Tiny dust dustfall agent, preparation method thereof and desulfurization dustfall method

Abstract

The invention relates to the technical field of environmentally-friendly dust removal technology, in particular to a tiny dust dustfall agent, a preparation method thereof and a desulfurization dustfall method. The tiny dust dustfall agent is prepared by mixing deionized water and the following raw materials in parts by weight: 30 to 50 parts of a polyoxyethylene-polyoxypropylene copolymer, 10 to20 parts of sodium polyacrylate, 15 to 20 parts of alkyl polyglucosides, 10 to 15 parts of ethylene diamine tetramethylene phosphonic acid sodium, 10 to 15 parts of ethyl alcohol and 2 parts of a preservative. By using the effects of the polyoxyethylene-polyoxypropylene copolymer, sodium polyacrylate, alkyl polyglucosides, ethylene diamine tetramethylene phosphonic acid sodium, ethyl alcohol and the preservative, in the desulfurization solution of a flue gas desulfurization technology, the tiny dust dustfall agent prepared from the components is added, the characteristic of the desulfurizationsolution can be changed, and the adhesive force for dust particles is increased, so that the effect of dustfall effect is greatly improved, the desulfurization performance can be improved in the desulfurization technological process, and the sedimentation effect for tiny dust can be increased.

Description

technical field [0001] The invention relates to the technical field of environmental protection and dedusting, in particular to a fine dust dedusting agent, a preparation method thereof and a desulfurization and dedusting method. Background technique [0002] At present, in the desulfurization process stage of the coal-fired flue gas discharge process in power plants, chemical plants, and heating furnaces, the "desulfurization solution" as the main medium for desulfurization usually adopts the spraying operation mode during the desulfurization process. Most of the components of the desulfurization solution are water; at the same time, in the operation of wet dust suppression and dust removal, "spray" is also the main operation mode. [0003] However, in the process of flue gas emission, if only the desulfurization solution is sprayed, because the desulfurization solution only uses its chemical reaction to desulfurize, and the physical property "dust fall" of the solution has...

Problems solved by technology

[0003] However, in the process of flue gas discharge, if only the desulfurization solution is sprayed, because the desulfurization solution only uses its chemical reaction to desulfurize, and the physical property "dust fall" of the solution has not been changed, just like ordinary water, due to Surface tension, the natural hydrophobicity of dust (especially the finer dust is more hydrophobic), so an opportunity to effectively reduce dust is wasted
