Description

Technical Field

[0001] This invention relates to the field of deaerator exhaust steam heat recovery technology, specifically to a heating deaerator exhaust steam heat recovery device. Background Technology

[0002] A steam deaerator is a device used to remove dissolved gases from water. It is mainly used in industrial fields, especially in places such as power plants and chemical plants that need to treat large amounts of water. The deaerator feed water is mainly demineralized water, which enters the deaerator tower and is fully heated and deoxygenated by steam. Boiler feedwater deaeration is usually carried out by thermal deaeration. During deaeration, the deaerator produces waste gas, which is discharged through the flue pipe at the top of the deaerator. However, the steam generated during the operation of the deaerator is also easily discharged with the waste gas. This discharged steam is called exhaust steam. When the steam is discharged with the waste gas, it carries away the heat inside the deaerator, resulting in a waste of energy inside the deaerator. Summary of the Invention

[0008] Furthermore, the end of the positioning tube away from the circulation tube passes through the water supply device and extends into the interior of the water supply device; the bottom of the arc-shaped absorbent cotton extends to the outer bottom of the arc frame; and the end of the circular hole tube away from the arc frame passes through the water supply device and extends to the outer end of the water supply device.

[0009] Furthermore, the impurity removal component includes a filter frame, the bottom of which is fixedly connected to the bottom of the inner wall of the processing frame, a spring fixedly connected to the top of the inner wall of the processing frame, a circular scraper fixedly connected to the bottom of the spring, a vertical rod fixedly connected to the bottom of the circular scraper, a connecting plate fixedly connected to the bottom of the vertical rod, and the end of the connecting plate fixedly connected to the upper surface of the electric push rod.

[0010] Furthermore, the inner wall of the circular scraper is in contact with the surface of the filter frame, the surface of the circular scraper is in contact with the inner wall of the processing frame, and the bottom of the vertical rod penetrates the processing frame and extends to the bottom outer end of the processing frame.

[0011] Furthermore, the shock-absorbing component includes a round rod, the top of which is fixedly connected to the bottom of a fixing plate. A cross is fixedly connected to the surface of the round rod, a limiting ring is fixedly connected to the end of the cross, an agitator is fixedly connected to the bottom of the cross, a bracket is fixedly connected to the top of the limiting ring, and an arc plate is fixedly connected to the top of the bracket. The bottom of the round rod penetrates the water supply device and extends into the interior of the water supply device. The cross and the limiting ring are located inside the water supply device. The surface of the arc plate is adapted to the inner wall of the arc frame, and the arc plate is located below the arc frame.

[0012] Furthermore, the pressurizing component includes a synchronizing plate, the end of which is fixedly connected to the surface of the connecting plate, a moving rod is fixedly connected to the top of the synchronizing plate, a sealing disc is fixedly connected to the top of the moving rod, and a round hole block is connected to the end of the one-way air outlet valve pipe away from the air cylinder frame.

[0013] Furthermore, the end of the one-way air outlet valve pipe away from the air cylinder frame passes through the bend and extends into the interior of the bend, the air outlet end of the circular hole block is set downward, and the surface of the sealing disc is in contact with the inner wall of the air cylinder frame.

[0014] The present invention has the following beneficial effects: This invention supplies water to a deaerator via a connection between a water supply device and a transmission pipe. Demineralized water enters the deaerator and is thoroughly heated by steam for deoxygenation. Exhaust gas from the deaerator enters the bend through an exhaust pipe, along with some steam. The steam and exhaust gas then pass through a processing rack into a connecting pipe and flow in a circular pattern into a circulation pipe. The heat carried by the steam is concentrated inside the recovery rack as it flows through the circulation pipe. The recovery rack then uses this recovered heat to heat the water supply device, thus utilizing the heat to power the water supply system. The demineralized water is heated internally and then sent to the deaerator to fully utilize the heat, reduce the amount of high-quality steam used, and achieve the goal of pollution-free, energy-saving and environmentally friendly emissions. The moisture in the steam is absorbed by the arc-shaped absorbent cotton inside the arc-shaped frame. The exhaust gas entering the water supply device is discharged through the round hole pipe to achieve the purpose of discharge. The moisture entering the arc-shaped absorbent cotton drips into the water supply device for recycling. The residual steam discharged from the deaerator is recovered using a circulation pipe and a recovery frame. The heat is used to heat the demineralized water and recover the steam condensate for reuse.

