Liquid-washing air filter

Abstract

The invention discloses a liquid-washing air filter which comprises an air feeding device and a filtering cavity. The filtering cavity is provided with an air inlet and an exhaust port, and liquid can be injected into the filtering cavity; the air feeding device can feed air into the filtering cavity and enable the air to be mixed with the liquid and then exhausted from the exhaust port, and a draught fan or an air blower or an air compressor or an air feeding or air sucking device of a dust collector or air purifier can be adopted as the air feeding device; by mixing the air with the liquid, pollutants in the air are effectively adsorbed, and lastly the purified air is exhausted from the exhaust port; the air purifying process is completed in the closed cavity, the filtering efficiency is high, the filtering effect is good, the air feeding and filtering process can be completed through the air feeding or air sucking device in the dust collector or air purifier, the original air dynamic of the dust collector or air purifier is fully utilized, equipment does not need to be additionally arranged, miniaturized compact arrangement is facilitated, the cost is saved, and the filtering effect is enhanced.

Description

technical field [0001] The invention relates to an air filter, in particular to a liquid-washed air filter. Background technique [0002] Water and other liquids naturally have good adsorption capacity for air pollutants such as microorganisms (for example, bacteria, viruses, molds) and particles (for example, dust). This is because, in the process of falling rainwater, the pollutants in the air are adsorbed and flowed into the river. According to this principle, at present, people deliberately add water curtains or spray water through water mist spraying vehicles on air-conditioning fans or ventilation fans. Fog, in order to achieve a certain air filtration effect, but either the effect is not satisfactory, or it needs to rely on large-scale equipment to achieve. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the present invention provides a liquid-washed air filter that can be used for air purifiers, vacuum cleaners and the li...
