Description

Pipeline formula photodissociation catalytic oxidation clarifier

Technical Field

The utility model relates to a waste gas purification device, specific pipeline formula photodissociation catalytic oxidation clarifier that utilizes UV ultraviolet ray and titanium dioxide photocatalyst cooperation to accomplish waste gas purification that says so.

Background

With the requirement of the country for environmental governance, certain requirements are imposed on the production and living waste gases of various industries, and a lot of waste gases are not allowed to be directly discharged into the atmosphere without being treated.

At present, the common methods for treating organic waste gas include adsorption method, absorption method, catalytic combustion method, biological treatment method, etc. Activated carbon adsorption is the immobilization of pollutants from the gas phase to itself and does not address elimination. When a plurality of gaseous pollutants coexist, the adsorption capacity of the activated carbon is reduced. Meanwhile, the activated carbon with saturated adsorption is abandoned and directly burnt or buried, so that resource waste is caused. Secondly, the regeneration is recycled, but the regeneration has some problems, such as a certain reduction of adsorption capacity after regeneration, excessive loss of a correction part in the regeneration process, secondary pollution of regeneration tail gas and the like.

The absorption method is physical transfer or chemical transfer of pollutants from gas phase to liquid phase, the gaseous pollutant liquid phase spraying is better for high-concentration organic waste gas or organic waste gas with large air quantity and low concentration, and the treatment efficiency for organic waste gas with low concentration and low air quantity needs to be further improved.

The catalytic combustion method is rigorous for selecting certain gas pollutant catalysts, and high temperature, high altitude and high steam partial pressure are required, so that the selected catalysts have high activity, high thermal stability, high hydrothermal stability and certain poisoning resistance. The method has strict requirements on process conditions, does not allow the waste gas to contain dust particles and fog drops which influence the service life and the treatment efficiency of the catalyst, and does not allow substances poisoned by the catalyst to prevent the catalyst from being poisoned.

The biological treatment method has selectivity, microorganisms have slow degradation speed to organic pollutants such as Phthalate Substances (PAEs), benzene substances and the like, mainly because molecules of polymers and compounds can resist biological degradation, and enzymes necessary for the microorganisms cannot approach and destroy sensitive reactions in the molecules of the compounds, so that the application of the biological method in the aspect of treating the gaseous substances is limited.

The treatment modes all have various obvious defects and cannot well meet the requirements of actual production and use.

In conclusion, the industry is in need of a waste gas purification device with low use cost, good effect and strong sustainability.