[0015] After the exhaust gas and steam enter the interior of the treatment rack, they pass through the filter rack and into the connecting pipe. The filter rack filters impurities in the exhaust gas and steam, reducing emissions pollution. When the electric actuator is started to move up and down, it pushes the vertical rod to move synchronously through the connecting plate. As the vertical rod moves, it pushes the circular scraper to move on the surface of the filter rack, cleaning the surface of the filter rack and preventing impurities from accumulating on the surface of the filter rack and affecting the filtration effect.

[0016] When the electric actuator of this invention moves, it drives the fixed plate to move via the connecting rod. When the fixed plate moves, it drives the cross and the limiting ring to move via the round rod. When the cross moves, it drives the stirring plate to move inside the water supply device. When the stirring plate moves, it stirs the demineralized water inside the water supply device, preventing the hot steam from mixing with the calm demineralized water and causing water hammer and vibration.

[0017] In this invention, the linkage plate moves by pushing the sealing disc inside the gas cylinder frame via a moving rod. When the sealing disc moves upward, it pushes gas into the one-way outlet valve pipe. The gas pressure opens the one-way outlet valve pipe, transmitting the gas to the inside of the circular hole block. The gas moves downward through the circular hole block into the curved pipe, using the gas to drive steam to flow rapidly inside the connecting pipe. This allows the steam to quickly enter the circulation pipe for heat recovery, improving the efficiency of steam heat recovery. When the sealing disc moves downward, the one-way outlet valve pipe closes while the one-way inlet valve pipe opens. The movement of the sealing disc accelerates the flow of steam inside the connecting pipe, further improving the efficiency of steam heat recovery. When the limiting ring moves, it pushes the arc plate to move via the bracket. The arc plate squeezes the center of the arc-shaped absorbent cotton, allowing the moisture in the arc-shaped absorbent cotton to quickly enter the water supply device.

[0018] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Detailed Implementation

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Please see Figures 1-10 As shown, this invention is a waste steam heat recovery device for a heating deaerator, including a deaerator 1, a support base 3 fixedly connected to the bottom of the deaerator 1, an exhaust pipe 4 fixedly connected to the top of the deaerator 1, a transmission pipe 11 connected to the top of the deaerator 1, a water supply device 5 connected to the end of the transmission pipe 11 away from the deaerator 1, a recovery rack 6 fixedly connected to the bottom of the water supply device 5, and valve pipes 2 connected to the ends of the deaerator 1 and the water supply device 5 that are away from each other. It also includes: The recycling component 7 includes a bend 20, the end of which is connected to the upper surface of the exhaust pipe 4, and the bottom of the bend 20 is connected to a processing rack 21. The impurity removal component 8 includes a base 36, the end of which is fixedly connected to the surface of the support base 3, and an electric push rod 35 is fixedly connected to the top of the base 36. The shock-absorbing component 9 includes a linkage rod 40, the bottom of which is fixedly connected to the top of the electric actuator 35, and a fixing plate 41 is fixedly connected to the top of the linkage rod 40. The booster component 10 includes a one-way exhaust valve pipe 50, the bottom of which is connected to an air cylinder frame 52, and the top of the air cylinder frame 52 is connected to a one-way intake valve pipe 51.

[0024] There are two support bases 3, which are symmetrically arranged with the deaerator 1 as the center. The top of the water supply device 5 extends to the top outer end of the recycling rack 6, and the top of the recycling rack 6 is in contact with the surface of the water supply device 5.

