1 is a perspective view showing the structure of a cyclone separator according to a first embodiment of the present invention, Figures 2 and 3 are a front view and a plan view of the cyclone separator shown in FIG. In addition, Figures 4a to 4c is a view showing various embodiments of the dust guide member shown in FIG.

1 to 3, the cyclone separator according to the first embodiment of the present invention, the body 100, the separator 300 disposed below the body 100, and the body 100 It includes a first guide member 200 located inside.

The body 100 has a cyclone shape in which the radius is narrowed toward the lower portion so as to maintain a constant speed even in the lower portion by reducing the decrease in flow rate as the material flowing while descending the lower the turning length is longer toward the lower portion It is. Here, the inlet 110 is formed so that the body 100 is introduced while forming a swirl flow in which materials formed of fluids or solids having different densities descend, and discharge the first material having a lower density among the materials. The outlet 120 is formed, and the outlet 130 is formed in the lower portion of the second material having a higher density.

The inlet 110 is formed on the upper side of the body 100 so that the first and second materials pivot along the circumferential direction of the body 100. The outlet 120 is formed in a direction perpendicular to the upper center of the body 100 to discharge the first material rising in the body 100, the outlet 130 is the second material It is formed in the lower portion of the body 100 to be discharged by falling.

Meanwhile, in the embodiment of the present invention, the first material and the second material are air and dust (dust), respectively, but other seawater and petroleum may be used, and other materials having different densities may be variously applied.

The separator 300 is disposed below the body 100 and serves to contain the second material introduced from the outlet 130.

The first guide member 200 is disposed in the center of the body 100, the outer shape is formed in a circular curve in the circumferential direction around the axis of rotation of the swirl flow, the second material to pivot Guided to the inner wall of the body 100 to be effectively discharged to the outlet 130.

In this case, the first guide member 200 has a circular cone shape in which the cross-sectional area decreases as it rises from the bottom to the top. This is to make the separation length between the materials having different densities by lengthening the turning length while maintaining a constant flow velocity of the material (air) turning inside the body 100. Accordingly, the first guide member 200 has a cross-sectional area of the lower portion that is relatively larger than that of the upper portion so as to maintain a constant flow velocity of the rotating fluid to facilitate separation of the dense first material (dust). The cross-sectional area induces a smooth rise of the second material (gas, air) having a low density, thereby narrowing the cross-sectional area in order to easily discharge the gas to the outlet 120.

In addition, each embodiment of the present invention has a bar shape (bar), one end is coupled to the inner wall of the body 100 and the other end is coupled to the first guide member 200 to the first guide member 200 It includes a plurality of support members 210 for supporting.

At this time, the reason that the horizontal cross-sectional area of the first guide member 200 is circular is to reduce the interference or vortex of the flow of the fluid turning inside the body 100 to induce the smooth discharge of the gas and dust (1) Because it can. Accordingly, the first guide member 200 may have various shapes such as a cone trapezoidal shape 200a, a shape having a curved outer surface 200b, an inverted trapezoidal shape 200c, and the like. . However, as shown in FIG. 1, the first guide member 200 may have a smaller cross-sectional area as it rises from the lower side to the upper side, and preferably has a circular cone shape.

14 and 15, the cyclone separator according to the comparative example of the present invention includes a cyclone-type body 10 and a separator 20 coupled to a lower portion of the cyclone-type body 10. The cyclone body 10 includes an inlet 11 through which a fluid including dust 1 and a gas flows, and an outlet 12 and dust 1 through which gas flows into the separator 20. A dust outlet 13 is formed to be discharged.

In the cyclone separator according to the comparative example, the fluid is introduced from the upper portion of the cyclone body 10 and is rotated inside the cyclone body 10, and the dust 1, which is provided with centrifugal force, is the cyclone body 10. As the structure collides with the inner wall and discharges into the separator 20, the solid particles having a relatively heavy weight of dust 1 are discharged by falling into the separator 20, but the rising fluid is constant at the center of the body 10. Since the dust collection performance is low due to intermingling without maintaining the mammary gland, the dust collection performance is low, such as the fine dust (1), when the weight is light, the dust is not collected and is discharged together with the gas.

Therefore, as described above, the cyclone separator according to a preferred embodiment of the present invention is provided with a conical first guide member 200 that can improve the dust collection performance in the body, the fluid that is pivoting inside the body It flows along the conical first guide member 200 and guides the dust 1 contained in the fluid to push the inner wall of the body to facilitate the separation of the dust 1 so that only the solid dust 1 having large particles is present. As well as fine dust (1) can be effectively collected.
