Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] The utility model provides: a wet electrostatic precipitator which is easy to clean, such as Figure 1-Figure 5 As shown, it includes a protective frame 1 and a dust collector body 13 installed inside the protective frame 1, a plurality of positioning boxes 5 are symmetrically installed on both sides of the protective frame 1, and a group of bellows 6 is bolted and installed inside each group of positioning boxes 5; a top plate 7 is bolted and installed on the top of the protective frame 1, and two groups of winding rollers 11 are symmetrically installed on the upper part of the top plate 7, and a pulling rope 12 is wound inside each group of winding rollers 11; side grooves 14 are opened on both sides of the dust collector body 13, and a movable baffle 18 is slidably installed inside each group of side grooves 14, and a plurality of air exchange baffles 24 are installed through each group of side grooves 14, and a plurality of filter screens 20 are installed through each group of movable baffles 18, and the pulling rope 12 is fixedly connected to the movable baffle 18.

[0026] Preferably, several groups of air outlet plates 2 are symmetrically mounted on both sides of the protective frame 1, and each group of air outlet plates 2 is symmetrically provided with two groups of slots 3 located on the outside of the air outlet, and two groups of elastic limit plates 4 are fixedly installed inside each group of slots 3. The air outlet plates 2 are bolted to the output side of the positioning box 5, and the slots 3 opened on the output side of the air outlet plates 2 limit the elastic limit plates 4. The slots 3 can be engaged with the elastic protrusions 21 after the movable baffle 18 moves, so that the elastic protrusions 21 are inserted into the two groups of elastic limit plates 4 to limit the use height of the movable baffle 18, thereby ensuring that the filter 20 can correspond to the air exchange baffle 24 to enable the bellows 6 installed inside the positioning box 5 to stably supply air to the inside of the dust collector body 13, thereby ensuring the air conversion efficiency inside the dust collector body 13 and ensuring the drying speed inside the dust collector body 13.

[0027] Furthermore, there are two groups of limit windows 8 symmetrically running through the left and right sides of the top plate 7, and two groups of rolling limit wheels 9 are rotatably installed inside each group of limit windows 8.
