| titleOfInvention | Coke oven air suction pipe adjusting butterfly valve spraying system and control method thereof |
| abstract | The invention provides a coke oven air suction pipe adjusting butterfly valve spraying system and a control method thereof, wherein the spraying system comprises a spraying nozzle before a valve, a spraying nozzle after the valve, a high-pressure ammonia water branch pipeline, a low-pressure steam branch pipeline, a spraying pipeline after the valve and a spraying pipeline before the valve; the front valve spraying nozzle and the rear valve spraying nozzle spray the adjusting butterfly valve from the front side and the rear side; the inlet of the spraying nozzle in front of the valve is connected with the high-pressure ammonia water branch pipeline through a spraying pipeline in front of the valve; the inlet of the spraying nozzle behind the valve is connected with the low-pressure steam branch pipeline through the spraying pipeline behind the valve. The low-pressure steam and the high-pressure ammonia water are provided in the coke oven production to spray the adjusting turning plate on the gas suction pipe, so that the problem of adsorption of substances such as tar, naphthalene, coal powder and the like on the valve plate of the adjusting butterfly valve is thoroughly solved, the response speed of the valve is improved, the adjusting performance of the adjusting butterfly valve is improved, the phenomenon that the valve plate of the adjusting butterfly valve is clamped is avoided, the service life of the adjusting butterfly valve is prolonged, and a solid foundation is laid for stable and safe production of the coke oven. |
