High-efficiency internal circulation anaerobic bioreactor

Abstract

The invention discloses a high-efficiency internal circulation anaerobic bioreactor. The anaerobic bioreactor comprises a tank body. The tank body is equipped with a gas-liquid separator, an upper layer three-phase separator and a lower layer three-phase separator. The heights of the upper layer three-phase separator and the lower layer three-phase separator can be changed in the tank body. The upper layer three-phase separator and the gas-liquid separator are connected through a telescoping gas collection pipe. The lower layer three-phase separator and the gas-liquid separator are connected through a telescoping riser pipe. The upper layer three-phase separator and the lower layer three-phase separator are equipped with an upper layer gas collection hood and a lower layer gas collection hood respectively. The upper layer gas collection hood is composed of a plurality of upper layer gas collection units through laying. The lower layer gas collection hood is composed of a plurality of lower layer gas collection units through laying. The upper layer gas collection units and the lower layer gas collection units have a structure with an openmouthed lower end and composed of two inclined side plates. The upper part gradient of the inclined side plate is more than the lower part gradient. The internal circulation anaerobic bioreactor can raise the single-layer three-phase separator gas collection efficiency, the internal circulation speed can be adjusted to meet condition requirements of different water inlet speeds and the like, and operation is stable.

Description

technical field [0001] The invention relates to an anaerobic reactor, in particular to a high-efficiency internal circulation anaerobic bioreactor. Background technique [0002] The general structure of the anaerobic reactor includes a straight cylindrical tank, a gas-liquid separator and an upper three-phase separator are installed on the top of the tank, and a lower three-phase separator and a water distributor are arranged in turn. The bottom of the gas-liquid separator communicates with the water distributor through the return pipe, the lower three-phase separator communicates with the middle of the gas-liquid separator through the riser pipe, and the upper three-phase separator communicates with the upper part of the gas-liquid separator through the gas collecting pipe. The internal circulation of the bioreactor constructed by the riser tube and the return tube improves the separation of the internal gas-liquid-solid three-phase mixture for multiple cycles, and makes th...
