Problems solved by technology

[0006] (3) The ratio of the total heat capacity of the materials used in the production of the adsorption bed to the total heat capacity of the adsorbent filled in the bed (heat capacity ratio) should be appropriate. The more heat consumed, the higher the energy consumption of the system and affect the performance of the system
In the mass transfer channel, cylindrical steel wires are used to support adjacent units to leave gaps, resulting in poor pressure bearing capacity and poor reliability of the entire adsorption bed; multiple steel wires need to be welded in two porous plates, which not only increases the metal consumables, but also increases the adsorption capacity. The total heat capacity of the bed, and the high temperature during the soldering process will cause the packaged part of the adsorbent to fail

Abstract

The invention discloses a mass transfer enhancing type modular adsorption bed. The mass transfer enhancing type modular adsorption bed comprises a plurality of coil pipe units which are sequentially and horizontally arranged in a stacked mode with one above another. Fin maintaining strips of every two adjacent coil pipe units are fixedly connected through bolts. Side plates at the four corners of the fin maintaining strips of all the coil pipe units are fixedly connected with fixed supporting rods through bolts, and the fixed supporting rods are arranged in the vertical direction. Inlets of heat exchange pipes of all the coil pipe units are sequentially connected with a fluid inlet straight pipe, a right-angled elbow pipe and a fluid distribution header pipe, and outlets of the heat exchange pipes of all the coil pipe units are sequentially connected with a fluid outlet straight pipe, a right-angled elbow pipe and a liquid converging heater pipe. Upper fixing channel steel is fixed to side porous plates and the fin maintaining strips of the coil pipe unit at the top, and lower fixing channel steel is fixed to side porous plates and the fin maintaining strips of the coil pipe unit at the bottom, and the lower fixing channel steel is fixedly supported on two adsorption bed bases. According to the mass transfer enhancing type modular adsorption bed, the coil pipe units which are independently machined can be dismounted or additionally mounted easily and conveniently, and modular production is achieved.

Description

technical field [0001] The invention relates to an adsorption bed in an adsorption gas separation process, in particular to an adsorption bed capable of modular production and capable of enhancing heat and mass transfer. Background technique [0002] In an adsorption refrigeration system, the heat exchanger components include the adsorption bed, condenser, and evaporator. Among them, the heat transfer performance of the adsorption bed directly determines the design parameters of the heat transfer performance of the evaporator and condenser, which greatly affects the performance of the system. The design of the heat exchanger should first meet the basic heat and mass transfer requirements, and secondly, it should be as compact and efficient as possible, and the arrangement of the adsorption bed should be more suitable for the flow of the working fluid. At present, the factors affecting the large-scale promotion of adsorption refrigeration systems mainly include the following...
