Description

Stain-resisting pattern contacting turret board composed with mutiple elements

What the present invention relates to that a kind of mass transfer and heat transfer unit (HTU) use contacts column plate, especially a kind of anti-soil type multicomponent combination contact column plate that is applicable to distillation with the system of filthy material.

Current mass transfer and the heat transfer unit (HTU) that is used for the liquid distillation especially as being used for organic chemistry industrial treatment fermentation liquid wine with dregs towers such as alcohol, butanols, acetone, continued to use the typical circular bubble cap tray mostly.This template complex structure, its castellated edge very easily collude hangs fiber-like impurity, and again because of circular-cap tower superficial linear velocity in a column is low, therefore each position is very easily by obstructions such as silt particle, weeds onboard, and antifouling property is poor, often need stop tower, tears tower open, draw tower.Simultaneously, because Peng Pao carries out in the edge of bubble-cap, interfering with each other between bubble-cap is big, and air-teturning mixed phenomenon is serious, inferior separating effect, and specific productivity is low.And because the material time of staying onboard is long, in tower, very easily carry out new chemical reaction, generate new organic impurities, unfavorable to product quality.The counter direction jet trays of employing, valve tray etc. are also arranged, hang fiber-like impurity but also very easily collude, stifled tower phenomenon is also extremely serious, and these plate columns reach the bad adaptability to load variations to objective condition (fluctuation often stops vapour, power failure etc. as vapour pressure), operating flexibility is little, therefore seldom uses.Also have and use S shape element column plate, but this column plate very easily forms dead band or slow district or by-pass flow district at two side peripheries and semilune position.Less than normal, the vapour-liquid loose contact of gas speed influences the utilization of separating effect and column plate effective cross-section in these zones, and simultaneously because impulsive force is poor, foreign material deposit easily and cause stifled tower.

In view of existing problem in the prior art, the purpose of this utility model is to provide a kind of simple in structure, handling ease, good separating effect, be difficult for precipitated mud and sand impurity, be difficult for colluding hang fiber sundries be suitable for contain solid shape suspension of volume and the filthy system that has certain viscosity distillation contact column plate.

To achieve these goals, solution of the present utility model is as follows.Contact column plate of the present utility model comprises base plate, and the liquid element falls in main stream-liquid contact member.In the utility model, adopt almost isometricly, have smooth bubble and blow the limit and, place them the column plate centre as main stream-liquid contact member than the crosslinked formation liquid bath of the mutual socket of S shape element, Steam Pipe and the bubble-cap of the steering angle of long radius several.On two semilune zones at the axial two ends of main stream-liquid contact member on the base plate, use the bubble-cap element as time gas-liquid contact element again.Preferably select the D shape or the semi-moon shaped bubble-cap conduct time gas-liquid contact element that has than atmosphere speed of two similar English alphabets " D " for use,, improve the purpose of column plate effective rate of utilization and separating power to reach the activation edge dead band and to strengthen slow district, both sides.In order to guarantee that vapour-liquid stream is the downbeam operation, all seal and fix at the two ends of main stream-liquid contact member S shape component assembly with end-plate, on end-plate, can offer some apertures or inclined hole to increase the gas-liquid contact.In order further to improve plate efficiency and vapour-liquid flux, can on the back of S shape element and semilune bubble-cap element, offer several guiding again and advertise the hole.

Contact column plate of the present utility model owing to adopt isometric substantially S shape element as main stream-liquid contact member, makes manufacture simplification; Since adopt the smooth bubble of tool blow limit and long radius steering angle S shape element and as time vapour-liquid contact element be the fairshaped semilune bubble-cap of tool element, colluded extension so material is difficult for quilt, flow resistance is little; Owing to adopted inferior vapour-liquid contact element, the effect of main stream-liquid contact member is replenished, improved column plate cross section effective rate of utilization; Because gas when rising the gas passage and enter column plate, basically forms single way jet, make material all towards falling that the liquid component orientation moves and dirty.And the percent opening of contact column plate of the present utility model is big, is higher than about one times of column plate commonly used, the gas speed about employing is twice than common bubble column in the tower, so the vapour-liquid flux is big, liquid stream has stronger driving force, and the antifouling property of column plate is good; Because material is one-way flow on column plate, the material lagging time is short again, and essentially no air-teturning mixed phenomenon is difficult for causing new chemical reaction and generates new chemical substance, has improved separating effect, has improved product quality.

Contact column plate of the present utility model also can be made the usefulness of the rectifying of general liquid phase chemical material except that the distillation that is applicable to the system of filthy material.
