Abstract
The utility model relates to a spiral coil pipe type steam-water heat exchanger which is composed of an upper seal head shell body and a lower seal head. A water outlet and a water inlet are respectively arranged on an upper and lower seal heads, and a steam inlet and a condensed water outlet are respectively arranged on the upper and lower parts of the shell body. The utility model is characterized in that an upper and lower tube plates are respectively arranged on the steam inlet and the lower part of the condensed water outlet, and 10 to 1000 roots of spiral coils are arranged between the tube plates. The utility model has the advantages of small size and excellent performance.
Description
The utility model relates to heat exchanger, and a kind of spiral coil steam water heat exchanger is provided especially.
At present the most common steam water heat exchanger is generally tubular structure, and heat exchange area is little, and volume is big and heavy, and condensate water forms barrier film equably attached on the tube wall, overslaugh the heat exchange of carbonated drink; In addition, the shell and tube heat exchanger tube does not have self-compensating ability, changes under the condition of work in frequent heat, cold conditions, very easily causes the damage of parts.Also once occurred return pipe formula steam water heat exchanger on the market, and though can increase heat exchange area, certain self compensation ability was arranged also, steam condensate still forms barrier film on tube wall, and heat exchange is not in good state.
The purpose of this utility model is to provide the steam water heat exchanger of the small and exquisite and superior performance of a kind of volume, i.e. spiral coil steam water heat exchanger.
The utility model provides a kind of spiral coil steam water heat exchanger, by upper cover (1) housing (4), low head (6) is formed, added water out (2), being added water inlet (5) is sub-packed on the low head (1), steam inlet (12) and condensate water outlet (8) are divided into housing (4) top and the bottom, it is characterized in that: on the steam inlet (12), be arranged with lower perforated plate (13) under the condensate water outlet (8), be equiped with 10-1000 root spiral coil (9) between tube sheet (13), spiral coil (9) has the inclination angle of 30-50 degree.
Heat transfer coefficient is an important technology economic indicator weighing the good and bad degree of heat exchanger performance.The hot aqueous medium is flowed in spiral coil with high flow velocities in the pipe, because action of centrifugal force produces additional circulation, makes fluid be strengthened heat exchange by acute row disturbance.Managing outer medium is steam, because the design feature of coil pipe, steam is in pearl heat exchange state on most of heat exchange surface.Heat exchange element is a copper tube, and very high thermal conductivity factor is arranged.Because these factors make heat exchanger that higher heat transfer coefficient be arranged, again by arranging heat exchange surface to improve the heat exchange effect significantly rightly.
With reference to the accompanying drawings the technical solution of the utility model is described.
Fig. 1 is the version and the partial sectional view of heat exchanger.
Embodiment is the heat exchange surface be made up of many copper spiral coils (9) of the critical piece of heat exchanger as seen from the figure.Coil pipe (9) two ends are separately fixed on the tube sheet (13), the form that fixing means adopts expanded joint and welding to combine.Before the welding pipeline section of coil pipe (9) end 3 millimeters long is removed the limit, the garden loop section of removing the place, limit is close on the tube sheet (13), then the garden being encircled edge joint weld is connected on the tube sheet (13), tube sheet (13) is a kind of composite members, on surface of steel plate, post the copper coin of 3 millimeters thick, can guarantee welding quality better like this, also can adopt another kind of scheme, that is exactly only to adopt a kind of special welding rod that copper pipe and steel tube sheet are welded together with the steel tube sheet, the self compensation ability of coil pipe (9) is better, only produce very little thrust in hot lower coil pipe (9) end and tube sheet (13) junction, this has just improved the operational reliability of heat exchanger.Require coil pipe (13) part that 45 ° of degree inclination angles are arranged simultaneously, so just can impel the major part at coil pipe position to be in pearl heat release state thereby to have improved heat-transfer effect at the heat-transfer area of steam side.
Steam inlet (12) has been located a steam baffle (11), and this directly washes away coil pipe (9) straight section for fear of high velocity vapor and partly causes and damage and be provided with.Baffle plate is led steam vent on (11), steam is full of coil pipe (9) and locates each space by leading between steam vent and pipe the space, and heat exchange takes place with coil pipe (9) surface and gradually cooling become condensate water, flow out by condensate outlet (8) subsequently, being added water goes into heat exchanger by import (5), leaves heat exchanger by being heated water out (2) after process coil pipe (9) is heated to predetermined temperature.
Claims (5)
1, a kind of spiral coil steam water heat exchanger, by upper cover (1) housing (4), low head (6) is formed, added water out (2), being added water inlet (5) is sub-packed on the low head (1), and steam inlet (12) and condensate water outlet (8) are divided into housing (4) top and the bottom, it is characterized in that: on the steam inlet (12), be arranged with lower perforated plate (13) under the condensate water outlet (8), be equiped with 10-1000 root spiral coil (9) between tube sheet (13).
2, by the described spiral coil steam water heat exchanger of claim 1, it is characterized in that: spiral coil (9) has the inclination angle of 30-50 degree.
3, by claim 1,2 described spiral coil steam water heat exchangers, it is characterized in that: tube sheet (13) is composited with copper coin and steel plate.
4, by claim 1,2 described spiral coil steam water heat exchangers is characterized in that, locate the steam baffle (11) that a band is led steam vent over against steam inlet (12).
5, by the described spiral coil steam water heat exchanger of claim 3, it is characterized in that: locate the steam baffle (11) that a band is led steam vent over against steam inlet (12).
