Abstract
The invention discloses a regenerative method of exhaust steam in a thermal power station, which relates to the field of saving energy, reducing emission and regenerating resource. The invention is characterized in that the method adopts pollution-free natural water as raw material; after the natural water forms high-temperature high-pressure steam by a boiler and is used for generating power, fractional condensation and collection are carried out on exhaust steam exhausted into condensing tower by a steam turbine so as to form step water-level potential energy with different heights; and then step type hydraulic power generation is carried out from high level to low level. The method utilizes the principle that the higher the steam rises, the more the set levels are, the larger the water-level potential energy of the condensing water is, the larger the generated energy is; in the method, the condensing water formed by the sterilized steam with high temperature and high pressure is utilized and recovered and purified after hydraulic power generation so as to form pure water with high purity; and further, the pure water can absorb mineral nutrients by a multielement mineral filter layer, thus producing mineral drinking water. The regenerative method does not improve resource consumption of the thermal power station, comprehensively utilizes the exhaust steam for three times without reducing once generated energy simultaneously, and fully converts the exhaust steam into commodities, thus not only increasing the economic benefit obviously, but also reducing the discharge of exhaust steam and waste water.
Description
Technical field
The present invention relates to energy-saving and emission-reduction and renewable sources of energy field, be specifically related to hydroelectric power and purified water, potable water field.
Technical background
Existing Thermal Power Station, it is the steam electric power that common water heating vaporization is formed High Temperature High Pressure, tail gas after the generating is except that being used for cold season the heating room, there is time of 3/4ths to discharge or reclaim condensed water naturally in 1 year, cause the wasting of resources. and reclaim condensed water, be tail gas to be transported to very high condensing tower form condensed water, condensed water is dropped on the sink of condensing tower by eminence, naturally drain return pipe to the downstream, recycling, the just power generation mode of " water--steam-thermoelectricity-waste steam-condensed water ".This kind electricity-generating method, the complementary energy of the waste steam of discharging is not fully used.At present China does not still have important breakthrough aspect the bled steam of thermoelectricity plant utilizes. and China the new technology of steam generating occurred the chimney waste heat is converted to, as the patent No. 200610045831.6 and patent No. 200610048232.X. aspect blast furnace waste gas utilizes
The objective of the invention is, the method for thermoelectricity plant's waste steam regeneration of a kind of " waste steam-condensed water-hydroelectric power-purified water-mineral substance potable water " is provided, promote the energy-saving and emission-reduction of existing thermoelectricity plant, improve the value of its by-product.
The object of the present invention is achieved like this: with free of contamination natural water is raw material, after boiler forms the high pressure high temperature vapor generating, the waste steam that the steam turbine power generation unit is discharged passes condensate collector step by step through condensing tower, the condensed water of collecting in the condensate collectors at different levels (6) is drained into collector pipes at different levels respectively, form the water level potential energy of multistage different heights, the water of collector pipes at different levels is by the rudimentary extremely senior pressure supply water pipe that enriches step by step, make penstock possess high water level potential energy. to close again and open the generating of hydroelectric power unit then. high water level potential energy to rudimentary, is carried out the ladder-type hydroelectric power by senior.The height that this method utilizes steam to rise is higher, the progression of setting the more, the water level potential energy of condensed water is just bigger, generated energy is just bigger; The condensed water that this method and the steam that utilizes high pressure-temperature to sterilize form, after hydroelectric power, impurity such as reclaiming clean scrap metal form highly purified purified water; Purified water further filters through multi-element mineral matter and absorbs mineral matter nutritional, forms the mineral substance potable water.
Good effect of the present invention is: when not improving Thermal Power Station's energy consumption, not reducing by generated energy, waste steam is carried out three comprehensive utilizations again, and all be converted into commodity, not only newly-increased remarkable in economical benefits has also reduced the discharging of gas and waste water.

Mode of execution
Below in conjunction with accompanying drawing, the present invention is further elaborated:
As shown in Figure 1, the tail vapour of existing Thermal Power Station, a part enters in the atmosphere, and a part forms condensed water, and inflow is much larger than waste water withdrawal amount, and tail vapour utilization ratio is very low.
As shown in Figure 2, at condensing tower 3 positioned inside multi-stage condensing water collectors 13, condensate collector is every one of certain altitude peace, edge at condensing tower 3, have the water outlet 18 of a plurality of condensate collectors, be provided with catch basin 7 at each water outlet place, the bottom margin of every grade of catch basin is equipped with drain valve 9, the outlet of every grade of drain valve is connected with penstock 10 respectively, lowest part at penstock is equipped with hydroelectric power unit 19, the tail water mouth place of hydroelectric power unit is provided with draft tube 8, and the end of draft tube is provided with condensed water clarifier-tank 11; The waste steam of discharging through steam turbine power generation unit 2 passes condensate collector 13 step by step through condensing tower 3, the condensed water of collecting in the condensate collectors at different levels 6 is drained into catch basin 7 at the corresponding levels respectively, form the water level 12 of multistage different heights, water level potential energy to rudimentary, is carried out the ladder-type hydroelectric power by senior then.Tail water after the ladder-type hydroelectric power drains into condensed water clarifier-tank 11 through draft tube 8, carries out purified treatment again, forms pure distilled water 23.Again the mineral substance filter layer 21 of pure distilled water through mineralizer 20 filtered, absorb mineral matter nutritional, output mineral substance potable water 22.
