Description

Technical Field

[0001] The invention relates to the technical field of water-cooled walls, in particular to a full-membrane water-cooled wall structure for settling and removing ash particles. Background Art

[0002] When the water-cooled wall was originally designed, its purpose was not to absorb heat, but to cool the furnace to prevent it from being damaged by high temperatures. Later, due to its excellent heat exchange function, it gradually replaced the steam drum as the main heat-receiving part of the boiler. It is laid on the inner wall of the boiler furnace and is composed of many parallel tubes. The function of the water-cooled wall is to absorb the radiant heat from the high-temperature flame or flue gas in the furnace, generate steam or hot water within the tubes, and reduce the temperature of the furnace wall to protect the furnace wall. In large-capacity boilers, the flame temperature is very high and the intensity of heat radiation is very high. With the exception of a few small-capacity boilers, modern water-tube boilers all use the water-cooled wall as the main evaporation heating surface in the boiler. However, the size of the boiler's flue gas or hot gas outlet is limited, and most existing water-cooled walls can only block and absorb the heat from the first wave of flue gas and hot gas discharged from the boiler. After the flue gas impact, it rebounds and flows in other directions, thus absorbing a limited amount of heat. Summary of the Invention

[0012] Compared with the prior art, the present invention provides a full-membrane water-cooled wall structure for ash particle sedimentation and removal, which has the following beneficial effects:

[0013] 1. The full-membrane water-cooled wall structure for ash particle sedimentation and removal can be connected to the water pipe through the horizontal pipe and the short pipe, so that water can be injected into it from one of them, so that the water will enter several vertical pipes and each vertical box, and as the water is continuously injected, the water will flow in the dry vertical pipes and each vertical box and each inclined box, and then the guide frame on the device is set at the smoke outlet, so that the hot smoke will enter the guide frame, and then the smoke will flow upward along the several vertical boxes, and then the smoke will flow upward along each inclined box, so that it will be cooled by the water flowing in the vertical pipes in the inclined box, the vertical box and the wall panel, and at the same time, the water that absorbs superheat will be continuously discharged for utilization, so that the contact area of ​​the smoke can be increased through the inclined box and the vertical box, so that the cooling efficiency can be improved, thereby improving the effect of the water-cooled wall in a limited space.

[0014] 2. The full-membrane water-cooled wall structure used for ash particle sedimentation and removal can intercept the flue gas moving to the right through each connecting block and square plate, so that the heat generated by the impact of the flue gas can be intercepted by setting fireproof mud on the connecting block and the square plate. At the same time, it is convenient for users to disassemble the connecting block and the square plate, so that it is convenient for users to replace the fireproof mud, and avoid cracks caused by long-term use of the fireproof mud affecting the effect. At the same time, the fireproof mud can be applied to the surface of the box, and the surface of the box can be made rough through the protrusions, so that the particles in the passing flue gas can adhere to the fireproof mud on the box. In this way, after using it for a period of time, the box can be pulled out and the particles in the flue gas can be cleaned while replacing the fireproof mud.

[0015] 3. The full-membrane water-cooled wall structure used for ash particle sedimentation and removal can connect each vertical box in pairs through the small tubes on the connecting box, which can promote the interaction of water in each vertical box. At the same time, the upward-moving flue gas can be guided by the inclined setting of the connecting box, and the flue gas can be cooled, thereby further improving the effect of the water-cooled wall.

[0016] 4. The full-membrane water-cooled wall structure used for ash particle sedimentation and removal, through the round box and the pressure spring, can drive the moving column forward when the pressure of the water in the water-cooled wall is too high due to the high temperature, thereby driving the moving circular plate forward, so that the pressure can be relieved, thereby avoiding the internal pipe from bursting.

[0017] 5. The full-membrane water-cooled wall structure used for ash particle sedimentation and removal drives the moving column forward due to the excessive pressure generated by the high temperature of the water in the water-cooled wall. When the pressure continues to increase, the moving column will continue to move forward. When the moving column moves in front of the two notches, the water in the water-cooled wall will enter the pressure relief box through the two notches, and the water will be discharged through the pressure relief box. In this way, the pressure can be further relieved to avoid pipe burst. When the pressure relief is completed, the rebound of the pressure spring will drive the moving column to return to its original position.

[0018] 6. The full-membrane water-cooled wall structure used for ash particle sedimentation and removal, by pushing the collection box under the shielding tube, when the pressure inside the water-cooled wall is too high, the water discharged from the pressure relief box will impact the baffle, and then the water will be blocked by the shielding tube, so that the water can only be discharged into the interior through the water outlet, and the discharged water will be recycled and reused, while avoiding splashing water to scald people. The position of the internal buoyancy plate can be penetrated by a transparent strip, so that the amount of water collected in the collection box can be judged by the position of the buoyancy plate.

