Abstract
The utility model discloses an aluminum-plate-fin type turbine generator air condenser which comprises an air side flow path and an air condensing side flow path. The air side flow patch has an air side pin, and the air condensing side flow patch has a water side fin. The condenser is characterized in that the height of the air side fin is 12-30mm, and the height of the air condensing side fin is 2-6mm which conquers the disadvantages usually existed in the air condensing system devices of the current technique such as bulk size and heavy weight, can be widely adopted in newly built plants or innovated plants.
Description
Technical field:
The utility model belongs to the cooling technology field, specifically relates to a kind of wing formula steam turbine generator aerial condenser.
Background technology:
At present, the unit (being commonly referred to steam power plant) that has many use steam turbines to be used as power to generate electricity in China.These generating sets have a common technical process, that is: high steam is after steam turbine expands acting, and the water cooling that is cooled under a negative pressure becomes the low pressure cold lime set, with high-pressure hydraulic pump these low pressure cold lime sets is returned boiler again.Therefore, in low-pressure steam is cooled process, consume a large amount of cooling waters.
At this shortcoming that this type of device will consume a large amount of cooling waters, especially in areas of serious, a kind of technology (ACC) that adopts air directly to come the condensation low-pressure steam is extensively adopted by domestic and international new power plant construction.China also use this technology newly-built 300,000 kilowatts to 600,000 kilowatts power plant.
Because the quantity of steam of steam turbine is very big, especially in summer, atmospheric temperature is very high, guaranteeing that the steam condensing pressure does not raise, and heat transfer temperature difference reduces under a lot of situations, become liquid to these exhaust steam total condensation, and the heat exchange amount and the heat exchange area of heat exchanger are all considerable.At present, the steel finned formula heat exchanger that is widely adopted, though its efficient is higher, its heat exchanger volume, weight, floor space and space are much bigger during all than original employing water-cooled.When newly founding the factory, often need to mark specially a zone, build a condensing factory and realize this technical process; When modernizing and expanding the existing factory, most of power plant is difficult to adopt because of the deficiency in floor area and space.Volume, the weight that how to reduce the aerial condenser system and device is the target that this technology further develops.
Summary of the invention:
The purpose of this utility model is to provide a seed wing formula steam turbine generator air cooling condenser, can overcome that the ubiquitous volume of aerial condenser system and device in the prior art is big, the shortcoming of Heavy Weight.
For achieving the above object, the technical solution adopted in the utility model is as follows: a kind of aluminum plate-fin type steam turbine generator aerial condenser, comprise air side stream and condensing effluent road, the air side stream has air side fins, condensing effluent road has water side fin, it is characterized in that: described air side fins height is 12～30mm, and condensing side fin height is 2～6mm.
The ratio of the port number on the port number of air side stream and condensing effluent road is 2: 10.
Adopt the utility model condenser device of technique scheme to compare with existing steel finned formula condenser arrangement, it is little to have a volume, and lightweight advantage can be widely adopted in grassroot project with in modernizing and expanding the existing factory.
Description of drawings:
Fig. 1 is the utility model example structure schematic diagram.
The specific embodiment:
Referring to accompanying drawing.Aluminum plate-fin type steam turbine generator aerial condenser of the present utility model comprises air side stream 1 and condensing effluent road 2.Air side stream 1 has air side fins, and condensing effluent road has condensing side fin 3.The air side fins height is 12～30mm, and condensing side fin height is 2～6mm.The ratio of passage 4 quantity on the passage of air side stream and condensing effluent road is 2: 10.The air side flow path length is very short, and condensing effluent road length depends on the size of condensing side manufacturing cell windward side, equals the height of windward side in principle.Described air-flow direction becomes 90 degree with the condensing flow direction, promptly this condenser is the cross-current type single-pass exchanger.
Fin material all adopts high-intensity aluminium alloy, not only has the advantage of intensity height, corrosion-resistant, long service life, and because the thermal conductivity factor of aluminium alloy is big, makes that the heat transfer efficiency of this condenser is better than steel heat exchanger heat-transfer effect.The fin material trade mark is 3003-O.
The condenser of present embodiment all adopts sheet type design of part form, so heat exchanger is quite compact.Have in every cubic metre the volume up to 915 square metres of heat exchange areas, and weight only is 850kg/m
