Organic waste gas concentrating, absorbing and catalyzing combustion device

Abstract

The invention relates to an organic waste gas concentrating, absorbing and catalyzing combustion device, comprising a waste gas inlet for inputting waste gas, a pure gas outlet for outputting pure gas, at least one absorption tank filled with an active carbon absorption layer, a catalytic combustion device and a control device, wherein all deices are connected through pipelines; the pipelines are provided with valves for controlling connection or disconnection of the pipelines; the absorption tank is connected with a gas supplementing passage; the combustion device has an absorption work status and a desorption work status; when the combustion device is at the absorption work status, the waste gas inlet, the absorption tank and the pure gas outlet form a passage; and when the combustion device is in the desorption work status, the gas supplementing passage, the absorption tank, the catalytic combustion device and the pure gas outlet form a passage. The organic waste gas concentrating, absorbing and catalyzing combustion device disclosed by the invention can be used for absorbing organic waste gas, and can be used for desorbing the active carbon layer of the absorption tank and then catalytically combusting an organic solvent, so that the exhausted gases are clean gases. The device has a simple structure and good processing effect and can be applied widely.

Description

technical field [0001] The invention relates to the field of waste gas treatment, in particular to an organic waste gas concentration adsorption catalytic combustion device. Background technique [0002] There are many types of organic waste gas, complex composition, and various concentrations, so its treatment is more difficult. [0003] At present, the purification and treatment processes adopted by organic waste gas purification devices include catalytic combustion method, activated carbon adsorption method, condensation method, absorption method and plasma oxidation method, etc., which solve the pollution of organic waste gas to the environment to a certain extent, but the above purification and treatment devices are also There are many problems. [0004] The existing activated carbon adsorption method first absorbs the organic solvent in the organic waste gas, and then discharges the net gas. When the activated carbon reaches saturation, it is desorbed to collect the o...

Problems solved by technology

Generally speaking, the two treatment processes need to be completed by two devices. Therefore, for the requirement that all the processes of adsorption and desorption should be completed in one, the cost of the two devices is not only high, but also consumes man-hours, which is inconvenient.
