Description

Technical Field

[0001] The utility model relates to the technical field of industrial silicon smelting, in particular to industrial silicon fume dust removal equipment. Background Art

[0002] Industrial silicon smelting produces flue gas, which contains a variety of harmful substances, such as dust, sulfur dioxide and nitrogen oxides. The composition and volume of these flue gases are affected by many factors, such as the particle size of the raw materials, the feeding method and the operating conditions. The characteristics of the flue gas include that the main component of the flue dust is SiO2, which is called microsilica powder. This dust has fine particles, low density, high specific resistance, strong cohesion, strong adhesion, and is not easy to settle, which can seriously pollute the environment.

[0003] Chinese utility model patent CN219355732U discloses an industrial silicon fume dust removal device, which relates to the technical field of industrial silicon smelting production.
