Abstract

The invention discloses a lithium bromide absorption refrigerator with a surface active agent gas phase adding device. The lithium bromide absorption refrigerator comprises an evaporator (1), an absorber (2), a compressor (3), an evaporator pump (4) and an absorber reflux pump (5). The lithium bromide absorption refrigerator is characterized in that the outer side of the absorber (2) is provided with a membrane separation filter (6), and the membrane separation filter (6) is provided with a liquid inlet, a liquid outlet and a water outlet which are connected with a dilute solution outlet of the absorber (2), a concentrated solution inlet of the absorber (2) and a water inlet of the evaporator (1) respectively. The outer side of the evaporator (1) is provided with the surface active agent gas phase adding device (10) which is connected into the upper end of the liquid surface of the evaporator (1) through a pipeline. According to the lithium bromide absorption refrigerator, daily operating cost and the cooling water consumption are reduced, and the pump electric energy consumption is decreased.

Description

technical field [0001] The invention belongs to the technical field of refrigeration, in particular to a lithium bromide absorption refrigerator in which a surfactant is added in gas phase. Background technique [0002] At present, direct-fired lithium bromide absorption type hot and cold water units are generally used. The exhaust gas temperature of the direct-fired high-pressure generator is about 170°C in the cooling condition, and 155°C in the heating condition. At the same time, the flue gas contains part of water vapor, and the saturation temperature of water vapor is about 57°C. The sensible heat of this part of flue gas and the latent heat of condensation of water vapor can account for 10% of the calorific value of fuel combustion. At present, direct emission cannot be used , resulting in a large waste of flue gas waste heat, while generating heat pollution emissions. [0003] Lithium bromide absorption chillers have the advantages of not needing to consume a lot of...
