Description
Technical field
The utility model relates to a kind of condenser, be particularly related to a kind of dry type and freeze condenser, the air-flow that contains water vapour and other condensable gas is freezing on the cold-producing medium tubulation of condenser to be sublimated to become solid, remaining incoagulable gas is pumped, and can greatly reduce the rate of air sucked in required that enters follow-up vacuum system.This dry type is freezed condenser and be can be used for for food processing, medicine, chemical field.
Background technology
In vegetable oil refining process, generally need to reach one-level product oil index through deodorization procedures, deodorization completes conventionally in deodorizing tower, treats that deodorised oil removes stink substance by steam distillation under high temperature and high vacuum condition.According to Dalton's law (of partial pressures), in deodorising process, the absolute pressure in deodorizing tower is lower, be more beneficial to the volatilization of stink substance in vegetable oil and remove, so deodorizing tower is all supporting a pumped vacuum systems.But, the gas of discharging from deodorizing tower, contain the condensable gas such as a large amount of water vapours and aliphatic acid, cause pumped vacuum systems load very large.
For reducing the load of pumped vacuum systems, conventionally adopt and first mist is sent into and freezed in condenser, the condensable gas such as water vapour and aliphatic acid are freezed to remove, remaining incoagulable gas enters vacuum-pumping tube, greatly reduces the load of pumped vacuum systems.
Of the prior artly freeze the cylindrical shell that condenser comprises axis horizontal, one end of cylindrical shell is sealed by tube sheet, be fixed end socket sealing of the other end, many U-shaped cold-producing medium tubulations are installed on tube sheet, each U-shaped cold-producing medium tubulation extends to fixed seal head end along the axis of cylindrical shell, and tube sheet outer side covers has flange end socket; Inner chamber along cylindrical shell is provided with multiple tracks deflection plate, and tail gas air inlet is positioned at one end of cylindrical shell, and bleeding point is positioned at the other end of cylindrical shell.This freezes condenser when work, and mist enters from tail gas air inlet, along the length direction complications of cylindrical shell, advances, and residual gas is discharged from bleeding point.In the direction of advance of gas, each condensation chamber being divided into by deflection plate is the equal of series relationship, owing to just entering in the gas that freezes condenser, condensable gas content is the highest, and larger near the condensation chamber load of tail gas air inlet, piece and solid fatty acid are covered with ice rapidly on cold-producing medium tubulation; And away from the condensation chamber of tail gas air inlet because remaining condensable gas amount significantly reduces, freeze load lighter; And the arrangement of the cold-producing medium tubulation of each condensation chamber is identical, often cause condensation chamber to be above covered with ice, breathing area significantly reduces, need to stop continuing to freeze then enter ice-melt program, and condensation chamber is below now also more empty, shorten on the whole the work period of freezing condenser, caused that to freeze the operating efficiency of condenser lower, can not give full play to congelation.
Utility model content
The purpose of this utility model is, overcomes problems of the prior art, provides a kind of dry type to freeze condenser, freezes efficiency high, and the work period is long.
For solving above technical problem, a kind of dry type of the present utility model is freezed condenser, the cylindrical shell that comprises axis horizontal, one end of described cylindrical shell is sealed by tube sheet, be fixed end socket sealing of the other end, many U-shaped cold-producing medium tubulations are installed on described tube sheet, each U-shaped cold-producing medium tubulation extends to described fixed seal head end along the axis of cylindrical shell, described tube sheet outer side covers has flange end socket, it is characterized in that: the front side of described cylindrical shell is provided with the arc forwards protruding and expands shell, on the front end face of described arc expansion shell, be evenly distributed with at least two tail gas air inlets, described in each, the axis of tail gas air inlet is horizontal and perpendicular to the axis of described cylindrical shell, length direction along described U-shaped cold-producing medium tubulation is disposed with the tube bundle support baffle plate parallel with described tube sheet and a plurality of tube bundle support dividing plate, described in each, between tube bundle support dividing plate, form respectively one time condensation chamber, between described tube bundle support baffle plate and described tube sheet, form time condensation chamber, the front end of described time condensation chamber and an adjacent condensation chamber are mutually isolated, between the rear end of described time condensation chamber and each condensation chamber, by bleed-off passage, are interconnected, the housing of described time condensation chamber is provided with bleeding point and is connected with exhaust tube.
With respect to prior art, the utility model has been obtained following beneficial effect: (1) mist enters in arc expansion shell from tail gas air inlet, enter respectively each condensation chamber simultaneously, after freezing, each condensation chamber removes most of condensable gas, residual gas enters the bleed-off passage at each condensation chamber rear jointly, through bleed-off passage, enter the further condensing, freezing in time condensation chamber, remove remaining condensable gas, finally from bleeding point, discharge incoagulable gas.(2) between each condensation chamber, be equivalent to parallel connection, the effect of freezing is identical, and the overall length and the gross area that freeze condenser are fully utilized, and between condensation chamber and time condensation chamber, is equivalent to connect, carry out time condensation and check on, guarantee fully charge residue condensable gas.Due to the contact of condensation chamber be the highest gaseous mixture of condensable gas content, therefore a condensation chamber parallel connection is provided with a plurality of; After a condensation chamber freezes, residual condensable gas seldom, only needs a time condensation chamber that area is very little, makes cold-producing medium tubulation all can bring into play well effect in overall length direction.(4) each condensation chamber is arranged in parallel, and front face area is large, and windage is little, and each condensation chamber can freeze fullly simultaneously, there will not be some frozen fullly, and all the other are vacant very large phenomenon still, and the work period is long; More can not occur to block because of the place ahead, make air-flow be difficult to flow to the phenomenon at rear.
