Problems solved by technology

The traditional electrostatic precipitator does not pay much attention to the problem that the aerosol particles themselves are charged, but collects them as neutral particles after charging. Charged aerosols tend to reduce the dust collection efficiency or increase the power consumption of the electrostatic precipitator

Abstract

The invention discloses a magnetoelectric composite gas purification method. The method comprises a particulate matter deflection collection mode, a polarity separation collection mode and a common discharge collection mode, and comprises the following operation steps of 1, entering the particulate matter deflection collection mode, and detecting whether a large number of positively-charged and / ornegatively-charged particles exist in airflow or not; 2, if the large number of particles with positive electricity and / or negative electricity exist / exist, entering the polarity-divided collection mode, and if not, entering the common discharge collection mode, wherein the two collection modes both adopt a concentration sensor feedback adjustment method to determine the discharge voltage and / orthe number of corona wires. The method can detect and judge whether the aerosol particles have charges or not and the approximate proportion of the particles with positive charges, negative charges and neutral charges, and selects the proper collection mode, so that the effects of improving the dust removal efficiency, reducing the use power consumption and reducing the volume of the purifier areachieved.

Description

technical field [0001] The invention relates to a gas purification system, in particular to a magnetoelectric composite gas purification method, which belongs to the field of electrostatic dust removal. Background technique [0002] The electrostatic precipitator is an air purification system commonly used in industry and life. As early as 1772, the scientist Beccaria conducted a successful experiment on the discharge and electric wind phenomenon in a large amount of smoke gas. In 1906, Cottrell Verified the effect of electrostatic force on the purification and filtration of dust-containing gas and applied this treatment process to industry. In 1907, the first electrostatic precipitator was built and successfully processed smoke and dust at industrial sites. Today, electrostatic precipitator technology has been widely used Applied in almost all industrial fields, the principle of electrostatic dust removal is to use a high-voltage direct current electric field to ionize gas ...
