Description

Technical Field

[0001] This utility model relates to the field of boiler feedwater technology, and in particular to a deoxygenation and desalination device for gas turbine boiler feedwater. Background Technology

[0002] Gas turbine boilers require a large amount of high-purity feedwater during operation to prevent scaling and corrosion on the boiler's heating surfaces and to reduce thermal efficiency. The feedwater usually comes from industrial water or tap water, but it contains dissolved oxygen, carbon dioxide, and various salts (such as calcium and magnesium ions). These impurities can cause boiler corrosion and scaling, affecting equipment life and operating efficiency.

[0003] In existing technologies, such as the "Energy-Saving Boiler Feedwater System for Gas Turbine Combined Cycle Power Plant" (CN220119358U), the system includes a first demineralized water tank, a condenser, a waste heat boiler deaerator, a waste heat boiler deaerator water tank, and a second demineralized water tank. The first demineralized water tank is connected to the condenser via a first pipeline. The first pipeline is sequentially equipped with a first outlet manual shut-off valve, a normal feedwater electric switch valve, a feedwater flow meter, a first maintenance isolation valve, a normal feedwater regulating valve, and a second maintenance isolation valve. While this technology has advantages such as reduced pipeline losses and energy and water savings, it differs from traditional methods... The problem is that this technology uses two separate devices for deoxygenation and desalination of the makeup water, resulting in a complex structure, large space occupation, and limited water treatment efficiency. In addition, for deoxygenation, traditional methods often use simple additives, which result in low contact efficiency between water and deoxygenating agents, leading to unstable deoxygenation effects, residual oxygen, and pipe corrosion. Furthermore, traditional desalination equipment mostly uses static filtration, which results in uneven water flow distribution, making the filter layer prone to clogging, thus reducing the desalination effect and affecting water quality. Utility Model Content

A defoaming pipe is connected to one side of the top of the deaerator cylinder. The position of the defoaming pipe corresponds to the position of the bottom of the baffles. The water level line inside the deaerator cylinder is located at the bottom of the inlet end of the defoaming pipe.

[0009] Preferably, a partition is rotatably connected to the bottom of the rotating drum, and multiple connecting blocks are fixedly connected in a ring at equal intervals to the outside of the partition.

[0015] The beneficial effects of this utility model are:

[0016] 1. By coordinating the deoxygenation, desalination, and flow-gathering components, the boiler feedwater treatment process is optimized, achieving efficient integrated deoxygenation and desalination. This avoids the problems of large space occupation and uneven fluid distribution caused by the split structure of traditional equipment. The introduction of the rotating structure improves water flow disturbance, making the deoxygenation and desalination process more thorough. At the same time, the multi-stage filtration design enhances the ability to remove impurities, reduces clogging, and improves system stability. The overall equipment structure is compact, occupies a small area, reduces maintenance difficulty, and improves the efficiency and reliability of boiler feedwater treatment.

[0017] 2. The deoxygenation component employs a rotating drum structure with a first and second vortex plate inside. The vortex plates of different lengths create a high-speed rotating water flow, ensuring full contact between the water and the deoxygenating agent and improving deoxygenation efficiency. Simultaneously, due to the low density of the gas, it will accumulate on the outside of the drum during rotation. The propeller rotation then forces the accumulated gas and water on the outside of the drum to be discharged to the top of the drum. At this point, the gas separates from the water, and the oxygen at the top of the drum is drawn out through the oxygen exhaust pipe, thus achieving rapid deoxygenation. Meanwhile, because the dissolved salt has a higher density, it will move towards the inner wall of the deoxygenation drum and settle downwards.

[0018] 3. The desalination component uses a rotating column structure to drive the first and second pusher plates, which makes the water flow evenly distributed, increases the contact area between the water and the filter screen, and improves the desalination efficiency. At the same time, two-stage filter screens are set inside. The first filter screen is connected to the rotating column and can rotate with the water flow to avoid the accumulation of impurities and reduce the risk of clogging. Meanwhile, the third pusher plate further optimizes the water flow direction and improves the filtration effect.

[0019] 4. The flow-gathering component, composed of multiple arc-shaped plates and conical blocks, effectively guides the water flow, causing the deoxygenated water to flow in a concentrated manner to the desalination area, thus improving the stability of the water flow. At the same time, the flow-guiding effect of multiple arc-shaped plates also avoids water flow turbulence, optimizes water flow distribution, and makes the water more uniform when entering the desalination component, thereby enhancing the desalination effect.

[0030] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments.

