The stabilizing ring is used with the agitator at the same time, so that the mixing shaft can play the role of radial centralization in the working process. This series of stable ring structure is divided into integral wh and split WF. It is suitable for open turbine, disc turbine and propeller agitators. Our company can design for different industries and working conditions, and provide various specifications and materials of stability ring
With the improvement of biochemical technology and the increasing demand of biochemical products, higher and higher requirements are put forward for the large-scale, energy-saving and efficient fermentation tank. The energy consumption of stirrer in fermentation tank accounts for more than half of the whole production line, so it is very important to select the appropriate agitator (size and type combination) for large fermentation tank. The scale-up of agitator is a complex problem related to the technological process. Previously, it can only be scaled up step by step through experience. According to the amplification criteria obtained, it can be extrapolated to industrial scale. With the continuous development of computational fluid dynamics (CFD) technology and high-performance computer, the use of CFD technology to design large-scale fermentation tank has become the main trend.
The jet swirl gas distributor is mainly composed of Venturi nozzle and spray ring. The structure model and flow model are shown in the following figure: when the compressed air with the pressure of PP injected into the fermentation tank is ejected from the contraction nozzle, the static pressure energy is converted into the velocity energy, and the pressure at the suction port of the ejector is reduced to P1. Under the effect of the compressed air injection, the fermentation broth VL with the density of R1 is inhaled and enters the diffuser of the ejector together with the air, The gas-liquid two-phase mixing developed from initial mixing to intense mixing oscillation, and produced gas dynamic foaming and pressure foaming, which made fermentation broth and air be crushed into a large number of micro particles, creating a highly turbulent, expanding and constantly updated surface emulsion interface between gas and liquid.
Th-2005a biochemical process control system developed by Tianhui company is composed of single chip microcomputer and liquid crystal display screen as the core, and uses 5.7-10.4 inch high standard liquid crystal screen as man-machine interface. The parameters that can be detected and controlled are temperature, pH, dissolved oxygen, rotational speed, foam, liquid level, tank pressure, air flow rate, redox potential, tail gas O2 and CO2.
