Technical Field

[0001] The utility model relates to the technical field of garbage power generation, in particular to a biogas alarm structure used for garbage power generation. Background Art

[0002] Garbage-to-energy collects various types of garbage and processes them in different categories. First, high-temperature incineration is performed on the garbage with a higher combustion value (which also completely eliminates pathogenic organisms and corrosive organic matter). The heat energy generated during high-temperature incineration (the smoke generated is processed) is converted into high-temperature steam to drive the turbine to rotate, so that the forward and reverse motors can generate electricity. Second, the organic matter that cannot be burned is fermented and anaerobically treated, and finally dried and desulfurized to produce a gas called methane, also called biogas.

[0003] At present, the biogas generated in the waste-to-energy process has no alarm function after leakage, and it cannot alarm after the biogas concentration exceeds the standard, so it cannot be handled in time, which is prone to danger and cannot meet the use requirements. For this reason, we propose a biogas alarm structure for waste-to-energy. Utility Model Content
