[0002] The coke oven riser is an important component of the coke oven. Its main function is to discharge the raw gas generated during the coking process. During the coking process, the coal is heated and decomposed in the carbonization chamber to produce raw gas. The raw gas enters the gas collection pipe and other subsequent gas purification systems through the riser.

[0003] At present, the commonly used methods for igniting raw gas in coke oven straight pipes on the market are manual ignition with an electronic igniter or installation of an automatic ignition device around the water seal groove of the large cover of each straight pipe, and ignition within 2-5 seconds of the moment the large cover of the straight pipe is opened. The former is a purely manual operation with low cost, but the risk factor is extremely high, while the latter is relatively safe but the investment cost is relatively high. Generally, 70 sets of igniters for 70 holes of coke oven cost about 1 million yuan; therefore, there is an urgent need for an automatic ignition device for raw gas in the coke oven riser to solve the above-mentioned defects.

[0020] See also Figure 1-4The utility model provides an automatic ignition device for raw gas in a coke oven riser, comprising a high-voltage electric spark gun 1, an ignition tube 2 being fixedly mounted on the end of the high-voltage electric spark gun 1, and a base 3 being fixedly mounted on the bottom of the high-voltage electric spark gun 1, while a connecting foot is welded to the bottom of the base 3, and the base 3 is screwed and fixed to the surface of a connecting platform 6 through the connecting feet on both sides of the bottom, guide seats 61 are welded on both sides of the bottom of the connecting platform 6, and the guide seats 61 are mounted on the surface of a guide rail 62, while a workbench 63 is welded and fixed to the bottom of the guide rail 62.

[0021] Working principle: When in use, the high-voltage electric spark gun 1 is installed on the connecting platform 6 through the base 3 at the bottom. At this time, the external switch of the electro-hydraulic push rod 65 is started, and the piston rod end of the electro-hydraulic push rod 65 is screwed and fixed to the rectangular fixing plate welded on the right side of the connecting platform 6. The electro-hydraulic push rod 65 can drive the high-voltage electric spark gun 1 to move laterally on the surface of the workbench 63, and the ignition distance of the ignition tube 2 can be adjusted. The bottom of the ignition tube 2 is supported and fixed to the surface of the connecting platform 6 by the stabilizing seat 4 and the support rod 5 to ensure the stability of the ignition tube 2 during ignition and prevent it from tilting. At the same time, when the connecting platform 6 is driven to move laterally, the guide seats 61 on both sides of its bottom are respectively slidably set on the surfaces of the two groups of guide rails 62, which can limit and guide the laterally moving connecting platform 6 to ensure the stability of the connecting platform 6 and the high-voltage electric spark gun 1 during laterally moving.

[0022] A stabilizing seat 4 is installed at the bottom of the right end of the ignition tube 2, and the stabilizing seat 4 is arc-shaped and screwed to the bottom of the ignition tube 2. At the same time, a support rod 5 is screwed to the bottom of the stabilizing seat 4, and the bottom of the support rod 5 is screwed to the surface of the connecting platform 6.

[0023] As a preferred embodiment, the base 3 is a "U"-shaped structure made of metal material, and the high-voltage electric spark gun 1 is fixed on the surface of the connecting platform 6 through the base 3.

[0024] An electro-hydraulic push rod 65 is installed on the right side of the connecting platform 6 , and the piston rod end of the electro-hydraulic push rod 65 is screwed and fixed to a rectangular fixing plate welded on the right side of the connecting platform 6 .

[0025] As a preferred embodiment, the connecting platform 6 is a transverse motion structure on the surface of the workbench 63, and the guide seat 61 is adapted to the size of the guide rail 62. At the same time, the two groups of guide seats 61 are respectively slidably arranged on the outside of the two groups of guide rails 62.

[0026] A guide groove is provided inside the guide seat 61 , and the cross-sections of the guide groove and the guide rail 62 are both T-shaped. At the same time, the connecting platform 6 covers the surface of the workbench 63 and is limited and guided by two sets of guide seats 61 and guide rails 62 .

[0027] As a preferred embodiment, the workbench 63 is in a rectangular shape as a whole, and support bases 64 are installed on both sides of the workbench 63. The cross-section of the support bases 64 is in an I-shape.

[0028] This renovation only requires the installation of a set of high-voltage electric spark guns. The high-voltage electric spark gun 1 is installed on the top coal-loading car near the side of the straight pipe cover. When the coal-loading car is aligned with the coal-loading hole, the high-voltage electric spark gun 1 is extended by the electro-hydraulic push rod 65. The gun head sprays high-voltage electric sparks at the moment the cover is opened, igniting the raw coal gas and realizing automatic ignition of the straight pipe, which not only ensures safety but also greatly reduces costs.

[0029] The coal loading furnace number is N, the coke pushing is N+2, and the ignition is N+4. When the coal loading car is aligned with the coal loading hole No. N, the electro-hydraulic push rod drives the high-voltage electric spark gun 1 to automatically extend and align with the edge of the N+4 straight pipe and wait, and sends this signal to the OPR system. After receiving the signal, the OPR immediately controls the straight pipe cover to open, and returns the opening action signal to the coal loading car. The coal loading car immediately starts the electro-hydraulic push rod and exciter, so that the high-voltage electric spark gun 1 ignites while moving forward. After the high-voltage electric spark gun 1 reaches the center of the straight pipe, it continues to ignite for 5 seconds, and then automatically returns to the starting position, fully ensuring the ignition of the raw coal gas.

[0030] The millimeter-level distance measurement of the magnetostrictive displacement sensor can achieve precise alignment of 70 straight pipes, solving the problem of gun head collision that may occur when the straight pipes are not in a straight line during installation. At the same time, an interlock is added between the push rod position and the coal car tracking system. The car cannot move when the push rod is not in the starting position, which increases safety. After testing, the entire ignition process can ignite the gas within 5 seconds, and the time from the ignition of the high-voltage electric fire gun 1 to the ignition of the gas is generally about 2 seconds, which fully meets the requirements of the coke oven and can realize unmanned and fully automatic operation of the riser.
