Description

The invention relates to the microbiological industry and is intended for the cultivation of microorganisms of predominantly hydrogen bacteria.

The epiyieHTep is known for growing microorganisms, which contains a tank, ejectors, a pump, and a piping system for circulating nutrient media and gases, while the tank is designed as an annular cylinder, and the ejectors are installed on its inner surface at an angle to the tangent less.

The disadvantage of this fermenter is a VL unit, with a low volumetric mass transfer coefficient and, as a result, low specific productivity per unit volume of the apparatus.

The closest in technical essence to the proposed is. a fermenter for growing microorganisms, predominantly hydrogen bacteria, containing a tank made in the form of a torus, ejectors for mixing the culture liquid with gases, a liquid ring collector connected to the nozzles of the ejectors, and a pump for circulating the culture liquid whose discharge pipe is connected to the collector and the suction pipe to the bottom of the torus C21.

However, the specific productivity of the fermenter is small due to the fact that only 8% of its volume falls within the zone of intensive mass transfer.

The purpose of the invention is to increase the lot

Noah performance. I

The goal is achieved in the fermenter mainly for hydrogen bacteria, which contains a tank made in the form of a torus, ejectors for mixing the culture liquid with gases, a liquid ring collector connected to the ejector nozzles, and a pump for circulating the culture liquid whose discharge pipe to the collector, and the suction inlet to the lower part of the torus, the annular collector and ejectors are placed inside the torus, in its upper half, and the mixing chambers of the ejectors are formed the top of the torus's upper half, attached to it at equal distances from each other by curved vertical partitions and attached to the partitions to the bottom by a ring-shaped curved plate, which forms a KOTORA is described by the equation r 0, where r is the radius-vector of the annular curved plate, d - the diameter of the torus cross section is the angle of rotation of the radius vector, the radius of curvature of each partition being 1.0-1.2 diameters of the cross section of the torus, and its length is 1.52, 0 the diameter of the latter.

FIG. 1 shows a fermenter, a transverse vertical section; in fig. 2 - section aa in fig.

The fermenter, mainly for hydrogen bacteria, contains a tank made in the form of a torus 1, ejectors 2 for mixing the culture liquid with gases, a liquid ring collector 3 connected to salts 4 Ejectors 2 and a pump for circulating the culture liquid, the discharge nozzle 5 of which is connected to the collector 3, and the suction inlet 6 to the lower part of the torus 1 The annular collector 3 and the ejectors 2 are placed inside the torus 1 in its upper half.

The mixing chambers of the ejectors 2 are formed by the inner surface of the upper half of the torus 1, attached to it at equal distances from each other by curved vertical partition walls 7, the radius of curvature of which is from 1.0 to 1.2, and the length is from 1.5 up to 2.0 times the diameter of the cross section of torus 1 and attached below to the bulkheads 7 by a curved ring plate AND, which is described by the equation g 0,2bd-,

where r is the radius vector of the formations of the annular curved plate; d is the diameter of the cross section of the torus; and H is the angle of rotation of the radius vector.

The fermenter is also provided with nozzles 9 for supplying gases and a cooling jacket 10 with supply nozzles. 11 and 12 coolant outlet.

The fermenter mainly for hydrogen bacteria works as follows.

A solution of nutrient salts and a suspension of microorganisms, for example hydrogen bacteria, are poured into the tank in the form of torus 1 in the amount of 75-80% of the total volume of the fermenter. The nozzles supply hydrogen gas, oxygen and carbon dioxide in a given ratio and the required quantity, and turn on pump 4. Microorganism suspension under the action of pump 4 from the discharge pipe 5 enters the collector 3 and through nozzles 4 is injected into the mixing chambers of ejectors 2 where vacuum zones are created. The slurry jets inject the gases supplied through the pipes 9 and the gas mixture in the gas volume of the torus 1.
