Description

Technical Field

[0001] The present invention relates to the technical field of deaerator water distribution, and particularly to a thermal deaerator. Background Art

[0002] Deaerators are classified into pressure deaerators and atmospheric deaerators according to pressure. Atmospheric deaerators are also called low-pressure deaerators. Thermal deaerators use heating steam to remove oxygen. As we know, according to the dissolution characteristics of gases in water, to remove any gas in water, it is only necessary to remove the gas existing on the water surface. Therefore, to remove various gases in water, it is best that there is only water vapor on the water surface without other gases. A thermal deaerator heats water to the boiling point, reduces the solubility of oxygen and makes it escape, and then removes the oxygen generated on the water surface to make it filled with steam. In this way, oxygen in water continuously escapes, ensuring that the oxygen content of the feed water meets the feed water quality standard.

[0003] During the deaeration process of water, due to the increase in water temperature, bubbles are generated. The appearance of too many bubbles will accumulate inside the equipment, form a foam layer, hinder the flow of water, affect the uniformity during water spraying, and hinder the deaeration process. Summary of the Invention

[0004] To solve the above technical problems, the present invention provides a thermal deaerator, including a defoaming component, and the defoaming component further includes a deaeration tank fixedly connected thereto. The surface of the deaeration tank is fixedly connected with a deaerated water tower, and the bottom of the deaerated water tower is fixedly connected with a drain pipe;

[0005] A drainage component, and the drainage component further includes a sliding orifice plate slidably connected to the inner wall of the deaerated water tower. The surface of the sliding orifice plate is fixedly connected with a guide plate, and the surface of the sliding orifice plate is fixedly connected with a U-shaped sliding plate.

[0006] A residence component, and the residence component further includes a restoring spring fixedly connected to the inner wall of the deaerated water tower. One end of the restoring spring away from the deaerated water tower is fixedly connected with a T-shaped slider.

[0007] Preferably, the defoaming component further includes a water inlet pipe fixedly connected to the surface of the deaerated water tower. A water pump is fixedly connected to the bottom of the water inlet pipe. A water tank is arranged directly below the water pump, and a servo motor is fixedly connected to the surface of the deaerated water tower.

[0008] Preferably, the defoaming component further includes a rotating long rod fixedly connected to the end of the servo motor. A fixed hole plate is fixedly connected to the surface of the rotating long rod. One end of the fixed hole plate away from the rotating long rod is slidably connected to a telescopic cleaning plate. A compression spring is fixedly connected to the surface of the telescopic cleaning plate. One end of the compression spring away from the telescopic cleaning plate is fixedly connected to the inner wall of the fixed hole plate. During the rotation of the rotating long rod, the rotating long rod drives the cleaning plate to rotate together. The cleaning plate at the far end and the telescopic cleaning plate will be squeezed at different positions on the inner wall. During this process, the inner wall will be cleaned, and the water droplets on the inner wall will be scraped. During this process, the scraped water droplets will flow downward along the ends of the telescopic cleaning plate and the cleaning plate. During this process, the small water droplets generated after treating the bubbles are cleaned, preventing oxygen from redissolving into the small water droplets and affecting the deoxygenation efficiency. For the flowing water, it is prevented that the small water droplets form a water film, resulting in a cleaning dead zone and affecting the overall flow uniformity and gas-liquid contact effect.

[0009] Preferably, the defoaming component further includes a rotating cylindrical rod rotatably connected to the inner wall of the deaeration water tower. A cleaning plate is fixedly connected to the surface of the rotating cylindrical rod. A compression spring is fixedly connected to the inner wall of the cleaning plate. A fixed short rod is fixedly connected to the surface of the cleaning plate. A pointed column is fixedly connected to the surface of the fixed short rod.

