Water vapor extracted from the brown coal can be supplied to a power plant for use after being condensed and recycled by the condensing system disclosed by the utility model, so that a water resource shortage problem in most of China regions can be effectively solved.
Description
Technical field
The utility model relates to a kind of condenser system, particularly relates to a kind of condensation and reclaim the condenser system of brown moisture in coal.
Background technology
Water resource is the most critical resource of human being's production life, and China is a country that drought and water shortage is serious.Freshwater resources total amount is 28000 billion cubic meters, accounts for 6% of global water resources, is only second to Brazil, Russia and Canadian, occupy the 4th, the world, but only have per capita 2200 cubic metres, and be only 1/4 of world average level.Therefore, using water wisely, recycles various water resources and seems particularly important.
China's industrial water consumption increases year by year, and particularly some big power stations need to expend great lot of water resources.China's industrial water consumption increases year by year, and particularly some big power stations need to expend great lot of water resources.Power plant burns in boiler with fuel such as coals, heats high steam and promotes steam turbine generator generating, and high steam is finished and wanted rapid condensation after merit in steam turbine generator is water, could allow steam below constantly enter steam turbine generator and do work.In order to be water by exhaust steam rapid condensation, just adopt the cooling mode of cooling water, the general water yield will reach 50 times to 60 times of quantity of steam.These cooling waters recycle, and because water temperature is out higher, its evaporation capacity is also very large, though adopt now various water-saving modes, or cooling water can not be reduced to zero.So power plant, especially a coal-burning power plant.The consumption of water is huge.
And China's lignite resource is compared with horn of plenty, and many places are in water-deficient area, and water resource is the key factor of restriction regional development.Utilizing the high feature of the moisture of brown coal own, from coal, fetch water, for power plant, is the generation technology that more preferably " water saving " economizes on coal again.Therefore be necessary to carry out the technical research of brown coal water lift recovery, and carry out project demonstration.
At present, the dry technology of brown coal is had to pertinent literature report, but the steam being evaporated after brown coal drying mixes direct emptying process with air, cause the waste of great lot of water resources.
Utility model content
The purpose of this utility model is to provide a kind of condensation to reclaim the condenser system of brown moisture in coal.
The purpose of this utility model is implemented by following technical scheme, the condenser system of brown moisture in coal is reclaimed in a kind of condensation, it comprises air-introduced machine, condensing unit, condensate pump, cistern, recirculated water baffle-box, water circulating pump and air cooling heat radiator, the outlet of described air-introduced machine is connected with the air inlet of condensing unit, the recycle-water outlet of described condensing unit is connected with the water inlet of described condensate pump, and the delivery port of described condensate pump is connected with the water inlet of described cistern; The delivery port of described recirculated water baffle-box is connected with the water inlet of described water circulating pump, the delivery port of described water circulating pump is connected with the condensing water inlet of described condensing unit, the condensation-water drain of described condensing unit is connected with the water inlet of described air cooling heat radiator, the delivery port of described air cooling heat radiator is connected with the water return outlet of described recirculated water baffle-box, and described air cooling heat radiator adopts mechanical-draft cooling tower cooling.
Described condensing unit is condenser.Condensing unit adopts surface-type heat exchanger, pressurized operation, and heat exchanger is provided with evacuation port, for discharging the incondensable gas of heat exchanger.
Mist by the water vapour extracting in brown coal and air enters condenser after air-introduced machine boosts; The recirculated cooling water that carrys out self-circulating water baffle-box flows into condenser; The Mixed Gas Condensation heat exchange of recirculated cooling water and water vapour and air, a large amount of steam are cooled, and the incondensable gases such as air carry a small amount of steam and enter atmosphere; Recirculated cooling water after heat exchange returns to recirculated water baffle-box after flowing into air cooling heat radiator heat exchange, recycles; The recovery of brown moisture in coal delivered to cistern and completes by condensed condensate liquid through condensate pump.
The recycle-water rate of condensing unit and condensation temperature and to enter the oxygen content of mist of condenser relevant.In oxygen content one timing, condensation temperature is lower, and mist is separated out the water yield can be more, and recycle-water rate is higher.And mist oxygen content is lower, its water capacity is larger, and incondensable gas amount is fewer, in the time being cooled to same temperature, separates out the water yield more, and recycle-water rate is higher.The water that condensation is reclaimed, boosts through pump, is delivered to speciality of hydroelectric power engineering construction and regulates cistern, after processing, uses.
The utility model has the advantage of, (1) can be used by electric power supply plant after the utility model system condensing reclaims from the steam extracting brown coal, can effectively solve China's most area shortage of water resources problem; (2) raw material brown coal total moisture is down to 12% by 39.5%, the moisture rate of recovery is by 80%, annual utilization hours is by 6728h, it is 54.5 ten thousand tons that two unit design years are reclaimed the water yield, can supply 49.5 ten thousand tons of water that power plant desulphurization system expends every year, also can, for many for 50,000 tons of water of major project, reduce major project water consumption 5% left and right every year.
Accompanying drawing explanation
Fig. 1 is the condenser system schematic diagram that brown moisture in coal is reclaimed in a kind of condensation.
Air-introduced machine 1, condenser 2, condensate pump 3, cistern 4, recirculated water baffle-box 5, water circulating pump 6, air cooling heat radiator 7.
The specific embodiment:
Embodiment 1: the condenser system of brown moisture in coal is reclaimed in a kind of condensation, it comprises air-introduced machine 1, condenser 2, condensate pump 3, cistern 4, recirculated water baffle-box 5, water circulating pump 6 and air cooling heat radiator 7, the outlet of air-introduced machine 1 is connected with the air inlet of condenser 2, the recycle-water outlet of condenser 2 is connected with the water inlet of condensate pump 3, and the delivery port of condensate pump 3 is connected with the water inlet of cistern 4; The delivery port of recirculated water baffle-box 5 is connected with the water inlet of water circulating pump 6, the delivery port of water circulating pump 6 is connected with the condensing water inlet of condenser 2, the condensation-water drain of condenser 2 is connected with the water inlet of air cooling heat radiator 7, and the delivery port of air cooling heat radiator 7 is connected with the water return outlet of recirculated water baffle-box 5.
