One.Preface

The deaerator is a special type of low-pressure thermal deaerator.

In the boiler feed water treatment process, deoxygenation is a critical step. Oxygen is the 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's feed water system and components. The corrosion will produce iron oxide that enters the boiler, settle or adhere to the boiler tube walls and heating surfaces, forming difficult-to-dissolve iron 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 pipe accidents. The national 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 deoxygenated. Over the years, many boiler water treatments have been seeking a cost-effective deoxygenation method for ambient water. Lianyungang Jiusheng Power Auxiliary Equipment Co., Ltd. has years of experience in designing and manufacturing deoxygenators.JSNCYIn-built Oxygen Remover Series(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, and all have achieved excellent 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, is ejected through nozzles to form a mist, which then falls and passes through a liquid-vapor grid. It is thoroughly mixed with steam entering through the steam inlet, reaching the deoxygenation temperature. Most of the oxygen in the water is then extracted 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 temperature consistently at the deaeration temperature, ensuring maximum deaeration efficiency. This process is achieved by heating the already deaerated water through auxiliary heating ports at the bottom, causing any oxygen that was not precipitated during the first deaeration to fully separate, 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 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, and electric valve, as shown in the figure.
