Abstract

The invention relates to an air purification device which comprises a water tank and a barrel body, wherein a water tank filter screen is arranged in the water tank, and the bottom of the barrel body is arranged on the water tank filter screen; a filter screen, electrode plates and an exhaust fan are sequentially arranged in the barrel body from bottom to top. The air purification device utilizes the exhaust fan to form a low-pressure area in the barrel body. External air quickly enters into alkaline solution water bath from the water tank below and then enters into the barrel body, suspended particles in the air are absorbed by water molecules to sink to the bottom of the water tank, and acidic oxides such as CO2 in the air react with an alkaline solution to be removed. Purified air passes through the (high voltage) electrode plates in the barrel body so as to be ionized to generate a lot of anions, and finally, the original polluted air is changed into healthy and clean air which is then exhausted to a needed environment through the exhaust fan. Thus, the air purification device can be used for clearing atmospheric haze and waste gas effectively and has a large air purification range and a useful effect.
