Abstract
The present invention is to utilize low temperature exhaust heat circulating generation, with absorption heat pump, electric drive pump coupled heat, using industrial exhaust heat as the power source of power generation, working medium after power generation enters absorption heat pump and electric drive heat pump, drive absorption heat pump, electric drive heat pump for working medium cooling by industrial exhaust heat, the high warm of acquisition obtains electric power for producing for heating.
Description
Technical field
The invention belongs to industrial afterheat recovery field, it is related to a kind of industrial afterheat recovery system and is coupled with B-grade condensation.
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: utilize low temperature exhaust heat circulating generation, and absorption heat pump, electric drive pump coupled heat,
Using industrial exhaust heat as the power source of power generation, the working medium after power generation enters absorption heat pump and electric drive heat pump, passes through industry
Waste heat drives absorption heat pump, electric drive heat pump for working medium cooling, and the high warm of acquisition obtains electric power for giving birth to for heating
It produces.
The technical solution adopted by the present invention is that: the industrial afterheat recovery system of B-grade condensation includes: working medium generator, absorbs
Formula heat pump, compressor, evaporator, with hot family, electric drive heat pump, condenser, evaporator connect compressor, compressor connects working medium
Generator, working medium generator connect condenser, and the working medium after condenser connection absorption heat pump cools down simultaneously is transported to evaporator,
Form power generation major cycle, absorption heat pump high warm outlet connection electric drive heat pump, absorption heat pump low-temperature heat source outlet connection
Condenser, absorption heat pump are connect for heat supply with electric drive heat pump with hot family；
Heat is recycled by absorption heat pump using condenser in the major cycle, absorption heat pump is as level-one waste heat
Recyclable device, electric drive heat pump are used as second level waste-heat recovery device, waste-heat recovery device as remaining heat-recovery condenser, work
Matter generating set pumping driving absorption heat pump, is transported to electric drive heat pump after workmanship, as low-temperature heat source, after doing manual work again with
The Low Temperature Thermal discharge working medium group cooperation of absorption heat pump is transported to evaporator as industrial exhaust heat cooling；
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 compressor is started by external power supply, for working medium heating, is pressurizeed, after working medium generator drive, is generated electricity and connect
For external power supply operation.
The beneficial effects of the present invention are: invention uses working medium of the refrigerant as generating equipment, the absorption and release of heat
Speed is fast, and also low temperature heat user can heat while power generation, exhaust heat utilization effect.
Detailed description of the invention
Fig. 1 is the principle of the present invention figure.
In figure: 1. industrial exhaust heats, 2. evaporators, 3. compressors, 4. absorption heat pumps, 5. working medium generators, 6. heat users,
7, electric drive heat pump, 8, 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, electric drive heat pump 7, condenser 8；The industrial exhaust heat 1 conveys industrial exhaust heat
Working medium is transported to working medium generator 5 and is done manual work, the working medium after workmanship still has one using 3 heating working medium of compressor to evaporator 2
Fixed temperature is transported to condenser 7, and condenser 7 and absorption heat pump 4 exchange heat, as the low-temperature heat source of absorption heat pump, working medium
Generator 5 extracts driving heat source of the high temperature refrigerant as absorption heat pump 4 out, and the high temperature heat drop temperature after driving absorption heat pump 4 is made
For the low-temperature heat source of electric drive heat pump 7, the combinations of sources of heat that two kinds of heat pumps obtain heats for it, drives for being transported to heat user 6
It is combined after heat source workmanship with the low-temperature heat source after workmanship, is re-delivered to evaporator 2, 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.
