One.Preface
The deaerator is a special type of low-pressure thermal deaerator.
In the boiler feedwater treatment process, deoxygenation is a critical step. Oxygen is a primary corrosive substance in the feedwater system and boiler. The oxygen in the feedwater must be removed quickly, otherwise, it will corrode the boiler feedwater system and components. The corrosion will produce iron oxide that enters the boiler, depositing or adhering to the boiler tube walls and heating surfaces, forming difficult-to-dissolve iron scales that lead to poor heat transfer. Moreover, corrosion can cause pitting on the inner walls of the pipes, increasing the resistance coefficient. In severe cases of pipe corrosion, pipe accidents may occur. National regulations stipulate that for evaporation capacity greater than or equal to2Steam boilers with a capacity of more than or equal to tons per hour and water temperature95℃All of our hot water boilers are deoxygenated. For many years, numerous boiler water treatments have been seeking a cost-effective deoxygenation method for constant temperature water. Lianyungang Jiusheng Electric Power Auxiliary Equipment Co., Ltd. has years of experience in designing and manufacturing deoxygenators.JSNCYInbuilt Oxygen Remover Series Type(Also known as the new type of built-in oxygen scavenger, built-in spray type oxygen scavenger)Advanced design and manufacturing techniques are employed, offering numerous advantages over conventional deaerators in the industry. Several domestic companies, both established and under construction, have adopted the built-in deaerator technology, with all operational enterprises achieving favorable performance results.
Two.Deoxygenator working principle
The deaerator generally includes two working processes.:
1.One-time Deoxygenation: Water that has not been deoxygenated enters the deoxygenation pipeline through the inlet, and is then ejected through nozzles, forming a mist. The mist falls through the liquid-vapor mesh and is thoroughly mixed with the steam entering through the steam inlet, reaching the deoxygenation temperature. Most of the oxygen in the water is then released and expelled through the exhaust port, completing the one-time deoxygenation process.
2.Deaeration Stage Two: The purpose of the second deaeration stage 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 undissolved oxygen from the first deaeration stage to fully precipitate, significantly reducing the oxygen content in the water. At this point, the second deaeration is complete.
Three.Integral oxygen remover structure
JSNCYThe type series integrated deaerator consists of components such as the steam-water mixing heater, tank, soft water inlet coil, secondary heating and re-boiling tube, thermal insulation board, antivibration device, level gauge, thermometer, automatic overflow tank, safety valve, and electric valve, as shown in the figure.
