Abstract
The invention relates to a manufacturing technique for a heat exchange plate of a plate reactor as well as a forming die. The manufacturing technique is characterized in that peripheral welding is conducted on two plate bodies, slow charging is conducted on the welled welded plate bodies and charging pressure is increased gradually to enable the non-clamped areas of the plate bodies to be stretched open gradually, and finally, pressure welding is conducted on the clamped points of the heat exchange plate so that the heat exchange plate with an evenly protruding surface is manufactured. The manufacturing technique and the forming die have the advantages that the manufacturing technique and the forming die are suitable for plates in various specifications, large press machines are not needed, and device and die cost for manufacturing are saved. The heat exchange plate manufactured with the manufacturing technique and the forming die can bear 5MPa external pressure at a temperate of 250 DEG C and can bear internal pressure not higher than 1MPa when the external pressure is zero, and therefore the heat exchange plate is suitable for various heat-carrying liquid-phase media such as steam, water and conduction oil.

Detailed description of the invention
Embodiment
Refer to Fig. 1, the present invention has disclosed a kind of plate-type reactor heat exchange plate manufacturing process, and its processing step is:
S1: two of plates selecting corresponding length and width according to the structure of plate-type reactor and physical dimension; Plate adopts stainless steel, mild steel or low-alloy steel material, the thickness δ=1.5 ~ 3mm of plate.
Be below the inside and outside pressure parameter that can resist corresponding to different sheet, and corresponding heat transfer coefficient:
Conclusion: along with the increase heat conductivility of sheet reduces greatly, and the ability of the interior pressure of the too low opposing of sheet and external pressure is lower.Therefore in the present invention, thickness of slab is selected this interval of 1.5～3 ㎜, can meet reactor operating pressure 1～5MPa, operating temperature-20 DEG C～250 DEG C of such condition ranges.And this scope can cover carbonylation and has been coupled the residing operating modes such as synthetic ester industry plate-type reactor, hydrogenation of oxalate for preparing ethylene glycol plate-type reactor, ester through hydrogenation alcohol plate-type reactor processed.
S2: by two plate 2 upper-lower overlappings together, the surrounding of two plates 2 is welded to the cavity that makes it to form a sealing, and reserve or offer runner hole in the end of plate 2, at runner hole place welded stub connection 1, form a unfashioned heat exchange plate.
S3: the plate that utilizes shaping dies to clamp to have welded,
The shaping dies adopting in this step, comprises patrix 4, counterdie 3, connector, clamp column and alignment pin,
Patrix 4 and counterdie 3 are uniformly distributed some clamp column 8 of stretching out patrix 4, counterdie 3 inner surfaces at non-fringe region, and each clamp column 8 is threaded with patrix 4, counterdie 3, and semicircle is arranged in the end of clamp column.
The fringe region of patrix 4 and counterdie 3 is connected and fixed by connector, adopts bolt 5 and nut 6 in the present embodiment, is only exemplary here certainly, is not circumscribed, can certainly use
The fringe region setting of patrix 4 and counterdie 3 runs through patrix 4, counterdie 3 alignment pin 7 spacing to plate 2 edges.In clamp column 8, be threaded or be welded with the stop nut that props up patrix 4, counterdie 3 inner surfaces.
The plate having welded 2 is first placed on the shaping dies being formed by patrix 4, counterdie 3, some adjustable clamp column 8 distribute on patrix 4, counterdie 3, each adjacent clamp column 8 lines form a triangle or square, diameter of phi=8 ~ the 12mm of clamp column 8, the centre-to-centre spacing A=30 ~ 80mm of adjacent clamp column 8; Clamp column 8 ends are 16mm to distance upper, mold outer surface, and its adjustable extent is ± 2mm, by regulating clamp column 8, to make its end be close to upper and lower plate outer surface; Patrix 4, counterdie 3 are bolted fixing, and utilize the relative position of the edge of alignment pin 7 to plate 2 and patrix 4, counterdie 3 to position.
Below for depressing different clamp column diameters, pressure welding point state corresponding to centre-to-centre spacing in identical:
Conclusion: the size of clamp column diameter depend on plate bulging be shaped after the required diameter of pad while carrying out Pressure Welding.Why the solder joint that these equilateral triangles (or square) distribute to be set, the pressure will make exactly plate that work can be born time in plate inner chamber.The heat transfer medium difference difference that this pressure adopts because of inner chamber, there are water, water vapour, heat conduction wet goods, the operating pressure of these media is generally between 0.2～0.8MPa, two limiting cases of this scope situation and centre-to-centre spacing A are combined, the diameter of required clamp column is 8 ㎜ and 12 ㎜, and therefore the diameter range of clamp column is decided to be Φ=8～12 ㎜.
Following table is in the present invention under identical heat-carrying agent pressure, the plate unit are flow that centre-to-centre spacing is corresponding:
Conclusion: A is less, flowing of inner chamber medium is just more difficult, and therefore, under identical pressure, A more low discharge is just less, thus heat exchange amount is also just less, and vice versa; In addition, the A more ability of platelet sheet critical external compressive resistance is just stronger, and the larger critical external compressive resistance ability of A is just more weak; Therefore A=30～80 ㎜ can critical external compressive resistance requirement, also can keep enough heat exchange amounts.
S4: the slow topping up of cavity plate 2 being formed by pipe joint 1, and the supercharging pressure that progressively raises, the non-bite region of plate 2 is progressively strutted, when strutting to the thickness T requiring, plate stops boosting, this thickness T=10 ~ 14mm;
Hydraulic pressure value and plate expanded thickness relation data record sheet
After release, open shaping dies, take out plate, form a bite area depression, but not the bubble type heat exchange plate that heave in bite region.
S5: the nip points of heat exchanging plate is carried out Pressure Welding welding, and then make the heat exchange plate that surface uniform is heaved.
After tested, the heat exchange plate that the present invention makes bears the external pressure of 5MPa at 250 DEG C, nip points welds by Pressure Welding, the inner space of each bubbling part is interconnected into the inner chamber of heat exchanger plates, inner chamber is under the stay bolt effect of solder joint, even if also can bear the interior pressure that is not more than 1MPa under the operating mode that is zero at external pressure, thereby applicable to steam, water, the multiple heat-carrying liquid phase of heat conduction wet goods media.
