Problems solved by technology

As the core component of traditional adsorption refrigeration, the adsorption bed is usually composed of two concentric circular tubes (granular activated carbon and methanol are placed between the tubes), which can increase the desorption temperature of the adsorption bed in a short irradiation time, but it is not conducive to cooling the adsorption process. heat dissipation

Embodiment 1

[0030] The adsorption refrigeration system performance simulation test device was built, and the adsorption capacity of granular activated carbon 3 prepared from sample carbon material to methanol was tested by gravimetric method.

[0031] Adsorption is actually a mass transfer process. The adsorbate first contacts the surface of the adsorbent, and then diffuses into the adsorbent to gradually reach the adsorption equilibrium state. The equilibrium adsorption capacity of the system is related to factors such as the adsorption temperature, pressure, and the properties of the adsorbent and adsorbate. The size of the adsorption capacity of the adsorbent is usually expressed by the adsorption amount when the reaction adsorption reaches the equilibrium state. In this experiment, the granular activated carbon 3 prepared by the sample carbon material was used as the adsorbent, and the adsorption reaction occurred in contact with the adsorbate (methanol) vapor at a certain temperature...

Abstract

A shell tube type adsorption bed with puncture membrane type adsorption mass tubes comprises a shell, and further comprises a metal mesh, activated carbon, heat conduction tubes and the puncture membrane type tubes, all of which are arranged in the shell. The shell is provided with a heat conduction liquid inlet and a heat conduction liquid outlet which are communicated with the two ends of each heat conduction tube respectively. The shell is provided with an air outlet hole, and the metal mesh is arranged on the inner side face of the shell. The diameter of holes in the metal mesh is smaller than the grain diameter of the activated carbon. The heat conduction tubes and the puncture membrane type tubes are arranged in parallel and alternately arranged. The activated carbon is arranged in gaps between the heat conduction tubes and the puncture membrane type tubes. The puncture membrane type tubes are made of membranes and comprise main mass transfer tubes and bypass branch tubes vertically arranged on the main mass transfer tubes. The main mass transfer tubes are provided with mass transfer holes, and the diameter of the mass transfer holes is smaller than the grain diameter of the activated carbon.

Description

technical field [0001] The invention relates to a solid adsorption refrigeration device, in particular to a shell-and-tube adsorption bed with perforated membrane-type adsorbent tubes. Background technique [0002] Solid adsorption refrigerators are often used as vacuum pre-cooling of fruits and vegetables or cold sources for storage cold storage. The adsorption refrigeration system does not use chlorofluorocarbon refrigerants CFC and HCFC, and is an environmentally friendly refrigeration method. The adsorption refrigeration system can effectively use solar energy, industrial waste heat and other low-grade heat energy above 50°C as the driving energy of the system. It has simple structure and easy operation; no moving parts, good vibration resistance; Advantages of low cost. [0003] The solid adsorption refrigerator is mainly composed of adsorption bed, condenser, evaporator, liquid receiver, valves and control elements (one-way check valve, throttle valve, etc.) and other...
