Abstract
The utility model discloses a welding plate type heat exchanger, belonging to the technical field of heat exchange, and is applied to vapor-liquid and liquid-liquid heat exchange systems of industrial departments, such as petroleum, heat supply, chemical industry, power engineering, etc. Plate sheets are welded into pairs of plate sheets round a periphery. The pairs of the plate sheets are separated by seal rings to make a heat exchange working medium flow through the interiors of the pairs of the plate sheets, and to make the other working medium only pass among the pairs of the plate sheets. Flow distribution plates are arranged on the both ends of each pair of the plate sheet in a box body to make the working medium which passes among the pairs of the plate sheets distribute homogeneously. Because the utility model adopts the pairs of the welded plate sheets, the utility model is applied to a high-temperature and high-pressure heat exchange system. Secondly, each plate sheet has two holes. The two seal rings are used, and the quantity of the seal rings, and complexity and length of a shape are reduced. The incidence rate of leakage accidents is reduced effectively.
Description
The utility model belongs to technical field of heat exchange, relate to the heat exchange that is used for fluid, be the heat exchanger of a kind of plate periphery welded seal and box sealing, be applicable to vapour-liquid, the liquid-liquid heat-exchange system of each industrial department such as oil, chemical industry, heat supply, power engineering.
Heat exchanger commonly used is divided by its structure, and shell-and-tube heat exchanger (GB151-89) and plate type heat exchanger (ZB are arranged; 74001-87).Though shell-and-tube heat exchanger can bear very high pressure and temperature, because of the low equipment volume that makes of its coefficient of overall heat transmission is doted on greatly.When in the tube bank during indivedual heat-transfer pipe corrosion leakage, can't change, have to fistulae is blocked at the tube sheet place.When the heat-transfer pipe number that blocks account for the pipe sum 10% the time, this equipment is scrapped at once.Shell-and-tube heat exchanger needs tube bank is pulled out when maintenance, makes the floor space of equipment bigger.Plate type heat exchanger makes working medium when passing through the passage of being made up of plate because of the complicated ripple struction in plate surface, evokes countless turbulent flows, has destroyed the interface thermal resistance, and heat transfer efficiency is significantly improved than shell-and-tube heat exchanger.But the weakness of plate type heat exchanger maximum is that seal perimeter is long, and encapsulant is synthetic rubber, so, the chance of leakage is increased, be difficult in high temperature, high pressure is used down.Wei Kabo (VICARB) company of France has proposed the way with the whole welding of plate, makes whole heat exchanger not have seal washer, becomes non-dismountable formula, can't clean and keep in repair.
The purpose of this utility model provides a kind of dismountable peripheral welded plate type heat exchanger.The utility model is that two plates periphery around it is welded into plate is right, with high-temperature resistant seal ring with plate to separate and the steel casing of packing in, make two kinds of working medium that enter in the welded plate type heat exchanger also carry out heat exchange effectively along channel flow separately, thereby the detachable board-like heat exchanger seal perimeter of having addressed before having overcome is long, the non-dismountable problem that can't clean maintenance of full weldering plate type heat exchanger, welded plate type heat exchanger can be used under high temperature, high-pressure working condition, and have a cleaning, characteristics easy to maintenance.
Fig. 1 is a structure chart of the present utility model.Import and export for hot working fluid among the figure, 2 cold working medium are imported and exported, 3 fixed pressure plates, and 4 box sealing pads, 5 plates are right, 6 sealing rings, 7 casings, 8 flow distribution plates, 9 movable pressure plates, 10 fishbolts, 11 packing rings, 12 nuts, 15 tap holes.
Fig. 2 is the utility model plate to 5 structure chart.13 is welded perimeter among the figure, 14 holes.
Two heat exchanger plate peripheries with welding manner sealing welded perimeter 13 as shown in Figure 3. Open two holes 14 on the every plate, be used for placing sealing ring 6. Thus, consisted of plate to 5.
Hot working fluid is imported and exported 1 and with plate 5 inner chamber is communicated, and cold working medium is imported and exported 2 and communicated with casing 7, and perhaps hot working fluid import and export 1 communicate with casing 7, and cold working medium import and export 2 and plate communicate to 5 inner chamber.Specifically take which kind of mode, decide on operating mode.Separate with sealing ring 6 between the hole 14 of each plate on to 5, and realize sealing by compressing, make hot and cold two kinds of working medium through separately passage, both do not mix.
For making working medium be uniformly distributed in each plate, in casing, be provided with flow distribution plate 8 between 5.Flow distribution plate 8 is flat boards, and tap hole 15 is arranged on it.Flow distribution plate 8 is in casing 7, and plate is to 5 two ends.In the inboard of fixed pressure plate 3 and movable pressure plate 4, leave respectively and the to the greatest extent very little identical groove of casing 7 end surface shape, box sealing pad 4 is placed in the groove.When with fishbolt 10, packing ring 11, nut 12 with the tension of two pressure strips after, the two ends of casing 7 embed in the groove, make plate between 5, this realizes casing and pressure strip sealing simultaneously.
The concrete course of work of the present utility model is as follows:
The hot and cold two kinds of working medium that participate in heat exchange are entered simultaneously by import separately respectively, wherein a kind of working medium enters each plate in 5 the chamber by the upper end, another kind of working medium by the lower end enter casing through flow distribution plate enter each plate to 5 between, hot working fluid is flowed out by outlet after plate is emitted heat, and cold working medium has absorbed heat after outlet is flowed out at plate.Two kinds of working medium heat-shift between plate is to 5.
Since plate right around adopt welded seal, plate between use high-temperature seal ring, be applicable to the heat exchange of HTHP.Cold and hot working medium be at plate to carrying out, plate is to the periphery welding method, the sealing gasket peripheral length only is 1/10th to 1/15th of an equal area plate type heat exchanger length, can reduce leakage accident greatly.In addition, the utlity model has dismounting, cleaning, characteristics such as easy to maintenance.
