Technical field
The present invention relates to the heat-exchangers of the plate type that makes high temperature fluid and cryogen carry out heat exchange, particularly, thus the present invention relates to alternately form between each heat transfer plate by plug-in mounting pads such as stacked multiple heat transfer plates the peripheral parts between each heat transfer plate the stream of circulation high temperature fluid and the heat-exchangers of the plate type of stream of circulation cryogen.
Background technology
As shown in Figure 8, heat-exchangers of the plate type the tabular fixed frame 11 of the rectangle of vertical posture and vertically between the tabular movable frame 12 of the rectangle of posture with stacked multiple the OBL heat transfer plates 20 of vertical posture, 20, as shown in Figure 9, between this heat transfer plate 20 and heat transfer plate 20, alternately form the first stream 1 and the second stream 2, by the high temperature fluid H that circulates at the first stream 1, at the second stream 2 cryogen C that circulates, high temperature fluid H and cryogen C are carried out to heat exchange.
And, at four jiaos of via hole 11a～11d that are provided with as the gateway of fluid H, C of fixed frame 11, on movable frame 12, be not provided with via hole.In addition, overlapping respectively on fixed frame 11 and movable frame 12 have special plate (below, to be called " D plate ", " E plate ".）31、32。On four angles of D plate 31, be provided with via hole (unnumbered), the pad that surrounds this via hole (is called " D pad " below.) 140 be plugged between D plate 31 and fixed frame 11.In addition, on E plate 32, be not provided with via hole.
In addition, at four jiaos of via holes 21～24 that are provided with as the gateway of fluid H, C of heat transfer plate 20, be provided with heat transfer part (without numbering) at pars intermedia, at 20,20 plug-in mounting pads 130 of each heat transfer plate, make to be for example communicated with the upper and lower via hole 23,24 of the upper and lower via hole 21,22 in left side and heat transfer part and right side not to heat transfer part opening, or in contrast.
Pad 130 allosomes or the not shown stream that forms the peripheral part (along the inner side of outer peripheral edges) that surrounds each heat transfer plate 20 form the access formation pad 132 with the surrounding of pad 131 and encirclement via hole 21～24.
And, heat-exchangers of the plate type is provided with the access 3,3 that the via hole upper and lower with left side 21,22 and the first stream 1 cut off by the upper and lower access in right side is formed with pad 132, the 132 upper and lower via holes 23,24 in encirclement right side, and, by making the upper and lower via hole 21,22 in stream formation pad 131 encirclement left sides and heat transfer part be provided with the first stream 1 of circulation high temperature fluid H.
In addition, heat-exchangers of the plate type is provided with by upper and lower via holes 21,22 on the left of the upper and lower access in left side being formed surround with pad 132,132 access 3,3 that the via hole upper and lower with right side 23,24 and the second stream 2 cut off, and, form by making stream formation pad 131 surround the upper and lower access in right side the second stream 2 that is provided with circulation cryogen C with pad 132,132 and heat transfer part.
Therefore, in Fig. 9, high temperature fluid H flows through downwards in the first stream 1 and discharges from the via hole 22 of lower-left from the via hole 21 of upper left, and cryogen C upwards flows through in the second stream 2 and discharges from the via hole 23 of upper right from the via hole 24 of bottom right, thereby two fluid H, C carry out heat exchange.
In addition, though not shown, but record maqting type heat-exchangers of the plate type in patent documentation 1 grade, its with vertical posture stacked multiple by by laser weld, soldering etc. permanent engagement the boxlike plate of peripheral part etc. of two heat transfer plates, and at the peripheral part plug-in mounting pad of boxlike plate, thereby in boxlike plate, form the first stream or the second stream, between boxlike plate and boxlike plate, form the second stream or the first stream.
In addition, in patent documentation 2, record heat-exchangers of the plate type, its plug-in mounting stream between heat transfer plate forms with pad and the access formation integrated pad forming of pad, has the formation of plug-in mounting stream a part and the access of pad arranged side by side form bilayer (two) pad forming by a part for pad at the boundary member of heat transfer part and via hole.This heat-exchangers of the plate type is characterised in that, double-deck pad does not use bonding agent to be fixed to heat transfer plate, and the pad of other parts uses bonding agent to bond to heat transfer plate.
