Description

Technical Field

[0001] The utility model relates to the technical field of dust removal devices, in particular to an installation structure of a pulse dust removal device. Background Art

[0002] In recent years, incineration power generation has become the most effective way to treat urban domestic waste in a "harmless, reduced, and resource-based" manner. According to the waste incineration process, toxic gases such as sulfur dioxide and dioxins will be produced during the incineration process, as well as a large amount of high-temperature smoke. The pulse dust collector is the most widely used dust collector equipment and is also the most commonly used dust collector in waste incinerators. According to data, the main dust removal equipment in my country's operating waste incineration power plants is the pulse dust collector. During the use of the pulse dust collector, the dust accumulated on the surface of the filter element will continue to increase, which will increase the operating resistance of the equipment accordingly. In order to ensure the normal operation of the system, it is necessary to use a pulse dust removal device regularly for cleaning to achieve the purpose of reducing equipment resistance.

[0003] The operation and maintenance costs of the pulse dust collector are important factors to consider its performance. The key component of the pulse dust collector is the filter element. The cage frame, as the supporting component of the filter element, is an important component of the pulse dust collector. Due to the short life of the filter element, especially the filter element at high temperature and the working conditions of highly corrosive flue gas, some need to be replaced in just a few months. The installation and maintenance of the pulse dust collector in the prior art after the filter element expires is relatively complicated. To solve this problem, an oblique drawer-type pulse dust collector came into being, and patent 202121191412.X discloses an oblique drawer-type pulse dust collector structure. However, in this technical solution, the pulse dust removal device adopts a built-in structure, which is inconvenient to install, inspect and maintain. Utility Model Content

[0004] The utility model aims to provide a pulse dust removal device installation structure to solve the problems existing in the prior art.

[0005] The purpose of the utility model is achieved as follows: A pulse dust removal device installation structure, including an air distribution bag and a blowing pipe, the air distribution bag is installed on the outside of the pulse dust collector, the top of the air distribution bag is connected to the air storage bag through an air supply pipe, the air supply pipe is provided with a pulse control valve, connecting short pipes are distributed on the air distribution bag, the blowing pipe and the connecting short pipe are connected through a switching elbow, and plug-in connectors are provided at both connecting ends of the switching elbow, the connecting ends of the blowing pipe and the connecting short pipe are provided with a plug-in socket matched with the plug-in socket, the plug-in socket is provided with convex ridges, and the plug-in socket is provided with a long groove matched with the convex ridges, the end of the blowing pipe is plugged into the pulse dust collector, and a positioning notch is provided on the outer side of the pipe wall of the blowing pipe corresponding to the plug-in position and a sealing plate is installed, the sealing plate includes two butt-jointed base plates, the base plate is provided with a connecting seat, the connecting seat is provided with a connecting hole and is connected by connecting bolts.

[0006] The installation structure of the pulse dust removal device of the utility model adopts a detachable connection structure between each component, which is convenient for installation and disassembly maintenance. For example, if a certain adapter elbow needs to be replaced, it is only necessary to remove the sealing plate on the blow pipe connected thereto, and then pull out the blow pipe to release the connection between the blow pipe and the adapter elbow (at this time, the blow pipe is still plugged into the pulse dust collector, but the insertion depth is deeper. In order to prevent the blow pipe from sliding into the pulse dust collector, the installation holes on the pulse dust collector can also be plugged with cloth balls, etc.) Finally, the adapter elbow to be replaced is pulled out from the connecting short pipe and a new adapter elbow is installed. After the installation is completed, the blow pipe is plugged into the adapter elbow and the sealing plate is installed. The whole process is fast and efficient, which greatly improves the maintenance efficiency. At the same time, the design of the sealing plate and the positioning notch can reduce the requirements for the size of the blow pipe on the pulse dust collector, the length of the connecting short pipe, the plug-in depth of the plug connector and the plug socket, the straightness of the blow pipe, etc., while achieving a good sealing of the clean air chamber of the pulse dust collector, thereby reducing the manufacturing cost. In summary, the pulse dust removal device installation structure of the utility model has the advantages of convenient and quick disassembly and maintenance, low manufacturing cost, etc.

[0007] As a further improvement of the utility model, the pulse dust collector is provided with a mounting hole corresponding to the insertion position of the blowing pipe, the diameter of the mounting hole is larger than the outer diameter of the blowing pipe, and a sealing gasket is clamped on the joint surface of the substrate, so as to reduce the requirements for the machining accuracy of parts and maximize the sealing effect.

[0008] As a further improvement of the utility model, a support frame is welded and fixed to the outer wall of the pulse dust collector corresponding to the lower edge of the base plate to prevent vibration and noise at the end of the blowing pipe during the blowing operation or deformation of the end due to lack of support after long-term use.

