Abstract
The utility model relates to a corrugated pipe heat net heater, which is designed for solving the problem that the heating exchanging efficiency of a traditional straight pipe heat exchanger is low. A shell pass cylinder part provided with a steam inlet and a condensation outlet is designed with a large caliber to enable the cylinder volume to be enlarged, thereby reducing the steam flow speed to enable fluid homogeneously to enter into pipe bundles. A flow guiding ring cylinder for buffering and eliminating a stagnation zone is provided at the steam inlet, thereby reducing the erosion action on the heat exchange pipe bundles caused by the steam at the inlet. In addition, the traditional straight pipe heat exchange pipe can be replaced by the corrugated heat exchange pipe to enable the heat transfer efficiency to be improved greatly. The utility model has good characteristics of high heat transfer coefficient, no scale formation, high cost performance and long service life.
Description
Technical field
The utility model relates to the heat transfer technology field, is a kind of bellows heat exchangers for district heating concretely.
Background technology
At present, the traditional straight tubular heat exchanger of the many employings of the heat exchangers for district heating in power plant's heating system, through facts have proved, the art designs of this heat exchanger has defective, causes its heat transfer efficiency not high, therefore, needs a kind of novel heat exchangers for district heating badly and replaces.
Summary of the invention
The purpose of this utility model just provides a kind of bellows heat exchangers for district heating, and this heat exchangers for district heating has energy-efficient characteristics.
The utility model is achieved in that
Shell-side cylinder is provided with heavy caliber and small-bore two parts, on the heavy caliber shell-side cylinder, is provided with steam inlet and condensation outlet, at the steam inlet place, is provided with the guide ring tube that is communicated with shell-side cylinder.In shell-side cylinder, be provided with the corrugated tube bundle.
Operation principle of the present utility model is as follows:
The shell-side cylinder that the inventor will be provided with steam inlet and condensation outlet partly is made as heavy caliber, and the cylindrical shell volume in this part is enlarged, and so just can reduce steam flow rate, prolongs heat-exchange time.At the steam inlet place, also be provided with the guide ring tube that has buffering concurrently and eliminate the stagnant area, thereby can reduce the erosion effect of the steam heat exchanging tube bank of import department.
For improving the heat transfer efficiency of equipment, the inventor has replaced traditional straight tube heat exchanger tube with corrugated tube.Bellows is a kind of by tangent continuously inside and outside shape of big or small circular arc such as undulatory efficient enhanced tube, steam is when the heat exchanger tube surface condensation, because capillary effect makes condensate liquid drip along tube wall, can not form one deck liquid film at tube wall, can improve the outer heat transfer coefficient of pipe greatly, be that one-sided heat transfer coefficient is 3-5 a times of light pipe, this heat exchangers for district heating temperature difference is bigger simultaneously, under the thermal (temperature difference) stress effect, ripple is axially having dilatation, even a small amount of incrustation scale is arranged on the tube wall, also can come off with the flexible of pipe.Bellows itself has the temperature difference compensation ability simultaneously, adapts to big temperature difference operating mode.
The utility model possesses following good characteristics: 1. heat transfer coefficient height: for the outer steam condensation of this pipe, the operating mode of recirculated water cooling has invigoration effect preferably in the pipe, improves heat transfer coefficient in the pipe greatly.2. less scaling: fluid constantly washes away the heat exchange tube wall in the inside and outside strong disturbance of pipe, make tube wall less scaling, because the coefficient of expansion of metal is different with the nonmetallic coefficient of expansion, under the thermal (temperature difference) stress effect, ripple is axially having dilatation, even a small amount of incrustation scale is arranged on the tube wall, also can come off with the flexible of pipe.3. ratio of performance to price height: it only is 1/2 of light pipe that the corrugated tube heat exchanger of this pattern is compared area with common light pipe, and floor space also significantly reduces, and can save investment significantly.4. guide shell exchange heat pipe plays a very good protection, and prolongs the service life of equipment.
Description of drawings

Fig. 2 is a guide ring tube schematic diagram.
The specific embodiment
Describe in detail below in conjunction with drawings and Examples:
Shell-side cylinder 4 is arranged to the different two parts of bore, and the middle part is a heavy caliber, and two ends are small-bore.On heavy caliber shell-side cylinder 4, steam inlet N1 and N2 and condensation outlet N3 and N4 are set.At steam inlet N1 and N2 place, the guide ring tube 1 that is communicated with shell-side cylinder 4 small-bore ends is set.In shell-side cylinder 4, corrugated tube bundle group 3 and deflection plate 2 are set.
Steam enters shell-side cylinder 4 through import N1, N2 and guide ring tube 1, through deflection plate 2 bafflings, carries out heat exchange with tube bank group 3, after the condensation, is flowed out by outlet N3 and N4.The import N5 of tube side recirculated water on tube side housing 5 enters, and flowed out by outlet N6 after changing heating.
