Description

Technical Field

[0001] The invention relates to the field of vibration dust removal devices, and in particular to a multi-stage sealed vibration dust removal device. Background Art

[0002] In the late 1990s, dry coal powder gasification technology was favored by many domestic coal chemical companies because of its advantages of significantly improving coal utilization and reducing production costs. However, high-temperature gasifier water-cooled wall ash removal is a difficult issue. A large amount of dust produced by coal gasification is very easy to adhere to the water-cooled wall of the gasifier, greatly reducing the heat transfer efficiency, causing the gasifier outlet temperature to rise sharply, and even causing the entire system to automatically stop. The vibrating ash removal device used in the dry coal powder gasification process is a key device to ensure the normal operation of the coal gasification equipment. The vibrating ash removal device, also commonly known as a mechanical vibrator, is generally arranged at various angles around the gasifier, and it vibrates and knocks regularly to vibrate the vibrating surface, thereby playing the role of vibrating ash removal and ensuring the stable operation of the gasifier.

[0003] The operating environment of the mechanical vibrator is complex, and the sealing performance of its moving components is crucial. The quality of the sealing will directly affect whether the vibration dust removal device can operate smoothly. The key sealing technology of the vibration dust removal device is the sealing technology of the piston rod and the circumference of the piston that transmits the energy of the impact rod. In the prior art, the impact rod of the mechanical vibrator and the cylinder transmission rod are generally designed as one body, and the two complete the vibration action through large-scale reciprocating motion. This kind of mechanical vibrator has a strong vibration force and relatively clean ash cleaning, but the impact force and the impact cycle cannot be controlled during use. The mechanical vibrator is easy to damage, and the gasifier must be stopped for maintenance. The process is cumbersome and the economic consumption is large. On the other hand, since the mechanical vibrator mainly works in harsh environments such as high temperature and high pressure, dusty media, etc., it is more difficult to achieve good sealing of the large-scale reciprocating motion components of the piston rod, and it is often unable to be used because it cannot meet the sealing requirements.

[0004] Different from the above mechanical rappers, there is a mechanical rapper that uses a cylinder as a power source and completes the rapping through a piston, a piston rod and a percussion rod. The mechanical rapper performs linear motion through the rapping parts, has a strong rapping force, and the cylinder is a controllable device with simple and accurate control. It can be used in high temperature and high pressure environments, but the sealing structure is often severely damaged during use, which often causes the gasifier to be shut down for maintenance, resulting in poor economic benefits and large economic losses.

[0005] For example, Chinese patent CN100525925C discloses a mechanical vibrator, which is mainly composed of four parts: vibrating parts, seals, filter elements and supporting connectors. Its working principle is: kinetic energy is emitted from the cylinder to impact the piston rod, and the piston rod transfers the kinetic energy to the impact rod, which impacts the gasification equipment to achieve the purpose of removing dust accumulation and maintaining heat transfer efficiency. Figure 1 As shown, a sealing gasket is placed between the piston guide cylinder 24 and the conduit 26 of the mechanical rapper and then connected with bolts. The positioning bracket 4 is connected to the piston guide cylinder 24 by bolts 8. The piston guide cylinder 24 is connected by stud bolts 11 with nuts 12, stop washers and convex flanges 16. The convex flange 16 is connected to the corresponding convex flange on the gasification equipment by stud bolts 21 with nuts 22 and stop washers 23. However, this type of static seal is still not suitable for use in high temperature, high pressure, and dusty media environments. During use, the friction loss of kinetic energy conduction continues to increase, which easily causes damage to the sealing components, thereby increasing the maintenance cost.

[0006] Therefore, it is an urgent problem to develop a vibrating dust removal device with controllable vibration intensity, improved sealing effect, and meeting the dust removal requirements of high-pressure equipment, while extending the life of the sealing component and reducing maintenance costs. Summary of the invention

[0007] In view of the shortcomings of existing vibrating ash removal devices, such as easy leakage and short service life, the present invention provides a vibrating ash removal device, which integrates the advantages of vibrating ash removal, namely, controllable vibration intensity and good ash removal effect, and improves the sealing effect by arranging multi-stage sealing components in different combinations. In addition, when the sealing is good, the internal parts of the vibrating ash removal device can be replaced and repaired without stopping the gasification furnace.

