An adsorption runner and transcritical heat pump cycle compound gas purification device and its application

Abstract

The invention discloses an adsorption rotary wheel and transcritical heat pump cycle combined gas purification device. The adsorption rotary wheel and transcritical heat pump cycle combined gas purification device comprises an adsorption rotary wheel, an overlapped heat pump comprising two single-stage transcritical cycles and a work region air cycle loop. Cold air at a cold end of the overlapped heat pump is introduced into the work region air cycle loop so as to realize air ventilation, temperature adjustment and gathering of gases of VOC (Volatile Organic Compound)s of a work region; output air of the work region air cycle loop is introduced into a low-temperature adsorption region of the adsorption rotary wheel to realize adsorption of the gases of the VOCs; hot air at a hot end of the overlapped heat pump is introduced into a high-temperature desorption region of the adsorption rotary wheel to realize desorption of the gases of the VOCs in an adsorption material; and fresh air is introduced into a cooling and regenerating region of the adsorption rotary wheel to realize cooling on the adsorption material. The cooling capacity and the heating capacity provided by the cold end and the hot end of a heat pump cycle system of the device can both be well utilized, the energy saving effect is obvious compared with traditional electric heating, and the purposes of energy conservation and emission reduction are realized.

Description

technical field [0001] The invention relates to the field of gas purification, in particular to a composite gas purification device and application of an adsorption runner and a transcritical heat pump cycle. Background technique [0002] At present, in industries such as automobile spraying, a large amount of organic waste gas is usually produced. If these organic waste gases are discharged directly, they will not only cause serious pollution to the environment, but also directly endanger human life and health. Industrial treatment of organic waste gas generally adopts combustion treatment technology, absorption technology, biological treatment technology, membrane separation technology and adsorption technology. [0003] Combustion treatment technology is divided into direct combustion and catalytic combustion. Direct combustion directly passes VOCs gas into the combustion chamber for high-temperature combustion, which will cause secondary pollution and open flames. Most c...