And double-deck pad is inserted between stacked heat transfer plate every one (replacing), thus be formed with without double-deck pad be communicated with the stream of heat transfer part and via hole.The heat transfer plate of the part of this bilayer pad of plug-in mounting is not easily because interior pressure is out of shape, but because double-deck pad does not bond to heat transfer plate by bonding agent, therefore the resistance to pressure of heat-exchangers of the plate type is improved.

Patent documentation 2: Japanese patent laid-open 9-72686 communique
But, in the existing heat-exchangers of the plate type shown in above-mentioned Fig. 8 and Fig. 9, there is following problem.
As shown in Figure 9, in heat-exchangers of the plate type, the high temperature fluid H that flows into the first stream 1 is forming by the access that surrounds via hole 21 the interior circulation of access 3 forming with pad 132.As shown in figure 10, access at the access 3 that forms this high temperature fluid H circulation forms with in pad 132, the inner side (liquid contact side) contacting with high temperature fluid H under hygrothermal environment, thereby because long use can cause solidifying or softeningly wait hot deteriorated deterioration.
In addition, this access formation is macromolecule (RH) by the principal component of pad 132, so heated and react with oxygen (O2) by high temperature fluid H, generates alkyl (R-).And stream forms uses the outside (on-liquid contact side) of pad 131 to contact with atmosphere, alkyl (R-) generates peroxy radical (ROO-) with oxygen reaction.This peroxy radical (ROO-) reacts with macromolecule (RH) and generates peroxide (ROOH).(ROOH) is unstable for this peroxide, is easily decomposed into alkoxyl (RO-) and hydroxyl (OH-).
In a word, the access that forms the access 3 of high temperature fluid H circulation forms uses the liquid contact side of pad 132 to contact with high temperature fluid H, and on-liquid contact side contacts with atmosphere.Therefore, as the macromolecule of principal component, because of oxidative degradation reaction avalanche, group number increases, and impels cut-out, the cross-linking reaction of strand.And, thus, lose the original elasticity of rubber, and structurally, because access forms with pad 132 under compression environment, therefore the fracture that the development of the contact deficiency that the development of generation compression set causes, crackle causes.And this fracture often makes high temperature fluid H leak in the second stream and mix with cryogen C from access 3.
In addition, in the heat-exchangers of the plate type of recording at patent documentation 2, be fitted with double-deck pad in inside.But the access formation pad 132 that forms the access 3 of high temperature fluid H circulation is not set as bilayer, thereby oxidative degradation occurs, high temperature fluid H can leak to outside sometimes.
And, be dangerous liquid at high temperature fluid H, once the high temperature fluid H leaking from heat-exchangers of the plate type flows out to outside, there is sometimes secondary disaster.If not there is not secondary disaster and change ahead of time pad, operating cost rises.In addition, also considered the whole heat-exchangers of the plate type of the coverings such as the sheet material high by air-tightness or inserted rubber etc. to the gap of the periphery edge between stacked heat transfer plate and suppress oxidative degradation and avoid high temperature fluid H to flow out to outside method, but such method is adopted because of cost aspect or quality aspect existing problems.

Detailed description of the invention
Referring to figs. 1 through Fig. 3, the first embodiment of heat-exchangers of the plate type involved in the present invention is described.But, part same as the prior art is marked to identical symbol and describes.In addition, waiting up and down of narrating in the following description is an example of each embodiment, in actual occupation mode, is different positions sometimes certainly.
As shown in Figure 1 to Figure 3, the heat-exchangers of the plate type of the first embodiment is same with prior art, between heat transfer plate 20 and heat transfer plate 20, alternately to form the first stream 1 and the second stream 2, circulate high temperature fluid H and at the circulate device of cryogen C of the second stream 2, utilize the pad 30 being inserted between heat transfer plate 20 and heat transfer plate 20 that the first stream 1 and the second stream 2 are set at the first stream 1.
Pad 30 stream that (shown in Fig. 1 and Fig. 2) or allosome ground (shown in Fig. 3) is formed with the peripheral part that surrounds heat transfer plate 20 integratedly forms and forms with pad 32 with pad 31 and the access that surrounds the surrounding of via hole 21～24.As shown in Figure 2, form stream formation pad 31 and access and form with in the pad 30 of pad 32, the boundary member of heat transfer part and via hole 21～24 is shared.
