As the operation of the deaerator increases, problems such as unqualified dissolved oxygen, increased exhaust steam volume, and increased energy consumption are discovered during the use of the deaerator. Our company's professional team handles difficult issues with deaerators!

Rotating film deaerator (patent number ZL 2010 2 0265898.2) is mainly aimed at the problems of poor load adaptability, easy vibration, excessive dissolved oxygen in deaerator, steam entrainment, high heat consumption, poor actual deaerating effect and high maintenance cost of the old deaerator, such as water sprinkling pan type and spray packing type. It is proposed to apply the new rotating film deaerator technology to reform the deaerator head of the old deaerator. Practice has proven that the rotary film deaerator has achieved the goals of energy conservation, reduced consumption, improved deaeration efficiency, increased stability, and reduced maintenance costs, and has good promotion and use value.

Deoxygenation is a crucial step in the boiler feedwater treatment process. Oxygen is the main corrosive substance in the water supply system and boiler. The oxygen in the water supply should be quickly removed, otherwise it will corrode the water supply system and components of the boiler. The corrosion product, iron oxide, will enter the boiler and deposit or adhere to the boiler tube wall and heating surface, forming insoluble and poorly heat transferred iron scale. Moreover, corrosion will cause pitting on the inner wall of the pipeline and increase the resistance coefficient. When pipeline corrosion is severe, pipeline explosion accidents may even occur. According to national regulations, steam boilers with an evaporation capacity of 2 tons per hour or more and hot water boilers with a water temperature of 95 ℃ or more must be deoxygenated. For many years, many boiler feedwater treatment workers have been exploring efficient and economical deoxygenation methods, and vacuum deoxygenation method is one of the excellent ones.

The CY series room temperature sponge iron deaerator uses highly active sponge iron deaerator to remove dissolved oxygen from water. After treatment, the dissolved oxygen content in the water can be reduced to below 0.05mg/L. It can be widely used for anti-corrosion of boiler feedwater and industrial circulating water facilities, and is an ideal environmentally friendly deaeration equipment.

The deaerator mainly aims at the problems of poor load adaptability, easy vibration, excessive dissolved oxygen in the deaerator, high heat consumption, poor actual deaerating effect and high maintenance cost of the water spray tray type, spray packing type and old thermal deaerator. It is proposed to apply the new thermal deaerator technology to reform the deaerator head of the original spray packing deaerator. Practice has proven that the thermal deaerator has achieved the goals of energy conservation, reduced consumption, improved deaeration efficiency, increased stability, and reduced maintenance costs, and has good value for promotion and use.

The operation of a thermal deaerator requires steam to heat the feedwater to saturation, reducing the surface tension difference of water to discharge oxygen and other gases, which consumes a considerable amount of heat. Steam in cogeneration projects is more economical compared to electricity generation.

In order to achieve better separation efficiency and mixed heating capacity, in recent years, Lianyungang Huaneng Power Auxiliary Equipment Co., Ltd. has developed various types of regular fillers composed of various materials such as metal wire mesh, plate mesh, orifice plate, and rolled piercing hole, based on the development characteristics of fillers at home and abroad, as well as various equipment usage conditions. Its basic characteristics are simple structure, pressure reduction, high flux, and high separation efficiency, which are widely used in distillation, absorption, extraction and other processes.
