Problems solved by technology

This thin-layer structure greatly reduces the thermal resistance of the adsorption bed, but because the gap between the fiber bundles controls the mass transfer rate, the mass transfer resistance will rise as the main factor affecting the adsorption rate

Embodiment Construction

[0020] In order to further describe the structural features and functions of the present invention, the following description is given in conjunction with the accompanying drawings:

[0021] See figure 1 , The core end plate 4, the metal U-shaped tube 5, the electrostatic input end 6, the aluminum fin 7 and the attachments 8 on the fin constitute the adsorbent bed core 1. The core 1 is made of polytetrafluoroethylene or fluororubber material and the shell The body 2 and the head 3 are electrostatically insulated, and the input or discharge of static charge to the core 1 can only be done through the electrostatic input terminal 6. The polytetrafluoroethylene or fluororubber material includes an electrostatic insulating sealing ring 9 and an electrostatic insulating plate 10. The electrostatic insulating sealing ring 9 is placed between the shell 2 and the core end plate 4, on the lower surface of the core end plate 4, and the shell The open periphery of the body 2 is fixedly conne...

Abstract

A high-power-density activated carbon fibre adsorption bed controlled and intensified by electrostatic charges and used for the solid-adsorptive refrigerating system is composed of an adsorption core, a casing and a closure head. Said core has the electrostatic input for the controllable charging and discharging of electrostatic charges. When said adsorption bed is in adsorption state, the positive charges are charged onto the activated carbon fibre cloth for intensifying adsorption effect. When it is in desorption state, said positive charges are discharged for lowering the desorption temp.

Description

Technical field [0001] The invention relates to a high-power density adsorption bed that realizes control enhancement by inputting and releasing static charge, and particularly refers to a high-efficiency adsorption bed used in a solid adsorption refrigeration system. Background technique [0002] The adsorption bed in the solid adsorption refrigeration system is operated in a periodic heating / cooling mode. The heat and mass transfer rate of the refrigerant vapor in the pores of the adsorbent determines the specific power output of the refrigeration system. The conventional activated carbon particle adsorption bed has low power density and large volume due to the large heat transfer resistance, which affects its practicability. The micropores of activated carbon fiber (ACF) are distributed on the surface of the fiber, the pore size distribution is uniform, the adsorption rate is fast, and the adsorption capacity is large. It is an excellent solid adsorbent. In order to overcome t...
