Description

Technical Field

[0001] The utility model relates to the technical field of biological deodorization, in particular to an anti-clogging high-concentration waste gas biological deodorization tower. Background Art

[0002] Biological deodorization is a waste gas treatment technology that uses domesticated microorganisms to oxidize and decompose malodorous substances into odorless carbon dioxide, water, minerals, etc., thereby achieving the purpose of purifying malodorous gases. In the process of oxidizing and decomposing malodorous substances, microorganisms can also convert malodorous substances into their own nutrients and continue to reproduce.

[0003] The various microorganisms used in the biological deodorization process have their maximum biochemical treatment capacity. For the same biochemical deodorization tower, the odor concentration of the inlet air is within a certain range, and the microorganisms on the biofilm can effectively degrade the odor substances. However, when the inlet concentration is too high, the deodorization tower will be blocked due to the decrease of microbial activity, overload of the packing layer, accumulation of microbial metabolites, etc., causing a series of environmental impacts and safety risks. Therefore, the problem of easy blockage of high-concentration waste gas biological deodorization needs to be solved urgently. Utility Model Content

[0028] Working principle: First, by monitoring the changes in the inlet and outlet pressures of the three deodorizing towers in operation, when the inlet pressure is normal but the outlet pressure increases significantly, it can be considered that the deodorizing tower is blocked. Assuming that the third biological deodorizing tower 3 is blocked, at this time, close the third air inlet valve 14, stop the operation of the third biological deodorizing tower 3, open the fourth air inlet valve 9, start the fourth biological deodorizing tower 4, then start the dosing pump 6, open the third dosing valve 12, and transport the sodium hypochlorite disinfectant in the sodium hypochlorite storage tank 5 to the third biological deodorizing tower 3. When the pH value in the third biological deodorizing tower 3 reaches 8 to 9, stop adding the sodium hypochlorite solution, and then start the third circulation pump 16 to circulate the sodium hypochlorite solution in the third biological deodorizing tower 3 to better kill microorganisms and their metabolites and solve the resulting blockage problem. After the third circulation pump 16 runs for a period of time, it stops running, and the third drain valve 13 is opened to discharge the sewage generated during the disinfection process into the sewage treatment system through the drain pipe. Finally, the third water inlet valve 15 is opened to transport clean water to the third biological deodorization tower 3, and the third circulation pump 16 is started to flush the deodorization tower multiple times. After the blockage problem is solved, the third biological deodorization tower 3 can be switched and put into use again without interruption when other deodorization towers are blocked.
