SU954419A1 - Apparatus for hydrolysis biomass of microorganism - Google Patents

Description

The invention relates to the microbiological industry and can be used to hydrolyze the condensed biomass of microorganisms to produce amino acids or a paste of blue-green algae with a solids content of 5-10%.

The closest to the present invention is an apparatus for hydrolysis, which is a cyclical container with a tubular heat exchanger placed in it, above which is installed a device for intensive mixing of the paste with its transformation into a hydrolyzate. The paste, heated in a tubular heat exchanger, is vigorously stirred in a perforated disc mixer l.

Such instrumentation requires the availability of thermal power steam installation.

The aim of the invention is to simplify (1 the design and the intensification of the process of hydrolysis.

The goal is achieved by the fact that the heater is made in the form of immersion burners, in the lower part of which circulating cylinders with toro-shaped perforations are installed.

private collectors for the supply of condensed biomass.

The drawing shows schematically the apparatus.

The device consists of a heater 1 with a conical bottom, on the lid 2 of which the heads of the immersion burners 3 are fixed. The lower edge of the burners 3 is inserted into the cylinders 4,

10 bottom edge of which is equipped with a mountain-like collectors 5, on the inside. The diameter of which has holes 6. The conic part of heater 1 is separated by a calming lattice 7 with grate diamonds. Under the grate 7 there is a cap with a pipe 8, which is drained of water. A device 9 is installed at the bottom of the conical bottom for unloading non-hydrolyzing particles (sand). Therefore, between the heater 1 and the mixer 10 in the lower part is made in the form of a threshold 11. A pipe 12 is installed on the top cover 2 of the heater 1 for exhausting steam G. At some distance from the liquid level in the heater, in the concentration zone of the condensed mass, a pipe 13 with openings is installed,

30 are directed to threshold 11. In a mixture of tol 10, a submersible is mounted on a krlik on 1 latch 14 with a circulation cylinder. The surface of the liquid is fitted with sprinklers — 15 acids connected to the metering pump 16. An exhaust pipe is connected to the opening of the mixer lid, which is connected to the pipe. 12, in which a heat exchanger 17 connected to the pump, dispenser 18 and collector 5 is mounted. The bottom of the mixer 10 is communicated to the control device 19 and equipped with a mixing device 20. The drainage system 2 works as follows . From the metering pump 18, the condensed biomass is pumped through the heat exchanger 17 and partially heated, while the preheater is a condenser for liquefying acid vapors and returning them to the mixture: body 10. Heated mass, a-flows through the openings 6 of collectors 5 into the interior of cylinders 4. At the exit of the flame from the burners 3, in places of intensive convective and radiative heat generation, the mass is partially preheated and comes in contact with a higher temperature. A sharp local heating occurs, as a result of which increases significantly, and the biomass floats up. To create a quiet zone in heater 1 to provide alga sedimentation and sedimentation of non-hydrolyzable heavy particles (sand) below the immersion burners 3, a lattice 7 is installed. Device 9. The foam mass is transported through threshold 11 into mixer 10 with - SUPPORTING high-speed air flow from the openings of pipe 13. Acid is fed to the mass entering the mixer 10 and the sprinkler 15. A submerged burner 14 is installed in the mixer 10 to circulate 7 to preheat the whole mass. Through communication, the mass is heated and mixed with the acid and transferred to aging 19, where, with continuous vigorous stirring, the process of hydrolysis ends. The use of immersion burners allows to intensify the hydrolysis process and reject the heat and power steam installation. Claims 1. Apparatus for. hydrolysis of the condensed biomass of microorganisms by heating in the presence of acid, containing a heater with a horse bottom and a mixer, which is designed to immerse the heater, in order to simplify the design and intensify the process, In the lower part of which, circulating cylinders with toroidal perforated collectors are installed to supply condensed biomass. 2. The device according to n.l, from the l and c o and y so that the conic part of the heater is separated by a grate with grate diamonds.