[0008] The technical solution of the present invention is as follows:

[0009] A vibrating dust removal device comprises a fixedly connected high-pressure pneumatic section and a vibrating section.

[0010] The high-pressure pneumatic section is used to provide a closed high-pressure environment, so that the cylinder in the closed high-pressure environment provides kinetic energy through the piston, thereby doing work on the vibration section;

[0011] The vibration section is used to conduct the kinetic energy released by the high-pressure pneumatic section and impact the internal parts of the gasifier, thereby vibrating and removing ash from the inner wall of the gasifier.

[0012] Furthermore, the vibrating dust removal device further comprises a cut-off flange 13 and a raised-face flange 16 , the high-pressure pneumatic section is connected to the cut-off flange 13 by bolts, and the vibrating section is connected to the raised-face flange 16 by welding.

[0013] Furthermore, the cut-off flange 13 is connected to the raised face flange 16 via bolts 14 , nuts 10 , stop washers 11 and metal wound washers 15 .

[0014] Furthermore, the vibrating ash removal device is connected to the corresponding raised face flange on the outer cylinder wall of the gasifier through a stud 17, a metal winding gasket 18, a stop gasket 19 and a nut 20.

[0015] Furthermore, the high-pressure pneumatic section includes a cylinder 1 and a cylinder bracket 4, wherein the cylinder 1 is fixedly connected to one end of the cylinder bracket 4, and the other end of the cylinder bracket 4 is connected to the cut-off flange 13 by bolts.

[0016] Furthermore, the other end of the cylinder bracket 4 is connected to the cut-off flange 13 through a nut 6 , a stop washer 7 and a bolt 8 .

[0017] Furthermore, the vibration section includes a conduit 29, an impact rod 28, a conical impactor 25, a conductive rod 9 and a spring 21, the conduit 29 is sleeved on the impact rod 28, the conical impactor 25 and the spring 21, the two ends of the conical impactor 25 are respectively abutted against one end of the impact rod 28 and the spring 21, and the other end of the impact rod 28 extends out of the conduit and contacts the internal parts of the gasifier; the conical impactor 25 is sleeved on the conductive rod 9, one end of the conductive rod 9 is fitted with the inside of the conical impactor 25, and the other end of the conductive rod 9 passes through the inner hole of the cut-off flange 13 and extends into the cylinder bracket of the high-pressure pneumatic section.

[0018] Furthermore, a positioning ring 5 is installed at the other end of the conductive rod 9 for observing the movement of the conductive rod 9 so as to understand the deformation of the impacted part in the gasifier during long-term operation.

[0019] Furthermore, the material of the impact rod 28 and the conductive rod 9 is precipitation hardened nickel-chromium-iron alloy Inconel718.

[0020] Further, the conical impactor 25 comprises a straight section of a cylinder and a head of a cone, the straight section of the cylinder is sleeved on the conductive rod 9, and the head of the cone fits the impact rod 28. The conical impactor 25 provides support and protection for the conductive rod 9. Further, the material of the conical impactor 25 is carbon steel.

[0021] Furthermore, the vibration section also includes a guide tube 30, a bearing sleeve 26 and a dustproof sealing ring 27 arranged in the groove of the bearing sleeve 26, the guide tube 30 is nested between the front end of the guide tube 29 and the impact rod 28, the bearing sleeve 26 is nested between the middle part of the guide tube 29 and the impact rod 28, the guide tube 30 and the bearing sleeve 26 are used to provide support and guiding functions for the impact rod 28, and at the same time, the bearing sleeve 26 and the dustproof sealing ring 27 are the first-level sealing components.

[0022] Furthermore, the material of the bearing sleeve 26 is precipitation hardened nickel-chromium-iron alloy Inconel 718, and the material of the dustproof seal ring 27 is high-hardness polyurethane.

