Description

Technical Field

[0001] The utility model relates to the technical field of coking waste gas treatment, in particular to a coking tower top tower organic gas collection device. Background Art

[0002] Coking is a refining process mainly used for residual oil and coal. Coking uses heavy oil, residual oil, and even asphalt as raw materials. After heating, they enter the coking tower and undergo cracking and condensation reactions at specified temperature and pressure, ultimately generating products such as gas, gasoline, wax oil, and coke. The commonly used method for decoking needle coke is mainly hydraulic decoking and open-air stacking of raw coke. That is, when decoking the needle coke coking tower, the top and bottom covers of the coking tower are opened, and the coke cutter enters from the top cover. The cut needle coke raw coke and cutting water enter the open-air coke pool from the bottom cover. The raw coke in the coke pool is dehydrated by standing still in the open air, then loaded by a bridge crane and sent to downstream equipment by a belt conveyor. Since there is no gas collection device during decoking in the coking tower, the random diffusion of organic gas will cause environmental pollution.

[0003] The Chinese patent provides an automatic gas collection hood on the top of the coke tower, with the publication number CN218521191U, which includes a base adapted to the smoke exhaust port, a rotatable top cover at one end of the base, an outer ring of the base provided with an enclosure extending upward and fixed thereon, an air suction hood provided on the upper part of the enclosure to shield the smoke exhaust port, a fixed air suction port provided on the air suction hood, and a fixed plate provided between the fixed plates for sliding internally.

[0004] The above-mentioned device uses the air intake to collect water vapor, and the collected smoke and dust can be processed later. An automatic gas collection hood is added to collect the gas at the top cover machine, which can realize automatic collection and transportation of open top cover gas, and collect and process unorganized emission gas when the top cover of the coke tower is opened. However, the air intake is used to absorb water vapor containing impurities. After long-term use, the pipeline is easily blocked, affecting subsequent suction, and the water vapor is directly extracted, and subsequent processing is more cumbersome. Utility Model Content

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] Example 1

[0026] Combine Figures 1-4 A coking tower top tower organic gas collection device includes a gas collection component 2 arranged above a smoke outlet 1. The gas collection component 2 has an air suction hood 3 and a leak-proof cover 5. The air suction hood 3 is fixedly installed at the upper position of the outer circle of the smoke outlet 1. An electric telescopic rod 4 is installed at the front end of the air suction hood 3. The leak-proof cover 5 is fixedly installed at the end of the push rod of the electric telescopic rod 4.

[0027] See Figure 2 , it is further obtained that the bottom surface of the leak-proof cover 5 is in contact with the top surface of the smoke outlet 1, and an intake pipe 6 is provided on both sides of the air intake hood 3. A plurality of intake ports 7 that adaptably match the intake pipe 6 are opened on both sides of the air intake hood 3, and the intake pipe 6 is connected to the intake port 7 through an air inlet pipe. A plurality of blowing ports 9 are installed at the upper position of the interior of the air intake hood 3 through a shaped hose. One end of the blowing ports 9 extending out of the air intake hood 3 is connected to each other through an air supply pipe 8, and one end of the air supply pipe 8 is connected to a connecting pipe 10.

[0028] Specifically, by controlling the retraction of the push rod of the electric telescopic rod 4, the leak-proof cover 5 can be driven away from the top of the smoke outlet 1 to remove the obstruction of the smoke outlet 1. Thereafter, the decoking device can be extended from the smoke outlet 1 to perform decoking according to the existing technology. At the same time, the organic gas floating at the smoke outlet 1 will be sucked into the suction pipe 6 through the suction port 7 to prevent it from diffusing at will. During the absorption, the connecting pipe 10 can be connected to the external auxiliary air pipe in advance so that the external gas can be transported to the blowing port 9 for spraying. Through continuous air jetting, the organic gas can be suppressed to prevent it from floating upward.

