PURPOSE: A ventury for a dust collector is provided to improve the efficiency of dedusting by forming a flow forming part on the inner circumference of the ventury. CONSTITUTION: A dust collector includes one or more bag filters and a spraying pipe. The bag filters collect dust from air which is introduced into a housing. The spraying part is spaced apart from the bag filters, and sprays compressed air. A ventury is combined to the upper side of the bag filters to guide the compressed air. A flow forming part is installed on the inner circumference of the ventury, and spirally moves the flow of the compressed air. The flow forming part is a spiral shaped groove(122a), and vibrates the bag filters by changing the flow of the compressed air. |
