Perhaps, the static seal at the front of the machine is not tight enough, allowing a small amount of gas to be drawn in； Or the clearance of the comb seal at the first stage of the turbine is large, allowing sealing gas to enter the system.
From the source, there may be the following issues along the way: 1. Membrane leakage, excessive chlorine and hydrogen content； 2. The sulfate level in the saltwater is too high, and side reactions lead to an increase in oxygen content in chlorine ； 3. Air enters due to leaks in the process pipelines or equipment ； 4. The cooling or drying system is malfunctioning, resulting in an excessively high level of water content in the chlorine ； 5. As for the sealing gas, it should be a problem on the back of the machine.
1. The purity of chlorine gas coming from the electrolyzer is low; analyze the purity of the wet chlorine gas exiting the electrolyzer； 2. There are leaks in the pipelines before the pump, the flanges, and the towers, allowing air to enter; personnel should be assigned to locate and fix these leak points ； 3. When the system is just started up, the purity of chlorine is low.
The decrease in chlorine purity ahead of the machine is due to leakage points, allowing air to enter.
In addition to the reasons analyzed above, there are also 1) issues with positive and negative water seals, 2) sampling and analysis standards, and 3) internal leakage in the valves connecting to the accident tower
If dechlorinated chlorine enters the system, it is necessary to check the purity of the dechlorinated chlorine and verify whether there is any leakage from the mechanical seal.
There is likely a leak in the negative pressure section for chlorine; it needs to be thoroughly checked. Key areas to examine include expansion joints, valve flange gaskets, drip pipes, pressure gauges, and the connections of the chlorine cooler
