Mixing and splitting heat complementary heat pump heating and float glass waste heat recovery combined device

Abstract

The invention discloses a mixing and splitting heat complementary heat pump heating and float glass waste heat recovery combined device, and belongs to the field of heat supply waste heat recovery andheat distribution. The combined device has the technical effect that circulating water participates in secondary heat exchange. An outlet of a low-temperature heat exchange section is connected witha first inlet of a water mixer, an outlet of a water storage tank is communicated with a second inlet of the water mixer, the outlet of the water mixer is connected with the hot end of a evaporator ofa fourth heat pump, the cold end of the evaporator is connected with the second water distributor, the heat end inputs of evaporators of all heat pumps are branch water pipes, the cold end outputs ofthe evaporators of the heat pumps are connected with a cooling tower, the cold end inputs of condensers of the heat pumps is a first water distributor, and the first water distributor is connected with an outlet of a low-temperature heat exchange water pipe of a water return heat supplementary device of a lithium bromide heat pump heating device. The water return heat supplementary device of thelithium bromide heat pump heating device is used for conducting heat exchange on return water and improving temperature.

Description

technical field [0001] The invention belongs to the field of heating waste heat recovery and heat distribution, and relates to a combination device of heat pump heating with mixed heat supply and float glass waste heat recovery. Background technique [0002] In recent years, with the increase of urban heating area in my country and the increase of production line construction in industrial plants, the heat consumption in my country has increased rapidly. From the analysis of heating methods, there are currently the following ways for residents to heat in my country: thermoelectricity Combined production mode, central heating of small and medium-sized regional boiler rooms, small domestic gas water heaters, household coal-fired furnaces, etc., among which the combined heat and power mode is a combination of using the high-grade thermal energy of the fuel to generate electricity and then using its low-grade thermal energy for heating Use energy technology. At present, the avera...

Problems solved by technology

However, the low-temperature industrial waste heat represented by the float glass factory is currently being discarded for nothing, or it is discharged using additional hydropower resources. It is a pity to discard it.
