Description

Technical Field

[0001] This utility model relates to the field of deaerator water outlet technology, and more specifically, to a multi-inlet low-resistance water outlet device with filtration function. Background Technology

[0002] Small and medium-sized steam boilers typically have thermal deaerators in their water supply systems. These deaerators use steam generated by the boiler itself to heat the boiler feedwater. They effectively remove dissolved oxygen and other gases from the boiler feedwater, preventing corrosion of thermal equipment and are crucial for ensuring the safe operation of power plants and industrial boilers. After being deoxygenated by steam heating in the deaerator head, the boiler feedwater falls into the deaerator tank, where it is further heated by reboiling tubes arranged within the tank.

[0003] In existing technologies, thermal deaerators are conventionally equipped with a single suction port water outlet device. Due to the limited inlet cross-section of a single suction port, adding a filter component can easily cause problems such as high resistance and difficulty in water intake. At the same time, the installation position of the single suction port water outlet device needs to be far away from the deaerator head water drop point to improve the secondary steam heating effect of the reboiling tube and avoid short circuit in the water system. Therefore, the conventionally designed single suction port water outlet device has certain limitations in terms of both functionality and installation position. Therefore, we have made improvements and proposed a multi-suction port low-resistance water outlet device with filtration function. Utility Model Content
