Abstract

PURPOSE: To prolong the life of filter cloths by providing automatic dampers at the inlets of the filter cloths, and uniformly dustributing dust-laden gaseous flow to the respective baglike filter cloths and roughly removing dust, thereby reducing the dust concn. flowing to the filter cloths.
CONSTITUTION: Automatic balancing dampers 30 are provided at the inlets in the bag parts of filter cloths 6, and when dust-laden gaseous flow collides against each damper 30 at a nonuniform flow rate distribution, the rates of opening and closing of the dampers 30 vary with the flow rates of collision. The dampers of higher rates of flow close, and the gaseous flow that cannot flow into the filter cloths flows to the other filter cloths. Since the gaseous flow colliding against the dampers accompanies abrupt deceleration, the coarse particles contained in the dust-laden gaseous flow settle in the bottom of a hopper, and only the gaseous flow of low dust concn. flows to the filter cloths.
