Uniform-water-distribution rotational-flow anaerobic water distributor and anaerobic generator

Abstract

The invention relates to the technical field of sewage treating, in particularly to a uniform-water-distribution rotational-flow anaerobic water distributor and anaerobic generator. The anaerobic water distributor comprises a water distributor body and a water inlet branch pipe, the water distributor body is provided with a flow dividing module and a rectifying module in a circumferential array mode, the water inlet branch pipe is communicated with the flow dividing module, and the rectifying module is arranged on the outer side of the flow dividing module; the flow dividing module is providedwith a single-layer flow channel, and a plurality of flow dividing guide plates are spirally arranged in the single-layer flow channel; the rectifying module comprises a double-layer water distribution plate, a first-layer rectifying flow channel and a second-layer rectifying flow channel are arranged on the two sides of the double-layer water distribution plate respectively, and a plurality of inclined rectifying flow guide plates are spirally arranged in the first-layer rectifying flow channel and the second-layer rectifying flow channel. The anaerobic water distributor has the beneficial effects that the flow dividing module and the rectifying module are adopted, primary mixing of fluid flowing out of the water inlet branch pipe and secondary full mixing of the rectifying module and biogas with water are achieved, and the uniformity of anaerobic water distribution is achieved.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a uniform water distribution, swirl anaerobic water distributor and anaerobic generator. Background technique [0002] Anaerobic reactors are widely used in the biochemical treatment of high-concentration organic wastewater, high-suspended solids, high-biological toxicity wastewater, and intermittent production wastewater from food, fermentation, alcohol, chemical, pharmaceutical, and farming industries. Among them, the water distribution device in the anaerobic reactor is the "heart" of the reactor, which occupies a pivotal position in the sewage treatment process. [0003] In the prior art, the water distribution methods widely used in anaerobic reactors are: faceplate-type point-to-point water distribution and branch-like water distribution; faceplate-type point-to-point water distribution has water distribution points in the process of treating high-concentration org...

Problems solved by technology

[0003] In the prior art, the water distribution methods widely used in anaerobic reactors are: faceplate-type point-to-point water distribution and branch-like water distribution; faceplate-type point-to-point water distribution has water distribution points in the process of treating high-concentration organic wastewater in anaerobic reactors. Easy to clog, and after clogging, the water distribution pipeline is difficult to clean; in the process of dendritic water distribution in the process of treating high-concentration organic wastewater in the anaerobic reactor, there is uneven water distribution, there is a dead zone at the bottom of the reactor, and the sludge and wastewater are mixed Uneven phenomenon, there are also problems that the water distribution pipes are easy to block, difficult to find and clean after blockage

Thus affecting the treatment efficiency of the anaerobic reactor
