Description

Technical Field

[0001] This utility model relates to the technical field of water deaerator equipment, specifically to a deaerator head mechanism for a thermal deaerator. Background Technology

[0002] A thermal deaerator is a device that uses hydrothermal properties to remove oxygen from water, ensuring the quality of the water supply and preventing dissolved oxygen from corroding water pipes, economizers, and other auxiliary equipment that come into contact with water, causing equipment failure and water pollution. It is widely used in power system boilers, industrial boiler feedwater, and thermal power plant makeup water. The deaerator head is the main deaeration mechanism of a thermal deaerator.

[0003] According to the patent application CN113375147B, which describes a deaerator head mechanism for a thermal deaerator, the present invention relates to the field of water deaerator equipment and discloses a deaerator head mechanism for a thermal deaerator, including a housing, a cover on the top of the housing, and an exhaust port on the top of the cover. The top and bottom of the inner cavity of the housing are respectively provided with a lower sealing plate and an upper sealing plate. An outer pipe and a heat exchange guide pipe are provided between the lower and upper sealing plates. The pipe is located inside the outer tube body. Through the structural design of the outer tube body and heat exchange guide pipe in the middle of the inner cavity of the box, the water to be deoxygenated is introduced from bottom to top through the heat exchange guide pipe, and the water vapor is introduced from top to bottom through the outer tube body. The water vapor entering the box body for deoxygenation is used to preheat the hot water in the heat exchange guide pipe, which compensates for the heat loss during the process of the heated water entering the box body. This ensures that the temperature of the water to be deoxygenated and the water vapor are kept at a high level when they come into contact with each other on the outside of the outer tube body for deoxygenation, thereby improving the deoxygenation effect and efficiency.

[0004] Regarding the above description, the applicant believes the following issues exist:

[0005] During operation, the device continuously introduces heated water to be deoxygenated into the tank through a water injection pipe, while simultaneously introducing steam through a steam injection pipe. The hot water to be deoxygenated flows through the interior of the heat exchange guide pipe, overflows from the upper sealing plate at the top of the heat exchange guide pipe, and flows through the middle channel to the inner guide ring plate outside the outer pipe. In actual use, because the water flow is transmitted through a fixed water channel, the internal water flow cannot effectively contact the hot steam for deoxygenation, thus affecting the deoxygenation effect. Furthermore, the device directly exhausts gas, which can easily lead to contamination of the exhaust duct by external gases or impurities. Therefore, it is necessary to improve the deoxygenation head mechanism of a thermal deaerator to solve the above problems. Utility Model Content

[0027] Example 1:

[0028] Addressing the problem in existing technologies where water flow is transported via fixed channels, resulting in insufficient contact between the internal water flow and hot steam for deoxygenation and thus affecting deoxygenation efficiency, this embodiment provides a deoxygenation head mechanism for a thermal deaerator. Please refer to [link / reference needed]. Figures 1-4 This utility model provides a technical solution: a deaerator head mechanism for a thermal deaerator, including a deaerator box 1, a water vapor separator 2 fixedly connected to the top of the deaerator box 1, a water inlet pipe 3 fixedly connected to the left side of the deaerator box 1, a drain pipe 4 fixedly connected to the right side of the deaerator box 1, a support leg 5 fixedly connected to the bottom of the deaerator box 1, a movable deaerator mechanism 6 provided inside the deaerator box 1, and an auxiliary exhaust mechanism 7 provided on the top of the water vapor separator 2;

[0029] The movable deoxygenation mechanism 6 includes a movable component 61 and a deoxygenation component 62. The movable component 61 is located inside the deoxygenation chamber 1, and the deoxygenation component 62 is located at the bottom of the deoxygenation chamber 1.

[0030] Furthermore, the active component 61 includes a motor 611, which is fixedly connected to the left side of the deaerator 1. The output end of the motor 611 extends through the deaerator 1 and is fixedly connected to a connecting plate 612 inside. A stirring frame 613 is fixedly connected to the right side of the connecting plate 612. A stirring blade 614 is rotatably connected inside the connecting plate 612. A first gear 615 is fixedly connected to the left side of the stirring blade 614. The connection plate 612 is fixedly connected inside the deaerator 1, which facilitates the stirring blade 614 to rotate on its own axis while following the connecting plate 612 to revolve around the central axis, thereby fully agitating the water to be deaerated entering the deaerator 1 and meeting the subsequent deaeration effect.

