The foaming rotor 10 rotates rapidly under the action of certain wind power, and free bubbles generated under the action of the wind power fly into the air immediately to capture dust in the air, and finally settle to the ground after being broken, so that a good dust settling effect is realized. In the dust removal process of the tunneling surface, blasting or mechanical cutting and other modes are generally adopted in the tunneling process, and meanwhile ventilation is carried out on the working surface to ensure the safety of operators, so that safety accidents such as dust explosion safety accidents and toxic and harmful gas poisoning are avoided, and the personnel are prevented from being infected with occupational diseases and other hazards. And the dust on the tunneling surface is difficult to dissipate in a short time, so that the working surface is polluted, and the working conditions of other working surfaces are influenced. For this reason, it is common practice for many rock tunnels to stop production after blasting, withdraw all personnel on the face, and resume production after blast smoke and dust have been dissipated. And on-site water curtain dust removal effect is comparatively general, not only needs a large amount of water resources, causes the serious ponding of construction section moreover easily, hinders personnel and equipment to pass through, has caused huge potential safety hazard. According to the current field application situation, the air curtain dust removal technology not only uses huge air quantity, but also consumes a large amount of electric power, and has common effect. In order to achieve the purpose, the free type automatic foaming dust removal device developed by the utility model replaces a water curtain or an air curtain of a construction site with countless monomer bubbles to form a bubble group or a bubble curtain to purify dust. Firstly, according to the field requirement, a bubble curtain is arranged at a certain position away from the tunneling surface. After installing a plurality of free automatic foaming dust collector that assemble, at certain distance department behind the tunnel driving working face, arrange dust collector along tunnel cross-section boundary line here every 500mm to make its foaming dish 11 perpendicular to tunnel cross-section, make the bubble that its produced can fly to the dust that spreads from, also can make the bubble fly for a long time in the air simultaneously, thereby catch more dust. Secondly, according to the actual situation of the dust concentration on site, the number of rows of bubble generators can be increased, the distance between every two rows is 0.5-1m, and three rows are arranged in the scheme, so that the density and the number of bubbles are increased, and the dust removal effect is enhanced. In view of the explosion danger of dust, the speed-adjustable fan can be replaced by an explosion-proof fan or wind pressure on site is used for providing wind power. Then the fan or the air pressure valve is started, the foaming rotor 10 rotates rapidly under the blowing of certain wind power, and generates a large amount of bubbles to fly in the roadway, and at the moment, dust reaching the bubble curtain can be basically intercepted or captured and settled on the ground together with the destruction of the bubbles, so that pollution in other places is avoided. In recent years, air pollution and haze weather of big cities in China increase, and building dust is an important pollution source of the big cities, and is caused by the building dust. When dust is removed on a construction site, generally, measures such as wet operation, canvas covering, spraying and sprinkling are adopted in addition to means of building dust emission, and the effect is obviously improved. The water consumption of the wet operation is large, and the effect is general. In order to better realize the dust removal effect and save water resources, an air purification technology combining spraying and sprinkling with bubble dust removal can be adopted on some construction sites. First, several dust removing bubble generators are arranged in sequence along the dust generating point. Arranging a free type automatic foaming dust removal device at the site along the height of 1.5-2m from the ground every 1-2m, or increasing the density of the arrangement according to the actual requirement of the site. Then, the liquid level detector 21 is used to detect the liquid level of the foam liquid in the liquid containing box 20, and the peristaltic pump 50, the conduit 51, the liquid supply bottle 60 and the conduit 61 are used to deliver the foaming liquid into the liquid containing box 20 at any time, so that the liquid level in the box is always kept at a 'healthy' position. Thirdly, when dust removal is needed, the fan of the free type automatic foaming dust removal device is started to blow the foaming rotor 10, so that bubbles continuously fly out of the foaming disc 11 to capture dust flying in the air. Meanwhile, the bubbles falling on the ground without being destroyed cover the dust source, and further suppress the flying of dust. The visible bubbles can capture the raised dust in the air by dedusting, and can cover the dust generating source at the same time, thereby achieving double effects.

The working principle is as follows: first, the foaming disk 11 and the wind energy converter 12 are sequentially screwed to the rotating shaft 13, and then one side of the wind energy converter 12 is fastened with a nut, thereby assembling a foaming rotor 10. Next, the hollow bolt 31 is installed in the circular hole at the upper end of the bracket 30, and is locked and fixed by a nut, then the foaming rotor 10 is inserted into the hollow bolt 31 on the bracket with one end thereof positioned at one side of the foaming disc 11, and is then locked by a nut, so as to prevent the foaming rotor from falling off during the rapid rotation process, and simultaneously, the foaming rotor is vertically placed into the liquid supply box 20, and the disc surface with 2/3 is exposed out of the box. The hollow bolt and bracket act as a support and fixation axis for the foaming rotor 10 so that the foaming rotor can rotate around the gap screw. Thirdly, the air outlet of the speed-adjustable fan 40 is aligned to the wind energy converter 12 on the foaming rotor 10, and the rotating speed of the foaming rotor is controlled by adjusting the distance between the speed-adjustable fan and the foaming rotor and enabling the wind flow to be perpendicular to the surface of the foaming disk. Fourthly, a proper amount of foaming liquid is poured into the liquid supply box 20 to maintain a certain liquid level, so as to ensure that the foaming holes on the foaming tray 11 are submerged in the liquid. Finally, the speed-adjustable fan 40 is started, the foaming rotor 10 can rotate rapidly under the action of certain wind power, foaming liquid carried by foaming holes in the foaming disc 11 is blown by the wind power to foam and is separated from the foaming disc 11 to fly into the air, meets dust in the air, is adhered, intercepted and captured and then is destroyed, and is deposited on the ground together, so that the purposes of dust removal and air purification are achieved, and when the liquid level in the liquid containing box 20 reaches the alarm limit value of the liquid level detector 21, the peristaltic pump is interlocked to supply liquid.
