How to deal with the interruption of nitrogen during the operation of the nitrogen generator? Some customers may encounter the interruption of nitrogen during the operation of the nitrogen generator. When this happens, don't panic. If the nitrogen pressure can get up temporarily, you don't have to close the valve.
To turn off, turn off the nitrogen, disconnect the pipeline, and then turn off the nitrogen and the air defense valve. When the temperature of nitrogen drops to 50 ℃, we change the valve and try the leakage. The outlet valve of electric heating is open. (after asking that the quality and pressure of nitrogen and nitrogen are normal, carefully check that there is no leakage point and the valve is opened and closed correctly.
After replacing the pipeline with nitrogen, adjust the flow rate to 300 m3, close the vent valve of the reactor, open the upper and lower valves of the reactor, release the empty valve, blow the nitrogen pipeline, connect the rubber hose, and then know that the nitrogen pressure drops suddenly, so the power should be cut off and heated in time. Open the nitrogen main valve until the flow is about 7 to 10 cubic meters. After the electric heating is turned on for preheating, the valve is directly opened to close to the original valve opening for heating. If there is a problem with nitrogen or nitrogen quality, it is necessary to cut off the power supply, turn off the nitrogen, turn off the nitrogen, and turn off the vent. When opening, first open the nitrogen valve, vent valve, and then open (and replace the pipeline first) the nitrogen valve.
Remember that in the initial stage of the last activation and heating exothermic reaction, when the nitrogen was removed, the temperature at the top of the reactor decreased and then increased. It seems that we should be flexible and not rigid. Inert gas and combustible gas, start stop sequence is not the same, need to consider safety. Because at different stages, the same problems appear, the symptoms are not the same, and the treatment is different, so we can't make a mistake. Everything is for safety, everything else is guaranteed.
