Description
[technical field]
The utility model relates to a kind of environment-friendly and energy-saving emission-reduction system, particularly relates to a kind of industrial exhaust heat that can make full use of and produces the screw expansion power system that power generates electricity or does work.
[background technique]
The primary energy present situation of China allows of no optimist, though coal resources reserves world rankings second (U.S. the first is a times of China's reserves), the minable coal resources of China are not enough the century-old time, far fewer than the country of world's first six digits coal storage quantity; The oil and natural gas resource of China is also only enough exploited decades, and worldwide petroleum production is shortage within this century also.
Because China's energy resource structure, the energy is not realized sufficient ladder utilization, and the residual heat resources amount is big and widely distributed.For example, the nominal steam pressure of the industrial boiler of the existing considerable part of China is 1.3MPa, and when using, but needs brownout operation, pressure and temperature reducing to use, and causes a large amount of wastes.
At petroleum chemical industry,, also produce a large amount of used heat liquid because be accompanied by a large amount of steam in the manufacturing process.These discarded thermals source that bleed off originally can be recycled.Equally at metallurgy and steel industry, only reclaim one of the flushing cinder spent hot water (80-90 degree) of iron and steel enterprise, just can be for each enterprise brings the electric energy of 2MW 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 of the energy of the energy of discarding more than the flushing cinder spent hot water, thereby recovery far away will be huge.
Especially in cogeneration of heat and power enterprise, the energy loss of many pressure and temperature reducing steam throttlings is arranged at electric power enterprise, and the energy loss of discharging used heat (as the discharging of platoon water).For example low-grade heating hot water generally heats with high-grade steam in the thermoelectricity plant of heating in winter, causes the waste of great energy quality.If heating steam is generated electricity (or dragging load) by screw expander 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.
Aspect geothermal power generation and solar electrical energy generation, screw expander also can provide extraordinary energy pathway.Geothermal water can directly enter screw expander and drive generator for electricity generation, has saved the geothermal water fouling corrosion and has brought the problem of huge investment of system and maintenance, has a extensive future.Solar electrical energy generation originally mainly adopts photoelectric conversion technique, has the problem of cost height and long-term reliability difference; Can utilize the regular solar plate to absorb heat again by the screw expander generating now, the simple and cost of system reduces significantly, has very large application prospect.
In other industry, comprise fields such as building material cement, papermaking printing and dyeing, weaving, sugar industry food, wine industry, pharmaceutical factory, also there is same energy loss problem.
The present Steam Recovery of Convertor system of steel works normally is aggregated into the female pipe of a steam with converter drum steam through steam line, deliver to the thermal accumulator voltage stabilizing through the steam that the female pipe of this steam will gather, the steam of drawing from thermal accumulator supplies plant area's afterheat heat energy system flows vapour behind pressure and temperature reducing.The usual practice of pneumatic steelmaking factory pressure and temperature reducing is to install a Pneumatic/electric modulating valve additional to carry out pressure regulation to reach effect of easing stress the caloic main line of drawing from thermal accumulator both at home and abroad at present.This voltage regulating mode exists remarkable deficiency, and that is exactly that the step-down throttling energy loss of utilizing the modulating valve step-down to be brought is very big, does not meet the policy of the recent energy-saving and emission-reduction that propose of China, construction recycling economy.The energy loss that the step-down throttling can be produced takes certain mode/device just to be reclaimed becomes the problem of people's growing interest.But, the technical problem that it exists following needs to overcome, the first, the steam quality that thermal accumulator provided is saturated vapour (steam quality is low, water content is big), conventional Conversion of energy equipment is inapplicable; The second, there is the certain energy fluctuation in the steam that thermal accumulator provided; The 3rd, plant area's afterheat heat energy system flows is a constant voltage with the vapour vapour pressure, so substitute the effect that the energy recycle device of modulating valve must be able to play decompression and voltage stabilizing.
In sum, a kind of environment-friendly and energy-saving emission-reduction of needs system, it can solve existing energy and utilize inadequate problem.
