and the second liquid level transmitter is positioned in the second liquid storage tank and connected to the controller and is used for monitoring the liquid level height in the second liquid storage tank.
7. The performance evaluation method of the multi-working-condition oil smoke purifying device, which is characterized by comprising the following steps of:
the controller respectively controls the smoke generating device, the first drip pump, the second drip pump, the fan and the flow divider to start working, so that the first valve is closed and the second valve is opened;
the first flowmeter, the second flowmeter and the thermometer respectively send the detected data to the controller;
the controller controls the first drip pump, the second drip pump and the smoke generating device to work according to the received flow data and temperature data;
the pressure detector, the particle size detector, the TVOC concentration detector and the air speed meter respectively send the detected data to the controller;
and the controller obtains a single purification efficiency value of the oil fume purification device according to the received pressure data, the grain size data and the TVOC gas concentration data.
8. The multi-condition soot cleaning device performance evaluation method of claim 7, further comprising the controller commanding the first valve to open and the second valve to close, respectively, and obtaining the cumulative pressure drop value and the cumulative oil capacity of the soot cleaning device based on the received pressure data, the classification diameter data, and the TVOC concentration data.
9. The multi-condition soot cleaning device performance evaluation method according to claim 7 or 8, wherein the controller generates a cumulative pressure drop curve or/and a cumulative pressure drop chart of the corresponding soot cleaning device according to the received pressure data.
