Civil air-cleaning device

Abstract

The invention provides a civil air-cleaning device. A fan drives air to pass through a steam fog generator, the air is mixed with fog drops, and pollutants in air transfer to the fog drops. Liquid in a gas-liquid mixture is separated by a cyclone separator, and purified air is outputted. Steam fog is circulated and generated by separated liquid. During the working process of the apparatus, liquid is timely updated or cleaned, so that pollutant-removing capability is kept.

Description

technical field [0001] The invention relates to a novel air purification device, in particular to a device for purifying dirty air containing fine particles, nitrogen oxides and total organic carbon. Background technique [0002] In recent years, the air quality has deteriorated day by day, posing a threat to people's health. At present, the working methods and principles adopted by air purification devices mainly include eight kinds of filtration, electrostatic, adsorption, ultraviolet, photocatalysis, liquid bubbling, liquid film washing, and Venturi tube method. [0003] The filter purification device adopts one-stage or multi-stage filter screen, filter membrane or filter element, which can filter and remove particulate matter in the air. The filter unit has a large volume, and the filter device is easy to block after long-term operation, the resistance increases, the energy consumption increases, and the purification effect decreases. Filter units are often difficult ...

AI Technical Summary

Problems solved by technology

The water pressure loss of the Venturi tube is generally 0.1-0.3MPa under the best working condition, the energy consumption per unit of gas volume is high, and the weight of the power equipment is also large

The Venturi tube itself is small in size, but generally requires a large installation and operation space

In addition, the processing and production of Venturi tube is relatively cumbersome