[0010] Preferably, the defoaming component further includes a fixed rod fixedly connected to the surface of the cleaning plate. A rotating block is rotatably connected to the surface of the fixed rod. A limiting block is fixedly connected to the surface of the cleaning plate. A limiting rod is fixedly connected to the surface of the fixed rod. When the servo motor is started, the rotating servo motor drives the rotating long rod to rotate. The cleaning plates on both sides of the rotating long rod will rotate under the action of the rotating long rod. During this process, pointed columns are arranged on the surfaces of the compression springs on both sides. During the rotation, the pointed columns will treat the bubbles generated when the water flow contacts the steam, facilitating their discharge. The holes arranged on the fixed hole plate reduce the influence on the water flow rate during the water flow process and improve the deoxygenation efficiency. Among the above components, the bubbles generated during the deaeration process of the flowing water are treated, preventing excessive bubbles from forming a foam layer, resulting in a reduction in water flow and an increase in system resistance.

[0011] Preferably, the drainage component further includes a tension spring fixedly connected to the surface of the U-shaped slide plate. One end of the tension spring away from the U-shaped slide plate is fixedly connected to the inner wall of the deaerating water tower. A fixed block is fixedly connected to the bottom of the U-shaped slide plate. At this time, the cleaning plate will squeeze the sliding orifice plate, and the sliding orifice plate will drive the U-shaped slide plate on its surface to slide on the inner wall of the deaerating water tower. When the cleaning plate moves away from the sliding orifice plate, the tension spring at the end of the U-shaped slide plate will recover, restoring the U-shaped slide plate, and thus restoring the sliding orifice plate. During this process, the sliding orifice plate will swing slightly, swinging the flowing water. Under the action of the guide plate, the water will flow evenly through the holes of the sliding orifice plate. During the process, the above components control the amount of flowing water, ensuring that the flowing water can flow evenly to each position, reducing the occurrence of dead zones, and improving the uniformity of the water flow.

[0012] Preferably, the residence component further includes a coil spring fixedly connected to the inner wall of the T-shaped slider. A fixed short cylinder is fixedly connected to the inner wall of the coil spring. One end of the fixed short cylinder away from the coil spring is fixedly connected to a rotating square block. A telescopic long column is fixedly connected to the inner wall of the deaerating water tower. A spring is fixedly connected to the inner wall of the telescopic long column. During the up and down sliding process of the U-shaped slide plate, the fixed block at the bottom of the U-shaped slide plate will squeeze the T-shaped slider. During this process, the T-shaped slider will drive the rotating square block to move forward, and the rotating square block will squeeze the rotating orifice plate. At this time, the rotating orifice plate will rotate. When the fixed block rises, the restoring spring on the inner wall of the deaerating water tower will pull the T-shaped slider back to its original position. At this time, the rotating square block will be squeezed and will rotate and recover under the action of the coil spring.

[0013] Preferably, the residence component further includes a support long rod fixedly connected to the inner wall of the deaerating water tower. A sliding short column is fixedly connected to the end of the support long rod. A rotating orifice plate is rotatably connected to the surface of the sliding short column. A hollow column is fixedly connected to the bottom of the rotating orifice plate. A ratchet is fixedly connected to the surface of the hollow column. During the up and down movement of the fixed block, the rotating square block will continuously push the rotating orifice plate, and the rotating orifice plate will continuously rotate. Among the above components, the rotating rotating orifice plate contacts the flowing water falling from the sliding orifice plate. During the rotation process, the flowing water will stay on the surface of the rotating orifice plate, enabling the flowing water to come into full contact with the steam for deaeration, and controlling the flow of the water.

[0014] The present invention has the following beneficial effects:

[0015] Start the servo motor. The rotating servo motor drives the rotating long rod to rotate. The cleaning plates on both sides of the rotating long rod will rotate under the action of the rotating long rod. During this process, there are pointed columns on the surface of the compression springs on both sides. During the rotation, the pointed columns will process the bubbles generated when the water flow contacts the steam, facilitating their discharge. The holes provided on the surface of the fixed orifice plate reduce the impact on the water flow rate during the water flow process, improving the deaeration efficiency. Among the above components, the bubbles generated during the water flow deaeration process are processed, preventing excessive bubbles from forming a foam layer, which would lead to a decrease in water flow and an increase in system resistance.

