Blocking-proof overflow discharge device for wet type organic matter anaerobic fermentation tank and application method thereof

Abstract

The invention relates to the field of wet type anaerobic fermentation treatment of organic matters, and in particular relates to a blocking-proof overflow discharge device for a wet type organic matter anaerobic fermentation tank and an application method of the blocking-proof overflow discharge device. The blocking-proof overflow discharge device is characterized in that the blocking-proof overflow discharge device is arranged and fixed on the sidewall of the fermentation tank and communicated with the inside of the fermentation tank; one end of the blocking-proof overflow discharge device is inside the fermentation tank and the other end extends out of the fermentation tank along the length direction thereof, and a central line in the length direction of the blocking-proof overflow discharge device is arranged in a manner of forming a bevel angle of 20-45 degrees with the vertical direction of the fermentation tank; the blocking-proof overflow discharge device comprises an overflow tube, and a discharge dragon penetrates through the overflow tube. The blocking-proof overflow discharge device disclosed by the invention has the advantages of solving the problems about scabbing and blocking of an overflow discharge pipeline of the conventional anaerobic fermentation tank, and simultaneously reducing the loss of organic matters and anaerobic microorganisms during overflow discharging.

Description

technical field [0001] The invention relates to the field of wet anaerobic fermentation treatment of organic matter, in particular to an anti-clogging overflow discharge device for a wet anaerobic fermentation tank of organic matter and a use method thereof. Background technique [0002] Wet anaerobic fermentation of organic matter is a process in which anaerobic biodegradation of organic materials and generation of biogas is carried out under the condition of a moisture content of not less than 90% through the action of anaerobic microorganisms. In order to maintain a constant liquid level in the fermenter, the upper overflow discharge method is usually used. However, in the actual operation process, it was found that because the top of the anaerobic fermentation tank is prone to scum layer, under the condition of lack of disturbance, the top scum is easy to scab and block the overflow pipe, causing the fermentation tank to fail to discharge normally. In addition, the trad...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to provide an anti-clogging overflow discharge device for wet organic matter anaerobic fermentation tank and its use method according to the deficiencies of the above-mentioned prior art. The fermentation tank is arranged at an oblique angle and connected to the overflow discharge device, which solves the problem of crusting and clogging of the overflow discharge pipe of the traditional anaerobic fermentation tank; at the same time, the invention can reduce the loss of organic matter and anaerobic microorganisms during the overflow discharge process
