The two characteristics of plate heat exchanger and the special application of stainless steel plate heat exchanger is introduced

A seawater resistance of plate heat exchanger, anti-pollution problems when using water. Now, as a way to prevent Marine biofouling is the water in the sea water continuous injection time is obtained by electric decomposition method and the hydrochloric acid sodium ( NaClO) Methods. Actual operation shows that in the use of the plate heat exchanger of the water in the continuous injection of hydrochloric acid sodium ( 0. 9ppm) After the determination of operation after 3 months, the total heat transfer coefficient has not changed. Algae in the summer and shellfish breeding period, the hydrochloric acid sodium injection times in a row can also ensure that the heat transfer performance remains the same. Other methods and, from a security point of view, using ozone and hot water antifouling is effective, but has not yet been verified experiment and establish corresponding technical methods. B, the corrosion resistance of plate heat exchanger using seawater, plate material for titanium plate commonly. Titanium has excellent corrosion resistance to seawater, from related, according to the corrosion resistance of information for the sea, even up to 120 ℃, titanium plate no corrosion. In addition, for the adhesion of sea creatures into The Times of hydrochloric acid sodium can also generate a strong the dynamic membrane, thus improve the corrosion resistance of titanium plate. Use class nitrile rubber as a sealing gasket, even if the water temperature of 80 ℃, also won't produce any corrosion for it. In terms of heat resistance, when the water temperature falls below 60 ℃, won't produce thermal degradation phenomenon, long-term to ensure good sealing performance. Special application of the stainless steel plate heat exchanger: 1, stainless steel plate heat exchanger is widely used in air-conditioning system of air conditioning systems in chilled water heat exchanger, in between the cooling tower and condenser installed near the condenser plate heat exchanger can have the effect of condenser, to prevent corrosion or congestion, and can save water chiller run time in transition season. 2, the pressure of the high-rise building block in high-rise buildings, water, ethylene glycol, etc for heat transfer medium hvac system often has a very high static pressure, stainless steel plate heat exchanger as pressure resistance, high static pressure can be broken down into several parts smaller pressure, thereby reducing system for pump, valve, hot and cold water unit equipment such as pressure requirements, save equipment investment cost and operation cost. 3, stainless steel plate heat exchanger for central heating should be its compact structure, easy operation, high heat transfer efficiency, has become a city of central heating engineering in the heat exchange station of choice for heat transfer products, applicable to water Water heat exchange system, steam - Water heat exchange system and living hot water supply system, the reasonable distribution of heat energy, improve the level of thermal management play an important role.
