Description

Technical Field

[0001] This utility model relates to the field of deaerator technology, specifically to an energy-saving thermal spray deaerator. Background Technology

[0002] Oxygen is the main corrosive substance in water. Water with high oxygen content will corrode the pipes and components it flows through. The resulting corrosion products will deposit on the pipe walls and furnace walls to form iron scale with poor heat transfer. Furthermore, corrosion will increase the risk of pipe bursts. Therefore, it is necessary to use a deaerator to deoxygenate the water. Thermal spray deaerator is one of the commonly used deaerators.

[0003] Traditional thermal spray deaerators typically employ only one deaeration method: the falling water mist generated within the deaeration head comes into full contact with rising steam. The water mist is heated by the steam, expelling dissolved oxygen and thus deaerating the water. However, due to the rapid falling speed of the water mist and the limited height of the deaeration head, the time for the water mist to be heated and deaerated by steam is short. A single deaeration process is insufficient to improve the deaeration effect. Furthermore, the fixed spray position and direction of the water mist result in uneven distribution, reducing the heat exchange efficiency between the water mist and steam, thereby lowering the deaeration efficiency. Additionally, the steam heated by the water mist carries the gases expelled from the water directly away from the deaeration head, failing to fully utilize the residual heat of the mixed gas and reducing the utilization rate of steam thermal energy. Utility Model Content

[0004] The purpose of this invention is to provide an energy-saving thermal spray deaerator with the advantages of good deaeration effect and high steam thermal energy utilization rate.

[0005] The technical solution of this utility model is as follows:

[0006] An energy-saving thermal spray deaerator includes a deaerator head and a deaerator water tank. The bottom of the deaerator head is connected to the top of the deaerator water tank. The deaerator head includes deaerator head A and deaerator head B. The bottom of deaerator head A is connected to the top of deaerator head B. A water inlet pipe is provided on the upper part of the side wall of deaerator head A. A mounting base is provided in the upper part of the interior of the deaerator head. The bottom of the mounting base is rotatably connected to the middle of a water spray pipe. Spray nozzles are evenly arranged along the length of the bottom of the water spray pipe. The inner port of the water inlet pipe is connected to the water spray pipe through the internal cavity of the mounting base. A rotating component for driving the water spray pipe to rotate is provided in the internal cavity of the mounting base. The upper part of the interior of deaerator head B is provided with packing material. Each of the deaerators has a grille on its upper and lower sides. Inside the deaerator head A, below the water spray pipe, is a heating steam device A. Inside the deaerator head B, below the packing material, is a heating steam device B. Heating steam devices A and B are each connected to a high-temperature steam source via steam pipes. The outer port of the water inlet pipe is connected to the outlet of the connecting pipe. The inlet of the connecting pipe is connected to a water source via a water supply pipe. A preheating component is fitted onto the connecting pipe. The top of the deaerator head A has an exhaust port. A steam-water separator is connected to the exhaust port. The outlet of the steam-water separator is connected to the inlet of the preheating component via an air supply pipe. The outlet of the preheating component is connected to an exhaust pipe leading to the steam discharge point.

[0007] Preferably, the rotating assembly includes a rotating rod and a rotating paddle. The rotating rod is provided along the axis of the vertical portion of the internal cavity of the mounting base. The axis of the rotating rod coincides with the rotation axis of the sprinkler pipe. The upper end of the rotating rod is rotatably connected to the mounting base, and the lower end of the rotating rod is fixedly connected to the sprinkler pipe. The rotating rod is provided with a rotating paddle on the portion of the internal cavity of the mounting base.

[0008] Preferably, the preheating component includes an insulation shell and a spiral air duct. The insulation shell is fitted onto the connecting pipe, and the insulation shell is provided with a spiral air duct that winds around the connecting pipe. The air inlet of the spiral air duct is connected to the air supply pipe, and the air outlet of the spiral air duct is connected to the exhaust pipe.

[0009] Preferably, the deoxygenated water tank is provided with a drain outlet at the bottom.

[0010] Preferably, the upper part of the side wall of the deoxygenated water tank is provided with an overflow port.

[0011] Preferably, a level gauge is provided on the side wall of the deoxygenated water tank.

