Description

Technical Field

[0001] The embodiments disclosed herein relate to the field of coke oven technology, and more specifically, to an automatic ignition device for a coke oven venting system with continuous operation. Background Technology

[0002] Coke oven gas venting is a pressure balancing method. To ensure safe venting and reduce environmental pollution, the automatic coke oven gas venting and ignition device adopts a pressure-adjustable water-sealed automatic venting structure. It can automatically achieve unattended venting and ignition, and automatically adjust the venting rate. This not only meets safety requirements but also saves energy, is practical and reliable, has a long service life, ensures complete combustion, and guarantees environmental compliance. The complete set of equipment consists of a burner, water seal tank, auxiliary tank, ignition device, ignition gas system, steam system, and control system.

[0003] The existing ignition device detects the gas in the coke oven through the detection equipment. When the blower stops running due to a malfunction, the raw gas passes through the water seal trough into the vent pipe, and then is ignited by the high-energy ignition device controlled by the ignition system to burn the raw gas. However, the electrodes in the igniter are easily blocked by tar during use, making it difficult for the electrodes to ignite normally.

[0004] The aforementioned ignition device is prone to tar blockage of the electrodes during use, making it difficult for the electrodes to ignite properly and thus reducing the device's effectiveness. Utility Model Content

[0005] To overcome the above-mentioned defects, the embodiments of this disclosure provide an automatic ignition device for continuous flaring of coke oven flames, which solves the technical problem in the prior art where the electrodes in the igniter are easily blocked by tar during use, making it difficult for the electrodes to ignite normally.

[0006] According to one aspect, at least one embodiment of the present disclosure provides an automatic ignition device for a coke oven venting continuous lamp rotation, which includes a venting pipe, and further includes a connecting pipe, a blocking plate, a plug-in block, a heat insulation block, a conduit, an ignition electrode, a sealing block, a tightening rod, and a sealing cover. The connecting pipe passes through the vent pipe, and a blocking plate passes through the inside of the connecting pipe. A plug-in block is installed on the side of the blocking plate. The heat insulation block passes through the connecting pipe, and the plug-in block is slidably connected to the heat insulation block. A wire tube passes through the inside of the blocking plate, the connecting pipe, and the heat insulation block. An ignition electrode is provided at the inner end of the four sets of wire tubes. The sealing block is threaded through the connecting pipe, and the wire tube passes through the sealing block. The tightening rod is installed on the side of the sealing block. The sealing cover is sleeved on the outer surface of the connecting pipe, and the outer surface of the wire tube passes through the inside of the sealing cover.

[0007] As a preferred embodiment of the coke oven venting continuous automatic ignition device of this utility model, in order to better fix the sealing cover, a fixing frame is installed on the outer surface of the connecting pipe, and a first fixing column is slidably connected inside the fixing frame.

[0008] As a preferred embodiment of the coke oven venting continuous-light automatic ignition device of this utility model, in order to prevent the first fixed column from loosening during use, a fixing pin is threaded through the lower surface of the fixing frame, and one end of the fixing pin threaded into the fixing frame abuts against the first fixed column.

[0009] As a preferred embodiment of the coke oven venting continuous automatic ignition device of this utility model, in order to facilitate the operator to adjust the position of the first fixed column, a fixing plate is installed on the side of the first fixed column, and a second fixed column is installed on the side of the fixing plate.

[0010] As a preferred embodiment of the coke oven venting continuous automatic ignition device of this utility model, in order to prevent the sealing cover from loosening during use, a contact frame is installed on the side of the second fixing column, and an auxiliary block is installed inside the contact frame. The auxiliary block is slidably connected to the inside of the sealing cover.

[0011] As a preferred embodiment of the coke oven venting continuous-lighting automatic ignition device of this utility model, in order to better fix the connecting pipe, an installation ring is sleeved on the outer surface of the venting pipe, and four sets of insertion holes are opened inside the installation ring.

[0012] As a preferred embodiment of the coke oven venting continuous automatic ignition device of this utility model, in order to prevent misalignment during the installation of the connecting pipe, two sets of positioning plates are installed on the outer surface of the connecting pipe, and the outer side of the positioning plates is slidably connected to the mounting ring.

