[0002] Deaerators are key equipment in boilers and heating systems, used to remove dissolved oxygen and other non-condensable gases from boiler feedwater to prevent metal corrosion and reduced thermal system efficiency. Deaerators require nozzles to evenly distribute steam and water to maximize heat exchange efficiency. The design of these nozzles is crucial, affecting not only deaeration efficiency but also energy consumption and operational stability. In existing technologies, deaerator nozzles are directly fixed to the bottom of the water supply pipe. During operation, the direction and angle of water and steam flow are relatively fixed, resulting in poor mixing of water and steam, affecting deaeration and heat exchange efficiency, and leading to higher energy consumption.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0017] In the existing technology, the nozzles used for deaerators are directly fixed to the bottom of the water supply pipe. During use, the direction and angle of water and steam are relatively fixed, resulting in an unsatisfactory mixing effect between water and steam, which affects the deaeration efficiency and heat exchange effect, and also leads to high energy consumption of the equipment.
[0018] In view of this, the present invention provides a nozzle for a deaerator. Through the cooperation between the fixed base, bearing, rotating tube, connecting rod, fan blade, conical mouth, inner hole, connecting tube and conical nozzle, when high-pressure water is delivered to the nozzle of the deaerator, the rotating tube drives the connecting tube and conical nozzle to rotate, so that the high-pressure water is atomized into fine water droplets or water mist and sprayed out. The direction and angle of the spray are constantly changing, so that the mixing of water and steam in the deaerator is more uniform, thereby improving the deaerator's deoxygenation efficiency and heat exchange effect, and reducing energy consumption in the deaeration process.
[0019] Those skilled in the art should connect all electrical components and their compatible power supplies in this case via wires. Appropriate controllers and encoders should be selected according to the actual situation to meet control requirements. The specific connection and control sequence should refer to the working principle described below, where the electrical components are connected in sequence. The detailed connection methods are well-known in the art. The following mainly introduces the working principle and process, and will not describe the electrical control further.
[0020] Depend on Figure 1-4 It is known that a nozzle for a deaerator includes a fixed base 1, a bearing 2 fixedly connected to the inner wall of the fixed base 1, a rotating tube 3 fixedly connected to the inner wall of the bearing 2, a connecting rod 4 fixedly connected to the top of the rotating tube 3, fan blades 5 fixedly connected at equal intervals to the top of the connecting rod 4, a conical opening 6 provided at the top of the inner wall of the rotating tube 3, an inner hole 7 provided at equal intervals on the outer side of the rotating tube 3 located on the connecting rod 4, the two ends of the inner hole 7 being connected to the conical opening 6 and the bottom end of the rotating tube 3 respectively, a connecting tube 8 threadedly connected to the inner wall of the bottom end of the rotating tube 3, and a conical nozzle 9 provided at equal intervals on the outer wall of the bottom end of the connecting tube 8, the conical nozzle 9 being connected to the bottom end of the rotating tube 3;
[0021] In the specific implementation process, it is worth noting that, through the cooperation between the fixed seat 1, bearing 2, rotating tube 3, connecting rod 4, and fan blade 5, the fixed seat 1 is connected to the water supply pipe of the deaerator. When water is delivered into the fixed seat 1, it drives the fan blade 5 to rotate, which in turn drives the connecting rod 4 and rotating tube 3 to rotate synchronously. During the water delivery process, the rotating tube 3 is rotated. Through the cooperation between the fixed seat 1, rotating tube 3, conical inlet 6, inner hole 7, connecting pipe 8, and conical nozzle 9, the water flows through the bottom end of the fixed seat 1 into the conical inlet 6, and through the inner hole 7 to the bottom end of the rotating tube 3, and then through the conical nozzle 9 of the connecting pipe 8. High-pressure water is atomized into fine droplets or mist and sprayed out, increasing the contact area between water and steam and accelerating the precipitation of oxygen from the water. Through the cooperation between the fixed seat 1, bearing 2, rotating pipe 3, connecting rod 4, fan blade 5, cone 6, inner hole 7, connecting pipe 8 and conical nozzle 9, when the high-pressure water is delivered to the nozzle of the deaerator, the rotating pipe 3 drives the connecting pipe 8 and conical nozzle 9 to rotate, so that the high-pressure water is atomized into fine droplets or mist and sprayed out. The direction and angle of the spray are constantly changing, making the mixing of water and steam in the deaerator more uniform, thereby improving the deaerator's deoxygenation efficiency and heat exchange effect, and reducing energy consumption in the deaeration process.
[0022] Furthermore, the outer wall of the connecting pipe 8 is provided with a first limiting edge 10, and a sealing gasket 11 is connected to the top of the first limiting edge 10. The sealing gasket 11 is connected to the rotating pipe 3. A fixing sleeve 12 is threaded to the outer wall of the bottom end of the rotating pipe 3. A second limiting edge 13 is provided at the bottom end of the fixing sleeve 12. The second limiting edge 13 is connected to the connecting pipe 8.
[0023] In the specific implementation process, it is worth noting that through the cooperation between the connecting pipe 8, the first limiting edge 10, the sealing gasket 11, the fixed sleeve 12 and the second limiting edge 13, by inserting the fixed sleeve 12 into the outside of the connecting pipe 8 and rotating and fixing the fixed sleeve 12 with the rotating pipe 3, and limiting the first limiting edge 10 by the second limiting edge 13, the connection between the connecting pipe 8 and the rotating pipe 3 is made more stable, and the sealing between the connecting pipe 8 and the rotating pipe 3 is improved, avoiding leakage of water and steam, ensuring that the nozzle can maintain a stable working state under the action of high pressure water and steam, and improving the structural stability of the nozzle in the deaerator;

[0025] In the specific implementation process, it is worth noting that through the cooperation between the connecting pipe 8, the constriction port 14, the vertical rod 15 and the conical rod 16, a narrow tube structure is formed inside the connecting pipe 8, which increases the flow rate of water and steam in the connecting pipe 8, effectively prevents the water and steam from generating eddies inside the connecting pipe 8, and ensures that the water and steam can be evenly delivered to the conical nozzle 9, further improving the mixing effect of water and steam.
[0026] Furthermore, a third limiting edge 17 is provided on the inner wall of the rotating tube 3 above the connecting tube 8, and a filter screen 18 is connected to the bottom of the third limiting edge 17 inside the rotating tube 3. The filter screen 18 is connected to the connecting tube 8.
[0027] In the specific implementation process, it is worth noting that through the cooperation between the rotating tube 3, the connecting tube 8, the third limiting edge 17 and the filter screen 18, after the connecting tube 8 is screwed into the rotating tube 3, the top end of the connecting tube 8 and the third limiting edge 17 clamp and fix the filter screen 18, so that the filter screen 18 remains stable in the rotating tube 3 and is not easy to shake or fall off. This ensures that the water flow and steam can be effectively filtered and purified when passing through the filter screen 18, and avoids impurities from entering the deaerator or causing the nozzle to be blocked.
[0028] Furthermore, a connecting flange 19 is fixedly connected to the top of the mounting base 1. The connecting flange 19 is used for the connection between the nozzle and the water supply pipe to ensure the stability and convenience of nozzle installation.
[0029] In the specific implementation process, it is worth noting that the connecting flange 19 is used for the connection between the nozzle and the water supply pipe to ensure the stability and convenience of nozzle installation.
