❀ Structural principle
The deoxygenation equipment mainly consists of two major parts: the deoxygenation tower head and the deoxygenation water tank, as well as connecting pipes and external components. The main component of the deoxygenation device (deoxygenation tower head) is composed of a shell, a steam water separator, a new type of membrane separator (membrane tube), a water spray grate, and a thermal storage packing liquid vapor network Below, we will focus on introducing the structural principle of the deoxygenation tower head
1. Shell: It is made by welding the cylinder body and stamped elliptical head. The medium and small low-pressure deaerators are equipped with a pair of flanges connecting the upper and lower parts for assembly and maintenance, and the high-pressure deaerator is equipped with a manhole for maintenance.
2. Soda water separator: This device replaces the traditional grass hat cone structure design inside the deaerator, eliminating the phenomenon of steam carrying water in the deaerator.
3. Diaphragm unit: consisting of a water chamber, a steam chamber, a diaphragm tube, a condensate connection, a makeup water connection, and a primary steam inlet connection Condensed water, chemical makeup water, and water are sprayed out in a spiral shape at a certain angle through a membrane separator, forming a water film skirt, and exchanging heat with the heating steam introduced through the primary heating steam connection to form a primary deoxygenation. The feedwater is heated to a saturation temperature close to the working pressure of the deoxygenator, that is, 2-3 ℃ lower than the saturation temperature, and undergoes crude deoxygenation Generally, about 90-95% of the oxygen content in the feedwater can be removed through this membrane spinning section.
4. Dripping grate: It is made up of several layers of staggered angular steel, and the water that has been roughly deoxygenated by the rotating membrane section is distributed again here, falling uniformly in a rain like manner onto the liquid vapor grid installed below it.
5. Thermal storage filling liquid vapor network: It is composed of flat steel strips and a cylindrical body that are spaced apart from each other, and is equipped with a specially designed stainless steel wire mesh at a certain height. The feedwater is fully in contact with the secondary steam here, heated to saturation temperature and deeply deoxygenated. The low-pressure atmospheric deaerator is below 10ug/L, and the high-pressure deaerator is below 5ug/L (the departmental standards are 15ug/L and 7ug/L, respectively).
6. The deoxygenated water from the water tank is collected in the lower container of the deaerator, which is the water tank. The deoxygenated water tank is equipped with the latest scientifically designed strong heat exchange and reboiling device. This device has the advantages of strong heat exchange, rapid increase in water temperature, deeper deoxygenation, reduced water tank vibration, and reduced noise, which improves the service life of the equipment and ensures its safe and reliable operation.

❀ Equipment features
① High deoxygenation efficiency, with a 100% qualified rate of oxygen content in the feedwater. The oxygen content in the feed water of atmospheric deaerator should be less than 15 цɡ/L, and the oxygen content in the feed water of pressure deaerator should be less than 7 цɡ/L.
② Stable operation without vibration. Suitable for negative pressure start-up and sliding pressure operation, reducing the need for manual and complicated adjustment operations during start-up and operation.
③ In addition to its good adaptability and low requirements for water quality and temperature, it can also operate at a short-term output of about 50%.
④ Low exhaust volume and energy consumption.
