Abstract

Technical Field
[0001] The utility model relates to the technical field of calcium carbide furnace flue treatment, in particular to a calcium carbide furnace pipeline encrustation prevention blowing device. Background Art
[0002] At present, in the normal production process of calcium carbide furnace, the main raw materials are coke and lime. When the raw materials react in the furnace, a large amount of gas will be generated. The gas contains tar and other large amounts of dust particles, which are easy to condense on the pipe wall. In addition, the pipe will bend due to the layout of the entire calcium carbide furnace system. Long-term condensation will cause the inner diameter of the pipe to become smaller, the fan frequency to increase, and the temperature in the purification and filtration chamber to be too high. In severe cases, the clean gas flue will be blocked, and normal production cannot be achieved.
[0003] Usually, the calcium carbide furnace is shut down to clean the inspection manholes on each floor. Shovels and crowbars are used, and multiple operators take turns to clean the manholes. The cleaning time is long and not only labor-intensive, but also the quality is difficult to control due to incomplete cleaning, which causes a lot of inconvenience to the subsequent safe production. It is urgent to overcome the problem of cleaning dust accumulated in the clean gas flue of the calcium carbide furnace. Summary of the invention
[0004] The utility model provides a calcium carbide furnace pipeline anti-crusting blowing device, which overcomes the shortcomings of the above-mentioned prior art and can effectively solve the problem that the dust accumulation in the existing calcium carbide furnace clean gas flue is difficult to clean.