[0023] Furthermore, the vibration section further includes an impactor sleeve 22 and a first sealing ring 23, wherein the impactor sleeve 22 and the first sealing ring 23 are nested between the guide tube 30 and the conical impactor 25, one end of the impactor sleeve 22 abuts against the bearing sleeve 26, and the other end extends and bends between the connection interface of the cut-off flange 13 and the raised face flange 16. The impactor sleeve 22 and the first sealing ring 23 are a second-stage sealing component.

[0024] Furthermore, the material of the impactor sleeve 22 is alloy steel, and the material of the first sealing ring 23 is hard graphite.

[0025] Furthermore, the inner groove of the cut-off flange 13 is further provided with a second sealing ring 12, and the second sealing ring 12 is nested between the inner hole of the cut-off flange 13 and the conductive rod 9. The cut-off flange 13 and the second sealing ring 12 form a third-level sealing component.

[0026] Furthermore, the material of the second sealing ring 12 is hard graphite.

[0027] Furthermore, the vibrating dust removal device also includes a gas pressure control system 31 for implementing gas protection for the vibrating dust removal device.

[0028] Furthermore, the air pressure control system 31 includes a pressure sensor, an electronic controller 32 and a high-pressure gas delivery device. When the vibrating ash removal device is working normally, the air pressure control system 31 plays a role of pressure monitoring; when the internal pressure of the vibrating ash removal device changes, the electronic controller 32 receives the value of the pressure sensor and starts the high-pressure gas delivery device to introduce an inert protective gas 0.1 to 0.3 MPa higher than the working pressure of the gasifier for protection. The air pressure control system 31 also plays a role in extending the life of the sealing component. For example, when the first-level seal fails, the high-pressure gas delivery device starts to work. Due to the extra layer of gas sealing protection, the life of the second-level seal and the third-level seal components will also be correspondingly increased.

[0029] Furthermore, in the air pressure control system 31, there are two pressure sensors, which are respectively arranged in the impactor sleeve 22 and the air inlet. Among them, the pressure sensor arranged in the impactor sleeve 22 is used to measure the pressure value at the gap between the impactor sleeve 22 and the conical impactor 25 close to the impact rod 28; the other pressure sensor arranged at the air inlet is used to measure the pressure value of the inert gas introduced from the air inlet. When the first-stage sealing assembly fails or both the first-stage and second-stage sealing assemblies fail, at this time, the pressure value measured between the impactor sleeve 22 and the conical impactor 25 is greater than the pressure value measured by the pressure sensor arranged at the air inlet, and the electronic controller 32 starts the high-pressure gas delivery device to supplement the pressure of the vibration dust removal device by inputting a certain amount of inert gas into the air inlet.

[0030] The present invention also provides a method for using the vibrating dust removal device, which comprises:

[0031] The cylinder in the high-pressure pneumatic section impacts the conductive rod and the conical impactor in the vibration section through the piston. The conductive rod and the conical impactor drive the impact rod in the vibration section to vibrate at high frequency under the action of the compression spring. The impact rod contacts various angles around the gasifier, and continuously vibrates and strikes in a regular pattern to vibrate the vibration surface, thereby achieving the effect of vibration and ash removal, thereby ensuring the stable operation of the gasifier.

[0032] The technical solution provided by the present invention may include the following beneficial effects:

[0033] 1. When the vibrating ash removal device of the present invention is working, kinetic energy is generated by the cylinder 1 in the high-pressure pneumatic section, and is transmitted through the conductive rod 9 and the conical impactor 25 in the vibration section, and finally the impact rod 28 transmits the kinetic energy to the internal parts of the gasifier, generating vibration and realizing the ash removal function. Among them, since the spring 21 is always in a compressed state, it pushes the conical impactor 25 forward, and the conical impactor 25 pushes the impact rod 28 forward, so the spring 21 in the compressed state makes the three fit closely, realizing the zero-distance contact between the conical impactor 25 and the impact rod 28 and the internal parts of the gasifier, ensuring the continuity of the impact.

[0034] 2. In the vibrating dust removal device of the present invention, the conical impactor 25 provides support and protection for the conductive rod 9; the guide tube 30 and the bearing sleeve 26 are used to provide support and guidance for the impact rod 28; the guide tube 30, the bearing sleeve 26 and the conical impactor 25 ensure the axial unity of the impact rod 28 and the conductive rod 9.

