Problems solved by technology

[0005] As for the adsorption and desorption pilot plant, it is currently used more for packed bed devices. In the test, the waste gas of a certain concentration is flowed into the fixed bed for adsorption and desorption, and then the concentration is detected by the detection instrument. However, in the tube type adsorption and desorption The adsorption and desorption test device on the material has not yet appeared in the patent literature

Abstract

The invention relates to a pipe type adsorption and desorption-catalytic combustion pilot trial testing device. The pipe type adsorption and desorption-catalytic combustion pilot trial testing devicecomprises a shell, wherein the shell is internally provided with a gas inlet device, an adsorption and desorption pipe device and a catalytic combustion device; the gas inlet device is connected withthe catalytic combustion device through the adsorption and desorption pipe device; the adsorption and desorption pipe device comprises a gas heater, a first draught fan, a high-temperature steam pipeline, a first adsorption and desorption device and a second adsorption and desorption device; the first adsorption and desorption device and the second adsorption and desorption device are connected with the high-temperature steam pipeline; the first draught fan is connected with the high-temperature steam pipeline through the gas heater; VOCs (Volatile Organic Compounds) gas is adsorbed and desorbed in the adsorption and desorption pipe device and adsorbed clean air is discharged; adsorbed waste gas enters the catalytic combustion device, and purging steam heated at high temperature is used for carrying out physical desorption and concentration on VOC components in a catalyst; concentrated gas enters a heat exchanger and a catalytic combustor to react and reaction heat is released, so thatthe emission of final non-toxic carbon dioxide and water steam is finished.

Description

technical field [0001] The invention relates to a tube-type adsorption-desorption-catalytic combustion pilot test device, which belongs to the field of waste gas treatment equipment. Background technique [0002] Among the VOCs exhaust gas treatment technologies, there are direct condensation technology, combustion technology method (regenerative catalytic combustion, direct combustion method), absorption and desorption-condensation recovery method. But these methods have advantages and disadvantages. But at present, direct combustion and direct condensation methods are mainly used in environments with high concentrations of VOCs, and are especially suitable for gas components whose condensation temperature is close to that of room temperature. Adsorption-desorption-condensation technology, adsorption-desorption-catalytic combustion technology is mainly used in the gas environment with low concentration of VOCs (generally 15-200ppm), but the adsorption and desorption proces...
