SU1565494A1 - Counter-flow column for adsorption cleaning - Google Patents

Abstract

The invention relates to equipment for the oil and fat industry, can be used in the cleaning of vegetable oil miscella, and prevents the destruction of the sorbent, the blocking of flow areas and the formation of stagnant zones. The goal is to intensify the adsorption process. The column consists of a body (K) and loading and connecting (C) pipes. Inside the K and C pipes are installed perforated shipping augers. At the exit section of the loading tube, a ring shell coaxially fixed, connected to the C pipe by a pipe. The collector K is equipped with spray nozzles for supplying miscella. 1 hp f-ly, 1 ill.

Description

SUBSTANCE: invention relates to equipment for fat-and-oil industry and can be used for purification of crucible oils

The purpose of the invention is to intensify the process of adsorption

Equipping the columns with perforated conveying augers in aggregate with the location of the Myslelite output collector at the outlet section of the loading tube makes it possible to increase the area and time of interaction between the liquid and the sorbent; the presence of nozzles - to introduce a uniform introduction of liquid into the reaction zone

The drawing shows the proposed countercurrent column

Countercurrent column for adsorption cleaning, mainly oil miscella, consists of a vertical cylindrical body 1 boot vertical

No 2 and connect it to the horizon pipe 3 The court with 1 has a single one that has two trays connected to the bottom of the trunk 4 corp. I installed a perforated transport screw 5 and in the upper part of the furnace, a sorbent extraction unit consisting of a discharging device 6 and a chute 7 Cros / corpus 1 can be equipped with a gasoline supply 8

The boot-load 2 has 9 in the switchgear and the displacement organ 10 is located on track 2, the patchbka 11 pot should also be installed, here and in

Inside the connecting 3 mill, a perforated protractor and and a screw 12 Connector of the output of the miscella are more complete in the form of a casing shell 13 coaxially mounted on the output section

loading pipe 2. The shell 13 is in communication with the connecting pipe 3 by means of a connecting pipe 14. Inside the annular shell 13, an annular drainage screen 15 is installed, and on the shell 13 there is a pipe 16 for diverting the miscella.

Countercurrent column works as follows.

The sorbent, such as silica gel, through the funnel of the hopper 9 and the vertical loading pipe is loaded into the screw 12 of the pipe 3, which during rotation moves it along the connecting pipe 3 into the vertical cylindrical body 1, then the screw 5 moves the sorbent upwards with a certain speed. The sorbent is unloaded by a special unloading device 6, which discharges the sorbent into the chute 7.

The miscellar enters the collector with nozzles 4 and is filtered through a layer of sorbent. At the same time, the sorbent absorbs undesirable impurities from the miscella that flows down and, after passing through the connecting pipe 3, rises through the nozzle 14 and leaves the column through the drainage grid 15, the annular shell 13 and the nozzle 16 .

The supply of leaching gas through pipes 11 and 8 helps to increase the flowability of the sorbent. The column does not require compaction of the sorbent layer, which leads to the deformation of the sorbent granules, an increase in hydrodynamic resistance and a decrease in the efficiency of the process. In the cotton oil purification column in the form of miscella, the destruction of the sorbent grain, the occurrence of press fittings, and the increase in hydrodynamic resistance are eliminated, as a result of which the speed of the miscella passes through the sorbent layer is significantly increased. The efficiency of the column is improved by ensuring uniform sorbent compaction and “Dead layers of sorbent near drainage.

The establishment of a coaxial vertical loading pipe 2 of the annular shell 13 with the grid 15 allows combining the loading operation of the sorbent with the cleaned

on the one hand, silica gel is supplied to the connecting pipe 3, and on the other hand, the miscella from the annular space between the loading tube 2 and the pipe 14 is led out through the drainage grid 15 and the pipe 16. wetting the silica gel, i.e., its deaeration, which allows to intensify the adsorption process.

The location of the end of the loading pipe 2 at the level of the sorbent in the connecting pipe 3 ensures the dosing of the sorbent, which helps to maintain a constant level of the sorbent in the connecting pipe 3. This design eliminates the entrainment of silica gel with the purified miscella. To intensify the process of impregnating the sorbent with miscella, the screws 5 and 12 are made perforated
