Description

The invention relates to devices for cleaning dust from dust and can be used in any industry.

The purpose of the invention is to increase the efficiency of gas cleaning from fine dust.

Lig.1 shows a schematic cyclone apparatus, side view, section; PA figure 2 - the same, top view; in fig-. 3 - irrigation system in a perspective view.

The cyclone machine includes a twisting device 1, a housing 2 with a tangential inlet 3 and an axial exhaust pipe 4. The lower part of the housing 2 is made in the form of a reverse cone 5. The exhaust pipe 4 has a conical insert 6, on the surface of which is made a screw; 7 alternating, 151G1It llocegos

downward, section with flared upper edge inward insert. The cross section of the screw target 7 and the exhaust pipe 4 are of equal size. In the exhaust pipe 4, an irrigation system is installed along the axis, including a supply pipe 8, a rotary stuffing box 9, distribution pipes 10 and sprinklers 11. Distribution pipes 10 are rigidly connected to the brackets 12, on which guide vanes 13 are fixed. the system, the brackets 12 and the guide vanes 13 are installed with one-side rotation possibilities. The guide vanes 13 are placed by the body 2 and the exhaust pipe 4. The sprinklers 11 and the guide vanes 13 are of the prapigs, and the direction of the tightening of the limpan slits 7 is made along the flow path. Bottom part of the konuspg: -., Inserts 6

The device works as follows

The dusty air through the inlet 3 and the swirling device Bo 1 enters the cavity of the housing 2, where it exerts pressure on the surface of the blades 13. This pressure brings the blades to the rotational dash-hepee, and the blades also act as a speed redistributor.

Parts 1 and 51 of large and medium Lractions (more than 10 microns) under the action of aerodynamic (vortex mechanical) and gravitational forces are separated from the flow of ventilation air in the dry dust collecting zone, and particles of small fractions (up to 10 microns) due to stable aerodynamic parameters of vortex air movement in the device either precipitated like large and medium particles, or fall into the cone insert 6 (wet dust collection area), where due to similar flux flows intensively interact with dispersed droplets bone and are separated from the gate - insulating air.

Those particles that continue to double up with the air flow around the exhaust pipe fall into the zone of action of the cone insert 6. R vortex zone due to low pressure inside the insert 6 and the shape of target 7 on its surface carry dust particles into the internal cavity of the insert 6, where the rotation of the sprinklers 11 creates an evenly distributed stream of fine droplets and they interact intensively with the particles of the spray. Retaining the properties associated with the redistribution of velocities, the guide vanes 13, rigidly connected to the irrigators 11, allow the rotational motion of the latter to be organized with minimal energy consumption, which

In the area of dry dust collection, the upper edge of the screw target 7, made on the surface of the insert, is sifted inside the latter.

The efficiency of dust cleaning in the proposed apparatus in fine fractions of expanded clay pypi (c1 / 10 µm) in comparison with the known apparatus increases by 17% (to 91.5%). At the same time, the integrated efficiency of the purification plant reaches 99.7%, which is 5.3% better than that of the known apparatus. Studies conducted for other types of construction dust (perlite, limestone, crushed stone, sand) confirmed the presence of the above effects.
