The fog beam emitted by the three-stage atomization far-emission gun assembly 1 is in a solid cone shape, and the cone angle is 15-20 degrees.
Principle and workflow of three-stage atomizing long-range gun assembly 1:
the primary atomizing fluid sprayed out of the primary atomizing nozzle 1.2 is injected into the aerosol converging cavity 1.1.6, compressed gas is injected into the aerosol converging cavity 1.1.6 from the air nozzle 1.4, and the two are converged, so that fog particles of the primary atomizing fluid are impacted, rubbed, crushed and disintegrated, the potential energy of the smaller fog particles is enhanced again, and the pressure in the aerosol converging cavity 1.1.6 is further increased, so that the secondary atomization is realized; due to the structural design and parameter setting of the aerosol converging cavity 1.1.6, the self-carried pressures of two fluids, namely air pressure and water pressure, can be fully overlapped and then converged into the pipe body of the straight-through circular pipe 1.1.1 positioned in front of the intersection point 1.1.9, and the reasonable diameter length ratio (less than or equal to 1:3) of the pipe body of the straight-through circular pipe 1.1.1 positioned in front of the intersection point 1.1.9 is added, so that the bundling property is enhanced, the ejected aerosol beam is solid cone-shaped, the angle is 15-20 degrees, and when the internal and external pressure mutation occurs at the moment that the aerosol beam is ejected out of the ejection port 1.1.5, the aerosol particles are burst again, the fineness degree of the aerosol particles is achieved, the ratio of the diameter of the water aerosol particles below 40 mu m is higher than 98%, the three-stage atomization is realized, the fineness aerosol particles are farther in the travel distance from top to bottom, the retention time is longer, the coverage dispersion range is wider, and the density of the unit space is higher;
The smaller the angle beta 1 is, the smaller the flow rate loss of the atomized fluid in the pipe body of the straight-through circular pipe 1.1.1 positioned in front of the intersection point 1.1.9 is, and the larger the angle is, the larger the flow rate loss of the atomized fluid in the pipe body is;
because the through circular tube path 1.1.11 is far larger than the aperture of the water primary atomization nozzle spray orifice 1.2.1 and the air nozzle spray orifice 1.4.1, when the water primary atomization fluid sprayed by the water primary atomization nozzle 1.2 is injected into the air fog converging cavity 1.1.6, and the air nozzle 1.4 is opened and no compressed air is injected, the potential energy of the water primary atomization fluid mostly faces to the direction of the spray orifice 1.1.5, the flow speed of the atomization fluid in the tube body of the through circular tube 1.1.1 positioned in front of the intersection point 1.1.9 is increased, at the moment, the siphon phenomenon occurs in the tube body of the through circular tube 1.1.1 positioned behind the intersection point 1.1.9, and the water primary atomization fluid can not flow backwards; similarly, when compressed gas is injected into the gas mist converging cavity 1.1.6 through the gas nozzle 1.4, and water primary atomization nozzle 1.2 is opened and no water mist is injected, siphoning phenomenon is also generated in the inclined circular pipe 1.1.2, and the gas cannot flow into the inclined circular pipe 1.1.2 laterally and backwards;
the larger the water inlet pressure is, the stronger the siphon in the pipe body of the straight circular pipe 1.1.1 positioned behind the cross point 1.1.9 is, and the higher the air inlet pressure is, the stronger the siphon in the inclined circular pipe 1.1.2 is;
The three-stage atomization long-range gun assembly is suitable for the conditions that the air inlet pressure is greater than 0.4Mpa, the water inlet pressure is greater than 0.3Mpa, the air water is not required to be regulated in the pressure range, the air and water pressure difference limitation is avoided, and the two fluids are not in series flow inside the three-stage atomization long-range gun assembly 1; in addition, according to the condition that the water quality is poor in the mine, special internal structural design and parameter setting are carried out on the assembly main body 1.1, the smooth diameter is increased, the air-water circulation redundancy space is large, the assembly main body 1.1 has an internal cyclone self-cleaning function, the inner cavity is not scaled, in addition, the barrel type spraying mode and the built-in and external filter double-layer protection are adopted, and the three-stage atomization far-emission gun assembly 1 cannot be blocked.
The jet orifice 1.1.5 is a thin edge orifice with the annular vertical plane edge thickness d <0.5mm, and the jet orifice 1.1.5 is an inner circular truncated cone type jet orifice 1.1.5.1 or an outer circular truncated cone type jet orifice 1.1.5.2. Principle and effect: when the gas-fog mixture with the gas-water pressure superposition resultant force passes through the jet orifice 1.1.5 with special structural design, as the thin edge opening does not form a vertical plane 'wind-shielding wall' of the jet direction, vortex of the gas-fog mixture does not appear, water drops are avoided to be formed after the gas-fog mixture stays and loses potential energy, the edge of the jet orifice 1.1.5 goes out of a negative pressure area under the strong bundling effect of the water fog, the gas-fog mixture ejected at high speed still has centripetal force outside the edge of the jet orifice 1.1.5, the fog bundle still keeps cylindrical in a certain length, and no water drop phenomenon exists below the jet orifice.

The water flows through the water flow channel 2.1.4 to be magnetized, the water system property is changed, the water body is softened, the surface tension is reduced, the viscosity is reduced, the atomization degree of the water is improved, the contact probability with dust is increased, and particularly the capturing capability of absorbing dust is enhanced. Because of strong wettability of magnetized water and strong adsorption capacity, the dust falling speed is accelerated, and the dust removal rate is obviously improved.