[0031] Furthermore, the first gear 615 meshes with the first toothed plate 616, and two stirring blades 614 are provided, with the two stirring blades 614 symmetrically distributed about the center line on the right side of the deaerator 1, which facilitates a more stable stirring process.

[0032] Furthermore, the deoxygenation assembly 62 includes a jet pipe 621, which is rotatably connected inside the deoxygenation chamber 1. A second gear 622 is fixedly connected to the outside of the jet pipe 621, and an air inlet pipe 623 is fixedly connected to the bottom of the jet pipe 621. A guide rail 624 is fixedly connected to the bottom of the deoxygenation chamber 1, and an electric telescopic rod 625 is fixedly connected to the bottom of the guide rail 624. A connecting block 626 is fixedly connected to the left side of the electric telescopic rod 625, and a second toothed plate 627 is fixedly connected to the top of the connecting block 626, which facilitates the adjustment of the rotation angle of the jet pipe 621, thereby ensuring sufficient jet treatment of the deoxygenated water inside the deoxygenation chamber 1.

[0033] Furthermore, the second toothed plate 627 meshes with the second gear 622, and the guide rail 624 has a groove at the corresponding position of the second toothed plate 627, and the second toothed plate 627 is slidably connected inside the groove, which facilitates a more stable deoxygenation process.

[0034] Example 2:

[0035] Based on Embodiment 1, the existing technology of direct exhaust leads to the easy contamination of the exhaust duct by external gases or impurities. Therefore, this utility model provides Embodiment 2 to solve the above-mentioned technical problems. Please refer to Embodiment 2. Figure 5Furthermore, in conjunction with Embodiment 1, the auxiliary exhaust mechanism 7 includes an exhaust pipe 71, which is fixedly connected to the top of the water vapor separator 2. A first fixing ring 72 is fixedly connected inside the exhaust pipe 71, a spring 73 is fixedly connected to the bottom of the first fixing ring 72, a sealing block 74 is fixedly connected to the bottom of the spring 73, and a second fixing ring 75 is fixedly connected inside the exhaust pipe 71. This facilitates the adjustment of the position of the sealing block 74, thereby meeting the requirement of following the changes in the internal air pressure of the deaerator 1 and realizing the discharge of the gas inside the deaerator 1.

[0036] Furthermore, the sealing block 74 contacts the second fixing ring 75, and the exhaust pipe 71 has a groove at the corresponding position of the sealing block 74, and the sealing block 74 is slidably connected inside the groove, which facilitates a more stable exhaust process.

[0037] In actual operation, when this device is used, the operator first connects the water inlet pipe 3 and the air inlet pipe 623 to the external deoxygenated water and hot steam inlet equipment, respectively. The motor 611 operates, causing the connecting plate 612 to rotate, which in turn moves the stirring blade 614 against the stirring frame 613. This, in conjunction with the first toothed plate 616, causes the first gear 615 to rotate, resulting in the stirring blade 614 rotating inside the connecting plate 612. The steam further heats the water to the saturation temperature under the pressure inside the deoxygenation head. At this point, the air pressure of other gases above the water surface is relatively low, causing the dissolved oxygen in the water to escape and rise with the steam. The water vapor is discharged through the electric telescopic rod 625, which works in conjunction with the connecting block 626 to make the second toothed plate 627 slide inside the guide rail 624. In conjunction with the second gear 622, the jet pipe 621 rotates inside the deaerator 1, thereby adjusting the rotation angle of the jet pipe 621. The outer surface of the jet pipe 621 has multiple air outlet grooves and is equipped with a one-way valve. Through the operation of the water vapor separator 2, the gas is released. The change in air pressure inside the deaerator 1 causes the sealing block 74 to move. The movement of the sealing block 74, in conjunction with the spring 73, realizes the discharge of gas inside the deaerator 1.
