One.Preface
The deaerator is a special type of low-temperature thermal deaerator.
In the boiler feed water treatment process, deoxygenation is a critical step. Oxygen is a primary corrosive substance in the feed water system and boiler. Oxygen in the feed water should be removed quickly, otherwise, it will corrode the boiler feed water system and components. The corrosion will produce iron oxide, which can enter the boiler, settle or adhere to the boiler tube walls and heat transfer surfaces, forming an insoluble 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 output of more than or equal to tons per hour and water temperature95℃All of our hot water boilers are deoxygenated. Over the years, many boiler water treatments have been seeking a cost-effective deoxygenation method for normal temperature water. Lianyungang Jiusheng Electric Power Auxiliary Equipment Co., Ltd. has years of experience in designing and manufacturing deoxygenators.JSNCYType Series Integrated Oxygen Remover(Also known as the new type integrated oxygen removal unit, integrated spray type oxygen removal unit)Advanced design and manufacturing techniques are employed, offering numerous advantages over conventional deaerators in the same industry. Currently, several domestic companies, both established and under construction, have adopted the built-in deaerator technology, all of which have achieved good operational 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 sprayed out through nozzles, forming a mist. The mist falls through the liquid-vapor 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 one-time deoxygenation.
2.Deoxygenation II: The purpose of secondary deoxygenation is to maintain the tank's temperature at the deoxygenation level at all times to maximize the deoxygenation effect. This process is achieved by heating the deoxygenated water through the auxiliary heating port at the bottom, causing any oxygen not removed during the first deoxygenation to be fully precipitated, significantly reducing the oxygen content in the water. At this point, the secondary deoxygenation is complete.
Three.Integral oxygen remover structure
JSNCYThe type series integral deaerator consists of components such as a steam-water mixture heater, tank, soft water inlet pipe, secondary heating and reboiling tube, insulation board, anti-foaming device, liquid level gauge, thermometer, automatic overflow tank, safety valve, and electric valve, as shown in the figure.
