Internal circulation (IC) anaerobic reactor

Abstract

The invention discloses an internal circulation (IC) anaerobic reactor, comprising a tank, a mixing area, a first anaerobic zone, a lower three-phase separator, a second anaerobic zone, an upper three-phase separator, a settling zone and a gas-liquid separator, wherein the gas-liquid separator is respectively connected with the lower three-phase separator and the upper three-phase separator by a rising pipe; the IC anaerobic reactor is characterized in that the mixing area comprises a tapered tank bottom, a water inlet pipe arranged at the upper side of the tapered tank bottom, and a return pipe arranged at the upper end of the water inlet pipe; a tapered pipe orifice is formed in the lower end of the return pipe, and the gas-liquid separator is connected with the upper end of the return pipe; a ring-shaped precipitation tank is arranged at the periphery of the tapered tank bottom, and a plurality of mud discharge pipes are arranged on the side wall of the ring-shaped precipitation tank; a circulating pump is arranged outside the tank, and the two ends of the circulating pump are respectively connected with the return pipe and the settling zone by a circulating pipe. The IC anaerobic reactor has the beneficial effects that inflow water is uniform, settled mud is distributed around the cone bottom, and the mud in equipment is conveniently emptied by means of ring-shaped mud discharge.

Description

technical field [0001] The invention relates to an environmental protection equipment, in particular to an IC anaerobic reactor. Background technique [0002] IC (internal circulation) reactor is a new generation of high-efficiency anaerobic reactor, that is, an internal circulation anaerobic reactor, which is similarly composed of two layers of UASB reactors connected in series. The current IC anaerobic reactor still has the following technical defects: the circulating water of the external circulation directly enters the mixing zone from the bottom of the tank, and the water inflow is uneven; the sludge discharged from the tank cannot be drained. [0003] For this reason, the applicant proposed a new technical scheme on the basis of the prior art, and provided a novel IC anaerobic reactor. Contents of the invention [0004] The object of the present invention is to provide an IC anaerobic reactor. [0005] In order to achieve the above object, the technical solution of...
