Shell-and-tube heat exchanger claims again tubular heat exchanger, is to be enclosed in the wall of restraining in housing as the dividing wall type heat exchanger of heat-transfer area.This heat exchanger structure is simpler, and operation is reliable, and available various structural materials (being mainly metal material) are made, and can use under high temperature, high pressure, is present most widely used type.
Rubber cushion formula plate type heat exchanger is a kind of new type high efficient heat exchanger that is formed by a series of sheet metal closed assemblies with certain bellows-shaped.Form the thin rectangular shape passage between various plates, adopt the rubber cushion sealing between plate, carry out exchange heat by half sheet.Plate type heat exchanger is the ideal equipment that liquid-liquid, liquid-vapour carry out heat exchange.The characteristics such as it has that heat exchange efficiency is high, heat loss is little, advantages of compact and light structure, floor space are little, easy to clean is installed, be widely used, long service life.Under the uniform pressure damaed cordition, the high 3-5 of its ratio of heat transfer coefficient pipe heat exchanger times, floor space is 1/3rd of pipe heat exchanger, and heat recovery rate can be up to more than 90%.
Heat exchanger commonly used in prior art has shell-and-tube heat exchanger and rubber cushion plate type heat exchanger, for shell-and-tube heat exchanger: because flow is larger through its equivalent diameter of given flow area, thereby can only obtain lower film heat transfer efficiency; The identical equipment volume of heat transfer area is increased, and weight increases, and materials increase, thereby have improved equipment cost.And the rubber cushion plate type heat exchanger can produce complicated Fluid Flow in A owing to changing plate shape and spacing, can obtain on board-like heat-transfer area without the flowing of " dead band ", thereby pollutant adheres to less, and less scaling, the plate bundle is removable again, the equipment easy to clean.But pressure of equipment lower (being no more than 2.5MPa) heat transferring medium can not be inflammable, explosive substance, and medium can not be toxic.Due to the rubber cushion in use aging (being no more than 3 years) of sealing use, cause the equipment can not continuous operation.
The utility model content
For above-mentioned deficiency of the prior art, the utility model main purpose is to provide a kind of lamella heat exchanger, this outer cover of heat exchanger adopts shell-and-tube, and the heat exchanger core body employing is board-like, can eliminate common tube shell heat exchanger heat exchange efficiency low, the problem that floor space is large, the heat transferring medium that has overcome equipment in common plate type heat exchanger cannot toxicly have inflammable and explosive substances and the not high problem of equipment operating pressure.
For achieving the above object, the technical solution adopted in the utility model is: a kind of lamella heat exchanger, comprise tubular outer shell, pillar, heat exchange core body, described heat exchange core body is placed in described tubular outer shell, the described tubular outer shell of described shore supports and heat exchange core body, described heat exchange core body are the plate type heat exchanger core body, and described heat exchange core body comprises heat exchanger tube and a plurality of heat exchanger plates, described a plurality of heat exchanger plates is integrally welded, and described heat exchanger tube is located on described integrally welded a plurality of heat exchanger plates.Tubular outer shell described in the utility model lamella heat exchanger refers to the shell of common tube shell heat exchanger, also can design and produce according to actual operating position.Heat exchange core body described in the utility model is the plate type heat exchanger core body, but be different from common plate type heat exchanger core body, adopt rubber cushion to be tightly connected between the heat exchanger plates plate of common plate type heat exchanger core body, and in plate type heat exchanger core body of the present utility model between the heat exchanger plates plate for being welded to connect.
Preferably, described heat exchanger tube and described tubular outer shell are welded to connect.Be welded to connect between heat exchanger tube described in the utility model and tubular outer shell and be integral, good leak tightness not only, and high pressure resistant, service life is longer.
Preferably, the mouth of pipe of described heat exchanger tube is provided with flange.
Further, described flange is band neck W.N flange.The a kind of of pipe fitting with the neck W.N flange, refer to that W.N flange is not yielding, good seal with flange neck and that the pipe transition is arranged and that be connected with the pipe butt welding, be widely used, be applicable to pipeline that pressure or temperature fluctuate widely or the pipeline of high temperature, high pressure and low temperature.
Type of attachment between tubular outer shell described in the utility model and flange is full welding, and the benefit that adopts this connected mode is that heat exchanger is not easy to produce leakage, can satisfy working long hours of equipment.
Preferably, adopt laser weld between a plurality of heat exchanger plates in the heat exchange core body described in the utility model.Adopt laser weld to eliminate temperature difference heat stress between a plurality of heat exchanger plates, extend the service life of heat exchanger plates.To adopt between heat exchanger plates that to be welded to connect be the reliability that seals between heat exchanger plates in order improving, to satisfy heat exchanger at high temperature, high pressure, long-time reliably working under the operating mode of deep-etching.
Preferably, described tubular outer shell is tubbiness.
In order to make lamella heat exchanger described in the utility model can satisfy use poisonous, inflammable medium, the flange of the mouth of pipe of described heat exchanger tube adopts band neck W.N flange, with bolts between flange, wherein flange encircles the compounded flexible graphite pad with the interior ring of pad employing band and centering during external equipment is connected, this Graphite pad has improved the reliability of equipment ferrule, and gasket seal does not produce sealing leak when the equipment operating pressure is high.
The beneficial effects of the utility model are: lamella heat exchanger heat exchange efficiency of the present utility model is high and floor space is little, can be used in the heat exchange of toxic inflammable and explosive substances medium, and the equipment operating pressure is higher.
