Reducing IC (Internal Circulation) anaerobic reactor

Abstract

The invention discloses a reducing IC (Internal Circulation) anaerobic reactor which comprises a tank body, wherein a housing of the tank body comprises an upper section, a middle section and a lower section from top to bottom, a gas-liquid separator and an upper reaction chamber are arranged inside the upper section, a three-phase separator and a gas collector are arranged inside the upper reaction chamber, a lower reaction chamber is arranged inside the lower section, a water distributor is arranged inside the lower reaction chamber, the upper section and the lower section are cylindrical, the upper end and the lower end of the middle section are respectively connected with the lowest end of the upper section and the uppermost end of the lower section, and the diameter of the middle section is gradually reduced from bottom to top, so that the diameter of the upper reaction chamber is less than that of the lower reaction chamber. According to the reducing IC anaerobic reactor, by adopting a reducing design with large lower part and small upper part, the diameter of the upper reaction chamber is reduced, no influence is caused to normal internal circulation, but an internal circulation device is simply manufactured, thus manufacturing materials are saved, and the reducing IC anaerobic reactor is easily constructed. The reducing IC anaerobic reactor is simple and easy to operate, and high in volumetric loading, and is suitable for anaerobic treatment on high-concentration organic wastewater.

Description

technical field [0001] The invention relates to equipment for anaerobic treatment of organic wastewater, in particular to an IC anaerobic reactor. Background technique [0002] IC (Internal Circulation) anaerobic reactor, also known as internal circulation anaerobic reactor, is a highly efficient anaerobic reactor. It comprises a tank body, the shell of which is straight and cylindrical, and the inside of the tank shell is divided into an upper reaction chamber and a lower reaction chamber. There is a gas-liquid separator on the top of the upper reaction chamber, and a three-phase separator, a gas collector and a riser are arranged inside the upper reaction chamber. There is a water distributor at the bottom of the lower reaction chamber. There is also a return pipe running through the upper and lower reaction chambers of the IC anaerobic reactor in the tank. The upper end of the return pipe is connected with the gas-liquid separator, and the lower end is connected with th...

Problems solved by technology

However, the distributor is installed outside the reactor. In order to achieve uniform distribution of nozzles on the water outlet circumference, the water distribution branch pipes have different directions, the accessories are not uniform, the installation requirements are high, the engineering workload is large, and the liquid flowing back from the return pipe is not fully returned. Fully utilized, the water intake and internal circulation have not yet achieved complete integration
