Description

A kind of five-part form plate type heat exchanger

Technical field

The utility model relates to a kind of heat exchanger, specifically refers to a kind of multisection type plate type heat exchanger.

Background technology

Plate type heat exchanger (PHE) has the advantages such as heat transfer efficiency is high, compact conformation, floor space are little and cheap, again due to fluid flow between heat exchanger plate can be and flow, adverse current or cross-flow, plate can also increase and decrease according to the size of heat transfer area, and therefore adaptability is stronger.Be widely used in petrochemical industry, light industry and food, the fields such as metallurgical environmental protection, concentrated supply of heating in the city, ship power and offshore engineering.

Multistage plate type heat exchanger a multitude of names of current similar application, but structure is simple on the whole, and combination hop count is few, and working media is few, and every section of single process, and can not adapt to the demand of complex working condition, treating capacity is lower, and the scope of application is limited; Folding journey plate used is exactly common corrugated cardboard sheet, usual thickness δ=0.6mm, or thinner, if Long-Time Service, be subject to the pulsatile impact of fluid, due to the corrosiveness of medium, plate is easy to fatigue rupture occurs, and causes plate internal leak, increases maintenance cost.

Utility model content

The utility model provides a kind of five-part form plate type heat exchanger, substantially increases treating capacity and the utilization rate of equipment, decreases cost of investment, saved the energy, prevents the destruction of folding journey plate, decreases maintenance cost.

For achieving the above object, the utility model is by the following technical solutions:

A kind of five-part form plate type heat exchanger, comprises corrugated cardboard sheet, its by fixing, movable plate body, upper and lower beam and front support rod form framework, installs first, second, third, fourth central dividing plate in this framework; Clamp with the fishbolt be arranged on fixing, movable plate body after the corrugated cardboard sheet mutually sealed all is installed between fixed plate body with the 4th central dividing plate, between first, second, third, fourth central dividing plate, between the first central dividing plate with movable plate body and make it into as a whole and form described five-part form plate type heat exchanger.

Folding journey plate is set between described 3rd, the 4th central dividing plate.

Described folding journey plate thickness is 5mm.

The utility model can make full use of the waste heat of steam waste heat and condensed water to opposite side laser heating in engineer applied, can make full use of industrial exhaust heat, energy-saving and emission-reduction, and equipment separate unit treating capacity enlarges markedly.

Fig. 3 is the utility model folding journey plate structure schematic diagram.

Detailed description of the invention

Below in conjunction with accompanying drawing, the utility model is further described.

referencefig. 1, a kind of five-part form plate type heat exchanger, it is the one of plate type heat exchanger, this five-part form plate type heat exchanger is primarily of fixed plate body 1, upper beam 2, first, second, third, fourth central dividing plate 3,5,6,7, folding journey plate 4, movable plate body 8, front support rod 9, clamping screw 10, underbeam 12 form.By fixing, movable plate body 1,8, upper and lower beam 2,12 and front support rod 9 form framework, installs first, second, third, fourth central dividing plate 3,5,6,7 in this framework; Corrugated cardboard sheet 11 is arranged on fixed plate body 1, first, second, third, fourth central dividing plate 3,5,6,7, hang on upper beam 2 by suspension hook between movable plate body 8, upper beam 2 is hung simultaneously first, second, third, fourth central dividing plate 3,5,6,7, movable plate body 8 and corrugated cardboard sheet and seal gasket, with fishbolt 11 and nut, equipment clamping is made it into as a whole, seal and form medium channel, media of both sides is by corrugated cardboard sheet heat exchange.Heat transferring medium (liquid or gas) reverse flow in adjacent passage, carries out heat exchange.On anticorrosion, first, second, third, fourth central dividing plate 3,5,6,7 requires that stainless steel is coated, and fixed plate body 1, movable plate body 8 and front support rod 9 paint process, and other carbon steel part is zinc-plated.Just facing fixed plate body 1 when corrugated cardboard sheet 11 is installed, side flow process is 6 journeys, and the 4th section is 2 journeys; Opposite side the 4th section is 2 journeys, and other every section is one way.6 kinds of media can be realized work in an equipment simultaneously.

As shown in Figure 3, arrange folding journey plate 4 in being the 4th section between described 3rd, the 4th central dividing plate 5,3, its thickness is 5mm.Linear cut is shaping, and Linear cut surface wants level and smooth, must not have obvious fold.Two planes of folding journey plate are smooth, must not be uneven, and the depth of parallelism is not more than 3/1000, and perpendicularity is not more than 2/1000.

Folding journey thickness of slab of the prior art is generally at about 0.6mm, within about 3 years, crackle will be there is in use, under the operating mode that pulsation is violent, the time is shorter, cause internal leak, and the utility model adopt δ=5mm to roll over journey plate can the impact failure of effectively anti-fluid especially pulsating fluid, avoid the internal leak of equipment herein.The use of 5mm thick folding journey plate decreases the maintenance cost of equipment, extends service life.

The service life of rolling over journey plate with the impact resistance of the folding journey plate of 0.6mm in prior art and the thick folding journey plate of the utility model 5mm: δ=5mm is 8.3 times of the folding journey plate of 0.6mm, and the never simple multiple proportion of the raising of this shock resistance anti-shear ability in practical application, far away higher than this numeral.

Fixed plate body 1 of the present utility model needs welding lower margin and adapter, movable plate body 8 wants welded pipe; First, second, third, fourth central dividing plate 3,5,6,7 welds gasket ring, flanged plate and adapter, and weld the thick stainless steel of rear 1mm coated, coated requirement is tightly smooth, bulge must not be had, carbon steel part must not be had to expose, and level and smooth with adapter weld, postwelding is polished.

Front support rod 9 needs welding base plate, upper beam 2 needs to weld spindle nose, and underbeam 12 welds threaded block; Front support rod, upper underbeam and fishbolt process rear galvanized anticorrosive process.

Because the utility model is also a kind of plate type heat exchanger, so NM structure is all identical with existing plate type heat exchanger structure.

Generally, manufacture process generalization of the present utility model, standardization, simplifies, and to compress the production cycle, is convenient to manufacture.

Fig. 2 is flow chart of the present utility model.Heated medium enters from movable plate body 8, and fixed plate body 1 goes out, and makes full use of the waste heat of system, and medium segment is heated in batches, and wherein the 4th section is 2 journeys, and the requirement so both meeting Pressure Drop turn improves heat transfer coefficient simultaneously.Opposite side the 4th section is 2 journeys equally, and medium is entered by the second central dividing plate 5, and the first central dividing plate 3 goes out, and forms full countercurrent flow with by heated side, and improve heat transfer efficiency, other each section is one way, and the medium of this side totally 5 kinds of different operating modes, heats up piecemeal.If each section of both sides is all one way, reduce by one piece of central dividing plate, heat exchanger also becomes 4 sections, but cannot realize large discharge equipment resistance like this falls very little and heat transfer coefficient is very high requirement.
