I would like to ask: Are detectors installed in environments at risk of dust explosions? How should they be installed, and what are the relevant standards? Thank you!
Regarding dust explosion prevention, dust concentration detectors are generally used to monitor environments at risk of dust explosions. The detector can monitor dust concentration in real time; when the dust concentration exceeds the set threshold, it emits an alarm signal to enable appropriate explosion-proof measures to be taken. When setting up dust concentration detectors, the following points need to be considered: 1. The detector should be a model suitable for the specific type of dust, in order to ensure measurement accuracy and sensitivity ; 2. Select an appropriate installation location so that the detector can accurately reflect the dust concentration in the environment. It should generally be installed in areas where dust may accumulate, such as conveyor belts and warehouses ; 3. The controllers, cables, and detectors themselves must possess explosion-proof properties and comply with relevant explosion-proof standards, such as the international IECEx standards and China’s GB3836 series of standards ; 4. Regularly inspect and maintain the detectors to ensure their proper operation. The relevant standards include: 1. GB 3836.1-2010 \"Explosion-proof types for electrical equipment – Part 1: General requirements\", 2. GB 3836.4-2010 \"Explosion-proof types for electrical equipment – Part 4: Enclosed explosion-proof electrical apparatus\", 3. GB/T 20104-2006 \"Methods for measuring solid combustible dusts\", 4. GB 12476.1-2013 \"Explosion-proof types for electrical equipment – Dust-proof enclosed electrical apparatus for use in mine environments with dust explosion hazards\". These standards can serve as a reference for you when designing and implementing dust explosion detection systems. I hope this can be helpful to you! .
The standard is incorrect; it should be GB/T 20104-2006 \"Chromatographic oxygen absorption method for assessing the spontaneous combustion tendency of coal\"
