Description

Technical Field

[0001] The utility model relates to the field of water deoxygenation, in particular to a deoxygenation water tank for a heating system. Background Art

[0002] This new model refers to patent 201621461303.4, a thermal and chemical combined deoxygenation water tank, application date 20161229, and has been improved.

[0003] There is always a portion of oxygen dissolved in water that has not been deoxygenated. After the oxygen-containing water enters the heating system, the oxygen dissolved in the water will seriously corrode the metal of the heating system in a boiling state, thereby reducing the service life of the boiler. In order to extend the service life of the boiler, the feed water must be deoxygenated before entering the boiler. Chemical agents and thermal deoxygenation are generally used. Since chemical agents are prone to residue, thermal deoxygenation is often used. The feed water is heated to a boiling state by steam. The steam partial pressure above the water surface increases, the gas partial pressure decreases, and the oxygen dissolved in the water escapes, achieving the purpose of deoxygenation. This patent has some shortcomings when performing deoxygenation. When water is poured from the top of the water tank, the water droplets and steam can only contact a small area, and the heating effect is poor. When the heating system performs deoxygenation operation, the volume of liquid that needs to be deoxygenated at a time is too large, and the steam inlet ring pipe under the liquid in the water tank cannot achieve the heating effect in a short time, which takes too long. After the water boils, the steam carrying oxygen is directly discharged into the air without being recovered.

[0004] Therefore, improvements are made to the above problems, and a deoxygenated water tank for a heating system is obtained to solve the above problems. Utility Model Content
