Description
Technical field: the utility model relates to a kind of heat transmission equipment, particularly relates to a kind of welded plate type heat transmission equipment.
Background technology: plate type heat exchanger has that efficient heat transfer, floor space are little, working service characteristics easily, thereby is widely used in numerous areas such as heat supply, metallurgy, oil, chemical industry, papermaking.The critical component of plate type heat exchanger is exactly a plate, and the plate great majority of plate type heat exchanger are corrugated plating, because the restriction on the corrugated board structures is only applicable to the conventional media heat exchange.As water-water heat exchange, vapour-water heat exchange, oil-technical process such as water heat exchange.But for some special fields, cooling as the saccharification in black liquid, the ethanol preparation, liquefaction and fermentation procedure mash, intermediate temperature drop link of system Aluminum decomposing grading operation in aluminum oxide production process or the like, in described these fields, the medium that need carry out heat exchange generally all contains a large amount of solid particles, fibre suspension or for thick.So just must use the heat exchanger of anti-obstruction, anti-erosion performance to satisfy the demand of special process process heat transferring medium.In order to address this problem, the fat pipe heat exchanger that the plate formation of taking cellular structure is arranged at present, so-called cellular structure be exactly at plate horizontal stroke, vertically equidistantly distribute raised or sunken (this raised or sunken positive and negative of a plate that is meant is promptly for A, the B plate) of progressive circle, A, the two protruding summit butt welding of B plate are the welding fulcrum and form passage that many plates welding constitute the plate bundles.And its plate is circular-arc along the edge length direction, and the circular-arc edge that imports and exports in corresponding heat exchanger channel is provided with breach.Though the heat exchanger that is made of this plate can be used for the heat exchange of the above special media, but its heat transfer coefficient is not high, cause heat exchange efficiency undesirable, and because the passage import and export are jagged, for the medium that prevents adjacent two passages mixes in indentation, there, just must weld a separator again with two channel separation in indentation, there.Because the existence of separator not only makes trouble, and also will cause the flow dead of circular arc passage, adds the particularity of medium, long-term work will certainly blocking channel.Heat exchange efficiency is greatly reduced.
Summary of the invention: the purpose of this utility model mainly is that the plate heat transfer coefficient that solves in the existing welded plate type heat exchanger is not high, cause heat exchange efficiency undesirable, the existence of importing and exporting breach with passage makes troubles to manufacturing, thereby and cause the flow dead blocking channel of circular arc passage, the problem that heat exchange efficiency is reduced.
Scheme of the present utility model is as described below: this utility model comprises base, the plate bundle of forming by welded plate on the base, plate bundle both sides clamping plate, fishbolt, import and export wide that passage is provided with at the plate bundle, the narrow passage collecting box, the collecting box cover plate, flange, and sealing ring, hinge, connecting bolt, nut, exhaust outlet, it is to be circular arc by in the quadrangle of being made up of arbitrarily the welding fulcrum two ends are set on the plate of existing cellular structure, the centre is rectilinear flow-disturbing section, and is provided with along the set inboard, circular-arc edge of length in plate one side that the passage of projection and the alternate formation of depression import and export to constitute.
Described flow-disturbing section is progressive raised or sunken (referring to A, B plate), its raised or sunken direction is identical or opposite with the welding fulcrum, the summit is lower than the welding fulcrum when identical, this flow-disturbing section laterally or vertically is arranged alternately with the welding fulcrum, leans on number row or row in itself with even number line or be listed as symmetrical.
The utility model compared with prior art has the following advantages and beneficial effect:
1, owing to be provided with the flow-disturbing section, increased flow-disturbing effect and heat transfer coefficient, guaranteed to have improved the heat exchange efficiency of heat exchanger effectively under the less situation of drag losses.
2, owing to be provided with projection and import and export, not only reduced the trouble of making, and overcome the flow dead of circular arc passage, avoided the obstruction of medium channel, simultaneously more convenient cleaning with the passage of the alternate formation of depression.
3, the novel uniqueness of plate, structural design compact and reasonable, stable and reliable working performance, suitable multiple industry use, product have a extensive future, are convenient to widely popularize in the industry.

The specific embodiment: the fat pipe welded plate type heat exchanger is improved a kind of novel welded plate type heat exchanger on the prior art basis.Core component of the present utility model is a plate 1, this plate 1 is on the plate of existing cellular structure, two ends are set are circular arc in the quadrangles of forming arbitrarily by welding fulcrum 2, middlely be rectilinear flow-disturbing section 3, and in plate 1 one sides projection and the passage of the alternate formation of depression are set along the inboard at the set circular-arc edge of length and import and export 4 formations.Flow-disturbing section 3 on the plate 1 is progressive raised or sunken (referring to A, B plate difference), its raised or sunken direction can be identical or opposite with welding fulcrum 2, the summit is lower than welding fulcrum (purpose is in order to reduce resistance) 2 when identical, flow-disturbing section 3 on the plate 1 can be laterally or vertically with weld fulcrum 2 and be arranged alternately, with regard to flow-disturbing section 3 itself, leaning on number row or row and even number line or row is symmetrically set.It is better that this setting can make flow-disturbing section 3 corresponding on A, the B plate become intersection symmetric mode (as Fig. 4, shown in Figure 6) heat-transfer effect.With A, that the B plate is welded to form plate earlier is right, again by plate to being welded into plate bundle 5, respectively there is a clamping plate 6 plate bundle 5 both sides, and are with fishbolt 7, nut 8 that plate bundle 5 is fixing with clamping plate 6.Plate bundle 5 bottoms are base 9, the top and the bottom of plate bundle 5 on or the narrow passage that forms of bottom import and export 4 places and be provided with narrow passage collecting box 10 and flange plate 11.This collecting box 10 can be made into removable and fixed two kinds.Be respectively equipped with fat pipe collecting box 12 and fat pipe flange plate 13 in addition at the two ends of plate bundle 5, fat pipe collecting box 12 is fixing with fat pipe flange plate 13 by hinge 14, and establishes sealing ring in the junction.Top at fat pipe collecting box 12 also is provided with exhaust outlet 15.
During work, heat transferring medium is respectively by the extremely outlet of import, heat exchanger channels, with the heat transferred cryogen, cryogen is heated high temperature fluid by plate 1, and high temperature fluid is cooled, in whole heat transfer process, owing to be provided with flow-disturbing section 3 on the plate 1, increased flow-disturbing effect and heat transfer coefficient, and do not had flow dead in the passage, in case medium stops up, improved the heat exchange efficiency of heat exchanger effectively.
