Description

Technical Field

[0001] The utility model relates to the technical field of smoke filtering equipment, in particular to a smoke filtering mechanism which is easy to self-clean. Background Art

[0002] The high-titanium slag electric furnace is an important equipment for the production of sponge titanium. It is mainly used to produce high-titanium slag rich in titanium dioxide. This electric furnace uses anthracite or metallurgical coke as a reducing agent. After mixing with titanium concentrate and preparing pellets, it is placed in the electric furnace for high-temperature reduction smelting. The high-titanium slag electric furnace usually produces flue gas during the production and preparation process. Flue gas pollution is one of the important issues facing the current environmental protection field. In order to reduce flue gas pollution and achieve environmental protection effects, a flue gas filtration mechanism is usually used to filter the flue gas.

[0003] The smoke filter mechanism on the market generally uses a filter mesh with a spray component to process the smoke. During the process, more impurities will accumulate on the bottom surface of the filter mesh. At this time, the traditional smoke filter mechanism lacks a component that can self-clean the impurities on the filter mesh, and cannot process the impurities on the filter mesh, which will cause more impurities to block the filter mesh, affecting the subsequent filtering effect and causing inconvenience to the user. In view of this, we proposed a smoke filter mechanism that is easy to self-clean. Utility Model Content
