Abstract
The invention relates to a unit of a chemical material vacuum distillation tower, aiming at providing a sparge liquor distributor or a sparger. The low tower resistance distributor of the invention is made in a high annular shape and closely installed inside a tower wall, which is provided with an opening on the upper end, a soleplate on the lower end and a big end up annular cavity between the inner wall and the outer wall and used for storing liquid. A feed inlet is arranged on the tower wall at the place where the cavity is formed. The upper cut of the inner wall is a channel for the airflow inside the tower. The diameter of the upper cut is 80-90 percent of the inner diameter of the tower. Holes or nozzles that distribute based on a certain discipline with different sizes, lengths and directions designed based on technological requirements are distributed on the inner wall and the soleplate of the distributor. The distributor of the invention makes the airflow channel in the tower preserve a relatively large sectional area, resulting in smooth flow of the uprising gas with relatively low resistance and that more liquid can be held to amortize the change of flux, thereby leading to stable and ongoing flux of the sparge liquor. The design of the nozzles facilitates the sparge liquor to spray evenly on each point in the tower with different flux.
Description
Technical field
The present invention relates to a kind of device of chemical material vacuum (distilling) column, specifically relate to a kind of spray liquid distributor that is applied to vacuum (distilling) column, or claim spray thrower.
Background technology
The vacuum (distilling) column of chemical material is because pressure is lower, and is very responsive to tower body pressure differential up and down.If the resistance of gas flow is big in the tower, make destilling tower top and bottom pressure reduction bigger than normal, tower still temperature drift often, still liquid is crossed the one of the main reasons of thermal metamorphism.
Therefore in addition, the vacuum (distilling) column of chemical material is because diameter is bigger, and the even spray to the fractional distillation filling-material of its inside requires just higher.This uniform implication not only be meant on the space evenly, and refer to temporal evenly, promptly require the stability of flow of spray liquid and uninterrupted.
At present, the spray liquid distributor that generally is used to spray often is designed to dendroid, and this will occupy sectional area too much in the destilling tower, thereby increases the resistance of gas flow in the tower, and the destilling tower operation index is degenerated.And the distribution of the spray liquid of this class distributor on the sectional area of whole tower also is not easy evenly.
In addition, because the liquid material that sprays on the rectifying column is gone into toward renaturation, periodic infusion by plunger pump, membrane pump, piston pump etc. often, or the tower still of preposition rectifying column comes by the Liquid level adjusting valve discharging, therefore, the mass flow that enters liquid distribution trough usually is intermittent or unstable or even is interrupted.General liquid distribution trough also can't solve spray mass flow problem of unstable at present.
Summary of the invention
The objective of the invention is to overcome deficiency of the prior art, a kind of low tower resistance that can be applicable to vacuum (distilling) column is provided, is evenly distributed and has the flow pooling feature spray liquid distributor (or claiming spray thrower).
The low tower resistance distributor that has pooling feature in the vacuum (distilling) column among the present invention is high annular, and attached subsides are installed in tower wall inboard; Its upper end open, there is base plate the lower end, forms the cavity of a up big and down small annular space liquid storage between inside and outside wall; The tower wall at this cavity place is provided with material inlet; The suitable for reading of inwall is the passage of air-flow in the tower, and diameter suitable for reading is 80～90% of a tower internal diameter; Hole or nozzle by the different sizes of technological requirement design, different length, different directions and certain regularity of distribution are arranged on distributor inwall and the base plate, and spray liquid can be sprayed onto each point in the tower equably when making different flow.
The height of distributor is 0.5～2 times of vacuum (distilling) column internal diameter.
This distributor has bigger volume and height; When adopting the periodically pump of discharge opeing, for example plunger pump, membrane pump, piston pump etc. are to the tower injecting material, or during the intermittent or unstable discharge opeing of preposition rectifying Tata still, enter that liquid in the distributor can be detained and flow obtains buffering in distributor, make spray liquid stability of flow and uninterrupted.
Distributor of the present invention (with reference to the accompanying drawings) has bigger height, is affixed in the destilling tower wall, its outer wall is the tower wall, and inwall is up-small and down-big frustum face, and the suitable for reading of inwall is the passage of air-flow in the tower, diameter suitable for reading can be designed as 80～90% of tower internal diameter, so gas-flow resistance is less; Form up big and down small annular space between inside and outside wall, its upper end open, there is base plate the lower end.Constitute the cavity of a liquid storage between the inside and outside wall of distributor and the base plate, the tower wall at this cavity place is provided with material inlet.
Have the spray liquid hole on the inwall of distributor and the base plate, on the hole of inwall nozzle be installed, the nozzle of thin tube-like from top to bottom successively annular distribution on inwall.The length of nozzle designs according to certain rules, makes distributor can both evenly spray the whole area of tower when different liquid level; Nozzle welds or is bolted on the inwall of distributor, and nozzle has reclinate end.
Compared with prior art, beneficial effect of the present invention:
Distributor designs of the present invention becomes high annular, and attached subsides are installed in tower wall inboard, makes the interior gas channel of tower still keep bigger sectional area, and uprising gas flows unobstructed, and resistance is lower; The liquid storage cavity of distributor has bigger volume, can hold the variation of more liquid with buffer traffic, makes spray liquid stability of flow and uninterrupted.Distributor has distributed by the nozzle of the different length of predetermined design at differing heights, makes spray liquid can both be sprayed onto each point in the tower equably when different flow.
Description of drawings
Fig. 1 is a distributor scheme of installation in the present embodiment;
Fig. 2 is a nozzle scheme of installation in the present embodiment;
The specific embodiment
With reference to the accompanying drawings, be described in detail below:
Distributor (see figure 1) in the present embodiment, comprise young under the ratio suitable for reading, be the planar inwall of the frustum of a cone, the back cut diameter of inwall equals about 90% of tower diameter; Constitute the inner chamber of a liquid storage between distributor inside and outside wall and the base plate, the upper end open-ended, the outer wall at inner chamber place is provided with material inlet; There are a series of spray apertures to spray material on the base plate; Successively annular distribution is on inwall from top to bottom for plurality of nozzles, and the length of nozzle distributes according to certain rules, makes material at different flow, and promptly the liquid level in the inner chamber all can evenly be sprayed onto on the cross section of tower not simultaneously; Nozzle has reclinate end.
The distributor inwall can also be suitable for reading identical with the end opening size among the present invention, is cylindric.
In the present embodiment, nozzle is the (see figure 2) that is bolted on the inwall, and convenient disassembly is easy to change.Also can adopt the fixed form of welding.
At last, it is pointed out that also above what enumerate only is specific embodiments of the invention.Obviously, the invention is not restricted to above embodiment, many distortion can also be arranged.All distortion that those of ordinary skill in the art can directly derive or associate from content disclosed by the invention all should be thought protection scope of the present invention.
