Detailed description of the invention
With reference to the accompanying drawings the utility model is described in detail, but the utility model is not limited to following embodiment.
As shown in Figure 1, low-grade heat classification recovery and heat pump elevator system, comprise direct combustion heat pump 5, one-level heat regenerator 2, secondary heat regenerator 3, heat supply network backwater 4, circulating line, gas fired-boiler 1, the flue of described gas fired-boiler 1 is provided with one-level heat regenerator 2 successively, secondary heat regenerator 3, the water inlet 21 of described one-level heat regenerator is connected with heat supply network backwater 4, the delivery port 22 of described one-level heat regenerator is connected with gas fired-boiler 1 by pipeline, the water inlet 31 of described secondary heat regenerator, the delivery port 32 of secondary heat regenerator is connected with the evaporimeter 53 of direct combustion heat pump respectively by pipeline, the water inlet 51 of described direct combustion heat pump is connected with heat supply network backwater 4, the delivery port 52 of described direct combustion heat pump is connected with gas fired-boiler 1 by pipeline.
The utility model is provided with two levels of thermal recover on the flue of gas fired-boiler 1, one-level heat regenerator 2 utilizes the fume afterheat of gas fired-boiler 1, about 45 DEG C of heat supply network backwater 4 are heated to about 60 DEG C, without direct combustion heat pump 5, directly enter gas fired-boiler 1 to heat to transfer to again and send net hot water 6, heat pump power can be reduced, reduce equipment investment and reduce operating cost; After one-level heat regenerator 2, the flue gas cool-down of gas fired-boiler 1 is to about 50 DEG C, enter secondary heat regenerator 3, the water inlet 31 of secondary heat regenerator, the delivery port 32 of secondary heat regenerator are connected with the evaporimeter 53 of direct combustion heat pump respectively by pipeline, the fume afterheat of gas fired-boiler 1 is delivered to direct combustion heat pump 5 be used, because heat pump adopts direct-fired, adopts the water at low temperature of lower temperature, below the flue gas cool-down to 25 of gas fired-boiler 1 DEG C, the thermal efficiency is higher.
Above embodiment is to explanation of the present utility model, and non-limiting, when applying, also can change two levels of thermal recovery and heat pump elevator system into multilevel system.It should be noted that, concerning the technical staff of the industry, the simplification carried out according to general principle of the present utility model and structure, conversion, improvement and combination, these all should be included within protection domain of the present utility model.
