ASPIRATION DUST COLLECTOR Russian patent published in 2023 - IPC B08B15/02 B04C9/00 

FIELD: air cleaning technologies.

SUBSTANCE: invention can be used to clean dust emissions. Aspiration dust collecting plant contains a local suction of dust from process equipment, connected by a flexible air duct to a vortex inertial dust collector located in a housing mounted on a trolley with wheels on counter swirling flows, made of a cylindrical working and conical parts, which is connected through a sluice gate to a dust-accumulating hopper and is equipped with an exhaust fan, power supply and air duct system with dust air flow rate regulators. The local dust suction is installed under the cover of the shelter along the axis of the process equipment and is made of metal or synthetic material in the form of a pipeline with inlets over its entire surface, the total area of which is not less than the cross-sectional area of the local dust suction pipeline. The flexible air duct is made of reinforced flexible material with a smooth inner surface. The dust storage hopper is equipped with a valve for unloading the deposited dust.

EFFECT: increased operational reliability of the dust collecting plant and, accordingly, increased its productivity.
