Rear-heating waste heat coupling system

Abstract

The invention provides a rear-heating waste heat coupling system, belongs to the field of heat supply waste heat recovery and heat distribution, solves the problem that a low-temperature heat source is mixed with a high-temperature heat source for heat exchanging to meet the heating requirement in heating process. A first water outlet of a float glass workshop is introduced into a hot pool througha first water pipe, an inlet of a cooling tower communicated with an upper water pipe, an outlet pipeline of the cooling tower communicated with a cold pool, a outlet of a water mixer is connected with the hot end of an evaporator of a fourth heat pump, the cold end of the evaporator is connected with a second water distributor, the second water distributor is provided with a two-way water dividing valve, one outlet of the water dividing valve is connected with a power plant condensation air return pipe; the medium water of the float glass waste heat is obtained as a low-temperature heat source, the use amount of power plant water is greatly reduced, and the economic benefits are improved.

Description

technical field [0001] The invention belongs to the field of heating waste heat recovery and heat distribution, and relates to a post-heating waste heat coupling system. 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 generation efficiency of a 3 million-kilowatt ther...
