Chemical agglomeration promoter for removing fire coal fine particulate matters and application method of chemical agglomeration promoter

Abstract

The invention discloses a chemical agglomeration promoter for removing fire coal fine particulate matters. The chemical agglomeration promoter is prepared from poly-dimethyl-diallyl-ammonium chloride, sorbitan fatty acid ester and water, wherein the mass percent of poly-dimethyl-diallyl-ammonium chloride is 0.001%-0.01%; and the mass percentage of the sorbitan fatty acid ester is 0.001%-0.1%. The invention also discloses an application method of the chemical agglomeration promoter. The chemical agglomeration promoter is capable of effectively promoting fine particles in a gas flue to agglomerate and flocculate to form large particles, and carrying out integral removal on heavy metals in a flue gas; the efficiency of a dust remover for removing fine particulate matters is improved; and the environment problem is effectively relieved.

Description

Technical field [0001] The invention involves a promotional agent of a fine particle, especially a chemical reunion promoter for removing coal -fired particles.At the same time, the present invention also involves the use of the chemical reunion promotion agent. Background technique [0002] my country is currently the largest coal production and consumer country in the world. Coal -fired ash particles are one of the main sources of air pollutants in my country.The pollution problem of coal -fired fine particles (PM2.5) is more serious. Fine particles are usually rich in a large amount of toxic trace elements and organic pollutants, and they are easily inhaled by the human body, which seriously endangers human health.At the same time, these fine particles are also important factors that induce major environmental time such as global climate change, smoke time and ozone layer damage.my country promulgated the new "Environmental Air Quality Standards" in 2012, which stipulates the ...

Problems solved by technology

Chemical agglomeration flocculants are generally composed of binders, surfactants, water and other additives. Agglomeration flocculants can promote the agglomeration of fine particles in front of the electrostatic precipitator to large particles within a certain range, but the agglomeration efficiency is relatively limited, only 30 %, and the formula contains acidic substances such as phosphoric acid, which will cause a certain degree of corrosion to the flue equipment. In addition, the composition of the agglomerating agent solution is complex, and there are certain requirements for the pH of the solution. The configuration process is complicated, and it is not suitable for large-scale industrial production.
