Abstract
A sea water desalination plant utilizing the waste heat of electric power plant includes an existent turbine generator equipment, and is characterized by that the condenser of said equipment is respectively connected wtih water pump and dilatancy separator via valves, the dilatancy separator is connected with steam condenser through the pipeline, and its water-jet air-pumping device is respectively connected with dilatancy separator and steam condenser via valves, and the pump is connnected with steam condenser and water-jet air-pumping device respectively via valves. Said invention fully utilizes the waste heat of electric power plant so as to reduce cost for producing fresh water hy using sea-water and reduce thermal pollution to environment.
Description
The present invention relates to a kind of sea water desalinating plant, particularly relate to a kind of device that utilizes Space Heating for Waste Heat of Power Plant to carry out sea water desaltination.
Have a kind ofly to make the seawater flash vaporization and produce the device of fresh water in multiple sea water desalinating plant, wherein having heaters has decompression member again.The subject matter of using this device to produce the fresh water existence is that consumption of calorie is many, so cost is higher.On the other hand, the applicant notices, a large amount of heats water that is cooled is taken away and is wasted in the water vapor backheat circulation in the power station.
The purpose of this invention is to provide a kind of device that utilizes Space Heating for Waste Heat of Power Plant to carry out sea water desaltination, it can solve the problems referred to above of existing sea water desalinating plant and power station wasted heat.
A kind of device that utilizes Space Heating for Waste Heat of Power Plant to carry out sea water desaltination, comprise an existing steam-turbine power plant, the condenser that it is characterized in that this equipment is connected with the dilatation separator with water pump by valve respectively, the dilatation separator is connected with vapor condenser by pipeline, water jet air ejector is connected with vapor condenser with the dilatation separator respectively by valve, and pump is connected with water jet air ejector with vapor condenser respectively by valve.
Device of the present invention has made full use of the used heat in power station, has reduced the cost of being produced fresh water by seawater, has also reduced the thermal pollution to environment.
Below by embodiment and description of drawings the present invention.
Accompanying drawing is a structural representation of the present invention.
The inventive system comprises an existing steam-turbine power plant, it has a boiler 12, the steam that is produced by boiler 12 enters steam turbine 13 through pipeline, generator 14 generatings that the work done drive is connected with steam turbine 13, steam turbine 13 also is connected with condenser 15, and steam turbine 12 is to condenser 15 steam discharges, and the water recovery heat release becomes water, this water is carried through pipeline and is returned boiler 12, and this pipeline is connected with condenser water pump 7, low pressure heater 8, deoxygenator 9, pump 10 and high pressure heater 11 successively.Water pump 6 is connected on the condenser 15, and it can be input into seawater in the condenser 15, so that absorb steam turbine 13 steam discharge liberated heats, the temperature of seawater is raise about 20 ℃.Seawater after the heat absorption enters the dilatation separator 1 that is connected with condenser 15 through valve along pipeline, and the latter connects a water jet air ejector 2, and it can make the absolute pressure of dilatation separator 1 equal saturation pressure under the environment seawater temperature.Therefore the seawater that heats up of heat absorption moment of entering behind the dilatation separator 1 is in the superheated water state, is a unsure state.After flash distillation, about 3.6% evaporation of seawater becomes water vapor, and remaining is saturated seawater.Dilatation separator 1 is in a high position, and seawater wherein enters following seawater pond 4 by the road; The mass dryness fraction after gas-water separation of steam wherein can reach 99.5%, enters the vapor condenser 3 that is connected with dilatation separator 1 by the road, and the level pressure condensation heat becomes condensed water, becomes quality fresh water preferably, and the pond is stand-by with fixed attention along the pipeline inflow through valve again for the latter.Pump 5 connects vapor condenser 3 and water jet air ejector 2 by pipeline, and it can be transported to seawater in vapor condenser 3 and the water jet air ejector 2, and seawater also can be returned in the seawater pond by vapor condenser 3 and water jet air ejector 2 by another pipeline.Pump 5 is the unique power consumption parts of this device for realizing that the sea water desaltination purpose is set up.
The water vapor backheat circulation in power station produces the 6MW electric energy, water pump 6 is delivered to condenser 15 with the seawater of 1000t/h, water temperature raises 20 ℃, absorb 23.2MW heat energy, enter dilatation separator 1 back and produce the 36t/h water vapor, condense into the condensed water of 36t/h again through vapor condenser 3, pump 5 carries the 900t/h seawater respectively to water jet air ejector 2 and distiller 3 power as the device running, and power is 100kw.Pump 6 is the existing equipment in the circulation of water vapor backheat.
Cost-effectiveness analysis: producing the fresh water ability in the present embodiment is 36t/h, and consumed power is 100kw.Since this electric energy be heat power plant inside from electricity consumption, valency calculates at cost, generally should be 0.3 yuan/kwh, so produce the fresh water cost is: 0.83 yuan/t.Method for desalting seawater is a lot, and its cost mostly is 14 yuan/t.The present invention utilizes used heat so cost is very low and to produce the fresh water ability bigger.As adopt present method in a 600MW power plant or heat power plant, then it is produced the fresh water ability and can reach 3600t/h, can accumulate every year to produce fresh water and reach 3,100 ten thousand tons, possesses the ability of scale production, obviously has promotional value.
