Abstract
The invention discloses a heat pump waste heat recovery system which comprises a heating station, a heat exchanger unit, a power station boiler, a turbine, a steamer, a power plant cooling tower and an adsorption heat pump. The heating station is connected with the heat exchanger unit and the adsorption heat pump through a heat pipe; and the turbine is connected with the heat exchanger unit, the adsorption heat pump and the power station boiler through a pipeline. The steamer is connected with the turbine, the power plant cooling tower and the adsorption heat pump through a pipeline. Waste heat of the power station boiler is used for heat supply to users by means of the effects of the heat exchanger unit and the adsorption heat pump and finally through the heating station; and the shortcomings that in the prior art, the waste heat of a power station is not utilized fully and the optimal use effect of energy cannot be achieved are overcome.
Description
Technical field
The present invention relates to heat recovery technical field, especially a kind of heat pump recovery waste heat system.
Background technique
Power station, as the feed end of electric power energy, it builds the supply for electric energy or very important effect is played in the development to State Grid.
At present, it is low that many power station also exist heating efficiency, especially utilization rate of waste heat is lower, and then cause the waste of the energy, the personnel of power plant's work, winter, arctic weather carried out warming oneself that you generally need design heating arrangement separately to carry out heating, not only caused the waste of resource, and cost is higher, the whole economic efficiency for power plant impacts; If design a kind of can to the bootstrap system of boiler of power plant, just can realize the abundant use of resource and the effect that is improved of the whole economic efficiency of power plant.
Prior art is difficult to the productive life needs meeting people, and for the problems referred to above, the present invention aims to provide a kind of heat pump recovery waste heat system.
For realizing this technical purpose, the technical solution used in the present invention is: a kind of heat pump recovery waste heat system, comprises heating plant, heat changes planes group, station boiler, steam turbine, steamer, power plant cooling tower and absorption heat pump; Described heating plant is changed planes by heat pipe and heat and to be organized and absorption heat pump is connected; Described steam turbine connects heat by pipeline and to change planes group, absorption heat pump and station boiler; Described steamer connects steam turbine, power plant cooling tower and absorption examination heat pump by pipeline.
As further technological scheme of the present invention: described absorption heat pump connects steamer by solidifying water back boiler pipeline; Described steamer also be connected power plant cooling tower and absorption heat pump connecting line is connected by three-way pipe.
As further technological scheme of the present invention: described steam turbine side is provided with generator set
Compared with prior art, the invention has the beneficial effects as follows: this heat pump recovery waste heat system, it, by the effect of the waste heat of boiler of power plant through overheated change planes group and absorption heat pump, carries out heat supply finally by heating plant to user; Change power station UTILIZATION OF VESIDUAL HEAT IN in prior art insufficient, the deficiency of the best using effect of the energy can not be reached; Global design is simple, practical, is easy to promote the use of.
