Description

Technical Field

[0001] The utility model relates to the technical field of waste gas recovery equipment for dry coke quenching, and in particular to a waste gas utilization device for dry coke quenching. Background Art

[0002] Coke dry quenching refers to the process of drying and quenching coke using high-temperature coal gas from a gasifier or other equipment during the coke oven gasification process. In this process, the coke is usually in a high-temperature state. By exposing it to coal gas, moisture and volatiles are removed, thereby improving the combustion performance and quality of the coke. Coke dry quenching usually includes several steps such as a gasifier, drying and quenching. Through coke dry quenching, moisture and volatile substances in the coke can be effectively removed, thereby improving the quality and combustion efficiency of the coke. This process helps to produce high-quality coke, while also recovering energy from coke oven gas and improving energy efficiency. During the coke dry quenching process, some waste gases are generated, including: carbon monoxide and carbon dioxide, nitrogen oxides, volatile organic compounds and particulate matter. The components in these waste gases may cause a certain degree of pollution to the environment, so these waste gases need to be treated and purified during the production process.

[0003] After searching, the Chinese patent with the authorization announcement number CN216778315U discloses a dry coke quenching waste gas purification device, including a purification tank, an air inlet pipe is provided at the top of the purification tank, and a fan is fixed on the upper surface of the purification tank near the air inlet pipe, and an annular tube is fixed on the top of the purification tank. In the utility model, a purification tank, an air inlet pipe, a fan, a water pump, an annular tube, a nozzle and a collecting device are provided, and the collecting device includes a collecting barrel, a filter, an electric heating plate, a drain pipe and a hydraulic rod. When the dry coke quenching waste gas is processed, the collecting device is moved to the bottom of the purification tank, and then the collecting barrel is driven up by the hydraulic rod to dock with the bottom of the purification tank. When the waste gas enters the purification tank, the coke powder in the waste gas will be precipitated by the water mist sprayed by the nozzle, and finally fall into the collection barrel. After being filtered by the filter, the water is discharged from the drain pipe, and the coke powder will stay on the surface of the filter. Finally, the coke powder is dried by the electric heating plate, so that the device can recycle the coke powder in the waste gas.

[0004] However, there are still some shortcomings in the above technology. When the existing dry quenching waste gas utilization device is in use, muddy coke powder is easily attached to the inner wall of the purification tank, which is inconvenient to clean and easily causes waste of resources. Therefore, we propose a waste gas utilization device for dry quenching to solve this problem. Utility Model Content
