Use organic heat exchanger operating system has two types, namely thermal oil heat exchanger system of open and closed heat exchange system. The heat exchange system expansion tank exhaust pipe directly connected directly with the outside air heat exchanger system is called open heat transfer systems; expansion tank and air separation of the heat transfer system called closed heat exchange system. Now make a brief presentation on the operating characteristics of the two heat transfer system respective advantages of using the system. Use HTF medium heat exchanger system is open to expansion tank exhaust pipe directly connected to the atmosphere, waste recycling conducting oil, without increasing the ancillary equipment, process systems are relatively simple and easy to operate. At present, most domestic conducting oil heat exchanger used is an open system. I hope this will be helpful to explain more details please sustained attention site information. Hot oil conduction system should be designed to strive to make HTF thermal decomposition and oxidation to a minimum, therefore, the system should be designed to meet the following technical requirements: a reasonable pump selection, head and flow sufficient to ensure that the pipeline (especially furnace part) is greater than the minimum flow rate of the flow rate of oil required turbulence. Two, to meet the temperature requirements of the premise, the oil in the furnace flowing shorter the better. Third, the lowest part of the oil sump of the high minimum should be higher than the highest point of the heat transfer system of 3m or more, in order to facilitate the formation of a stable and start emptying the recycle loop, chemical synthesis biphenyl HTF and reduce the high oil sump temperatures. Fourth, the off-type heat transfer systems, high fuel tank should have sufficient capacity to ensure that the oil temperature significantly lower than the operating oil tank (GB24747-2009) requirements for tank oil temperature below 100 ℃, Zhoushan HTF, the general control of less than 60 ℃ more appropriate, high temperature synthetic heat transfer oil, the lower the oil temperature high slot, the contact with air oxidized oil level will be reduced to meet the "cold oil replacement operation" on oil demand. High capacity should meet HTF expansion tank needs at the highest temperature of. Fifth, the maximum operating temperature above 300 ℃ of heat transfer systems should be closed loop system design.
