One.Foreword
The deaerator is a special type of low-pressure thermal deaerator.
In the boiler feed water treatment process, deoxygenation is a very critical step. Oxygen is the primary corrosive substance in the feed water system and boiler. The oxygen in the feed water should be removed promptly, otherwise, it will corrode the boiler's feed water system and components. The corrosion will produce ferric oxide, which can enter the boiler, settle or adhere to the boiler tube walls and heating surfaces, forming difficult-to-dissolve iron scale that leads to poor heat transfer. Moreover, corrosion can cause pitting on the inner walls of the pipes, increasing the resistance coefficient. Severe pipe corrosion can even lead to pipeline accidents. The national regulations stipulate that the evaporation capacity is greater than or equal to2Steam boiler with a capacity of tons per hour and water temperature greater than or equal to95℃All our hot water boilers are deoxygenated. For many years, numerous boiler water treatments have been seeking a cost-effective deoxygenation method for tap water. Lianyungang Jiu Sheng Power Auxiliary Equipment Co., Ltd. has years of experience in designing and manufacturing deoxygenators.JSNCYIn-built Oxygen Remover Series Type(Also known as the new type of internal oxygen remover, internal spray oxygen remover)Advanced design and manufacturing techniques are employed, offering numerous advantages over conventional deaerators in the same industry. Currently, several companies in China have adopted the built-in deaerator technology, with all operational enterprises achieving excellent performance results.
Two.Deaerator working principle
The deaerator generally includes two working processes.:
1.A single oxygen removal: Water that has not been deoxygenated enters the deoxygenation pipeline through the inlet, is sprayed out through nozzles, forming a mist. The mist falls through the liquid-gas mesh and thoroughly mixes with the steam entering through the steam inlet. This causes the misty water to reach the deoxygenation temperature, with most of the oxygen in the water being released and expelled through the exhaust port, thus completing the first stage of deoxygenation.
2.Deaeration II: The purpose of secondary deaeration is to maintain the tank's temperature consistently at the deaeration level to maximize the deaeration effect. This is achieved by heating the already deaerated water through the auxiliary heating port at the bottom, causing any oxygen not precipitated during the first deaeration to fully precipitate, significantly reducing the oxygen content in the water. At this point, the secondary deaeration is complete.
Three.Integrated oxygen remover structure
JSNCYThe type series integrated deaerator is composed of components such as a steam-water mixture heater, tank, soft water inlet coil, secondary heating and reboiling tube, insulation board, anti-foaming device, level gauge, thermometer, automatic overflow tank, safety valve, and electric valve, as shown in the figure.
