Problems solved by technology

However, when the desorption is completed, the temperature of the activated carbon is relatively high. At this time, it does not have the ability to adsorb volatile organic compounds. The adsorption efficiency of the waste gas into the activated carbon is very low, and there is a risk that the waste gas emission will not meet the standard.

Abstract

The invention discloses an organic waste gas treatment system. The organic waste gas treatment system comprises at least two activated carbon adsorption boxes connected in parallel, first gas inlet pipelines are arranged at the bottoms of the activated carbon adsorption boxes, valves A are arranged on the first gas inlet pipelines, adsorption fans are connected to the tops of the activated carbonadsorption boxes through purification pipelines, and valves B are arranged on the purification pipelines. The top of each activated carbon adsorption box is connected with catalytic combustion equipment through a desorption pipeline, a valve C is arranged on each desorption pipeline, catalytic combustion equipment is connected with a desorption fan, the desorption fan is connected to the bottoms of the activated carbon adsorption boxes through hot air pipelines, a valve D is arranged on each hot air pipeline, and an air supplementing pipeline is arranged between each valve D and the desorptionfan; a second air inlet pipeline is further arranged at the top of each activated carbon adsorption box, a valve E is arranged on each second air inlet pipeline, and the negative pressure of the second air inlet pipeline is higher than that of the first air inlet pipeline. The problem that waste gas emission does not reach the standard due to the fact that adsorption efficiency of activated carbon which is just desorbed is low is solved.

Description

technical field [0001] The invention relates to the technical field of water treatment, in particular to an organic waste gas treatment system. Background technique [0002] The existing volatile organic waste gas (VOCs) treatment method is mainly activated carbon adsorption. After the adsorption is saturated, high-temperature gas at 80-110°C is used to desorb the absorbed organic waste gas. This process can improve the service life of activated carbon and reduce the user's cost. It is one of the most commonly used treatment processes for organic waste gas to realize the recycling and reuse of activated carbon. However, when the desorption is completed, the temperature of the activated carbon is relatively high. At this time, it does not have the ability to adsorb volatile organic compounds. The adsorption efficiency of exhaust gas into the activated carbon is very low, and there is a risk that the exhaust gas emission will not meet the standard. Contents of the invention ...
