Wet dust collector

The invention provides a wet dust collector belonging to the technical field of mechanisms and solving the problem of complex structure of the existing dust collector. The wet dust collector comprises a shell internally provided with a cavity, wherein an inlet and an outlet which are communicated with the shell are formed in the shell; the shell is internally provided with a partition plate; the interior of the shell is partitioned by the partition plate to form two cavities, namely a cavity I and a cavity II which are adjacent left and right; the lower part of the cavity I is communicated with the lower part of the cavity II; the inlet is located in the upper part of the cavity I; the outlet is located in the top of the cavity II and is fixedly connected with a filter screen; the inlet of the cavity I is provided with a spraying mechanism capable of spraying water mist; the cavity II is internally provided with a baffling mechanism capable of baffling air flow; and a water outlet communicated with the inner cavity of the shell is also formed in the bottom of the shell. The wet dust collector is simple in structure and convenient to mount and dismount.
