VOC waste gas treatment device

Abstract

A VOC waste gas treatment device is disclosed. The device includes a shell. One side surface of the shell is provided with a gas inlet. An inner-side opening of the gas inlet is provided with a filterscreen. The filter screen is fixedly connected to the inner wall of the shell through fixing bolts. The other side surface of the shell is provided with a gas outlet. Upper and lower two ends in theshell are provided with supports. A central chamber is arranged among the four supports. Bottoms of activated carbon plates are additionally provided with sealing slots, inner extending rings are additionally arranged below the sealing slots, and the sealing slots are in engagement seal with raised rings on top surfaces of the inner extending rings so that the leakproofness of mounting positions of the activated carbon plates is improved, that waste gas completely passes through the activated carbon plates is ensured and waste gas purification is more thorough. Heating rods are mounted in thecentral chamber, and, after energization, can heat waste gas substances adsorbed on the activated carbon plates to decompose the waste gas substances, and then waste gas is discharged from the gas outlet, thus effectively increasing the number of times of use of the activated carbon plates and saving the cost.

Description

technical field [0001] The invention belongs to the technical field of waste gas treatment, and in particular relates to a VOC waste gas treatment device. Background technique [0002] Industrial waste gas refers to the general term for all kinds of pollutant gases that are discharged into the air during fuel combustion and production processes in the factory area. These exhaust gases include: carbon dioxide, carbon disulfide, hydrogen sulfide, fluoride, nitrogen oxides, chlorine, hydrogen chloride, carbon monoxide, sulfuric acid (fog), lead mercury, beryllium compounds, smoke and productive dust, which will pollute the air when discharged into the atmosphere. These substances enter the human body through the respiratory tract in different ways, some directly cause harm, and some have a cumulative effect, which will seriously endanger human health. Different substances will have different effects. Industrial waste gas treatment refers to the pretreatment of waste gas produc...

Problems solved by technology

[0003] At present, the activated carbon in the purification device is generally fixed on the plate by fixing bolts, which is very inconvenient when it needs to be disassembled and replaced. In addition, it is impossible to ensure that all the exhaust gas passes through the activated carbon plate, resulting in incomplete filtration and purification. In addition, the adsorption on the activated carbon plate Waste gas is difficult to clean up and cannot be used multiple times, resulting in increased costs for users
