[0032] The working principle is as follows:

[0033] The garbage inside the fermentation chamber starts to ferment under the action of high temperature. The internal methane concentration and pressure are understood by observing the methane sensor, the top gas pressure sensor and the gas pressure sensor. The biogas can be collected in time by controlling the first electric control valve and the second electric control valve. The biogas at the top and the bottom of the fermentation field is transported to the multiple bends by the upper end biogas collection pipe and the collection pipe assembly under the action of the negative pressure pump, and is cooled by the refrigeration assembly to make it flow out of the condensed water. The condensed water flowing out of the multiple bend water outlet pipe flows to the condensed water collection tank for further condensed water filtration. The dried biogas flows to the biogas collection tank for further desulfurization, deoxygenation and decarbonization treatment.

[0034] When cleaning the small holes and the grid holes, the first electric control valve and the second electric control valve are closed, the pressurizing pump assembly is started to pressurize the collection pipe, so that the gas flow passes through the small holes and the grid holes, playing a cleaning role on the small holes and the grid holes, preventing them from being closed and blocked, and better collecting the biogas.
