Separated UV photolysis waste gas purifier

Abstract

The invention relates to the technical field of environmental protection equipment, and discloses a separated UV photolysis waste gas purifier, which comprises a pretreatment box. A left inner cavityand a right inner cavity of the pretreatment box are divided into a pyrolysis cavity and an oxygen supply cavity; photolysis devices are arranged in inner cavities of the pyrolysis cavity and the oxygen supply cavity respectively; a reaction box is arranged under the pretreatment box; a deep treatment box is arranged under the reaction box; the reaction box is communicated with the inner cavity ofthe deep treatment box; and a tail gas exhaust pipe is arranged at the top of one side of the deep treatment box. The inner cavity of the pretreatment box is divided into the pyrolysis cavity and theoxygen supply cavity, and the photolysis devices are arranged in the pyrolysis cavity and the oxygen supply cavity respectively; high-molecular organic gas is subjected to pyrolysis at the photolysisdevice in the pyrolysis cavity, then, ozone molecules are generated at the photolysis device in the oxygen supply cavity, and the low-molecular organic gas obtained after pyrolysis and the ozone molecules are mixed and then oxidized through a flow guide pipe, so that on one hand, the low-molecular organic gas obtained after pyrolysis is easier to oxidize, and on the other hand, the generated ozone molecules are fully utilized.

Description

technical field [0001] The invention relates to the technical field of environmental protection equipment, in particular to a separate UV photolysis waste gas purifier. Background technique [0002] High-energy UV ultraviolet light beams can crack the molecular chain structure in organic gases and degrade them into low-molecular compounds. At the same time, UV ultraviolet light beams can decompose oxygen molecules in the air to generate free oxygen. Combined with oxygen molecules, ozone is produced. Ozone has strong oxidizing properties, and can further oxidize organic gases and their low-molecular compounds into low-polluting compounds such as carbon dioxide and water, thereby achieving the effect of purifying exhaust gas. [0003] In the prior art, after the exhaust gas is filtered, it is directly passed into the high-energy UV ultraviolet beam box, and the purification reaction is carried out in the isolation box. After the exhaust gas contacts with the air, its temperatu...
