A deodorizing device with sheet filler

Abstract

The invention relates to a gas processing device, in particular to a deodorizing device with a flaky filler. A circulating water system in the deodorizing device is arranged on the side surface of the deodorizing device; a gas inlet is formed at one end of the deodorizing device; a gas outlet is formed at the other end of the deodorizing device; the gas inlet and the gas outlet are both connected with a gas distributing device; a bottom water tank is arranged at the bottom of the whole deodorizing device; a top water-distributing and moisture-retaining device is arranged at the top of the whole deodorizing device. The flaky filler increases the effective area of a biofilm to 2-4 times that of spherical filler; the biofilm has a self-cleaning function and can maintain biological activity and constant total film amount for a long time, so as to ensure the smoothness of a gas processing passage and solve the problem that the lower layers of other fillers cannot form films because the biofilms increase and microorganisms die and accumulate; increase of wind resistance and energy consumption and reduction of a processing effect are solved better; the volume of the biological filler is reduced by half, so that the manufacturing cost is saved, operation and management are easier and the cost is lower.

Description

technical field [0001] The invention relates to a gas treatment device, in particular to a VOC gas treatment device using biofilm, in particular to a deodorizing device with a sheet-shaped filler. Background technique [0002] Biofilm deodorization is a biological waste gas treatment technology that uses a biological method to deodorize odor molecules through a microbial film specially cultivated on the biological filler in the biofilter. There are three substances: gas, liquid and solid in the biofilter. , relying on the biofilm formed by high-efficiency microbial strains on the biological filler, (solid phase and liquid phase) to purify and degrade the pollutants in the exhaust gas (gas phase), the biofilm (solid phase) continues to increase during operation, in order to maintain the gas The unimpeded flow of the biofilm (solid phase) that has died and failed is washed away by spraying water (liquid phase). The main function of the bio-filler is to serve as the carrier of...

AI Technical Summary

Problems solved by technology

At present, biological deodorization fillers mainly include bark organic fillers, plastic fillers, ceramsite fillers, and carbonaceous fillers. Microorganisms continue to silt, and the gas channels become smaller or even blocked, so that microorganisms cannot grow and hang films in the middle and lower parts of the filler, which eventually leads to a great reduction in the effective treatment area of ​​the overall biofilm

In order to keep the gas unblocked, the excess dead biofilm is washed away by spraying water in the process. The amount of spraying water in the process is very difficult to control. If the amount of spraying water is too large or too small, the treatment effect will be unsatisfactory or the wind resistance will be large.
