Embodiment 1

[0059] 1. Cabin

[0060] The production adopts reinforced concrete structure, and the effective volume of the hydrolysis fermentation cabin is 1500m 3 , the effective volume of the methane fermentation cabin is 5000m 3 .

[0061] 2. Stir

[0062] One of the key issues in dry fermentation of mixed materials is agitation. The agitation in this design is pneumatic agitation to collect the gas produced by fermentation (hydrolysis is hydrolysis waste gas, and methane fermentation is the mixed gas of methane fermentation). Since the overall fermentation material filling height of this process design is significantly lower than other dry fermentations, Therefore, it is realized that the stirring gas pressurizing device can adopt the form of a general-purpose fan, which reduces the engineering cost and improves the system stability, and the stirring uniformity is also enhanced.

[0063] 3. Thruster

[0064] This design adopts two-wing transverse propeller design under the conditi...

Abstract

A horizontal large-scale continuous biogas dry fermentation device and method, which belong to the technical field of dry biogas fermentation. The overall layout of the fermentation cabin adopts a U-shaped reentrant plane layout, and a material propeller is used. The material propeller is a double-shaft double-blade opposite The bite rotation mode, the irreversible propulsion of the material can be realized through the relative rotation of the double blades, and the propeller is installed at the bottom of the main partition wall of the fermentation cabin. Due to the elongated design of the double-blade impeller along the direction of the rotation axis, a large amount of material can be propelled, and the propeller can achieve different propulsion capabilities by changing the rotation speed. The occlusal design of the two wings of the propeller can realize the non-returning of the material during the propulsion process. The whole reactor of the present invention presents that the inlet and outlet ports are arranged close to the ground, and the operation is convenient and energy-saving. It realizes uniform discharge and overall push flow material flow, realizes no mixing of materials in the whole reaction process, and makes fermentation more thorough.
