For most thermal equipment, the most important thing in the process of boiler feed water is to remove oxygen, because the dissolved oxygen in the water into the pipeline, not only the water pipeline and the corresponding thermal equipment will cause corrosion, also will be corrosion of the residue and other substances into the boiler.

 After a long period of time, the metal corrosion residue on the evaporating surface of the boiler continuously precipitates and increases the thickness of the inner wall of the heating surface of the boiler, which will not only affect the heating effect, but also cause the damage of the boiler tube. 

Therefore, in addition to oxygen treatment is mainly to prevent, or to reduce the thermal equipment of“Oxygen corrosion”, but in addition to dissolved oxygen, but also because of the thermal equipment in a different environment, into some other gases. For example, if the production environment of a power plant is different from that of a chemical plant, then the amount and probability of carbon dioxide and sulfur dioxide are different. The deaerator can be heated through the water regeneration system and the hydrophobic reclaimer, reducing this corrosion and ensuring that waste heat is utilized. It should be noted that deaerator is not any new technology or things, as early as the 50s and 60s of the last century, our country has begun to produce and put into the market. However, the early deaerator is relatively backward, most of them are water-sprinkling tray deaerator, the effect of deaerator is limited; in the development process, the design of the deaerator scientific, manufacturing quality has been improved, generally divided into two types, that is, physical deoxidization and chemical deoxidization device.

In the more than ten kinds of deaerators that have been put into production, the deoxidization depth and the target of reaching are basically the same, but the difference is adaptability and stability, for example, whether the deaerator can start under sliding pressure, whether the deaerator can run under sliding pressure, the adaptability to dissolved oxygen, water temperature and other parameters.

 After Comprehensive Evaluation, the data showed that the performance of the rotating membrane deaerator was better, whether in the aspects of water-spraying density, rising temperature, etc. , it is widely used in power system, petrochemical industry, metallurgy and other fields with good quality. 

At the same time, the rotary membrane deaerator and other types of deaerator, in the same environment, compared, showing a stable operation, thorough deoxygenation and other advantages. Lianyungang Jiusheng Electric Auxiliary Equipment Co. , Ltd. has more than 10 years of experience in the design and manufacture of deaerator, with efficient manufacturing system and mature design experience, compared with the same industry manufacturers have many advantages: high efficiency, long life, low energy consumption, more environmental protection, targeted design. The products of Jiusheng Company are exported to home and abroad, and we have received good customer feedback in the process of actual production.
