Abstract
Plate type graphite plastic heat exchanger, heat transferring plate is to mix mold pressing in proportion with plastics, graphite powder, chopped carbon fiber to form, plane sealing structure on this heat exchanger employing heat transferring plate and special seal sealing, has heat transferring plate mechanical strength height, the equipment excellent anti-corrosion performance, advantages such as good seal performance can extensively be suitable for the occasion of the cold and hot medium indirect heat exchange of corrosivity, have bigger implementary value.
Description
The invention belongs to heat exchanger, plate type graphite plastic heat exchanger especially is applicable to the occasion of the cold and hot medium indirect heat exchange of corrosivity.
Before the present invention made, normally used plate type heat exchanger was panel metal heat exchanger and plate graphitic heat-exchanger.Plate type heat exchanger is made up of one group of heat transferring plate, leaves the hole, angle on the plate and supplies the cold fluid and hot fluid of heat exchange to pass through.The heat transferring plate assembly is contained between two block pressur plates, and fixes with fastening bolt, places the gasket seal of hole, salable angle and fluid passage between two heat transferring plates.The heat transferring plate of panel metal heat exchanger adopts general steel plate easily by dielectric corrosion, adopts corrosion resistant plate also easily by the dielectric corrosion of fluoride ion, adopts its decay resistance of titanium plate splendid, but costs an arm and a leg.The appearance of plate graphitic heat-exchanger (patent No. 89214112.3) has tentatively solved the etching problem of heat transferring plate, because the mechanical strength of heat transferring plate is low slightly, so the equipment working pressure is not high, and the not corrosion of powerful oxidation corrosion resistance medium.Existing two class plate type heat exchangers all adopt the rubber seal sealing, and sealing effectiveness is not too satisfied, and heat exchanger easily produces and leaks under the gap operating condition or after long-term the use.
The objective of the invention is to overcome the deficiency that prior art exists, provide a kind of heat transferring plate mechanical strength height, excellent anti-corrosion performance, the plate type graphite plastic heat exchanger of equipment good seal performance.
Plate type graphite plastic heat exchanger, include the flanged adapter of plastic lining (1), fastening bolt (2), nut (3), metal platen (4), plastics lining board (5), heat transferring plate (6), seal (7), heat transferring plate (6) is by heat transfer structure (8), hermetically-sealed construction (9), hole, angle (10) is formed, the key component of heat transferring plate (6) is plastics and graphite powder, plastics and graphite powder weight percentage ratio are 10: 90 to 30: 70, its auxiliary reinforcement chopped carbon fiber weight percentage is 2～20% of heat transferring plate (a 6) material total amount, the heat transfer structure (8) of heat transferring plate (6) can adopt oblique ripple or herringbone ripple or semi-spherical protrusions (warty) structure, with heat-transfer effect that improves heat transferring plate (6) and the rigidity that strengthens heat transferring plate (6), the hermetically-sealed construction (9) of heat transferring plate (6) adopts plane sealing structure or the structure of 1～5 sealing lines is set in the plane, the flanged adapter of plastic lining (1) has four, be respectively (11), (12), (13), (14), (11), (12) be entrance sleeve, (13), (14) be discharge connection.Heat transferring plate (6) key component plastics can be polyolefin plastics or fluoroplastics.Plate type graphite plastic heat exchanger comprises three or more heat transferring plate (6), seal (7) between adjacent two heat transferring plates (6) can be liquid sealant or flexible graphite gasket or expanded ptfe band, to reach the reliable sealing purpose.
Advantage of the present invention: (1) heat transferring plate mechanical strength height; (2) excellent anti-corrosion performance of heat transferring plate, especially graphite fluoroplastics heat transferring plate almost can anti-any medium corrosion, comprise strong oxidizing property medium such as the concentrated sulfuric acid, chromic acid etc.; (3) heat exchanger has adopted plane sealing structure and the special seal of three classes, except reaching the corrosion resistance requirement, has also improved the sealing property of equipment, guarantees that plate type graphite plastic heat exchanger does not leak under various use occasions.
Below in conjunction with accompanying drawing embodiment is described further:
Fig. 1 is the plate type graphite plastic heat exchanger structural representation.
The wherein flanged adapter of 1-polypropylene plastics lining, 11-entrance sleeve, 12-entrance sleeve, 13-discharge connection, 14-discharge connection, 2-fastening bolt, 3-nut, 4-metal platen, 5-polypropylene plastics liner plate, 6-heat transferring plate, 7-seal.
Fig. 2 is the heat transferring plate structural representation.
8-heat transfer structure wherein, 9-hermetically-sealed construction, hole, 10-angle.
Embodiment of the present invention and operation principle are: plate type graphite plastic heat exchanger, include the flanged adapter of plastic lining (1), fastening bolt (2), nut (3), metal platen (4), plastic lining (5), heat transferring plate (6), seal (7), heat transferring plate (6) is by heat transfer structure (8), hermetically-sealed construction (9), hole, angle (10) is formed, the key component of heat transferring plate (6) is plastics and graphite powder, plastics and graphite powder weight percentage ratio are 15: 85, heat transferring plate (6) key component plastics are polypropylene plastics, its auxiliary reinforcement chopped carbon fiber weight percentage is 3% of heat transferring plate (a 6) material total amount, material evenly mixes the back extruding pelletization, the once molding formed heat transferring plate (6) that obtains in mould, the heat transfer structure (8) of heat transferring plate (6) is the herringbone ripple struction, with heat-transfer effect that improves heat transferring plate (6) and the rigidity that strengthens heat transferring plate (6); The hermetically-sealed construction (9) of heat transferring plate (6) is a plane sealing structure, plate type graphite plastic heat exchanger comprises 20 heat transferring plates (6), seal (7) between adjacent two heat transferring plates (6) is a teflon seal tape, to reach the reliable sealing purpose.Shown in figure (1), cold fluid and hot fluid is respectively by the entrance sleeve (11) of the flanged adapter of the plastic lining of this heat exchanger (1), (12) flow into, discharge connection (13) by the flanged adapter of plastic lining (1), (14) flow out this heat exchanger, because the herringbone heat transfer structure (8) of the heat transferring plate (6) of plate type graphite plastic heat exchanger makes cold fluid and hot fluid form the purpose that strong turbulent flow reaches heat transfer in the runner separately of heat transferring plate (6) both sides, improved heat-transfer effect, general heat-transfer effect is 85～95%, the heat transferring plate (6) that cold and hot medium contacted simultaneously, the flanged adapter of plastic lining (1), seal (7) corrosion resistance and good that constitutes by teflon seal tape, thus reached the corrosion-resistant requirement of whole equipment.
Board-like graphite polypropylene plastics heat exchanger assembling technology is: earlier the flanged adapters of four root polypropylene plastic linings (1) are welded on metal platen (4) and the polypropylene plastics liner plate (5), 20 heat transferring plates (6) are placed between metal platen (4) and the polypropylene plastics liner plate (5), glue on the sealing surface between two heat transferring plates (6) and put expanded ptfe band (7), use fastening bolt (2) and nut (3) at last metal platen (4), polypropylene plastics liner plate (5), heat transferring plate (6) and expanded ptfe band (7) clamp becomes board-like graphite polypropylene plastics heat exchanger.
