Abstract

The utility model relates to a dismountable plate shell type exchanger. Every two corrugated plates are welded into a set, a flow channel is formed, two sets of plates are assembled, the other flow channel is formed between the two sets of the plates, and a complete machine is composed of a plurality of sets of the plates. Each sets of the plates is are welded with two connecting pipes (7) and (14), the connecting pipe (7) which is provided with a loose joint is welded with a connecting pipe (6), the connecting pipe (14) is connected with a pipe sheet (12) by a nut (15), so the utility model can bear the high temperature of 450 DGE. C and the pressure of 8.0 million pascals. The utility model has the advantages that the structure is simple, the utility model is dismountable, the fabrication is convenient, the effect of sealing is favorable, the utility model can resistance high temperatures, the utility model can resistance pressure, the utility model can resistance the corrosions, etc.

Description

The demountable panel shell heat exchanger

The utility model discloses a kind of heat-exchanger rig, specifically a kind of demountable panel shell heat exchanger.

Existing plate type heat exchanger is owing to adopted the rubber cushion sealing to make the plate type heat exchanger working pressure can only be limited to below the 2.0MP more at large, temperature is limited to below 200 °, the medium that some corrosivity is stronger can not use, welded plate heat exchanger does not have dismoutability again, and pipe heat exchanger exists heat transfer efficiency low, is not easy to shortcomings such as disassembly, cleaning.

The purpose of this utility model is to provide a kind of high temperature resistant, high pressure resistant, corrosion-resistant, heat transfer efficiency height, demountable panel shell heat exchanger rational in infrastructure.

The purpose of this utility model is to realize like this.This heat exchanger is that per two corrugated plating plates are welded into one group, form a runner, again two groups of plate assemblings, make and form another runner between two groups of plates, many group plates are formed a complete machine, and every group of plate welds a pipe adapter, and an adapter is joined with the suction flange pipe with the connecting leg welding again, make this runner can bear 450 ℃ of high temperature, pressure 8.0MP., because without rubber cushion sealing, can realize corrosion-resistantly, another runner can be realized 400 ℃ of high temperature, pressure 10MP by housing., corrosion-resistant and detachable.

The utility model has been cancelled the rubber cushion structure owing to changed the hermetically-sealed construction of plate type heat exchanger, and it is simple in structure that this invention is had, and is detachable, easily manufactured, good sealing effect, and heatproof, withstand voltage, corrosion-resistant, advantages such as low cost of manufacture.

This kind heat exchanger is compared use with the ZL993203523.X plate type heat exchanger material scope is wide, realized that promptly carbon steel, copper, the multiple metal material of aluminium all can use, flow realizes not waiting flow between plate, corrugated plating can realize that multiple structure assembling is to adapt to different field, enlarged range of application, its heat transfer efficiency improves 20%, and fluid resistance has reduced by 40%, and heat exchange when having realized multiple medium.

Accompanying drawings embodiment:

Fig. 1 is removable lamella heat exchanger overall structure schematic diagram.

Fig. 2 is an A-A face partial cutaway diagrammatic sketch.

Describe the working condition of concrete structure of the present utility model and medium in detail below in conjunction with accompanying drawing.

From Fig. 1, learn in 2: this heat exchanger is by suction flange in the plate (1), sealing flange (2), seal receptacle (3), end socket (4), connecting leg flange (5), connecting leg (6), (7), corrugated plating (8) are taken in loose joint, cylindrical shell (9), suction flange between plate (10), bolt, nut (11) (15), tube sheet (12), cover flange (13), take over (14), bearing critical pieces such as (16) is formed, and enters in the suction flange 1 in the medium I slave plate, by sealing flange 2, seal receptacle 3, end socket 4, connecting leg flange 5 and connecting leg 6 enter loose joint and take over 7. corrugated plating groups 8, from taking over 14, tube sheet 12, nut 15 comes out to form a runner by the B mouth; Suction flange 10 enters corrugated plating group 8 (sealing by cylindrical shell 9 between the corrugated plating group) between medium II slave plate, comes out to form another kind of medium runner from the A mouth, and medium I, II flow in two kinds of runners respectively, form the heat exchange of two media.
