Detailed Description

The following describes the present invention with reference to the accompanying drawings. In which like parts are designated by like reference numerals.

It should be noted that the terms "front," "back," "left," "right," "upper" and "lower" used in the following description refer to directions in the drawings, and the terms "inner" and "outer" refer to directions toward and away from, respectively, the geometric center of a particular component.

In order to make the content of the present invention more clearly understood, the technical solution in the embodiment of the present invention will be clearly and completely described below with reference to the attached drawings in the embodiment of the present invention.

As shown in fig. 1 to 3, a low drag high efficiency cyclone separator comprises: the combined air outlet box 2 and the combined cyclone cylinder 5 are combined, an air outlet 1 is arranged at the top end of the combined air outlet box 2, the combined air outlet box 2 is communicated with the combined cyclone cylinder 5 through an exhaust pipe 3, an air inlet 4 is arranged on one side of the combined cyclone cylinder 5, and the bottom end of the exhaust pipe 3 is communicated with a heavy ash settling bin 6.

The combined cyclone 5 is in a parallel double-cyclone structure. The air inlet 4 is communicated with a volute 7, and the volute 7 is communicated with the combined cyclone barrel 5.

Example (b): the diameter of the combined cyclone cylinder is reduced by designing the double-cyclone cylinder structure,

according to the formula of centrifugal force

In the formula: f-centrifugal force, N, obtained by the dust particles;

-angular velocity of rotation of dust particles around the cyclone cylinder axis, rad/s;

r is the distance rotating radius, m, between dust particles and the shaft of the cyclone cylinder;

m-mass of dust particles, kg;

d is the diameter of the dust particle, m;

rho-true density of dust particles, kg/m³；

v is the tangential velocity of the dust particles, m/s.

From the above formula, it can be seen that if the gas speed at the air inlet of the cyclone separator is constant, the smaller the rotation radius of the flue gas is, the larger the true density and size of dust particles are, the larger the centrifugal force is; therefore, the diameter of the cyclone cylinder is properly reduced, and dust particles in the flue gas or larger centrifugal force can be obtained, so that the flue gas can be separated from the flue gas more easily.

The high-temperature high-dust flue gas enters a volute 7 through an air inlet 4 at the speed of 16m/s, then the high-temperature high-dust flue gas is divided into two parts, high-temperature airflow respectively enters a combined cyclone cylinder 5 along the tangential direction, the linear motion of the airflow is changed into circular motion, high-speed spiral airflow is formed in the combined cyclone cylinder, and the high-temperature high-dust flue gas flows downwards towards a cone along the wall of the cyclone in a spiral shape. In addition, the particles are thrown to the wall under the action of centrifugal force, once dust particles contact the wall, the dust particles lose inertia force and fall along the wall surface by the momentum of downward axial velocity near the wall, and then enter the heavy ash settling bin. The outer cyclone air flow which rotates and descends continuously flows into the central part of the cyclone separator in the descending process to form centripetal radial air flow, the air flow forms an inner cyclone which rotates upwards, the rotating directions of the inner cyclone and the outer cyclone are the same, and finally purified air enters the combined air outlet box 2 through the exhaust pipe 3 and is discharged through the air outlet 1.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not intended to limit the present invention, and all modifications, equivalents, improvements and the like that are made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
