This utility model discloses a gas
filtration device, which includes an inlet cabinet and an outlet cabinet. The inlet cabinet is positioned above the outlet cabinet, and a filter screen is installed between the two cabinets. Two dust collection bags are installed on both sides inside the inlet cabinet, and the dust collection bags are surrounded by a partition net. A ventilation cavity is formed between the adjacent partition nets on the outer sides of the two dust collection bags. Through holes are provided on the side panels of the inlet and outlet cabinets, as well as on the
doors of both cabinets. A filter box is located below the filter screen, and a filter
assembly is installed inside the filter box. An exhaust fan is located below the filter box, and the exhaust port on the filter box is connected to the air inlet of the exhaust fan via a ventilation
pipe. The gas
filtration device inputs gas through the side panel of the inlet cabinet, filters it through the dust collection bags and the filter box, and outputs it through the side panel of the outlet cabinet. This effectively filters
fine particulate matter near the ground, maintaining a high level of cleanliness in the space where
machine racks and workbenches are located in the workshop.
