The coal powder silo process analysis system is an important equipment to ensure industrial production safety. It can continuously monitor the content of combustible gases and oxygen in the coal powder silo in real time, and can timely detect potential safety hazards such as explosion risks. Through alarm and interlock control measures, it greatly reduces the possibility of accidents and ensures the safety of equipment and personnel. By adopting sensor technology and multi parameter detection technology, the concentration of various gas components can be measured with high accuracy and stability, providing accurate data support for the control and regulation of the production process; Equipped with functions such as automatic sampling, automatic blowing, automatic drainage, and automatic analysis output, it reduces manual intervention, improves work efficiency and system reliability, and reduces errors caused by human factors; By analyzing the gas composition in the coal powder silo, data guidance can be provided for the adjustment of blast furnace production processes, helping operators to adjust production parameters reasonably and achieve better combustion efficiency and energy utilization.

Precautions for using the coal powder silo process analysis system:

1. Strictly control inventory and storage time: It is strictly prohibited to store coal powder excessively, and at the same time, avoid storing coal powder in the warehouse for too long to reduce the risk of spontaneous combustion.

2. Install explosion-proof facilities: Install explosion-proof valves on the coal powder system pipelines, and install explosion-proof doors on equipment such as coal powder silos, separators, and cyclones. The area of the explosion-proof door is calculated based on the equipment volume ratio, and its frame is ensured to have sufficient strength and sealing performance. Once the explosion-proof valve (door) bursts, the equipment should be stopped immediately and the fire source should be cleared. It can only be restarted after repair.

3. Install temperature monitors: Install temperature monitors in key areas such as coal powder silos, separators, and cyclones to monitor the temperature of each part for any abnormalities at any time, in order to prevent coal powder from self ignition and explosion caused by high temperatures.

4. Prevent powder accumulation in pipelines: The coal powder system pipeline must not have horizontal sections to prevent and reduce the accumulation of coal powder in the pipeline.

5. Keep the equipment interlocking intact: The mechanical equipment of the coal powder preparation system should have interlocking devices and maintain good working condition. When equipment accidents occur, it can automatically stop in a timely manner to prevent the accident from escalating.

6. Explosion proof requirements for electrical equipment: Electrical equipment in the coal powder preparation system should meet explosion-proof requirements to prevent explosions caused by electric sparks.

7. Regular calibration of measuring points and alarm devices: For temperature, pressure, flow and other measuring points and alarm devices in the powder production system, they should be calibrated regularly to ensure their effectiveness.

8. Reduce the setting of horizontal pipe sections: In the design phase of the powder production system, the setting of horizontal pipe sections should be minimized as much as possible, and the entire system should be ensured to have tightness, smooth inner walls, and no dead corners for powder accumulation.

9. Follow design specifications: The design of coal bunkers, powder silos, powder and powder feeding pipelines, powder system valves, explosion-proof pressure, and explosion-proof doors must strictly comply with relevant specifications.

10. Equipped with fire protection and inert filling system: For coal types with strong explosive characteristics, the powder production system needs to be equipped with corresponding fire protection and inert filling systems, and ensure that its steam (gas) source is stable and the drainage meets the design and operation requirements. At the same time, regular maintenance and inspection should be carried out.

11. Installation of loosening device: The raw coal silo should be equipped with a loosening device with appropriate performance to prevent problems such as blockage, shed coal, compaction, or local emptying of the raw coal silo.

12. Strengthen the management of explosion-proof doors: Strengthen the inspection and management of explosion-proof doors to ensure that the explosion-proof film has sufficient explosion-proof area and specified strength. At the same time, pay attention to the direction and range of the ejected material once the explosion-proof door is activated to avoid endangering personal safety and equipment damage.

13. Ensure that the connection parts are tight and smooth: During the system installation process, the tightness and smoothness of the connection parts should be ensured to prevent local powder accumulation.

14. Do a good job in "three separation" and debris removal: do a good job in removing impurities from the coal entering the furnace to ensure the normal operation of the pulverizing system.
