Waste heat generator 1 and evaporator 7 and condenser 5 between both and absorber 9 collectively form utilizing waste heat for refrigeration system, benefit
It is produced with fume afterheat for cooling capacity needed for flue gas condensing.Utilizing waste heat for refrigeration system is to complete energy by Absorption Cooling System
The conversion of amount, circulation inner refrigerant-absorbent working medium is a variety of to can be selected, such as lithium bromide-water solution or ammonia-water solution.
Refrigerant-when flue gas passes through waste heat generator 1 in main boiler unit smoke processing system, in waste heat generator 1
Absorbent weak solution can be heated, refriger-ant section evaporation, so that refrigerant-absorbent weak solution becomes concentrated solution, concentrated solution
It is returned in absorber 9 by expansion valve 11, refrigerant vapour enters condenser 5 along pipeline.
Refrigerant vapour cooled water cooling condensation, condenser 5 in condenser 5 in main boiler unit smoke processing system
The refrigerant solution of middle condensation can be sent in evaporator 7 after the decompression of expansion valve 6.
Refrigerant solution in main boiler unit smoke processing system into evaporator 7 is sprayed to evaporation by spray equipment
It in device 7 on heat exchanger, exchanges heat with the damp and hot flue gas being discharged from desulfurizing tower 3, damp and hot flue gas is condensed by cooling, and refrigerant is then
Heating evaporation, damp and hot flue gas condensing water, which can be collected into 3 pond of desulfurizing tower, carries out centralized processing re-using, and part is not steamed
The refrigerant of hair is then pumped to above spray equipment in refrigerant line by circulation and re-starts spray.
The refrigerant vapour evaporated from evaporator 7 in main boiler unit smoke processing system enters suction by pipeline
It receives the refrigerant-absorbent concentrated solution being absorbed in device 9 in device 9 to absorb, the cooled water of the heat that absorption process is released is taken away.
It is dilute to form refrigerant-absorbent after absorbing refrigerant vapour for absorber 9 in main boiler unit smoke processing system
Solution, weak solution, which is sent after being pressurizeed by circulating pump 10 into waste heat generator 1, completes utilizing waste heat for refrigeration system circulation.
Cooling water pipeline enters back into condenser 5 after first passing through absorber 9 in main boiler unit smoke processing system, cold
But water comes from cooling tower, and the cooling water come out from condenser 5, which is sent in boiler, to be utilized.
The course of work of the invention is as follows:
The flue gas being discharged from boiler in main boiler unit smoke processing system passes through waste heat generator 1 first, passes through generator
Heat exchanger 101 transfers heat to the refrigerant-absorbent solution in generator, and the refrigerant being heated in rear solution is evaporated
Become high pressure refrigerant vapor and condenser 5, the refrigerant-absorbent concentrated solution formed after refrigerant evaporation are passed to by pipeline
By being sent after the decompression of expansion valve 11 to absorber 9, wherein high pressure refrigerant vapor pipeline and refrigerant-absorption by pipeline
Agent concentrated solution pipeline carries out heat exchange by heat exchanger 12.
Into the cooled water cooling condensation shape of the high pressure refrigerant vapor of condenser 5 in main boiler unit smoke processing system
Then enter in evaporator 7 after the decompression of expansion valve 6 at refrigerant solution
Evaporation is sprayed to by spray equipment 702 into the refrigerant solution of evaporator 7 in main boiler unit smoke processing system
Device heat exchanger 701 carries out heat with the damp and hot flue gas being discharged from desulfurizing tower 3 and exchanges, and damp and hot flue gas is condensed by cooling, condensed water
It is sent by pipeline to pond centralized processing below desulfurizing tower and is recycled, refrigerant then absorbs damp and hot flue gas heat and evaporates to form low pressure
Refrigerant vapour, the unevaporated refrigerant solution in part collect below evaporator 7, then again by evaporator circulating pump 8
It send to spray equipment 702 and is sprayed.
Absorption is entered by pipeline from the low pressure refrigerant vapor that evaporator 7 comes out in main boiler unit smoke processing system
In device 9, is absorbed from the refrigerant-absorbent concentrated solution being sent in generator 1 in absorber 9, formed below absorber
Refrigerant-absorbent weak solution, refrigerant-absorbent weak solution again by circulating pump 10 pressurize after sent into generator 1, again into
Row utilizing waste heat for refrigeration system circulation.
Flue gas first passes around the completion pair of waste heat generator 1 in main boiler unit smoke processing system after being discharged from boiler
The recycling of smoke pre-heating, flue gas, which can enter in deduster 2, later is dusted processing, can be passed through taken off into desulfurizing tower later
Being provided in sulphuring treatment desulfurizing tower is that water collection device can trap the wandering water in flue gas, and damp and hot flue gas can enter to steaming later
It carries out heat with refrigerant in evaporator heat exchanger 701 in hair device 7 to exchange, damp and hot flue gas drops in evaporator heat exchanger 701
Temperature condensation, condensed water pass to below desulfurizing tower after being collected and are focused on recycling in pond, the flue gas after cooling condensation
It is drained into atmosphere by chimney.
The fume afterheat that afterheat heat exchanger 13 recycles in remaining donkey boiler unit smoke processing system can be used for boiler feedwater
Heating or be used for other systems, wherein evaporator 7 by the condenser 5 of pipeline and main boiler unit smoke processing system and is inhaled
It receives device 9 to be connected, parallel connection is formed with the evaporator 7 in main boiler unit smoke processing system, to reach at multiple flue gases
Reason system shares a set of utilizing waste heat for refrigeration system, on the one hand can save the investment of refrigeration system in this way, on the other hand removes first cigarette
For the waste heat of gas processing system for driving outside refrigeration system, the waste heat of remaining multiple smoke processing system can pass through afterheat heat exchanger
13 are used for boiler feedwater heating or other systems, avoid be completely used for refrigeration system and caused by energy waste.
Embodiment two:
