The deaerator is a special type of low-pressure thermal deaerator.
In the water treatment process for boiler feed, deoxygenation is a very critical step. Oxygen is the primary corrosive substance in both the feedwater system and the boiler. The oxygen in the feedwater must be removed promptly, otherwise, it will corrode the feedwater system and components of the boiler. The corrosion will produce iron oxide that enters the pot, depositing or adhering to the boiler tube walls and heating surfaces, forming an insoluble scale that leads to poor heat transfer. Moreover, corrosion can cause pitting on the inner wall of the pipes, increasing the resistance coefficient. Severe pipe corrosion can even lead to pipeline accidents. National regulations stipulate that the evaporation amount is greater than or equal to2Steam boiler with capacity of more than or equal to tons per hour and water temperature95℃All of our hot water boilers are deaerated. Over the years, many boiler water treatment projects have been seeking a cost-effective deaeration method for ambient water. Lianyungang Jiusheng Power Auxiliary Equipment Co., Ltd. has years of experience in designing and manufacturing deaerators.JSNCYIn-built Oxygen Remover Series Type(Also known as the new type of integrated oxygen removal unit, integrated spray-type oxygen removal unit)Utilizing cutting-edge design and manufacturing processes, our oxygen removal systems offer numerous advantages over conventional industry counterparts. Currently, several domestic companies, both established and under construction, have adopted our integrated oxygen removal technology, with all operational enterprises achieving favorable performance results.
Two.Deoxygenator working principle
The deaerator generally includes two working processes.:
1.A single oxygen removal: The water that has not been deoxygenated enters the deoxygenation pipe through the inlet, and is then sprayed out through nozzles, forming a mist. The mist falls through the liquid-vapor grid and is thoroughly mixed 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 precipitating out and being expelled through the exhaust port. At this point, the single oxygen removal process is complete.
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.Built-in Oxygen Remover Structure
JSNCYThe series integrated deaerator is composed of a steam-water mixture heater, tank, soft water inlet coil, secondary heating and reboiling tube, thermal insulation board, anti-foaming device, level gauge, thermometer, automatic overflow tank, safety valve, electric valve, etc., as shown in the figure.