[0016] During the rotation of the rotating long rod, the rotating long rod drives the cleaning plates to rotate together. The cleaning plate at the far end and the telescopic cleaning plate will be squeezed at different positions on the inner wall. During this process, the inner wall will be cleaned, and the water droplets on the inner wall will be scraped. During this process, the scraped water droplets will flow downward along the ends of the telescopic cleaning plate and the cleaning plate. During this process, the small water droplets generated after processing the bubbles are cleaned, preventing oxygen from redissolving into the small water droplets and affecting the deaeration efficiency. The flowing water is processed to prevent the small water droplets from forming a water film, creating a cleaning dead zone and affecting the overall flow uniformity and gas-liquid contact effect.

[0017] During the rotation of the cleaning plate, there is a fixed rod on the surface of the cleaning plate. When the cleaning plate rotates to the bottom, the fixed rod prevents the connected rotating block from rotating downward under the action of gravity. The rotating block will rotate into the limiting block. At this time, the cleaning plate will be restricted and will not contract. At this time, the cleaning plate will squeeze the sliding orifice plate, and the sliding orifice plate will drive the U-shaped slide plate on its surface to slide on the inner wall of the deaeration water tower. When the cleaning plate moves away from the sliding orifice plate, the tension spring at the end of the U-shaped slide plate will recover, restoring the U-shaped slide plate, and thus restoring the sliding orifice plate. During this process, the sliding orifice plate will swing slightly, swinging the flowing water. Under the action of the guide plate, the water will flow evenly through the holes of the sliding orifice plate. During the process, the above components control the amount of flowing water, ensuring that the flowing water can flow evenly to each position, reducing the occurrence of dead zones, and improving the water flow uniformity.

[0018] During the up-and-down sliding of the U-shaped skateboard, the fixed block at the bottom of the U-shaped skateboard will squeeze the T-shaped slider. During this process, the T-shaped slider will drive the rotating square block to move forward, and the rotating square block will squeeze the rotating orifice plate. At this time, the rotating orifice plate will rotate. When the fixed block rises, the restoring spring on the inner wall of the deaerator tower will pull the T-shaped slider back to its original position. At this time, the rotating square block will be squeezed and will rotate and return under the action of the coil spring. During the up-and-down movement of the fixed block, the rotating square block will continuously push the rotating orifice plate, and the rotating orifice plate will continuously rotate. Among the above-mentioned components, the rotating orifice plate contacts the flowing water that falls on the sliding orifice plate. During the rotation process, the flowing water will stay on the surface of the rotating orifice plate, enabling the flowing water to come into full contact with the steam for deaeration, and controlling the flow of water.

During the rotation of the rotating long rod 107, the rotating rotating long rod 107 drives the cleaning plate 111 to rotate together. The cleaning plate 111 at the far end and the telescopic cleaning plate 109 will be squeezed at different positions on the inner wall. During this process, the inner wall will be cleaned, and the water droplets on the inner wall will be scraped. During this process, the scraped water droplets will flow downward along the ends of the telescopic cleaning plate 109 and the cleaning plate 111. During this process, the small water droplets generated after processing the bubbles are cleaned, preventing oxygen from redissolving into the small water droplets and affecting the deoxygenation efficiency.

The cleaning plates 111 on both sides of the rotating long rod 107 will rotate under the action of the rotating long rod 107. During this process, pointed columns 115 are arranged on the surfaces of the compression springs 112 on both sides.

In the above components, the bubbles generated during the deaeration process of the flowing water are processed, preventing excessive bubbles from forming a foam layer, resulting in a reduction in water flow and an increase in system resistance.

