Abstract

The invention discloses a heating apparatus, heated at the rear, comprising a lithium bromide heat pump and used in combined heat and power generation of a power plant, belongs to the field of residual heat recovery of heat supply and heat distribution, and aims to solve the problems about provision of a high-temperature heat source for the lithium bromide heat pump and a mismatch between heat supply and demand. An outlet of a water storage tank is connected with a solar water heater through a pipeline; a sixteenth control valve is arranged on the pipeline; two branches of a water outlet pipeof the solar water heater are connected with water pipes in parallel; a thirteenth control valve is arranged on one water pipe, which is connected with a fifth circulating pump; each lithium bromide heat pump unit comprises a high-temperature heat source, a low-temperature heat source and a medium-temperature heat source; and a heat exchange pipeline of a waste steam device is communicated in parallel with an evaporator of a steam heat pump unit and the low-temperature heat sources of all the lithium bromide heat pump units. The effects are: providing the high-temperature heat source for the lithium bromide heat pump and realizing water recycling in the power plant.

Description

technical field [0001] The invention belongs to the field of heating waste heat recovery and heat distribution, and relates to a post-heating lithium bromide heat pump and power plant cogeneration heating device. 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 average power generat...
