A method and device for using static electricity to adsorb non-gaseous substances in gas

Abstract

The invention discloses a method for adsorbing non-gaseous matter in gas through static electricity. The method for adsorbing non-gaseous matter in gas through static electricity comprises the steps that firstly, a gas filter channel is arranged, a plurality of face-shaped adsorption components made of conductor materials are arranged in the channel sequentially, and gaps allowing gas to pass through are formed in the adsorption components; secondly, the adsorption components are connected with a power source, so that static electricity is generated on the adsorption components, and the voltage of the adsorption component is made as high as possible under the condition that air ionization is avoided; and thirdly, the to-be-filtered gas is made to flow through the gas filter channel, particulate matter in the gas is adsorbed on the adsorption components through static electricity, and the adsorption components are cleaned online through a cleaning device when the quantity of matter on the adsorption components reaches a certain degree. By adoption of the method, gas can be filtered rapidly and efficiently, and the method is suitable for being applied to various fields such as industrial dedusting and hazy and foggy air purification.

Description

technical field [0001] The invention relates to the technical field of gas filtration, in particular to a method and a device for using static electricity to adsorb non-gaseous substances in gas. Background technique [0002] At present, the problem of air quality has become a major health problem affecting human beings. Human beings live in hazy weather for a long time, which will increase the risk of various respiratory system and cardiovascular and cerebrovascular diseases, affect the quality of life, and shorten the life expectancy. Smog weather, especially the smog weather caused by the excessive concentration of particulate matter in northern cities in winter in my country, is extremely harmful to people's health. At present, my country's control of particulate matter emissions, in addition to strengthening legislation and standardizing production, still lacks action. It is an effective and economical method to remove fine particles. [0003] Among the current methods ...

Human beings live in hazy weather for a long time, which will increase the risk of various respiratory system and cardiovascular and cerebrovascular diseases, affect the quality of life, and shorten the life expectancy.

Smog weather, especially the smog weather caused by the excessive concentration of particulate matter in northern cities in winter in my country, is extremely harmful to people's health. At present, my country's control of particulate matter emissions, in addition to strengthening legislation and standardizing production, still lacks action. An effective and economical method for removing fine particles

[0003] Among the current methods of filtering gas, electrostatic filtration is a relatively common method. Dust-containing gas is electrically separated when it passes through a high-voltage electrostatic field. The filtering effect of this method is affected by the specific resistance of dust particles, and the cleaning of solid particles requires shutdown processing, which cannot be processed online, which affects continuous dust removal
