Description

Technical Field

[0001] The utility model relates to the technical field of boilers, in particular to a device for clearing and plugging a slag pipe of a solid waste boiler. Background Art

[0002] In industrial production, a large amount of waste gas and waste slag will be generated. In most industrial enterprises, waste gas has been treated with certain specific devices. Because the waste slag is in solid state, some steps in the treatment process are still handled manually. Boiler combustion will produce a large amount of flue gas, which will enter the ash hopper after passing through the dust removal device. A large amount of slag will accumulate in the ash hopper. In addition, during the combustion of the boiler, the combustion will produce a large amount of slag. These slags need to be cleaned regularly. If they are not cleaned in time, the use of the boiler will be affected.

[0003] During the use of the boiler, after a long period of use, slag is very easy to adhere to the inner wall of the boiler. If the slag on the inner wall is not cleaned in time, it will affect the use of the boiler. Secondly, if hard scale is cemented to the inner wall of the boiler, it will also greatly increase the risk of the boiler bursting or even exploding due to thermal expansion and contraction and uneven force. The existing pipeline cleaning device has a simple structure and cannot crush and guide the slag, so that the slag is easily accumulated in the pipeline, affecting the slag cleaning efficiency and the service life of the pipeline.
