This invention discloses an environmentally friendly, low-emission bag filter dust collector, relating to the technical field of bag filter dust collectors. The dust collection box has several mounting seats evenly embedded at equal intervals at its top. An outer frame tube is threaded onto the outer side of the bottom of each mounting seat, and an inner frame tube is threaded onto the inner side of the bottom of each mounting seat. An outer bag is fitted onto the outer side of the outer frame tube, and an inner bag is embedded into the inner wall of the inner frame tube. Several through slots are formed at equal angles along the circumference at the top of the mounting seat corresponding to the position between the outer and inner frame tubes. This invention can construct a dual-channel dust collection path and a synchronous dust removal path. During dust collection, the dust collection pressure is monitored in real time, enabling automatic switching between the two paths. This indirectly achieves uninterrupted dust collection and continuous dust removal, improving the compatibility and stability between dust collection and dust removal operations, enhancing the dust collection effect, reducing the wear rate of the outer and inner bags during operation, extending their effective service life, and indirectly improving their endurance stability and working efficiency.
