DeveloPMeNt of A fIBeR fIlteR foR DuSt ChAMBeRSPurpose. Development of a new design of the dust chamber for dedusting the air of aspiration systems equipped with a modu lar fiber filter.Methodology. In the development, a complex method was used, which provided for the critical analysis and synthesis of litera ture, security documents for inventions and utility models regarding the types and designs of dust chambers for purification of aspiration air from industrial dust, as well as a theoretical rationale for electrostatic dust collection in a fiber filter that is based on the laws of physics and aerodynamics.findings. Research studies on various types and designs of dust chambers have shown the feasibility of developing a new design of the dust chamber equipped with a modular fiber filter to increase its efficiency. Such a design of the dust chamber for the puri fication of aspiration air will improve the state of sanitary and hygienic working conditions of workers of mining and processing plants and mines.originality. Ways of increasing the efficiency of dust collection of industrial dust by dust chambers due to the placement of different dust precipitation elements are considered. A new dust chamber design has been developed for dedusting air of aspiration systems. The chamber is equipped with a modular fiber filter that operates in interchangeable dust deposition and regeneration modes depending on dust load.Practical value. To improve the efficiency of dust collection in aspiration systems on the basis of theoretical justification and experimental tests, a new design the dust chamber has been developed equipped with a modular fiber filter that operates in inter changeable dust deposition and regeneration modes, which ensures effective dedusting of air from ventilation emissions.
