The pulse bag-type dust collector is a common dust collector used in feed production and processing, the existing pulse bag-type dust collector comprises a dust hopper, a dust collection box body and an upper box body, a filter bag is arranged in the dust collection box body, dust-containing gas enters the dust hopper from an air inlet duct during operation, coarse dust particles directly fall into the bottom of the dust hopper, fine dust particles upwards enter the dust collection box body along with the turning of air flow, dust is deposited on the outer surface of the filter bag, and the filtered gas enters the upper box body to a clean gas collecting pipe exhaust duct and is exhausted to the atmosphere through an exhaust fan. When in ash removal, the pulse valve is opened to carry out pulse blowing ash removal by compressed air. Because the existing pulse dust collector collects dust from the side edge and wind power flows upwards in the dust collection box body, a dust collection cloth bag is easily not full of dust and needs to be stopped for dust removal; in addition, during the ash cleaning process, the wind direction of the pulse airflow is downward, and dust easily overflows from the dust suction port.
