New energy biogas digester desulfurization purification and pressure stabilization system

Abstract

The invention relates to a new energy biogas digester desulfurization purification and pressure stabilization system. The new energy biogas digester desulfurization purification and pressure stabilization system comprises a biogas digester, wherein the biogas digester consists of a fermentation chamber, a desulfurization chamber and a power chamber which are arranged along the transverse direction, a gas pipe communicates between the fermentation chamber and the desulfurization chamber, and a desulfurization agent is stuffed in the desulfurization chamber; an exhaust pipe is inserted into thepower chamber, a plurality of two-position three-way valves are arranged on the inner side wall of the power chamber, each two-position three-way valve comprises a shell, valve elements, a normally-open opening P, a reversing outlet A and a reversing outlet B, the reversing outlet A communicates with the desulfurization chamber, and the reversing outlet B communicates with the exhaust pipe; a sleeve being coaxial with a general-way opening P is arranged on each two-position three-way valve, and a piston is in sliding connection to the inner part of each sleeve; a crankshaft is rotatably connected to the power chamber, crank throws corresponding to the pistons one to one are arranged on the crankshaft, and a connecting rod is hinged between the pistons and the crank throws; and a first stirrer is vertically and rotationally connected to the inner part of the fermentation chamber, a second stirrer is vertically and rotationally connected to the inner part of the desulfurization chamber,and the crankshaft drives the first stirrer and the second stirrer to rotate through a transmission mechanism.

Description

technical field [0001] The invention relates to the technical field of new energy, in particular to a new energy methane digester desulfurization purification and pressure stabilization system. Background technique [0002] During the fermentation process of biogas, a large amount of H will be produced 2 S, H 2 S and water vapor work together to accelerate the corrosion of metal pipes and pipe components, and even cause dangers such as blockage, and H 2 Combustion of S produces SO 2 It will not only corrode the metal surface, but also cause air pollution. Therefore, desulfurization and purification treatment is required before the biogas is used; during the use of the closed biogas digester, the pressure in the biogas digester will increase with the generation of biogas. When the pressure in the biogas digester When the temperature is too high, there will be dangers such as explosion, so the biogas digester needs to be treated with constant pressure.
