Combined air purifier

Abstract

The invention relates to a combined air purifier. The combined air purifier is provided with a purified air inlet and outlet channel. A water filter element, an electrostatic precipitator, a heating dehumidifier, a composite active carbon layer and a fan are upwards stacked at the bottom of the purified air inlet and outlet channel in sequence. The water filter element comprises a water tank, a water pump, a water supply pipe, a water spraying cavity and an outer frame. The outer frame is arranged above the water tank and communicates with the water tank. Filler is accommodated in the outer frame and is of a net structure made from compressed impermeable flexible materials. An air inlet and an air outlet are formed in the outer frame. Water in the water tank is pumped into the water spraying cavity by the water pump through the water supply pipe, and water in the water spraying cavity is sprayed to the filler below the water spraying cavity. According to the combined air purifier, through three-stage filtering by the water filter element, the air purification effect is good; the specific area of the water filter element is greatly improved, so that the contact time between water and air is prolonged, and accordingly, the purification efficiency is improved; and meanwhile, the problem that the humidity of exhausted air is too large is solved.

Description

technical field [0001] The invention relates to an air purifier, in particular to a combined air purifier. Background technique [0002] The air purifiers in the prior art are generally dry-type purifiers. Although they have the effect of removing harmful gases in the air, they need to replace the filter element regularly, which is costly and not environmentally friendly. [0003] However, the existing wet air purifiers generally use water curtain or spray to filter the air. Both types of products have insufficient water specific surface area, insufficient contact time between water and air, and excessive humidity of the discharged air. question. Contents of the invention [0004] The purpose of the present invention is to provide a combined air purifier, which uses water as the purification medium, does not need to replace the filter element, saves cost and is environmentally friendly; at the same time, it increases the contact time between air and water and reduces the ...