[0013] As a preferred embodiment of the coke oven venting continuous-lighting automatic ignition device of this utility model, in order to facilitate the operator to place the installation ring, a support ring is installed on the outer surface of the venting pipe, and a support rod is installed on the upper surface of the support ring.

[0014] The beneficial effects of the embodiments disclosed herein are as follows: In this disclosure, by removing the sealing cap and then unscrewing the sealing block clockwise, the conduit can be pulled out from the insulation block to clean the ignition electrode. Compared with the prior art where the electrode is blocked by tar after long-term use, this device can clean the ignition electrode regularly, avoiding the situation where the ignition electrode cannot be used normally when the device needs to be vented.

[0015] In this disclosure, by manipulating the second fixed column to move inward, the contact frame moves inward, causing the auxiliary block to be inserted into the sealing cover. Compared with the prior art where it is directly fixed in the vent pipe, this device can waterproof and dustproof the ignition electrode, reduce the number of times dust adheres to the surface of the ignition electrode, and improve the effectiveness of the device.

[0025] like Figures 1-4 As shown, it illustrates an automatic ignition device for coke oven venting continuous operation in one embodiment of the present disclosure, which includes a venting pipe 1, a connecting pipe 2, a blocking plate 3, a plug-in block 4, a heat insulation block 5, a wire threading pipe 6, an ignition electrode 7, a sealing block 8, a tightening rod 9, and a sealing cover 10. like Figure 4As shown, the connecting pipe 2 is installed inside the vent pipe 1. The bottom end of the vent pipe 1 is connected to the gas collecting pipe of the external coke oven. The vent pipe 1 and the gas collecting pipe are controlled one-way by a water seal valve. A baffle plate 3 is installed inside the connecting pipe 2. The baffle plate 3 can block some of the tar. A plug block 4 is installed on the side of the baffle plate 3. A heat insulation block 5 is installed inside the connecting pipe 2. In order to prevent the device from being damaged by excessive temperature, the plug block 4 is slidably connected inside the heat insulation block 5. A wire conduit 6 runs through the inside of the baffle plate 3, the connecting pipe 2, and the heat insulation block 5. An ignition electrode 7 is installed at the inner end of the four sets of wire conduits 6. The ignition electrode 7 is connected to the wiring terminal of the external ignition equipment through the wire conduit 6. A sealing block 8 is threaded inside the connecting pipe 2. The wire conduit 6 runs through the sealing block 8. A tightening rod 9 is installed on the side of the sealing block 8. A sealing cover 10 is sleeved on the outer surface of the connecting pipe 2. The outer surface of the wire conduit 6 runs through the inside of the sealing cover 10.

[0026] like Figure 3 As shown, a fixing frame 11 is installed on the outer surface of the connecting pipe 2. A first fixing post 12 is slidably connected inside the fixing frame 11. A fixing pin 13 is threaded through the lower surface of the fixing frame 11. One end of the fixing pin 13, which is threaded into the fixing frame 11, abuts against the first fixing post 12. A fixing plate 14 is installed on the side of the first fixing post 12. A second fixing post 15 is installed on the side of the fixing plate 14. A contact frame 16 is installed on the side of the second fixing post 15. An auxiliary block is installed inside the contact frame 16. The auxiliary block is slidably connected inside the sealing cover 10. A square groove is opened inside the sealing cover 10. The size of the square groove is adapted to the size of the auxiliary block.

[0027] like Figure 1 and Figure 2 As shown, an installation ring 17 is fitted onto the outer surface of the vent pipe 1. The installation ring 17 has four sets of insertion holes 18 inside. Two sets of positioning plates 19 are installed on the outer surface of the connecting pipe 2. The outer side of the positioning plates 19 is slidably connected to the installation ring 17. A support ring 25 is installed on the outer surface of the vent pipe 1. A support rod 26 is installed on the upper surface of the support ring 25. The support rod 26 can pass through the insertion hole 18 when the operator replaces or cleans the ignition electrode 7, so that the support ring 25 supports the installation ring 17.

