Embodiment 1

[0034] An environment-friendly biogas generation system for feces, such as figure 1As shown, it includes a biogas digester 1, a feces storage tank 2 communicated with the biogas digester 1, and the biogas digester 1 includes a biogas digester body 13 having an exhaust port, a feed port 11 and a discharge port 12; the biogas digester body The feed port 11 in the 13 is connected with a feed pipe 18 extending into the bottom of the digester body 13;

[0035] The material outlet of the feces storage tank 2 is communicated with the feed port 11 through the connecting pipe 3; an overflow device is installed in the biogas tank body 13, and an overflow port is provided on the top of the biogas tank body 13; the overflow device includes An overflow pipe with one port extending into the biogas slurry; the other end of the overflow pipe communicates with the overflow port, and the overflow port is connected with an overflow outer pipe 6, and the feed port of the overflow outer pipe 6 is ...

Embodiment 2

[0051] The difference between this embodiment and Embodiment 1 is that the structure of the overflow device is further optimized in this embodiment, and the specific settings of this embodiment are as follows:

[0052] The overflow device also includes a floating plate 14 placed on the surface of the biogas slurry in the biogas tank body 13, and a float 15 fixed below the floating plate 14; the overflow pipe includes an overflow that runs through the floating plate 14 and extends into the biogas slurry Pipe 17, and a connecting hose 19 with one end in communication with the top port of the overflow inner pipe 17 and the other end in communication with the overflow port; the overflow inner pipe 17 is fixed on the floating plate 14 and is set to extend into the biogas slurry The length of the overflow inner pipe 17 is L, and then L is less than 20cm.

[0053] Through the setting of the structure of the present invention, the scum in the biogas slurry can be effectively isolated ...

Embodiment 3

[0055] The difference between this embodiment and Embodiment 2 is that the structures of the floating plate 14, the float 15 and the connecting hose 19 are further optimized in this embodiment, and the specific settings are as follows:

[0056] There are a plurality of floats 15 below the floating plate 14 , and the floats 15 are in a conical structure with a large top and a small bottom, and vent holes 16 are arranged on the floating plate 14 between the floats 15 . The floating plate 14 is made of a hard plastic plate, and the float 15 is made of foamed plastic, and the floating plate 14 floats on the surface of the biogas slurry through the action of the float 15 .

[0057] The connecting hose 19 is a stainless steel metal hose, and the length of the connecting hose 19 is the same as the height of the inner wall of the biogas digester body 13 . The length of the L is 5-10 cm, and the height of the float 15 is at least 1 cm smaller than the L.

[0058] Through the setting o...

Abstract

The invention discloses an environment-friendly biogas generation system for excrement. The environment-friendly biogas generation system for excrement comprises a biogas tank and an excrement storagetank communicated with the biogas tank; the biogas tank comprises a biogas tank body with a feeding port and a discharging port; the feeding port in the biogas tank body is connected with a feeding pipeline stretching into the bottom of the biogas tank body; a material outlet of the excrement storage tank is communicated with the feeding port through a connecting pipeline; an overflowing device is arranged in the biogas tank body; an overflowing port is formed in the top of the biogas tank body; the overflowing device comprises an overflowing pipe; the port of one end of the overflowing pipestretches into biogas slurry; the other end of the overflowing pipe is communicated with the overflowing port; the overflowing port is communicated with an overflowing outer pipe; the overflowing outer pipe is positioned at the outer part of the biogas tank body; the discharging port is positioned in the position of the bottom end of the biogas tank body; a stop valve is arranged on the discharging port; and one one-way valve is arranged on each of the connecting pipeline and the overflowing outer pipe. The environment-friendly biogas generation system for excrement has the advantages of automatically feeding and discharging.

Description

technical field [0001] The invention belongs to the field of excrement treatment, and in particular relates to an environment-friendly biogas generation system for excrement. Background technique [0002] Biogas is a combustible gas produced by microbial fermentation of organic matter in an anaerobic environment under certain conditions of temperature, humidity, and pH. [0003] With the development of our country's economy and social progress, the life of urban residents has been further improved, but there are still many problems in the life of rural residents. Due to frequent human activities, a large amount of energy consumption, and a large amount of open-air stacking of straw and livestock and poultry manure, etc., have caused a large amount of carbon dioxide emissions and aggravated the greenhouse effect. [0004] In order to build a well-off society in an all-round way, it is very necessary to build a new socialist countryside. This requires the grand goal of devel...
