Description
Technical Field
The invention relates to the field of biotechnology research, in particular to a bioreactor device.
Background
The technical complexity of preparing, reprocessing and disposing of large quantities of organic waste, including livestock and poultry manure, generated during the productive activities of agricultural and livestock enterprises, requires improvements in the equipment available for the efficient disposal of organic waste.
To enhance the mass exchange process between anaerobic microorganisms and biomass, a series of conditions must be met: of which the most important is to increase the number of microorganisms in the bioreactor volume and to enhance efficient mixing of the biomass, thereby optimizing the ability of the microorganisms to contact the biomass particles and maintaining a temperature that stabilizes the biomass.
The way in which the number of microorganisms increases is described in the famous patents RU2377191, IPC C02F 3/00 (convention priority: 10/29/2003 DE 10350502.4) published on 12.27.2009: by immobilizing the microorganisms in an immobilization layer, which is located in the middle of the bioreactor, is made in the form of parallel carrier elements. The carrier elements are plate-shaped and arranged in parallel, so that flow paths are created in the vertical direction between such elements.
The carrier element is porous, the pores being interconnected by the polymer and the expanded clay particles. The plates are spaced from each other by a distance of 3-6cm, with a particularly preferred distance of 3.5-5.5 cm. Arrangement of the carrying elements: the reactor is intended to be situated in a cross-section of the reactor, viewed from above, and is surrounded by hexagonal blocks, but it can also be placed in other positions, such as rectangular blocks, blocks of a substantially polygonal shape or curved plates. While on the carrier element, the reactor may be contaminated with microorganisms.
According to patent RU2377191, the proportion of the support elements to the microorganisms in the bioreactor amounts to 15-40%, which greatly reduces its performance.
For information on the efficiency of fermentation of biomass in bioreactors, which can be used in devices for mechanical agitation of biomass, reference may be made to EN2664457C1, IPC C02F11/04, C12M1/02, C12M1/107 and C12M1/38, published in 8, 17, 2018, and EN2651940C1, C12M1/02, C12M1/107, C12M1/36 and C02F11/04, published in 24, 4, 2018. However, mechanical mixing cannot be used with bioreactors with immobilized microbial carriers.
At the same time, devices for regulating the temperature of the biomass have also been made available. Therefore, in the bioreactor invented according to the published utility model patents RU 118963U 1 and IPC 12M1/00, the means for heating biomass includes a heat exchanger made in the form of a pipe inside the main body of the reactor, reducing the effective use volume of the bioreactor.
The currently known bio-reactor, which is part of a bio-gas plant made according to patents RU 2595426, IPC 12M1/107, C12M1/36, C02F11/04 published on 8/27 of 2016, was used as a prototype, including bearing elements filled with microorganisms and creating vertical pipes for biomass, etc. The bearing member is made in the form of a cylindrical frame coaxially arranged, on the outer surface and/or inner surface of which a material layer having a porous structure is installed to maintain the activity of anaerobic microorganisms, while the distance between the plurality of cylindrical frames is spaced 3-6cm using a spacer bar device. The biomass is brought to a predetermined temperature by a heating operation and a bioreactor having an adiabatic function is used to ensure temperature operation accuracy in the reactor, stability of a set biomass temperature cannot be ensured, and processing quality of raw materials is affected. In addition, the design of the coaxially arranged support elements in the form of cylindrical frames does not provide high quality biomass mixing.
Disclosure of Invention

Meanwhile, the functionality of the device is continuously enhanced, so that guidance is provided for constructing biogas plants with different productivity.

Further, each biomass distribution unit comprises a distribution chamber connected to an inlet branch pipe, each distribution chamber being connected to at least 2 nozzles, which are provided with cleaners.
Further, temperature sensors are arranged inside each bioreactor and inside the heating circuit, and the temperature of the biomass inside each bioreactor is adjusted by automatically adjusting the temperature of water entering the heating circuit.
Further, the bioreactor was equipped with 2 outlet pipes.
Increasing the productivity and quality of biomass processing can be achieved by: increasing the number of microorganisms, improving the mixing force of the biomass in the bioreactor organism and stabilizing the temperature state of the biomass in the volume of the bioreactor apparatus. It is possible that the extended functionality of the bioreactor assembly is accomplished by using a corresponding amount of consistency with the design installation and reactor productivity.