[0012] The beneficial technical effects of this utility model are as follows:

[0013] 1. Water undergoes secondary water-oxygen separation within the deaerator head before falling into the deaerator water tank. This process ensures good deaeration, as the water is evenly dispersed to facilitate full contact with the steam, resulting in high deaeration efficiency. In deaerator head A, water flows along the water supply pipe, connecting pipe, inlet pipe, and mounting base into the sprinkler pipe. The sprinkler pipe rotates under the action of the rotating component. During this rotation, each nozzle sprays water downwards in the form of a water mist. The steam released by the heating steam device A encounters the evenly dispersed water mist and carries away the oxygen in the water mist, creating the first water-oxygen separation. In deaerator head B, the evenly falling water mist passes through the grid and falls into the packing material. The water mist takes a relatively long time to pass through the packing material. During this time, the steam released by the heating steam device B encounters the water mist in the packing material and carries away the oxygen in the water mist, creating the second water-oxygen separation. Finally, the deaerated water that has undergone secondary water-oxygen separation is collected in the deaerator water tank.

[0014] 2. After deoxygenation, the steam released by heating steam device A and heating steam device B is processed by steam-water separator and sent to the preheating component through the gas transmission pipe. The preheating component uses the residual heat of the steam to preheat the water in the connecting pipe, reducing the heating time of the water mist in deoxygenation head A. This not only improves the deoxygenation efficiency, but also increases the utilization rate of steam thermal energy. Attached Figure Description

Detailed Implementation

[0021] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0022] Example:

[0023] like Figures 1 to 4 As shown, this embodiment provides an energy-saving thermal spray deaerator, including a deaerator head and a deaerator water tank 1. The bottom of the deaerator head is connected to the top of the deaerator water tank 1. The deaerator head includes a deaerator head A2 and a deaerator head B3. The bottom of the deaerator head A2 is connected to the top of the deaerator head B3. A water inlet pipe 4 is provided on the upper part of the side wall of the deaerator head A2. A mounting base 5 is provided in the upper part of the interior of the deaerator head. The bottom of the mounting base 5 is rotatably connected to the middle of the sprinkler pipe 6. Spray nozzles 7 are evenly provided along the length of the bottom of the sprinkler pipe 6. The inner port of the water inlet pipe 4 is connected to the sprinkler pipe 6 through the internal cavity of the mounting base 5. A rotating component 8 for driving the sprinkler pipe 6 to rotate is provided in the internal cavity of the mounting base 5. A packing 9 is provided in the upper part of the interior of the deaerator head B3. The deaerator head B3 has packing material 9 on both the upper and lower sides of the packing material 9. The device is equipped with a grille 10. Inside the deaerator head A2, below the water spray pipe 6, there is a heating steam device A11. Inside the deaerator head B3, below the packing 9, there is a heating steam device B12. Heating steam devices A11 and B12 are each connected to a high-temperature steam source through a steam pipe 13. The outer port of the water inlet pipe 4 is connected to the outlet of the connecting pipe 14. The inlet of the connecting pipe 14 is connected to a water source through a water supply pipe 15. A preheating component 16 is fitted on the connecting pipe 14. The top of the deaerator head A2 is equipped with an exhaust port 17. A steam-water separator 18 is connected to the exhaust port 17. The outlet of the steam-water separator 18 is connected to the inlet of the preheating component 16 through an air supply pipe 19. The outlet of the preheating component 16 is connected to an exhaust pipe 20 leading to the steam discharge point.

[0024] After undergoing secondary water-oxygen separation in the deaerator head, the water falls into the deaerator water tank 1, resulting in good deaeration effect. The water can be evenly dispersed to ensure full contact with the steam, leading to high deaeration efficiency. In deaerator head A2, water flows along the water supply pipe 15, connecting pipe 14, inlet pipe 4, and mounting base 5 into the sprinkler pipe 6. The sprinkler pipe 6 rotates under the action of the rotating component 8. During the rotation of the sprinkler pipe 6, each nozzle 7 sprays water downwards in the form of water mist. The steam released by the heating steam device A11 encounters the evenly distributed water mist and carries away the oxygen in the water mist, creating the first water-oxygen separation. In deaerator head B3, the evenly falling mist passes through the grid 10 and falls into the packing 9. The mist takes a relatively long time to pass through the packing 9. During this period, the steam released by the heating steam device B12 encounters the mist in the packing 9 and carries away the oxygen in the mist, creating the second water-oxygen separation. Finally, the deaerated water that has undergone secondary water-oxygen separation is collected in the deaerator water tank 1. After deoxygenation, the steam released by heating steam device A11 and heating steam device B12 is processed by steam-water separator 18 and sent to preheating component 16 through gas pipeline 19. Preheating component 16 uses the residual heat of steam to preheat the water in connecting pipe 14, reducing the heating time of water mist in deoxygenation head A2, which not only improves deoxygenation efficiency, but also increases the utilization rate of steam thermal energy.

