Design specifications for online dust detection and alarm systems in coal chemical plants?
Thread Content
This post was last edited by Wang Tianze on 2016-3-4 at 12:06. Dear colleagues, I was wondering if anyone has experience with developing online dust detection and alarm systems for the environment (air) inside coal chemical plants. After searching for a long time, I couldn’t find any relevant design standards in the petrochemical industry. However, since certain areas of these plants are classified as zones at risk of dust explosions, management requires that, in addition to online monitoring and alarm systems for flammable and toxic gases, there also need to be systems for detecting dust (coal dust). Does anyone know the design standards for online dust detection and alarm systems used in coal mining and metallurgical industries? Help needed. . . . Not very grateful! ! @zjp @chqd812 @qugd @feng*aosa
I haven’t dealt with this aspect before, so I can’t offer any help; please back the original poster up
Keep going! d=====(￣▽￣*)b
There are not many requirements for instruments used to measure steel dust in the metallurgical industry; unless it is coke oven gas, blast furnace and converter gases have a low calorific value, and therefore explosion-proof instruments are generally not required. Only the chemical industry requires it.
Hello everyone, this is the office of Auburn Systems in China. As the inventor and patent holder of electrostatic dust detectors, Auburn has been engaged in the research, development, and production of systems for online dust monitoring, as well as systems for detecting and locating leaks in dust collector bags. The company also specializes in measuring dust concentration and flow rates in gas-solid two-phase flows. Those who are interested are welcome to contact Wu at 18201477088. Thank you! The Auburn bag leakage and positioning system can effectively address such issues, helping users figure out where the problem lies when a problem occurs with the bag. During operation, dust collectors may experience issues such as bag leakage, blocked bags, and malfunctions in the solenoid valves. If these problems are not detected or addressed in a timely manner, it can lead to extensive damage and leaks, resulting in excessive dust emissions and subsequent fines. The Auburn bag leak detection and location system is applied at the back end of bag filters to prevent such issues from occurring; it enables the detection of problems in a timely manner, identifies each row of bags as well as the filter box, and alerts users to take action or replace the bags promptly. If you have such a need, please contact Wu at the representative office of the Auburn Systems in China at 18201477088. Thanks! It can be applied in areas with bag filter processes in industries such as steel, metallurgy, power generation, cement, food, pharmaceuticals, chemicals, and so on. It can also be applied to online monitoring of smoke and dust emissions!
I’m looking at relevant materials; please give some support
There are no specific standards in this industry, but the upper and lower explosion limits of coal powder can be used as a basis for design. For more details, you can contact me via WeChat at 13488680104
