Problems solved by technology

[0002] The country vigorously advocates waste heat recovery and clean energy heating, but most clean energy costs are relatively high, such as high-grade energy such as natural gas and electricity. Using such high-grade energy for heating is a great waste of energy, while industrial waste heat is The most valuable clean energy, because the heat temperature required for heating is not high, most of the industrial waste heat can meet
The usual industrial waste heat recovery technology only recovers high-temperature waste heat, and low-temperature waste heat still needs to be cooled before it can be used. Cooling waste heat also consumes part of electricity and water resources.

Embodiment Construction

[0010] A coupling technology of industrial waste heat recovery system and peak shaving heat supply, industrial waste heat 1, evaporator 2, working medium pump 3, absorption heat pump 4, working medium generator 5, heat user 6, condenser 7, peak shaving heat source 8 The industrial waste heat 1 transports the industrial waste heat to the evaporator 2, heats the CO2 working medium, and the CO2 working medium is transported to the working medium generator 5, and the CO2 after work is gaseous, still has a certain temperature, and is transported to the condenser 7, The condenser 7 exchanges heat with the absorption heat pump 4, and serves as the low-temperature heat source of the absorption heat pump, and the high temperature produced by the peak-shaving heat source is used as the driving heat source of the absorption heat pump 4, and the obtained heat source is sent to the heat user 6 for heating, After the heat source is driven to work, it is sent back to the peak heat source to r...

Abstract

The invention discloses an industrial waste heat recovery system and peak-load-regulating heat supply coupling technology. The industrial waste heat recovery system and peak-load-regulating heat supply coupling technology is characterized in that low-temperature waste heat for circulating electricity generation is coupled with a peak-load-regulating heat source and an absorption heat pump; the industrial waste heat serves as a power source for electricity generation, a working medium after electricity generation enters a condenser, then the industrial waste heat is used for supplying heat through the absorption heat pump, and electricity is obtained for production.

Description

technical field [0001] The invention belongs to the field of industrial waste heat recovery, and relates to a coupling technology of an industrial waste heat recovery system and peak-shaving heat supply. Background technique [0002] The country vigorously advocates waste heat recovery and clean energy heating, but most clean energy costs are relatively high, such as high-grade energy such as natural gas and electricity. Using such high-grade energy for heating is a great waste of energy, while industrial waste heat is The most valuable clean energy, because the heat temperature required for heating is not high, most of the industrial waste heat can be satisfied. The usual industrial waste heat recovery technology only recovers high-temperature waste heat, and the low-temperature waste heat still needs to be cooled before it can be used. Cooling waste heat also consumes part of electricity and water resources. Contents of the invention [0003] The problem solved by the p...