[0025] Furthermore, the rotating assembly 8 includes a rotating rod 21 and a rotating paddle 22. The vertical portion of the internal cavity of the mounting base 5 is provided with the rotating rod 21 along the axis. The axis of the rotating rod 21 coincides with the rotation axis of the sprinkler pipe 6. The upper end of the rotating rod 21 is rotatably connected to the mounting base 5, and the lower end of the rotating rod 21 is fixedly connected to the sprinkler pipe 6. The rotating rod 21 is provided with a rotating paddle 22 on the portion of the internal cavity of the mounting base 5.

[0026] Water flowing into the sprinkler pipe 6 through the internal cavity of the mounting base 5 drives the rotating paddle 22 to rotate. The rotating paddle 22 drives the sprinkler pipe 6, which is indirectly connected to the rotating rod 21, to rotate, so as to achieve the effect of synchronous rotation of the sprinkler pipe 6 when the nozzle 7 sprays water mist.

[0027] Furthermore, the preheating component 16 includes an insulation shell 23 and a spiral air passage 24. The insulation shell 23 is fitted onto the connecting pipe 14. The insulation shell 23 is provided with a spiral air passage 24 that is wound around the connecting pipe 14. The air inlet of the spiral air passage 24 is connected to the air supply pipe 19, and the air outlet of the spiral air passage 24 is connected to the exhaust pipe 20.

[0028] Steam is allowed to preheat the water in the connecting pipe 14 through the spiral air passage 24. The spiral air passage 24 is used to increase the contact area with the connecting pipe 14 and enhance the preheating effect. The heat insulation shell 23 is used to reduce the rate at which the heat of the steam is lost to the outside and improve the utilization rate of steam heat energy.

[0029] Furthermore, the bottom of the deoxygenated water tank 1 is provided with a drain outlet 25.

[0030] Users can release the deoxygenated water accumulated in the deoxygenated water tank 1 through the drain outlet 25.

[0031] Furthermore, the upper side wall of the deoxygenated water tank 1 is provided with an overflow port 26.

[0032] Excess deoxygenated water in the deoxygenated water tank 1 is discharged through the overflow port 26 to prevent excessive deoxygenated water from flowing into the deoxygenation head.

[0033] Furthermore, a level gauge 27 is installed on the side wall of the deoxygenated water tank 1.

[0034] Staff can check the amount of deoxygenated water in deoxygenated water tank 1 through level gauge 27.

[0035] Working principle and usage process of this utility model:

[0036] Water requiring deoxygenation flows into sprinkler pipe 6 via water supply pipe 15, connecting pipe 14, inlet pipe 4, and mounting base 5. The water flowing within the internal cavity of mounting base 5 drives rotating component 8, causing sprinkler pipe 6 to rotate. During the rotation of sprinkler pipe 6, each nozzle 7 sprays water downwards in the form of water mist. Steam released by heating steam device A11 encounters the evenly distributed water mist and carries away the oxygen in the water mist, creating the first water-oxygen separation. In deoxygenation head B3, the evenly falling mist passes through grid 10 and falls into packing 9. The mist takes a relatively long time to pass through packing 9. During this period, steam released by heating steam device B12 encounters the mist in packing 9 and carries away the oxygen in the mist, creating the second water-oxygen separation. Finally, the deoxygenated water after the second water-oxygen separation is collected in deoxygenated water tank 1.

[0037] The above are merely specific application examples of this utility model and do not constitute any limitation on the scope of protection of this utility model. All technical solutions formed by equivalent transformations or equivalent substitutions fall within the scope of protection of this utility model.
