Vertical suspended semi submersible vertical turbine pump for bundle tube axial flow biological oxidation reactor

The vertical suspended semi submersible vertical turbine pump is used in the bundle tube axial flow biological oxidation reactor. It consists of an upper head, a feeding device, an intermediate body, a bundle tube, a vertical suspended semi submersible vertical turbine pump, a lower cone, and a microporous aeration device. The upper head, intermediate body, and lower cone are connected by flanges; The feeding device is fixed on the upper head and connected to the upper end of the bundle tube; The power part of the vertical suspended semi submersible vertical turbine pump is fixed at the center of the upper head, and the pump body is fixed at the center of the intermediate body; The bundle tube is uniformly arranged within the circumference of the intermediate as a biological oxidation reaction zone; The microporous aeration device is installed on the lower cone and connected to the lower part of the bundle tube. The circulating mixing of the vertical suspended semi submersible vertical turbine pump eliminates the phenomenon of shaft breakage caused by excessive torque on the large blades; The shell heat transfer structure provides a more stable heat transfer environment for microbial oxidation, and the heat transfer effect is more significant; The enclosed design avoids environmental pollution caused by open mixing tanks; Micro porous aeration and circulating agitation for convective oxidation have improved gas utilization efficiency; This technology is more efficient, energy-saving, safe and environmentally friendly than the vertical stirred tank biological oxidation reactor.
