Pretreatment unit with front-loading homogenization tank and process thereof

Abstract

The invention discloses a pretreatment unit with front-loading homogenization tanks, which belongs to the technical field of feeding pretreatment of a biogas station. The pretreatment unit comprises the first homogenization tank, the second homogenization tank, channel steel, a mechanical grille, dosing holes, an dosing channel and a feeding ditch, wherein the first homogenization tank and the second homogenization tank are portions for collecting pretreated fecal sewage and correspond to a first feeding hole and a second feeding hole respectively, the fecal sewage enters the homogenization tanks through the feeding holes, the two feeding holes are connected to the tail end of the feeding ditch to receive the fecal sewage coming from the feeding ditch and filtered through the mechanical grille to remove fecal, the mechanical grille is located at the front end of the feeding ditch, the dosing channel and the plurality of dosing holes are formed at the front of the mechanical grille, andthe dosing holes are formed above the dosing channel. At the same time, the invention also provides a pretreatment process with the front-loading homogenization tanks using the pretreatment unit withthe front-loading homogenization tanks to realize the pretreatment of fecal sewage.

Description

technical field [0001] The invention relates to the technical field of feed pretreatment of a biogas station, in particular to a pretreatment unit and a process for a homogenization tank. Background technique [0002] Traditional biogas stations mostly use open feed hoppers to feed manure. When sewage suction trucks add manure to the feed hopper, shortcomings such as liquid splashing and odor diffusion are exposed, and open feed hoppers are easy to Breeding of mosquitoes and flies seriously damages the surrounding environment of the feed hopper. [0003] Furthermore, open feed hoppers often use screens or steel mesh to filter residues. This method of filtering residues is poor, and a large amount of solid matter still enters the homogenizer tank, which causes great damage to the feed submersible sewage pump. The net or steel mesh is inconvenient to clean, and it is easy to cause blockage. [0004] Therefore, the present invention provides a reliable and high-efficiency clo...
