Abstract
A kind of vertical helical deflection plate condenser that is used for film condensation is made up of parts such as housing, fixed tube sheet, condenser pipe, helical baffles, spoiler, distance sink tubes.This condenser adopts vertical structure, and deflection plate adopts helical baffles, has a plurality of semicircle lyophobies hole on every helical baffles plate face, and lyophoby hole opening is at the place, outer near the inner walls helical baffles.When condensate liquid flows down from the condenser pipe surface from top to bottom by gravity, also be subjected to the promotion of the mobile steam of helical form, under the double action of gravity and centrifugal force, in time from the lyophoby hole, flow down step by step swimmingly, attenuate as the thickness of the liquid film of condensation process control thermal resistance, condensation coefficient is greatly enhanced.The utility model is reasonable in design, does not have the heat transfer dead band, and resistance is little and heat transfer efficiency is high, is a kind of comparatively desirable shell and tube condenser.
Description
One, technical field
The utility model relates to a kind of condenser, is a kind of vertical helical deflection plate condenser specifically.
Two, background technology
Condenser is the commonplace gas of petrochemical industry, chemical industry and commercial Application such as metallurgy, electric power, liquid heat-exchange apparatus.Conventional condenser adopts the segmental baffle structure usually, and pressure drop is big and have the zone that remains in a standstill, and energy consumption is big and heat-transfer effect is not good.In addition, when air-flow is restrained with bigger velocity shock, can cause the vibrations of pipe inevitably, cause the fracture of condenser pipe and tube sheet weld.
What condenser was different with other heat exchanger is: whole heat transfer process is accompanied by the condensation of thermal medium steam all the time.When the lower heat exchanger tube tube wall of saturated vapor and temperature contacted, steam was emitted latent heat, and at the tube wall external cooling liquid that congeals into.The steam condensation is divided into film condensation and dropwise condensation dual mode, and industrial what relate to is film condensation mostly.
After so-called film condensation is the wetting tube wall of condensate liquid, on wall, form the complete liquid film of one deck.Follow-up steam condensation can only be carried out on the surface of liquid film, that is to say the latent heat that the steam condensation is emitted, and must just can pass to cold wall by liquid film.Because the heat transfer coefficient of the heat transfer coefficient relative vapor condensation of liquid film is much smaller, thermal resistance is relatively large, so outer this layer liquid film of tube wall just become the main thermal resistance of condensing heat-exchange.In the conventional levels shell and tube condenser, to following when respectively arranging, liquid film all can progressive additive from top each current drainage for condensate liquid, below the heat transfer conditions of pipe to be subjected to very big influence, and more to row's influence down more for serious.If the shell and tube condenser of routine is changed into vertical, horizontal because of the segmental baffle of routine, condensate stream is long and do not have a lyophoby measure through road, and liquid film also can progressive additive, can have a strong impact on heat-transfer effect equally.Just because of this, the exploitation of all efficient condensers is at present all carried out round the thickness of attenuate liquid film bar none.For example adopt plain tube, surface coating, pyrolytic coating metal material etc.But said method or because of effect is obvious inadequately, or higher because of complex process, cost, and commercial Application is not general.Therefore, develop a kind of high-efficiency condensation equipment and just become the task of top priority.
Three, summary of the invention
The utility model relates to a kind of vertical helical deflection plate condenser that is used for film condensation.Constitute by parts such as housing, fixed tube sheet, condenser pipe, helical baffles, spoiler, distance sink tubes.This condenser adopts vertical structure, it is characterized in that deflection plate adopts helical baffles, has a plurality of semicircle lyophobies hole on every helical baffles plate face.Lyophoby hole opening is at the place, outer near the inner walls helical baffles.When condensate liquid flows down from the condenser pipe surface from top to bottom by gravity, also be subjected to the promotion of the mobile steam of helical form, under the double action of gravity and centrifugal force, in time from the lyophoby hole, flow down step by step swimmingly, attenuate as the thickness of the liquid film of condensation process control thermal resistance, condensation coefficient is greatly enhanced.
Vertical helical deflection plate condenser is a kind of very promising novel tubular heat exchanger.Shape is mobile in the shape of a spiral at shell side for fluid, has eliminated the heat transfer dead band that traditional segmental baffle board heat exchangers exists, and has reduced pressure drop greatly, has improved heat transfer efficiency.The helical form of steam flows, and has avoided the vibrations that produced when fluid cross is impacted tube bank in the segmental baffle board heat exchangers in the past.Because screw can be decomposed into circular motion and axially-movable, the liquid film that forms after the steam condensation in fact also is subjected to a kind of downward motive force of steam, and gas speed is bigger, and this motive force is just bigger.Under the double action of this motive force and gravity, flowing liquid arrives at the intersection of heat exchanger tube and helical baffles plate face very soon on the tube wall, then under action of centrifugal force, got rid of outer apace to the helical baffles that has certain tilt angled down, flow down step by step along the lyophoby hole on the plate face, thereby suppressed the speed that liquid film generates to greatest extent, condensation heat transfer film coefficient is increased greatly, improved condensation heat transfer speed.

Fig. 2 is a helical baffles lyophoby pore structure schematic diagram.
Five, the specific embodiment
By Fig. 1, Fig. 2 as can be seen, the utility model mainly is made of housing (1), fixed tube sheet (2), condenser pipe (3), helical baffles (4), spoiler (5), distance sink tube parts such as (6).On housing, be provided with vapour inlet (7), fixed gas outlet (8), liquid phase inlet (9), liquid phase outlet (10) and condensate outlet (11), discharging hole (12) etc.Helical baffles (4) is formed helical body with spoiler (5) drift angle overlap joint.Helical baffles (4) is fixing by distance sink tube (6), and condenser pipe (3) passes one by one from helical baffles (4), the support that helical baffles (4) and fixed tube sheet (2) are together restrained as condensation.
Helical baffles (4) can form by the mold time processing, and some deflection plates can divide into groups to hole simultaneously.Take all factors into consideration with cutting down finished cost from augmentation of heat transfer, the deflection plate number of every group of spiral should be good with 4 between 2～6 usually.
The number that every helical baffles (4) is gone up the lyophoby hole is 3～5, is shaped as semicircle, and the size of lyophoby hole (13) and concrete number are decided on process conditions.
Steam should be selected and the liquid film co-flow, and promptly direction flows from top to bottom.Frictional force between steam and the liquid film is quickened liquid stream at this moment, the liquid film attenuate, and condensation coefficient increases.
