Furnace type household dry-fermentation methane generator

Abstract

The invention discloses a furnace type household dry-fermentation methane generator. The methane generator with economic and practical effects, simple operation and no need of power supply support is suitable for families in vast rural areas, mountainous areas and nomad areas. The furnace type household dry-fermentation methane generator comprises a shell and a furnace type heating device and is characterized in that the shell is of a double-layered structure with a thermal insulating layer in the middle, and is provided with a feeding hole, a discharging hole, a gas delivery pipe, a pressure gauge and a thermometer, wherein the upper edges of the feeding hole and the discharging hole adopt bayonet type structures and are good in sealing performance; the furnace type heating device is a combustion furnace and is arranged at the central position in the shell, and an upper opening of the combustion furnace penetrates through the top part of the shell, is arranged above the shell, and is additionally provided with a cover; a furnace pad is arranged above the bottom part of the combustion furnace; an ash discharging hole is arranged below the furnace pad in a manner of penetrating through the shell and is provided with an ash discharging hole cover; a methane combustor is also arranged above the furnace pad. The furnace type household dry-fermentation methane generator disclosed by the invention is widely applied in the rural areas, the mountainous areas and the nomad areas and provides clean energy with low manufacturing cost and high quality.

Description

technical field [0001] The invention relates to a biogas generator, in particular to a furnace type domestic dry fermentation biogas generator. Background technique [0002] Biogas is a combustible gas that uses biomass to convert into energy. It has been popularized and used in my country for a long time, and the most common biogas fermentation ponds or fermentation tanks that can produce biogas in rural areas are mostly fixed structures made of masonry and concrete. , is simple and practical, but has many defects. Once it is built, it cannot be moved, and it is subject to large changes in regional environment and climatic conditions. The biogas digester with concrete structure in the cold north cannot be used, the gas production rate is low, and it is inconvenient to use. Someone invented The mobile fermentation tank is made of steel, and heat preservation and heating devices are used to increase the fermentation speed and solve the problem of using in winter in the north.

[0002] Biogas is a combustible gas that uses biomass to convert into energy. It has been popularized and used in my country for a long time, and the most common biogas fermentation ponds or fermentation tanks that can produce biogas in rural areas are mostly fixed structures made of masonry and concrete. , is simple and practical, but has many defects. Once it is built, it cannot be moved, and it is subject to large changes in regional environment and climatic conditions. The biogas digester with concrete structure in the cold north cannot be used, the gas production rate is low, and it is inconvenient to use. Someone invented The mobile fermentation tank is made of steel, and heat preservation and heating devices are used to increase the fermentation speed and solve the problem of using it in winter in the north. Although this device can be used in cold places and has a relatively high gas production rate, it has a complex structure. The volume is huge, the heating device consumes a lot of energy, and it cannot be used in rural areas, mountainous areas, and nomadic areas without electricity

The raw materials for gas production are often kitchen waste, livestock and poultry manure, and the slag liquid after fermentation is polluted and needs to be treated. Therefore, both the equipment cost and the use cost are relatively high, and it cannot be popularized and used among farmers in rural, mountainous and nomadic areas; the second is currently The raw materials used for gas production in the biogas generating device are kitchen waste, pig and cow manure and other wastes, all of which are used to solve environmental pollution. Wet fermentation method is adopted. Gas production cost

For the vast rural areas, how to use a large amount of straw and adopt the dry fermentation method to produce economical and practical biogas generators does not currently have such equipment, and people are urgently waiting for research and development.
