AI Technical Summary

Technical Problem

In existing flushing methods for natural ventilation direct air condensers, a significant amount of time is required before equipment startup, and the water quality is often difficult to meet requirements, affecting the long-term operation of the equipment.

Method used

During the commissioning process, hot flushing of the natural ventilation direct air condenser is carried out simultaneously. Temporary pipes and valves are used to connect to the rainwater well. The cooling triangle is flushed and circulated for cleaning. Combined with the operation of vacuum pumps and feed water pumps, hot flushing and water quality testing are achieved.

Benefits of technology

It saves valuable time before equipment startup, improves condensate water quality, shortens equipment commissioning time, extends equipment operating cycle, and reduces material costs.
