Description
Technical field
The utility model belongs to Steam Power Circulation field, is specifically related to a kind of steam exhaust steam regenerating unit.
Background technology
Rankine cycle (English: Rankine Cycle) being also referred to as rankine cycle, is a kind of thermodynamic cycle that heat energy is converted into merit.Lang Ken circulation absorbs heat from the external world, by the working medium of its closed loop (conventionally making water) heating, realize heat energy and transform acting.Although Rankine cycle is theoretical, be born in mid-term in 19th century, even if to today, Lang Ken circulation still produces 90% electric power in the world, comprises the power station of nearly all solar energy, biomass energy, coal and nuclear energy.Lang Ken circulation is the elementary heat mechanics principle of supporting steam engine.
Because also there is inevitable historic Limitation of Some Different in the age that Lang Ken circulation is born,, there is some defects and deficiency in the thermodynamic (al) mechanical condition of that age study, Hydrodynamics Theory and have a long way to go now unavoidably.
Rankine cycle realizes the closed loop cycle of working-medium water, significantly reduces the consumption of water resource, but in order to realize closed loop, except being water by water vapor condensation, and then almost can not pressurizeing by compressed liquid refrigerant, just can make it to enter next pressures cycle.Compression process efficiency for incompressible fluid is very high, so the effect of water pump is most important in whole circulation, but energy consumption is often ignored.
Realizing the common method that steam directly utilizes is machinery recompression, owing to needing to consume mechanical energy in the course of work, by law of conservation of energy intuitively, analyzes, and does not all adopt this technology to realize steam recirculation in practical application.
Do not consider at that time recuperation of heat, the amount of heat that forms condensing link must scatter and disappear with low temperature form.In addition, the heat of condensation of water is almost maximum in common working medium, and work temperature section is also higher, but considers condition at that time, from composite factors such as cost, security, environmental protection, considers, up to now, also only having water is optimal working medium.
Multiplex backheat in the theoretical application of current traditional Rankine cycle, the improvements endless form such as heat is raised the efficiency again, also adopts critical, the overcritical mode of operation of increase vapor (steam) temperature, pressure to raise the efficiency.The basic thinking of these methods is all to improve as far as possible effective merit all to consume the ratio in heat energy.
The main starting point of method that also has other is to manage to adopt the mode that consumes a small amount of heat energy, mechanical energy, directly, indirectly the low-temperature waste heat of discharge is recycled, for links such as industrial hot water preparation, heating for residential area, realize UTILIZATION OF VESIDUAL HEAT IN and improve effective merit in whole ratios that consume in heat energy.
Above-mentioned two kinds of methods in cost, security, raising ratio, apply the aspects such as convenient feasibility and be all subject to many limitations, be difficult to realize increasing substantially of utilization efficiency of heat energy, be particularly difficult to realize increasing substantially of conversion efficiency of thermoelectric.
Some basic principle of hydrodynamics the inside, has certain " special " function, in process fluid flow, as the material property of fluid itself, also can attach and realize conductive thermal exchange, mass transfer, material compression texts.Unique feature, is exactly to be nearly all in the situation that not needing mechanical device motion, only at spatial variations, thermal energy transfer, flow process, just can realize.
Gas amplifier principle: after the narrow annular channel of gases at high pressure by 0.05～0.1 millimeter of gas amplifier, to a side spray, go out, by Koln, reach effect principle and the special geometry of gas amplifier, the low-pressure gas that opposite side maximum is 10 ~ 100 times can be inhaled into, and from gas amplifier homonymy, blows out together with original gases at high pressure.Gas amplifier (air amplifier) application was expanded rapidly over the past two years, and conventional vast scale is saved compressed air, and utilized compressed air to realize the commercial Application such as drifting dust, dust suction, material transport.Technology maturation is stable.
If the gas being inhaled into is low temperature, low-pressure steam, driving air-flow is high temperature, high pressure superheated steam, when high-temperature steam sprays from annular jet, meeting expansion, cooling, step-down, mix with low temperature, low-pressure steam simultaneously, reach heat, momentum balance, final air-flow is middle temperature, middle pressure mixed vapour, from outlet, discharges.
When vapor flow speed is little, following law is all suitable for:
Boyle's law: during temperature constant, the product of the pressure of a certain amount of gas and its volume is constant.Mathematic(al) representation is: pV=constant (n, T are constant) or p1V1=p2V2(n1=n2, T1=T2).
Charlie-lid Gay-Lussac gas law: during constant pressure, the volume of a certain amount of gas (V) is directly proportional to its temperature (T).
According to above-mentioned two laws, in analysis Rankine cycle, do not mention that the gas in vapor transmission process is pneumatic, thermodynamic problems, only steam is gone to research according to perfect condition, have some limitations.
At highly energy-consuming environment such as thermal power plant, chemical plant, tire plant, use in a large number steam, these steam become the steam that temperature is lower after discharging temperature or pressure, and this steam is referred to as exhaust steam.The difficulty of the regeneration of exhaust steam is at present very large, is limited to existing theory, if mechanical energy is examined in exhaust steam regeneration, carries out supercharging, benefit, and cost is very high, so generally do not adopt mechanical energy to pressurize to realize the recycling of mechanical energy.
Thermal power plant's Lang Ken circulation that generally also employing is practical more than 100 year at present, the link wherein consuming energy is most exhaust steam regeneration, what adopt is, by condenser, exhaust steam is condensed into condensed water, condensed water is pressed into high pressure link by water pump from low pressure link, then in high pressure link, realize isobaric concurrent heating and increase enthalpy, this link is owing to being to discharge a large amount of heat energy under the condition of low temperature, give the cooling very large burden of bringing, the lower heat of large amount temperature simultaneously discharging is difficult to recycling, wasted amount of heat, also cause the efficiency of thermal power plant all the time in 42 35 percent to percent left and right, be difficult to large breakthrough.
Also there are at present two kinds of modes to solve this problem, a kind of is steam heat again, a kind of is steam backheat, steam again heat is a part of heat that sheds in steam use procedure, when also having certain heat, adopts boiler to carry out concurrent heating, enter next acting process, limited increases operation rate, and reduces as far as possible useful merit and the ratio of the heat radiation of condensing in a large number, has relatively improved the utilization rate of heat; Backheat is in the situation that steam also has certain pressure and temperature, utilize especially pressure, mix heat with the water after condenser condenses, be used for the backheat of circulation, condensed water heated up, but do not reach boiling, by water pump, be pressed into the isobaric pressurization that heats up of boiler, reduced by condensed water and dispelled the heat, these two kinds of modes all can not realize intensification, the pressurization in minimum enthalpy situation, can not realize heat energy utilization; Effect is little, and system complexity is larger, owing to not realizing a large amount of steam utilizations, is not the way of at all dealing with problems.
