Lithium bromide heat pump heating device for cogeneration of no-mixing supplementary heating power plant

Abstract

The invention relates to a lithium bromide heat pump heating device for cogeneration of a no-mixing supplementary heating power plant, and belongs to the field of waste heat recovery and heat distribution. In order to solve the problems that the heat quality of high-temperature steam of the power plant is gradually increased and the water outlet temperature of a pipeline on a user side outputs ladder energy, an outlet of a high-temperature heat exchange water pipe is connected to the hot end of a fourth heat pump evaporator, and a low-temperature heat exchange water pipe is connected with a third output pipeline; the cold end of the fourth heat pump evaporator is in output connection with a water return pipe of a condenser of the power plant, and the hot end of the condenser of a heat pumpis in output connection with a fourth output pipeline; and an outlet of a third lithium bromide heat pump unit communicates with an inlet of a moderate-temperature heat source of a second lithium bromide heat pump unit, and an outlet of the moderate-temperature heat source of the second lithium bromide heat pump unit communicates with an inlet of a moderate-temperature heat source of a first lithium bromide heat pump unit. The lithium bromide heat pump heating device has the effects that the temperature can reach or approach 100 DEG C. The water outlet temperature of the pipeline on the userside outputs the ladder energy.

Description

technical field [0001] The invention belongs to the field of heating waste heat recovery and heat distribution, and relates to a lithium bromide heat pump heating device for cogeneration of heat and electricity in a non-mixed heating power plant. 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.