[0032] Such as this utility model Figures 1 to 7The diagram shows a deaeration and desalination device for boiler feedwater from a gas turbine, including a deaeration cylinder 1. A mounting frame 4 is fixedly connected to the outside of the deaeration cylinder 1. An deaeration assembly for deaerating the feedwater is installed inside the deaeration cylinder 1. The deaeration assembly includes a rotating drum 13 rotatably connected inside the deaeration cylinder 1. A first swirl plate 16 and a second swirl plate 17 are fixedly connected to the outside of the rotating drum 13. The length of the first swirl plate 16 is longer than the length of the second swirl plate 17. An inlet pipe 7 and a feed pipe 9 are connected to the top of the deaeration cylinder 1, positioned at the top between the deaeration cylinder 1 and the rotating drum 13. A converging cylinder 2 is connected to the bottom of the deaeration cylinder 1, and a desalination cylinder 3 is connected to the bottom of the converging cylinder 2. The desalination cylinder 3 is internally equipped with… A desalination assembly for desalinizing makeup water is provided. The desalination assembly includes a rotating column 25 rotatably connected inside the desalination cylinder 3. A first pusher plate 26 and a second pusher plate 27 are fixedly connected to the outside of the rotating column 25. A first filter screen 29 is rotatably connected inside the desalination cylinder 3. A second filter screen 31 is fixedly connected inside the desalination cylinder 3. The first filter screen 29 is located between the first pusher plate 26 and the second filter screen 31. A flow-gathering assembly is provided on the top of the first pusher plate 26. The flow-gathering assembly is used in conjunction with the desalination assembly. The desalination assembly and the deoxygenation assembly work together to achieve the effects of deoxygenation and desalination in one device.

[0033] By coordinating the deoxygenation, desalination, and flow-converging components, the boiler feedwater treatment process is optimized, achieving efficient integrated deoxygenation and desalination. This avoids the problems of large space occupation and uneven fluid distribution caused by the separate structure of traditional equipment. The introduction of the rotating structure increases water flow disturbance, making the deoxygenation and desalination processes more thorough. At the same time, the multi-stage filtration design enhances the ability to remove impurities, reduces clogging, and improves system stability. The overall equipment has a compact structure, small footprint, reduced maintenance difficulty, and improved efficiency and reliability of boiler feedwater treatment.

[0034] like Figures 1 to 5 As shown, a propeller 21 is installed inside the rotating drum 13. The top of the propeller 21 is fixedly connected to the top of the rotating drum 13. A connecting shaft 6 is rotatably connected to the top of the deaerator 1. The bottom end of the connecting shaft 6 is fixedly connected to the top of the propeller 21 and the top of the rotating drum 13. A motor 5 is fixedly connected to the top of the deaerator 1. The output end of the motor 5 is fixedly connected to the top end of the connecting shaft 6.

[0035] By setting up a deoxygenation assembly with a rotating drum 13 structure, and internally setting a first vortex plate 16 and a second vortex plate 17, a high-speed rotating water flow is formed by the vortex plates of different lengths, so that the water and the deoxygenating agent can fully contact each other, thereby improving the deoxygenation efficiency. In use, the makeup water is input into the deoxygenation drum 1 through the liquid inlet pipe 7. At this time, the deoxygenating agent is added into the deoxygenation drum 1 through the feeding pipe 9. Then, the motor 5 is started, which causes the liquid outlet 15 to rotate with the first vortex plate 16 and the second vortex plate 17, thereby promoting full contact between the deoxygenating agent and the water, thereby improving the deoxygenation efficiency.

[0036] like Figures 1 to 5 As shown, the top of the deaerator cylinder 1 is connected to the oxygen discharge pipe 8. The output end of the oxygen discharge pipe 8 is located at the top of the inside of the rotating cylinder 13. Multiple oxygen inlet holes 18 are opened in a ring at equal intervals at the bottom of the rotating cylinder 13. A liquid outlet 15 is opened inside the top of the rotating cylinder 13.

[0037] With the propeller 21, oxygen inlet 18, and liquid outlet 15 configured, the propeller 21 will rotate simultaneously when the rotating drum 13 rotates. At this time, due to the low density of the gas, it will accumulate on the outside of the rotating drum 13 as it rotates. Then, the rotation of the propeller 21 will cause the gas and water accumulated on the outside of the rotating drum 13 to be discharged from the inside of the oxygen inlet 18 to the top of the rotating drum 13. At this time, the gas separates from the water, and then the oxygen is sucked out from the top of the rotating drum 13 through the oxygen exhaust pipe 8, thereby achieving rapid deoxygenation. At the same time, water will fall from the inside of the liquid outlet 15 into the outside of the rotating drum 13 for subsequent desalination.

[0038] like Figures 1 to 5 As shown, multiple levers 14 are fixedly connected in a ring at equal intervals on the outside of the top of the rotating cylinder 13. The levers 14 are located at the bottom of the liquid outlet 15. A defoaming pipe 10 is connected to one side of the top of the deaerator cylinder 1. The position of the defoaming pipe 10 corresponds to the position of the bottom of the levers 14. The water level line inside the deaerator cylinder 1 is located at the bottom of the inlet end of the defoaming pipe 10.

[0039] When water reacts with the defoaming agent, bubbles are generated by the set desiccant 14 and defoaming tube 10. These bubbles will gather at the top of the water. Since the bubbles contain dissolved oxygen, when the rotating drum 13 rotates, the desiccant 14 will rotate, causing the desiccant 14 to scrape the bubbles at the top of the water to the input end of the defoaming tube 10, thereby removing the bubbles from the inside of the defoaming tube 10 and achieving the effect of completely removing dissolved oxygen.

