Description

Technical Field

[0001] The invention relates to the field of gasifier leak plugging, and in particular to an online leak plugging device for gasifier knocker leakage. Background Art

[0002] Gasifier is a device that converts solid fuel or biomass into usable gas. It is widely used in chemical industry, power generation, metallurgy, biomass energy, environmental protection and many other fields. With the continuous development of science and technology and the improvement of energy and environmental protection requirements, the application prospects of gasifier will be broader. The main function of the gasifier knocker is to remove the ash on the internal parts. By knocking the heat exchange surface of the gasifier, the dry loose ash and the accumulated bonding ash attached to the inner wall of the gasifier are removed.

[0003] Gasifier knockers are widely used in industrial equipment such as coal gasifiers, effectively solving the problem of ash accumulation in gasifiers and improving the operating efficiency and stability of the equipment. In the prior art, with the frequent knocking of the knocker, cracks or pores will gradually appear on the gasifier body. These cracks and pores are usually caused by metal fatigue, stress concentration or material defects. Cracks and pores will cause the synthesis gas in the gasifier to leak into the air, forming a potential explosive mixture. When the leaked synthesis gas encounters open flames or high temperatures, it may explode, posing a serious threat to the safety of personnel and equipment. The expansion of the cracks may cause further damage to the gasifier body, or even rupture, requiring shutdown for maintenance, increasing maintenance costs and time. At the same time, the generation and development direction of cracks are very uncertain and difficult to predict, which makes it impossible for traditional plugging devices to accurately locate and plug cracks. Due to the unpredictability of the direction of the cracks, it is difficult for traditional plugging devices to plug leaks in a timely and effective manner, resulting in the continued existence of leakage problems. Cracks that are not plugged in time may expand rapidly, increasing the probability of accidents. Summary of the invention

[0021] like Figure 5 As shown, the plugging mechanism 8 includes a sealing module 801, in which a sealing liquid is stored. The sealing module 801 is fixedly connected to the upper surface of the support plate 10, and an injection tube 802 is fixedly connected to the upper surface of the sealing module 801. The injection tube 802 passes through the side of the plugging frame 604 and is located inside the plugging frame 604 in a spiral shape. The other end of the injection tube 802 is connected to the circular through hole on the arc-shaped side of the plugging head 12.

[0022] like Figure 4As shown, the cooling mechanism 9 includes a cooling module 901, and the cooling module 901 stores coolant inside. The cooling module 901 is fixedly connected to the upper surface of the support plate 10. The upper surface of the cooling module 901 is fixedly connected with a liquid inlet pipe 902, and the shape of the liquid inlet pipe 902 is spiral. A cooling pipe 904 is opened inside the side of the plugging frame 604, and the cooling pipe 904 is distributed in a serpentine shape in the plugging frame 604. The other end of the liquid inlet pipe 902 is fixedly connected to the cooling pipe 904, and the other end of the cooling pipe 904 is fixedly connected with a liquid outlet pipe 903, and the shape of the liquid outlet pipe 903 is spiral. The other end of the liquid outlet pipe 903 is fixedly connected to the cooling module 901. By setting the cooling mechanism 9, the location where cracks or pores occur in the gasifier 1 can be locally cooled so that the sealing liquid can be better sealed.

[0023] like Figure 1 , Figure 8 As shown, the upper surface of the support plate 10 is fixedly connected with a knocking bracket 13, and the knocking mechanism 4 includes a shell 408, which is fixedly connected to the knocking bracket 13.

A return spring 407 is fixedly connected between the piston 405 and the shell 408. The piston 405 is slidably connected to the shell 408, and the arc side of the shell 408 is fixedly connected with a degassing spring 407 through a thread. The silencer 403 is provided to eliminate the noise pollution caused by the movement of compressed air. The other end of the housing 408 is fixedly connected to a pressure plate 402 by a fixing bolt 404. The other side of the pressure plate 402 is fixedly connected to two air pipe joints 401 by threads. An arrow-shaped groove is provided on the side of the pressure plate 402 and on one side of one of the air pipe joints 401. The air pipe joint 401 is an air inlet. The knocking mechanism 4 is driven by air pressure. The air pressure can be adjusted according to the actual situation, thereby adjusting the knocking force of the knocking mechanism 4.

