Low-pressure deaerator

Product Details

One.Preface

DeaeratorBoilerOne of the key equipment for the heating system。

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. The 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 ferric oxide, which can enter the boiler, settle or adhere to the boiler tube walls and heating surfaces, forming difficult-to-dissolve iron scales that lead to poor heat transfer. Moreover, corrosion can cause pitting on the inner walls of the pipes, increasing the resistance coefficient. In severe cases of pipe corrosion, pipeline accidents may occur. 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 our hot water boilers are deoxygenated. Over the years, many boiler water treatment systems have been seeking a cost-effective deoxygenation method for constant temperature water. Lianyungang Jiu Sheng Electric Power Auxiliary Machinery Co., Ltd. has years of experience in designing and manufacturing deoxygenators.JSNCYIntegrated Type Series Oxygen Remover(Also known as the new type of built-in oxygen scavenger, built-in spray-type oxygen scavenger)Utilizing state-of-the-art design and manufacturing techniques, our deaerator offers numerous advantages over conventional industry models. Currently, several domestic companies, both established and under construction, have adopted our internal deaerator technology, with all operational units achieving excellent performance results.

The deaerator generally includes two working processes.:

1.A single oxygen removal: Water that has not been deoxygenated enters the deoxygenation pipeline through the inlet, and is then ejected through nozzles to form a mist. The mist falls through the liquid-vapor mesh and thoroughly mixes with the steam entering through the steam inlet, achieving the deoxygenation temperature. Most of the oxygen in the water is then extracted and expelled through the exhaust port, completing the first stage of deoxygenation.

2.Deaeration Stage Two: 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 port at the bottom, causing any oxygen not removed during the first stage to fully precipitate out, significantly reducing the oxygen content in the water. At this point, the second deaeration is complete.

Three.Deoxygenator structure

JSNCYThe Type Series Internal Deaerator is composed of components such as a steam-water mixture heater, tank, soft water inlet pipe, secondary heating and reboiling tube, thermal insulation board, anti-erosion device, level gauge, thermometer, automatic overflow tank, safety valve, and electric valve.
