Description

Gas purifier {APPARATUS FOR PURIFICATINGGAS}

The present invention relates to a gas purification device, and more particularly, after discharge is performed by introducing polluted air and gas containing polluted gas, pollutants are collected and purified, and only the purified gas is discharged to the outside. It relates to a gas purification device that can.

In general, in a number of chemical or physical processes, when fine dust, pollutants containing humidity and moisture, oil, etc. are scattered in the air, it may cause very serious environmental problems, and thus these pollutants The problem of treating the air containing this air is recognized as a very important national issue.

In order to filter pollutants emitted from factories, etc. in the air, various technologies need to be connected in a complex way. An electrostatic precipitator that removes the dust has been commercialized.

These electrostatic precipitators ionize contaminants in the air and then remove contaminants from the air by making the ionized contaminants adhere to the dust collecting electrode. to be removed

In addition, the conventional electrostatic precipitator separately includes a filter for filtering foreign substances such as dust. Accordingly, there is a problem in that the filter must be replaced according to a certain period.

In the conventional electrostatic precipitator, when air or gas containing foreign substances is charged, only a part is discharged because the amount of discharge is not uniform in the charged discharge space, and the remaining part is discharged without ionization, so substantially polluted air Alternatively, there is a problem in that the purification efficiency of the gas is lowered.

In particular, when the discharge current flowing between the high-voltage electrode and the counter electrode is increased in order to obtain high dust collection efficiency, ozone (O3) is easily generated along with the discharge. Ozone has a unique odor, so when it is released indoors, it is necessary to keep it below the environmental standard (0.05 ppm) because ozone can cause carcinogens when the concentration is higher than the environmental standard (0.05 ppm).
