Embodiment Construction

[0034] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0035] refer to figure 1 , the embodiment of the present invention proposes a laser scattering fume monitor, including a fuselage, a laser light source 4, a beam splitter 7, a first light receiver, a second light receiver 2, and an output processor 6 are arranged inside the fuselage;

[0036] Laser light source 4, used to emit laser beams;

[0037] The beam splitter 7 is used to divide the laser beam into a detection beam 9 and a correction beam 8. One end of the fuselage has an opening. When the monitor is working, the detection beam 9 is emitted from the opening;

[0038] The first light receiver is used to receive the scattered light 10 and convert the scattered light 10 into a first electrical signal, the scattered light 10 is formed by the detection beam 9 irradiating the oil fume in the exhaust pipe;

Abstract

The present invention provides a laser scattering fume monitor, which uses a spectroscope to divide a laser beam into a detection beam and a correction beam, the detection beam is used to detect the concentration of oil fume, and the correction beam is used to correct the intensity of a light source. The detection part of the laser scattering oil fume monitor provided by the present invention is installed outside the smoke exhaust pipe, avoiding the influence of high temperature and high humidity oil fume substances in the smoke exhaust pipe, improving the service life of the sensor, and at the same time, being less affected by the site environment and improving the anti-pollution ability At the same time, it also has a self-calibration function. The dual optical path system can self-correct the light intensity fluctuation of the light source due to environmental changes to ensure the accuracy of the detection results.

Description

technical field [0001] The invention relates to the field of oil fume monitoring, in particular to a laser scattering oil fume monitor. Background technique [0002] With the rapid development of the catering industry, the problem of oil fume pollution has become increasingly prominent and has become one of the hot spots of environmental complaints. Routine monitoring of oil fume pollution in the catering industry has also received more and more attention from the industry. [0003] Because cooking fume is emitted intermittently, the concentration is high and low at times, and the traditional detection method has high requirements for on-site testing conditions, and the samples need to be brought back to the laboratory for analysis, and the detection cycle is long. Therefore, it has become a top priority to seek a rapid and real-time detection method suitable for cooking fumes in the catering industry. At present, the common oil fume detectors installed at the discharge si...
