The invention provides a graded capturing plate for painting mist and an efficient dry-type painting mist capturing and filtering device. A plurality of graded capturing plates for painting mist are arranged in each capturing device, and comprise flow equalizing and oil paint intercepting subunits; filtering materials for intercepting small oil paint particles are arranged in cavities; the flow equalizing and oil paint intercepting subunits are connected and supported by a box body made of a hardboard material; each capturing device is taken as an independent box body, and is conveniently and singly replaced. The capturing and filtering device has the advantages that complete air flow equalizing is realized, through the scientific design of the structural forms of all layers, air can pass through intercepting layers and filtering layers uniformly and completely, oil paint particles in air are completely intercepted and captured at all stages, the whole capturing and filtering device forms a three-dimensional painting mist capturing structure, the painting mist capturing and absorbing capability is improved greatly, the consumption of the filtering material is reduced, water pollution is completely eliminated, pollution on air and soil is reduced, the energy consumption is reduced, energy is saved, environment is protected, and the production cost is reduced.

The invention belongs to the field of industrial equipment, and in particular relates to an acid gas self-purifying centrifugal fan for mine work, which includes a main body of the fan, an air inlet pipe is fixedly connected to the air inlet of the main body of the fan, and the side wall of the air inlet pipe runs through Embedded with multiple auxiliary cylinders, the two auxiliary cylinders on the same vertical line are provided with a ring made of the same cotton thread, and the left and right sides of the air inlet pipe are equipped with drive boxes, and the drive boxes are fixedly connected to the outside of the air inlet pipe The multiple cotton threads on the same side all run through the side wall of the drive box and are driven by the drive mechanism in the drive box. The drive mechanism includes a rotating shaft, one end of which is rotatably connected to the outer wall of the air inlet pipe, and is fixedly installed on the side wall of the drive box. The driving part is fixedly connected with the other end of the rotating shaft, the driving box is filled with alkaline solution, the side wall of the driving box is fixedly connected with a fixing plate, the fixing plate is provided with a tapered hole, and the cotton thread runs through the corresponding tapered hole. hole. The invention can efficiently and completely remove the acid gas in the air.