And, in the heat-exchangers of the plate type of the first embodiment, as shown in Figure 2, the access that the access 3 of high temperature fluid H circulation is set forms and is formed as inboard washer parts 32a and outside gasket part 32b bilayer with pad (following, to be called " dual pad ") 32.Therefore,, on heat transfer plate 20, be formed with accordingly double-deck groove with inboard washer parts 32a and the outside gasket part 32b of dual pad 32.
In addition, inboard washer parts 32a is formed as circular in the mode of surrounding via hole 21,22.And outside gasket part 32b is formed as being out of shape trapezoidal shape, form boundary member shared with pad 31 and the second stream 2 with stream.
In addition, as shown in Figure 3, the formation of allosome formation stream is formed with the circular inboard washer parts 32a that surrounds via hole 21,22 and the circular outside gasket part 32b bilayer that surrounds these inboard washer parts 32a with the dual pad 32 of pad 31 and access formation pad 32 side by side in concentric mode.Therefore, gasket part 32b in outside does not form the part shared with pad 31 with stream.
And, surround the upper and lower via hole 21,22 in left side by dual pad 32, thereby be provided with the access 3 mobile for high temperature fluid H.In addition, although (below, be called " substance pad " by the general pad using in prior art.) 130 access forms and surround the upper and lower via hole in right side 23,24 with pad 132 and be provided for the mobile access of cryogen C 3, still also can surround the upper and lower via hole in right side 23,24 by dual pad 32 is provided for the mobile access of cryogen C 3.
And, the access formation of substance pad 130 cuts off the upper and lower via hole in right side 23,24 with pad 132, stream formation is inserted between two heat transfer plates 20,20 to surround the upper and lower via hole 21,22 in left side and the mode of heat transfer part with pad 131, thereby is provided for the first stream 1 of high temperature fluid H circulation.
In addition,, although do not illustrate, also can be formed with side by side inboard washer parts and outside gasket part bilayer for the stream formation pad 131 that the first stream 1 is set.Thus, can be used in the pad that the first stream 1 is set and can not produce oxidative degradation.And, also can be formed with side by side inboard washer parts and outside gasket part bilayer for the stream formation pad 131 that the second stream 2 is set.Thus, can assemble without distinguishing the first stream 1 and the second stream 2.
And, pad 30, substance pad 130 are alternately inserted between adjacent heat transfer plate 20,20, thus, high temperature fluid H flows through in the first stream 1 and discharges from the via hole 22 of bottom, left side from the via hole 21 of left upper portion, on the other hand, cryogen C flows through in the second stream 2 and discharges from the via hole 23 of right upper portion from the via hole 24 of lower right side, thereby high temperature fluid H and cryogen C carry out heat exchange.
Now, high temperature fluid H is in the interior circulation of access 3 of left upper portion and flow in the first stream 1.High temperature fluid H in this access 3 contacts with the inboard washer parts 32a of dual pad 32, still, because the surrounding of these inboard washer parts 32a is surrounded by outside gasket part 32b, therefore, can not contact with atmosphere, is difficult to occur oxidative degradation reaction.
In addition, lower the temperature with cryogen C heat exchange at the high temperature fluid H of the access 3 interior circulations of bottom, left side, therefore, the pad 32 that is used to form the access 3 of bottom, left side can not be also bilayer but individual layer.In addition, even if for the access 3 that the upper and lower via hole in right side 23,24 is communicated with is arranged by the access formation pad 132 of substance pad 130, also be at the interior circulation cryogen of this access 3 C, access forms the high temperature that can not become generation oxidative degradation degree with pad 132.
Therefore, this heat-exchangers of the plate type is that dual pad 32 can not crack and high temperature fluid H can be from the heat exchanger of access 3 internal leakages.
Below, with reference to Fig. 2 to Fig. 6, the second embodiment of heat-exchangers of the plate type involved in the present invention is described.In the second embodiment, it is characterized in that, on the heat transfer plate 20 of the part clipping at inboard washer parts 32a and the outside gasket part 32b of dual pad 32, be provided with outage 25 and to both or one only in pore 26.
