Abstract
The utility model relates to a condenser with a stainless steel heat exchange tube with a spiral groove and high heat exchange performance, which is matched with a steam turbine in a thermal power plant to use. The utility model is composed of a housing in which a steam chamber is arranged. The upper side and the lower side of the steam chamber are respectively communicated with a steam inlet chamber and a water collecting tank. A water inlet chamber and a water outlet chamber are also arranged in the housing. A stainless steel heat exchange tube is arranged in the steam chamber. An arc-shaped spiral groove is arranged on the tube wall of the stainless steel heat exchange tube. The utility model has the characteristics of good heat transfer effect, strong corrosion resistance, low cost and compact integral structure.
Description
The utility model relates to a kind of being suitable for and disposes the helicla flute stainless steel heat exchanger tube condenser with high heat exchanger efficiency that uses with the thermal power plant steam turbine, is used for carrying out recycling and processing to the exhaust steam that steam turbine is discharged.
Condenser is one of the vitals in thermal power plant, the good and bad runnability that directly influences the power plant of it and other auxiliary device performance.The quality of condenser performance depends on the performance of heat exchanger tube in the condenser steam chest to a great extent, in order to improve exchange performance, existing mode is to adopt the high-quality tubing of good heat conductivity, be used as heat exchanger tube as copper pipe, this not only makes the cost of product improve greatly, and it is strong inadequately to select for use steel pipe also to exist corrosion resistance, the problem of copper pipe thickness of pipe wall.
Task of the present utility model is to avoid the deficiency of above-mentioned existence and the high-efficiency helical groove stainless steel heat exchanger tube that a kind of cost is low, performance is excellent condenser is provided.
Task of the present utility model is realized by following scheme: have housing 2, be provided with steam chest 17 in the housing, the upper and lower of steam chest is connected with air chamber 1 and header tank 7 respectively, in housing, also be provided with intake chamber 11 and water-supplying chamber 15, difference of the present utility model is that in steam chest 17 have installed stainless steel heat exchanger tube 14, and the tube wall of stainless steel heat exchanger tube is provided with the helicla flute 18 of arc.
By above-mentioned basic scheme, for further reducing the cost of heat exchanger tube, stainless steel heat exchanger tube 14 can be welded by the stainless steel band turnup, promptly adopts welded tube formula helicla flute stainless steel heat exchanger tube.
According to such scheme, main feature of the present utility model is to have adopted band spiral fluted stainless steel heat exchanger tube, compare with original light pipe, because the variation of structural pipe wall, forced-convection heat transfer thermal resistance in outer condensation heat transfer thermal resistance of pipe and the pipe is reduced greatly, and recirculated water forms spiral flow and boundary layer separation flow simultaneously in heat exchanger tube; The surface tension of condensate water outside pipe increases, thereby the convection current of heat exchanger tube and condensation heat transfer are strengthened, and improved its heat exchange performance greatly, and produced following good effect:
1, heat-transfer effect is good, compares with existing bare copper tube condenser, and heat transfer coefficient has improved more than 20%;
2, adopt stainless steel tube, various corrosion resistances such as the anti-steam heat spot corrosion of its shock resistance burn into, the corrosion of resistive connection dirt all have bigger enhancing, in addition, because the conversion of tubing and the relative attenuate of tube wall, not only can save material, reduce the cost, and can reduce the volume and weight of condenser, make its structure more compact;
3, less scaling in the pipe, can reduce wash number, and the utility model is low to the cycle water requirement, it is applied widely.
Fig. 1 is the structure chart of facing of an embodiment of the utility model.
Fig. 2 is the left view of an embodiment of the utility model.
Fig. 3 is the full sectional view of helicla flute stainless steel heat exchanger tube among embodiment of the utility model.
An embodiment of the present utility model such as Fig. 1,2, shown in 3, housing 2 with tubular sealing, be provided with steam chest 17 in the housing, welded tube formula single head helicla flute stainless steel heat exchanger tube 14 is installed in the steam chest, helicla flute 18 is an arc, outside on tube wall, being recessed in convex, it becomes tubulose by the continuous turnup of level and smooth stainless steel band, be welded into light pipe by tungsten electrode then, form through the extrusion process helicla flute, the tube sheet 12 at the two ends of stainless steel heat exchanger tube 14 and steam chest two ends is expanded joint mutually, in steam chest 17, also be installed on central dividing plate 6, the top of steam chest is connected with air chamber 1, the bottom of steam chest is connected with collector pipe 7 by bleeder pipe 8, the end tube sheet outside is arranged with intake chamber 11 and water-supplying chamber 15 by hydroecium dividing plate 13 in housing 2, water inlet pipe and water-supplying chamber be external cooling water inlet pipe 10 and cooling water outlet pipe 16 respectively, intake chamber 11 is connected with the stainless steel heat exchanger tube 14 of the latter half, the hydroecium 5 of other end setting in housing communicates with the stainless steel heat exchanger tube of the first half, the other end of the first half stainless steel heat exchanger tube communicates with water-supplying chamber 15, form the connection of intake chamber and water-supplying chamber thus, also can be provided with in the termination of housing 2 and to spy on port lid 4, the outer down either side of housing is installed on elasticity mounting 9, and the bleeding point 3 that is connected with steam chest.
