Nanometer photocatalytic plasma biological deodorization method and full automatic peculiar smell control deodorization system

Abstract

The invention relates to a nanometer photocatalytic plasma biological deodorization method. The method comprises the following steps of: a, pre-charged dust collection; b, plasma purification; c, plant extract purification, namely atomizing plant extract to form liquid drops with a diameter of less than 1 mu m and performing purification on the liquid drops; and d, nanometer photocatalytic purification. A nanometer photocatalytic plasma biological deodorization method comprises a primary purification room and a secondary purification room, wherein an outlet of the primary purification room is connected with an inlet of the secondary purification room; the primary purification room is provided with coarse filtering equipment, static dust collecting equipment, a photocatalyst, a plasma purification system and a negative ion generator in sequence from the inlet to the outlet; the secondary purification room is provided with a spray atomizer which atomizes the plant extract stored in the system to form the liquid drops with the diameter of less than 1 mu m; and an outlet of the secondary purification room is connected with an exhaust system. The system has the characteristic of good deodorization effect.

Description

A nano-photocatalytic plasma biological deodorization method and a fully automatic odor control deodorization system technical field The invention relates to the technical field of odor removal, in particular to a nano-photocatalytic plasma biological deodorization method and a fully automatic odor control deodorization system. Background technique 1. Analysis of domestic sewage odor and garbage odor 1. The main components of municipal solid waste are: Municipal solid waste is mainly kitchen waste and fruit peels, which account for about two-thirds of the total garbage. Kitchen waste and fruit peels generally exist in the form of protein, fat and polysaccharides (starch, cellulose, etc.). During the process of fermentation, decay, and decomposition under the action of aerobic and anaerobic bacteria, a variety of odorous gas pollutants will gradually be produced. The simplified expression of the reaction process formula is: The main odor components of municipal sol...

Activated carbon uses porous physical properties to adsorb macromolecular gases and suspended particles in the air. Most of them achieve the purpose of filtering the air through forced air circulation. The filter element needs to be replaced regularly. The actual use efficiency is not high, and it cannot eradicate harmful gases.

In addition, activated carbon can only temporarily absorb a certain amount of odor. When the temperature and wind speed rise to a certain level, the adsorbed odor and odor may be freed and enter the breathing space again. The adsorption is saturated and no longer has adsorption. When the capacity is high, if the filter material is not replaced, the odor, odor, bacteria, etc. it absorbs will be released at any time and become an invisible bomb

The water washing and absorption method has poor effect on hydrogen sulfide and mercaptans; the liquid washing and absorption method has secondary pollution, and wastewater treatment is required, which is not suitable; although the direct combustion method has a good deodorization effect, it requires combustion equipment and high combustion costs; The catalytic combustion method requires precious metals as catalysts and is prone to aging, high cost, and the effect is not ideal; the one-time engineering measures of activated carbon adsorption and ozonation method are relatively simple and the deodorization effect is also ideal, but the management of activated carbon adsorption is time-consuming and laborious. The cost of carbon regeneration is high; in addition to the high cost of the ozone oxidation method, safety measures need to be strengthened
