 The microscope cultivator p r anisma contains a body 1, divided by the height of the overflow plates 2 | on section 3, communicated with the aid of k | analogs 4, and having in each section reinforced under iridescent plates - f, K 2; diffuse partitions 5 with the formation of gas cavities 6 between them, and an external circulation circuit consisting of a pump 7 and heat exchanger 8, connected with pipelines 9 and 10 to the upper and lower t of the hull. The transfer plates i have perforated sections 11. Each gas cavity 6 of section 3 is connected through a single section with gas Iolost by means of a gas duct 12 with 1) sectioning the height of the housing section: The channels for the circulation of sour, hydrogen-containing and natural gases. The housing 1 of the apparatus is equipped with nozzles 13 and 14 for. separate supply of natural and oxygen-containing gases, fixed in the lower part, and nozzles 15 and 16 for separate removal of these gases, fixed in the upper part of the body. Nozzles 13 and 15 for supplying and discharging natural gas are connected by means of an inducer 17 of its flow. The combustion gas is discharged through pipe 18,

Pipe 19 is used to supply process water and mineral nutrition, and pipe 20 is used to drain the product.

The device works as follows

The culture fluid is taken by pump 7 from the lower part of housing 1 and is pumped through heat exchanger 8 to thermostat it into the upper part of housing 1, from where it then flows. from the top to the bottom of the plates 2. At the same time, oxygen-containing gas is introduced separately through the nozzle 14, and through nozzle 13 - natural gas (methane).,

The oxygen-containing gas and methane separately move upwards without mixing. Methane from the gas cavity 0 6 aerates the medium located on the overflow plate 2, and collects in the gas space of each section 3 under a continuous upstream partition 5. Then methane through gas 5 water 12, mine upstream section 3 enters the next course of methane the gas cavity 6 and the passage through the corresponding sections 3 are discharged through the pipe 15, while the methane can be returned to the disposal after the gas consumption booster 17 when a fresh portion of methane is added to its volume,

35 Oxygenated gas, similarly to methane, also passes upwards through sections and is removed from nozzle 16 for purification or to the atmosphere.

In case of separate alternate a: elution of the culture liquid with oxygen and methane when it moves from top to bottom, the formation of gas

cavities that contain a mixture of these gases in their 3: 1 critical ratio, at which explosive conditions arise.

The aimaipaTa design allows the culture fluid to saturate in a low layer on overflow plates with methane and oxygen, which increases the driving force of mass transfer along the specified gases.

The driving force of the mass transfer is determined by the fact that methane and oxygen dissolve in the culture medium alternately as the fluid flows from the section to the section, i.e. they do not interact with the mass transfer process during joint dissolution.

Thus, the formation of a gas cavity under each overflow plate and their alternate communication with each other through the section for separate aeration of the medium when the methane-oxygen moves upward through the sections countercurrent with respect to the culture fluid, prevents the occurrence of highly hazardous conditions during the process and increases the specific productivity apparatus by 10-15%.
