Problems solved by technology

[0003] According to the form of pollutants, chemical waste gas can be divided into particulate pollutants and gaseous pollutants. Due to the high content of toxic gases in chemical waste gas and the unclear composition, there is no clear method for subsequent treatment of waste gas. Therefore, at present, when treating exhaust gas particles, most of the particulate pollutants in the exhaust gas will be adsorbed by activated carbon. In the existing exhaust gas treatment devices, the validity period of activated carbon is 3 to 6 months, usually three months. Replace the activated carbon once, but when there are many solid particles in the exhaust gas, the activated carbon will be saturated usually three months ago. If it is not replaced in time, the particulate matter in the exhaust gas will exceed the standard, resulting in troublesome follow-up treatment, or when there are few solid particles in the exhaust gas , after three months, the activated carbon can still continue to adsorb but is replaced, resulting in an increase in the cost of activated carbon replacement. Therefore, we propose a waste gas treatment device for the production of chemical raw materials

Abstract

The invention discloses a waste gas treatment device for chemical raw material production. The waste gas treatment device comprises a treatment cylinder for containing activated carbon, a sleeve cover and a stirring assembly, a filter screen plate is fixed to the inner wall of the bottom of the treatment cylinder, the sleeve cover sleeves the bottom of the treatment cylinder, the bottom end of the sleeve cover is connected with a connecting piece in butt joint with a waste gas pipeline, the stirring assembly used for stirring activated carbon in the treatment cylinder to improve the adsorption effect is installed in the treatment cylinder and connected with the sleeve cover, and a detection mechanism used for detecting the saturation degree of activated carbon is installed at the top end of the sleeve cover and the top end of the stirring assembly. According to the waste gas treatment device disclosed by the invention, the stirring assembly and the detection mechanism are additionally arranged on the treatment cylinder, so while waste gas is treated, activated carbon can be stirred, contact of the activated carbon with waste gas is improved, and the adsorption effect of the activated carbon is better; and meanwhile, two detection mechanisms are matched to detect waste gas inlet pressure and waste gas exhaust pressure, the saturation condition of the activated carbon in the treatment cylinder can be known through comparison, and follow-up replacement time of the activated carbon is more accurately controlled.

Description

technical field [0001] The invention relates to the technical field of waste gas treatment, in particular to a waste gas treatment device for chemical raw material production. Background technique [0002] Chemical waste gas refers to the toxic and harmful gas discharged from chemical plants in chemical production. Chemical waste gas often contains many types of pollutants, complex physical and chemical properties, and different toxicity. It seriously pollutes the environment and affects human health. Different chemical production The chemical waste gas composition produced by the industry varies greatly. [0003] According to the form of pollutants, chemical waste gas can be divided into particulate pollutants and gaseous pollutants. Due to the high content of toxic gases in chemical waste gas and the unclear composition, there is no clear method for subsequent treatment of waste gas. Therefore, at present, when treating exhaust gas particles, most of the particulate pollu...
