Problems solved by technology

Generally, it is composed of feed inlet, feed pipe, fermentation and gas storage chamber (fermentation tank and gas storage chamber are the same chamber), water pressure room (or discharge room), air duct and other parts, of which the fermentation tank and the gas storage room are in the same cavity. The water pressure room is its main basic structure. It is traditionally built with brick-concrete structure. Its disadvantages are low anti-settling ability, easy to produce cracks, and air leakage. Concrete prefabrication construction, the tank bottom and tank wall between the fermentation tank and the water pressure room are all made of concrete pouring
This method requires a large amount of cement, coarse aggregate, fine aggregate, steel bars and other materials. Not only the price of the material itself is not low, but also because all of them need to be transported, it is very difficult for the vast rural areas, especially remote hilly and mountainous areas. It is inconvenient, and even requires manpower or animal power to transfer, which undoubtedly increases the construction cost, and also deviates from the original intention of reducing energy consumption and cost

Embodiment 1

[0031] This embodiment is a solidified soil structure biogas digester (brick inner mold), and its plan view, A-A sectional view, and B-B sectional view are respectively as follows figure 1 , figure 2 , image 3 As shown, it is mainly composed of feed inlet 1, feed pipe 2, fermentation and gas storage chamber 3, water pressure room 4, air guide pipe 5, slag extraction pipe 6, feeder 7, barrel pit 8, and arch cover 9 Among them, the tank bottom 10 of the fermentation and gas storage chamber 3 and the water pressure room 4 is mainly a solidified soil layer 101 with a thickness of about 15 cm, and a cement mortar layer 102 with a thickness of about 3 cm is arranged on the surface of the solidified soil layer, and the solidified soil layer 101 And the cement mortar layer 102 forms the superimposed structure layer at the bottom of the pool, and there is also a cement mortar layer 103 of about 2 cm on the surface of the superimposed structure layer; the pool wall 11 adopts a brick ...

Embodiment 2

[0042] Present embodiment is the construction method of solidified soil structure biogas digester (prefabricated slab inner mold), comprises the following steps:

[0043] (1) After determining the position of the biogas digester, lay out the line according to the design size and dig down; while excavating the pit, crush, dry and sieve the excavated plain soil (screen hole ≤ 0.3cm); according to the design requirements Calculate the amount of soil used to build a biogas digester, and prepare the soil for use;

[0044] (2), add auxiliary material according to soil property, soil is sandy soil in this embodiment, adds cement by 2%% of soil weight, turns over and mixes evenly, makes mixture for subsequent use;

[0045] (3) Use the EN-1 soil curing agent produced by the American Lubang Company. After calculating the required curing agent according to the actual amount of soil mixed, add water to dilute it at a volume ratio of 1:220; when diluting, add it to the container first. A ...

Abstract

This invention discloses the method of solidifying the soil structure methane tank and its building method, the methane tank mainly includes those parts such as the feed mouth , the feed pipe, the ferment and gas storage room, water pressure room, the pipe for taking a residue out and carrying the material, gas-guide tube, the bottom of the ferment, gas storage room and the water pressure room is 15-20 cm thick solidification soil layer, there is 2-3 cm thick cement mortars layer in the surface of the solidification soil layer, they form tier layer of the pool bottom; The pool wall uses the inner model which is built with brick or the shell precast panel inner model to solidify the gap between the pool wall which is filled with soil and the inner model to form tier layer of the pool wall, the soil layer thickness is 15-20cm; there is 1.5-2cm thick cement mortars layer in the surface of tier layer of the pool bottom and the pool wall. The main material of the methane tank is soil, it draws on local resources, it doesn't need to transport and it is economic and convenient.

Description

technical field [0001] The invention relates to a biogas digester with a solidified soil structure and a construction method thereof. Background technique [0002] Biogas is a kind of clean energy. The use of biogas can greatly reduce the pollution and damage to the environment caused by burning fuelwood, coal or fuel oil. Moreover, compared with other energy sources, the source of biogas raw materials is convenient, no long-distance transportation is required, and the cost is low. . Therefore, especially in the vast rural areas, biogas has been more and more widely used. [0003] Rural household biogas digesters are the most important basic facilities for man-made biogas production. Generally, it is composed of feed inlet, feed pipe, fermentation and gas storage chamber (fermentation tank and gas storage chamber are the same chamber), water pressure room (or discharge room), air duct and other parts, of which the fermentation tank and the gas storage room are in the same ...
