The circulating water pipeline has a high-level vent at the top of the primary cooler, which is used to discharge non-condensable gases; water is sprayed there frequently. Research has shown that after the circulating water exits the primary cooler, it enters the return pipe through an N-shaped structure, and air blockages tend to form at the top of this N-shape. I would like to ask, is it necessary to perform high-level drainage? What are the drawbacks of cancellation?
It is necessary to have a vent at the highest point of the return pipe in the circulating water system; otherwise, the return flow will not be smooth, and the pressure-driven return of water in the cooler will not be effective. A vent must be installed at the highest point, otherwise water will spray out when the pressure of the circulation pump increases.
It is necessary to remove the air from the equipment at the start of operation; otherwise, the flow rate will be affected, and there will be significant vibration in the pipes and equipment, which in turn affects the nozzles in the cooling tower.
