Abstract
A self-suction strip bubble cap distillation tower is formed by combining a steam injection device 3 and an A-type section strip bubble cap tower plate 1. It is heated instantaneously by sucking feed liquid continuously through the steam jet device 3, and forms fine liquid drops of the feed liquid by utilizing the kinetic energy of the steam for distillation. The column plate is a one-way bubble blowing side A-shaped section bar-shaped bubble cap column plate 3, and the liquid phase can be pushed to a downcomer by utilizing the phase disturbance power, so that the separation effect is achieved. The utility model discloses simple structure, energy consumption are low, feed liquid dwell time is short, recovery concentration is high, the separation is effectual in the tower cauldron, are applicable to the feed liquid that the distillation has certain viscosity, can be applied to chemical industry, biology and pharmacy trade widely.
Description
Technical field
The utility model relates to a kind of distilling apparatus, relates in particular to a kind of distilling apparatus that is applicable to solvent recovery or solvent distillation.
Background technology
In biological and chemical industry, extraction is basic operating unit, and the field has a wide range of applications.But the distillation of extraction back solvent recovery or solvent often has influence on yield, quality and the cost of product.The distillation equipment of existing common employing is generally single-action or multiple-effect concentrator, concentrates and reclaim still and alcohol distillation tower.But when biology is extracted as the thermal sensitivity feed liquid, to the requirement of the temperature and the time of staying with regard to suitable strictness.The above two equipment is that vacuum concentration equipment is not high to the low boiling point solvent rate of recovery, and does not have rectifier unit, and the concentration of the solvent that obtains is general only about 50%.And for the alcohol distillation tower, increase on concentration, but feed liquid overstand in the tower still causes active material oxidation in the feed liquid easily.Above-mentioned three kind equipments are concentrating or distillation has in plant polyose, the saponin class feed liquid process, also very easily occur drawing bubble, rush to summit, run phenomenon such as material.
Summary of the invention
In order to solve above problem, the utility model provides a kind of processing and manufacturing simple in structure, easy, and energy consumption is low and feed liquid time of staying in the tower still is short, solvent recovery concentration height, good separating effect, the destilling tower that is difficult for rushing to summit.
For achieving the above object, the utility model adopts a kind of self-priming bar shaped bubble-cap tower, and this device comprises: tower still, tower body, steam injection equipment and several A type cross section bar shaped bubble cap plate.
Steam injection equipment comprises: jet chimney, steam jet, negative pressure cavity, injector and mixed again section.Steam jet is connected with jet chimney by flange, is positioned at the negative pressure cavity that the contraction section of injector is connected, and negative pressure cavity one side is provided with charging aperture.Steam jet is made up of contraction section and expansion segment, and injector is made up of contraction section, mixer, expansion segment.Tower still bottom is provided with the auxiliary steam heater.
Its operation principle is: when the working steam of certain pressure is by steam jet in the jet chimney through shrink and expansion after with high fast direction injector, pressure in the negative pressure cavity is sharply descended, reach vacuum state, feed liquid promptly is inhaled in the negative pressure cavity through charging aperture, and confuses high-temperature steam and enter injector together.Injector is a De Laval noz(zle) that designs on hydrodynamics and thermal conduction study basis, and it is made up of contraction section, mixer and expansion segment, obtains enough heat and jet velocity to guarantee feed liquid.Contraction section is generally made internal conical surface or inner ring surface, and its effect is to make feed liquid penetrate suction.The process that feed liquid enters a straight mixer is the process of a homogeneous, even the speed of feed liquid, temperature reach even distribution.Feed liquid through expansion segment and mix again section its mainly to act on be to make the feed liquid dynamic head transfer hydrostatic head to, when feed liquid being overcome mix the section resistance again, speed and temperature field are further evenly distributed.
Feed liquid by moment mixing, the heating of injector, again by steam injection equipment ejection and atomizing, makes the volatile substances in the feed liquid obtain rapidly vaporizing in the tower still under the carrying secretly of steam as from the foregoing, has created fabulous condition for entering distillation process.
In addition,, can open this device, give supplementary heating, before feed liquid enters distilling period enough evaporation heats be arranged to guarantee to atomize if the situation of atomizing feed liquid evaporation heat deficiency is provided with the steam assisted heating device in the bottom of tower still.
A type cross section bar shaped bubble cap plate comprises: tower tray, main vapour-liquid two-phase contact element, inferior vapour-liquid two-phase contact element and fall the liquid element and form.Main vapour-liquid two-phase contact element is arranged at the tower tray middle part, be that several rectangles rise the A tee section bar shaped end-blocking bubble-cap that steam ports and several unidirectional bubbles blow the limit and form a team to be welded, inferior vapour-liquid two-phase contact element is arranged at dead band, the main stream-liquid contact member left and right sides, be two and arcly rise the arc bubble-cap of A tee section that steam ports and unidirectional bubble blow the limit and form a team to be welded, the front and back configuration liquid receiving area of main stream-liquid contact member and fall the liquid element.
The tower tray percent opening of this column plate is higher than more than 1.5 times of bubble cap plate commonly used, and the vapour-liquid flux is big, and antifouling property is good.Usually column plate liquid flow form is one-way process (single current), therefore bubble-cap being designed to unidirectional bubble here blows the limit, can form vectored injection like this, can utilize alternate perturbed force to push liquid phase to downspout thus, to reduce air-teturning mixed phenomenon and liquid holdup time on column plate, improve separating effect.
Above distilling apparatus has overcome preferably in still-process that feed liquid time of staying in the tower still is long, and energy consumption is low, the problem that the while has also solved when distillation has plant polyose, saponin class feed liquid easy-to-draw bubble preferably, rushed to summit, runs material.Simple, the easily processing and manufacturing of this device structure, energy consumption is low, is applicable to the distillation equipment that has the distillation of certain viscosity feed liquid.To be with a wide range of applications at chemical industry, biology and pharmaceutical industry.
