Abstract

The invention provides a boiler feed water deaerator and a boiler system. A certain volume of shielding gas is injected into a dosing tank through a gas filling unit by means of the boiler feed water deaerator. Due to the fact that the density of the shielding gas is larger than that of oxygen, the shielding gas can float on the surface of liquid in the dosing tank, and the air is isolated from the liquid surface; and due to the fact that it is difficult for the shielding gas to react with an oxygen scavenger, the oxygen in the air is isolated from a solution through the shielding gas, the oxygen scavenger in the solution cannot be in contact with the oxygen in the air, oxidation is prevented, the increase speed of the amount of salt in a deoxygenization water tank is reduced, and accordingly the waste of heat and water resources is reduced.

Description

technical field [0001] The invention relates to the technical field of boiler systems, in particular to a boiler feed water deoxygenation device and a boiler system for deoxidizing boiler feed water by adding chemicals. Background technique [0002] A variety of gases are dissolved in the boiler feed water, and some gas components will affect the service life of the boiler equipment. Among these gases, oxygen has the greatest impact on the boiler equipment, which seriously affects the service life of the boiler. In order to remove these oxygen, usually in Sulfite (usually sodium sulfite) is added to the boiler feed water to remove oxygen dissolved in the boiler feed water and protect the feed water pipes and the inner wall of the boiler from oxygen corrosion. Adopting this method, the cost is low, the equipment is simple, the operation is convenient, and the deoxygenation effect is good. [0003] In actual use, sulfite is usually dissolved in water to form a sulfite aqueous...
