Diffusion absorption type thermal converter without moving parts

Abstract

The invention discloses a diffusion absorption type thermal converter without moving parts. 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 generator, a lifting pipe, a first gas-liquid separator, a 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, a first heat regenerator and a first regulating valve which are sequentially connected; and the dispersing agent absorption module comprises a second absorber, a second liquid reservoir, a second heat regenerator and a second regulating valve which are sequentially connected. In the invention, a thermally driven gas bubble pump is adopted to realize simultaneous pumping of an absorbent solution and a refrigerant liquid, no electric energy is consumed, and the operational reliability is improved. The thermal converter disclosed by the invention is especially 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 pump and low-grade energy utilization, in particular to a diffusion-absorption heat converter without moving parts. Background technique [0002] Since the 1970s, the worldwide energy crisis has promoted the rapid development of absorption heat pumps. Absorption heat exchanger, also known as heating-type heat pump, can make full use of a large amount of industrial low-temperature waste heat generated in petrochemical, metallurgy, power and other industrial energy, so that it can be directly used by the production process after the grade is raised. Traditional absorption heat exchangers that have been put into commercial use are mainly based on H 2 O / LiBr is the working fluid, but due to the high operating temperature of the mechanical solution pump, H 2 The strong corrosiveness of O / LiBr solution limits its wide application. [0003] Diffusion-absorption refrigerator achieves the cooling effect b...
