Description

Technical Field

[0001] The utility model belongs to the technical field of deaerators, and in particular relates to a tower-less deaerator. Background Art

[0002] The deaerator is a hybrid heater that works on the principle of thermal deoxygenation. It can not only analyze and remove dissolved gases in the feed water, but also store a certain amount of feed water, alleviate the flow imbalance between condensate and feed water, and use heat recovery extraction steam to heat the feed water, thereby improving the thermal efficiency of the unit. When designing the thermal system, the deaerator is also used to recover high-quality drain and gate rod leakage steam.

[0003] The towerless deaerator is mainly composed of a head, a cylinder, a support and internal components. There is no deaerator tower, and the deaeration process is completed in the deaerator water tank. Water is sprayed into the deaerator space from the nozzle and then flows to the water outlet; the heating steam inlet pipe is arranged along the axial direction of the deaerator cylinder, and the heating steam is sent to the deaerator through the air pipe, mixed with water and heated water, and the dissolved oxygen and other non-condensable gases in the water are brought out of the water surface to achieve the purpose of deep deoxygenation of the water. Its specific working principle: the liquid that needs to be deoxygenated will be atomized through a high-pressure nozzle and injected into the water storage cylinder. At this time, high-temperature steam will be discharged from the inside of the water storage cylinder to deoxygenate the atomized liquid. In this process, oxygen and other non-condensable gases will be discharged from the pipe at the top of the water storage cylinder, and the atomized liquid will gradually condense and be discharged through the pipe at the bottom of the water storage cylinder. Using this method, the liquid can only undergo a deoxygenation process once, and it is difficult to deoxygenate twice or even multiple times. For this reason, a towerless deaerator is provided.
