Description

Изобретение относитс к аппаратуре дл перемешивани систем жидкостьгаз-твердое тело, жидкость-твердое тело, рекомендуетс к использованию дл проведени каталитических процессов. Оно может быть применено в химической, нефтехимической, цел .гаозно-бумажной, медицинской и других отрасл х промышленности.The invention relates to apparatus for mixing systems, liquid gas-solid, liquid-solid, it is recommended for use for carrying out catalytic processes. It can be applied in the chemical, petrochemical, whole-paper, medical and other industries.

Известен реакционный аппарат с меиалкой возвратно-поступательного действи , содержащий шток, на котором закреплен диск, перфорированный отверсти ми-соплами с углом конусности предпочтительно ЗО, при этом поперечна площадь отверстий составл ет 0,5% от площади диска flJ.A reciprocating reciprocating reaction apparatus is known, which contains a rod on which a disk is fixed, perforated with nozzle nozzles with a taper angle, preferably AOR, the transverse area of the holes being 0.5% of the flJ disk area.

Применение сопловых отверстий позвол ет интенсифицировать процесс перемешивани . Однако этот аппарат имеет недостаточную интенсивность перемешивани неоднородных сред.The use of nozzle holes allows to intensify the mixing process. However, this apparatus has insufficient mixing intensity of heterogeneous media.

Наиболее близким к изобретению по .технической сущности вл етс устройство дл перемешивани жидкостей и взвесей с газовой средой, которое сйдержит закрытую емкость, ЭИбропривод, соединенный с полым лтоком, иппюишм в верхней части окна,The closest to the invention in its technical essence is a device for mixing liquids and suspensions with a gaseous medium, which holds a closed container, an EI drive, connected to a hollow box, in the upper part of the window,

на котором установлен набор перфорированных дисков и поршень Г2.which has a set of perforated discs and piston G2.

Возвратно-поступательное движение поршн и дисков создает эффективное перемешивание по всему объему емкости, ускор тем самым прохождение различных технологических процессов.The reciprocating movement of the piston and disc creates efficient mixing throughout the volume of the vessel, thereby accelerating the passage of various technological processes.

Однако этот аппарат не может при10 мен тьс -дл проведени и интенсификации процессов с катализатором в замкнутом объеме, так как в нем отсутствует устройство дл загрузки катализатора. Катализатор в известном However, this apparatus cannot be changed for carrying out and intensifying processes with a catalyst in a closed volume, since it lacks a device for loading the catalyst. Catalyst in the famous

15 аппарате может быть помещен только на днище, где интенсивность его омывани незначительна.15, the apparatus can be placed only on the bottom, where the intensity of its washing is negligible.

Цель изобретени - расширение области применени аппарата, интен20 сификаци процесса за счет увеличени кратности циркул ции в емкости.The purpose of the invention is to expand the field of application of the apparatus, intensifying the process by increasing the frequency of circulation in the tank.

Поставленна цель достигаетс тем, что аппарат, вк.пючающий емкость, вибропривод и диски с сопловыми отверсти25 ми, установленные на штоке, снабжен катализаторной коробкой с сопловыми отверсти ми, закрепленной на штоке между дисками.The goal is achieved by the fact that the apparatus, including the capacitance capacitance, the vibro drive and the disks with nozzle holes, mounted on the rod, is equipped with a catalyst box with nozzle holes fixed on the rod between the disks.

Claims

The catalyst box has a truncated cone shape, while the nozzle holes made in its side surface are oriented outwards, and in the base of the box and in the disks - towards the narrowing of the catalyst box. In addition, the ratio of the diameter of the larger base of the catalyst box to the diameter of the disk is i-19H. The apparatus with vibratory mixing is depicted on the charge. It includes a vertical cylinder 1, a vibrodrive 2 mounted on the container lid, pcs 3 with two mixing disks in which nozzle holes 5 are made 5. A catalyst box made in the form of a truncated con with nozzle holes 7 is fixed between rod 4 between the disks 4. the holes are oriented as follows. In the bases of the box and in the disks, they are directed to one side, namely, in the direction of narrowing of the catalyst box, and in its side surface are directed outwards. The diameter of the larger base of the catalyst box exceeds the diameter of the discs 4. This is done to widen the zone of penetration of the pulsation into the catalyst box. The apparatus with vibration mixing works as follows. A solid catalyst is loaded into the box, then liquid reagents are introduced into the apparatus and gas is introduced. Vibrating drive is turned on. Stock with perforated discs and box make reciprocating motion. Due to directional nozzle holes in this way, the medium penetrates through the bottom of the box and comes into contact with the catalyst under pressure from the bottom perforated disc. The upper and lower perforated discs, which vibrate the medium, accelerate the circulation of the medium in the apparatus. Due to the pulsation-circulation movement of the medium in the box zone and inside the apparatus, small-scale pulsations of the medium occur, the surface of phase contact with the solid catalyst increases, the coefficient of turbulent diffusion and circulation ratio in the catalyst zone and capacity increases, which contributes to the intensification of the catalytic process and its reduction duration The economic effect of introducing the invention is to increase the specific productivity of the apparatus by 20-25% by increasing the yield of the product as a result of the intensification of the catalytic process. The estimated economic effect from the introduction of a single apparatus with a volume of 1 m -150 thousand rubles. Claims of invention 1.
