The specific embodiment
The present invention is industrial furnace smoke utilizing waste heat for refrigeration heating system as shown in Figure 2, and this system is the waste heat flue gas inlet tube of flue gas type cold/hot water machine of lithium bromide group by Industrial Stoves 1, pressure fan 5, kiln exit flue 3, flue gas type cold/hot water machine of lithium bromide group 8, air-introduced machine 10, bromine cooling machine smoke-intake pipe 6(), and bromine cooling machine smoke exhaust pipe 9(be the waste heat smoke outlet tube of flue gas type cold/hot water machine of lithium bromide group) form.Wherein, the gas approach end of bromine cooling machine smoke-intake pipe 6 is connected on kiln exit flue 3, is provided with smoke valve 7 on bromine cooling machine smoke-intake pipe 6, and general motor-driven valve or the pneumatic operated valve of adopting of this smoke valve 7, also can adopt hand-operated valve.Air-introduced machine 10 is arranged on bromine cooling machine smoke exhaust pipe 9, and the smoke outlet of air-introduced machine 10 is installed and is connected with air-introduced machine chimney 11.Air-introduced machine chimney 11 both can independently arrange (shown in Fig. 2), also can be incorporated to shown in kiln chimney 4(Fig. 3), to reduce the chimney magnitude setting.In kiln exit flue 3, can arrange shown in air preheater 2(Fig. 4) simultaneously.
In Fig. 2, Fig. 3, Fig. 4 system, when the Industrial Stoves operation, while having surplus heat flue gas, 8 groups of startup operations of flue gas type cold/hot water machine of lithium bromide, smoke valve 7 is opened, air-introduced machine 10 starts operation, the part or all of waste heat flue gas that in the kiln exit flue, temperature is higher is by induced draft blower withdraws, enter flue gas type cold/hot water machine of lithium bromide group 8 through bromine cooling machine smoke-intake pipe 6, drive 8 refrigeration (heat) operations of flue gas type cold/hot water machine of lithium bromide group, cold (heat) water for air-conditioning or technique externally is provided; Go out the waste heat flue gas after flue gas type cold/hot water machine of lithium bromide group 8, temperature reduce, enter atmosphere through bromine cooling machine smoke exhaust pipe 9, air-introduced machine 10 and air-introduced machine chimney 11, thereby realize flue gas type cold/hot water machine of lithium bromide group and Industrial Stoves coordinated operation, utilize fume afterheat refrigeration, heat supply.Into and out of the waste heat flue gas flow of flue gas type cold/hot water machine of lithium bromide group, by the control system of flue gas type cold/hot water machine of lithium bromide group, according to refrigeration (heat) the required heat that adds of loading, by the operation to air-introduced machine, control to regulate control.Residue flue gas in the kiln exit flue, under the effect of kiln chimney self draft power, enter atmosphere through kiln chimney.
When flue gas type cold/hot water machine of lithium bromide group is stopped transport, the air-introduced machine stall, smoke valve is closed, and the waste heat flue gas in the kiln exit flue, under the effect of kiln chimney self draft power, enters atmosphere through kiln chimney, i.e. the Industrial Stoves independent operating that can do as usual.
If the flue gas type cold/hot water machine of lithium bromide group (shown in Fig. 5) replaced in Fig. 2, Fig. 3, Fig. 4 by flue gas fuel supplementing type cold/hot water machine of lithium bromide group 18, when Industrial Stoves exhaust smoke level deficiency or Industrial Stoves stoppage in transit, flue gas fuel supplementing type cold/hot water machine of lithium bromide group 18 can start combustion-compensating device heating operation, to meet refrigeration, heat demand.Flue gas fuel supplementing type cold/hot water machine of lithium bromide group 18 needs to install connection bromine cooling machine fuel inlet tube 16 and bromine cooling machine afterburning chimney 17.
For only needing cooling, do not need the application places of heat supply, available flue gas type or flue gas fuel supplementing type lithium bromide adsorption water chilling unit replace flue gas type or flue gas fuel supplementing type cold/hot water machine of lithium bromide group (figure is slightly).
