Description

A non-contact odor and odor gas treatment device

technical field

The utility model relates to the field of waste gas treatment, in particular to a non-contact type malodorous odor gas treatment device.

Background technique

With the improvement of residents' living standards and the change of life concepts, the requirements for the environment are getting higher and higher, and odor pollution has increasingly become a serious social and environmental problem. Odor pollution mainly comes from factories, and the composition of odor gas is complex and difficult to monitor. Common malodorous gases can be divided into five categories: nitrogen-containing compounds, sulfur-containing compounds, halogenated hydrocarbons, hydrocarbons, and oxygen-containing organics. Conventional malodorous gas treatment methods include scrubbing absorption method, biological treatment, photocatalytic oxidation, incineration, activated carbon adsorption, plasma method, etc.

(1) The scrubbing absorption method mainly uses water or solution to dissolve malodorous gases and react with odor molecules, but many malodorous gases are insoluble in water or solutions, resulting in poor deodorization effect and high equipment maintenance costs, resulting in waste water or solid waste, etc. Secondary pollution.

(2) The biological treatment method mainly converts the odorous gas through the physiological and metabolic activities of microorganisms. Malodorous gases act as nutrients for microorganisms. The disadvantage is that the microorganisms need to be cultured first, and the temperature has a relatively large influence on the microorganisms and occupies a large area.

(3) Photocatalytic oxidation is to activate the catalyst to generate electron-hole pairs through ultraviolet irradiation of a specific wavelength, and then the catalyst reacts with water and oxygen molecules to generate hydroxyl radicals, and then decomposes the malodorous gas to achieve the purpose of deodorization. However, in photocatalytic oxidation, the catalyst is easily poisoned and the catalyst needs to be replaced frequently, resulting in secondary pollution.

(4) Incineration is when the odorous gas is fully mixed with the fuel gas to achieve complete combustion. However, it is suitable for processing combustible gas with high concentration and small gas volume. However, the equipment cost is high, the equipment is easily corroded and the loss is large, the floor space is large, the fuel gas consumption is large, and the operation and maintenance cost is high.

(5) Activated carbon adsorption is to use the adsorption function of activated carbon to transfer malodorous gas from the gas phase to the solid phase to achieve the purpose of deodorization. The disadvantage is that the consumption of the adsorbent is large, and the regeneration is difficult.

(6) The plasma method uses an ion reaction introduction device to generate ions in the main reactor. During the dielectric barrier discharge process, particles rich in extremely high chemical activity, such as electrons, ions, free radicals and excited molecules, are generated inside the plasma. The pollutants in the exhaust gas react with these active groups with high energy, and are finally converted into substances such as CO ₂ and H ₂ O, so as to achieve the purpose of purifying the exhaust gas. However, when dealing with flammable and explosive gases, there is a risk of explosion, the discharge field has a small scope, and the purification efficiency is low in the case of high flow rate and large air volume.