[0019] 7. The full-membrane water-cooled wall structure used for ash particle sedimentation and removal can install and disassemble the inclined box through the installation plate, bolts and fixing plate. When the device has been used for a long time, the inclined box can be removed and the tool can be inserted into the vertical box through the through slot to clean the scale and other impurities inside. The bolts and installation plates and other structures can be protected by the l connecting strip. BRIEF DESCRIPTION OF THE DRAWINGS

After being connected to the water pipe through the horizontal pipe 7 and the short pipe 15, water can be injected into it from one of them, so that the water will enter the several vertical pipes 13 and each vertical box 12. As the water is continuously injected, the water will flow through the vertical pipes 13, each vertical box 12 and each inclined box 21. The guide frame 8 on the device is then set at the smoke outlet, so that the hot smoke will enter the guide frame 8, and then the smoke will flow upward along the several vertical boxes 12, and thus the smoke will flow upward along each inclined box 21. In this way, it will be cooled by the water flowing in the inclined box 21, the vertical box 12 and the vertical pipe 13 in the wall panel 1, and at the same time, the water that has absorbed superheat will be continuously discharged for use, so that the contact area of ​​the smoke can be increased through the inclined box 21 and the vertical box 12, so that the cooling efficiency can be improved, thereby improving the effect of the water-cooled wall in a limited space. Each vertical box 12 is provided with a connecting block 9 on the several vertical boxes 12 in the middle, and a slot 35 is provided on the right side of each connecting block 9.

Each oblique box 21 is movably connected to a sleeve box 11, and a plurality of protrusions 23 are fixedly installed on the lower side of each sleeve box 11. Through each connecting block 9 and the square plate 34, the smoke moving to the right can be intercepted, thereby connecting the connecting block 9 and the anti-smoke provided on the square plate 34. The fire mud can intercept the heat generated by the impact of the flue gas, and it is convenient for users to disassemble the connecting block 9 and the square plate 34, so that users can replace the fire mud conveniently to avoid cracks caused by long-term use of the fire mud and affect the effect. At the same time, the surface of the sleeve 11 can be coated with fire mud, and the surface of the sleeve 11 can be made rough by the protrusion 23, so that the particles in the passing flue gas can be attached to the fire mud on the sleeve 11. In this way, after using it for a period of time, the sleeve 11 can be pulled out to replace the fire mud and clean the particles in the flue gas at the same time. A connecting box 17 is provided between each vertical box 12.Each connecting box 17 is fixedly connected to the left side of the wall panel 1, and each connecting box 17 is tilted.

Each small tube 18 is fixedly connected to each vertical box 12 respectively. The vertical boxes 12 can be connected in pairs through the small tubes 18 on the connecting boxes 17. This can promote the interaction of water in each vertical box 12. At the same time, the upward moving flue gas can be guided by the tilted setting of the connecting box 17, and the flue gas can be cooled at the same time, thereby further improving the effect of the water-cooled wall. A round box 6 is fixedly sleeved on the horizontal tube 7, and a movable circular plate 38 is movably connected in the circular box 6. A movable column 4 is fixedly installed on the rear side of the movable circular plate 38 0, the moving column 40 is movably connected to the cross tube 7, and two pressure springs 36 are fixedly installed on the front of the moving circular plate 38. The front end of each pressure spring 36 is fixedly connected to the front inner wall of the round box 6. Through the round box 6 and the pressure spring 36, when the pressure of the water in the water-cooled wall is too high due to the high temperature, the water pressure will drive the moving column 40 to move forward, thereby driving the moving circular plate 38 to move forward, so that the pressure can be relieved, thereby avoiding the internal pipe from bursting. A circular groove 22 is provided on the moving column 40, and a pressure relief circular box 39 is movably connected in the circular groove 22. The side wall of the pressure relief circular box 39 is provided with two notches 37, and the inner wall of the circular groove 22 is provided with an annular wall groove 41. A sealing tube 42 is fixedly installed in the annular wall groove 41, and the sealing tube 42 is movably connected The movable sleeve is connected to the pressure relief round box 39. The pressure relief round box 39 has no front wall. The pressure relief round box 39 is fixed through the front wall of the round box 6. When the water in the water-cooled wall generates excessive pressure due to the high temperature, the movable column 40 moves forward. When the pressure continues to increase, the movable column 40 will continue to move forward. When the movable column 40 moves to the front of the two notches 37, the water in the water-cooled wall will enter the pressure relief round box 39 through the two notches 37, so that the water will be discharged through the pressure relief round box 39. In this way, the pressure can be further relieved to avoid pipe bursting. When the pressure relief is completed, the rebound of the pressure spring 36 will drive the movable column 40 to return to its original position. A shielding pipe 4 is fixedly installed on the front side of the round box 6. A baffle 3 is fixedly installed on the front side of the shielding pipe 4. A water outlet 43 is provided on the side wall of the shielding pipe 4. , a collecting box 2 is provided under the shielding pipe 4, an arc-shaped groove 5 is provided on the upper side of the collecting box 2, a long groove 24 is provided on the front wall of the collecting box 2, a transparent strip 25 is fixedly installed in the long groove 24, a buoyancy plate 27 is movably connected in the collecting box 2, and a number of water-permeable grooves 26 are provided on the buoyancy plate 27. After the collecting box 2 is pushed under the shielding pipe 4, when the pressure in the water-cooled wall is too high, the water discharged from the pressure relief box 39 will impact the baffle 3, and then the water will be blocked by the shielding pipe 4, so that the water can only be discharged into 2 through the water outlet 43, so that the discharged water will be recycled and reused, and at the same time, it is prevented from being scalded by splashing water. The transparent strip 25 can penetrate the position of the internal buoyancy plate 27, so that the amount of water collected in the collecting box 2 can be judged by the position of the buoyancy plate 27.Each inclined box 21 is fixedly mounted with mounting plates 32 on both sides, each mounting plate 32 has a groove 30, each mounting plate 32 has a small slot 28, each small slot 28 has a bolt 29 movably passed through it, each bolt 29 has a fixing plate 31 threadedly sleeved on it, and each fixing plate 31 is fixedly connected to each vertical box 12. Each sleeve box 11 is fixedly mounted with connecting strips 20 on both sides, each connecting strip 20 has a shielding slot 44. The inclined box 21 can be installed and removed by means of the mounting plates 32, bolts 29 and fixing plates 31. When the device has been used for a long time, the inclined box 21 can be removed and then a tool can be inserted into the vertical box 12 through the through slot 33 to clean the internal scale and other impurities. The bolts 29 and mounting plates 32 can be protected by the connecting strips 20.

