Adsorption bed structure

Abstract

The invention provides an adsorption bed structure. The adsorption bed structure comprises an adsorption bed housing and at least one unit tube; an inlet and an outlet are formed in the adsorption bed housing to allow an external medium to go in and out; the unit tube is arranged within the adsorption bed housing; the unit tube comprises a metal tube and a metal mesh tube which sleeve each other, an adsorbent filled between the metal tube and the metal mesh tube, and a front end cover and a rear end cover which are arranged at two end portions of the unit tube to seal the adsorbent; and the external medium circulates on a surface, back on to the adsorbent, of the metal tube. The adsorption bed structure provided by the present invention may enable the adsorbent to have relatively high packing density, and the adsorption bed to have a small size and packing volume.

Description

technical field [0001] The invention relates to the technical field of adsorption refrigeration, in particular to the structure of an adsorption bed. Background technique [0002] Adsorption refrigeration, as a green and environmentally friendly technology that can be driven by low-grade heat energy (such as engine exhaust, geothermal energy, etc.), has attracted more and more attention from researchers. Adsorption refrigeration system is mainly composed of adsorption bed, evaporator and condenser. Adsorption refrigeration generally includes two processes: (1) cooling adsorption process, which uses cooling water or air to cool the adsorption bed, so that the adsorbent in the adsorption bed Adsorb the refrigerant in the evaporator, and the refrigerant evaporates in the evaporator to generate cold energy; (2) Heating and desorption process, which uses low-grade heat energy to regenerate the adsorbent saturated with adsorption, that is, to separate the refrigerant from the adso...

AI Technical Summary

Problems solved by technology

If this kind of adsorption bed is used to exchange heat with flue gas / air, the effect of flue gas / air flow inside the finned tube will be very bad

At the same time, the packing density of this kind of adsorption bed is also relatively small, and because of the fins, the overall adsorption bed is also heavier.
