Problems solved by technology

Straw raw materials are one of the most complicated raw materials for bio-natural gas engineering. They have the characteristics of low specific gravity, high impurity content, easy bridging, difficult metering and transportation, and high lignocellulose content. The traditional raw material pretreatment system not only fails to meet the raw material pretreatment system The design requirements and the site environment are very harsh, and the energy consumption is huge

Abstract

The invention discloses a feeding and pretreatment system for raw materials of a methane project. The system comprises a weighing and receiving bin, a smashing machine, a mixing conveyor and multiplepretreatment tanks; the mixing conveyor comprises a motor, a gearbox, a feeding chamber, a squeezing and smashing chamber and a mixing chamber, the feeding chamber and the squeezing and smashing chamber are internally provided with dual screws driven by the motor and the gearbox, the feeding chamber is provided with a feeding port, and the mixing chamber is provided with a liquid inlet and a mixedmaterial outlet; the smashing machine supplies the smashed raw materials to the feeding port, a biogas slurry pump pumps biogas slurry from the pretreatment tanks to supply the slurry to the liquid inlet, and after solid-liquid mixing in the mixing chamber is achieved, the mixture is conveyed to the pretreatment tanks. By means of the system, the raw materials such as dry straw can be precisely metered and continuously put, improvement of the working environment is facilitated, the labor cost and the energy consumption are reduced, and the fermentation effect is improved.

Description

Technical field [0001] The invention belongs to the technical field of biogas engineering, in particular to a feed and pretreatment system for biogas engineering raw materials. Background technique [0002] Biogas engineering technology is a rural energy engineering technology that takes the development and utilization of biomass resources as the object, obtains energy and controls environmental pollution, and realizes a virtuous cycle of agricultural ecology. It is to produce biogas by anaerobic fermentation of biomass raw materials in the biogas fermentation tank, so that the biomass in the biomass raw materials can be slowly released in the form of combustible gas such as biogas, so as to realize the efficient and clean energy of biomass resources such as crop straws It can not only effectively solve environmental pollution problems, but also produce biogas biomass energy, which is one of the effective ways to solve energy and environmental problems. [0003] In the prior art, ...
