Technical field
The present invention relates to reducing-and-cooling plant technical field, particularly the rotary reducing-and-cooling plant of one.
Background technique
At present, reducing-and-cooling plant is a kind of steam thermal energy parameter (pressure, the temperature) transition device of enterprise's extensive uses in Thermal Power Engineering such as cogeneration of heat and power in modern industry, central heat supply (or steam supply) and light industry, electric power, chemical industry, weaving, pass through reducing-and-cooling plant, original steam parameter is dropped to user and needs suitable temperature and pressure, to meet the requirement of user.But in the process, because common reducing-and-cooling plant is the object being realized pressure and temperature reducing by throttling and spray boiler feed water, and throttling is a typical irreversible entropy increasing process, causes having and consume energy and the drawback of water consumption, cause a large amount of efficient resource wastes.
Model utility content
For consuming energy in prior art and the drawback of water consumption, the purpose of this utility model is to provide a kind of rotary reducing-and-cooling plant, pressure difference before and after pressure and temperature reducing is utilized to realize top pressure power generation or drive driving machinery and control system work, the energy lost that steam quality after pressure and temperature reducing declined is converted to kinetic energy by rotary reducing-and-cooling plant, eliminates former reducing-and-cooling plant and consumes energy and the drawback of water consumption.
Its technological scheme is: a kind of rotary reducing-and-cooling plant, comprises screw expander or turbine engine, driving machinery and control system, generator, grid-connection cabinet, contact cabinet and transformer; It is characterized in that: connect driving machinery and control system by described screw expander or turbine engine one end, as the power part of driving machinery and control system, the other end drive electrical generators, the power that generator is provided by screw expander or turbine engine generates electricity, and by electric power successively by grid-connection cabinet, contact cabinet and transformer access electrical network.
Preferably, the front end of described screw expander or turbine engine is provided with fast valve, fast valve connects modulating valve and is provided with steam access port by pipeline coming steam direction, and the rear end of screw expander or turbine engine is connected to by outlet valve and pipeline and arranges steam direction and be provided with steam (vapor) outlet.
Compared with prior art, after this rotary reducing-and-cooling plant puts into serial production operation, originally discarded pressure reduction can be converted into available kinetic energy or electric energy, realize turning waste into wealth, and decreasing the consumption of boiler feed water, is that industry energy conservation lowers consumption effective approaches and methods.While realization obtains economic benefit, environmental protection effect is highly significant also.
Accompanying drawing explanation
Fig. 1 is system construction drawing of the present utility model.
Embodiment
Referring to accompanying drawing, the utility model is described in detail.
With reference to Fig. 1, a kind of rotary reducing-and-cooling plant, comprises screw expander 1, driving machinery and control system 2, generator 3, grid-connection cabinet 4, contact cabinet 5 and transformer 6; Driving machinery and control system 2 is connected by described screw expansion 1 machine one end, as the power part of driving machinery and control system 2, the other end drive electrical generators 3, the power that generator 3 is provided by screw expander 1 generates electricity, and electric power is accessed electrical network by grid-connection cabinet 3, contact cabinet 4 and transformer 5 successively; The front end of described screw expander 1 is provided with fast valve 9, fast valve 9 connects modulating valve 8 and is provided with steam access port 7 by pipeline coming steam direction, and the rear end of screw expander 1 is connected to by outlet valve 10 and pipeline and arranges steam direction and be provided with steam (vapor) outlet 11.
Above-mentioned screw expander 1 can be replaced with turbine engine.
Its know-why is: promote screw expander 1 after directly entering screw expander 1 with the water vapour of certain pressure and temperature and rotate and carry out expansion work, external output mechanical work, as the power part of driving machinery and control system 2, or drive electrical generators 3 generates electricity, finally become low temperature, Low pressure steam leaves screw expander 1 and enter former pressure and temperature reducing line exit point, enter downstream process.
Due to rotary reducing-and-cooling plant be with bypass mode realize pressure and temperature reducing run, with former reducing-and-cooling plant for shunting device is parallel to rotary reducing-and-cooling plant, coordinate main stop valve exhaust steam pressure is regulated.In the course of the work; rotary formula reducing-and-cooling plant mainly with rotating speed and load for control device; throttle flow is controlled by main stop valve; process parameter (pressure, temperature, flow) after adjusting rotary speed and valve; guarantee outlet vapor pressure, temperature parameter meets former technological requirement; can not have an impact to the normal production of original tooling during operation, and guarantee stable operation of unit.
Its economic benefit data run are as follows: pressure is that 2.2MPaA saturated vapour pressure after rotary reducing-and-cooling plant reduces to the saturated vapour of 1.3MPaA, flow is 25t/h, run 8000h per year to calculate, then year total net electric generation 249.6 ten thousand degree, electricity price presses kilowatt-hour 0.5 yuan calculating, year total power benefit 124.8 ten thousand yuan, save mark coal amount 1008t year, reduce CO2 emission 2488t, sulfur dioxide (SO2) emissions 74.88t.
Above mode of execution is only in order to illustrate the technical solution of the utility model and unrestricted, although be described in detail the utility model with reference to above mode of execution, those of ordinary skill in the art should be appreciated that and can modify to the technical solution of the utility model or be equal to the spirit and scope of replacing and should not depart from technical solutions of the utility model.
