Compound water congealing ready-package marsh gas generator and production method

Abstract

The invention relates to a compound water congealing ready-package marsh gas generator having a structure that the top of a shell of the marsh gas generator is provided with a gas outlet base which is provided with a gas output pipe, one side of the top is provided with a feeding port, and the other side of the top is provided with a water pressure box; and the bottom of the shell of the marsh gas generator is provided with a base. A production method is as follows: portland cement, a concrete early strength admixture, polypropylene fibers, siliceous dust, river sands, an early strength water-reducing agent, a mortar superplasticizer, trolamine, sodium nitrite, an FW type waterproof agent, water, and the like are prepared with concrete and cement mortar, a clamping fixture is paved with a plastic membrane and a fiberglass gelatinized gridding cloth, a steel wire skeleton meshwork is coated with the cement mortar and the concrete in a layering way and maintained for 10-20 hours under normal temperature and then demoulding is carried out. The invention has the advantages of ellipsoid volume, shallow embedding depth, large fermenting basal area, no fermenting blind area, good sealing of a cell body, no movable cover, convenient operation, moulded product industrial production, convenient installation and low cost and price of the cell body.

Description

Technical field [0001] The invention relates to a gas generating device, in particular to a biogas generator. Background technique [0002] Gas that produces alternative energy sources when decomposing organic matter. This gas is often called biogas because of the way it is obtained. An important component of biogas is methane, which is produced by decay or decomposition of organic matter or plants or their second-generation products. According to the prior art, a one-stage or two-stage fermentation method is adopted for this purpose, in which biogas with a methane content of 20% to 60% is obtained from organic matter by means of anaerobic fermentation, and the remaining components of the biogas are composed of 25% to 55% of carbon dioxide. Gas and less nitrogen, hydrogen sulfide and other components. [0003] The currently widely used biogas generators mainly include: water moon type biogas digesters, the vault gas storage tank is generally about 3m below the ground surface, the...

Problems solved by technology

The main disadvantages are as follows: the gas retention performance of the arched gas storage tank is poor, because the hydration substance reacts with carbon dioxide to form calcium carbonate, aluminum silicate glue and free water

Large-scale treatment devices are not suitable for household or small-scale use. Even if such devices are built in urban waste disposal sites, more than 95% of biogas digesters are used due to many problems in the structure, construction, process, use, and management of biogas digesters. After 1 to 2 years, serious leakage begins, seriously polluting underground drinking water sources and urban underground water supply pipelines

Moreover, the on-site construction of this biogas digester takes a long time, and the labor intensity is high and the cost is high.

[0004] In addition to the common biogas digesters with brick-concrete structure, there are also biogas generators made of glass fiber reinforced plastics. The manufacturing process of this kind of biogas generator is complicated and the cost is high.
