Description

TECHNICAL FIELD

[0001] The utility model relates to the field of coking furnace, in particular to a coking furnace exhaust port ignition device. BACKGROUND

[0002] The coking furnace is a device for decomposing coal coking, which makes coal decompose into coke and coke oven gas at high temperature by isolating air, and is an important equipment in the coking process. The modern coke oven refers to a horizontal chamber coke oven which can recover coking chemical products and is mainly used for producing metallurgical coke, and is composed of a furnace body and auxiliary equipment. The furnace body of the coke oven is composed of a furnace top, a combustion chamber and a carbonization chamber, a sloping channel area and a heat storage chamber.

[0003] The coke oven gas is a by-product of coking products, which has the characteristics of high heat value and fast combustion. Due to the frequent periodicity of the coke oven gas, the usage of the gas user will fluctuate to some extent, so the coke oven gas needs to be diffused and ignited. The coke oven diffusion ignition system can ignite and burn the raw coke oven gas in time when the coke oven is diffused, effectively preventing environmental accidents caused by direct discharge of raw coke oven gas. The coke oven gas diffusion ignition measure effectively solves the influence of the large motion amplitude of the raw coke oven gas diffusion pipe flap on the pressure fluctuation of the gas collecting pipe, thereby effectively ensuring the stable regulation of the coke oven pressure system and reducing the smoke and fire phenomenon of the coke oven. Not only improves the coke oven gas output rate and prolongs the service life of the coke oven, but also improves the operating environment of the coke oven.

[0004] The existing ignition method for the exhaust port of the coking furnace is mostly through the PLC system according to the pressure signal of the gas collecting pipe, through a series of actions of the ignition system and the execution system, and then through the ignition rod to ignite the raw coke oven gas. The ignition rod is fixed with the position of the exhaust port during installation, which is not convenient to adjust the position, and the ignition rod is mostly fixed on the exhaust port of the coking furnace. With the increase of the service life of the coking furnace and the increase of the ignition diffusion times, it is not convenient to replace the aging ignition rod 4. TECHNICAL CONTENT

Specific implementation

[0021] The technical scheme in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor belong to the protection scope of the utility model.

[0022] Embodiment: refer to Figures 1-4 The utility model discloses a coking furnace exhaust port ignition device, including the positioning inner tube 1 and a plurality of ignition rods 4 that can be installed on the coking furnace exhaust port, the positioning inner tube 1 is equipped with a plurality of link plates 2 that are equidistantly arranged along the circumferential track, a plurality of link plates 2 are connected through the support outer tube 3 that is coaxially distributed with the positioning inner tube 1, the support outer tube 3 is embedded with a plurality of positioning sleeves 31 that are equidistantly arranged along the circumferential track, and a plurality of ignition rods 4 are respectively arranged on the inner side of a plurality of positioning sleeves 31.

[0023] Still include a plurality of groups of detachable clamp sleeve 5, and each group of clamp sleeve 5 can be moved into and out of the positioning sleeve 31, in the process of installing the ignition rod 4, the ignition rod 4 can be located in the adjusting position in the positioning sleeve 31, has the advantage that the flexible adjustment, when the position of the ignition rod 4 is determined, before needing to carry out the ignition and dispersion operation to the gas of the coking furnace exhaust port, the clamp sleeve 5 is in the closed state and falls into the inner side of the positioning sleeve 31. The clamp sleeve with 5 can keep the stable state of the ignition rod 4, and keep the stability in the ignition and dispersion operation process.

[0024] Further, with the increase of the service life of the coking furnace and the increase of the number of ignition dispersion, it can be necessary to replace the aging ignition rod 4. In the process of replacing the ignition rod 4, the movable jacket 5 reduces the time required for disassembling and replacing the ignition rod 4, facilitating the workers to climb to the exhaust port of the coking furnace to perform the replacement operation.

[0025] As shown in Figure 4 , Figure 5 , one end of the jacket 5 is provided with a lug 51, and the lug 51 is provided with a clamping channel 52. The positioning sleeve 31 is provided with a pair of limiting grooves 311 capable of accommodating the lug 51. When the pair of jackets 5 are combined and moved into the inside of the positioning sleeve 31, the lug 51 falls into the inside of the limiting groove 311, so that the jacket 5 in the closed state is in a symmetrical state, avoiding the offset phenomenon of the jacket.

[0026] As shown in Figure 4 , 5 , the positioning sleeve 31 is provided with a guide ring 32 coaxially distributed thereon. The front side of the guide ring 32 is provided with a pair of movable intercepting blocks 6. The guide ring 32 is provided with an arc-shaped guide rail 33. The intercepting block 6 is opposite to one end of the arc-shaped guide rail 33 and is threadedly connected with a guide rod 7. The guide rod 7 is located inside the arc-shaped guide rail 33. When the jacket 5 is placed into the inside of the positioning sleeve 31 and the lug 51 is placed into the inside of the limiting groove 311, the guide rod 7 falls into the inside of the clamping channel 52 under the action of gravity, and the intercepting block 6 is located in front of the lug 51. The arrangement of the intercepting block 6 and the guide rod 7 has a limiting effect on the lug 51 and the jacket 5, which can avoid the lug 51 and the jacket 5 from being separated from the positioning sleeve 31 and falling off. The stability of the jacket 5 in the connected state with the ignition rod 4 and the positioning sleeve 31 is maintained.

[0027] At the same time, the arrangement of the arc-shaped guide rail 33 can make the intercepting block 6 and the guide rod 7 not easy to produce the offset phenomenon in the state of non-human force, further guaranteeing the limiting effect on the lug 51 and the jacket 5.

[0028] As shown in Figure 5 , the guide rod 7 extends through the arc-shaped guide rail 33 to the rear of the intercepting block 6, and one end of the guide rod 7 located behind the intercepting block 6 protrudes outward to form an anti-skid joint 8. The arrangement of the anti-skid joint 8 can avoid the guide rod 7 from being separated from the arc-shaped guide rail 33, and maintain the stability of the guide rod 7 and the intercepting block 6.

[0029] As shown in Figure 2As shown, in order to further maintain the stability of the ignition rod 4 during use, the ignition rod 4 is provided with the remaining fulcrum, a plurality of supporting strips 21 are arranged on the adapter plate 2 and equidistantly distributed along the circumferential track of the positioning inner tube 1, the ignition rod 4 extends through the supporting strips 21 and the positioning inner tube 1 to the inside of the positioning inner tube 1. During the installation and adjustment process, the relative position of the ignition rod 4 and the supporting strips 21 and the positioning inner tube 1 changes with the movement of the ignition rod 4 in the positioning sleeve 31.

[0030] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and not for limiting the present application, although the foregoing embodiments of the present application have been described in detail, for those skilled in the art, it still can be modified, or part of the technical features of the equivalent replacement, any modification, equivalent replacement, improvement, etc., which is within the spirit and principles of the present application, should be included in the scope of protection of the present application.
