Description

Technical Field

[0001] The utility model relates to the technical field of smoke concentration monitoring, in particular to a probe used for smoke concentration monitoring. Background Art

[0002] Smoke concentration monitors are widely used in dust removal efficiency monitoring, combustion efficiency monitoring, dust concentration measurement in industrial manufacturing processes, and dust monitoring in workshops and factories. Traditional smoke concentration detectors mostly use the laser penetration method. When a beam of monochromatic light passes through a flowing medium containing oily particles, its light intensity will decay due to the absorption, scattering and reflection of the particles, so the smoke concentration can be deduced from the formula; later, a smoke concentration measurement method based on the principle of laser backscattering appeared. A stable laser signal passes through the flue and irradiates the smoke particles. The irradiated smoke particles will reflect the laser signal, and the reflected signal intensity changes positively with the smoke concentration, so the smoke concentration of the flue can be calculated through a specific algorithm. However, whether it is the laser penetration method or the laser scattering method, the measurement of smoke concentration depends on optical principles, so it is usually crucial to maintain the optical path.

[0003] At present, most smoke monitors are installed on the flue through flanges. The installation point on the flue is opened and the embedded flange is fixed, and then the smoke monitor is installed through the transition flange on the smoke detector. Generally, manufacturers recommend that the maintenance cycle of optical concentration monitors should not be more than one month. In places with high smoke concentration, the maintenance cycle should be shorter. It is recommended to clean the lens once a week; when the optical window is dirty with smoke, it must be cleaned, otherwise it will affect the accuracy of the measurement results.
