Description

Technical Field

[0001] The utility model relates to the technical field of deaerators, in particular to an exhaust steam receiver for a deaerator. Background Art

[0002] According to the requirements of coal chemical industry and power generation process, the feed water must be deoxygenated before entering the boiler to reduce the corrosion caused by oxygen in the feed water to the boiler. At present, the thermal deoxygenation method widely used in boiler feed water deoxygenation in power plants must be emptied of oxygen and uncondensed steam in the deaerator at any time to ensure the deoxygenation effect. Since the existing deaerator only has an exhaust pipe and no steam recovery device, the discharge of a large amount of steam causes a waste of energy and water resources and reduces the efficiency of the system. At the same time, the steam contains more impurities, which leads to pipeline blockage or equipment failure during the recovery process, which will affect the recovery effect. For example, a Chinese patent discloses "a A deaerator exhaust steam receiver", whose application number is: "202321045604.9", can use the water-steam dual-purpose pump to extract air when no water enters the collection box through the combination of a rotary joint and a water-gas dual-purpose pump. Since the rotary tube is connected to the condensation shell, the water-steam dual-purpose pump can quickly draw external steam in through the rotary tube and the condensation shell, so that the steam quickly contacts the condensing agent in the condensation shell for condensation, thereby improving the efficiency of steam condensation. However, the equipment has no impurity removal measures, which may cause pipeline blockage or equipment failure during the recovery process, affecting the recovery effect. Utility Model Content
