Abstract
The invention discloses a plate type falling-film heat exchanger with high heat exchange efficiency. The plate type falling-film heat exchanger comprises a shell, wherein a film distributor is arranged on the top in the shell; a heat exchange plate is vertically arranged below the film distributor; a medium outlet is formed at the upper end of the heat exchange plate, and a medium inlet is formed at the lower end of the heat exchange plate; the heat exchange plate is formed by welding the peripheries of two flat plates; expanding bags are densely arranged between the two flat plates; and a roundabout medium passage for connecting the medium inlet and the medium outlet is formed between the two flat plates. The plate type falling-film heat exchanger has the advantages that: the expanding bags are arranged on the plate type heat exchange plate, so that the heat transfer area of media inside and outside the heat exchange plate is increased; and the roundabout medium passage prolongs the stay time of the medium in the heat exchange plate, so that the heat exchange is performed more sufficiently, and the efficiency is higher.
Description
Technical field
The present invention relates to a kind of board-like falling liquid film heat exchanger.
Background technology
Be applied to liquid-liquid heat exchange occasion; For obtaining best heat-transfer effect, generally adopt full counter-flow designs, this heat exchanger is used at present the most extensively has shell-and-tube heat exchanger, plate type heat exchanger, spiral-plate heat exchanger etc.; Wherein the heat transfer coefficient of shell-and-tube heat exchanger is minimum, and structure is not compact; The plate type heat exchanger heat transfer coefficient is high, but adopts the sealing gasket sealing, causes leakage easily, and in addition, passage has only 2-5mm between plate, easy blocking passage when heat transferring medium contains solid or fiber; The spiral-plate heat exchanger heat transfer coefficient is high, but the maintenance difficulty is broken as the inner ring spiral plate takes place, just can make whole equipment scrapping.
Summary of the invention
Technical problem to be solved by this invention is: high, the difficult leakage of a kind of heat exchange efficiency is provided, is difficult for obstruction, the board-like easily falling liquid film heat exchanger of maintenance.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: a kind of board-like falling liquid film heat exchanger comprises housing; The enclosure interior top is provided with filming device, and the below of filming device is vertically installed with heat exchange plate, and the upper end of heat exchange plate is provided with media outlet; The lower end is provided with the medium import; Said heat exchange plate is welded by around two flat boards, is densely covered with the bag that expands between two flat boards, is provided with the circuitous medium channel that connects medium import and media outlet between two flat boards.
During work, medium A flows with membranaceous in the heat exchange plate outside from top to bottom, and medium B flows at the heat exchange plate inner chamber from bottom to top, is full adverse current between medium A and the medium B like this.
The weld seams of many parallel and dislocation are set between said two flat boards from top to bottom, weld seam start from two dull and stereotyped same one side and and opposite side between leave certain distance.
The invention has the beneficial effects as follows: the bag that expands is set on the plate-type heat-exchange plate; Increased the heat transfer area of the inside and outside medium of heat exchange plate; And improved the flow velocity of medium in
heat exchange plate after circuitous medium channel is set, thereby improved its heat transfer coefficient.

Among the figure: 1, housing, 2, filming device, 3, heat exchange plate, 4, media outlet, 5, the medium import, 6, flat board, 7, the bag that expands, 8, medium channel, 9, weld seam.
The specific embodiment
Below in conjunction with accompanying drawing, describe specific embodiments of the present invention in detail.
As shown in Figure 1, board-like falling liquid film heat exchanger of the present invention comprises housing 1, and housing 1 inner tip is provided with filming device 2, and the below of filming device 2 is vertically installed with heat exchange plate 3.Like Fig. 2, shown in Figure 3; Said heat exchange plate 3 is by being welded around two flat boards 6; And the upper end of heat exchange plate 3 is provided with media outlet 4; The lower end is provided with and is densely covered with bag 7, two dull and stereotyped 6 the circuitous medium channels 8 that are provided with import 5 of connection medium and media outlet 4 that expand between the medium import 5, two dull and stereotyped 6.Between two dull and stereotyped 6, contact point is set, and the position of these contacts is welded, then two dull and stereotyped 6 remainders are heaved, will form the bag 7 that expands according to certain layout.During actual production; Many parallel and misplace weld seams 9 are set between said two dull and stereotyped 6 from top to bottom; Promptly weld together two dull and stereotyped 6 along arranging of weld seam 9; Weld seam 9 start from same one side of two dull and stereotyped 6 and and opposite side between leave certain distance, form a medium channel 8 that makes a circulation that is connected medium import 5 and media outlet 4 between 9 of adjacent like this weld seams and weld seam 9 and dull and stereotyped 6 edges.
The course of work of the present invention is: as shown in Figure 1; Medium A is through the outer surface of filming device 2 cloth films at heat exchange plate 3; And medium B gets in the heat exchange plates 3 from the lower end medium import of heat exchange plate 35, gets in the heat exchange plate 3 back and upwards flows along medium channel 8 is circuitous, flows out until the media outlet 4 from the upper end; Medium B in the heat exchange plate 3 carries out heat exchange through flat board 6 and the medium A on heat exchange plate 3 outer surfaces in flow process.Medium A and medium B are full countercurrent direction and flow, so in the arbitrfary point of plate, have rational heat transfer temperature difference between medium A and the medium B; Equally distributed expansion bag 7 on the plate-type heat-exchange plate 3; The runner of medium B is provided on the one hand, has also constantly changed the flow velocity and the flow direction of medium B on the other hand, thereby strengthened the heat transfer of medium B; The heat transfer coefficient of then further having strengthened medium B behind the circuitous medium channel 8 is set, and efficient is higher.
