One.Introduction
Deaerator is a special type of low-temperature 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. Oxygen in the feed water should be removed rapidly, otherwise, it will corrode the boiler feed water system and components. The corrosion will produce ferric oxide, which enters the boiler, sediment or adhere 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. In severe cases of pipe corrosion, even pipe accidents may occur. 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 of 100°C or higher95℃All of our hot water boilers are deaerated. For many years, numerous boiler water treatments 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.JSNCYType Series Integrated Deaerator(Also known as the new type of internal oxygen scavenger and internal spray type oxygen scavenger)Utilizing advanced design and manufacturing techniques, our deaerators offer numerous advantages over conventional industry standards. Currently, several domestic companies, both established and under construction, have adopted our integrated deaerator technology, and all have achieved excellent operational results.
Two.Deoxygenator working principle
The deaerator generally includes two working processes.:
1.A single deoxygenation: Water not treated for oxygen is introduced through the inlet and flows into the deoxygenation pipe, where it is ejected through nozzles to form a mist. The mist falls through the liquid-vapor network and is thoroughly mixed with steam entering through the steam inlet, achieving the deoxygenation temperature. Most of the oxygen in the water is then extracted and released through the exhaust outlet, completing the first stage of deoxygenation.
2.Deaeration Stage 2: 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 outlet at the bottom, causing any oxygen not removed in the first stage to fully precipitate, significantly reducing the oxygen content in the water. At this point, the second deaeration is complete.
Three.Integrated oxygen removal unit structure
JSNCYThe Type Series Integrated Deaerator is composed of a steam-water mixture heater, tank, soft water inlet coil, secondary heating and red boiling tube, insulation board, anti-cavitation device, level gauge, thermometer, automatic overflow tank, safety valve, and electric valve, as shown in the figure.
