Self-circulating type malodorous exhaust gas removal device for biofilter

Abstract

The invention discloses a biological filter self-circulating type deodorizing waste gas device, which comprises a closed deodorizing cover connected to one side of the biological filter through a rotatable support arm, a rotating power source and a telescopic connecting rod. The pressurized sealing belt is fastened above the biological filter, and the top of the closed deodorizing cover is also connected with an acid spray device, a telescopic honeycomb deodorizing mesh, several blowing devices, and an alkali spray device. , the telescopic honeycomb deodorizing mesh is connected to the telescopic servo power source through the fixed cover body and the telescopic shaft; the closed deodorizing cover is connected to the circulating air pipe in sequence through the pressure relief electromagnetic valve, the barometer and the air pressure sensor, and the circulation The trachea is also connected to the bottom of the biofilter; the bottom of the biofilter is connected with several suspension devices. The application provides a deodorizing device that circulates and removes odor in a vacuum-tight environment, while stirring vertically and vertically, and sets a circulating disturbed gas at the bottom of a biofilter.

Description

technical field [0001] The invention relates to the technical field of biological filter malodorous waste gas treatment equipment, in particular to a biological filter self-circulating malodorous waste gas removal device. Background technique [0002] In oil refining, chemical and other enterprises, there are many production units or facilities that will produce foul-smelling exhaust gas, which has become an important source of pollution for such enterprises. Odor pollution sources in oil refining, chemical and other enterprises mainly include storage tank volatilization and sewage treatment system escape. The composition and concentration of the malodorous exhaust gas vary greatly with the different pollution sources, and there are great changes with the change of operating conditions and climate. Therefore, it is difficult to purify these waste gases. The main pollutants in malodorous exhaust gas include: VOC (volatile organic compounds), hydrogen sulfide, ammonia, etc. ...

AI Technical Summary

Problems solved by technology

[0003] In the prior art, the foul-smelling waste gas produced in the process of sewage treatment generally uses a biofilter. Although this technology can effectively remove the bad-smelling waste gas, it has the following disadvantages: ① High power consumption; ② The equipment occupies a large area and high investment; ③, Need to configure nutrient solution and other difficult operations
