A tunnel wet swirl intelligent green dedusting device of the present utility model, when in use, first pour clean water into the secondary filter bucket, start the fan, high-pressure water pump and motor circuit, the fan sucks the dust into the mixing cylinder, and the high-pressure water pump The clean water is injected into the atomizing nozzle through the water inlet pipe, and then atomized through the atomizing nozzle. The atomized water and dust are combined to form a dust mixture, which falls into the mixing cylinder under the action of gravity, and the cleaned gas is discharged through the escape hole. Complete air filtration, effectively remove dust and improve dust removal efficiency.

2. In the tunnel wet swirling intelligent green dust removal device of the present utility model, the dust mixture enters the mixing cylinder at a certain speed, and is forced to make a rotary motion after encountering the wall of the spiral shaft. Due to the different centrifugal forces, the dust in the mixture Coarse solid particles are subjected to a large centrifugal force, which can overcome hydraulic resistance and move toward the wall, and under the joint action of their own gravity, move downwards along the wall in a spiral manner, while fine and small particles and most of the water are affected by the centrifugal force. The centrifugal force is small, and the mixture will make a rotary motion before it gets close to the wall of the container. Under the push of the subsequent mixture, the mixture will continue to move downward and rotate, so the coarse particles continue to concentrate toward the periphery, while the fine particles stay in the central area. The particle size becomes larger and larger from the center to the wall, forming a layered arrangement. As the mixture flows from the cylindrical part of the screw shaft to the cone part, the flow section becomes smaller and smaller. The inner mixture of fine particles has to change direction and move upwards to form an internal swirl flow, which is discharged from the upper drain pipe and becomes an overflow, while the coarse particles continue to spiral downward along the wall of the vessel to form an external swirl flow, and finally It is discharged from the sand outlet and becomes grit, which can effectively separate the dust mixture.

3. In the tunnel wet swirl intelligent green dust removal device of the present utility model, the overflowing mixture enters the first-stage filter barrel through the upper drain pipe, and the first-stage filter barrel is covered with the first filter layer with a coarser particle size, and the first filter The layer is activated carbon and fine sand, etc., which can filter the small particles of the mixture. The filtered water of the first type enters the secondary filter barrel through the bottom drain pipe, and the secondary filter barrel is low in and high out. Two filter layers, the second filter layer is filter cotton and semi-permeable membrane. At this time, the filtered water has reached the spray standard and can be recycled through the high-pressure water pump, which is convenient and energy-saving, and conforms to the concept of green dust removal.

working principle:

First, pour clean water into the secondary filter bucket 7, start the fan 3, the high-pressure water pump 4 and the motor circuit, the fan 3 sucks the dust into the mixing cylinder 2, and the high-pressure water pump 4 injects clean water into the atomizing nozzle 13 through the water inlet pipe 5, and then Atomization is carried out through the atomizing nozzle 13, the atomized water is combined with dust to form a dust mixture, which falls into the mixing cylinder 2 under the action of gravity, and the cleaned gas is discharged through the escape hole to complete air filtration and effectively remove dust. Improve dust removal efficiency;

Secondly, the dust mixture enters the mixing cylinder 2 at a certain speed, and is forced to make a rotary motion after encountering the wall of the screw shaft 12. Due to the different centrifugal force, the solid coarse particles in the mixture are subjected to a large centrifugal force, which can overcome the hydraulic force. The resistance moves to the wall of the container, and under the joint action of its own gravity, it moves downwards along the wall of the container in a spiral manner. The fine and small particles and most of the water will rotate with the mixture before they get close to the wall due to the small centrifugal force. Movement, driven by the continuous increase of the subsequent mixture, the mixture continues to move downward and rotate, so the coarse particles continue to concentrate toward the periphery, while the fine particles stay in the central area, and the particle size becomes larger and larger from the center to the wall. A layered arrangement is formed. As the mixture flows from the cylinder part of the screw shaft 12 to the cone part, the flow section becomes smaller and smaller. Under the contraction and compression of the outer layer mixture, the inner layer mixture containing a large number of fine particles has to change direction. The upward movement forms an internal swirling flow, which is discharged from the upper drain pipe 9 and becomes an overflow, while the coarse particles continue to spiral downward along the wall of the vessel to form an external swirling flow, and are finally discharged from the sand discharge port to become a settling sand. Effectively separate the dust mixture;

The first filter layer 14 is activated carbon and fine sand, etc., which can The small particles of the mixture are filtered, and the filtered first-class filtered water enters the secondary filter bucket 7 through the bottom drain pipe 8. The secondary filter bucket 7 enters low and high, and the second filter layer 15 with a smaller filter diameter is built in. The filter layer 15 is a filter cotton and a semi-permeable membrane. At this time, the filtered water has reached the spraying standard and can be recycled by the high-pressure water pump 4, which is convenient for energy saving and meets the concept of green dust removal.