[0035] 3. Compared with the prior art, the vibration dust removal device of the present invention significantly improves the sealing effect through the combination of multi-stage sealing components. The first-stage sealing component is a combination of a bearing sleeve 26 and a dustproof sealing ring 27, the second-stage sealing component is a combination of an impactor sleeve 22 and a first sealing ring 23, and the third-stage seal is a combination of a cut-off flange 13 and a second sealing ring 12. The first-stage sealing component and the second-stage sealing component protect the sealing of the third-stage sealing component step by step. When the first-stage sealing component fails or both the first-stage sealing component and the second-stage sealing component fail, the good sealing of the third-stage sealing component can still ensure the normal operation of the entire vibration dust removal device, thereby preventing the gas in the gasification furnace from leaking to the connection between the cut-off flange 13 and the cylinder 1, causing damage to the vibration dust removal device. Therefore, the combination of the multi-stage sealing components of the present invention greatly improves the operating efficiency and operating time of the vibration dust removal device, extends the life of the entire sealing system, and reduces maintenance costs.

[0036] 4. The combination of the multi-stage sealing components of the present invention also ensures that the entire sealing system is well sealed, and the conductive rod 9 and the cylinder 1 can be replaced or repaired separately without stopping the gasifier, thereby improving production efficiency. For example, when the first and second stage sealing components fail and the third stage sealing components are well sealed, the cylinder 1 can be unloaded and replaced and repaired separately; when the first stage sealing component fails and the second and third stage sealing components are well sealed, the conductive rod 9 can be unloaded and replaced and repaired.

[0037] 5. The air pressure control system of the present invention provides additional air sealing protection for the vibrating dust removal device by real-time monitoring and regulating the pressure inside the vibrating dust removal device, and also serves to increase the service life of the second-stage and third-stage sealing components.

[0038] 6. The vibrating ash removal device of the present invention has a simple structure, an obvious ash removal effect, a long service life, and can be applied to ash removal work in various harsh working conditions such as high temperature and high pressure. This invention makes up for the problem that other ash removal devices cannot be used in high temperature and high pressure environments or have leakage problems during ash removal by vibration, and can greatly meet the ash removal requirements of the gasifier.

[0055] A positioning ring 5 is installed at the other end of the conductive rod 9 for observing the movement of the conductive rod 9 so as to understand the deformation of the impacted part in the gasifier during long-term operation.

[0056] The material of the striking rod 28 and the conducting rod 9 is inconel 718, a precipitation hardening nickel-chromium-iron alloy.

[0057] The conical impactor 25 includes a straight section of a cylinder and a conical head, the straight section of the cylinder is sleeved on the conductive rod 9, and the conical head fits the impact rod 28. The conical impactor 25 provides support and protection for the conductive rod 9. The material of the conical impactor 25 is carbon steel.

[0058] A liner 24 is nested between the conical impactor 25 and the conductive rod 9 to support the conductive rod 9 .

[0059] The vibration section also includes a guide tube 30, a bearing sleeve 26 and a dustproof sealing ring 27 arranged in the groove of the bearing sleeve 26. The guide tube 30 is nested between the front end of the guide tube 29 and the impact rod 28, and the bearing sleeve 26 is nested between the middle part of the guide tube 29 and the impact rod 28. The guide tube 30 and the bearing sleeve 26 are used to provide support and guiding functions for the impact rod 28. At the same time, the bearing sleeve 26 and the dustproof sealing ring 27 are the first-level sealing components.

[0061] The vibration section also includes an impactor sleeve 22 and a first sealing ring 23, which are nested between the guide tube 30 and the conical impactor 25. One end of the impactor sleeve 22 abuts against the bearing sleeve 26, and the other end extends and bends between the connection interface of the cut-off flange 13 and the raised face flange 16. The impactor sleeve 22 and the first sealing ring 23 are the second-stage sealing components.

[0062] The material of the impactor sleeve 22 is alloy steel, and the material of the first sealing ring 23 is hard graphite.

[0064] The material of the second sealing ring 12 is hard graphite.
