The invention discloses an electrostatic spraying method. The electrostatic spraying method comprises the following steps: assembling equipment composed of an electrostatic spraying device, a water tank, a bottom frame and a dust removal tower, wherein a dust-containing waste gas inlet through which pollutant particles and acid mist electricity enter is formed in the top of the dust removal tower; enabling the pollutant particles and the acid mist electricity to be charged through double-fluid sprayed mist generated by the electrostatic spraying device mounted at an electrostatic spraying mounting opening; increasing the mass (by carrying out fusion on the sprayed mist) and increasing the particle diameter (through a coagulation effect); enabling pollutants and water mist to be charged with negative electricity; grounding a shell of a dust remover to obtain a positive electrode; and enabling the pollutants to be deposited on a shell body of the dust remover and flushing the pollutants into the water tank at the bottom through the sprayed mist and exhausting purified gas through a purifier outlet. The electrostatic spraying method disclosed by the invention adopts the charged double-fluid sprayed mist and can be used for carrying out efficient adsorption and sedimentation on the pollutant particles with relatively small grain diameters and the acid mist electricity in dust-containing waste gas; and the electrostatic spraying method has the advantages of stronger practicability, simplicity in building, low cost and wider applicability.
Description
technical field [0001] The invention relates to the technical field of environmental protection, in particular to a charged spraying method. Background technique [0002] At present, dust removal equipment is used in various production industries and environmental protection fields to discharge exhaust gas. The dust removal equipment used is various, but for the exhaust gas containing some small particle sizes and acid mist electricity, these settlements are difficult. The existing dust removal equipment The dust removal method adopted by the equipment cannot achieve the ideal dust removal effect, and the emission quality is poor, which seriously affects the production and ecological environment. [0003] Therefore, in order to solve the above problems, it is an urgent problem for those skilled in the art to develop a dust removal method for the dusty exhaust gas with small particle size and acid mist. Contents of the invention [0004] Aiming at the deficiencies in the p...
