Abstract
The invention discloses a building method of a biogas digester. The method is characterized by including the following steps that setting-out is conducted according to the design size; a digester pit is dug; a reinforced concrete digester base of a set size is built in the digester pit, wherein the digester base is cylindrical; an arch top cover is spirally built at the upper end of the digester base with bricks, wherein the arch top cover and the digester base serve as a biogas digester base body; one side of the bottom end of the biogas digester is provided with a discharging port, and the top cover is provided with a gas outlet and a feeding port; the exterior of the biogas digester base body is paved with a rebar mesh and three sand-cement coatings, and the inner wall of the biogas digester base body is brushed with cement paste three times. The biogas digester built through the method is solid and durable and does not crack or leak gas or water. The method is beneficial to development, application and popularization of the new energy of biogas.
Description
Technical field
The present invention relates to a kind of preparation method of methane-generating pit, belongs to technical field of new energies.
Background technology
Biogas is that a kind of straw and human and animal excreta of fermentation in new forms of energy, methane-generating pit is produced outside biogas, its methane liquid
And tunning is fertilizer, green plantss cultivation can be promoted to plant application of organic fertilizers, be conducive to health.But
It is that current biogas is promoted the use of and encounters exceptional hardship, one of them is the easy gas leakage of methane-generating pit, and oxygen enters methane-generating pit, and destruction is detested
The growth and breeding of oxygen bacterium, so that methane-generating pit cannot produce biogas.
The purpose of the present invention, is to provide a kind of preparation method of methane-generating pit, and the methane-generating pit prepared using the present invention is firm resistance to
With, it is air tight, be conducive to promoting the use of for biogas.
The content of the invention
It is an object of the invention to provide a kind of preparation method of methane-generating pit, using methane-generating pit made by the inventive method, no
Gas leakage, sturdy and durable, long service life, are conducive to promoting the use of for new forms of energy biogas.
Using technical scheme be：
A kind of manufacture method of methane-generating pit, it is characterised in that comprise the steps：
By design size setting-out, Wa Chikeng, the stall of the armored concrete being sized is built in the hole of pond, stall is cylinder
Shape, in stall upper end, arch top cover is built in brick rotation, and arch top cover is methane-generating pit matrix with stall.
There is discharging opening methane-generating pit bottom side, there is gas outlet and charging aperture on top cover.
Bar-mat reinforcement is spread outside methane-generating pit matrix and adds three layers of husky cementitious coating and methane-generating pit matrix inwall three cement mortars of brush.
The methane-generating pit prepared with the inventive method is sturdy and durable, is not cracked, air tight, water-tight.
The present invention is conducive to the exploitation of biogas new forms of energy and promotes the use of.
Description of the drawings
Fig. 1 is the biomass pool structure schematic diagram of the present invention.
Specific embodiment
Embodiment one
A kind of preparation method of methane-generating pit, it is characterised in that comprise the steps：

Soil matrix seat, wall thickness 120mm.
3）, in the upper end brick rotation of pedestal 1 set arch top cover 2, the inside and outside wall of top cover 2 concrete brushing and the thickness one of pedestal 1
Sample, and be biomass pool body for an overall structure.
4）, be provided with biomass pool body arch top cover 2 charging aperture 3 and gas outlet 4, discharging opening 5 is left in biomass pool body bottom,
Discharging opening internal diameter is 1.2m, and the bar-mat reinforcement 6 of 100 100mm is laid on biomass pool body outer wall, then erects and applies the thick of 15-20mm thickness
Husky cement layer 7, bar-mat reinforcement is embedded in rough sand cement layer, wet curing 12-24 hours, then laterally brushes husky cement layer 8, thick
10-15mm, vertically applies again fine sand cement layer 9, thick 10-15mm, wet curing after wet curing 12-24 hours.
5）, from discharging opening 5 enter biomass pool body in, one layer of cement mortar of vertical brush, slightly dry one layer of cement mortar of horizontal brush again, slightly
It is dry, last one layer of cement mortar of vertical brush again.
6）, seal charging aperture, discharging opening and gas outlet, suppress（Water or air pressure）, without leakage phenomenon after, from discharging opening by repairing
Expects pipe 10 arrives ground.
7）, backfill, compacting.The methane-generating pit arch top cover upper end 400-450cm that bankets is thick, obtains final product.
