Referring to fig. 1 and 2, the oil smoke online detection system comprises an oil smoke exhaust ventilator, a first flue, an oil smoke purifier, a second flue, a first fan, a third flue, an oil smoke concentration detector, a discharge flue, a return flue, a first electric flue valve, a second fan, a third fan and a controller; the range hood is arranged above the cooking bench and is communicated with the first flue, the oil fume purifier, the second flue and the third flue in sequence; the smoke outlet of the third flue is respectively communicated with the smoke discharge flue and the return flue, and the smoke outlet of the return flue is communicated with the first flue; the first fan is arranged in the second flue, the probe of the oil smoke concentration detector is arranged in the third flue, the first electric flue valve and the third fan are sequentially arranged in the discharge flue, and the second electric flue valve and the second fan are sequentially arranged in the return flue; the controller is respectively connected with the oil smoke purifier, the oil smoke detector, the first electric flue valve, the second electric flue valve, the first fan, the second fan and the third fan.

Through setting the return flue, when the situation that the oil smoke does not accord with the emission standard is detected, the controller controls the first electric flue valve and the third fan to be closed, and simultaneously controls the second electric flue valve and the second fan to be opened, the oil smoke which does not accord with the emission standard is pumped into the return flue and enters the oil smoke purifier again through the first flue connected with the return flue to be purified until the purified oil smoke accords with the emission standard, the controller controls the first electric flue valve and the third fan to be opened, and the second electric flue valve and the second fan to be opened, so that the purified oil smoke is discharged from the discharge flue.

The oil fume purifier and the oil fume concentration detector are all commercially available products. The oil smoke concentration detector is arranged on the third flue through a flange, and a probe of the oil smoke concentration detector extends into the third flue. Specifically, a hole for a probe of the oil smoke concentration detector to extend into is formed in the third flue, the oil smoke concentration detector is fixedly installed through a flange, and the flange can be fixed on a corresponding wall or the flue by adopting an expansion bolt; the probe of the oil smoke concentration detector extends into the third flue, and sealant is coated between the oil smoke concentration extractor and the third flue for sealing, so that smoke leakage is prevented.
