Embodiment Construction

[0013] The exhaust gas enters the pretreatment chamber 2 through the intake pipe 1, which is connected to the filter layer 8, the solid-liquid separator 4, and the water pump 6. When the exhaust gas enters, the water pump 6 draws water from the solid-liquid separator 4 and sprays it into the pretreatment chamber by the sprayer 3. In the processing chamber 2, the water mist can take out most of the solids and dust in the exhaust gas, and then return to the solid-liquid separator 4. The bottom of the solid-liquid separator 4 is a cone structure. When the water with solids and dust flows in Among them, moving along the surface of the vertebral body, the mixed fluid is subjected to shearing force, centrifugal force and gravity, and the solid matter is naturally deposited and separated from the water. The filter layer 8 can also filter the solid matter and dust in the gas; the gas is buoyant Under the action of the filter layer 8, it enters the packing layer 9. This layer is filled w...

Abstract

The invention relates to an ozone coordinated photocatalytic waste gas purification device. The device makes use of the principles of ozone oxidation reaction and photocatalytic reaction, can quickly and efficiently treat waste gas, the whole process only consumes electric energy, does not generate no secondary pollution, is energy-efficient, and can be widely used for purification of various waste gas.

Description

Technical field [0001] The invention relates to a purification device, which is mainly used for the purification of exhaust gas and belongs to the field of environmental protection and pollution control. Background technique [0002] Waste gas purification mainly refers to the treatment of industrial waste gas generated in industrial sites such as dust particles, smoke and dust, odorous gases, and toxic and harmful gases. At present, the methods for exhaust gas treatment mainly include water absorption method, aeration activated sludge deodorization method, multi-media catalytic oxidation process and dilution diffusion method. These methods have secondary pollution, low purification efficiency, and poor impact load resistance. Reagents need to be added, which is greatly affected by the environment. Summary of the invention [0003] The invention overcomes the defects of the existing treatment method and develops an ozone synergistic photocatalytic exhaust gas purification device ...
