(54) ПРОТИВОТОЧНЫЙ ИОНООБМЕННЫЙ АППАРАТ(54) TRAFFIC ION-EXCHANGE APPARATUS

II

Изофетение относитс к аппаратам дл непрерывного проведени процессов между раствором и ионообменной смолой.Isophilication refers to apparatus for the continuous conduct of processes between the solution and the ion exchange resin.

Известен противоточный ионообменный аппарат, содержащий вертикальный корпус, нижнюю дренажную решетку с отверстием , загрузочное устройство с загрузочной трубой и разгрузочное устройство с эжектором и два пульсатора соA countercurrent ion-exchange apparatus is known, comprising a vertical body, a lower drainage grate with a hole, a loading device with a loading tube and a discharge device with an ejector and two pulsators with

всасывающим и нагнетательным трубоН1 .suction and discharge pipeN1.

Недостаток известного аппарата заключаетс в том, что увеличение высоты попгьема приводит к уплотнению иониТа ,и к его повышенному износу.A disadvantage of the known apparatus is that an increase in the height of the popgie leads to compaction of the ionite, and to its increased wear.

Цель изобретени - повысить эффективность работы аппарата путем уменьшени износа ионита и дополнительно обводнить загружаемый ионит.The purpose of the invention is to improve the efficiency of the apparatus by reducing the wear of the ion exchanger and further irrigate the charged ion exchanger.

Поставленна цель достигаетс тем, . что загрузочное устройство выполнено в виде инжектора, нагнетательна труба которого соединена с отверстием дренажной решетки ri сопло - с нагнетательнымThe goal is achieved by that the loading device is designed as an injector, the injection pipe of which is connected to the drainage grate ri nozzle - to the discharge

трубопроводом одного пульсатора, эжектор разгрузочного устройства размешен в верхней части корпуса, причем его сопло соединено с нагнетательным, трубопроводом другого пульсатора, всасывающий трубопровод которого подсоединен к корпусу , нижн часть корпуса снабжена трубопроводом, соединенным с загрузочной трубой, укрепленной в отверстии дренажной решетки.one pulsator piping; an unloading ejector device is placed in the upper part of the body; its nozzle is connected to the discharge pipe of another pulsator, the suction pipe of which is connected to the body; the lower part of the body is provided with a pipe connected to the loading grate.

На чертеже изображен противоточныйThe figure shows a countercurrent

ионообменный аппарат, продольный .ion exchange apparatus, longitudinal.

Аппарат выполнен из вертикальной колонны 1, загрузочной трубы .2 с воронкой .дл приема ионита, расположенной выше уровн растворав колонне, инжектора 3, эжектора 4, осушающего устройства 5 и пульсаторов 6 с распределительными клапанами 7 и 8.The apparatus is made of a vertical column 1, a loading tube .2 with a funnel for receiving an ion exchanger located above the level of the dissolving column, an injector 3, an ejector 4, a drying device 5 and a pulsator 6 with control valves 7 and 8.

Claims

The column in the upper part has a pipe 9 for the supply of fresh solution, and in the lower part, a drainage grate 1O with a hole and a pipe 11 located under it 6 to lead out of the treated solution pipe, Pipeline 12 of the injector 3 output cells to the center of the spleen grid 10. The loading pipe 2 is connected to the suction chamber of the injector. In order to maintain the level of the solution in the loading tube and to facilitate the operation of the injector, the loading tube is connected by pipe 13 to the sub-grid RT-frame 14 of the column. To supply the solution to the injector from the pulsator in one direction, the pulsator is connected by pipe 15 to the sublattice cavity 14 of the column and has valves 7 and 8. The end of the suction pipe of the ejector 4 is set at the position of the ion exchanger in the column. An ocyluaKaiee device 5 is fastened to its pipe 16 at the required height above the column, nap {3 is an inclined sieve, the fluid collection of which is connected to the upper cavity of the colony through pipe 17 to return the solution pumped out with the ion exchanger. For supplying the solution in one direction to the jet pump, its pulsator has valves 7 and 8 and is connected by pipe 18 to the upper cavity of the column filled with the solution flowing into it. When the apparatus is in operation, the solution entering through the nozzle 9 fe the upper part of the column passes through the ion exchanger layer and the drainage grate 10 into the lower cavity 14 and further through the nozzle 11 is withdrawn from the column. Towards the flow of the solution in pulses from the bottom up, the neonite layer doesn’t move in nepo the same operation of the injector 3 and the ejector 4. Fresh ionite through loading pipe 2 is fed to injector 3 and pumped into the column with a stream of solution from a pulsator. Ionite passing through the column as the level of noc-fynvLKiawMl into the column is pumped out with an ejector 4 into a drying device 5, from which dry ionite is transferred to the drying system with an ejector 4 into a drying device 5, from which dry ionite is transferred. the subsequent sorption stage, and the solution separated from it is returned via pipeline 17 to the column. In connection with looping of the streams of the solution passing through the jet pulses, the solution flow rate through them does not affect the flow rate of the solution passing through the column. Therefore, it is possible to work with the apparatus at elevated liquidation flow rates through jet pumps, which facilitates the transportation of ion exchanger through them. Claim 1. A counter-current ion-exchange apparatus comprising a vertical body, a bottom drainage grate with a hole, a loading device with a loading tube and a discharge device with an ejector and two pulsators with suction and discharge pipes, characterized in that efficiency / flow in the column process by reducing the wear of the ion exchanger, the loading device is in the form of an injector, the discharge pipe of which is connected to the drainage grid opening, and the nozzle is from oppressive piping single pulsator. .

2. The apparatus according to claim 1, of which is that the ejector of the discharge device is located in the upper part of the body, and its nozzle is connected to the discharge pipe of another pulsator, the suction pipe of which is connected to the body,

3. The apparatus according to the preceding paragraph, 1, of that, and with the fact that, for the purpose of additional flooding of the charged ion exchanger, the lower part of the body is equipped with a pipeline connected to the loading tube, fastened in. drainage grid opening.
