Description
Technical field
The utility model belongs to heat transmission equipment, specifically is exactly a kind of plate type heat exchanger.
Background technology
The pin-connected panel plate type heat exchanger be by the multi-disc metal through stamping out wave groove (commonly used is various stainless steels) thin plate as shown in Figure 1 at regular intervals (3mm---5mm),, form with framework and overlapping the compressing of fishbolt all around by gasket seal.
The hole, four angles of plate and gasket seal have formed the distributing pipe and the manifold trunk of fluid; The mode that whether sealing is set by hole, angle and runner intersection is reasonably separated two kinds of heat exchange mediums simultaneously, and it is flowed in the runner of every plate both sides respectively, carries out heat exchange by plate.
The pin-connected panel plate type heat exchanger have heat transfer efficiency height, volume little, can suitably increase or reduce No. of plates and satisfy technique change, install and unpick and wash characteristics such as convenient, therefore be widely used in the heat exchange between the various media in the fields such as heating, industry, food.
At present, for the sealing means between the plate, all adopt rubber sheet gasket both at home and abroad.Pad compresses through framework and fishbolt and produces strain and play sealing function.The rubber kind that is adopted has ethylene propylene diene rubber, butyronitrile rubber, fluorubber, silicon rubber, neoprene and food special (purpose) rubber etc.Because the rubber self characteristics, the use of rubber sheet gasket has restricted the scope of application of pin-connected panel plate type heat exchanger, can not normally move under some specific condition, and main deficiency has:
1, natural aging easily, hardening, elasticity reduce, and lose the effect of sealing.
2, can not be applied under the operating mode of high temperature.During the heat exchanger long-play, its operating temperature can not surpass 150 ℃, otherwise the life-span of rubber sheet gasket shortens greatly; More seriously can bring potential safety hazard.So the temperature of its operate as normal is set to below 150 ℃.When the heat exchange medium temperature surpassed 150 ℃, just needing increased Desuperheating device in addition, thereby manufacturing cost is increased, and also made volume become big; Perhaps change the heat exchanger of other type.
The heat exchange process that 3, can not adapt to special media preferably.At various industrial circles, some needs the character of the medium of heat exchange itself more to quicken aging, the inefficacy of rubber sheet gasket, needs the frequent sealing gasket of changing, and normally carrying out of influence production increased the workload of maintaining.
4, in the distributing pipe and manifold trunk of the fluid that forms in the hole, four angles of plate and pad, the sealing gasket that medium enters the porch of heat exchanger runner is spaced apart; Both on one deck plate sealing gasket was arranged, adjacent both sides plate just can not have sealing gasket, thereby causes this place's rigidity relatively poor, sealing reliability reduces, leakage takes place easily two media is mixed, cause production, quality accident, this situation is definitely unallowed in some special occasion.
Summary of the invention
The purpose of this utility model provides a kind of sealing reliability good, applied widely plate type heat exchanger with regard to being at above-mentioned the deficiencies in the prior art.
Its technical solution is as follows:
The New-type plate heat exchanger, comprise that closed assembly is the heat exchanger plate of one, adjacent two boards sheet is formed the runner that communicates at interval, the heat exchanger plate of each runner is provided with hole, two diagonal angles, wherein hole, a diagonal angle and runner conducting, then be sealing between another hole, diagonal angle and runner, the periphery of heat exchanger plate offers peripheral seal groove, corresponding each hole, angle offers annular angle hole seal groove, the peripheral seal groove of described each plate and seal the metal tape that is embedded suitable shape in the seal groove in hole, a diagonal angle with runner and twine dielectric pad, with the annular brace pad that is embedded with suitable shape respectively in the seal groove in another hole, diagonal angle of runner conducting, the periphery of above-mentioned annular brace pad has the water conservancy diversion through hole.
The utility model separates peripheral seal groove and hole, angle seal groove, just have on every plate like this five independently, the seal groove of sealing, i.e. hole, the angle seal groove of the peripheral seal groove of a similar rectangle and four annulars, the effect of each seal groove is to lay sealing gasket, supporting pad, and makes its accurate location.It also can be various stainless steels, titanium, titanium alloy, nickel, nickel alloy etc. that above-mentioned metal tape twines the employed metal of dielectric pad identical with plate material sheet.Be wound medium and be high temperature resistant, stable in properties, soft nonmetallic materials, as graphite etc.The height of metal tape (thickness of the sealing gasket of promptly making) is determined according to the distance between the plate, and is general than the big 0.2mm of the distance between the plate; The thickness of metal tape and structure can be with reference to the metal tape thickness and the structures of existing " metal twines the graphite grazing pad ".The sealing gasket of making after twining is a closed-loop; Profile should adapt with the plate seal groove.By framework and fishbolt plate and sealing gasket are evenly compressed, make sealing gasket produce strain, the nonmetal medium that extruding is twined, it is full of needs sealed space, plays the excellent sealing effect.Hole, the angle employed metal of supporting pad is identical with plate material sheet, can be various stainless steels, titanium, titanium alloy, nickel, nickel alloy etc. also, and appearance and size is consistent with hole, angle sealing gasket with thickness.Its peripheral water conservancy diversion number of openings is being exceeded under the prerequisite that weakens its intensity, mostly to be suitable as far as possible.The effect of this water conservancy diversion through hole is that distributing pipe or manifold trunk are communicated with runner, exchange media is entered or flows out runner.After by framework and fishbolt plate, hole, angle supporting pad and sealing gasket evenly being compressed, supporting pad plays and strengthens the plate effect of rigidity herein, and strut angle hole sealing gasket increases its sealing reliability greatly.
In sum, after the utility model adopts above scheme, not only have all advantages of rubber gasket plate type heat exchanger, can also adapt to the heat exchange under the multi-state more, expanded the scope of application.Owing to used metal material, it stepped a stage aspect energy savings, the environmental protection.Also solved the indeterminable a part of problem of former plate type heat exchanger of the same type, be typically following some:
(1) there is not the ageing failure phenomenon, needn't frequently changes sealing gasket, be more suitable for operating under long-term, the continual heat exchange process condition and work.
(2) encapsulant of Shi Yonging is identical with plate, can move under higher temperature, and need not increase Desuperheating device again, has reduced the production cost of heat exchanger, and the temperature of its operate as normal is brought up to more than 300 ℃ by 150 ℃.
(3) can adapt to the heat exchange process of some special media preferably, because identical with plate material sheet, the service life of sealing gasket is consistent with the service life of plate.What help producing normally carries out, and reduces the workload and the production cost of maintaining.
(4) sealing property at place, hole, angle is greatly improved, and greatly reduces the possibility that two kinds of heat exchange mediums mix mutually; Be particularly suitable in chemical industry and food service industry, using.
Below in conjunction with accompanying drawing the utility model is further described.