[0029] Example 2

[0030] See Figure 2 、 Figure 3 and Figure 4, and on the basis of Example 1, it is further obtained that a water absorption box 17 is installed at the top of the suction pipe 6, a high molecular water-absorbing resin is arranged inside the water absorption box 17, a rotating rod 11 is arranged inside the suction pipe 6, the front end of the rotating rod 11 is rotatably connected to the suction hood 3, and a transmission wheel group is arranged at the front end of the rotating rod 11, a cleaning motor 13 is installed on both sides of the front end of the suction hood 3, the driving shaft of the cleaning motor 13 is connected to the rotating rod 11 through the transmission wheel group, the transmission wheel group consists of a driving wheel, a transmission belt, and a driven wheel, and the driven wheel is connected to the rotating rod 11, and the front end of the driven wheel is installed with the cleaning motor 13 through a connecting block, a linkage mother rod 14 is movably installed inside the rotating rod 11, and the front end of the linkage mother rod 14 is connected to the end of the push rod of the electric telescopic rod 2 12, A number of vents are provided at the connection between the air pipe 6 and the water suction box 17. A hot air delivery pipe 18 is connected to the outer ring of the air suction pipe 6 at one side. The linkage mother rod 14 is hinged with a linkage sub-rod 15, and the linkage sub-rod 15 is movably connected to a cleaning scraper 16 at one end away from the linkage mother rod 14. The air suction pipe 6 is hollow cylindrical, and the cleaning scraper 16 is adaptively matched with the end of the linkage sub-rod 15 away from the inner wall of the air suction pipe 6. The water suction box 17 is a transparent frame. The top of the water suction box 17 is detachably mounted with a top cover by fixing bolts, and a handle is provided at the rear position of the top of the top cover. The interior of the rotating rod 11 is provided with a movable groove adaptively matched with the linkage mother rod 14. When the linkage sub-rod 15 is in the expanded state, the cleaning scraper 16 is in contact with the inner wall of the air suction pipe 6 on the side away from the linkage sub-rod 15.

[0031] Specifically, during the decoking process, the high molecular water-absorbing resin arranged inside the water absorption box 17 can absorb a small amount of water vapor entering the intake pipe 6, so as to improve the dryness inside the intake pipe 6 and prevent impurities from sticking due to excessive moisture. At the same time, the cleaning motor 13 and the electric telescopic rod 2 12 can be started, and the push rod of the electric telescopic rod 2 12 drives the linkage mother rod 14 and the linkage child rod 15 to move, so as to expand the cleaning scraper 16 inside the intake pipe 6. After expansion, the cleaning motor 13 cooperates with the transmission wheel group to drive the cleaning scraper 16 to rotate in contact with the inside of the intake pipe 6, thereby cleaning the inner wall of the intake pipe 6.

[0032] During actual operation, when personnel use the decoking equipment to decoke, they can control the push rod of the electric telescopic rod 4 to retract, which can drive the leak-proof cover 5 away from the top of the smoke outlet 1 to remove the obstruction of the smoke outlet 1. After that, the decoking device can be extended from the smoke outlet 1 to decoke according to the existing technology. At the same time, the organic gas floating at the smoke outlet 1 will be sucked into the suction pipe 6 through the suction port 7 to prevent it from diffusing at will. During absorption, the connecting pipe 10 can be pre-connected with the external auxiliary air pipe so that the external gas can be transported to the blowing port 9 for spraying. Through continuous air jetting, the organic gas can be suppressed to prevent it from floating upward, which is convenient for alleviating the production environmental protection pressure and facilitating the subsequent emission standards after washing with alkali solution in the washing tower.

[0033] After moisture enters the intake pipe 6, the high molecular water-absorbing resin arranged inside the water absorption box 17 can absorb the small amount of water vapor entering the intake pipe 6, so as to improve the dryness inside the intake pipe 6 and prevent impurities from sticking due to excessive moisture. At the same time, the cleaning motor 13 and the electric telescopic rod 2 12 can be started, and the push rod of the electric telescopic rod 2 12 drives the linkage mother rod 14 and the linkage child rod 15 to move, so as to expand the cleaning scraper 16 inside the intake pipe 6. After expansion, the cleaning motor 13 cooperates with the transmission wheel group to drive the cleaning scraper 16 to rotate inside the intake pipe 6, thereby cleaning the inner wall of the intake pipe 6, preventing impurities from adhering to the air inlet part of the intake pipe 6 after long-term use, and preventing a significant impact on the subsequent gas entry.
