Electrode boiler deaerator

Technical Field

The utility model relates to a deoxidization equipment manufacturing technology especially relates to an electrode boiler deoxidization device, belongs to boiler auxiliary device and makes technical field.

Background

In the process of boiler feed water treatment, oxygen removal is a very critical link. Oxygen is a main corrosive substance of a water supply system and a boiler, and the oxygen in the water supply should be quickly removed, otherwise, the oxygen can corrode the water supply system and parts of the boiler, iron oxide generated by corrosion can enter the boiler and deposit or attach on the pipe wall and the heated surface of the boiler to form an indissolvable channel to iron scale with poor heat transfer, and the corrosion can cause pitting on the inner wall of the pipeline, so that the resistance coefficient is increased. When the pipeline is seriously corroded, even pipeline explosion accidents can happen. The traditional process of oxygen removal is thermal oxygen removal, and the thermal oxygen removal is also a wider oxygen removal method with better oxygen removal effect, namely softened water is heated to 104 ℃, and oxygen in water can be completely discharged from the water.

In the prior art, boiler feed water is generally heated to a saturation temperature under the pressure (0.018 MPa) of an atmospheric thermal deaerator by using steam, the steam pressure on the surface of the water is close to the full pressure of the water surface, the partial pressure of various gases dissolved in the water is close to zero, the feed water does not have the capacity of dissolving the gases, and the gases dissolved in the water are separated out, so that the aims of removing oxygen and protecting thermal equipment and pipelines are fulfilled. However, such oxygen removal efficiency is slow, and long-time heating is required, resulting in low oxygen removal efficiency.
