Disclosed is a dust-collecting barrow according to the invention. The dust-collecting barrow has a layer of silicon oil on the bottom thereof. The silicon oil is stable; that is, it is difficult for it to react with chemical compounds. The dust-collecting barrow has a plurality of alternately-arranged dividers. When chemical materials and/or particles are sucked into the dust-collecting barrow, heavier materials are first deposited in the silicon oil while lighter materials continuously move forward, and then are deposited in the silicon oil. Furthermore, the dust-collecting barrow is divided by the alternatively-arranged dividers into a plurality of open spaces which are used to absorb various chemical materials or particles, thereby preventing the various chemical materials or particles from reacting with each other.