[0028] In this embodiment, as Figure 1 and Figure 2As shown, a positioning block 20 is slidably connected inside the mounting ring 17. A positioning pin 21 is threaded through the inside of the positioning block 20. One end of the positioning pin 21, which is threaded through the positioning block 20, is threaded inside the mounting ring 17. A positioning plate 22 is installed on the inner side of the positioning block 20. The positioning plate 22 is slidably connected inside the mounting ring 17. A semi-circular groove is opened on the upper surface of the positioning plate 22. The size of the semi-circular groove is adapted to the radius of the connecting pipe 2. A buffer spring 23 is installed inside the positioning plate 22. A buffer rod 24 is installed at the top of the buffer spring 23. The buffer rod 24 passes through the positioning plate 22. The outer surface of the buffer rod 24 passes through the positioning piece 19. One end of the buffer rod 24, which passes through the positioning piece 19, presses against the mounting ring 17. It should be noted that the outer surface of the vent pipe 1 is spirally welded with a ladder that allows operators to move upwards. The application scenario of the ignition electrode 7 is to prevent the raw coal gas from being transported normally when the external gas blower suddenly fails and trips, causing the pressure of the coke oven gas collecting pipe to rise sharply and a large amount of raw coal gas to escape from the coke oven riser pipe, furnace door, furnace frame, etc. Therefore, the device is equipped with four sets of connecting pipes 2, insulation blocks 5, wiring pipes 6, and ignition electrodes 7, so that the ignition electrodes 7 can be evenly distributed inside the vent pipe 1. The ignition command is preset by the external PLC control cabinet. Normally, the two are kept lit in turn, which indirectly reduces the number of times tar adheres and blocks the ignition electrodes 7. During venting, all four ignition devices work, ensuring the efficiency of the device's venting.

[0029] In this embodiment, when cleaning is required, the operator moves along the escalator to the position of the mounting ring 17, loosens the positioning pin 21 counterclockwise, manipulates the positioning plate 22 to slide out along the inside of the mounting ring 17, and the positioning block 20 slides out along the mounting ring 17, so that the connecting pipe 2 is disengaged from the semi-circular groove. The positioning plate 22 moves downward, causing the buffer spring 23 to move downward. The buffer spring 23 moves downward, causing the buffer rod 24 to move downward. The buffer spring 23 gradually extends, and the buffer rod 24 moves downward and is pulled out from the positioning piece 19. Manipulate the connecting tube 2 to be pulled out along the inside of the vent tube 1, so that the positioning piece 19 slides out from the mounting ring 17. The mounting ring 17 moves downward along the vent tube 1 due to gravity. The mounting ring 17 moves downward and contacts the support ring 25, so that the support rod 26 passes through the insertion hole 18. Loosen the fixing pin 13 counterclockwise, manipulate the first fixing post 12 to move outward along the fixing frame 11, the first fixing post 12 moves outward and drives the fixing plate 14 to move outward, the fixing plate 14 moves outward and drives the second fixing post 15 to move outward, the second fixing post 15 moves outward and drives the contact frame 16 to move outward, the contact frame 16 moves outward and drives the auxiliary block to move outward, the auxiliary block moves outward and is pulled out from the sealing cover 10; Remove the sealing cap 10 from the outer end of the connecting tube 2, loosen the sealing block 8 counterclockwise, so that the clamping rod 9 gradually disengages from the heat insulation block 5 during the rotation of the sealing block 8, manipulate the heat insulation block 5 to slide out along the connecting tube 2, so that the plug block 4 slides out along the inside of the heat insulation block 5, pull out the wire tube 6 from the inside of the heat insulation block 5, clean or replace the outer surface of the ignition electrode 7 to prevent the device from being difficult to ignite during the release process. After the operator has finished cleaning or replacing the ignition electrode 7, reversing the above steps will allow the ignition electrode 7 to return to its original position. It should be noted that by regularly inspecting and cleaning or replacing the ignition electrode 7, the amount of tar adhering to the device after long-term use is reduced, and the cleaning difficulty for operators is reduced, so as to avoid affecting the normal ignition of the device.

[0030] It should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure and are not intended to limit it. Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
