Description
Technical field
The method that the present invention relates to carry out between heat-exchangers of the plate type hot setting seal gasket and plate separating, specifically it is scratched when rubber cushion or the most aging when being unable to reach sealing effectiveness and need to change, realizing the clean reliable separation between hot setting seal gasket and plate on the premise of not damaging plate, the cleaning and the seal gasket that are beneficial to plate are bonding with the hot setting again of plate.
Background technology
Heat-exchangers of the plate type is that a kind of heat transfer efficiency is high, easy to assemble, the heat-exchange apparatus of easy cleaning.Rely between its every plate and plate seal gasket realize heat transfer medium certain pressure and at a temperature of sealing and form cold and hot passage, it is ensured that cold and hot medium is in the both sides of every plate inversely or co-flow realizes heat exchange.In order to make seal gasket effectively location and not vibration in plate spacer groove, really realize effective sealing effectiveness, bonding agent is generally used to be bonded in by seal gasket in plate spacer groove, it is to avoid the rubber cushion vibration or position inaccurate and affect sealing effectiveness when plate assembles.In order to make rubber cushion bonding firmly, during preventing from unpicking and washing, rubber cushion comes off, deform and more renew pad, extend the service life of rubber cushion, best bet is to use solidification glue that seal gasket carries out (high temperature) with plate to solidify bonding at present, make plate can not separate obscission with rubber cushion when assembling and disassembly, cleaning, rubber cushion do not produce surface serious damage or aging in the case of, its life-span can once be extended to 5 to eight years (different temperatures by the most cleaned and changed, in ageing term under environment), greatly increase the service life of seal gasket, significantly reduce the operating cost of heat-exchangers of the plate type.
But there is a fatal problem in hot setting seal gasket, that scratch when seal gasket exactly or the most aging cannot realize sealing effectiveness and when need to change, it is difficult to be separated on plate by seal gasket, remove and ensure in the case of not damaging plate the cleaning of spacer groove, takes artificial or certain machinery to carry out clearing up and be all unable to reach preferable technique effect in the past.Cause this problem to become this field to thirst for for a long time solving the most insurmountable technical barrier.
Summary of the invention
It is an object of the invention to provide the hot setting seal gasket of a kind of heat-exchangers of the plate type and the separation method of plate, the seal gasket of hot setting totally can be completely separated in the case of not damaging plate on plate by described method, make this field for a long time thirst for solve and the most unsolved technical barrier is solved.
The hot setting seal gasket of heat-exchangers of the plate type of the present invention and the separation method of plate, separated by high-temperature heating or liquid nitrogen refrigerated separation technique forms, it is that high temperature heat source is directly directed at the plate side bottom gasket seal that wherein said high-temperature heating separates, high-temperature heating is proceeded by the telltale hole that gasket seal is the most bonding with plate, simultaneously with special fixture pinch seal pad, limit heating edge is by seal gasket pull-up and departs from plate；Described liquid nitrogen refrigerated separation is the plate that multiple are to be separated to be put into cuboid seal container, in sealing container, it is filled with liquid nitrogen gas plate to be separated is carried out sub-cooled, within 4 to 5 seconds, stopping inflation, in container to be sealed, temperature reaches or takes out during close to room temperature.
During described high-temperature heating, plate local temperature is 300 to 450 DEG C.
During described sub-cooled, in sealing container, temperature is-30 to-45 DEG C.
The high-temperature heating of the present invention and liquid nitrogen refrigerated separation method, it is the difference utilizing plate material sheet, seal gasket and solidification its heat conductivity of glue material to exist, in the case of being quickly heated or cooled, seal gasket, solidification glue are different from the rate of heat transfer of plate, and both are separated by the difference of the line swollen contracting amount that moment produces.It is the scientific and effective method exploring out in production practices, can be on the premise of not changing plate material sheet combination property, realize the hot setting seal gasket of heat-exchangers of the plate type and the reliable separation of plate, and speed is fast, effective, and to have that inventive concept novelty is unique, operation is easy to implement easy, significantly improves work efficiency.Suitably carry out the advantages such as popularization energetically.Compared with prior art there is prominent substantive distinguishing features with the most progressive.
Detailed description of the invention
The hot setting seal gasket of heat-exchangers of the plate type of the present invention and the separation method of plate are based on the difference that plate material sheet, seal gasket and solidification its heat conductivity of glue material exist, and (plate material sheet is rustless steel, titanium, nickel and nickel-base alloy etc. under normal circumstances, its heat conductivity is in the range of 15～30W/m K, and gasket seal material is generally NBR, ethylene-propylene diene copolymer, silica gel etc., its heat conductivity is in the range of 0.15～0.27W/m K, and the heat conductivity of the resin glue not containing metal that solidification uses is at 0.25W/m about K.I.e. plate material sheet differs more than 80 times with the heat conductivity of gasket seal and solidification glue), and a kind of scientific and effective method taked.It is made up of high-temperature heating separation 1 or liquid nitrogen refrigerated separation 2 technique, it is that the high temperature heat source being set up a separatist regime by force of arms flame by oxygen+acetylene or high-frequency inductor is formed directly is directed at the plate side i.e. back side of spacer groove bottom seal gasket that wherein said high-temperature heating separates 1, should proceed by from the telltale hole that seal gasket is the most bonding with plate when flame is high temperature heat source when being set up a separatist regime by force of arms by oxygen+acetylene, when high-temperature heating, the local temperature of plate (stainless steel material) is 340 to 350 DEG C and achieves that seal gasket comes off.Special fixture pinch seal pad to be used, heats and makes it completely disengage from plate seal gasket pull-up from plate.In actual mechanical process, high temperature heat source and plate spacing should not be too near or heat time heating time is long, and it suitably can regulate according to the thickness of the size of flame and plate, it is easy to grasps.
Described liquid nitrogen refrigerated separation 2 is that the cuboid put into by the plate that multiple are to be separated and be provided with heat-insulation layer seals container, buckle closure seals, sealed container outside is provided with air-filled pore, non-return valve, temperature gauge stand and thermometer, in sealing container, it is filled with liquid nitrogen gas through air-filled pore and plate to be separated is carried out sub-cooled, during 5 seconds sealing container Nei Wenduda-35 to-40 DEG C, stopping inflation, in container to be sealed, temperature reaches or takes out during close to room temperature.
