A Teaching Model of Intelligent Biogas Reactor

Abstract

The invention discloses a teaching model of an intelligent biogas reactor. The teaching model comprises a reactor tank; the reactor tank is of a two-layer heat-preserving drum shape, and an outer drum and an inner drum are respectively provided with a feed inlet, a biogas slurry outlet and a biogas residue outlet; the side body of the outer drum is provided with a water inlet and a water outlet; the tops of the outer drum and the inner drum are bonded through an annular connection board and capped by a cover plate; the cover plate is provided with a biogas outlet, a temperature sensor interface, a stirring bar interface, a pH value sensor interface and threaded holes; the biogas outlet is connected with a gas collection bottle through an air inlet conduit; the water outlet of the gas collection bottle is connected with the water outlet of a water-bath kettle through a conduit; a water pump in the water-bath kettle is connected with the water inlet of the biogas reactor through a water supplying conduit; after the biogas reactor is full of water, water overflows to the water-bath kettle from the water outlet through a backwater conduit. The teaching model is simple, safe and highly efficient, can carry out discharging and feeding in the process of biogas fermentation at any time and overcomes the disadvantages of poor leakproofness, easy fragmentation and incapacity of heat preservation of a traditional biogas reactor prepared from plastic or glass.

Description

technical field [0001] The invention relates to a teaching model, in particular to a teaching model of an intelligent biogas reactor. Background technique [0002] The existing biogas digester models are mainly made of ordinary plastic bottles or glass. Although the production is relatively simple, the biogas reactor made of ordinary plastic has poor airtightness, and air and water leakage often occur, while the biogas reactor made of glass is easily broken. The production process is easy to cause personal injury, and it cannot effectively keep warm, the reaction speed is slow, and the teaching and experiment cycle is long. The teaching models of these biogas reactors often only reflect the knowledge points of biogas fermentation in the process of teaching and examples, and they still do not understand the environment inside the biogas reactor and the changes in fermentation parameters. to effectively improve.
