Description

Technical Field

[0001] This utility model relates to the field of coke oven gas purification technology, and in particular to a novel coke oven gas purification device. Background Technology

[0002] Coke oven gas, also known as coke oven coal gas, is a byproduct of the coking industry. It is a combustible gas produced in a coke oven after the coking coal is prepared by blending several types of bituminous coal and undergoing high-temperature dry distillation to produce coke and tar products.

[0003] Coke oven gas is a byproduct of the coking process and contains various impurities such as tar, naphthalene, hydrogen sulfide, and ammonia. If these impurities are not effectively removed, they can cause corrosion and blockage in subsequent gas utilization equipment, reducing the equipment's lifespan and operating efficiency, and also polluting the environment. In existing technologies, most purification devices purify hydrogen sulfide in coke oven gas by spraying desulfurization liquid. However, the nozzles are fixed and have a limited spraying area, resulting in insufficient contact between the desulfurization liquid and the coke oven gas, reducing the purification effect and making it impractical. Therefore, a new type of coke oven gas purification device needs to be designed to address these issues. Utility Model Content

The elastic mechanism includes a spring 9 installed on the outer wall of the connecting rod 7. The two ends of the spring 9 are elastically connected to the upper surface of the cleaning box 2 and the bottom wall of the pressing block 8, respectively.

[0022] A first motor 11 is fixedly installed on the upper end face of the impurity removal box 2 via a support plate 10. An eccentric wheel 12 is fixedly installed on the outer wall of the output shaft of the first motor 11. An extrusion groove that mates with the eccentric wheel 12 is opened on the upper end face of the extrusion block 8. A cleaning opening that communicates with the interior is opened on the outer wall of the impurity removal box 2. A sealing plate 13 that mates with the cleaning opening is fixedly installed on the outer wall of the impurity removal box 2 via multiple bolts. A connecting pipe 14 that communicates with the interior is fixedly installed on the upper end face of the impurity removal box 2. A purification tank 16 that communicates with the interior is fixedly installed on the upper end face of the storage tank 3 via a fixing mechanism. The fixing mechanism includes multiple fixing plates 15 that are fixedly installed on the upper end face of the storage tank 3. The end of each fixing plate 15 is fixedly connected to the outer wall of the purification tank 16.

[0023] The end of the connecting pipe 14 is connected to the interior of the purification tank 16. A rotating pipe 17 is rotatably installed on the upper surface of the purification tank 16. A spray pipe 18 is fixedly installed on the outer wall of the rotating pipe 17. Multiple nozzles 19 connected to the interior are fixedly installed on the outer wall of the spray pipe 18. A second motor 21 is fixedly installed on the upper surface of the purification tank 16 through a mounting plate 20. Gears 22 are fixedly installed on both the output shaft of the second motor 21 and the outer wall of the rotating pipe 17. The two gears 22 mesh with each other. A circulation pump 23 and an addition pump 24 are fixedly installed on the upper surface of the base 1. The inlet pipes of the circulation pump 23 and the addition pump 24 extend into the interior of the storage tank 3. A circulation pipe 25 is fixedly installed on the outer wall of the outlet pipe of the circulation pump 23. The outer wall of the circulation pipe 25 is connected to the rotating pipe 17 through a connecting mechanism.

[0024] In use, the pump 24 adds desulfurization liquid to the storage tank 3. Coke oven gas enters the impurity removal box 2 through the inlet pipe 4. Inside the impurity removal box 2, the filter plate 5 and filter cloth 6 work together to intercept and filter impurities and dust in the coke oven gas. Simultaneously, the first motor 11 drives the eccentric wheel 12 to rotate. The eccentric wheel 12 then contacts the inner wall of the extrusion groove, causing the extrusion block 8 to be subjected to force, which, through the connecting rod 7, moves the filter plate 5 and filter cloth 6 downwards. As the extrusion block 8 moves... During the process, the spring 9 can also be squeezed. When the eccentric wheel 12 is not in contact with the inner wall of the extrusion groove, the spring 9 can restore its deformation and cause the connecting rod 7 to drive the filter plate 5 and filter cloth 6 to move up and reset. When the eccentric wheel 12 continues to rotate and intermittently contacts the inner wall of the extrusion groove, the filter plate 5 and filter cloth 6 can be shaken up and down with the cooperation of the spring 9, so as to shake off the impurities and dust on the bottom wall of the filter cloth 6 to ensure the flow of coke oven gas. The coke oven gas after impurity removal can be flowed into the purification tank 16 through the cooperation of the connecting pipe 14.

[0025] Meanwhile, the circulating pump 23 can pump the desulfurization liquid inside the storage tank 3 and discharge it into the spray pipe 18 through the cooperation of the circulating pipe 25, the connecting sleeve 26, and the rotating pipe 17. The desulfurization liquid is then sprayed out from the spray pipe 18 through multiple nozzles 19, thereby removing hydrogen sulfide from the coke oven gas and purifying it. During the purification process, the second motor 21 can drive the rotating pipe 17 to rotate inside the connecting sleeve 26 through two gears 22, thereby allowing the rotating pipe 17 to pass through the spray pipe. 18 drives multiple nozzles 19 to rotate, thereby rotating and spraying the desulfurization liquid, increasing the spraying area of ​​the desulfurization liquid, improving the purification effect on coke oven gas, and the sprayed desulfurization liquid can be pumped back by the circulation pump 23 and discharged for spraying, thus realizing the recycling of the desulfurization liquid. The purified coke oven gas can be discharged from the inside of the purification tank 16 through the exhaust pipe 27. When it is necessary to clean the impurities and dust inside the impurity removal box 2, multiple bolts can be loosened to release the fixing of the sealing plate 13, and then the cleaning opening can be opened to clean the inside of the impurity removal box 2.
