Description

Technical Field

[0001] The utility model relates to the technical field of coke oven gas purification, in particular to a coke oven gas purification device. Background Art

[0002] Coke oven gas, also known as coke oven gas, is a high-calorific value gas due to its high combustible content. It is a combustible gas produced by the high-temperature dry distillation of coking coal in a coke oven, producing coke and tar. It is a byproduct of the coking industry.

[0003] A search revealed a coke oven gas purification device disclosed in a Chinese patent document [Application Number: CN202323330315.6]. This coke oven gas purification device includes a scraper mechanism connected to an open shell to prevent clogging at the bottom of the purification mechanism. The scraper mechanism includes a mounting frame fixedly connected to the open shell, a motorized telescopic rod fixedly connected to the mounting frame, a connecting rod fixedly connected to the telescopic end of the motorized telescopic rod, an end of the connecting rod remote from the motorized telescopic rod extending into the open shell, and a scraper fixedly connected to the end of the connecting rod remote from the motorized telescopic rod, which contacts the bottom end of the purification mechanism.

[0004] When the device disclosed in this patent is in use, it can clean organic matter by the action of the scraper. After cleaning, the organic matter falls directly to the bottom of the inner cavity of the open shell. The air inlet of the device is located at the bottom of the inner cavity of the open shell.

[0023] In order to further illustrate the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the following is a detailed description of the specific implementation method, structure, characteristics and effects of the present invention in combination with the accompanying drawings and preferred embodiments.

[0024] See also Figure 1-5As shown, a coke oven gas purification device includes a purification box 1, and an air inlet pipe 2 is connected to the bottom of one side of the purification box 1. With the cooperation of the air inlet pipe 2, the flue gas to be purified can be discharged into the interior of the purification box 1, so as to facilitate subsequent purification. The inner cavity of the purification box 1 is fixedly connected to a filter shell 3. The inner cavity of the filter shell 3 is used to store activated carbon for filtering the flue gas, so that the flue gas inside the purification box 1 is purified under the action of the activated carbon. An electric telescopic rod 4 is bolted to one side of the purification box 1. The output shaft of the electric telescopic rod 4 passes through the interior of the purification box 1 and is fixedly connected to a scraper plate 5. The top of the scraper plate 5 is movably connected to the bottom of the filter shell 3. Under this action, the The scraper plate 5 is used to clean the bottom of the filter housing 3 by means of the electric telescopic rod 4, so as to clean the organic matter adhering to the bottom of the filter housing 3, thereby preventing the organic matter from clogging the filter housing 3 and affecting the device's purification of the flue gas. The surface of the scraper plate 5 is equipped with a receiving mechanism 6, which can receive the organic matter cleaned by the scraper plate 5, thereby preventing the organic matter from falling directly into the inside of the purification box 1, making it convenient for the subsequent cleaning of the organic matter. A collection box 7 is fixedly connected to one side of the inner cavity of the purification box 1, and a drain valve 8 is installed on one side of the purification box 1. The bottom of the collection box 7 is designed as an inclined structure. The drain valve 8 is used in conjunction with the collection box 7. Under the cooperation of the receiving mechanism 6, the collected organic matter can be uniformly discharged into the interior of the collection box 7, and under the action of the drain valve 8, the organic matter can be easily discharged from the interior of the device, and the cooperation of the collection box 7 and the drain valve 8 makes it more convenient for the staff to clean up the organic matter. The inner cavity of the filter shell 3 is fixedly connected with a mounting frame 9, and a stirring mechanism 10 is installed on the surface of the mounting frame 9. A connecting rope 11 is provided on one side of the stirring mechanism 10, and the other end of the connecting rope 11 is fixedly connected to a connecting frame 12. One side of the connecting frame 12 is fixedly connected to the surface of the scraper plate 5, and under this action, the scraper plate 5 can be connected to the connecting frame 12 through the connecting frame 12 when it moves. The cooperation of the connecting rope 11 drives the stirring mechanism 10 to rotate, thereby stirring the activated carbon inside the filter shell 3, which not only facilitates the discharge of smoke, but also makes the activated carbon particles uniform, thereby improving the purification effect of the device on smoke. The inner cavity and surface of the filter shell 3 are both installed with guide wheels 13, and the surface of the guide wheel 13 is movably connected to the surface of the connecting rope 11. Under this action, the connecting rope 11 can be guided, so that the friction between the connecting rope 11 and the filter shell 3 is reduced when it is pulled, which effectively improves the service life of the connecting rope 11, and can also guide the connecting rope 11, so that the position of the connecting rope 11 is more accurate.

