Compared with prior art, the utility model has the following advantages:
One, under rational version, heat exchange is enhanced;
Due to contact and the rough surface peening disturbance of two side liquids, because this enhancing heat exchange efficiency; Meanwhile, do not have contact point and plate effects on surface not to have spike angle point due between plate pair, passage is more penetrating, and gas can not be made to occur short circuit phenomenon.
Two, sheet structure parameter can flexible modulation, and accommodation is wider;
According to different working condition requirements, can flexible modulation distance between plates, plate to spacing and contact density, reach heat transfer effect in various degree; Meanwhile, sheet form can be straight plate, and also can be arc, difform plate can also have different arrangement forms.Therefore, this plate-type reactor can adapt to the solution-air of differential responses characteristic and heat transfer requirements, gas-solid, the reaction of the forms such as liquid-liquid.
Three, reduce the equipment volume of same treatment amount, be conducive to equipment enlarging;
In this New-type plate reactor, the free air space of reaction mass and catalyst is shell side, and heat transferring medium is plate journey.In gas-solid phase reaction, in conventional shell and tube reactor, tube side walked by reaction mass and catalyst, heat transferring medium walks shell side, these two kinds different types of feed make when same treatment amount, this novel device volume is obviously little than shell and tube reactor, whole equipment is compacter, is conducive to the maximization of reactor.In liquid phase or gas-liquid-solid phase reaction, heat exchange element in conventional bubble tower or paste state bed reactor is calandria, around tubular type, shell and tube or needle type fin tubular type, there is heat exchange area little, take the shortcoming that equipment volume is large, the plate type heat exchanging element adopted in this New-type plate reactor has compact conformation, advantage that heat exchange area per unit volume is large, thus making heat exchange amount large, equipment volume is little, is also conducive to the maximization of reactor.
Four, reaction mass and catalyst (containing catalyst reaction) are in shell side circulation, are convenient to distribution and handling;
Due to the high heat exchange efficiency of this heat exchanger plates, usually by heat transferring medium limp journey, shell side walked by reaction mass, therefore can while guarantee heat transfer effect, increase filling and free air space, simultaneously because shell side space is more penetrating, be therefore convenient to distribution and the handling of reaction mass and catalyst.
Five, compact conformation, less scaling, be convenient to cleaning;
Whole heat exchange element is connected with housing is compact, without the need to much complex interface; Because contact exists, and fluid liquid form is turbulent flow, therefore produces boundary shear stress comparatively large, makes heat exchange element itself have self-cleaning function; Meanwhile, relatively penetrating shell side walked by reaction mass, is convenient to cleaning.
