Anti-fouling Problem Of Seawater Plate Heat Exchanger

  Stainless steel plate heat exchanger is a new type of high-efficiency heat exchanger formed by stacking a series of metal sheets with a certain Anti-fouling problem of seawater plate heat exchangerherringbone corrugated shape. Compared with the conventional shell and tube heat exchanger, the heat transfer coefficient is much higher under the same flow resistance and pump power consumption.

  At present, the method for preventing the attachment of marine organisms is a method of continuously injecting seawater to obtain sodium hypochlorite (NaClO) by electrolysis.The actual operation shows that the sodium hypochlorite (0.9ppm) was continuously injected into the plate heat exchanger using seawater, and the total heat transfer coefficient did not change after 3 months of operation.In the summer when seaweeds and shellfish are prone to multiply, continuous injection of sodium hypochlorite can also ensure the same heat transfer performance. From the perspective of environmental protection, the use of ozone and hot water to prevent pollution is also effective, but has not yet been experimentally verified and established a corresponding technical method.
