Air purifier and method thereof

Abstract

The objective of the present invention is to provide an air purifier and method thereof, capable of clearing away mephitis and air pollution substance generated by an odor source. The air purifying method includes an oxidation process, an acidic and alkaline cleaning process, and is capable of simultaneously clearing away basic group, acidic group and neutral group malodorous substance. In the oxidation process, a water solution containing oxidant is contacted with the malodorous gas to oxygenize and decompose the malodorous substance; in the acidic and alkaline cleaning process, a water solution containing acidic or alkaline cleaning agent is contacted with the malodorous gas, and the cleaning agent absorbs the malodorous substance to chemically neutralize. By means of a chlorine dioxidegenerator, the chlorine dioxide generated by the chlorine dioxide generator is mixed with substance of the malodorous gas in a rapid oxidation device, wherein the substance may be cleared away through oxidative decomposition; the chlorine dioxide is contacted with the alkaline malodorous substance to perform acidic cleaning in an acidic cleaning reaction chamber; the sodium hydrate generated by the chlorine dioxide generator is contacted with the acidic malodorous substance to perform alkaline cleaning and neutralize the acidic cleaning agent so as to prevent residual deodorant from becoming another pollution source.

Description

technical field [0001] The invention relates to an air purifier and a method thereof, which is an air purifying device related to removing stench and air pollutants generated in foul smell sources such as polluted waste water, livestock waste water, excrement and urine, and food waste stations. Specifically, its purification process includes an oxidation process and an acidic and alkaline cleaning process, which can remove alkaline, acidic, and neutral odorous substances at the same time. In the oxidation process, the aqueous solution containing an oxidant will oxidize and decompose the malodorous substance after contacting with the malodorous gas; in the acidic and alkaline cleaning process, the aqueous solution containing an acidic or alkaline cleaning agent will produce a chemical neutralization reaction after contacting the malodorous gas , the malodorous substance is absorbed by the detergent in the aqueous solution.

AI Technical Summary

Problems solved by technology

[0007] The currently developed deodorization devices still have certain limitations in removing the odor generated by environmental infrastructure such as sewage treatment stations, incineration stations, food waste treatment facilities, and landfills.

In particular, various deodorization methods are directly used without seriously considering the properties and types of odorous substances, resulting in the fact that they cannot be completely treated.

Especially in places where high-concentration odorous livestock wastewater and food waste treatment stations are used, unsuitable models are installed in combination with other models, which leads to problems such as high installation costs and large installation space.

Moreover, some models will produce secondary pollution during operation, so secondary treatment is required for other odors or by-products produced by them

At the same time, the original acid-alkaline scrubber still has problems such as large volume, complex structure, large consumption of cleaning agent, high installation and operation costs, etc.
