A compressed air drying adsorption device

Abstract

The invention relates to the gas drying field, and particularly relates to a compressed air drying and adsorption device comprising an inner shell, an outer shell, an adsorbent, a plurality of heat exchange pipes, air ports and heat exchange air ports; the outer shell is arranged outside the inner shell, the upper surface and the lower surface of the inner shell respectively extend to form the upper surface and the lower surface of the outer shell, and a space between the outer shell and the inner shell is an external air channel; two ends of the inner shell are each provided with the air port, and the external air channel is isolated and not communicated with the air ports; the adsorbent is located inside the inner shell, the heat exchange pipes are arranged in the adsorbent in a penetration mode, and the heat exchange air ports are arranged in the side face of the outer shell and are communicated with the external air channel; the external air channel is internally provided with a plurality of air isolation plates, and the air isolation plates, the heat exchange air ports, the external air channel and the heat exchange pipes form an unidirectional air channel retracing for a plurality of times. After adopting of the scheme, more efficient and lower-energy-consumption drying treatment on compressed air can be carried out.

Description

technical field [0001] The invention relates to the field of gas drying, in particular to a compressed air drying adsorption device. Background technique [0002] Compressed air is widely used in many industries. In order to obtain dry compressed air, it is necessary to process the compressed air produced by the air compressor to remove the moisture in the compressed air. Currently widely used drying equipment are adsorption dryers and freeze dryers. The dewatering effect of the adsorption dryer is good, but the energy consumption is relatively high, while the energy consumption of the refrigerated dryer is relatively low, but the dewatering effect is poor. [0003] The compressed air adsorption tower in the prior art is filled with a certain amount of adsorbents (molecular sieve, activated alumina, silica gel, etc.) in a container, and the compressed air containing water enters from one end of the container. The adsorbent absorbs, so as to obtain dry compressed air, which...

AI Technical Summary

Problems solved by technology

The adsorption tower of the prior art only relies on the regeneration air to carry the heat, but due to the limitation of the amount of regeneration air, the temperature of the regeneration air cannot be raised rapidly (the temperature of the regeneration air will be lowered during the heatless regeneration), and the Regeneration air absorbs less water vapor, which leads to an increase in the amount of regeneration air and energy consumption
