When the water tank 1 and the generator set body 2 are in use, the temperature sensors are used to detect the temperatures of the water tank 1 and the generator set body 2 respectively. Then, the exhaust gas generated by the generator set enters the air filter 3 through the connecting pipe 6 for filtration, and then enters the drainage tube 43 after being guided by the guide pipe 45.

The water pump 46 is externally connected to the sodium hydroxide solution, which is sprayed out through the nozzle 423 at the bottom of the spray plate 422 to treat the nitrogen dioxide and carbon monoxide in the gas. Then, the gas after spraying is adsorbed by the adsorption plate 421 containing activated carbon and enters the extension pipe 47. The valve on the extension pipe 47 is opened, and the gas can enter the heat exchanger 41 for heat exchange, thereby recovering the waste heat of the exhaust gas. The treated gas is discharged from the heat exchanger 41; When the water tank 1 is damaged and needs to be disassembled, the inner rod of the telescopic rod 73 is rotated on one side of the limiting plate 71 to separate one end of the inner rod of the telescopic rod 73 from the limiting plate 71, and the bottom of the limiting plate 71 is separated from the base 5. The bolts on the reinforcing plate 74 are rotated, and the limiting plate 71 and the support seat 72 can be taken out and replaced together; The temperature detection module 494 is used to detect the temperature of the water tank 1 and the generator set body 2. The gas detection module 495 calls the gas sensor 48 to detect the content of harmful substances remaining in the gas inside the purification box 42. When the content of harmful substances is lower than the predetermined value, the gas detection module 495 detects normal data. The abnormality detection module 496 is used to detect the working voltage and working current of the generator set. The acquired data can be summarized in the intelligent operation and maintenance unit 492, and then stored and backed up through the equipment management module 497. After judgment by the intelligent monitoring module 498, the alarm signal of the abnormal alarm module 499 can be triggered, thereby realizing the alarm of the box cloud platform and the control terminal 493, and realizing remote monitoring of the entire generator set.
