Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

The embodiment of the utility model discloses a dust and waste gas treatment device, which is shown in fig. 1, and comprises an absorption tank 1, wherein a water outlet 11 and an air inlet 12 are formed in the bottom of the absorption tank 1, a water inlet 13 is formed in the side wall of the absorption tank 1, an air outlet 14 is formed in the top of the absorption tank 1, water is filled in the absorption tank 1, meanwhile, a plurality of layers of screens 2 are arranged in the absorption tank 1 at intervals along the axial length direction of the absorption tank 1, the screens 2 are all positioned below the water inlet 13, and when the water level in the absorption tank 1 meets the requirement, the screens 2 are all positioned below the liquid level. When the dust waste gas is introduced into the absorption tank 1 through the air inlet 12, the water in the absorption tank 1 absorbs dust particles in the dust waste gas, and meanwhile, the screen 2 can enable the dust waste gas to be changed into a plurality of small bubbles when passing through the screen 2, so that the dust waste gas is in full contact with the water, and the dust particles in the dust waste gas can be dispersed into the water more fully. Meanwhile, in this embodiment, the number of the screens 2 is preferably three, and the three-layer screens 2 can scatter dust and exhaust gas multiple times, so as to improve the filtering cleanliness of the dust and exhaust gas. Meanwhile, the mesh number of the screen 2 is in the range of 10-30 meshes, in the embodiment, the mesh number of the screen 2 is preferably 15 meshes, and the screen 2 in the mesh number range can better pass dust waste gas and can make bubbles formed by the dust waste gas smaller.
