Organic waste gas treater utilizing attapulgite adsorption and superparamagnetic field magnetolysis

Abstract

The invention discloses an organic waste gas treater utilizing attapulgite adsorption and superparamagnetic field magnetolysis. The organic waste gas treater comprises a treater body and a fan arranged in the treater body. An air outlet is formed in one side face of the treater body, and an air inflow face is arranged on at least one side face of the treater body. The air inflow face is provided with an attapulgite molecular sieve, modified activated carbon and a superparamagnetic field magnetolysis plate from outside to inside. The attapulgite molecular sieve is provided with three layers ofstructures which sequentially comprise a front-layer fine net, a middle-layer honeycomb flow layer and a rear-layer fine net. The honeycomb flow layer is filled with attapulgite particles and wrappedby the front-layer fine net and the rear-layer fine net. According to the waste gas treater, adsorption filtering of an attapulgite adsorption plate and a modified activated carbon adsorption plate and magnetolysis filtering of the superparamagnetic field magnetolysis plate are combined, the waste gas purification rate is higher, attapulgite serves as an adsorbent and red pyroxene serves as a representing agent in the attapulgite molecular sieve, the hydrophobic modification technology of the attapulgite molecular sieve is simpler and has a better effect, and the selective adsorption capacityof the attapulgite molecular sieve for an organic compound can be improved.

Description

technical field [0001] The invention relates to the technical field of waste gas purification, in particular to an organic waste gas processor utilizing attapulgite adsorption and superparamagnetic field magnetolysis. Background technique [0002] Existing organic waste gas treatment technologies: [0003] 1. Liquid absorption technology: The principle of this treatment technology is to realize the fusion of harmful components in organic waste gas and absorbent through physical absorption method and chemical absorption method, and then treat wastewater to achieve the purpose of purification and treatment. The purification rate is <30%, and there is heavy secondary pollution. [0004] 2. Adsorption technology: The use of adsorbents to absorb organic waste gas is suitable for treating low-concentration and small amounts of organic waste gas. The purification efficiency is low (<45%), the regeneration and desorption is difficult (flammable), and it needs to be replaced ...

AI Technical Summary

Problems solved by technology

It is suitable for the treatment of combustible gases with high concentration and small volume, with high purification efficiency, and the organic waste gas is completely oxidized and decomposed. Disadvantages: the equipment is easy to corrode, the treatment cost is high, and it is easy to form secondary pollution;

Disadvantages: The catalyst is easily poisoned, and the input cost and maintenance cost are high;

Disadvantages: high one-time investment, great security risks

[0016] However, the size of the particles filtered by the existing physical filtration technology is still at the PM2.5 level. For particles below PM2.5, especially non-polar small particles with a particle size below 100nm, there is still "helpless".

Moreover, in order to achieve a good filtering effect, multi-stage filtering needs to be set, resulting in complex structure and troublesome installation of the physical filtering device in the prior art; and the service life is short, the maintenance cost is high, and it needs to be replaced again

[0017] The electrostatic precipitator technology is also unable to deal with particles below PM2.5, especially non-polar small particles with a particle size below 100nm. Large, and will generate high-voltage static electricity, endangering human life
