Safety explosion-proof device and working method for continuous monitoring of material fermentation

Abstract

A safety explosion-proof apparatus for continuously monitoring material fermentation and an operating method thereof are provided. In large-scale biogas fermentation process, a fermentation tank is made from an opaque material, such as concrete, and is completely sealed and dark, and providing a probe or a viewer to monitor materials in real time is required; a mark may be left on the surface of a monitoring device by scum floating up during stirring, and observation is blocked; fermentation produced gas contains flammable combustible gas and little device-corrosive gas, resulting in influences on monitoring stability. The safety explosion-proof apparatus comprises a fermentation tank, a seal cover and a heating tape; a pressure valve is mounted at the left top of the fermentation tank and is connected with a water incoming pipe, the water incoming pipe is connected with a nozzle, a glass seal hood is mounted at the upper left of the fermentation tank, a heating fan and a lighting probe are fixed in the glass seal hood, the lighting probe is connected with an external conductor, the external conductor is connected with a display, and an alarm is mounted on the seal cover and is connected with a pressure sensor. The safety explosion-proof apparatus is simple in structure, safe and handy.

Description

technical field

[0001] The invention belongs to the technical field of biological fermentation, and in particular relates to a safety explosion-proof device and a working method for continuously monitoring material fermentation. Background technique

[0002] Biogas fermentation refers to the process in which organic substances (such as human, livestock and poultry manure, straw, weeds, etc.) are catabolized by various microorganisms under certain moisture, temperature and anaerobic conditions, and finally form gases such as methane, carbon dioxide and hydrogen sulfide. . In the large-scale biogas fermentation process, the fermenter is made of opaque materials such as concrete, and is completely sealed and dark. The state of the material in the fermenter can only be guessed by measuring the temperature, pH value, etc., and cannot be intuitively understood. The progress of material fermentation and the condition of scum encrustation cannot make a judgment on material adjustme...
