Problems solved by technology
[0003] In order to avoid the occurrence and deterioration of the above situation, various waste gas purification enterprises in the country have carried out research and manufacture of related equipment, aiming to use the produced equipment to efficiently treat a large amount of odorous and harmful gases generated in industrial production, so as to achieve the national waste gas External emission standards; in view of the problems existing in different industrial enterprises, many enterprises have developed their own exhaust gas purification equipment, and many equipment use UV photocatalytic oxidation technology to purify odorous gases, but this type of traditional purification equipment still has deodorization problems. Thoroughness, low processing efficiency, poor adaptability, large equipment volume, high operating costs, etc.

The invention discloses equipment for treating VOCs with a photocatalytic material supported ACF. The equipment comprises a photocatalysis reactor and a drought system, wherein an HEPA efficient filtering net is vertically arranged inside the photocatalysis reactor to partition a cavity into a waste gas pretreatment chamber and a photocatalysis reaction chamber; a gas inlet is formed in the frontend of the waste gas pretreatment chamber; a plurality of air guide plates are uniformly arranged between the gas inlet and the HEPA efficient filtering net; a plurality groups of partition plates arearranged at intervals inside the photocatalysis reaction chamber in a horizontal gas inlet direction; each group of the partition plates comprises four horizontally arranged partition plates; the cavity is partitioned into five areas from top to bottom by each group of the partition plates; Co-TiO2 / ACF photocatalysis reaction cavities and UV lamp tube zones are alternatively arranged in the fiveareas; a gas outlet is formed in the rear end of the photocatalysis reaction chamber; the gas outlet is connected with the drought system. The equipment disclosed by the invention is simple in structure, low in operation cost, good in adaptability and small in floor space, is capable of treating VOCs, and is high in purification efficiency and free of secondary pollution.
Description
technical field [0001] The invention relates to the technical field of exhaust gas treatment, in particular to a device for treating VOCs loaded with ACF on a photocatalytic material. Background technique [0002] In recent decades, with the rapid development of my country's industrial enterprises and rapid economic growth, environmental problems have become more and more serious, and the problem of air pollution has become more and more prominent. Volatile organic compounds (VOCs) are a very important type of air pollutants . The World Health Organization (WHO) defines volatile organic compounds as: as organic compounds, under standard atmospheric pressure, the general term for organic compounds with a melting point lower than room temperature and a boiling point lower than 50-260 °C. There are many types of VOCs and a wide range of sources. Petroleum industry, chemical pharmaceuticals, home decoration, experimental reagents, and automobile exhaust will produce VOCs exhaust...