[0024] like Figure 1 , Fig.10 As shown, two T-shaped annular grooves are provided on the arc-shaped side of the gasifier 1, and the support plate 10 is slidably connected in the T-shaped annular groove on the lower side, so that the displacement mechanism 3 drives the support plate 10 to rotate around the gasifier 1. The lower end of the gasifier 1 is fixedly connected with a furnace body bracket 2. By setting the furnace body bracket 2, support is provided for the gasifier 1 to ensure the smooth operation of the gasifier 1.

[0025] like Fig. 9As shown, the displacement mechanism 3 includes a displacement sleeve 301, which is slidably connected in the T-shaped ring groove on the upper side of the gasifier 1, and one end of the displacement sleeve 301 is fixedly connected to a displacement motor 302, and the output end of the displacement motor 302 that passes through the support plate 10 is fixedly connected to a driving gear 303, and the arc-shaped outer side surface of the gasifier 1 is fixedly connected to a ring gear 304, and the driving gear 303 is meshingly connected with the ring gear 304. When the displacement motor 302 is started, the support plate 10 is driven to rotate around the gasifier 1 through the meshing connection of the driving gear 303 and the ring gear 304, so that the knocking mechanism 4 can evenly knock on the circumference of the gasifier 1.

[0026] like Figure 7 As shown, a one-way valve 11 is arranged on the side of the plugging frame 604. By arranging the one-way valve 11, the internal and external air pressures of the closed space of the plugging frame 604 are balanced to ensure the smooth operation of the plugging mechanism 6. The one-way valve 11 includes a valve body 1101, which is fixedly connected to the plugging frame 604. A circular through hole is opened on the side of the valve body 1101, and two baffles 1103 are fixedly connected at both ends of the circular through hole. A guide shaft 1106 is fixedly connected between the two baffles 1103. The inner side of the valve body 1101 is also fixedly connected to a limiting sleeve 1102, and a conical hole is opened on the inner side of the limiting sleeve 1102. The arc-shaped outer side of the guide shaft 1106 is slidably connected to the valve 1104. The valve 1104 is hemispherical, and a tension spring 1105 is fixedly connected between the side of the valve 1104 and the baffle 1103.

[0027] like Figure 1 As shown, the upper surface of the leak-plugging frame 604 is fixedly connected with a camera module 7. By setting the camera module 7, cracks and pores on the outside of the gasifier 1 are identified, and the data information is sent to the control module 5. The lower surface of the support plate 10 is fixedly connected with the control module 5. By setting the control module 5, the data information sent by the camera module 7 is processed, and the leak-plugging head 12 is adjusted to the position of the cracks and pores through the displacement mechanism 3 and the leak-plugging mechanism 6.

[0028] Working principle: When the device is used, the gasifier 1 converts solid fuel or biomass into usable gas, and the knocking mechanism 4 shakes off the ash attached to the inner wall of the gasifier 1. When cracks or pores appear on the outer wall of the gasifier 1 due to the knocking of the knocking mechanism 4, the camera module 7 captures and identifies the direction of the cracks or the position of the pores, and sends the data information to the control module 5. The control module 5 analyzes the data information and starts the displacement mechanism 3 to move the plugging mechanism 6 to the specified position. The control module 5 controls the plugging mechanism 6 to seal the leak to prevent the usable gas from escaping, and The plugging head 12 is aimed at the leaking crack or pore, the control module 5 starts the plugging mechanism 8 to spray the sealant from the plugging head 12 to the leaking place, the control module 5 starts the cooling mechanism 9 to cool the sealant at the leaking place to accelerate its solidification, and the one-way valve 11 adjusts the air pressure in the closed space at the leaking place to keep it balanced with the outside. When the crack or pore at the leaking place is sealed, the control module 5 resets the other mechanisms, and the gasifier 1 does not need to be shut down to seal the crack and pore, which shortens the maintenance cycle, improves production efficiency, and reduces equipment maintenance and operation costs.

[0029] When the knocking mechanism 4 shakes off the ash attached to the inner wall of the gasifier 1, compressed air enters the interior of the shell 408 from the air pipe joint 401 with an arrow-shaped slide groove on one side, and pushes the piston 405 to slide to the other side. The piston 405 slides to the other side to compress the reset spring 407. The piston 405 slides to the other side and pushes the knocking column 406 to slide to the other side. The knocking column 406 slides to the other side and hits the gasifier 1 to cause vibration, thereby shaking off the ash attached to the inner wall of the gasifier 1 to prevent ash accumulation and reduce the production efficiency of the gasifier 1. The compressed air is discharged from the other air pipe joint 401, and the reset spring 407 releases the pressure to push the piston 405 to reset. The reset of the piston 405 pulls the knocking column 406 to reset, and the muffler 403 filters the noise generated by the movement of the compressed air to reduce noise pollution.

