Low-pressure thermal deaerator

Product Details

One.Foreword

DeaeratorBoilerOne of the key equipment for heating systems。

In the boiler feed water treatment process, deoxygenation is a critical step. Oxygen is a major corrosive substance in both the feed water system and the boiler. Oxygen in the feed water should be removed promptly, otherwise it will corrode the boiler feed water system and components. Corrosion produces ferric oxide, which enters the boiler, settling or adhering to the boiler tube walls and heating surfaces, forming difficult-to-dissolve iron scales that impair heat transfer. Moreover, corrosion can cause pitting on the inner walls of pipes, increasing the resistance coefficient. Severe pipe corrosion can even lead to pipeline accidents. The state regulations stipulate that the evaporation capacity is greater than or equal to2Steam boiler with a capacity of more than or equal to tons per hour and water temperature95℃All of our hot water boilers are deaerated. Over the 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.JSNCYIntegral Oxygen Remover Series Type(Also known as the new integrated oxygen scavenger or integrated spray-type oxygen scavenger)Utilizing cutting-edge design and manufacturing techniques, our oxygen removers offer numerous advantages over conventional industry standards. Currently, several domestic companies, both established and under construction, have adopted the integrated oxygen removal technology, with all operational enterprises achieving excellent performance results.

Two.Operating Principle

The deaerator generally includes two working processes.:

1.One-time Deaeration: Water not deaerated enters the deaeration pipeline through the inlet, and is ejected through nozzles, forming a mist. The mist falls through the liquid-vapor mesh and is thoroughly mixed with steam entering through the steam inlet, achieving the deaeration temperature. Most of the oxygen in the water is then released and expelled through the exhaust port, completing the one-time deaeration process.

2.Deaeration II: The purpose of secondary deaeration is to ensure that the tank's internal temperature is consistently maintained at the deaeration temperature to maximize the deaeration effect. This is achieved by heating the already deaerated water through the auxiliary heating port at the bottom, allowing the oxygen that was 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.Deoxygenator structure

JSNCYThe Type Series Integrated Oxygen Remover is composed of components such as the 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, and electric valve.