[0039] Example 2, please refer to Figure 5 - Figure 9, the present invention is a thermal deaerator. On the basis of Embodiment 1, the drainage component 2 further includes a tension spring 204 fixedly connected to the surface of the U-shaped slide plate 203. One end of the tension spring 204 away from the U-shaped slide plate 203 is fixedly connected to the inner wall of the deaerated water tower 102. A fixed block 205 is fixedly connected to the bottom of the U-shaped slide plate 203. At this time, the cleaning plate 111 will squeeze the sliding orifice plate 201, and the sliding orifice plate 201 will drive the U-shaped slide plate 203 on its surface to slide on the inner wall of the deaerated water tower 102. When the cleaning plate 111 moves away from the sliding orifice plate 201, the tension spring 204 at the end of the U-shaped slide plate 203 will be restored, restoring the U-shaped slide plate 203, and thus restoring the sliding orifice plate 201. During this process, the sliding orifice plate 201 will swing slightly, swinging the flowing water. Under the action of the guide plate 202, the water will flow evenly through the holes of the sliding orifice plate 201. During this process, the above components control the amount of flowing water, ensuring that the flowing water can flow evenly to each position, reducing the occurrence of dead zones, and improving the uniformity of the water flow.

[0040] The staying component 3 further includes a spiral spring 309 fixedly connected to the inner wall of the T-shaped slider 310. A fixed short cylinder 308 is fixedly connected to the inner wall of the spiral spring 309. One end of the fixed short cylinder 308 away from the spiral spring 309 is fixedly connected to a rotating square block 307. A telescopic long column 305 is fixedly connected to the inner wall of the deaerated water tower 102. A spring 306 is fixedly connected to the inner wall of the telescopic long column 305. During the process of the U-shaped slide plate 203 sliding up and down, the fixed block 205 at the bottom of the U-shaped slide plate 203 will squeeze the T-shaped slider 310. During this process, the T-shaped slider 310 will drive the rotating square block 307 to move forward, and the rotating square block 307 will squeeze the rotating orifice plate 301. At this time, the rotating orifice plate 301 will rotate. When the fixed block 205 rises, the restoring spring 311 on the inner wall of the deaerated water tower 102 will pull the T-shaped slider 310 back to its original position. At this time, the rotating square block 307 will be squeezed and will rotate and be restored under the action of the spiral spring 309.

[0041] The staying component 3 further includes a supporting long rod 32 fixedly connected to the inner wall of the deaerating water tower 102. The end of the supporting long rod 32 is fixedly connected with a sliding short column 302. The surface of the sliding short column 302 is rotatably connected with a rotating orifice plate 301. The bottom of the rotating orifice plate 301 is fixedly connected with a hollow column 303. The surface of the hollow column 303 is fixedly connected with a ratchet 304. During the up-and-down movement of the fixed block 205, the rotating square block 307 will continuously push the rotating orifice plate 301, and the rotating orifice plate 301 will continuously rotate. Among the above components, the rotating rotating orifice plate 301 contacts the flowing water falling from the sliding orifice plate 201. During the rotation, the flowing water will stay on the surface of the rotating orifice plate 301, enabling the flowing water to fully contact the steam for deaeration, thereby controlling the flow of water.

[0042] When using this device, place the device at the required position, start the water pump to introduce water flow into the deaerating water tower 102. At this time, then introduce high-temperature steam into the deaerating water tower 102. Next, start the servo motor 15. The rotating servo motor 15 will drive the rotating long rod 107 to rotate. The cleaning plates 111 on both sides of the rotating long rod 107 will rotate under the action of the rotating long rod 107. During this process, there are pointed columns 115 on the surface of the compression springs 112 on both sides. During the rotation, the pointed columns 115 will handle the bubbles generated when the water flow contacts the steam, facilitating the discharge. The holes provided on the surface of the fixed orifice plate 108 reduce the influence on the water flow rate during the water flow process, improving the deaeration efficiency. Among the above components, the bubbles generated during the deaeration process of the flowing water are handled, avoiding excessive bubbles that will form a foam layer, resulting in a decrease in the water flow and an increase in the system resistance.

