Description

Technical Field

[0001] This utility model relates to the field of tail coke recovery technology, specifically to a water-flushing tail coke recovery device. Background Technology

[0002] During the coking process, after the coke pusher pushes the coke into the coke oven, the coke that falls off at the oven door during the door removal process is called tail coke. The tail coke treatment and recovery device is an important component of the coke pusher or coke quencher.

[0003] Currently, widely used tail coke recovery devices in the industry generally adopt a combined treatment mode of introducing tail coke into a storage hopper and cooling with quenching water. That is, the tail coke is introduced into a sealed storage hopper pre-stored with quenching water via a conveying structure, and the tail coke is cooled by direct contact with the water, while simultaneously being collected and recovered. However, this traditional mode has revealed significant drawbacks in practical applications: Firstly, to ensure the cooling effect of the tail coke, a large amount of quenching water needs to be continuously injected, resulting in high water consumption per unit time, increasing the company's water resource costs and burdening subsequent wastewater treatment. Secondly, the cooled tail coke and quenching water form a mixed slurry. Existing devices lack an efficient solid-liquid separation structure, making it impossible to achieve immediate separation of tail coke and water. This not only requires additional equipment for secondary treatment but may also affect the subsequent storage and reuse of tail coke due to residual moisture, ultimately leading to low tail coke recovery efficiency and serious resource waste.

[0004] In conclusion, there is an urgent need for a water-flushing tail coke recovery device to solve the above problems. Utility Model Content

The return water pipe 202 is welded to the drain pipe 201. The filter hole 203 is formed on the return water pipe 202. The filter screen 204 is fixed in the filter hole 203 by screws. During use, one end of the drain pipe 201 is connected to the water storage mechanism to inject coke flushing water into the coke storage hopper 100. Then, the tail coke is injected into the coke storage hopper 100 and cooled by the coke flushing water. After treatment, the filter hole 203 and the filter screen 204 are combined to filter the tail coke, realizing the separation of coke flushing water and tail coke. The filtered coke flushing water is injected into the water storage mechanism for storage under the action of the return water pipe 202 and the drain pipe 201.

[0031] like Figure 1 , Figure 3 as well as Figure 4As shown, in this embodiment, the connection between the sealing cover plate 303 and the discharge port of the coke storage hopper 100 is sealed and waterproofed.

The support 304 provides an installation position for the hydraulic rod 301, realizing the connection between the hydraulic rod 301 and the sealing cover plate 303 and the bearing plate 302. The fixed part of the hydraulic rod 301 is hinged to the support 304 located on the bearing plate 302, and the movable part of the hydraulic rod 301 is hinged to the support 304 located on the sealing cover plate 303. After the coke flushing water is drained, the hydraulic rod 301 is controlled to work so that it drives the sealing cover plate 303 to rotate and open the discharge port of the coke storage hopper 100. At this time, the tail coke separated from the water is discharged through the discharge port for recycling.

[0032] like Figure 1 , Figure 3 as well as Figure 5 As shown, in this embodiment, a water flushing assembly 400 is also provided on the upper end of one side wall of the coke storage hopper 100. The water flushing assembly 400 includes a water injection pipe 401 fixed on the side wall of the coke removal hopper, and a centrifugal pump 402 is installed on the water injection pipe 401. An air extraction assembly 500 is installed on the back wall of the coke storage hopper 100. The air extraction assembly 500 includes an air suction hood 501 with a figure-eight structure fixed on the back wall of the coke storage hopper 100. A filter plate 502 is installed in the suction port of the air suction hood 501. A blower 503 is connected to one end of the air suction hood 501. An exhaust pipe 504 is installed on the exhaust port of the blower 503. The exhaust pipe 504 has an L-shaped structure. A filter is installed near the bottom of the exhaust pipe 504. The purification component 600 includes a purification box 601 fixed on the exhaust pipe 504. An activated carbon adsorption net 602 is slidably installed inside the purification box 601. During use, coking water is injected into the coke storage hopper 100 through the water injection pipe 401. The centrifugal pump 402 can realize the quantitative injection of coking water, thereby saving water resources. The steam generated by coking is extracted through the suction hood 501 by the exhaust fan 503. The filter plate 502 can filter impurities, and the extracted steam is discharged through the exhaust pipe 504. During the steam discharge process, the activated carbon adsorption net 602 in the purification box 601 can purify the steam, thereby avoiding pollution to the atmosphere.

[0033] The specific implementation process of this embodiment is as follows: First, the device is placed in position and connected to an external power source. During use, the flushing water is injected into the coke storage hopper 100 through the water injection pipe 401. The centrifugal pump 402 can achieve quantitative injection of the flushing water, thereby saving water resources. Then, the tail coke is injected into the coke storage hopper 100 containing the flushing water. At this time, the flushing water cools the tail coke. The steam generated during flushing is extracted through the suction hood 501 by the exhaust fan 503. The filter plate 502 can filter impurities, and the extracted steam is discharged through the exhaust pipe 504. During the steam discharge process, the activated carbon adsorption net 602 in the purification box 601 can purify the steam, thereby avoiding pollution to the atmosphere. The tail coke is injected into the coke storage hopper 100 containing coke flushing water. At this time, the coke flushing water cools and extinguishes the flame of the tail coke. After the tail coke is extinguished and cooled, the drain pipe 201 is opened by the solenoid valve 205. At this time, the coke flushing water flows out through the filter screen 204 in the filter hole 203, while the tail coke is blocked by the filter screen 204, thus separating the coke flushing water from the tail coke. After the coke flushing water is drained, the hydraulic rod 301 is operated to drive the sealing cover plate 303 to rotate and open the discharge port of the coke storage hopper 100. At this time, the tail coke separated from the water is discharged through the discharge port for recycling. On the one hand, the coke flushing water is recycled and reused, saving water resources, and on the other hand, it is convenient to recycle the tail coke, effectively improving the recycling effect of the device on the tail coke.
