(54) APPARATUS FOR GAS AND FLUID CONTACT

one

The invention relates to apparatus with mixing devices for contact and liquids, which can be used for hydrogenation of fats, for growing microorganisms, for ozonization of water, and in other sealed apparatus of continuous action in the food, microbiological and chemical industries.

A known apparatus for growing microorganisms, comprising a housing, mixing devices made in the form of Segner wheels mounted on an inlet pipe, an aerator located in the lower part of the housing, reflective partitions and; outflow circuit 1.

Closest to the proposed invention in its technical essence and the achieved result is an apparatus for contacting gas and liquid, comprising a vertical housing, an inlet pipe on which a Segner wheel with nozzles is installed, a support ring mounted above the Segner wheel with axial displacement Reflective tshastins, a bubbler, a stirrer and a pump t2 are fixed against the nozzles.

The disadvantages of the known devices are the low intensity of the displacement process due to the inefficient use of the energy of the liquid jets, & also the removal of a significant amount of liquid from the apparatus together with the gas.

The purpose of the invention is the intensification of the displacement process and the subsequent separation of

10 by increasing the contact surface of the phases. /

This is achieved by the fact that the gas contacting device with the liquid is equipped with a turbod mounted on the support ring, with: freely mounted On the supply pipe.

The support ring is additionally equipped with plates, placed on its upper surface, and the Segner wheel -. mounted on the main pipe.

FIG. 1 shows a contact apparatus.

20 pelvis, with fluid, general appearance; in fig. 2 shows section A-A in FIG. one.

The device contains a vertical cylindrical body 1 with a flat lid 2 and the bottom. In the upper part of the housing, on the inlet pipe 3, there is a Segner wheel 4 with nozzles 5 and an injector 6, and above it is an impeller 7, which is mounted on a support ring 8 equipped with reflective plates 9 and 10 fixed to its lower and upper surfaces, by means of rods 11. The impeller on the supply pipe is installed freely.

On Segner wheel 4 fixed shaft 12 with a stirrer 13 located above the bubbler 14.

The support ring 8 with reflective plates is installed with the possibility of axial movement with the aim of changing the scrubber and separation effects.

The apparatus is equipped with a circulation circuit including a pump 15, a heat exchanger 16, pipelines 17 with valves.

The apparatus for contacting gas and liquid works as follows.

When the valve on the gas supply line is opened, bubbling mixing of gas and liquid begins in the lower part of the apparatus. The source fluid and other auxiliary media are fed into the suction line of the pump 15, mixed with recirculation and fed through the heat exchanger 16 to the feed pipe 3. In the injector 6 installed on the feed pipe, a dispersion of the liquid and gas occurs, the jet of which discharges From the nozzles 5, a reactive torque is generated that rotates the Segner wheel 4. The dispersion jets periodically strike elastic baffles 9, which, together with the support ring 8 and the impeller 7, begin to rotate in the opposite direction detecting wheel rotational segner. The impact energy of the dispersion jets is spent on the dispersion of the liquid, converted into elastic energy. plates and partly goes into the kinetic energy of rotation of the reflective plates 9 with the support ring 8 and the impeller 7.

Due to the injection effect of the rotating reflective plates, as well as by injecting the gas, multiple gas circulation in the spray area and spraying is organized. Due to the opposite direction of the Segner wheel 4 and the reflection plates 9 under the ring 8, a zone of active mixing of gas with liquid is created. .

The reflective plates 10 above the ring 8 perform the role of the impeller of the centrifugal fan, creating a significant separation effect in the upper part of the apparatus, which is enhanced by the rotation of the impeller 7. Due to the possibility of changing the gap between the turbine 7 and the ring 8, the latter is vertically moved along the rods 11 , create conditions for controlling the amplitude of oscillation of the plates, as well as the hydraulic resistance of the apparatus pressure in it.

When the Segner wheel 4 and the shaft 12 mounted on it with the stirrer 13 rotate, the bubbling mixing becomes more efficient due to the additional mechanical mixing of the liquid and gas by the stirrer 13. Depending on the solubility of the gas and the need for a particular process, the liquid level in the apparatus can be changed. And then the upper part of the apparatus can be used either under the scrubber {Segner wheel and reflective plates under the ring will work in the gas space), or under a bubbling reactor (the Segner wheel together with the reflective plates under the ring will work under the liquid level, and inject and circulate

in the field of active mixing there will be a gas dispersion in a liquid). The role of separation devices in the latter case is particularly increasing.
