Tubular washing type air purifier

Abstract

The invention relates to an air purifier, belonging to the field of household electrical appliances. The air purifier overcomes the technical problems of low steam mass transfer efficiency and non-ideal purifying effect of conventional washing type air purifiers. The air purifier provided by the invention simulates air-liquid mixing and pressurized purification in an intestinal tract-like long tube and comprises a water circulation unit, an air circulation unit, a water filtering unit and an air filtering unit. According to the invention, a water pump is connected with an ejector and a staticmixer; air filtered by a filter screen is sucked in and allowed to form uniform and fine bubbles which fully contact with water, so the contact area and action time of the air and the water are improved; and in the long tube with a length of 9 meters, the bubbles wrapped in water do not combine with each other nor rupture under the action of the thrust of the water pump and the resistance of the water tube and undergo collision flowing, so steam mass transfer effect is improved, and the purification process of air by rain is basically simulated. The purifier has good purifying effect, low cost, small noise and no secondary pollution, and is capable of humidifying air, easy for scaling up and extensively applicable to indoor use.

Description

technical field [0001] A tubular water washing air purification device designed in the present invention uses a new method of uniform mixing of gas and liquid and pressurized purification in a long tube by applying physical methods. By prolonging the effective purification time of gas and liquid and increasing the actual contact area of ​​gas and liquid, the The water-air mass transfer movement solves the technical problems of low water-air mass transfer efficiency and unsatisfactory purification effect of the water-washed air purifier. Background technique [0002] There are many kinds of air purifiers on the market, most of which are filter-type air purifiers. Their cost is high and the consumables are expensive. Harmful to the human body; photocatalytic air purifiers, currently immature technology, are prone to produce harmful substances; water-washing air purifiers are getting more and more attention, but there is a problem that has not been overcome: low mass transfer e...

AI Technical Summary

Problems solved by technology

It basically simulates the purification process of water droplets on the air when it rains in nature, the collection of mountain streams, and the splashing of waterfalls. Under the premise that the total volume of the purifier remains unchanged, it solves the problem of short mass transfer time between water and air and the contact area of ​​water and air per unit time. Small size, inactive water-gas mass transfer activity, and unsatisfactory purification effect
