Figure 10 C is the simplification flow circuit diagram of the flow of solution in Figure 10 B illustrated embodiment, and Figure 10 D is the absorption refrigeration circular chart that flow of solution adopted shown in Figure 10 C.EGT when also showing the temperature that is emitted by miniature gas turbine at absorption-type cold-hot water dispenser among Figure 10 D and be 260 ℃ exhaust gas driven changes.
Circulating temperature is to change from the ratio that absorber A begins to distribute to high-temperature generator GH, Waste Heat Recovery generator GR and cryogenerator GL according to dilute solution.In Figure 10 D, the allocation proportion of dilute solution is set to 30: 20: 50.
Cyclic process is presented among the Du Lintu.Transverse axis among the figure is represented solution temperature, and the longitudinal axis is represented refrigerant temperature (saturation temperature of refrigerant vapour).Solution is discharged from absorber Abs with 38 ℃ temperature, and is assigned among cryogenerator GL, Waste Heat Recovery generator GR and the high-temperature generator GH.In cryogenerator GL, boiling starts from 75.3 ℃ temperature, and along with the concentration of solution increases, the boiling temperature in exit becomes 86.3 ℃.In cryogenerator GL, solution is 88.8 ℃ refrigerant vapour heating by the saturation temperature from high-temperature generator GH supply.In circular chart, the heated side of cryogenerator GL is used as the condenser from the refrigerant vapour of high-temperature generator GH, therefore represents with high temperature condenser CH.In Waste Heat Recovery generator GR, boiling starts from 75.3 ℃ temperature, and along with the concentration of solution increases, the boiling temperature in exit becomes 96.9 ℃.In Waste Heat Recovery generator GR, solution is about 159 ℃ waste gas heating by the temperature of discharging from high-temperature generator GH, and waste gas is used like this, drops to 120 ℃ until waste gas in the exit temperature of Waste Heat Recovery generator GR.
In high-temperature generator GH, boiling starts from 133.7 ℃ temperature, and along with the concentration of solution increases, the boiling temperature in exit becomes 156 ℃.In high-temperature generator GH, solution is by the heating of the waste gas of 260 ℃ of temperature, and waste gas is used like this, drops to 159 ℃ until waste gas in the exit of high-temperature generator GH temperature.
The solution of discharging from above-mentioned corresponding generator can go out to converge in the outlet of Waste Heat Recovery generator GR and cryogenerator GL, and then, the solution of mixing turns back in the absorber.
By the way, the temperature relation shown in Figure 10 D is not changeless, but can according to various conditions for example each the device in heat-conducting area change.
The thermal source of cryogenerator GL is a refrigerant vapour, and solution is heated by latent heat (heat of condensation) under constant condensation temperature.The temperature of thermal source (condensation temperature) is according to outlet and the solution temperature of porch and definite basically.Hope is introduced the dilute solution in whole circulation solutions among the cryogenerator GL with the high partition ratio example, thereby reduces the solution temperature in exit, and reduces the mean temperature that solution goes out at entrance and exit.Like this, can reduce from high-temperature generator GH and as the condensation temperature (saturation temperature) of the refrigerant vapour of the thermal source of cryogenerator GL, and solution boiling temperature from inlet to outlet in high-temperature generator GH can reduce.The flow that flows into the solution among the cryogenerator GL is at least 45% of the solution total flow that flows out from absorber A, be preferably the solution total flow 50% or more than.On the other hand, the upper limit of liquid inventory is subjected to the restriction of various conditions, for example uses the crystallization limit among the high-temperature generator GH of surplus solution, and considers that from the angle of cyclic balance this upper limit should be about 70% of solution total flow.
On the other hand, can change as the sensible heat in the waste gas of the thermal source of high-temperature generator GH and Waste Heat Recovery generator GR, and the variations in temperature of waste gas is that the outlet of high-temperature generator GH and the boiling temperature of porch (solution temperature) change and several times of boiling temperature (solution temperature) variation of the outlet of Waste Heat Recovery generator GR and porch.
Heat exchange relationship when existing a large amount of sensible heats to change mainly is subjected to the influence of heat exchanger type (reverse-flow, parallel type, AC system), and contraflow heat exchanger is comparatively desirable.In addition, the EGT that exports out this moment depends on the temperature (boiling temperature) of porch solution.Therefore, solution should be fed among high-temperature generator GH or the Waste Heat Recovery generator GR by this way, promptly from absorber A, discharge and dilute solution with low concentration and low boiling temperature to introduce among high-temperature generator GH or the Waste Heat Recovery generator GR with the mode of waste gas adverse current.As long as the solution that is supplied has certain a small amount of just enough.
Be fed to the solution total flow that the solution amount among high-temperature generator GH and the Waste Heat Recovery generator GR equals to flow out and deduct the liquid inventory that obtains behind the liquid inventory that is fed among the cryogenerator GL from absorber A.If be fed to the solution amount among the high-temperature generator GH and the ratio between the solution amount among the Waste Heat Recovery generator GR of being fed to is substantially equal to ratio between waste-gas heat that reclaims and the heat that reclaims from high-temperature generator GH from Waste Heat Recovery generator GR, then the change in concentration scope of solution in high-temperature generator GH is substantially equal to the change in concentration scope of solution in Waste Heat Recovery generator GR, thereby makes that circulation is stable.
Solution temperature among the high-temperature generator GH is the temperature that can reach in the economic benefits and social benefits high-temperature generator, and the temperature of the available waste gas of its discharge is usually in about 150 to 185 ℃ scope.On the other hand, the solution temperature among the Waste Heat Recovery generator GR equals the solution temperature that can reach in the single-action generator, and the temperature of the available waste gas of its discharge is usually in about 90 to 120 ℃ scope.
The temperature of supposing the high-temp waste gas that is supplied to absorption-type cold-hot water dispenser is Tgas, and the flow rate ratio of then introducing the absorbent solution among the high-temperature generator GH is preferably approximately { Tgas-(150～185) }/{ Tgas-(90～120) }.In order to ensure the minimum flow of introducing the absorbent solution among high-temperature generator GH and the Waste Heat Recovery generator GR, the flow proportional of introducing the absorbent solution among the high-temperature generator GH should be 10～90% of the solution that is fed among high-temperature generator GH and the Waste Heat Recovery generator GR.
The solution allocation proportion that is fed among high-temperature generator GH and the Waste Heat Recovery generator GR is definite when design, rather than based on controlling such as modes of operation such as partial loads.In addition, the solution allocation proportion that is fed among high-temperature generator GH and the Waste Heat Recovery generator GR can be regulated according to the temperature of introducing the waste gas among high-temperature generator GH and the Waste Heat Recovery generator GR.
