Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail with reference to the following embodiments. It is to be understood that the specific embodiments described herein are for purposes of illustration only and are not to be construed as limiting the invention, i.e., the described embodiments are merely a subset of the embodiments of the invention, rather than a complete subset.

The spherical column separator is a two-phase separation device for gas-solid or gas-liquid separation, and the structure of the spherical column separator is shown in figure 1, and mainly comprises six parts, namely a gas inlet pipe 1, a gas outlet pipe 2, an upper hemisphere 3, a column section 6, a lower hemisphere 4 and a dust outlet 5.

As shown in figure 1, after the dust-containing gas enters the separator from the gas inlet pipe at a certain speed, the dust-containing gas rapidly rotates downwards between the upper hemisphere and the gas outlet pipe due to the action of the upper sphere structure, and then the part of gas flows downwards. The downward airflow rotates to flow downwards and sequentially passes through the upper ball body and the column section. And then, the circular air column below the exhaust pipe is driven to rotate, when the air flow moves to the end part of the lower hemisphere and can not continue to rotate downwards, the direction is folded and moves upwards along with the air column below the exhaust pipe, and the air flow is called as an upstream flow. In the process of movement of dust-containing gas in the separator, a small part of particles carried by ascending gas flow are discharged from the exhaust pipe, most of solid particles are thrown to the wall surface under the centrifugal action, are discharged from the dust discharge port through the lower ball body along the wall surface, and are collected by the material collecting box.

As can be seen from the movement of the particles in fig. 2, when the dust-laden gas enters the separator, the particles move in a radial direction from the center towards the wall, with a radial velocity directed from the center towards the wall. The resultant force in the radial direction of the large particles is greater than the resistance, so that the resultant force in the radial direction points to the wall surface of the separator, and the large particles move towards the wall surface and are arranged on the outermost layer, such as particles A; the resultant force on the relatively small particles is also small, and the particles are sequentially arranged in the inner layer according to the particle size, such as particles B and C, and the particles rotate downwards. The spherical column separator has the advantages that due to the action of the spherical structure at the upper part, the speed direction of particles is downward inclined, the speed in the radial direction is reduced, the time for moving the particles to the wall surface is increased, and the separation is more thorough; the speed in the axial direction is increased, so that the screw pitch of the particles rotating downwards is increased, the number of rotating turns is reduced, the particles move to the lower ball body of the separator more quickly, the trapping probability is increased, and the upper ball body also reduces the ash ring, thereby being beneficial to improving the separation efficiency. When the particles move from the wall surface of the lower sphere to the dust exhaust port, the radial space of the separator is larger, and the space occupied by the outer cyclone is larger, so that secondary back mixing caused by the swing of the lower part of the ascending air flow is reduced, and the particle separation is facilitated.

It is to be understood that the above description is not intended to limit the present invention, and the present invention is not limited to the above examples, and those skilled in the art may make modifications, alterations, additions or substitutions within the spirit and scope of the present invention.
