Abstract
The utility model discloses a jacket for a plate type heat exchanger. The jacket is lined at an angular hole of a compaction plate in the plate type heat exchanger and is characterized by being made of polyfluortetraethylene and matched with the angular hole of the compaction plate in shape. The utility model has simple structural design, simple processing and lower cost in comparison with a metal jacket. By replacing the traditional rubber and metal jacket with the jacket made of polyfluortetraethylene, the utility model overcomes the defects of material and processing, improves the corrosion resistance and high temperature resistance during use, greatly prolongs the service life of the plate type heat exchanger and particularly has special effects on chemical media with strong corrosion property.
Description
Technical field:
The utility model relates to a kind of chuck, is specifically related to a kind of safe and reliable plate type heat exchanger chuck.
Background technology:
Plate type heat exchanger is a kind of new type high efficient heat exchanger that is formed by a series of sheet metal closed assemblies with certain bellows-shaped.Form the thin rectangular shape passage between the various plates, carry out exchange heat by plate.It is compared with the shell-and-tube heat exchanger of routine, and under identical flow resistance and pump power consumption situation, its heat transfer coefficient will exceed a lot, and the trend that replaces shell-and-tube heat exchanger is arranged in applicable scope.
The ideal equipment that plate type heat exchanger carries out heat exchange as a kind of liquid-liquid, liquid-vapour.It has that heat exchange efficiency height, heat loss are little, advantages of compact and light structure, floor space are little, install clean make things convenient for, be widely used, characteristics such as long service life.Under the uniform pressure damaed cordition, its heat transfer coefficient is than the high 3-5 of pipe heat exchanger times, and floor space is 1/3rd of a pipe heat exchanger, and heat recovery rate can be up to more than 90%.Plate type heat exchanger is widely used in industries such as metallurgy, oil, chemical industry, food, pharmacy, boats and ships, weaving, papermaking, is the good equipment of purposes such as heating, cooling, recuperation of heat, quick sterilization.
But the pressure strip of board-like heat exchanger is generally by the carbon steel manufacturing, in application, often run into the extremely strong medium of various corrosivity, traditional way is to solve the problem that is corroded at place, hole, pressure strip angle corresponding rubber bushing of lining or metal chuck, but the temperature tolerance of rubber bushing is relatively poor in actual the use, easily aging, service life is shorter, often needs to change.And metal lining needs welding, and the stress that welding produces is concentrated, and makes corrosion resistance reduce, and cracking causes leakage easily simultaneously.Cause enterprise's stop production to overhaul, increased maintenance cost, bring unnecessary loss to enterprise.
The utility model content:
The utility model at the pressure strip of present plate type heat exchanger generally by the carbon steel manufacturing, in application, often run into the extremely strong medium of various corrosivity, and light is difficult to solve the problem that is corroded at place, hole, pressure strip angle corresponding rubber bushing of lining or metal lining, cause a series of problems such as cracking, leakage of plate type heat exchanger equipment easily, carry out rational improvement, thereby reached the purpose that reduces cost and improve practicality.
In order to achieve the above object, the utility model adopts following technical scheme to realize:
A kind of plate type heat exchanger chuck, described chuck are lining in the pressure strip angle Kong Chu in the plate type heat exchanger;
Described chuck is the polytetrafluoroethylene (PTFE) chuck, and matches with place, hole, pressure strip angle shape.
This utility model, reasonable in design, processing is simple, and cost is lower than metal lining.After the chuck made from polytetrafluoroethylmaterial material substitutes original rubber, metal lining, overcome its material and added the shortcoming of processing technology aspect in man-hour, corrosion resistance, heat-resisting quantity have in use been improved, and prolonged service life of plate type heat exchanger greatly, it is effective especially especially some to be had a chemical medium of severe corrosive.
Description of drawings:
Further specify the utility model below in conjunction with the drawings and specific embodiments.
Fig. 1 is a kind of configuration diagram of utility model.
The specific embodiment:
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
Because the plate type heat exchanger in using at present mainly is made up of efficient heat transfer corrugated cardboard sheet and framework.Plate is clamped between fixed pressure plate and the movable pressure plate by bolt, has just constituted many runners in heat exchanger inside, uses rubber seal between plate and the plate.Plate forms with the compacting of high-quality corrosion resistant metal thin plate, and Si Jiaochong has the hole, angle for the medium turnover, and hanging hole is arranged up and down.The herringbone ripple can increase the disturbance of convection cell, makes fluid can reach turbulence state under low speed, obtains high heat-transfer effect.And the employing special construction, guarantee that two kinds of fluid media (medium)s can not go here and there Lou.
As shown in Figure 1, in a kind of plate type heat exchanger, the partial structurtes diagrammatic sketch at position, hole, pressure strip angle, comprising, chuck 1, fixed pressure plate 2, flange 3, gland flange 4, hole, angle 5, bolt 6.Chuck 1 is the polytetrafluoroethylene (PTFE) chuck of structure through special optimization, and as can be seen from Figure, described chuck is lining in the place, hole, pressure strip angle in the plate type heat exchanger and is the polytetrafluoroethylene (PTFE) chuck, and matches with place, hole, pressure strip angle shape.Can it be served as a contrast at 5 places, hole, angle of fixed pressure plate 2 according to conventional method for this reason, replace rubber bushing and metal lining in the tradition use.The effect of bolt 6 then is that fixed pressure plate 2 and flange 3 and gland flange 4 are connected and fixed.
This utility model, the special chuck by being made by polytetrafluoroethylmaterial material replaces rubber bushing and metal lining, not only in configuration aspects, can effectively match with place, seat, hole, pressure strip angle in the plate type heat exchanger, and it can perfectly be connected; And various high temperature fluids for flow through heat transferring plate and hole, angle, very strong corrosion resistance is arranged, thereby fundamentally solved in the plate type heat exchanger, because the lining poor heat resistance of rubber material, the easy aging weak point in service life that reaches, and the concentrated corrosion resistance that makes of the lining welding stress of metal material reduces, to such an extent as to high temperature fluid has corroded the pressure strip that carbon steel material is made, caused the cracking of equipment to leak, increase the problem of the maintenance cost of enterprise.And as the chuck of the stronger polytetrafluoroethylene (PTFE) material of durability, prolonged the service life of plate type heat exchanger greatly, reduce producer and taken the trouble of stop production to overhaul frequently, thereby increased production efficiency effectively, effective especially for the chemical medium that severe corrosive is arranged.
More than show and described basic principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
