    (1) Parameters of the PLC control system are set, and the starting condition of the fan 20 is set as the temperature of the materials in the fermentation tank reaches 80°C or the heating device in the fermentation tank heats the materials for 2 hours, the livestock and poultry dead of disease are degraded by fermentation bacteria, without odor; the starting condition of the submersible pump 23 is set to start synchronously with the fan; (2) The heating device and the crushing and stirring device in the fermentation tank are started; when the above conditions are satisfied, the fan 20 and the submersible pump 23 are started, steam is sucked in through the holes on the air suction pipe 2-4, enters the inlet of the fan 20 through the steam discharge pipe 19, and enters the steam inlet 25-2 of the condensing device 25 from the outlet of the fan 20 through the steam feed pipe 26, the steam enters the condensing cylinder 25-1 and contacts the condensing pipe 25-3, meanwhile, cooling water is lifted by the submersible pump 23, enters the cooling water inlet 25-6 of the condensing device 25 from the cooling water tank 24 through the cooling water inlet pipe 21 to enter the condensing pipe 25-3, then enters the cooling water tank 24 from the cooling water outlet 25-5 of the condenser device 25 through the cooling water outlet pipe 22, and circulates; the steam is condensed into condensed water after contacting the condensing pipe 25-3, the condensed water enters the condensed water tank 28 from the condensed water outlet 25-4 at the bottom of the condensing cylinder 25-1 through the condensed water drain pipe 27, and the collection and treatment of the steam are completed.
    In summer, when the temperature of the cooling water rises and the condensation efficiency decreases, the chiller 29 needs to be activated.
    The chiller 29 can cool the cooling water.
    The cooling water circulates between the cooling water tank 24 and the chiller 29 through the water outlet pipe 30 and the water inlet pipe 31, thereby reducing the water temperature.
    Although the specific embodiments of the present disclosure are described above in combination with the accompanying drawing, the protection scope of the present disclosure is not limited thereto.
    It should be understood by those skilled in the art that various modifications or variations could be made by those skilled in the art based on the technical solution of the present disclosure without any creative effort, and these modifications or variations shall fall into the protection scope of the present disclosure.