[0032] During use, the first step is: after connecting the horizontal pipe 7 and the short pipe 15 to the water pipe, water can be injected into it from one of them, so that the water will enter the several vertical pipes 13 and each vertical box 12, and as the water is continuously injected, the water will flow in the dry vertical pipes 13 and each vertical box 12 and each inclined box 21, and then the guide frame 8 on the device is set at the smoke outlet, so that the hot smoke will enter the guide frame 8, and then the smoke will flow upward along the several vertical boxes 12, and thus the smoke will flow upward along each inclined box 21, so that it will be cooled by the water flowing in the inclined box 21, the vertical box 12 and the vertical pipe 13 in the wall panel 1, and at the same time, the water that has absorbed superheat will be continuously discharged for utilization, so that the contact area of ​​the smoke can be increased through the inclined box 21 and the vertical box 12, so that the cooling efficiency can be improved, thereby improving the effect of the water-cooled wall in a limited space.

[0033] Step 2: Each connecting block 9 and square plate 34 can be used to intercept the smoke moving to the right, so that by setting fireproof mud on the connecting block 9 and the square plate 34, the heat generated by the impact of the smoke can be intercepted. At the same time, it is convenient for users to disassemble the connecting block 9 and the square plate 34, so that users can replace the fireproof mud conveniently to avoid cracks caused by long-term use of the fireproof mud and affect the effect. At the same time, the surface of the box 11 can be coated with fireproof mud, and the surface of the box 11 can be made rough through the protrusion 23, so that the particles in the passing smoke can adhere to the fireproof mud on the box 11. In this way, after using it for a period of time, the box 11 can be pulled out to clean the particles in the smoke while replacing the fireproof mud.

[0034] Step 3: Each vertical box 12 can be connected in pairs through the small tube 18 on the connecting box 17, so as to promote the interaction of water in each vertical box 12. At the same time, the upward moving flue gas can be guided by the inclined setting of the connecting box 17, and the flue gas can be cooled, thereby further improving the effect of the water-cooled wall.

[0035] Step 4: Through the round box 6 and the pressure spring 36, when the water in the water-cooled wall generates too much pressure due to the high temperature, the water pressure will drive the movable column 40 to move forward, thereby driving the circular plate 38 to move forward, so that the pressure can be relieved, thereby avoiding the internal pipe from bursting.

[0036] Step 5: When the moving column 40 is driven forward by the excessive pressure generated by the high temperature of the water in the water-cooled wall, the moving column 40 will continue to move forward as the pressure continues to increase. When the moving column 40 moves in front of the two notches 37, the water in the water-cooled wall will enter the pressure relief box 39 through the two notches 37, and the water will be discharged through the pressure relief box 39. In this way, the pressure can be further relieved to avoid pipe burst. When the pressure relief is completed, the rebound of the pressure spring 36 will drive the moving column 40 to return to its original position.

[0037] Step 6: After pushing the collecting box 2 under the shielding tube 4, when the pressure inside the water-cooled wall is too high, the water discharged from the pressure relief box 39 will impact the baffle 3, and then the water will be blocked by the shielding tube 4, so that the water can only be discharged into 2 through the water outlet 43. The discharged water will be recycled and at the same time avoid splashing water to scald people. The transparent strip 25 can pass through the position of the internal buoyancy plate 27, so that the amount of water collected inside the collecting box 2 can be judged by the position of the buoyancy plate 27.

[0038] Step 7: The inclined box 21 can be installed and removed by using the mounting plate 32, bolts 29 and fixing plate 31. When the device has been used for a long time, the inclined box 21 can be removed and a tool can be inserted into the vertical box 12 through the through slot 33 to clean the internal scale and other impurities. The bolts 29 and the mounting plate 32 can be protected by the l8 connecting strip 20.
