Condensed water is produced in the process of steam heating and transportation, so it not only has good water quality but also contains a lot of heat. The closed condensate recovery equipment is the key equipment of the steam condensate recovery system. It can be widely used in industrial enterprises in papermaking, chemical industry, food, pharmacy, grain and oil processing, rubber, cotton spinning, printing and dyeing, wood industry and other industries with steam heating. The closed recovery of condensate in the system can also be used for the recovery of steam condensate in hotels, hospitals and civil buildings. It can conveniently and effectively change the condensate produced by the indirect steam heat exchange system to closed recovery, which is a conventional traditional open type. Renewal product for recycling condensate water tank.
Effectively recovering the condensed water of low-pressure steam under various pressures that cannot be directly used has always been a major problem for thermal energy management departments in all walks of life. For many years, the R&D team has used the principles of fluid mechanics, single-phase flow and two-phase flow, based on the theory of micro-subcooling and dynamic two-phase flow characteristics of high-temperature condensate, combined with years of research on boiler equipment, and the application of the system Technology, high and low pressure pipeline common network technology, automatic pressurization technology using steam kinetic energy, the high-temperature condensate can be smoothly led back to the condensate recovery unit under low back pressure or no back pressure, and the special characteristics of cavitation elimination are adopted at the same time The component eliminates the inducement of water pump cavitation and realizes the closed recovery of condensate. At the same time, relying on industry practical experience, continuous improvement and upgrading of recycling equipment, fully recovering the secondary flash steam of condensate, so that the energy recovery rate can reach more than 95%, reducing the loss of softened water and thermal pollution, and fully saving fuel and softened water. resource.
The condensate recovery device solves the cavitation of the water pump through the pressure regulating device in the tank, the cavitation elimination device and the special water pump. Therefore, the complete closed recovery of high-temperature condensate water and high-energy secondary steam of the condensate recovery device is realized, and the volume of the water collection container is reduced. The automatic control system is used to recover the condensed water in time, minimize the energy waste, and prevent oxygen corrosion and eliminate secondary steam.
