The generator set of the screw expansion power machine has a rational design and can generate electricity by using low-level thermal energy and collect thermal energy for generation by means of various waste fluid media at a temperature lower than 95 degrees centigrade; moreover, the generation process has excellent stability, easy control, and high efficiency.
Description
Technical field
The utility model belongs to electricity generating device, is specifically related to a kind of screw expansion motor generator set that utilizes low-grade waste heat to generate electricity.
Background technique
In heavy industry industries such as oil, chemical industry, steel-making, because be accompanied by a large amount of steam in the manufacturing process, also produce a large amount of used heat liquid, the thermal source of these discarded dischargings is wasted, equally in metallurgy and iron and steel enterprise, only reclaim one of the flushing cinder spent hot water (80-90 ℃) of iron and steel enterprise, just can be equivalent to the electric energy of 2MW for each enterprise brings to 5MW.
For China of iron and steel output the biggest in the world, its social benefit and economic benefit are immeasurable.In addition, the discarded steam of iron and steel enterprise is also a lot, and the space total amount of the energy of the energy of discarding more than the flushing cinder spent hot water, thereby recovery far away will be very huge.For another example,, generally heat low-grade heating hot water, cause the waste of the great energy with high-grade steam to the thermoelectricity plant of heating in winter; If heating steam is generated electricity (perhaps dragging load) by screw expansion motor earlier, and then heating hot water, can reduce the station-service electric weight significantly, cost of electricity-generating only is the 1/3-1/5 of former power plant cost.Screw expansion motor utilizes system can be translated into mechanical energy as low-quality thermal source, but existing screw expansion motor is not fully utilized as yet.
The model utility content
The utility model has offered a kind of reasonable in design, the screw expansion motor generator set that can utilize low-grade heat energy to generate electricity, and it can utilize the various waste streams body mediums that are lower than 95 ℃, carry out thermal energy collecting and be used for generating, the good stability of power generation process is easy to control, the efficient height.
The technological scheme that the utility model adopted is as follows:
A kind of screw expansion motor generator set, comprise screw expansion motor, it is characterized in that described screw expansion motor is connected with the heat medium circulation loop, this heat medium circulation loop is a closing pipe line, it is provided with steam generator and condenser, and described screw expansion motor drives and connects generator.
In the embodiment, described steam generator is a heat-exchange device, and this heat-exchange device connects setting and contains hot waste fluid medium transport pipeline.
In another embodiment, described heat medium circulation loop comprises heat medium output tube and reflow pipe, be arranged in parallel a pressure regulation tube on the heat medium output tube between steam generator and the screw expansion motor, this pressure regulation tube is provided with pressure regulator valve.
In the embodiment, on the reflow pipe between steam generator and the screw expansion motor condenser is set again, this condenser connection is provided with the condensation inlet and outlet pipe.
In the another embodiment, also be provided with back liquid pump on the reflow pipe between steam generator and the screw expansion motor.
This screw expansion motor generator set adopts the driving force of industrial low grade heat energy as screw expansion motor, for raising the efficiency, this screw expansion motor adopts the equipment of low-temperature evaporation medium as the drive screw expansion motive power machine, this low-temperature evaporation medium is realized circulation by the heat medium circulation loop of sealing, it realizes heat exchange by a steam generator with containing hot waste fluid medium transport pipeline, obtains exchanging heat energy.This low-temperature evaporation medium forms steam and drive screw expansion motive power machine, screw expansion motor drives generator and realizes generating, is converted into once more after through a condenser through the low-temperature evaporation medium of thermal energy consumption liquidly to enter steam generator and finish once more heat exchange and acting by returning liquid pump.
In order to improve the pressure stability of low-temperature evaporation medium, on the heat medium output tube between steam generator and the screw expansion motor, be arranged in parallel a pressure regulation tube, can regulate by pressure regulator valve, make the steam of low-temperature evaporation medium be in pressure plateau, this has improved its stability effectively.
The beneficial effects of the utility model are, this screw expansion motor generator set is reasonable in design, can utilize low-grade heat energy to generate electricity, it can utilize the various waste streams body mediums that are lower than 95 ℃, carry out thermal energy collecting and be used for generating, the good stability of power generation process is easy to control, the efficient height.
Below in conjunction with the drawings and specific embodiments the utility model is further elaborated.
