Embodiment Construction

[0013] see figure 1 , the invention relates to a gradient circulation stirring method in a biogas reactor, characterized in that it comprises the following steps:

[0014] (1) Circulate the mixed material in the tank from the bottom of the tank to the middle and upper part of the tank;

[0015] (2) The mixed material is transported from the middle and upper part of the tank to the bottom of the tank for reciprocating circulation;

[0016] (3) The produced supernatant is discharged from the upper side of the tank; the biogas is discharged from the top of the tank.

[0017] An anaerobic reactor with a gradient circulation stirring method, including a tank body 8, a biogas pipe 15 and a feed pipe 9, the biogas pipe 15 is installed on the top of the tank body 8, and the feed pipe 9 is installed on the tank The bottom of one side of the tank body 9, the upper part and the bottom in the tank body 8 are respectively provided with a settling area 14 and a diversion cone 7, and t...

Abstract

The invention relates to a gradient cycle stirring method in a biogas reactor and an anaerobic reactor thereof. The anaerobic reactor comprises a tank body, a biogas pipe and a feeding pipe, wherein the biogas pipe is arranged on the top of the tank body; the feeding pipe is arranged at the bottom of the tank body; and the anaerobic reactor is characterized in that a settling zone and a guide cone are respectively arranged on the upper part and the bottom part of the tank body; a downflow weir is arranged at the periphery of the settling zone; the downflow weir is higher than the settling zone and is connected with a liquid discharging mechanism outside the tank body; and the mixed materials in the tank body are turned up and down through a gradient cycle stirring system.

Description

technical field [0001] The invention relates to the technical field of biogas engineering, in particular to a gradient circulation stirring method in a biogas reactor and an anaerobic reactor thereof. Background technique [0002] At present, my country's large-scale biogas engineering technology generally adopts vertical cylindrical anaerobic reactors, and the mixing process generally adopts two methods: effluent reflux stirring and mechanical stirring. Water reflux stirring and mechanical stirring each have their own advantages and disadvantages, which will not be repeated here. Vertical anaerobic reactors that use effluent reflux stirring generally include feed system, discharge system, effluent reflux stirring system, biogas collection system and other parts. The material first enters the bottom of the vertical anaerobic reactor through the feed system, and reacts with the activated sludge in the sludge bed at the bottom of the anaerobic reactor. Under the action o...
