Description

Technical Field

[0001] The utility model relates to the technical field of high-temperature waste gas treatment, in particular to a high-temperature waste gas activated carbon adsorption treatment device. Background Art

[0002] The use of activated carbon adsorption is the most common measure in waste gas treatment today. For example, activated carbon adsorption towers. Activated carbon has developed pores, a large specific surface area, and a high adsorption capacity. It can effectively remove water odor, natural and synthetic dissolved organic matter, micro-pollutants, etc.

[0003] However, when the exhaust gas temperature is too high, the performance of activated carbon will be reduced due to high-temperature oxidation and combustion, and most of the activated carbon will be burned out, and the regeneration rate will decrease. Although there are some ways to use activated carbon in conjunction with cooling equipment to reduce the exhaust gas temperature before filtering, when the exhaust gas is cooled, the water molecules in the gas condense into water droplets when they are cold, and activated carbon is prone to carbonization in a high temperature and humid environment, resulting in increased resistance and even complete failure to filter. Utility Model Content

Although there are some ways to use activated carbon in conjunction with cooling equipment to reduce the exhaust gas temperature before filtering, when the exhaust gas is cooled, the water molecules in the gas condense into water droplets when they are cold, and the activated carbon is prone to carbon particles becoming hardened in a high temperature and humid environment, the resistance increases, and it may even be completely impossible to filter.

[0013] Beneficial effects of the utility model:

[0014] 1. When the high-temperature exhaust gas passes through the middle section of the base pipe, the heat is taken away by the coolant flowing in the cooling bypass pipe to cool the high-temperature gas. At the same time, the moisture carried in the high-temperature exhaust gas condenses into water droplets on the inner wall of the base pipe when it is cooled, and slides to the water receiving edge.
