Biofilter capable of adjusting temperature and humidity and use method thereof

Abstract

The invention discloses a biofilter capable of adjusting temperature and humidity. The biofilter comprises a filtering tower, an organic exhaust gas feeding pipe, a liquid supplying tank and a controldevice; a screen is arranged in the middle of the filtering tower; a filler layer loaded with bacteria and microorganisms is filled in the screen; a plurality of layers of film cloth are stacked at the lower part of the filtering tower; the liquid supplying tank stores water; the filtering tower penetrate through a microorganism spraying pipe; water does not leak from the filler layer to the bottom of the filtering tower; the organic exhaust gas feeding pipe is provided with a temperature adjusting and controlling structure, a humidity adjusting and controlling structure, and a controlling device; the controlling device is respectively connected with the temperature adjusting and controlling structure and the humidity adjusting and controlling structure and controls the operation of the both. The biofilter of the invention has the advantages of adjusting temperature and humidity, and conveniently cleaning the filtering tower.

Description

technical field [0001] The invention belongs to the technical field of waste gas treatment, and in particular relates to a temperature-adjusting-humidity-regulating biological filter device and a use method thereof. Background technique [0002] VOCs (Volatile Organic Pollutants), as the precursors of ozone generation, are one of the organic waste gases. Among the traditional organic waste gas treatment technologies, there is a method of treating organic waste gas by spraying and biological decomposition. The advantage of this method is that microorganisms use organic waste gas as a carbon source and energy source for growth, and oxidize organic waste gas into inorganic substances, and their degradation efficiency is high. However, the biological trickling filtration method also has shortcomings, that is, the growth of microorganisms is not easy to control, and the temperature may be high or low when the organic waste gas is charged, which will affect the survival of microo...

AI Technical Summary

Problems solved by technology

However, the biological trickling filtration method also has shortcomings, that is, the growth of microorganisms is not easy to control, and the temperature may be high or low when the organic waste gas is charged, which will affect the survival of microorganisms, and because the microorganisms need to be continuously sprayed, There must be a pool under the filter tower to receive water, and microorganisms will produce metabolic waste, which will fall into the pool and settle, resulting in more and more sludge at the bottom of the pool, which is difficult to clean
