Specific embodiment
The eliminating white smoke high effective flue gas hot water type lithium bromide absorption cooling, Hot water units of the utility model are in such as Fig. 2 heating
Room temperature discharge fume fume hot-water type lithium bromide absorption cold, on the basis of Hot water units, be additionally arranged smoke solution heat exchanger 27 and into
Smoke solution heat exchanger weak solution pipeline 28 goes out smoke solution heat exchanger weak solution pipeline 29, the smoke solution heat exchanger added
27 are arranged on 18 smoke exhaust pipe of flue gas heat-exchange unit, and the flue gas come out from flue gas high pressure generator 1 is introduced into flue gas heat-exchange unit 18,
It is discharged after entering back into smoke solution heat exchanger 27；And into the smoke solution heat exchanger weak solution pipeline 28 and out flue gas newly increased
Solution heat exchanger weak solution pipeline 29 is able to achieve purpose there are three types of connection type:
The first such as Fig. 3, newly increase into the setting of smoke solution heat exchanger weak solution pipeline 28 in the outlet of solution pump 6 and cigarette
Between gasoloid heat exchanger 27, the setting of smoke solution heat exchanger weak solution pipeline 29 is high in smoke solution heat exchanger 27 and flue gas out
It presses between generator 1, separates part weak solution from the outlet of solution pump 6 and enter smoke solution heat exchanger 27, this part weak solution goes out
Enter flue gas high pressure generator 1 after coming；
Second of such as Fig. 4, what is newly increased is arranged into smoke solution heat exchanger weak solution pipeline 28 in cryogenic fluid heat exchange
Between the outlet of device 3 and smoke solution heat exchanger 27, the setting of smoke solution heat exchanger weak solution pipeline 29 exchanges heat in smoke solution out
Between device 27 and flue gas high pressure generator 1, separates part weak solution from the outlet of cryogenic fluid heat exchanger 3 and enter smoke solution and change
Hot device 27, this part weak solution enter flue gas high pressure generator 1 after coming out；
Such as Fig. 5, what is newly increased is arranged into smoke solution heat exchanger weak solution pipeline 28 in cryogenic fluid heat exchange for the third
Between the outlet of device 3 and smoke solution heat exchanger 27, the setting of smoke solution heat exchanger weak solution pipeline 29 exchanges heat in smoke solution out
Between 2 import of device 27 and high-temperature solution heat exchanger, it is molten that the weak solution come out from cryogenic fluid heat exchanger 3 fully enters flue gas
Liquid heat exchanger 27, out after fully enter high-temperature solution heat exchanger 2, enter back into flue gas high pressure generator 1.
In cooling condition operation, by heating concentrated solution switching valve 10, heating refrigerant vapour switching valve 11, heating weak solution
Switching valve 23, heating hot water switching valve 25 are all closed, and heating cryogenic fluid pump 22 stops, and flash vessel 19, heating absorber 20 and are adopted
Warm heat exchanger 21 stops circulation, and previous refrigeration cycle process still operates normally, the flue gas come out from flue gas high pressure generator 1
It first passes through that 18 flue-gas temperature of flue gas heat-exchange unit is constant, enters back into smoke solution heat exchanger 27 and changed with the weak solution lower than flue-gas temperature
Heat, flue gas release thermal temperature are reduced to 100 DEG C or so discharges.Compared with fume hot-water type unit of the exhaust gas temperature at 170 DEG C,
The waste heat of 70 DEG C of temperature difference of flue gas has been recycled, refrigeration performance greatly improves more.
In the operation of heating operating condition, cryogenic fluid pump 7 and external system cooling water pump stop, and heating concentrated solution switching valve 10 and adopt
The warm opening of refrigerant vapour switching valve 11, the starting of solution pump 6, heating weak solution switching valve 23 and the opening of heating hot water switching valve 25,
Heating cryogenic fluid pump 22 starts, and previous heating circulation process still operates normally, and the flue gas come out from flue gas high pressure generator 1 is advanced
Enter the water at low temperature far below flue gas saturation temperature that flue gas heat-exchange unit 18 and own system generate to exchange heat, the sensible heat in recovered flue gas
Smoke solution heat exchanger 27 is entered back into after generating effect on moisture extraction while recovered flue gas heat with the latent heat of part water vapour
It exchanges heat with the weak solution for being higher than flue-gas temperature, room temperature flue-gas temperature is increased to 85 DEG C or so discharges, the Gas phase Smoke pair discharged at this time
Humidity reduce and temperature be higher than flue gas dew-point temperature, unit thoroughly eliminated while improving heating performance chimney emit white cigarette show
As protecting environment while reducing thermal pollution, being precipitated since flue gas does not have lime set in chimney, the material of chimney can be used
Conventional material is not necessarily to particular/special requirement.
The cryogenic coolant water far below flue gas saturation temperature that own system generates in the operation of heating operating condition is from sudden strain of a muscle
Steaming device liquid capsule 26 is that cryogenic coolant water in flash vessel liquid capsule 26 is squeezed into flue gas heat-exchange unit 18, low temperature cold by heating cryogenic fluid pump 22
Entering shwoot in lower 19 cavity of flash vessel of pressure after the heating of agent water Mist heat recovering is cryogenic coolant steam, cryogenic coolant
Steam is absorbed by the solution sprayed outside 20 heat exchanger tube of heating absorber, and solution absorbs the heat that cryogenic coolant steam is released and changed
The part low-temperature water heating that heating user comes in heat pipe is taken away, and the solution continuous absorption refrigerant vapour in heating absorber 20 makes cavity
Internal pressure power is maintained at certain value, and flash distillation absorption process constantly carries out, and just produces cryogenic coolant water.19 water as refrigerant moisturizing of flash vessel is leaned on
Pressure difference between evaporator 5 and flash vessel 19 enters flash vessel liquid capsule through cryogenic coolant water supplement pipeline 24 from evaporator liquid capsule 14
26, constantly give 19 moisturizing of flash vessel.It is lower to become concentration after weak solution absorption cryogenic coolant steam in heating absorber 20
Weak solution, by height level pressure difference through heating heat exchanger 21 heating enter absorber cylinder body bottom 13 with it is dilute molten in absorber 4
Liquid mixing, then by solution pump 6 weak solution is sent to heating absorber 20 respectively and sprays, be sent to the concentration of flue gas high pressure generator 1, give
The heat exchange in the smoke solution heat exchanger 27 newly established.
Above scheme is suitable for evaporator 5, absorber 4 can be single hop (as shown in the figure), be also possible to two sections or multistage,
Cooling water can be parallel-connection flow (as shown in the figure) and be also possible to serial flow.
