Abstract

The invention relates to a two-stage and multistage adsorption heat pump, belonging to the waste heat utilization technique. Wherein, it combines the middle absorbers with the middle vaporizer, to form adsorption-vaporization device; inside the adsorption-vaporization device, solution absorbs the steam of coolant from the vaporizer or superior (low-pressure) adsorption-vaporization device that processed outside the heat exchange tube; and the heated coolant from the coolant hydraulic pump flows the tube, the heat generated by using solution to absorb the steam of coolant is directly used to heat and gasify the coolant. Compared with present structure, the invention reduces the number of middle absorber and vaporizer, to make the number of adsorption-vaporization device lower 1 than the stage number, based on four basic elements that vaporizer, condenser, generator and absorber. The invention simplifies the process, improve the thermal parameter, and improve the temperature.

Description

Technical field:

[0001] The invention belongs to the field of low-temperature waste heat utilization energy-saving equipment and technology. Background technique:

[0002] Using absorption heat pump technology for waste heat utilization is an effective means, which has relatively good energy saving, environmental protection and economic benefits. In the case of relatively abundant waste heat resources, the adoption of the second type of absorption heat pump technology can bring better energy-saving benefits. For the second type of absorption heat pump, there are single-stage, two-stage and multi-stage (more than two stages). As the number of stages increases, the heating temperature increases, but the equipment is becoming more and more complicated and difficult to manufacture. and cost also increased.

[0003] In the occasions where waste heat resources are abundant, if the waste heat temperature is relatively low, or the user’s heat consumption temperature requirement is...
