Description

Technical Field

[0001] This utility model relates to a deoxygenation device, specifically, to a highly efficient deoxygenation device. Background Technology

[0002] The deoxygenated water required during the operation of dry quenching waste heat boilers is obtained through thermal and chemical deoxygenation. Thermal deaerators are designed with a heating steam pressure of 0.2 MPa. However, in practice, the low-pressure steam index used in different plants is not consistent, resulting in poor deoxygenation when using low-pressure steam for heating and deoxygenation. This fails to meet the dissolved oxygen requirement of less than 7 μg / L for high-temperature, high-pressure waste heat boilers. Furthermore, if the low-pressure steam pressure is too high, excessive condensate from the deaerator exhaust port can spray onto the ground, posing a safety hazard.

[0003] Therefore, there is an urgent need for a highly efficient deoxygenation device that can adapt to different low-pressure steam, effectively utilize low-pressure steam, and ensure that dissolved oxygen meets the required standards; the amount of condensate at the deaerator exhaust port should be significantly reduced to avoid personal injury accidents and protect the safety of workers.
