NOVELTY - Plug-flow type methane tank solar energy triplet warming device, comprises a solar greenhouse (1) equipped besides a methane tank. The solar greenhouse is equipped with a sunlight plate thermal cell (5). The sunlight plate thermal cell is equipped with a sunlight plate thermal hydrolysis acidification pool (2), a sunlight plate thermal measuring heating pool (3) and a sunlight plate thermal biogas slurry backflow pool (4). The sunlight plate thermal hydrolysis acidification pool is connected with the sunlight plate thermal measuring heating pool through a channel.    USE - The device is useful for treating high concentration organic manure in large scale farms.    ADVANTAGE - The device ensures stable operation, good treatment effect, and has low investment cost; uses solar energy to warm and heat the raw materials, and improves the utilization ratio of renewable energy sources.    DETAILED DESCRIPTION - Plug-flow type methane tank solar energy triplet warming device, comprises a solar greenhouse (1) equipped beside the methane tank. The solar greenhouse is equipped with a sunlight plate thermal cell (5). The sunlight plate thermal cell is equipped with a sunlight plate thermal hydrolysis acidification pool (2), a sunlight plate thermal measuring heating pool (3) and a sunlight plate thermal biogas slurry backflow pool (4). The sunlight plate thermal hydrolysis acidification pool is connected with the sunlight plate thermal measuring heating pool through a channel. The sunlight plate thermal measuring heating pool and the sunlight plate thermal biogas slurry backflow pool are separately connected with the methane tank, and the sunlight plate thermal measuring heating pool is further connected with a solar energy collecting device equipped outside the solar greenhouse.
