The invention discloses an axial flow biological oxidation reactor with bundling pipes. The axial flow biological oxidation reactor is composed of an upper shell cover, an ore feeding device, an intermediate body, the bundling pipes, a vertical long-shaft pump, a lower conical body and a micropore aeration device, wherein the upper shell cover, the intermediate body and the lower conical body are connected with one another through a flange; the ore feeding device is fixedly arranged on the upper shell cover and is communicated with the upper ends of the bundling pipes; a power part of the vertical long-shaft pump is fixedly arranged at the center of the upper shell cover; a pump body is fixedly arranged at the center of the intermediate body; the bundling pipes are evenly distributed in the circumference of the intermediate body as the biological oxidation reaction area; and the micropore aeration device is arranged on the lower conical body and is communicated with the lower parts of the bundling pipes. The phenomenon of a broken shaft caused by overlarge moment of a large paddle is completely eradicated by circular stirring of the vertical long-shaft pump; a relatively stable heat exchange environment is provided for microbial oxidation of a shell-type heat exchange structure, so that the heat exchange effect is relatively obvious; the environmental pollution caused by an open stirring tank is avoided by the blocked design; the utilization rate of a gas is increased by micropore aeration and circular stirring convective oxidation; compared with a biological oxidation reactor with a vertical stirring tank, the axial flow biological oxidation reactor with the bundling pipes is higher in efficiency, more energy-saving, safer and more environment-friendly.
Description
technical field [0001] The present invention relates to a bundle tube axial flow biological oxidation reactor, in particular to a microbial hydrometallurgical process, which provides a reasonable living and breeding space for microorganisms to oxidize refractory ores, and better realizes the uniformity of gas-liquid-solid three-phase Mixing, providing sufficient oxygen to microorganisms during the oxidation process, and being able to replace a large amount of heat generated during the oxidation process in time to adjust temperature balance, eliminate a large number of bubbles generated by flotation agents, and make the biological oxidation process run smoothly under reasonable conditions conduct. Background technique [0002] Biological oxidation refers to the oxidation of certain minerals such as pyrite and arsenopyrite by means of microorganisms, so that the precious metals (Au, Ag, platinum group metals, etc.) wrapped in them are exposed for the next step of leaching. Th...
