Abstract

The invention relates to a negative-pressure self-cooling vapor compression type heat pump and a system thereof. The equipment and the system thereof are mainly applied to the field of steel mill slag washing water waste heat recovery. According to the negative-pressure self-cooling vapor compression type heat pump and the system thereof, a small amount of electric energy is consumed, and waste heat in steel mill slag washing water is extract to supply heat for a building. The negative-pressure self-cooling vapor compression type heat pump consists of a slag washing water inlet (1), a non-condensable gas separator (2), an evaporator (3), a water vapor compressor A (4), a water vapor compressor B (5), a condenser (6), a high-temperature water circulating pump (7), a high-temperature water heat exchanger (8), a subcooler (9), a regulating valve (10), a slag washing water outlet pipe (11), a slag washing water discharge pump (12), a liquid spray electromagnetic valve (13), a vacuum pump A (14), a vacuum pump B (15), a tail end water inlet (16), a tail end water outlet (17) and a slag washing water outlet (18).

Description

technical field [0001] The invention relates to a negative pressure self-cooling vapor compression heat pump and its system. The device and its system are mainly used in the field of waste heat recovery from slag flushing water in steel mills. The negative pressure self-cooling vapor compression heat pump and its system consume a small amount of electric energy , Extract the waste heat from the slag water in the steel mill to heat the building. Background technique [0002] With the increasing tension of energy sources, the issue of energy saving has become the focus of global attention. While actively developing new energy sources, more and more attention is paid to recycling and utilizing waste heat resources. Efficient use of waste heat resources is also an effective way to solve energy shortages. There are a large number of waste heat resources in many industrial fields, and the waste heat resources contained in the slag flushing water of steel mills are representative,...