[0043] Among them, for the holes of the fixed orifice plate 108, these holes will not allow the bubbles to pass through. Excessive bubbles will accumulate on the surface of the fixed orifice plate 108. When rotating, they will be squeezed by the cleaning plate 111 to clean the bubbles.

[0044] During the rotation of the rotating long rod 107, the rotating rotating long rod 107 drives the cleaning plate 111 to rotate together. The cleaning plate 111 at the far end and the telescopic cleaning plate 109 will be squeezed by different positions on the inner wall. During this process, the inner wall will be cleaned, and the water droplets on the inner wall will be scraped. During this process, the scraped water droplets will flow downward along the ends of the telescopic cleaning plate 109 and the cleaning plate 111. During this process, the small water droplets generated after handling the bubbles are cleaned, avoiding the re-dissolution of oxygen into the small water droplets, which affects the deaeration efficiency. For the flowing water, it is avoided that the small water droplets form a water film, resulting in a cleaning dead zone and affecting the overall flow uniformity and gas-liquid contact effect.

[0045] During the rotation of the cleaning plate 111, there is a fixed rod 116 on the surface of the cleaning plate 111. When the cleaning plate 111 rotates to the bottom, the fixed rod 116 prevents the rotating block 117 connected thereto from rotating downward under the action of gravity. The rotating block 117 will rotate into the limiting block 118. At this time, the cleaning plate 111 will be restricted and will not contract. At this time, the cleaning plate 111 will squeeze the sliding hole plate 201, and the sliding hole plate 201 will drive the U-shaped sliding plate 203 on its surface to slide on the inner wall of the deaeration water tower 102. When the cleaning plate 111 moves away from the sliding hole plate 201, the tension spring 204 at the end of the U-shaped sliding plate 203 will be restored, restoring the U-shaped sliding plate 203, and thus restoring the sliding hole plate 201. During this process, the sliding hole plate 201 will swing slightly, swinging the flowing water. Under the action of the guide plate 202, the water will flow evenly from the holes of the sliding hole plate 201. During the process, the above components control the amount of flowing water, ensuring that the flowing water can flow evenly to each position, reducing the occurrence of dead zones, and improving the uniformity of the water flow.

[0046] During the up and down sliding of the U-shaped sliding plate 203, the fixed block 205 at the bottom of the U-shaped sliding plate 203 will squeeze the T-shaped slider 310. During this process, the T-shaped slider 310 will drive the rotating square block 307 to move forward, and the rotating square block 307 will squeeze the rotating hole plate 301. At this time, the rotating hole plate 301 will rotate. When the fixed block 205 rises, the restoring spring 311 on the inner wall of the deaeration water tower 102 will pull the T-shaped slider 310 back to its original position. At this time, the rotating square block 307 will be squeezed and will rotate and be restored under the action of the coil spring 309. During the up and down movement of the fixed block 205, the rotating square block 307 will continuously push the rotating hole plate 301, and the rotating hole plate 301 will continuously rotate. Among the above components, the rotating rotating hole plate 301 contacts the flowing water falling from the sliding hole plate 201. During the rotation process, the flowing water will stay on the surface of the rotating hole plate 301, enabling the flowing water to come into full contact with the steam for deaeration, and controlling the flow of the water.

[0047] Among them, the number of rotating hole plates 301 is set to two and is controlled by the hollow column 303. A ratchet wheel 304 is provided on the surface of the hollow column 303. Under the action of the telescopic long column 305, the ratchet wheel 304 prevents the rotating hole plate 301 from moving in the reverse direction after being pushed by the rotating square block 307.
