Description
Technical field
It the utility model is related to technical field of heat exchange, and in particular to it is cold to ward off condenser inside and outside a kind of installation spiral band
But manage.
Background technology
Condenser is the important cold source equipment in Turbo-generator Set, and condenser is situated between by being passed through cooling in cooling tube
Matter, turbine discharge is condensed into a kind of heat exchanger of water, also known as steam condenser, cooling medium can be water or air, concentrate solidifying
The condensate of vapour device bottom is sent to oxygen-eliminating device direction by condensate pump can be used as boiler feedwater.Some use river, lake water, reservoir
Water, seawater do the steam power plant of circulating cooling medium, after water quality is contaminated, aggravates Cooling Tubes of Condenser corrosion rate, make
Frequently revealed into condenser, have a strong impact on normal production, reduce generation load.Especially currently on the market many copper pipes as cold
But manage, easily caused to reveal by corrosion such as ammonium ion, sulfide, simultaneously because the rough easily attached microbial and various of copper pipe inwall
Dirt, substantially reduce the service life of copper pipe.Use the way that stainless steel tube is very applied economics instead, Large-scale machine set is not more using
The titanium tube got rusty is as cooling tube, although compact-sized, heat exchange efficiency is high, maintenance is simple and service life is grown, shortcoming is construction
Difficulty is big, and material price is expensive.
The water temperature of steam turbine cycle cooling water is typically between 20 DEG C -35 DEG C, the breeding of suitable algae and microorganism, circulation
Substantial amounts of moisture content is evaporated during water use, and the algae of cooling water constantly concentrates, the calcium bicarbonate concentration more and more higher in water,
Free carbon dioxide but constantly volatilizees, and makes Ca (HCO3)2It is decomposed into CaCO3And separate out and form incrustation scale.The serious shadow of carbonate deposit
The heat-transfer effect of metal has been rung, while algae makes cooling water circulation situation constantly deteriorate, if circulating cooling medium is air, air
In contain dirt body, using easily causing dust and dirt after the long period, after condenser copper tube inwall forms incrustation scale or dust and dirt, under heat transfer effect
Drop causes vacuum decay, and energy consumption rises, and generation load or cleaning during shutdown are reduced when serious.
Utility model content
The utility model provides a kind of the inside and outside of spiral band that install additional and wards off Cooling Tubes of Condenser, and cooling tube inside and outside wall is carried out
Enamel processing, a kind of spiral band of special construction of interpolation had both improved the service life of cooling tube, and and can automatic desludging is improved and changed
The thermal efficiency, while by strong disturbance border retention layer, the heat transfer of the maximum border retention layer of thermal resistance is effectively enhanced, so as to
Reach energy-conservation, the purpose of volume increase.
To achieve these goals, the technical solution adopted in the utility model is as follows：
A kind of the inside and outside of spiral band that install additional wards off Cooling Tubes of Condenser, including base tube, and the base tube inside and outside wall has enamel,
Spiral band is inserted with the base tube, the spiral band is provided with least one gear parallel to the base tube cross section
Plate, the baffle plate are provided with circular hole.
Preferably, the enamel thickness is 0.3-0.5mm.
Preferably, the spiral band and baffle plate use polytetrafluoroethylmaterial material, polytetrafluoroethylene (PTFE) high temperature resistant, corrosion resistant
Erosion, high lubrication, do not adhere to, excellent performance.
Preferably, the spiral band is perpendicular to the cross section of the base tube.
Preferably, the both ends of the spiral band with the both ends of the base tube by being welded and fixed.
Preferably, the length of the spiral band is less than the total length of the base tube.
Preferably, the width of the spiral band is less than the internal diameter of the base tube.
Preferably, the signal period tie length d of the spiral band is more than 20mm.
The beneficial effects of the utility model are shown：
1st, base tube inside and outside wall adheres to erosion-resisting enamel, can greatly extend the service life of cooling tube, prevent from circulating
Aqueous corrosion；
2nd, enamel surface is more smooth, plus the effect of spiral band, can reach and reduce incrustation scale, dust and dirt formation and automatic water-removing
Dirt, the effect of dust and dirt, the setting of baffle plate and circular hole also further reduce dust and dirt, avoid the fiber crops that each cleaning during shutdown is brought
It is tired.
3rd, it is stagnant effectively to enhance the maximum border of thermal resistance by strong disturbance border retention layer for the spiral band in base tube
The heat transfer of layer is stayed, enhances heat transfer effect, improves heat exchange efficiency, while the setting of circular hole can improve the turbulence level of fluid,
Improve heat exchange efficiency.
4th, compared to copper pipe, stainless steel tube, the cooling tube cost of this interior external enamel coating is lower, and service life is longer.
