Description

Novel tube bundle heat exchanger
Technical field
The utility model belongs to the heat-exchange apparatus technical field, is specifically related to a kind of tube bundle heat exchanger.
Background technology
Tube bundle heat exchanger belongs to heat transmission equipment at present commonly used, mainly by shell, heat-exchanging tube bundle and fixedly the dividing plate of heat-exchanging tube bundle form, heat-exchanging tube bundle joint direct and on the shell is connected, heat-exchanging tube bundle is easily damaged by workpiece or other article.Existing heat exchanger main part heat-exchanging tube bundle is made by metal materials such as nonmetallic materials such as graphite, pottery, glass and stainless steel, titanium, tantalum, zirconiums mostly, and wherein there are frangible, shortcomings such as volume big, poor heat conductivity in the heat exchanger of material manufacturings such as graphite, pottery, glass; And the heat exchanger price that metal materials such as titanium, tantalum, zirconium are made is too expensive, and use cost is higher relatively; The then hard to bear many Korrosionsmediums of stainless steel easily produce intercrystalline corrosion, and service life is not long.
Summary of the invention
The purpose of this utility model is provide a kind of heat-conductive characteristic excellence, heat exchanger materials chemical stability and cold and hot good stability, and there is not the new type heat exchanger of little seepage in the attachment weld place at many deficiencies of existing heat exchanger existence.
For achieving the above object, technical solutions of the utility model are as follows:
New type heat exchanger comprises shell that is provided with louvre and the heat-exchanging tube bundle group who is made up of some heat-exchanging tube bundles, be welded with the dividing plate of cross supporting frame and PP or PVDF material in the described shell, evenly distribute and the corresponding aperture of heat-exchanging tube bundle quantity on the described dividing plate, heat-exchanging tube bundle passes aperture and is fixed and does not contact mutually, heat-exchanging tube bundle group two ends are connected with two joints of cover top portion by protective jacket, and joint is connected with external pipe.
Louvre bore on the described shell is 50~70mm, and distance is 10~30mm between the Kong Yukong.Protective jacket is enclosed within on the heat exchanger tube group, will restrain group and joint and tighten together; Dividing plate plays stationary heat exchangers tube bank and makes that heat exchanger tube evenly distributes, non-touching effect; Dividing plate and cross supporting frame and outer cover of heat exchanger weld together, but heat exchanging device shell mechanism plays a part to support and strengthen.
Two joints on the described shell can be flange form sealing or the sealing of loose joint formula, and wherein the flange form sealing and fixing is on the link plate of heat exchanger top, and one section of link plate is stretched out in the sealing of loose joint formula; Two kinds of joints are selected to use according to actual needs, when whole heat exchanger is immersed in the tank liquor liquid level when following, must adopt loose joint formula seal nipple, in case that tank liquor leaks into Tube Sheet of Heat Exchanger is intrafascicular.
Described heat-exchanging tube bundle material adopts any among FEP, PFA, PTFA or the PVDF, and the tube bank bore can be selected any among 3.5mm, 4.5mm, 5mm, 6mm, the 8mm for use, and heat-exchanging tube bundle quantity is general to adopt a kind of in 37,61,91,127,169,217.
Described protective jacket is a FEP heat-shrink tube protective jacket, plays fastening heat-exchanging tube bundle group, is convenient to it and is connected with joint, and can prevent that heat exchanger tube from being damaged by workpiece or other article.
Described shell upper end is a link plate, is provided with fixing hole around the link plate, is used for heat exchanger is fixed.
Advantage of the present utility model is:
1, the utility model heat exchanger adopts the form of bundle of capillary tubes, can enlarge markedly the contact area of solution in heat exchanger and the groove; Heat exchanger tube adopts advanced powder metallurgical technique sintering to form, and has the thin characteristics of tube wall, has significantly improved heat conducting speed, thereby makes heat-conductive characteristic excellent more.
2, between heat exchanger tube group and joint, be provided with FEP heat-shrink tube protective jacket, both played fastening heat-exchanging tube bundle group, be convenient to the effect that it is connected with joint, can prevent that again heat exchanger tube from being damaged by workpiece or other article.
3, the utility model adopts advanced welding procedure to make the attachment weld compression strength between heat exchanger dividing plate and the tube bank reach 1.5MPa, and having solved in the traditional heat exchangers making needs to install the problem of fistulae because of there is little seepage in the attachment weld place.
4, the heat-exchanging tube bundle material adopts any among FEP, PFA, PTFA or the PVDF, above material belongs to chemical inert material, has extremely strong chemical stability and cold and hot stability, the applicable working temperature scope is-150~200 ℃, except that the fluorine under the high temperature, molten state alkali metal, chlorine trifluoride, hex, perfluorokerosene (PFK), almost can work in other All Medias, be stainless 20 to 30 times its service life in strong corrosive medium; In addition, because above material does not contain photosensitive gene, and tool also has excellent resistance to weathering.
5, because the heat-exchanging tube bundle material has well in song, can as required heat exchanger tube be made into the heat exchanger of various ways such as W type, L type, U type, O type, both improve the heat exchange area in the unit volume, can adapt to different working environments again.
