Embodiment Construction

[0024] The present invention is described in further detail now in conjunction with accompanying drawing. These drawings are all simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, so they only show the configurations related to the present invention.

[0025] Such as Figure 1~2 A CH of the present invention shown 3 NH 2(g) An embodiment of a waste gas treatment device, including a waste gas absorption oxidizer 1 and a waste water biological aerated filter 20. The waste gas absorption oxidizer 1 is sequentially composed of a waste gas washing and dust removal area 10, an exhaust gas oxidation absorption area 11, and an exhaust gas alkalization absorption area 12 from the bottom up. and exhaust gas acidification absorption area 13, exhaust gas washing and dust removal area 10 is provided with exhaust gas inlet 14, exhaust gas inlet 14 is connected to the exhaust gas collection and delivery system through pi...

Abstract

The invention relates to a CH3NH2(g) waste gas treatment device, which comprises a waste gas adsorption oxidizer and a waste water aeration biological filter, wherein a waste gas washing dust removal region, a waste gas oxidization adsorption region, a waste gas basification adsorption region, a first defogging device, a waste gas acidification adsorption region and a second defogging device are sequentially arranged in the waste gas adsorption oxidizer in an upward direction from the bottom; the waste gas dust removal region is provided with a waste gas inlet; a gas flow guide pyrometric cone is arranged at the waste gas inlet position; the waste gas inlet communicates with a waste gas collection and conveying system through a pipeline; a waste gas outlet is formed above the waste gas second defogging device; the middle and upper part of the waste water aeration biological filter is of a cylindrical structure; the lower part of the waste water aeration biological filter is of a conical structure; the waste water aeration biological filter comprises a lower flow region, an upper flow region and a sludge region.

Description

technical field [0001] The invention relates to the technical field of waste gas treatment, in particular to a CH 3 NH 2(g) Exhaust gas treatment device. Background technique [0002] CH 3 NH 2(g) It is one of the typical representative methylamine odorous gases. CH 3 NH 2(g) It is a small molecular organic amine, which is widely used in agricultural chemicals (insecticides, fungicides, herbicides, etc.), pharmaceuticals, surfactants (soap detergents, shampoos, cleaning agents, etc.) and photo imaging agents. use. CH 3 NH 2(g) The smell threshold is low, and there is a strong irritating fish odor at low concentrations. Due to its simple molecular structure, stable properties, and difficult biochemical degradation, it has become one of the air pollutants that seriously threaten personal safety and urgently need to be treated. [0003] CH 3 NH 2(g) The removal of malodorous gases can be generally divided into two categories: gas phase treatment and liquid phase tr...