Referring to fig. 1, a bioreactor apparatus 1 consists of a set of identical types of side-by-side operating bioreactors 2. The size of the production rate set by the bioreactor system 1 determines the number of bioreactors. The main body of each bioreactor 2 is in the shape of a vertical cuboid and is equipped with a water heating function, made in the form of a heating circuit 3. The coolant circulates in the heating circuit through a nozzle I4 with a supply function and a nozzle II5 with a function of removing heated water.
Referring to fig. 6, there is an illustration of the side wall of a bioreactor having two parallel line circuits.
The number of heating circuits and the distance between adjacent circuit elements are selected according to the conditions for uniform heating of the surface of the housing wall. In this case, the width of the bioreactor depends on the conditions for rapid heating of the biomass across the width of the bioreactor, with an optimal range of 600 to 800 mm. The heating circuit 3 is equipped with thermal insulation means located in the top 6 and left side wall 7 of the bioreactor housing. The right side wall 8 is not provided with a heating circuit. The bioreactor body 2 is mounted as before on the left side wall 7, provided with a heating circuit, and the right side wall 8 is not provided with other heating circuits. The side wall of the bioreactor without the heating circuit at one end was closed by panel I9 equipped with a heating circuit, and the side wall of the bioreactor without the heating circuit at the other end was closed by panel II10 of the heating circuit. The bioreactor is connected to the bioreactor 2 via a flange 11 with a panel I and a panel II. This heating design simplifies the installation procedure of the bioreactors in a unified apparatus, while the assembly allows for overall heating of each bioreactor.
Referring to fig. 2, each bioreactor 2 is provided with a cover 12 on which is mounted an inlet tube 13 connected to a distribution unit 14, closed by a housing 15, and an outlet tube 16. To ensure uniformity of the discharge rate, the bioreactor can be equipped with nozzle III17 and nozzle IV 18.
Referring to fig. 7 and 8, the distribution node is designed for uniform distribution of biomass over the surface of the biofilter and comprises distribution chambers 19 connected to inlet pipes, each connected to at least two nozzles vi 20 and equipped with a cleaner 21.
Referring to fig. 4, the main body inside each bioreactor 2 is divided into a plurality of modules by vertical longitudinal 22 and transverse stiffeners 23, and the elements of the biofilter 24 are installed in the form of bio-adder modules 25.
Each B3 module contains modules 26 for microbial colonization, the modules being arranged in layers. Each module consists of a vertically oriented tubular element and is secured along a longitudinal end face. The cross-sectional shape of the elements may be different, for example square or oval. The relative positions of the modules provide for displacement of elements of the modules located in adjacent layers in the horizontal plane.
The elements of the module are made of a polymeric material, have a thickness of 5-10 mm, have a porous structure, the pores of which are suitable for the sedimentation of microorganisms. Microbial settling on the module surface can act on the increase in microbial numbers, thereby accelerating the anaerobic treatment process of the biomass.
The prepared biomass is fed into each autonomous operating bioreactor 2 from above, the biomass being distributed evenly over the entire surface above bioreactor module B3 with the aid of distribution unit 14. In each B3 module, biomass moved through the conduit formed by the first layer module and into the second layer module through the gap between the first layer module and the second layer module elements. In this case, a passive mixing of the biomass takes place in the gaps between the modules, and a partial flow of the biomass split and the displacement of the elements forming the second layer takes place through the ducts formed by the module elements of the first layer. Subsequent mixing of the biomass proceeds in a similar manner in the bottom module. Therefore, the larger the number of module layers, the better the mixing effect.
Temperature control of the bioreactor is accomplished by the supply of biomass and temperature regulation of each biomass within the bioreactor, with automatic regulation of water temperature by temperature sensors I27 and II28 installed in the heating circuit and inside the bioreactor.
The productivity of the biomass process and its quality are improved and improved by increasing the number of microorganisms in the biofilter 24 and improving the mixing force of the biomass in the bioreactor 2 and maintaining a constant biomass temperature.
The internal measurement data of the bioreactor 2 are: a length of 2.5 meters, a width of 0.7 meters, a height of 3.6 meters to 6 meters, and a volume of 6.3 cubic meters to 10.5 cubic meters per bioreactor 2.
