DETAILED DESCRIPTION

[0028] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the specific implementation methods, structures, features and effects of the present invention are described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0029] See also Figure 1-Figure 7 As shown, the present invention provides a high-humidity multi-scale dust purification device, including a sedimentation chamber 1 installed on the first floor, the exhaust hole at the top of the sedimentation chamber 1 is connected to a dust removal chamber 3 installed on the second floor through a pipeline, and the inner wall surfaces on both sides of the dust removal chamber 3 are respectively provided with perforated plates 19 for dust overflow and purified air discharge.

[0030] Example 1

[0031] The flower hole plate 19 on one side is provided with a shutter 20 on the outer wall surface of the dust removal chamber 3. An ultrasonic excitation atomization mechanism for dust purification is provided in the middle of the inner cavity of the dust removal chamber 3. The ultrasonic excitation atomization mechanism includes a plurality of sprayers 1 27 for generating ultrafine water mist and a plurality of sprayers 2 23 for generating dry mist. The plurality of sprayers 1 27 and sprayers 2 23 are symmetrically arranged and move in opposite directions. An expansion hole 21 is provided on the surface of the flower hole plate 19. An anti-drip mechanism is provided on the inner wall surface of each flower hole plate 19. The middle of the inner cavity of the dust removal chamber 3 is fixed. Two fixed columns 24 are fixedly installed, and a plurality of collars 25 are rotatably sleeved on the outer surface of each fixed column 24. A connecting rod 26 is arranged between two adjacent collars 25 on the same fixed column 24. A tooth block is arranged on the outer surface of the collar 25 at the end. A gear meshing with the tooth block is arranged between two adjacent fixed columns 24. The gear drives the two collars 25 at the end with the tooth block. The collars 25 rotate on the fixed column 24, and due to the connection of the connecting rod 26, multiple collars 25 on the same fixed column 24 can rotate. The rings 25 rotate simultaneously, and the dust particles enter the settling chamber 1 through the exhaust of the dust removal fan of the drying equipment. The large particles of dust settle by their own weight in the settling chamber 1, and the small particles of dust and flocculent dust pass through the exhaust holes and follow the pipeline to one of the perforated plates 19, and overflow from the perforated plate 19 into the dust removal chamber 3. The multiple sprayers 1 27 and the multiple sprayers 2 23 spray out ultrafine water mist below 30 microns and dry mist below 10 microns respectively, and the small particles of dust and flocculent dust pass through the ultrafine water mist and dry mist areas in turn. When the water mist particles collide with the fine particles in the dust, due to the inertia relationship, the particles of different sizes and densities will deflect and change speed to different degrees after the collision, resulting in impact and friction, and gradually condense into larger water droplets, and finally form particles whose weight exceeds the carrying capacity of the air and settle down, effectively absorbing the dust suspended in the air to achieve the dust suppression effect. The purified air is discharged into the atmosphere from the shutter 20, and multiple sprayers 1 27 and multiple sprayers 2 23 can move at the same time to change the spray range and improve the dust reduction effect.

A drainage channel 29 is arranged between the upper and lower inclined water retaining bars 22, and the water outlet of the lower inclined water retaining bar 22 is connected to a water storage tank 5 through a pipeline. The water storage tank 5 is arranged on one side of the dust removal chamber 3. Small particles of dust and flocculent dust overflow from the expansion hole 21 on the perforated plate 19 on one side. After the spraying of ultrafine water mist and dry mist, the small particles of dust and flocculent dust are bonded to each other with the water mist, aggregated and enlarged, and weighted and settled. The water mist attached to the perforated plate 19 drips along the arrangement direction of the inclined water retaining bars 22, so as to avoid the direct dripping of mist water to cause the ground to be wet and the waste of water resources. The dust is intercepted by the interception net 28 to avoid the entry of dust. The dripping mist water enters the water storage tank 5 through the pipeline for reuse.

[0033] A water vapor distributor 4 is installed on the top surface of the dust removal chamber 3, and the water vapor distributor 4 is connected to the sprayer 1 27 and the sprayer 2 23 respectively. The water vapor distributor 4 is connected to a dry fog machine, and the dry fog machine is connected to an external water source and an air source to realize the water vapor distribution of the ultrafine water mist and dry fog of the sprayer 1 27 and the sprayer 2 23.

A sleeve 32 that rolls with the slide seat 35 is fixed on the outer wall surface of the frame plate. The sleeve 32, the arc rod 31 and the rotating end of the limit plate 34 are at the same center of a circle. A spring 33 of an arc structure is sleeved on the outer surfaces of the sleeve 32 and the arc rod 31, and the end surface of the sleeve 32 is provided with The limiting hole 36 that matches the socket is initially fixed to the limiting hole 36 and the socket by means of a hand-tightened fastener, so as to fix the arc rod 31 and the sleeve 32, and the spring 33 is in a tensioned state. Then the movable shelf 6 is pushed to the bottom of the dust collecting port 30, and the frame plate is ensured to fit the dust collecting port 30. After that, the fixing restriction of the arc rod 31 and the sleeve 32 is released, and the spring 33 restores its deformation. The arc rod 31 drives the slide seat 35 to roll in the sleeve 32, and the limiting plate 34 and the frame plate are rotated 90 degrees so that the limiting plate 34 is more tightly connected to the dust collecting port 30, thereby avoiding the displacement of the movable shelf 6 and ensuring the stability of dust collecting.
