Problems solved by technology

However, these existing ultraviolet light degradation air purifiers can only make the exhaust gas photodegrade by ultraviolet light irradiation when the exhaust gas flows through the side of the ultraviolet lamp tube, which is limited by the shape of the inner chamber of the purifier, and part of the exhaust gas is far away from the ultraviolet lamp. The tube is far away, and the range of ultraviolet radiation is not strong. Some exhaust gas may flow away before decomposing in the future. The photolysis efficiency is low, and the removal effect on odorous or toxic and harmful gases is poor.

Embodiment Construction

[0022] like Figures 1 to 3 As shown, this embodiment provides an ultraviolet photooxidation device, which is suitable for treating domestic waste gas, agricultural waste gas, industrial waste gas, etc., and is specifically suitable for removing volatile organic compounds VOC, hydrogen sulfide, Ammonia, mercaptans, bacteria and other toxic, harmful and odorous substances. The ultraviolet photooxidation device of this embodiment can be used alone, and can also be used in combination with a filter-type filter. For example, the waste gas is first filtered through a filter-type filter to remove particulate matter, liquid droplets and some toxic, harmful and odorous gases in the waste gas. Then go through the ultraviolet photooxidation device of this embodiment for further deodorization and purification treatment.

[0023] The ultraviolet photooxidation device of this embodiment includes a plurality of parallel ultraviolet photooxidation units 10 , and each ultraviolet photooxidat...

Abstract

The invention relates to an ultraviolet photooxidation device which comprises a plurality of parallel ultraviolet photooxidation units, and each ultraviolet photooxidation unit comprises an ultraviolet lamp tube and a cylindrical filter screen arranged around the ultraviolet lamp tube; one of the inner side and the outer side of the cylindrical filter screen is communicated with the air inlet, and the other one is communicated with the air outlet. The ultraviolet photooxidation device can improve the photolysis efficiency and improve the purification effect on waste gas.

Description

technical field [0001] The invention relates to the technical field of air purification, in particular to an ultraviolet light oxidation device. Background technique [0002] Waste gas containing organic or inorganic substances is often produced in daily life or in agricultural and industrial production processes. For example, the waste gas may contain volatile organic compounds VOC, hydrogen sulfide, ammonia, mercaptans, bacteria and other pollutants. Specific types of chemical substances have peculiar smell, these exhaust gases will cause environmental pollution, and long-term inhalation will endanger human health. The existing filter-type air purification device can only remove some harmful substances in the exhaust gas, such as solid particles, suspended liquid droplets and certain harmful gases, etc., and cannot remove volatile organic compounds, bacteria and other substances well. The air still has peculiar smell or is harmful to the environment and human body. [00...
