Description
Technical Field
The invention relates to waste gas treatment equipment, in particular to waste gas treatment environmental protection equipment containing volatile organic compounds.
Background
At present, in the industrial production process of printing, food, plastics and the like, a large amount of waste gas containing harmful substances such as VOCs (volatile organic compounds) and the like is inevitably generated, and the main components of the VOCs are as follows: hydrocarbons, halogenated hydrocarbons, oxygen hydrocarbons and nitrogen hydrocarbons, which include: benzene series, organic chloride, freon series, organic ketone, amine, alcohol, ether, ester, acid and petroleum hydrocarbon compound. The polycyclic aromatic hydrocarbon with teratogenicity and carcinogenicity is one of the important killers for human health. The prior method for purifying VOCs in waste gas mainly comprises the following steps: UV-photolysis (UV-photolysis), adsorption, combustion, biological washing, biological filtration and biological trickling filtration, which are each associated with a respective disadvantage and advantage.
In order to meet the environmental protection requirements of modern industrial production, the purification treatment of harmful substances is required, and a UV photolysis method, a biological washing method and a biological filtration method are commonly adopted. Wherein UV photodissociation method is exactly a technique commonly used, and present UV photodissociation clarifier utilizes exhaust equipment to import foul gas to UV photodissociation clarification plant after, and the oxygen molecule in the application high energy UV ultraviolet ray light beam decomposition air produces free oxygen, active oxygen promptly, because of the unbalanced positive and negative electron that free oxygen carried so need combine with the oxygen molecule, and then produce ozone, its principle is as follows: UV + O2→O-+O＊(active oxygen) O + O2→O3(ozone), ozone has extremely strong oxidizing action to organic matter, have instant clear effect to industrial waste gas and other irritant peculiar smell, through the molecular bond of ozone pyrolysis foul gas such as ammonia, trimethylamine, hydrogen sulfide, methylthio hydrogen, carbon disulfide and styrene, sulphide, VOC class, etc., make it become harmless or low harmful compound such as low molecular compound, water and carbon dioxide, etc. that the pollutant molecule in the free state and ozone oxidize and combine, and then discharge the outdoor through the exhaust duct, achieve the goal of deodorizing and killing the bacterium. However, because the existing UV photolysis purification equipment only arranges one layer of ultraviolet lamp tube in the purification compartment, the ozone generation speed is slow, and the reaction is insufficient; because ozone is a strong oxidant with unstable chemical properties, the cracking reaction generated by UV lamp irradiation is extremely unstable, and even some processes are reversible, so that the pure UV photolysis purification effect is not ideal.
Moreover, the VOCs purification technology generally adopted in the prior art is single, the comprehensive performance is insufficient, the purification effect is not ideal when corresponding equipment is used for treating waste gas, and in addition, some equipment can also discharge waste water, so that the hidden danger of secondary pollution discharge exists.
Disclosure of Invention
