The invention relates to a polar plate of novel electrostatic dust-collection purifying equipment. The polar plate is a cloth dust-collection polar plate stained with conductivity water, and the conductivity water is sprayed, sprinkled or soaked on the cloth dust-collection polar plate; the cloth dust-collection polar plate can be a tracked polar plate of which two ends are sheathed on rolling wheels, and the end of the tracked polar plate is provided with a conductivity water spraying device and a dirt-removal scraping sheet; or the conductivity water spraying device is arranged above the cloth dust-collection polar plate; or a double-roller device and a conductivity water tank are arranged below the cloth dust-collection polar plate, the cloth of the cloth dust-collection polar plate is driven by the double-roller device and is soaked and cleaned by the conductivity water, and the cloth dust-collection polar plate is lined or adhered with a metal polar plate; the conductivity water comprises water containing impurities or conductive chemical solution or water containing chemical solution. The polar plate of the novel electrostatic dust-collection purifying equipment can realize no-cleaning operation or high-voltage off-site cleaning, keeps the stability and high purifying rate of an electric field, has no secondary pollution and long service life and has great effect on environment protection.

Description

technical field [0001] The invention relates to the technical field of environmental protection, in particular to a novel electrostatic dust removal and purification equipment. Background technique [0002] Electrostatic dust removal purification equipment is an environmental protection equipment that uses the effect of electric field on charges to separate pollutants from the air. Among the existing purification equipment, the purification efficiency of fine particles is the highest, which can be higher than 99%. The application is very extensive. The basic principle is: the high-voltage corona electric field ionizes the surrounding air to generate a large number of electrons (or ions). When passing through the corona electric field, under the action of the induced electric field of electrons (or ions), the electrons (or ions) are adsorbed on the pollutant particles to charge the pollutant particles, and they will be subjected to a force in the direction of the opposite ...

Problems solved by technology

[0004] Although the purification efficiency is very high, it is very difficult to maintain this high efficiency

The trapped pollutants are continuously deposited on the plate, and the voltage will be consumed on the pollution layer, reducing the electric field voltage, while the power supply often builds a higher voltage in order to maintain the current, and the local electric field with less pollution will hit wear, the electric field is zero, and the pollutants attached to the plate are not cleaned up in time, so there is no purification

Therefore, various electrostatic precipitators are equipped with different cleaning devices according to the different characteristics of the pollutants. Under high-voltage environments, the design and manufacture of these devices are very complicated, and some are even more complicated than the structure of the electrostatic precipitator itself. Much larger, much larger, much higher cost, and the effect is not i
