Description

Steam Turbine Driven open-type heat pump assembly
Technical field
The utility model relates to a kind of heat pump, is Steam Turbine Driven open-type heat pump assembly.
Background technology
Can emit a large amount of low temperature exhaust heats in the cogeneration of heat and power process, meanwhile, in the production process of heat energy and electric power, also need the not too high heat energy of a large amount of grades, for example the heating process of boiler feedwater.If can the part low temperature exhaust heat of power plant condenser discharging be recycled by heat pump techniques, be applied to again after upgrading in the feedwater heating, then can save operating cost in a large number, reach the purpose of environmental protection simultaneously, and the form that adopts usually at present is: by the mode of common electronic compression heat pump, with the drive energy of electric energy as heat pump, compressor adopts open-type or semi-enclosed form, absorb the low-grade heat in the recirculated water, in the condenser of heat pump, finish heating process again to boiler feedwater, though this form has also been utilized the used heat in a large amount of recirculated waters, but drive energy comes from the electric energy that power plant self produces, improve the station service power consumption rate of power plant, consumed the product of self, be equivalent to reduce the generated energy of power plant; From the using energy source angle, the generating efficiency in power plant generally is no more than 40% simultaneously, though extracted the used heat in the recirculated water, the heat of still old about 2.5 times heat pump power consumption can't utilize, and finally dissipates in atmosphere by cooling tower.
The utility model content
For addressing the above problem, the utility model provides a kind of Steam Turbine Driven open-type heat pump assembly that adopts back yard industry Steam Turbine Driven opened compressor.
The technical scheme that this device adopted is as follows: comprise the refrigerant loop that is joined end to end in proper order and formed by evaporimeter, compressor, condenser, expansion valve, and the power input source that is connected with compressor, it is characterized in that the described power input source that is connected with compressor is a steam turbine.
Described compressor is an opened compressor.

Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further details
Fig. 1 is the utility model system architecture schematic diagram
The specific embodiment
Steam Turbine Driven open-type heat pump assembly as shown in Figure 1 comprises the refrigerant loop that is joined end to end and formed by evaporimeter 1, opened compressor 2, condenser 3, expansion valve 4 orders, and the steam turbine 5 that is connected with opened compressor 2.Boiler provides overheated or saturated vapor, drag opened compressor 2 work by steam turbine 5, steam turbine 5 adopts transmission joint direct connection with opened compressor 2, the rotating speed of steam turbine 5 is to reach by the air inflow that control enters steam turbine 5, and steam can also enter other heating position and continues to utilize discharging the exhaust steam that forms behind the high-grade energy simultaneously.
For the outlet temperature that makes this heat pump assembly further improves, the working medium of heat pump no longer is confined to common cold-producing medium such as R22 and R134a etc., also can adopt special non-azeotropic or inferior azeotrope refrigerant, through facts have proved, adopt the heat pump of these working medium, leaving water temperature can reach more than 85 ℃, also has simultaneously than higher heating efficiency, therefore need select suitable cold-producing medium according to the temperature of electric power plant circulating water and the temperature that heats of requirement, to improve the Energy Efficiency Ratio of unit as much as possible.
During work, the low temperature and low pressure steam of evaporimeter 1 outlet is inhaled in the opened compressor 2, after in opened compressor 2, forming the gas of HTHP, enter in the condenser 3, here, be lower than the boiler feedwater heat release of condensation temperature to temperature after, become the liquid of HTHP, through after the throttling of expansion valve 4, become the vapour-liquid mixture of low-temp low-pressure, enter the heat that absorbs power plant's cooling circulating water in the evaporimeter 1 then, the gas that flashes to low-temp low-pressure again enters and finishes once circulation in the opened compressor 2.
Through calculating, adopt Steam Turbine Driven open-type heat pump assembly, can reach 2.5 with the contained whole heat energy of the steam Energy Efficiency Ratio that is radix and (feedwater is heated to 50 ℃ from 30 ℃, the electric power plant circulating water mean temperature is 30 ℃) more than, substantially exceeding steam directly heating or common electronic compression heat pump heating system, is a kind of energy saver very efficiently.
