Abstract

The invention relates to a regeneration treatment method for a lithium bromide solution in an absorption refrigerator. The regeneration treatment method comprises the steps: (1) raw material collection; (2) ingredient preparation; (3) artificial flocculation system establishment; (4) aging aeration; (5) pH value regulation; (6) reactor high temperature concentration; (7) cooling; (8) fine tuning; (9) clay pot circulating filtration; and (10) packaging and storage. Different sustained release preparations in the lithium bromide solution and various metal ions affecting the effect of the refrigerator can be effectively removed, meanwhile, the content of various corrosive anions is greatly reduced, various impurities can be effectively removed, the quality of a waste lithium bromide solution is effectively improved, so that the recycle of the waste lithium bromide solution is realized; and various harmful substances in the lithium bromide solution can be simultaneously removed with high efficiency and low cost, supervising the process by special personnel at any time is not needed, and the automatic starting or stopping can be realized by time or temperature setting, so that the labor efficiency is increased.

Description

technical field [0001] The invention relates to the technical field of regeneration treatment of lithium bromide solution in refrigerators, in particular to a method for regeneration treatment of lithium bromide solution in absorption refrigerators. Background technique [0002] Lithium bromide solution is an important working medium required by lithium bromide refrigerators in refrigeration work, and plays a very important role in absorption refrigerators and absorption heat pumps that are widely used in the world. The lithium bromide absorption refrigerator uses water as the refrigerant and lithium bromide solution as the absorbent, and is used in the central air-conditioning system to produce low-temperature water above 0°C. The absorption heat pump machine is the reverse cycle of its refrigeration equipment, which can convert low-grade heat sources into high-grade heat sources for heating and heating, which greatly saves energy and reduces carbon emissions. In the past ...
