There was an accident with the oxygen analyzer; it isn’t working. Can the electrostatic precipitator continue to operate?
Thread Content
Today, the oxygen analyzer in our plant suddenly malfunctioned and can no longer operate. The electrostatic precipitator is still running; should we shut down power to it immediately, or is there another way to keep it operating? In this case, if an emergency power cut is required for fishing, is it still necessary to seek approval from the supervisor?
It depends on your process: if electricity capture is carried out first and then pressurization, then a negative-pressure electrochemical oxygen analyzer will not be able to function; however, this is not an issue if positive pressure is used.
What was said upstairs is correct; if it’s located behind the fan, it can operate, but an automatic analysis of oxygen levels is necessary to ensure safety. It’s also important to adjust the pressure in the coke oven gas collection system so that there isn’t a negative pressure for too long – generally, there shouldn’t be any problems
If an oxygen analyzer cannot be used, it should be repaired as soon as possible; secondly, manual sample preparation should be improved. In cases like this, you should first inform your supervisor so that they can prepare mentally.
What was said about the 2nd and 3rd floors is absolutely correct; one also needs to pay attention to the stability of oxygen levels on a regular basis, and it is necessary to seek approval from management.
It was explained very clearly on the 2nd floor~~~ And in situations like this, it’s necessary to deal with the oxygen analyzer right away
Our factory has very strict requirements regarding oxygen content, as excessive oxygen levels can affect the subsequent hydrogen production process. If the instrument used to measure oxygen content fails, you can use another testing device to determine the oxygen level in the gas; however, this method is rather cumbersome. It is best to keep the oxygen content in the Electrode Tarifier below 1 percent.
Unless the electrostatic precipitator is shut down, use an oxygen analyzer to measure the oxygen content at the beginning of operation; as long as the electrostatic precipitator remains in operation, it can continue to function even if the oxygen analyzer is damaged.
There’s no problem, as you’ve been operating normally. If our electric precipitator fails, we can set a fixed value and keep operating as usual, since the possibility of an explosion is extremely low
The best solution is to install 2 sets of oxygen analyzers~ Hehe~~~ I specialize in manufacturing such oxygen analyzers~
After a failure of the oxygen analyzer, the electrostatic precipitator can continue to operate, but certain measures must be taken: 1. Report the issue to the relevant supervisors promptly so that the oxygen analyzer can be repaired as soon as possible. 2. Strengthen the regulation and monitoring of the pressure in the coke oven gas collection pipes; it must remain within the specified range. It is strictly prohibited for the pressure to fall below the designated standards, and negative pressure operation is also not allowed. 3. Enhance manual sampling and conduct timely laboratory analysis; measurements can be taken every 1–2 hours to guide production. 4. Ultimately, online monitoring must be implemented to ensure safe production.
