A farmer independently developed a biogas slag extraction system in Jiangyou City

With only a simple pump-type device, the biogas slurry and biogas residue in the biogas tank can be selectively pumped to the ground, watered the vegetable fields, and washed the pig pens, increasing the gas production, saving water, and solving the people to the pool. The safety problem of bottom biogas residue--the biogas slag system developed by Jiangyou City Agricultural Energy Office was highly evaluated by the National Development and Reform Commission and relevant personnel of the Ministry of Agriculture on the 12th, and it is considered that the system is worthy of national promotion.

It is reported that farmers need only 70 yuan to install a slag extraction system. The system is currently applying for a patent.

In recent years, biogas digesters have been widely established in rural areas. However, most of the biogas slags used by farmers to dump vegetables or remove the bottom of the pond need to be uncovered. When clearing the biogas residue, people still need to go down to the bottom of the pool. With this slagging system, it is possible to extract both the thin biogas slurry and the dry biogas residue. As long as the handle of the slag extraction system is lightly lifted, the biogas slurry can be extracted. The clean water in the upper layer of the biogas digesters not only saves water, but also increases the gas production due to the stirring effect during pumping.