In order to discharge the high temperature fluid H leaking from the inboard washer parts 32a of dual pad 32, the pad 33 of plug-in mounting ring-type between the heat transfer plate 20,20 for the first stream 1 is set, thus can make outage 25 continuously by this pad 33.
And as shown in Figure 4, the nozzle 13 continuous with outage 25 is installed in fixed frame 11, as shown in Figure 6, if high temperature fluid H leaks from this nozzle 13, can detect as inboard washer parts 32a is because leakage has occurred crackle etc.
In addition, Fig. 5 and Fig. 6 also show the state that the dual pad 32 shown in Fig. 2 is plugged between heat transfer plate 20, is inserted into double-deck D pad 41, the 42 encirclement intercommunicating pores 21 between fixed frame 11 and D plate 20d, but, even if the dual pad 32 shown in heat-exchangers of the plate type Fig. 3 of the second embodiment also can be implemented.
No matter which kind of situation, forms to pore 26 for inboard washer parts 32a is difficult for oxidative degradation reaction further occurs., in the confined space of surrounding to pore 26 to the inboard washer parts 32a by dual pad 32 and outside gasket part 32b and two heat transfer plates 20, supply with the inert gases such as nitrogen, inboard washer parts 32a is not contacted completely with oxygen.
And, because this confined space is adjacent with the first stream 1 across heat transfer plate 20, therefore, by the pad 33 of the ring-type continuous with giving pore 26 of plug-in mounting between the heat transfer plate 20,20 for the first stream 1 is set, thereby this confined space is communicated with this pad 33, supplies with inert gas from the nozzle 14 that is installed on frame 11 in confined space.As shown in Figure 4, be installed on fixed frame 11 for the nozzle 14 of supplying with this inert gas.
In addition, can be only the access 3 of left upper portion to the circulation of high temperature fluid H high temperature outage 25 is set and to pore 26, but, also can outage 25 be set and to pore 26 to the dual pad 32 of the access 3 of the bottom, left side for high temperature fluid H after cooling circulation is set, thereby can assemble with spinning upside down.Therefore, the outage 25 in this situation and give that pore 26 is formed on while turning upside down, outage 25 is on the position that is outage 25 to pore 26, to pore 26.
Below, with reference to Fig. 7, the 3rd embodiment of heat-exchangers of the plate type involved in the present invention is described.The 3rd embodiment is characterized in that, be laminated with vertical posture multiple boxlike plate 200 and boxlike plate 200 between the dual pad 32 of plug-in mounting.
Boxlike plate 200 is to form by the peripheral part of two heat transfer plates 20,20 forever being connected to (representing with stain in Fig. 7) with laser weld or soldering etc., is provided with the first stream 1 of circulation high temperature fluid H or the second stream 2 of circulation cryogen C in inside.
And stacked multiple boxlike plates 200 are provided with the second stream 2 of circulation cryogen C or the first stream 1 of circulation high temperature fluid H between boxlike plate 200 and boxlike plate 200.The dual pad 30 of peripheral part plug-in mounting at this stacked boxlike plate 200 with boxlike plate 200.
The stream formation that pad 30 combinations are plugged in the peripheral part of the permanent connection of boxlike plate 200 forms with pad (not shown) with for the dual pad 32 that access 3 is set.Dual pad 32 is provided with the circular inboard washer parts 32a that surrounds via hole 21,22 and the outside gasket part 32b that surrounds these inboard washer parts 32a side by side in concentric mode.Outside gasket part 31b is plugged in the inner side of permanent connection in illustrated mode.
Or, although diagram not,, outside gasket part 32b is plugged between the part of permanent connection 201, and inboard washer parts 31a is plugged in the inner side (in Fig. 7 for being plugged in the outline line (line) of outside gasket part 31b) of permanent connection.
In order to make the first stream 1 interior circulation of high temperature fluid H in boxlike plate 200, high temperature fluid H is also in the interior circulation of access 3.Access 3 forms by the dual pad 32 that surrounds via hole 21,22.Although the inboard washer parts 32a of dual pad 32 contacts with high temperature fluid H,, suppressed with the reacting of oxygen in atmosphere, oxidative degradation is suppressed.