[0025] The recovery component 7 includes a connecting pipe 22, the top of which is connected to the bottom of the processing rack 21. A circulation pipe 23 is connected to the end of the connecting pipe 22 away from the processing rack 21. A positioning pipe 24 is connected to the end of the circulation pipe 23 away from the connecting pipe 22. An arc-shaped frame 26 is connected to the end of the positioning pipe 24 away from the circulation pipe 23. A perforated pipe 27 is connected to the end of the arc-shaped frame 26 away from the positioning pipe 24. Arc-shaped absorbent cotton 25 is inserted into the inner wall of the arc-shaped frame 26. The exhaust gas generated by the deaerator 1 during operation enters the interior of the recovery component 7 through the exhaust pipe 4. The steam discharged with the exhaust gas also flows with the exhaust gas. Upon entering the recovery component 7, exhaust gas and steam flow within it. The circulation pipe 23 within the recovery component 7 is circulated within the recovery rack 6. As the exhaust gas and steam flow through the circulation pipe 23, the heat from the exhaust gas and steam is concentrated within the recovery rack 6. The recovery rack 6 can then use the recovered heat to heat the water supply device 5, thereby achieving the purpose of heat recovery. The recovered heat is used to heat the demineralized water inside the water supply device 5, ensuring that the demineralized water entering the deaerator 1 has a certain temperature, thus improving the working efficiency of the deaerator 1.

[0026] The end of the connecting pipe 22 away from the processing rack 21 passes through the recycling rack 6 and extends into the interior of the recycling rack 6. The circulation pipe 23 is located inside the recycling rack 6. The surface of the water supply device 5 is in contact with the surface of the circulation pipe 23. The top of the positioning pipe 24 passes through the recycling rack 6 and extends to the top outer end of the recycling rack 6.

[0027] The end of the positioning tube 24 away from the circulation tube 23 passes through the water supply device 5 and extends into the interior of the water supply device 5. The bottom of the arc-shaped absorbent cotton 25 extends to the bottom outer end of the arc frame 26. The end of the round hole tube 27 away from the arc frame 26 passes through the water supply device 5 and extends to the outer end of the water supply device 5.

[0028] The impurity removal component 8 includes a filter frame 31. The bottom of the filter frame 31 is fixedly connected to the bottom of the inner wall of the processing frame 21. A spring 30 is fixedly connected to the top of the inner wall of the processing frame 21. A circular scraper 32 is fixedly connected to the bottom of the spring 30. A vertical rod 33 is fixedly connected to the bottom of the circular scraper 32. A connecting plate 34 is fixedly connected to the bottom of the vertical rod 33. The end of the connecting plate 34 is fixedly connected to the upper surface of the electric push rod 35. During operation, the impurity removal component 8 cleans the inner wall of the exhaust gas and steam. By filtering the exhaust gas and steam through the impurity removal component 8, impurities in the exhaust gas and steam are prevented from entering the water supply device 5 and the deaerator 1 and causing blockage. The impurity removal component 8 has a self-cleaning function, which can clean itself while filtering the exhaust gas and steam, thereby improving the filtration effect of the impurity removal component 8.

[0029] The inner wall of the circular scraper 32 is in contact with the surface of the filter frame 31, and the surface of the circular scraper 32 is in contact with the inner wall of the treatment frame 21. The bottom of the vertical rod 33 passes through the treatment frame 21 and extends to the bottom outer end of the treatment frame 21.

[0030] The shock-absorbing component 9 includes a round rod 42, the top of which is fixedly connected to the bottom of a fixed plate 41. A cross 43 is fixedly connected to the surface of the round rod 42. A limit ring 44 is fixedly connected to the end of the cross 43. An agitator 46 is fixedly connected to the bottom of the cross 43. A bracket 45 is fixedly connected to the top of the limit ring 44. An arc plate 47 is fixedly connected to the top of the bracket 45. The bottom of the round rod 42 passes through the water supply device 5 and extends into the interior of the water supply device 5. The cross 43 and the limit ring 44 are located inside the water supply device 5. The surface of the arc plate 47 is adapted to the inner wall of the arc frame 26. The arc plate 47 is located below the arc frame 26. When the impurity removal component 8 is in operation, it will drive the shock-absorbing component 9 to move inside the water supply device 5. The shock-absorbing component 9 agitates the demineralized water inside the water supply device 5, preventing the demineralized water from remaining stagnant inside the water supply device 5. The flow of demineralized water inside the water supply device 5 can prevent hot steam from mixing with the calm demineralized water, which would cause water hammer and vibration.

