Electrolyzer on fire

I’m not sure which manufacturer’s electrolyzer you’re referring to, but I think the principle is more or less the same in all cases. An electrolyzer cannot catch fire unless oil is deliberately poured on it to start a fire. Both DCS and SIS systems have multiple interlock shutdown mechanisms; in other words, when there are abnormalities in factors such as voltage, current, or brine flow, the electrolyzer shuts down automatically, giving enough time to check the issue and resolve it. So, such problems do not occur.

For the tanks used in chlorine processing, it’s better to be prepared for anything; if something does happen, there are measures in place to deal with it

It can catch fire; when there is severe leakage at the cathode of the electrolyzer, it can catch fire

Cathode leakage can cause an interlocked shutdown due to sudden changes in either hydrogen pressure or the flow rate of the cathode circulation fluid; how could it get serious enough that a fire is the only indication? It’s impossible; humans are the most unpredictable factor. Even if that factor is excluded, an interlock shutdown will still be triggered.

This involves installing automatic fire suppression systems or fire extinguishers, depending on factors such as the regional fire protection rating and the flammability of materials. It also includes a range of safety management tasks such as risk analysis, development of preventive measures, preparation of emergency plans, communication planning, emergency drills, and evaluation.

If the fire cannot be extinguished using a fire extinguisher, the following steps must be taken: 1. First, it is necessary to maintain positive pressure in the cathode system, so as to prevent hydrogen backflow from causing a more serious disaster. 2. The control system is stable; gradually reduce the current load of this tank and isolate it from the system. 3. Fill the cathode system of the ignition tank with sufficient nitrogen. 4. Disconnect the rectifier switch after the current drops to zero. 5. At this point, as the current drops to zero, no more hydrogen is produced in the tank; coupled with the filling of large amounts of nitrogen, the intensity of the fire decreases. 6. The remaining step is to use a fire extinguisher to put out the fires that are still burning in the surrounding area. It’s just my personal opinion; I hope everyone will actively participate in the discussion.

1. Ensure that the current in the faulty cell is reduced based on the chlorine-hydrogen pressure difference. 2. Fill the cell with nitrogen to maintain a positive pressure inside it. 3. Isolate the gas phase of the faulty cell. 4. Keep a continuous supply of catholyte and refined brine for the cell. 5. Once the current in the faulty cell drops to zero, disconnect its rectification system. 6. Extinguish any remaining sources of fire.

The voltage interlock no longer functions, and incidents occur frequently where the blockage of the brine feed pipe leads to a rapid rise in voltage, causing the electrolyzer to catch fire.