[0040] like Figure 2 and Figure 3 As shown, a partition 19 is rotatably connected to the bottom of the rotating drum 13. Multiple connecting blocks 20 are fixedly connected in a ring at equal intervals on the outside of the partition 19. The side of the connecting block 20 away from the partition 19 is fixedly connected to the inner wall of the bottom of the deaerator drum 1.

[0041] By setting up baffles 19 and connecting blocks 20, the function of baffles 19 is to cause dissolved oxygen to accumulate at the top of baffles 19 when the rotating drum 13 rotates, due to the low gas density, thus preventing water without deoxygenation from entering the bottom. At the same time, through the multiple connecting blocks 20, due to the higher density of dissolved salt, it will move towards the inner wall of the deoxygenation cylinder 1 under the influence of the first swirl plate 16 and the second swirl plate 17, thereby causing water containing dissolved salt to enter the interior of the flow-gathering cylinder 2 between the multiple connecting blocks 20, thus facilitating the flow of water.

[0042] like Figure 2 , Figure 4 , Figure 6 and Figure 7 As shown, the flow-concentrating assembly includes multiple arc-shaped plates 24 that are fixedly connected in a ring at equal intervals inside the top of the flow-concentrating cylinder 2. Conical blocks 23 are fixedly connected to the multiple arc-shaped plates 24 away from the flow-concentrating cylinder 2. The multiple arc-shaped plates 24 are located at the bottom of the partition plate 19. A sleeve 22 is fixedly connected to the bottom of the flow-concentrating cylinder 2, and a gap is left between the sleeve 22 and the conical blocks 23.

[0043] The flow-gathering component, consisting of multiple arc-shaped plates 24 and conical blocks 23, guides water as it flows from between multiple connecting blocks 20 to the top of the flow-gathering cylinder 2. This guides the water to gather at the top of the conical blocks 23, effectively directing the water flow and concentrating the deoxygenated water towards the desalination area, thus improving the stability of the water flow. At the same time, the flow-guiding effect of the multiple arc-shaped plates 24 also prevents water flow turbulence, optimizes the water flow distribution, and makes the water more uniform when entering the desalination component, thereby enhancing the desalination effect.

[0044] like Figure 2 and Figure 4 As shown, the top of the rotating column 25 is fixedly connected to the bottom of the rotating cylinder 13 through the inside of the conical block 23 and the partition plate 19 via a shaft. The length of the first pusher plate 26 is greater than the length of the second pusher plate 27, and the length of the first pusher plate 26 extends beyond the outside of the conical block 23.

[0045] By adjusting the length of the first pusher plate 26, when water gathers at the top of the conical block 23, it will flow from the gap between the bottom of the sleeve 22 and the top of the conical block 23 into the top of the first pusher plate 26. Then, by rotating the first pusher plate 26, the water can be dispersed, causing impurities inside the water to separate from the water, thus facilitating subsequent filtration.

[0046] like Figure 1 , Figure 2 , Figure 4 and Figure 6As shown, a connecting rod 28 is fixedly connected to the outside of the rotating column 25. The end of the connecting rod 28 away from the rotating column 25 is fixedly connected to the inner wall of the first filter screen 29. Multiple third pusher plates 30 are fixedly connected in a ring at equal intervals to the outside of the first filter screen 29. The third pusher plates 30 are located between the second filter screen 31 and the first filter screen 29. The size of the holes inside the first filter screen 29 is larger than the size of the holes inside the second filter screen 31. A liquid outlet pipe 12 is connected to one side of the desalination cylinder 3. The position of the liquid outlet pipe 12 corresponds to the position of the second filter screen 31. Two desalination pipes 11 are connected to the bottom of the desalination cylinder 3. The positions of the two desalination pipes 11 are located at the bottom between the first filter screen 29 and the second pusher plate 27, and at the bottom between the second filter screen 31 and the first filter screen 29, respectively.

[0047] The desalination assembly employs a rotating column 25 structure. When the rotating drum 13 rotates, the rotating column 25 is driven to rotate via the shaft. This causes the first pusher plate 26 and the second pusher plate 27 to move, resulting in a uniform water flow distribution, increased contact area between the water and the filter screen, and improved desalination efficiency. Simultaneously, a two-stage filter is installed internally. The first filter screen 29 is connected to the rotating column 25 and rotates with the water flow, preventing impurity accumulation and reducing the risk of clogging. Large particles and dissolved salt are blocked between the first filter screen 29 and the rotating column 25, and then discharged through the desalination pipe 11. The second pusher plate 27, located outside the first filter screen 29, agitates the water flow between the second filter screen 31 and the first filter screen 29, further subdividing impurities. The second filter screen 31 filters fine impurities between the first and second filter screens, and then discharges the filtered water through the desalination pipe 11. Finally, the filtered water is transported to the gas turbine boiler through the liquid outlet pipe 12.
