Description

Technical Field

[0001] The invention relates to the field of vibration dust removal devices, and in particular to a high-pressure resistant 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, extended service life of seals, met the dust removal requirements of high-voltage equipment, and reduced maintenance costs. Summary of the invention

[0007] In view of the shortcomings of existing vibrating dust removal devices, such as easy leakage and short service life, the present invention provides a high-pressure resistant vibrating dust removal device, which integrates the advantages of vibrating dust removal, namely, controllable vibration intensity and good dust removal effect. At the same time, the cylinder is placed in a closed high-pressure environment, which completely solves the leakage problem and extends the service life of the seal.

[0017] Furthermore, the other end of the cylinder bracket 7 is connected to the socket welding flange 15 through a stud 13 , a stop washer 12 and a nut 11 .

[0018] Furthermore, the first high-pressure gas input port 4 is connected to the gas path A, and the external high-pressure gas input device introduces high-pressure gas into the pressure-bearing outer cylinder 1 through the gas path A, so that the inside of the pressure-bearing outer cylinder 1 maintains a high-pressure environment.

[0019] Furthermore, the outer wall of the pressure-bearing outer cylinder 1 is also provided with a second high-pressure gas input port 5, and the second high-pressure gas input port 5 is connected to the gas path B, and the gas path B passes through the pressure-bearing outer cylinder 1 and is connected to the cylinder 6. Through the gas path B, an external high-pressure gas input device allows high-pressure gas to be introduced into the cylinder 6.

[0020] Furthermore, the pressure of the gas circuit B is 0.5-0.7 MPa higher than the pressure of the gas circuit A, so that the working pressure in the cylinder 6 is higher than the pressure in the pressure-bearing outer cylinder 1 .

[0021] Furthermore, the gas introduced into the pressure-bearing outer cylinder 1 through the gas path A is nitrogen or carbon dioxide, and the gas introduced into the cylinder 6 through the gas path B is nitrogen.

[0022] Furthermore, the transmission section includes a connecting pipe 21, a sleeve 20, a transmission rod 19, a first bushing 22 and a spring 18, wherein the connecting pipe 21 is sleeved on the sleeve 20 and the spring, the sleeve 20 is sleeved on the transmission rod 19, the first bushing 22 is nested in the corresponding groove of the sleeve 20, and one end of the transmission rod 19 passes through the inner hole of the socket welding flange 15 and extends into the cylinder bracket of the high-pressure pneumatic section.

[0023] Furthermore, a second bushing 14 is nested in the socket welding flange 15 and the transmission rod 19 .

[0024] Furthermore, the rapping section includes a conduit 27, a guide ring 28, an impact rod 29 and a guide tube 30, wherein the guide ring 28, the impact rod 29 and the guide tube 30 are installed inside the conduit 27, the guide tube 30 and the guide ring 28 are respectively nested at the front and rear ends between the conduit 27 and the impact rod 29, one end of the impact rod 29 is abutted against the other end of the transmission rod 19, and the other end of the impact rod 29 extends out of the conduit and contacts the internal parts of the gasifier.

[0025] Furthermore, the high-pressure resistant vibrating dust removal device is also provided with a pressure sensor 3 and an electrical signal output terminal 2. The pressure sensor 3 is installed on the outer wall of the pressure-bearing outer cylinder 1, and the electrical signal output terminal 2 passes through the pressure-bearing outer cylinder 1 and is connected to the cylinder 6. The pressure sensor 3 and the electrical signal output terminal 2 are used to monitor the pressure in the cylinder 6 and the pressure-bearing outer cylinder 1 in real time and transmit the detected pressure data to an external pressure detection device, thereby adjusting the gas source pressure to achieve the above-mentioned gas circuit pressure control requirements.

[0026] Furthermore, the joint where the line of the electrical signal output terminal passes through the outer shell of the pressure-bearing outer cylinder 1 is sealed by sintered metal ceramics or volcanic rock.

[0027] The present invention also provides a method for using the vibrating dust removal device, which comprises:

[0028] The cylinder in the high-pressure pneumatic section impacts the transmission rod in the transmission section through the piston. Under the action of the spring, the transmission rod drives the impact rod in the rapping section to vibrate at a high frequency. The impact rod contacts various angles around the gasifier, and continuously raps and strikes according to a regular pattern to vibrate the rapping surface, thereby achieving the effect of rapping and removing ash, thereby ensuring the stable operation of the gasifier.

[0029] The technical solution provided by the present invention may include the following beneficial effects:

[0030] 1. When the high-pressure vibration ash removal device of the present invention is working, kinetic energy is generated by the high-pressure cylinder 6 in the high-pressure pneumatic section, and is transmitted through the transmission rod 19 in the transmission section, and finally the impact rod 29 in the rapping section transfers the kinetic energy to the gasifier internals to generate vibration, thereby realizing the ash removal function. Among them, the function of the spring 18 is to keep the sleeve 20, the transmission rod 19, the impact rod 29 and the inside of the gasifier in close contact, and the spring 18 is always in a compressed state to ensure the continuity of the impact.

[0031] 2. The high-pressure vibration dust removal device of the present invention is connected together by a second plate-type flat welding flange 26, a first plate-type flat welding flange 17 and a socket welding flange 15 by means of studs, nuts, sealing gaskets and welding processes, so that the high-pressure pneumatic section, the transmission section and the rapping section form an integral sealing structure, overcoming the defect in the prior art that the piston rod and the piston circumference, i.e., the transmission rod and the sleeve of the present invention, are not easy to seal.

[0032] 3. In the high-pressure vibration dust removal device of the present invention, the guide tube 27, the sleeve 20 and the first bushing 22 play a role in supporting and guiding the transmission rod 19 and the impact rod 29; in addition, the transmission rod 19 and the impact rod 29 are ensured to have a unified axial position through the guide tube 30, the guide ring 28, the first bushing 22 and the sleeve 20.

[0033] 4. The present invention places the cylinder 6 inside the pressure-bearing outer cylinder 1, and through real-time monitoring of the pressure sensor 3 and regulation of the gas source pressure, the pressure of the pressure-bearing outer cylinder 1 is kept in pressure balance with the pressure of the gasifier, and at the same time, the pressure inside the pressure-bearing outer cylinder 1 is kept 0.5-0.7MPa less than the pressure of the cylinder 6, so that the cylinder 6 always works in a pressure environment with a pressure difference of +0.5-0.7MPa, thus completely solving the leakage problem. Since the high-pressure vibration dust removal device of the present invention no longer uses multi-stage sealing rings for high-pressure sealing, the sealing component has a simple structure, so the friction loss of kinetic energy conduction is reduced, the utilization efficiency of the energy transmission process is increased, and the number of times the sealing element is damaged due to friction and thus stopped for maintenance is reduced, thereby reducing the maintenance cost.

[0034] 5. The high-pressure vibration dust removal device of the present invention has a simple structure, an obvious dust removal effect, a long service life, and can be applied to dust removal work in various harsh working conditions such as high temperature and high pressure. This invention makes up for the problem that other dust removal devices cannot be used in high temperature and high pressure environments or have leakage problems due to vibration dust removal, and can greatly meet the dust removal requirements of gasification devices.
