Abstract
Exhaust recovery device of steam turbine is used in a steam turbine that is mechanically vacuumed at its end. Low temperature steam is converted into high temperature steam by mechanical energy to replace the water-cooling tower providing vacuum degree at the end of steam turbine in power generation plant. The waste heat in exhaust can be converted into valuable high temperature steam. No need of cooling water can save water and energy, lower primary investment and cost on steam production, eliminate heat pollution, with less exhaust of harmful CO2 and SO2, and achieve optimum thermal engine efficiency of Rankine cycle.
Description
The present patent application be on April 8th, 2003 by looking into new mechanism: Machinery Ind Information Int. looks into newly, at the result for retrieval of " scientific and technological novelty assessment report ": " through domestic and international 22 databases are inquired about, retrieve 10 pieces of documents, wherein do not have pertinent literature "." it is as follows to reach a conclusion: the information that retrieves similar project exhaust steam in steam turbine recover from domestic and international all ends.This scientific and technological achievement has novelty.”
The present invention refines to form on the basis of the invention technology of patent application 00109865.9 and patent application 01140462.0.
The present invention proposes the mechanical energy that power plant converts to electric energy both at home and abroad first, realize the degree of vacuum of power plant steam turbine end, low temperature vapour is added the steam that is pressed into higher temperature with mechanical energy again, promptly with mechanical energy the low temperature waste vapour is become the valuable energy of high temperature by physical method, industry around giving by line transportation, civil corporation use.
All cogeneration power plant, the thermal power plant in the whole world, comprise the turbine generating system of nuclear reactor, make profits in order to generate electricity to greatest extent, just must pursue steam turbine front and back steam pressure difference maximum, at boiler pressure of steam supply weighing apparatus regularly, has only the overbottom pressure that reduces the steam turbine end, form degree of vacuum and belong to perfect condition, and degree of vacuum is the bigger the better.The previous conviction scholar had invented cooling tower in 100 years, double-curve cooling column, having utilized volume ratio with the low temperature vapour of equivalent and water exactly is 1700: 1 physical property, promptly by the vapour condenser heat exchange huge latent heat of vaporization that exhaust steam is contained, a large amount of cooling waters through the recycle pump conveying, get to the top of cooling tower (or double-curve cooling column), water in dropping process with tower in the air-flow that rises take place that heat is transmitted and water evaporates, thereby realized that the terminal exhaust steam of steam turbine is condensed into water, gas becomes liquid, volume becomes 1 times by 1700 times, volume sharply shrinks, the steam turbine end has had very good degree of vacuum, formed great pressure reduction before and after the steam turbine, greatly limit has realized the purpose that generating is made profits.
100 years previous conviction scholar invention cooling towers, water resources was " inexhaustible, nexhaustible " at that time.And today Tsing-Hua University water conservancy authority clearly warn the society " next century mankind's biggest crisis is a water resources crisis ".
The cooling tower of power plant is maximum thermal waste and the thermo-pollution in the whole world in this century, and the many more boiler of power plant fuel consumptions that can make of thermal waste are big more, thus the CO that boiler chimney discharged
2, SO
2Many more Deng harmful gas, to human survival and just big more to the harm of global village.The black smoke of emerging in the place that China five, sixties boiler chimney are demarcated is many more, indicates that the industry of this area reaches all the more.And the whole world three overall situation crises in this century, wherein preceding two is boiler chimney discharging CO
2Formed Global Greenhouse Effect and stack emission SO
2Formed acid rain causes.This shows, strengthen water saving, energy-saving and environmental protection dynamics, is one of vital task of survival and development of mankind, and the present invention is purpose for power plant saves water and energy to reduce production costs and improve grobal environment for appointing exactly.
The present invention has remedied the defective that the general back pressure type unit of global power plant generates electricity less and the condensed steam type unit is wasted water, heat energy is many.Eliminated power plant's condensed steam type unit vapour condenser, air-extractor, coagulate complete sets of equipment cooling system and technology that water-recorvery apparatus, recycle pump, pipeline, huge cooling tower, big pond are formed.Realized that power plant generates electricity to greatest extent, utilized the Rankine optimal heat engine efficient of heat energy to greatest extent.
The mechanical energy that the present invention converts to electric energy adds the low temperature waste vapour and is pressed into high-temperature water and vapour, is used for factory steam and civil heating refrigeration.Mechanical energy of the present invention be electric energy by power plant by water pump, heat pump, blower fan that motor drove, respectively vapour and water are delivered into one to the several vessels jar; Multiple valve is installed on the pipeline between the container, is comprised the regulation and control system that auxiliary equipments such as modulating valve, differential pressure transmitter, controller, temperature transducer are formed; Form the automatic control system that motors such as water pump, heat pump, air pump, blower fan drag with automatic control auxiliary equipments such as central control room DCS configuration and frequency control of motor speed.The exhaust steam in steam turbine recover of being formed by above device parts, be exactly the low-temp low-pressure exhaust steam of steam turbine to be extracted out and the formation vacuum with mechanical energy, mechanical energy other in the reusing system is pressurizeed the low-temp low-pressure exhaust steam, form vapour and water under the new saturation state, according to required on every side technology specific (special) requirements, definite saturation pressure value that is pressed into that adds, near factory steam furnishes good supplies to, lithium bromide refrigerating idle call vapour, and civil heating heat, even peripheral booth is with warm.Simultaneously, transfer out fractional saturation water, directly return power plant's boiler heating power oxygen-eliminating device recirculation and use from the exhaust steam in steam turbine recover.The above is exactly to propose both at home and abroad the mechanical energy that converts to electric energy first, after steam turbine low-temp low-pressure exhaust steam suction, add the vapour and the water that are pressed into higher temperature again, supply and demand asks department to utilize once more, the maximum change waste vapour in the whole world is the valuable energy, realizes energy sustainable development.Have novelty by looking into newly the present invention as can be known, its principle and structural type have originality, are feasible in reality.
Annex one: new system of Fig. 1 power plant----waste heat energy;
New system of Fig. 2 power plant----makes full use of heat energy;
The former condensing system technological process of Fig. 3 power plant;
The new system process of Fig. 4 power plant.
