STAIC high-efficiency anaerobic reactor

Abstract

The invention discloses an STAIC high-efficiency anaerobic reactor. The STAIC high-efficiency anaerobic reactor is characterized in that the heights and diameters of two superposed reaction chambers are different from the height and the diameter of a TAIC anaerobic reactor, the diameter ratio of an upper tank to a lower tank is 5:4, the height ratio of the upper tank to the lower tank is 1:4, the height of the whole reactor ranges from 12 to 30 meters, and the high-diameter ratio of the whole reactor is 3 to 6; an adjustable speed circulating pump is arranged on a sludge return pipe; an automatic traction backflow circulator is arranged on a feed pipe; a protective cover is arranged at a feed pipe orifice; a biogas slurry and biogas residue overflow pipe is higher than the return pipe; a back washing switch is arranged on the feed pipe. The STAIC high-efficiency anaerobic reactor has the advantages that the volumetric gas production rate is high, the fermentation rate of the STAIC high-efficiency anaerobic reactor can be twice of that of the TAIC reactor, the area occupied by the STAIC high-efficiency anaerobic reactor is less than that occupied by the TAIC reactor, the capital investment is substantially reduced, the adaptability is widened, as a feed liquid in a backflow tank can be automatically dragged, the blockage of the feed liquid in the pipeline is effectively avoided, the service efficiency is improved, and more importantly, the anti-rush-out load of the tanks is increased.

Description

technical field [0001] The invention relates to an anaerobic reactor, in particular to a STAIC high-efficiency anaerobic reactor. Background technique [0002] At present, the anaerobic reactor with a high anaerobic reaction rate is the TAIC anaerobic reactor (Note: TAIC anaerobic reactor is one of the inventors), this reactor superimposes two UASB reactors to form a horizontal The tower shape is large and small on the cutting surface, and its interior accommodates the fermentation feed liquid for anaerobic reaction fermentation. The interior of the two UASB superpositions is equipped with an upward return pipe, a three-phase separator, and a distribution pipe. The upper part is also equipped with a gas-liquid separator. , active circulation pump, in this case, compared with IC, TAIC anaerobic reactor effectively improves the organic loading rate of feed, making it easy to realize the internal dynamic circulation of feed liquid, and enhances the anti-shock of anaerobic react...

AI Technical Summary

Problems solved by technology

[0003] However, in the application of the TAIC anaerobic reactor for many years, we have discovered new problems: (1) It is not suitable for the initial internal circulation start-up of the feed liquid containing high suspended solids

(2) It is not easy for the feed liquid to flow automatically or naturally in the container for operation adjustment

(3) The starting and running time of the anaerobic reactor cannot be accurately controlled, resulting in a longer starting time

(4) The outlet water level of the anaerobic reactor is high, and the internal pressure of the container increases, which requires the tank body to increase the compression coefficient, resulting in an increase in the construction cost of the anaerobic reactor
