Description

Technical Field

[0001] The utility model relates to the field of oil fume detection, in particular to a portable oil fume detector. Background Art

[0002] The oil fume detector is an instrument used to detect oil fume emissions in the catering industry. It can monitor the oil fume emission concentration, particulate matter concentration, non-methane total hydrocarbon (NMHC) concentration and other indicators in real time. By using the oil fume detector, you can timely understand the oil fume emissions in the catering industry, judge the working status of the purification equipment, and improve environmental awareness and governance efficiency. At the same time, the instrument has the characteristics of high precision, real-time monitoring, remote control, etc., and can be widely used in various catering industries and oil fume treatment projects.

[0003] Existing oil fume detectors generally use the principle of charge detection. The oil fume aerosol particles are charged through a high-voltage electric field. Under the action of the electric field force and the flowing airflow, they are pushed to the charge collection network, and a signal is generated in the circuit connected to the collection network. The change of the signal is proportional to the concentration of the exhausted oil fume. The oil fume concentration can be obtained by processing and converting the detection signal.

[0004] However, when existing oil fume detectors are actually measuring oil fume, they are generally placed close to the oil fume to detect the composition of the oil fume. Therefore, the oil in the oil fume will be adsorbed on the equipment during the detection. The equipment used for smoke measurement is generally more sophisticated equipment, and the accumulation of oil fume may cause the measurement accuracy of the equipment to decrease.
