Deposit removing device of coke oven gas conveying pipeline

The utility model discloses a deposit removing device of a coke oven gas conveying pipeline, and belongs to the technical field of a pipeline deposit removing method and device. According to the technical scheme, a hole is formed in the coke oven gas conveying pipeline and is connected with an ammonium hydroxide pipeline; hot ammonium hydroxide is sprayed into the coke oven gas conveying pipeline through the ammonium hydroxide pipeline to dissolve the deposit in the coke oven gas conveying pipeline; the dissolved condensed liquid is discharged from the coke oven gas conveying pipeline. The deposit removing device is composed of an ammonium hydroxide tank, an ammonium hydroxide pipeline, an ammonium hydroxide pump and water draining devices, the ammonium hydroxide tank is connected to spraying holes of the coke oven gas conveying pipeline through the ammonium hydroxide pipeline, and the lower portion of the coke oven gas conveying pipeline is connected with the water draining devices. The deposit removing device overcomes the defect of a traditional method that the deposit is removed by dismounting a pipeline, the occurrence that the coke oven gas stops being conveyed due to the dismounting of the pipeline is avoided, the production can be carried out smoothly, and the environmental pollution cannot be caused. The deposit removing device is easy to operate and good in effect, and has obvious economic benefits and social benefits.