[0009] As a further improvement of the utility model, a filter cartridge is arranged obliquely in the pulse dust collector, and the blowing pipe is arranged obliquely corresponding to the axial direction of each filter cartridge to achieve the best blowing and cleaning effect.

[0010] As a further improvement of the utility model, the thickness of the blowing tube is not less than 8 mm, so as to avoid the influence of the setting of the positioning notch on the strength of the blowing tube.

[0011] As a further improvement of the utility model, a spray valve is provided on the top of the adapter elbow to facilitate adjustment of the spray intensity.

[0012] As a further improvement of the utility model, the air separation bag is detachably mounted on the outside of the pulse dust collector through a mounting bracket, which is convenient for packaging, transportation, disassembly and maintenance. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0019] like Figure 1-5 The pulse dust removal device installation structure shown includes an air distribution bag 1 and a blowing pipe 2.

[0020] The air distribution bag 1 is detachably mounted on the outside of the pulse dust collector 3 through a mounting bracket 6. The top of the air distribution bag 1 is connected to the air storage bag through an air delivery pipeline 4, and a pulse control valve 5 is provided on the air delivery pipeline.

[0021] A connecting short pipe 7 is distributed on the gas distribution bag 1, and the blowing pipe 2 is connected to the connecting short pipe 7 through a switching elbow 8. A blowing valve 14 is provided on the top of the switching elbow 8 to facilitate the adjustment of the blowing force.

[0022] The two connecting ends of the transfer elbow 8 are provided with plug connectors 9, and the connecting ends of the blowing pipe 2 and the connecting short pipe 7 are provided with plug sockets 10 that cooperate with the plug connectors 9. The plug connector 9 is ringed with ridges, and the plug socket 10 is provided with long slots that cooperate with the ridges.

[0023] The end of the blow pipe 2 is plugged into the pulse dust collector 3. The pulse dust collector 3 is provided with a mounting hole corresponding to the insertion position of the blow pipe 2, and the diameter of the mounting hole is larger than the outer diameter of the blow pipe 2, which reduces the requirements for the processing accuracy of the blow pipe 2 size, the length of the connecting short pipe 7, the plug-in depth of the plug connector 9 and the plug socket 10, and the straightness of the blow pipe 2 on the pulse dust collector 3, thereby reducing the manufacturing cost and the difficulty of installation control. In this embodiment, a drawer-type filter cartridge 15 is tilted in the pulse dust collector 3, and the blow pipe 2 is tilted in the axial direction corresponding to each filter cartridge 15 to achieve the best blowing and cleaning effect.

[0024] A positioning notch 11 is provided on the outer side of the wall of the blow pipe 2 corresponding to the plug-in position and a sealing plate is installed. The sealing plate includes two substrates 12 that are spliced ​​and connected, and a connecting seat 13 is provided on the substrate 12. The connecting seat 13 is provided with a connecting hole and connected by connecting bolts. The thickness of the blow pipe 2 is not less than 8 mm to avoid the influence of the positioning notch on the strength of the blow pipe 2. A sealing gasket 16 is clamped on the splicing surface of the substrate 12 to improve the sealing effect. A support frame 17 is welded and fixed to the outer wall of the pulse dust collector 3 corresponding to the lower edge of the substrate 12 to prevent the end of the blow pipe 2 from vibrating and making noise during the blowing operation or deformation of the end due to lack of support after long-term use. In this embodiment, the outer periphery of the substrate 12 is semicircular and the support frame 17 is in a straight line shape. In the specific implementation, the support frame 17 can also be in an arc shape, or the lower edge of the substrate 12 is in a straight line shape that matches the support frame 17.

[0025] The pulse dust removal device installation structure of this embodiment adopts a detachable connection structure between each component, which is convenient for installation and disassembly maintenance. For example, if a certain adapter elbow 8 needs to be replaced, it is only necessary to remove the sealing plate on the spray pipe 2 connected thereto, and then pull out the spray pipe 2 to release the connection between the spray pipe 2 and the adapter elbow 8 (at this time, the spray pipe 2 is still plugged into the pulse dust collector 3, but the insertion depth is deeper. In order to prevent the spray pipe 2 from sliding into the pulse dust collector 3, the installation gap on the pulse dust collector 3 can also be plugged with a cloth ball or the like). Finally, the adapter elbow 8 to be replaced is pulled out from the connecting short pipe 7 and a new adapter elbow 8 is installed. After the installation is completed, the spray pipe 2 is plugged into the adapter elbow 8 and the plug-in depth of the adapter elbow 8 and the spray pipe 2 is adjusted so that the sealing plate installation position is just located in contact with the outer wall of the pulse dust collector. The whole process is fast and efficient, which greatly improves the maintenance efficiency.
