Abstract
Description
Technical Field
[0001] This utility model relates to the field of coal coking technology, and in particular to a dry quenching and coking system for reducing dust emissions. Background Technology
[0002] In recent years, environmental protection requirements from all levels of government have become increasingly stringent. Steel plants have always been key targets for environmental remediation, and coking plants are among the most challenging areas. Many companies are required to meet the ultra-low emission Class A standard. To maintain their Class A status, it is necessary to further improve the control of fugitive emissions after dry quenching coke loading. Currently, the dry quenching coke loading system consists of coke tanks and loading devices.
[0003] Currently, in actual production, there is a significant problem of dust overflow during the coke charging process: after the coke is loaded, the empty coke can leaves the charging device, which breaks the sealed environment above the charging device, greatly increasing the entry of wind and resulting in poor dust removal effect; during the movement of the charging device, before the dry quenching furnace cover is closed, the dust emanating from the dry quenching furnace opening escapes from the top of the charging device, causing fugitive emissions. Utility Model Content
[0004] The purpose of this invention is to address the above-mentioned situation by providing a dry quenching coke loading system that reduces dust emissions. This dry quenching coke loading system is an improvement on the existing technology and effectively solves the problem of dust dispersion during the movement of the loading device.

Two running tracks are arranged side by side on both sides of the top port of the charging device, and a mobile trolley is mounted on the two running tracks.

[0008] Furthermore, the furnace cover opening and closing mechanism described in this utility model includes a robotic arm and a furnace cover. The furnace cover is mounted on the robotic arm and, driven by the robotic arm, performs the opening and closing operation of the dry quenching furnace opening.
[0009] Furthermore, the mobile coke pot described in this utility model is equipped with a mobile lifting rod on its top, which is connected to a mobile trolley, and the track of the mobile trolley is set directly above the dry quenching furnace.
[0010] Furthermore, the shape of the cover plate in this invention is consistent with the shape of the upper port of the insertion device.

[0020] See Figures 1-5 This utility model relates to a dry quenching coke charging system for reducing dust emissions. It includes a furnace cover opening and closing mechanism located on one side of the dry quenching furnace opening, a charging device for dry quenching coke, a tail coke hopper 9 located on one side of the dry quenching furnace opening, and a movable coke canister 3 suspended above the dry quenching furnace opening. Furthermore, the charging device in this utility model includes a feeding hopper 5, which is round at the top and bottom. A material container is located inside the feeding hopper, and a track and a drive mechanism are located outside the feeding hopper. The drive mechanism moves the feeding hopper along the corresponding track. Two running tracks 10 are arranged side by side on both sides of the top port of the loading device. A movable trolley 12 is mounted on the two running tracks, and a moving motor 11 is mounted on the movable trolley. The bottom of the movable trolley is equipped with wheels. A cover plate 4 is provided at the front of the movable trolley to cover the upper port of the loading device. The cover plate moves laterally left and right along the running tracks under the movement of the movable trolley. The upper layer of the cover plate is a metal plate, and the lower layer is a high-temperature resistant heat-insulating material layer. Limit switches are provided at both ends of the running tracks. Furthermore, in this invention, the bottom of the cover plate has a perimeter-level anti-escape skirt 13 made of soft, high-temperature resistant material, and the diameter of the anti-escape skirt is consistent with the outer edge of the upper port diameter of the loading device. Furthermore, in this invention, the shape of the cover plate is consistent with the shape of the upper port of the loading device.
[0021] Furthermore, in this embodiment, the furnace cover opening and closing mechanism includes a robotic arm 7 and a furnace cover 6. The furnace cover is mounted on the robotic arm and, driven by the robotic arm, performs the opening and closing operation of the furnace opening of the dry quenching furnace 8. Furthermore, in this invention, the top of the movable coke tank is provided with a movable lifting rod 2, which is connected to a movable trolley. The track of the movable trolley is located directly above the dry quenching furnace.
[0022] In this utility model, conventional mobile coke tanks, coke loading devices, dry quenching furnaces, tail coke hoppers, etc. are all existing technologies. Their structures and working principles are basically based on existing technologies. However, the core of this application is to set up a mechanism on the loading device to prevent leakage.
[0023] In practice, a sealing cover plate (approximately 100mm thick) is first prepared, with a metal upper layer and a high-temperature resistant insulation material lower layer. Two running tracks are installed and welded to both sides of the upper port of the loading device, with a length designed to extend from the standby position of the loading device to the coke loading position. A mobile motor is installed on one side of the cover plate and moves synchronously with the cover plate on the running tracks.
[0024] After the above work is completed, two limit switches are installed at each end of the running track to ensure accurate forward and backward positioning.
[0025] Add a control module to the existing control system of the loading device, and interlock the control module into the PLC control program of the loading device.
[0026] like Figure 1 The image shows the state when the loading device is above the tail coke hopper. At this time, the furnace cover is closed, and there is a cover plate on the loading device to protect the tail coke hopper from rain and prevent rainwater from entering and clogging it. Figure 2 The image shows the state of the coke loading operation. At this time, the cover plate is moved open, the loading device is moved to the top of the dry quenching furnace opening, and the coke can is moved over for coke loading operation. Figure 3 When the coke loading operation is completed and the coke can is ready to leave, the cover plate moves into position to seal the upper port of the loading device. In addition, the anti-escape skirt can effectively prevent dust in the dry quenching furnace from escaping through the upper port of the loading device.
[0027] The three state diagrams above correspond to different time periods of operation. The movement of the cover plate and the movement of the loading device are linked by an added control module.
[0028] The present invention has the following beneficial effects: (1) It achieves the sealing of the loading device after coke loading is completed, preventing wild wind from entering and affecting the dust removal effect, and also preventing dust from scattering. (2) In the standby state, the cover plate of the present invention is placed on the upper part of the loading device, which can play a role in preventing rain in rainy weather, preventing rainwater from entering the tail coke hopper below the loading device and causing the tail coke discharge pipe of the tail coke hopper to be blocked.
