Description

Technical Field

[0001] The utility model relates to the technical field of coke ovens, in particular to a coke oven airing smoke treatment device. Background Art

[0002] When the coke oven is in use, that is, in the coke production process, the riser cover needs to be opened to dry the oven at the end of coking. The schematic diagram of the partial structure of the smoke escape at the drying oven of the existing coke oven is as follows: Figure 1 As shown, it mainly includes a coke oven 1, a riser cover 2 and a cylinder 3. The cylinder 3 is fixed on the coke oven 1 and the riser cover 2. During the drying process, the cylinder 3 drives the riser cover 2 to move upward on the coke oven 1. Tar and residual raw coal gas exist on the upward riser cover 2, which leads to the emission of yellow smoke and blue smoke during the drying process, and there is an environmental pollution problem. In order to avoid this problem, at present, the emission of yellow smoke and blue smoke is reduced by artificial ignition during the drying process. Although this method can reduce the emission of yellow smoke and blue smoke during the drying process, it requires manual operation and leads to high labor intensity. In addition, it is difficult to ignite the first time when igniting manually, and there will still be disorderly emission of raw coal gas, which cannot meet the requirements of the "Opinions on Promoting the Implementation of Ultra-low Emissions in the Coking Industry (Draft for Comments)", that is, it cannot meet the requirements of environmental protection.

DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0019] Example 1

[0020] Reference Figure 2 , 3 5. A drying furnace flue gas treatment device comprises a fixed pipe 5, which is fixed on the coke oven 1. A feed pipe 6 runs through and is fixed on the fixed pipe 5. An ignition gun 4 is connected and fixed on the feed pipe 6. The ignition gun 4 is provided with combustion fuel through the feed pipe 6. A reinforcement rod 8 is fixed to the ignition gun 4 and the fixed pipe 5. The setting of the reinforcement rod 8 fixes the inclination angle of the ignition gun 4, so that when the ignition gun 4 is ignited, the yellow smoke and blue smoke generated when the riser cover 2 is moved up can be ignited. The ignition gun 4 is electrically connected with an automatic starting mechanism, which is fixed on the coke oven 1 and the push rod of the cylinder 3. When the riser cover 2 is moved up, the ignition gun 4 can be started, so that the ignition gun 4 can immediately ignite the yellow smoke and blue smoke generated when the riser cover 2 is moved up, so as to prevent the yellow smoke and blue smoke from escaping and polluting the surrounding environment.

[0021] During use, when the riser cover 2 moves up, the automatic starting mechanism will control the ignition gun 4 to ignite, and the scattered yellow smoke and blue smoke generated when the riser cover 2 moves up will be ignited in time, which increases the timeliness of the ignition of the yellow smoke and blue smoke, reduces the phenomenon of disorderly emission of waste gas, meets environmental protection requirements, and in addition, reduces the labor intensity of personnel.

[0022] Example 2

[0023] Based on Example 1, Figure 2-6As another preferred embodiment of the utility model, the difference from embodiment 1 is that the automatic starting mechanism includes a fixing frame 9 and a fixing block 12, a plug-in plate 10 is fixed on the fixing frame 9, a top plate 11 is fixed on the plug-in plate 10, a hole 13 is penetrated on the fixing block 12, the plug-in plate 10 penetrates the hole 13, the top end of the top plate 11 is inserted in the hole 13, a touch switch 14 is fixed in the hole 13, the touch switch 14 and the ignition gun 4 are electrically connected with a wire 7, and the touch switch 14 is used to control the opening and closing of the ignition gun 4.

[0024] Telescopic limit mechanisms are fixed on the fixed blocks 12 in the holes 13 on both sides of the touch switch 14, and a first fixed plate 17 is fixed on the two telescopic limit mechanisms. The first fixed plate 17 is in contact with the touch switch 14, and multiple rows of rollers 18 are fixed on the first fixed plate 17. The bottom row of rollers 18 is in contact with the inclined surface of the top plate 11. The top of the top plate 11 is set with an inclined surface. The top of the top plate 11 with an inclined surface will not be stuck by the bottom row of rollers 18 during the upward movement of the top plate 11, thereby ensuring the smooth upward movement of the top plate 11.

[0025] The telescopic limiting mechanism includes a cylinder 15 and an insertion rod 16, which are respectively fixed on the fixed block 12 in the hole 13 and the first fixed plate 17. The insertion rod 16 is inserted in the cylinder 15. The cooperation between the cylinder 15 and the insertion rod 16 prevents the first fixed plate 17 from tilting during movement, thereby ensuring the effect and safety of the first fixed plate 17 squeezing the touch switch 14.

[0026] When in use, when the riser cover 2 moves up, the top plate 11 will immediately contact the rollers 18 in the bottom row. Under the pressure of the top plate 11, the multiple rollers 18 press the touch switch 14 through the first fixed plate 17. When the touch switch 14 is pressed, the touch switch 14 will control the ignition gun 4 to ignite, thereby allowing the ignition gun 4 to promptly ignite the yellow smoke and blue smoke generated when the riser cover 2 moves up.

[0027] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
