Anaerobic reactor and swirl water distributor with integrated water feeding and internal circulation of anaerobic reactor

Abstract

The invention discloses a swirl water distributor with integrated water feeding and internal circulation. The swirl water distributor comprises a water distribution umbrella and an inlet water distributor which is positioned in the water distribution umbrella and on the central axis of the water distribution umbrella, wherein the inlet water distributor is provided with a water inlet and a back flow receiving pipe with an upward opening, a plurality of water distribution branch pipes with water distribution nozzles at tail ends and positioned in the water distribution umbrella are extended at the periphery of the inlet water distributor at the same time, and the water distribution nozzles are positioned on the water outlet circumference. The invention also discloses an anaerobic reactor provided with the swirl water distributor. The anaerobic reactor provided with the swirl water distributor can fully and uniformly distribute water and enable wastewater to fully contact with sludge, so that the mass transfer rate and volume load are improved, and water is uniformly distributed; moreover, the water distributor is simple in structure and simple and convenient in mounting, backflow liquid can reduce the water head pressure loss of the inlet water distributor, and the working efficiency is greatly improved compared with that of the swirl water distributor in the past. The swirl water distributor and the anaerobic reactor disclosed by the invention are widely used in wastewater treatment environmental protection engineering.

Description

technical field [0001] The invention relates to waste water treatment equipment, in particular to an anaerobic reactor and a cyclone water distributor used therein. Background technique [0002] The anaerobic reactor includes a reactor shell, several three-phase separators layered in the reactor shell, a gas-liquid separator at the top outside the reactor shell, and a cloth at the bottom of the reactor shell. The water tank, the three-phase separator and the gas-liquid separator are connected through an air-lift pipe, and the gas-liquid separator is provided with a return pipe leading downward to the bottom of the reactor shell. During operation, the lower part of the reactor shell is filled with sludge, and the external waste water inlet pipe is connected to the water distributor to realize water distribution, agitate the sludge and mix with it, organic matter and sludge contact and mass transfer, generate biogas, gas, Digestive liquid and particles rise to the three-phase...

AI Technical Summary

Problems solved by technology

However, this kind of equipment also has disadvantages, that is, the water inlet distributor is set outside the reactor, the direction of the water distribution branch pipes is different, the accessories are not uniform, the installation requirements are high, the amount of work is large, and the liquid flowing back from the return pipe is not fully discharged. Fully utilized, water intake and internal circulation have not yet been integrated