[0025] The receiving mechanism 6 includes a receiving plate 61, both sides of which are rotatably connected to the surface of the scraping plate 5, and both sides of the surface of the receiving plate 61 are fixedly connected to a torsion spring 62, and the other end of the torsion spring 62 is fixedly connected to the surface of the scraping plate 5. Under this action, the receiving plate 61 can be rotated and returned to its original position under the action of the torsion spring 62. Moreover, the receiving plate 61 can be limited under the action of the position of the scraping plate 5 to prevent the receiving plate 61 from being excessively tilted and affecting the subsequent discharge of organic matter. Two points on one side of the receiving plate 61 are fixedly connected to a connecting rod 63, one end of the connecting rod 63 It is fixedly connected with a moving wheel 64, and the connecting rod 63 is of inclined structural design. The surface of the moving wheel 64 is movably connected to the inner wall of the purification box 1. Under this action, after the scraper plate 5 cleans the filter shell 3, the organic matter falls on the top of the receiving plate 61. After the moving wheel 64 contacts the inner wall of the purification box 1, the receiving plate 61 is rotated under the action of the inclination of the connecting rod 63, so that the organic matter on the top is poured into the interior of the collection box 7. When the electric telescopic rod 4 drives the scraper plate 5 to return to its original position, the receiving plate 61 can be returned to its original position under the action of the torsion spring 62, so as to facilitate the subsequent use of the receiving plate 61.

[0026] The stirring mechanism 10 includes a stirring frame 101 that rotates on the bottom of the mounting frame 9. The top of the stirring frame 101 penetrates the top of the mounting frame 9 and is rotatably connected to the inner wall of the penetration point. The top of the stirring frame 101 is fixedly connected to a take-up drum 102, which is fixedly connected to one end of the connecting rope 11. The take-up drum 102 is movably connected to the surface of the connecting rope 11. The bottom of the mounting frame 9 is fixedly connected to a clockwork spring 103, and the other end of the clockwork spring 103 is fixedly connected to the surface of the stirring frame 101. Under this action, when the connecting rope 11 moves, the take-up drum 102 can be pulled to rotate, thereby causing the stirring frame 101 to rotate and stir the activated carbon particles inside the filter shell 3. When the connecting rope 11 returns to its original position, the stirring frame 101 can be rotated in the opposite direction under the action of the clockwork spring 103, so that the take-up drum 102 can wind the connecting rope 11.

[0027] It is worth noting that the technical features such as the purification box 1 and the filter shell 3 proposed in this technical solution should be regarded as the technology in the comparative case. The specific structure, working principle, and possible control method and spatial layout method of these technical features can be selected according to the conventional selection in this field, and this technical solution will not be further elaborated.

[0028] Working principle: First, activated carbon particles are put into the interior of the filter shell 3, and then the flue gas is discharged into the interior of the purification box 1 through the air inlet pipe 2, so that the flue gas is purified under the action of the filter shell 3 and the activated carbon particles. When it is necessary to clean the bottom of the filter shell 3, the staff turns on the electric telescopic rod 4 to make the scraper plate 5 clean the bottom of the filter shell 3, and the cleaned organic matter will fall on the top of the receiving plate 61. When the moving wheel 64 contacts the inner wall of the purification box 1, the receiving plate 61 can be rotated under the action of the shape of the connecting rod 63, thereby pouring the organic matter into the interior of the collection box 7, so that the staff can use the sewage valve 8 to clean the organic matter. While the scraper plate 5 moves, the connecting rope 11 is pulled to move through the cooperation of the connecting frame 12. When the connecting rope 11 moves, the take-up reel 102 drives the stirring frame 101 to rotate, thereby disturbing the activated carbon particles inside the filter shell 3, and when the scraper plate 5 returns to its original position, the connecting rope 11 is conveniently wound with the cooperation of the spring 103.