[0030] When the displacement mechanism 3 is started to move the plugging mechanism 6 to the specified position, the displacement motor 302 is started, and the output end of the displacement motor 302 drives the driving gear 303 to rotate, and the driving gear 303 is meshed and connected with the ring gear 304. The driving gear 303 drives the support plate 10 to rotate around the gasification furnace 1, and the support plate 10 drives the plugging mechanism 6 to move to the specified position, so that the plugging head 12 can follow the direction of the crack to seal.

[0031] The control module 5 controls the leak-proof mechanism 6 to seal the leak, and when the leak-proof head 12 is aimed at the leak, the electric telescopic rod 602 is started, and the output end of the electric telescopic rod 602 pushes the connecting seat 603 to move toward the gasifier 1, and the connecting seat 603 moves toward the gasifier 1 to push the leak-proof frame 604 to move toward the gasifier 1, and the leak-proof frame 604 moves toward the gasifier 1 to drive the sealing ring 611 to move toward the gasifier 1, and after the sealing ring 611 contacts the gasifier 1, a closed space is formed between the leak-proof frame 604 and the gasifier 1, and the lifting motor 605 is started, and the output end of the lifting motor 605 drives the lifting shaft 606 to rotate, and the lifting shaft 606 rotates to drive the lifting plate 610 to move up and down, and the lifting plate 610 moves up and down to drive the leak-proof head 12 to move up and down, and translates The motor 607 is started, and the output end of the translation motor 607 drives the translation shaft 608 to rotate. The rotation of the translation shaft 608 drives the translation plate 609 to reciprocate left and right. The reciprocating movement of the translation plate 609 drives the plugging head 12 to reciprocate left and right. The movement of the translation plate 609 and the lifting plate 610 is controlled to drive the plugging head 12 to move to the leaking place. At this time, the plugging mechanism 6 aims the plugging head 12 at the cracks and pores, and the cracks and pores at the leaking place are blocked. During the blocking process, the control module 5 controls the rotation of the lifting motor 605 and the translation motor 607, so that the translation plate 609 and the lifting plate 610 move up, down, left and right, thereby driving the plugging head 12 to move according to the irregular direction of the cracks, thereby blocking the irregular direction of the cracks.

[0032] When the control module 5 starts the sealing mechanism 8 to spray the sealant from the plugging head 12 to the leaking place, the sealing module inputs the sealant into the injection tube 802, and the sealant flows through the injection tube 802 into the plugging head 12. The sealant is sprayed out from the circular hole of the plugging head 12 to seal the cracks or pores at the leaking place, so that the gasifier 1 does not need to be shut down to seal the leaking place, thereby shortening the maintenance cycle.

[0033] When the control module 5 starts the cooling mechanism 9 to cool down the sealant at the leaking location, the cooling module 901 transports the coolant to the liquid inlet pipe 902, and the coolant enters the cooling pipe 904 through the liquid inlet pipe 902. The coolant cools the leak-proof frame 604 and then cools and solidifies the sealant at the leaking location. The coolant flows from the cooling pipe 904 into the liquid outlet pipe 903, and the coolant flows back to the cooling module 901 from the liquid outlet pipe 903. This cycle is used to cool and solidify the sealant at the leaking location.

[0034] The one-way valve 11 adjusts the air pressure in the closed space at the leakage point to keep it balanced with the outside. When the air pressure in the closed space decreases, the tension spring 1105 contracts and pulls the valve 1104 to slide to one side. The valve 1104 slides to one side and loses contact with the limiting sleeve 1102. At this time, external air can enter the closed space, and the air pressure inside and outside the leak-proof frame 604 remains balanced. When the air pressure in the closed space is high, the air pressure pushes the valve 1104 to slide to the other side. The valve 1104 slides to the other side and stretches the tension spring 1105. The valve 1104 slides to the other side and contacts with the limiting sleeve 1102 to prevent the internal gas from escaping. The leaked gas in the gasifier 1 is high-temperature and high-pressure gas. After being cooled by the cooling mechanism 9, the internal air pressure will gradually decrease. The one-way valve 11 keeps the internal and external air pressure balanced, which is convenient for resetting the leak-proof mechanism 6.

[0035] The above-mentioned embodiments only express the preferred implementation modes of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person skilled in the art, several modifications, improvements and substitutions can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention patent shall be subject to the attached claims.
