Double-gas-bubble pump diffusion absorption type thermal converter

Abstract

The invention discloses a double-gas-bubble pump diffusion absorption type thermal converter. The diffusion absorption type thermal converter comprises three parts, namely a generating and separating module, a refrigerant absorption module and a dispersing agent absorption module. The generating and separating module comprises a second generator, a second lifting pipe, a third gas-liquid separator, a second rectifying device, a first generator, a first lifting pipe, a first gas-liquid separator, a first rectifying device, a condenser and a second gas-liquid separator which are sequentially connected; the refrigerant absorption module comprises an evaporator, a first absorber, a first liquid reservoir and a first heat regenerator which are sequentially connected; and the dispersing agent absorption module comprises a second absorber, a second liquid reservoir and a second heat regenerator which are sequentially connected. In the invention, two thermally driven gas bubble pumps are adopted to realize simultaneous pumping of an absorbent solution and a refrigerant, the refrigerant and the dispersing agent are more flexible and convenient to select and use, no electric energy is consumed, and the operational reliability is improved. The thermal converter disclosed by the invention is applicable to occasions in which low and medium temperature thermal resources are rich, electric power is insufficient and a high temperature thermal resource is required, thus the thermal converter has a good application prospect.

Description

technical field [0001] The invention belongs to the field of absorption heat pumps and low-grade energy utilization, in particular to a double-bubble pump diffusion-absorption heat converter. Background technique [0002] Absorption heat pump is a kind of device that utilizes the absorption cycle of working fluid to realize the function of heat pump. It is directly driven by thermal energy. Absorption heat exchanger, also known as heating type heat pump, is a kind of absorption heat pump, which can make full use of a large amount of industrial low-temperature waste heat generated in industrial energy consumption, so that it can be reused by the production process after heating up. Since the 1970s, the worldwide energy crisis has promoted the rapid development of absorption heat exchangers. The traditional absorption heat exchangers that have been put into commercial application generally use H 2 O / LiBr is the working fluid, because the temperature of the solution pump in ...
