Description

TECHNICAL FIELD

[0001] The utility model belongs to dust concentration monitoring technical field, concretely relates to a monitoring device for monitoring dust concentration and temperature synchronously. BACKGROUND

[0002] In industrial production, dust explosion accidents of dust removal system occur frequently, one of the main reasons is that the dust removal system lacks effective monitoring and early warning measures. At present, the source of floating dust in China's industrial production is various and complex, and the composition and particle size of dust from different sources are quite different, which brings serious challenges to reliable dust monitoring. At the same time, if the internal dust concentration is very high when the dust removal system is operating, the precision of dust monitoring will be reduced, and the measuring range of monitoring will be limited, so that accurate monitoring of dust concentration cannot be realized, and the risk of explosion cannot be effectively monitored, warned and disposed in emergency.

[0003] The existing dust concentration measurement methods can be divided into sampling method and non-sampling method. The sampling method measures part of the representative dust-containing gas in the measured area, such as filter membrane weighing method and beta ray method; the non-sampling method directly measures the dust concentration by using the physical and optical properties of dust, including but not limited to light scattering method, light absorption method and charge induction method. Among them, the filter membrane weighing method is a compliance dust concentration checking method, its measurement result is accurate, and it is usually used as a calibration method for other measurement techniques, but it cannot monitor dust concentration data in real time; the beta ray method is not affected by the chemical and surface properties of dust, and there is no error accumulation, but the system requires various shielding measures, which is not suitable for wide application in industrial places; the light scattering method has high time resolution and can provide high accuracy at low dust concentration, but when applied to poor industrial environment, it is easy to cause blockage of dust extraction pipe and pollution of sensing element; the light absorption method is simple in operation and mature in technology, but due to the limitation of sample cell light path length, the measurement result is more accurate at high dust concentration, and it is easily affected by environment and dust properties. The above methods cannot be applied to dust concentration monitoring and early warning of dust system, therefore, it is urgent to provide a monitoring device for synchronously monitoring dust concentration and temperature to realize reliable monitoring and early warning of industrial dust removal system and provide strong technical support for production safety decision-making.
