Description

Technical Field

[0001] The utility model relates to the technical field of waste gas treatment, and more specifically, to a bio-trickling odor treatment device. Background Art

[0002] Microbial trickling filtration is a technology that uses the nutrient needs of microorganisms during their metabolic process to purify waste gas. In this process, malodorous gases or organic pollutants in the waste gas are used as energy or nutrients for microorganisms and degraded into harmless small molecules such as carbon dioxide, water and cellular substances through the metabolic activities of microorganisms.

[0003] In order to remove the odor in the exhaust gas, the existing thermal power plant odor treatment device basically simply absorbs sulfur dioxide and nitrogen dioxide to remove the odor in the exhaust gas. As a result, the treated sulfur dioxide and nitrogen dioxide do not meet the emission standards, and there are still gases with pungent smells in the exhaust gas, and the exhaust gas odor treatment effect is not good.

[0004] After searching, the Chinese patent with application number CN201920174713.8 discloses an exhaust gas odor treatment device, which allows the exhaust gas to be passed into the interior of the filter box through the air inlet pipe, and then uses the water adding pipe to pass clean water into the spray pipe, and then sprays the exhaust gas to remove dust in the exhaust gas. Due to the setting of the filtering device, dust particles fall on the filter plate, and water flows into the interior of the filter box. Then, a water pump is used to send the water inside the filter box back to the spray pipe, so that the spray water can be circulated, avoiding the waste of water resources, thereby improving the practicality of the treatment device.

[0005] When the above-mentioned exhaust gas odor treatment device is actually used, organic matter in the exhaust gas may gradually accumulate on the filter, forming a thick layer of dirt, resulting in a reduction in the filtration area of the filter, thereby affecting the speed and efficiency of the exhaust gas passing through, and further reducing the exhaust gas treatment effect.

[0012] As a further description of the above technical solution: a spray mechanism is installed inside the dust removal tank, and the spray mechanism includes a second motor, a support frame is installed at the output end of the second motor, a diversion box is installed on the top of the support frame, and the bottom of the diversion box is connected to multiple spray pipes, and the bottom end of the spray pipe is connected to multiple spray heads.

[0013] By adopting the above technical solution: using the support frame to drive multiple diversion boxes to swing inside the dust removal tank, the spray water can be evenly sprayed into the dust removal tank, increasing the contact range between the exhaust gas and the spray water.

[0014] As a further description of the above technical solution: the top of the dust removal tank is connected to an exhaust pipe, one end of the exhaust pipe is connected to an exhaust pump, the output end of the exhaust pump is connected to an air supply pipe, one end of the air supply pipe is connected to a filter box, a circulation pump is provided on one side of the filter box, the output and input ends of the circulation pump are connected to a circulation pipe, and a plurality of activated carbon filter plates are provided inside the filter box, and the activated carbon filter plates are plugged and fixed to the inner side of the filter box.

[0015] By adopting the above technical solution: the gas inside the dust removal tank is extracted by an air pump, and the gas is transported to the inside of the filter box for circulation filtration, so as to better absorb the odor in the gas.

[0016] As a further description of the above technical solution: one side of the dust removal tank is connected with an air intake pipe and a sewage discharge pipe, and the air intake pipe is arranged above the sewage discharge pipe.

[0017] By adopting the above technical solution: the air inlet pipe is convenient for conveying the exhaust gas into the dust removal tank, and the sewage pipe is convenient for discharging the spray water and impurities after spraying to the outside of the dust removal tank.

[0018] Technical effects and advantages of this utility model:

[0019] 1. Compared with the existing technology, by setting up a cleaning component, a movable plate is used to drive multiple insertion rods to insert into the filter hole, thereby cleaning the inside of the filter hole, and then multiple rotating plates are used to drive the scraper to move the impurities to the inside of the sewage trough. This can effectively reduce the pollutants and impurities attached to the filter net, improve the exhaust gas passing efficiency, and thus improve the exhaust gas treatment effect;
