1. Introduction to vacuum degasser:
Vacuum degassing adopts the principle of differential pressure degassing, which can be applied to any water system. Its strong degassing capacity can ensure safe and rapid removal of free gas and dissolved gas in the system, so that the system can operate safely and reliably.
2. Operating principle of vacuum degasser:
According to Henry's Law, the solubility of gas in water is related to water temperature and pressure, and is proportional to the pressure of gas at a certain temperature. Under a certain pressure, it is inversely proportional to the water temperature. When the pressure on the water surface is reduced, the gas in the water can be separated at a lower water temperature to remove the gas in the water. The vacuum degasser (deoxidizer) releases free gas and dissolved gas in water through the vacuum generated in the machine, and then automatically Exhaust valve Remove the system and inject the degassed water into the system. The vacuum degasser repeats this cycle every 20-30 seconds. In this way, all gases in the system water will be removed eventually.
3. Advantages of vacuum degasser:
(1) It can greatly shorten the exhaust time after the initial water injection of the heating or cooling system, which is more conducive to the initial commissioning and operation of the system.
(2) Remove the gas in the system to prevent gas blockage and ensure the stability and reliability of the system during normal operation.
(3) Eliminate water pump Cavitation, reduce system operation noise.
(4) The oxygen in the water is removed, which will reduce the aerobic corrosion of the system and extend the service life of the equipment.
(5) Since the gas in water is removed, Heat exchanger There is no gas bubble on the surface, which improves the heating efficiency.
(6) The working time and cycle of the gas turbine can be adjusted as required.
(7) The capacity of a single applicable system is up to 150 m3; Multiple sets can be used in parallel.
(8) The equipment is easy to install, fully automatic operation, safe and reliable, and easy to maintain.
