Abstract

This invention belongs to the field of deaerator technology, and in particular to a boiler soft water thermal deaerator, including a deaeration mechanism and a water storage tank. The deaeration mechanism includes a deaeration tank body, with impurity removal mechanisms symmetrically fixed on both sides of the deaeration tank body. A steam-water separator is fixedly installed at the upper end of the deaeration tank body to separate steam and water generated during the deaeration process. The multi-stage swirl and liquid-gas partition design: through the multi-stage swirl tube and liquid-gas partition structure, water and steam are fully mixed and swirled within the swirl tubes, greatly increasing the contact area and contact time between water and steam, accelerating the precipitation of dissolved oxygen in the water, and significantly improving deaeration efficiency. The two-stage packing structure, with an upper liquid-gas mesh packing layer and a lower liquid-gas mesh packing layer inside the deaeration tank body, further enhances the gas-liquid contact effect, making the deaeration process more thorough and ensuring that the dissolved oxygen content in the deaerated water meets the strict standards for boiler water.
