Description

Technical Field

[0001] The utility model relates to a dust removal system, and more particularly to a dust removal system suitable for a locomotive machinery workshop. Background Art

[0002] Existing dust removal systems, such as patent publication number CN 212418935 U, disclose a locomotive machinery room dust removal device comprising a housing within which a dust removal fan and a filter chamber are arranged side by side. The dust removal fan's air outlet is a silencer outlet, and the dust removal fan's air inlet duct is connected to the filter chamber. The filter chamber houses a filter cartridge, a dust collection box is located at the bottom of the filter cartridge, and a dust collection system is located at the top of the filter cartridge. The dust collection unit of the dust collection system has four dust collection hoods arranged vertically and spaced apart. The dust collection unit is located outside the housing and is connected to the dust collection system via bellows. Several pulse purge valves automatically controlled by a microcomputer are arranged at inclined intervals from top to bottom within the housing behind the filter cartridge. The pulse purge valves blow air toward the filter cartridge to vibrate and clean dust adhering to the filter cartridge. This utility model adopts a synchronous blowing, suction, and filtering structure, performing blowing, dust removal, and filtering simultaneously, effectively improving the cleaning requirements of the machinery room and enhancing work efficiency.
