New full-fibre biogas digesters appear in dual streams

An oval white digester with a height of about 3 meters and a diameter of 5 meters consists of solid full glass steel. A few days ago, the author learned from the Shuangliu County Science and Technology Bureau that the entire glass-steel mobile digester was “born” in Shuangliu. As an application pilot, the technology will be promoted by 5,000 farmers in a vegetable base in Chengdu.
“Ordinary biogas digesters can produce only 0.2-0.3 cubic meters of biogas per cubic meter per day. The gas production capacity of this 'glass house' is at least 30% higher than the conventional rate.” Jiang Qiwen, a full-floating glass-steel mobile digester expert, told the author that mobile digesters It can be freely placed in ordinary rural families, as well as in farms and vegetable growing areas. After the fecal matter enters the mouth, it takes a turn in the belly of the white glass steel biogas digester. From the air outlet is the biogas that can be used for burning and lighting. Jiang Qiwen told the author that the reason for designing a white elliptical body is based on the consideration of volumetric pressure settings, and the life of a mobile digester is about 50 years.
In the end, the cost is geometrically used as a new device for biogas fermentation. What is the cost of the entire fiberglass mobile biogas digester? It is reported that the cost of constructing a concrete methane tank is about 1,700 yuan, while the cost of moving glass digesters is 2,300 yuan. However, because the tightness of the concrete methane tank is not strong, it is prone to poisoning, and 200 yuan in maintenance costs will be incurred each year. Biogas digesters can be used once and for all for 50 years. In addition, the production time of glass fiber reinforced plastic digesters is only two days (including digging pits), and is one-tenth of the concrete digesters. It is very convenient. In this way, the use of fiberglass digesters for 10 years as an example, it can save 1,400 yuan, compared with the traditional brick-concrete structure, concrete structure, semi glass steel structure of biogas digesters, a lot of advantages. It is reported that, in addition to being an alternative source of energy for daily lighting and fuel, biogas also has an “uniqueness”—killing parasitic diseases of vegetables. The purity of biogas produced in a glass-steel digester is high. A pool of 1-3 acres of vegetable greenhouses is buried in a pool of biogas. Within 15 minutes, most of the pests can be killed. Moreover, high-purity biogas can also be used as an organic fertilizer to prevent crop residues.
The benefit of 5000 vegetable households According to the staff of the County Agricultural Development Bureau Agricultural Office, the biogas application technology has been listed in Chengdu Science and Technology Special Support Project. As the first batch of pilots, the entire glass-steel mobile biogas digester technology will be promoted in 5000 vegetable planting bases, livestock and poultry farms, and some rural families throughout the city this year.
A glass-steel digester can supply dozens of households at the same time. This is an unparalleled advantage of a concrete digester. It is mainly for the purpose of renewing the concrete digester, protecting the ecological environment, returning farmland to forests, reducing environmental pollution, and turning waste into solutions. The peasant household's life fuel issues made a useful contribution. The relevant person in charge of the Shuangliu County Science and Technology Bureau told the author that all parts of the biogas digesters were made of FRP material in the factory, and the parts were delivered to the site of use, and they could be used after combined molding and installation, realizing the industrialization of production. It is a major innovation in biogas technology, with reliability, security, interchangeability, applicability, and mobility, and it can be completely manufactured. With good sealing performance, high gas production rate, maintenance-free, convenient demolition, and convenient construction, it is suitable for use in economically developed areas or areas with special geological environment conditions.
At present, 30 of them have been promoted and applied in Yilipo Village, Huangjia Town, and the first full glass steel digester demonstration base has been built in the county.
