Abstract
The present invention is to be coupled using low temperature exhaust heat circulating generation with absorption heat pump, and using industrial exhaust heat as the power source of power generation, the working medium after power generation enters condenser, by absorption heat pump, industrial exhaust heat is used to heat, and obtains electric power for producing.
Description
Technical field
The invention belongs to industrial afterheat recovery field, it is related to a kind of industrial afterheat recovery system with absorption heating and couples skill
Art.
Background technique
Country advocates waste heat recycling, clean energy resource heating, but most clean energy resource higher cost energetically, such as naturally
Gas, this kind of high-grade energy of electricity, being heated using this high-grade energy is significant wastage to the energy, and industrial exhaust heat is most
Valuable clean energy resource, because thermal temperature needed for heat supply is of less demanding, most industrial exhaust heat can all meet.And it is usual
Industrial afterheat recovery technology only high-temperature residual heat is recycled, low temperature exhaust heat still need it is cooling after can just be utilized, it is cooling
Waste heat also needs to consume part electric energy and water resource.
Summary of the invention
Problems solved by the invention is: utilizing low temperature exhaust heat circulating generation, couples with absorption heat pump, utilize industrial exhaust heat
As the power source of power generation, the working medium after power generation enters condenser, by absorption heat pump, industrial exhaust heat is used to heat,
Electric power is obtained for producing.
The technical solution adopted by the present invention is that: the industrial afterheat recovery system of absorption heat pump condensation includes: working medium power generation
Machine, absorption heat pump, working medium pump, evaporator, with hot family, condenser, evaporator connects working medium generator, the connection of working medium generator
Condenser, condenser connect absorption heat pump, while connecting working medium pump, form power generation major cycle, absorption heat pump with hot family
Connection is used for heat supply；
It is exchanged heat in the major cycle using absorption heat pump and condenser, the pumping driving of working medium generating set is absorption
Heat pump, while the low-temp low-pressure working medium after workmanship is as low-temperature heat source；
The working medium selects CO2, and working medium pump forms circulation for CO2 in system, and working medium generator selects CO2 generator
Group.
The beneficial effects of the present invention are: invention uses working medium of the CO2 as generating equipment, the absorption of heat and rate of release
Fastly, low temperature heat user can also be heated while power generation, exhaust heat utilization effect is good.
Detailed description of the invention
Fig. 1 is the principle of the present invention figure.
In figure: 1. industrial exhaust heats, 2. evaporators, 3. working medium pumps, 4. absorption heat pumps, 5. working medium generators, 6. heat users,
7. condenser.
Specific embodiment
A kind of industrial afterheat recovery system and absorption heating coupling technique, industrial exhaust heat 1, working medium pump 3, are inhaled evaporator 2
Receipts formula heat pump 4, working medium generator 5, heat user 6, condenser 7；Industrial exhaust heat is transported to evaporator 2 by the industrial exhaust heat 1, is added
Hot CO2 working medium, CO2 working medium are transported to working medium generator 5, and the CO2 after workmanship is in gaseous state, still have certain temperature, are transported to cold
Condenser 7, condenser 7 and absorption heat pump 4 exchange heat, and as the low-temperature heat source of absorption heat pump, working medium generator 5 extracts high temperature work out
Driving heat source of the matter as absorption heat pump 4, the heat source of acquisition heat, driving heat source is done manual work for being transported to heat user 6 for it
It is combined afterwards with the low-temperature heat source after workmanship, using working medium pump 3, is re-delivered to evaporator, cooled down for industrial exhaust heat 1.
The present invention is not limited to the present embodiment, any equivalent concepts within the technical scope of the present disclosure or changes
Become, is classified as protection scope of the present invention.
