatment again, and the odor is fully deodorized and purified through multiple spray towers 2 multi-stage absorption treatment. The spray water mixed with the odor flows unidirectionally into the reaction tank 7 through the gas blocking nozzle 6, and then enters the deodorizing bacteria bio-bed 10, in which deodorizing bacteria capable of removing organic matter in industrial odor are arranged. During the deodorization reaction, waste will be generated. In order to collect and centrally treat the waste, a plurality of sludge collecting buckets 11 are arranged side by side at the bottom of the reaction tank 7. The feed ends of the plurality of sludge collecting buckets 11 face the deodorizing bacteria bio-bed 10, and the discharge ends of the plurality of sludge collecting buckets 11 are connected to a sewage pipe 12. The sewage pipe 12 collects the sludge and transports it to the sewage tank for centralized treatment.
