The utility model provides a buggy dust collector. This buggy dust collector includes: sack cleaner, sack cleaner include buggy entry and gas outlet, cyclone, cyclone include gas access and clean air out, draught fan, draught fan are provided with the purified gas discharge port, wherein, the gas outlet is linked together with the gas access, and clean air out is linked together with the draught fan. Through introduce cyclone between sack cleaner and draught fan, will follow in the sack cleaner exhaust gaseous phase and carry steam and get into and cool off the desorption among the cyclone for though the micro - buggy steam that the gaseous phase was carried condenses for the liquid drop turns into sewage desorption from the gas, thereby solved and have micro - buggy and lead to air pollution's problem in the draught fan combustion gas from the sack cleaner. And the desorption of steam in cyclone has still been solved the draught fan and has been gone out the easy problem of blockking up of inlet pipe.
