In order to ensure the safe and stable operation of the equipment, after two years, the company once again dredged the 2# natural cooling tower.

This dredging was carried out according to the advance plan, using the time when the three pumping-condensing generator sets were shut down and only the back-pressure generator sets were operated. A total of 24 people participated, including 10 people from the 309 workshop, and 14 people from the 107 workshop, 111 workshop and purchasing department outside the administrative department. Preparations began on July 31, and dredging was officially carried out on August 1, which lasted a week.

The dredging work is dirty and tiring, the sludge is deep, and it has not been naturally dried. It is difficult to clean up, but everyone is not afraid of high temperatures, hardships and dirty, and full of energy. In order to prevent heatstroke and cool down, and provide logistics support, the administrative department arranged for restaurant staff to prepare mung bean soup, watermelon, and pancakes to quench their thirst and replenish physical strength, effectively ensuring the health of employees and the smooth progress of dredging work.

The dredging work of cooling towers demonstrates Qiyuan people's code of conduct of "working together as a company". It is with this spirit that Qiyuan's style and charm remain unchanged.