[0031] The booster component 10 includes a synchronizing plate 53, the end of which is fixedly connected to the surface of the connecting plate 34. A moving rod 54 is fixedly connected to the top of the synchronizing plate 53, and a sealing disc 55 is fixedly connected to the top of the moving rod 54. A circular hole block 56 is connected to the end of the one-way exhaust valve pipe 50 away from the gas cylinder frame 52. When the impurity removal component 8 is working, it will simultaneously drive the booster component 10 to work. The booster component 10 will reciprocate and circulate with the operation of the impurity removal component 8. When the booster component 10 is working, it will push the gas into the interior of the recovery component 7, so that the waste gas and steam can flow quickly into the interior of the circulation pipe 23, avoiding the waste gas and steam from losing a lot of heat during the discharge process, which would affect the recovery effect.

[0032] One end of the one-way air outlet valve pipe 50, away from the air cylinder frame 52, passes through the bend 20 and extends into the interior of the bend 20. The air outlet end of the round hole block 56 is set downward, and the surface of the sealing disc 55 is in contact with the inner wall of the air cylinder frame 52.

[0033] In operation, the deaerator 1 is supplied with water through the connection between the water supply device 5 and the transmission pipe 11. The demineralized water enters the deaerator 1 and is fully heated and deoxygenated by steam. The exhaust gas generated by the deaerator 1 enters the bend 20 through the exhaust pipe 4. At this time, some steam also enters the bend 20 along with the exhaust gas. The steam and exhaust gas enter the connecting pipe 22 through the treatment rack 21 and flow in a ring shape into the circulation pipe 23. The heat carried by the steam is concentrated in the recovery rack 6 as it flows in the circulation pipe 23. The recovery rack 6 can then use the recovered heat to heat the water supply device 5, thereby heating the demineralized water inside the water supply device 5. The heated demineralized water is then sent to the deaerator 1. Inside, in order to fully utilize heat and reduce the use of high-quality steam, the goal of pollution-free, energy-saving, and environmentally friendly emissions is achieved. Moisture in the steam enters the interior of the arc-shaped frame 26 and is absorbed by the arc-shaped absorbent cotton 25. Exhaust gas entering the water supply device 5 is discharged through the round-hole pipe 27 to achieve the purpose of emission. Moisture entering the arc-shaped absorbent cotton 25 drips back into the water supply device 5 for recycling. After the exhaust gas and steam enter the interior of the treatment rack 21, they pass through the filter rack 31 and enter the interior of the connecting pipe 22. The filter rack 31 filters impurities in the exhaust gas and steam, reducing emissions pollution. When the electric actuator 35 is started to move up and down, the electric actuator 35 pushes the vertical rod 33 synchronously through the connecting plate 34. When the vertical rod 33 moves, it pushes the circular scraper 32 to move on the surface of the filter frame 31, cleaning the surface of the filter frame 31 and preventing impurities from accumulating on the surface of the filter frame 31 and affecting the filtration effect. When the electric push rod 35 moves, it drives the fixed plate 41 to move via the connecting rod 40. When the fixed plate 41 moves, it drives the cross 43 and the limiting ring 44 to move via the circular rod 42. When the cross 43 moves, it drives the stirring plate 46 to move inside the water supply device 5. When the stirring plate 46 moves, it agitates the demineralized water inside the water supply device 5, preventing hot steam from mixing with the calm demineralized water and causing water hammer and vibration. When the connecting plate 34 moves, it pushes the sealing plate 55 inside the air cylinder frame 52 via the moving rod 54. When the sealing disc 55 moves upward, it pushes the gas into the one-way outlet valve pipe 50. The gas pressure opens the one-way outlet valve pipe 50, transferring the gas to the inside of the circular hole block 56. The gas moves downward through the circular hole block 56 towards the bend 20, using the gas to drive the steam to flow rapidly inside the connecting pipe 22, allowing the steam to quickly enter the circulation pipe 23 for heat recovery, thus improving the efficiency of steam heat recovery. When the sealing disc 55 moves downward, the one-way outlet valve pipe 50 closes while the one-way inlet valve pipe 51 opens. The movement of the sealing disc 55 accelerates the flow of steam inside the connecting pipe 22, further improving the efficiency of steam heat recovery. When the limiting ring 44 moves, it pushes the arc plate 47 to move via the bracket 45.The arc-shaped plate 47 squeezes the center of the arc-shaped absorbent cotton 25, causing the moisture in the absorbent cotton 25 to quickly enter the water supply device 5.
