Description

FIELD OF THE INVENTION The invention relates to the microbiological industry, to apparatus for growing microorganisms.

The purpose of the invention is to increase productivity by increasing the specific rate of oxygen sorption and uniform heat removal throughout the apparatus.

Fig. 1 shows an apparatus for growing microorganisms, a longitudinal section; FIG. 2 is a section A-A in FIG. 1; Fig. 3 shows a nodal assembly 1, 1 in Fig. 4 is the same, without pipelines for supplying a refrigerant; Fig. 5 shows perforations in the plates.

The microorganism growing apparatus contains a vertical tank 1 with nozzles for supplying the nutrient medium 2, withdrawing the finished product 3 and evacuating the gas 4, having an expanded upper part 5, an external circulation loop 6 disposed in the tank 1 along the height of the ascending gas generator - bone flow and aerating device 8. The device 7 for dispersing the ascending gas-liquid flow consists of parallel vertical plates 9 of a wave-like shape, equipped with heat-exchanging jackets 10, o tapering 11 and expanding 12 channels, extending in height; in the tapering 11 sections of the channels, the plates 9 have perforations 13 in the form of scales for transferring fluid into these channels from the expanding 12 sections of adjacent channels, and the aerating device 8 consists of parallel perforated pipes 14 located under the channels 11 and 12. The apparatus also contains a manifold 15 for supplying refrigerant pipes 14. The device works as follows.

The container 1 is filled with a nutrient medium, and a culture of microorganisms is introduced into it, for example, for the production of the hydrin from natural gas. Air and natural gas are separately supplied to the aerating device 8 through pipes 14 and fluid is circulated in the apparatus, which is lowered through the external circulation loop 6, again enters the tank / f and rises through the device 7 to disperse the gas-liquid flow through channels 11 and 12 When lifting medium through channels 11 and 12,

flow turbulization occurs due to a cyclic change in the rate of ascent throughout the entire volume of tank 1 as a result of passing through alternately narrowing 11 and expanding 12 channels. So, when passing through channels 11, the medium moves at a higher speed (as a result, a pressure difference occurs between channels 11 and 12), through perforations 13 from channel 12 there is a flow of medium into channel 11, which mixes and homogenizes in the upstream channel 12 (expanding) from which the medium, in turn, is sucked through the perforator 13 into the next channel 11, homogenized and aerated throughout the entire volume of the container 1 i, the medium rises into the expanded part 5 of the container 1, in which the exhaust gas is removed from the liquid through the pipe 4, and the liquid phase is again lowered along the external circulation loop 6 and enters the lower part of the tank 1.

Heat removal from biomass (thermostatting) occurs continuously in the process of biosynthesis as a result of its lifting and washing the heat exchange shirts 10 located throughout the entire volume of tank 1 and embedded in the plates 9 in their inclined sections through which the cooling water supplied to the collector 15 is passed .

During the rise of the aerated medium and its passage between the undulating plates 9, uniform homogenization is ensured and it is thermostatised throughout the entire volume of tank 1 during the course of biosynthesis.

Wafer-shaped plates 9 can be made of various profiles — rectangular, trapezoidal, sinusoidal, etc., which allows to choose the most effective cross-section of channels 11 and 12, based on the characteristics of the microorganism growing medium, for example. viscosity With a high viscosity environment, it is advisable to use a sinusoidal cross section to reduce resistance, for medium viscosity - trapezoidal, with a viscosity of water it is advisable to use a rectangular cross section, since in this case a sudden change in the cross section of the channels gives a local vortex motion and updating the contact phase.
