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 ...

AI Technical Summary

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 ideal. It can be said that it is not difficult for an electrostatic precipitator to achieve high efficiency. The difficulty is how to keep the plates clean, for example:

[0005] ①The electrostatic precipitator for dust removal generally has a vibration device, which knocks the plate intermittently to make the dust fall off the dust collecting plate. Due to the narrow space of the plate and the high voltage environment, the vibration device It is very complicated, the cost is very high, and the process of dust falling off will cause a lot of secondary pollution, so the capacity of the whole machine has to be increased

[0006] ② There are still some equipment that adopts mechanical scraping method, but the structure is complicated and the precision is high, so the cost is high and there are many failures. Moreover, because of the high-pressure environment, the scraping must be carried out in a shutdown state, so that the equipment cannot run continuously
