In the air separation equipment, the anti-entrained water pressure interlocking of air cooling tower plays an important role in safety protection.
The air cooling tower is the key place for air cooling, where the air and cooling water exchange heat. However, if the pressure is abnormal during operation, it is very easy to cause water entrainment problem, affecting the stable operation of equipment and product quality. The pressure interlock system monitors the relevant pressure parameters.
When the outlet pressure of the air compressor is abnormally reduced, it means that the air entering the air cooling tower may be insufficient, the air cooling effect will become worse, and the water vapor is more likely to condense and be entrained. At this time, the pressure interlocking responds quickly and automatically adjusts the subsequent process parameters to reduce the air flow entering the air cooling tower and prevent the water entrainment due to uneven cooling caused by insufficient air.
If the pressure of circulating water pump fluctuates and the cooling water supply is unstable, the air cooling will also be affected. The pressure interlocking can detect this change in time, regulate the cooling water flow or give an alarm to avoid water entrainment due to cooling water problems.
Through this accurate pressure interlocking control, the real-time control of the operation status of the air cooling tower is realized, the efficient, stable and safe operation of the air separation equipment is guaranteed, and the subsequent air separation processes are provided with reliable guarantee.
