Description

Reverse combined cyclone separator

Technical Field

The utility model relates to a cyclone technical field particularly, relates to a reverse combination formula cyclone.

Background

The cyclone separator is a common gas-solid separation device in industrial production, dust-containing gas enters the cyclone separator and is converted from linear motion into high-speed rotary motion, and solid particles overcome the streaming resistance under the action of centrifugal force, move to the wall of the separator and are carried into an ash bucket by downstream air flow at the side wall to be separated.

According to the centrifugal separation theory, the cyclone separator utilizes the centrifugal force generated in the rotating process to carry out gas-solid separation. Therefore, the larger the particle size of the solid particles, the greater the centrifugal force to which the particles are subjected, and the easier they are to be separated; conversely, when the particle size is small (generally, the particle size d is less than 10 μm), the centrifugal force to which the particles are subjected is small, the difficulty of trapping the particles is large, and the separation efficiency is low.

Therefore, a new cyclone separator is needed to improve the recovery efficiency of small particles.

In view of this, the present application is specifically proposed.

By limiting the relationship between the above parameters, it is advantageous to improve the separation effect of the reverse combination cyclone 1000.

In summary, the working principle of the reverse combined cyclone separator 1000 can be referred to as follows:

referring to fig. 5, the gas-solid flow direction of the dirty gas entering the reverse combined cyclone 1000 is shown, the dirty gas enters the cylinder 10 through the inlet 11 of the guiding device, the dirty gas rotates downward in the area between the spiral guiding plate 30, the guiding body 20 and the cylinder 10, and is carried to the outlet 12 of the guiding device, such as the first flow stream 1001, by the downward moving gas flow near the inner wall of the cylinder 10, meanwhile, under the action of the centrifugal force, the particles are sorted according to the particle size, the large particles are deflected to the centrifugal side 122 of the outlet, and the small particles are deflected to the centripetal side 121 of the outlet.

The sorted solids are carried by the gas stream through transition section 300 into cyclone separator 200 for rotational movement. Under the action of centrifugal force, most of the solid particles are thrown towards the cylinder wall and are carried by the gas flow moving downwards near the cylinder wall to the separator outlet 221 of the cyclone separator 200, such as the second stream 1002; the separated and purified gas is discharged through the exhaust pipe 400 as a third stream 1003.

In summary, the reverse combined cyclone separator 1000 provided in this embodiment has at least the following advantages:

first, the speed of the small-particle-size solid particles entering the cyclone separator 200 is significantly increased, the large radius of rotation of the cyclone separator can be maintained, the centripetal movement of the cyclone separator is weakened, and the separation efficiency of the small-particle-size solid particles is improved. Specifically, the upper portion of the guide 100 is a straight section 101, the lower portion is a conical section 102, and the guide outlet 12 is disposed at the lower portion of the conical section 102. After entering the guide 100, the solid particles move to the wall surface of the guide 100 under the action of centrifugal force, and the particle size of the solid particles is distributed from the center to the wall surface in the guide 100 from small to large along with the increase of the retention time of the solid particles. The gas-solid two phases move from the straight cylinder section 101 to the conical section 102, the speed of the gas-solid two phases is gradually increased along with the gradual reduction of the diameter of the guider 100, the speed of the gas-solid two phases is regularly distributed from the center to the wall surface in the radial direction in a gradual reduction manner, the speed of the gas-solid two phases is distributed from the centripetal side to the centrifugal side in the outlet in a gradual reduction manner, and the particle size of solid particles is distributed from the centripetal side 121 to the centrifugal side 122 in the outlet in a gradual increase manner.

When the guide 100 is a straight cylinder, the particle size and velocity distribution of the solid particles on the centrifugal side 122 and the centripetal side 121 are substantially the same as those of the present embodiment. The speed of the centrifugal side 122 of the outlet 12 of the all-cylinder type guider is slightly different from that of the embodiment, but the embodiment relates to the speed of the centrifugal side 121 of the outlet 12 of the guider, and the embodiment has a larger speed gradient from the center to the wall surface. The guide body 20 and the spiral guide plate 30 are disposed in the cylinder 10, and the air flow can be forced to move along the spiral guide plate 30.

Due to the design of the flow guide body 20 and the spiral guide plate 30, after the dust-containing gas enters the guide 100, the gas flow moves towards the guide outlet 12 along the spiral direction, so that the flow field distribution is regular, and the sorting of solid particles at the outlet cannot be disturbed. At the same time, the air stream entering the guide 100 will rotate a certain number of revolutions at the design air flow rate and enter the guide outlet 12. Therefore, the guide body 20 and the spiral guide plate 30 are arranged, so that the airflow can move according to the designed number of rotation turns, the retention time of particles is prolonged, and the separation efficiency is increased. The flow is more regular, and the interference of longitudinal short-circuit flow and air volume change is reduced, so that the particle distribution at the outlet 12 of the guider is more regular.

It should be noted that, when there is no internal component in the guider 100, after the dust-containing gas enters the guider 100, part of the gas flow is directly and longitudinally short-circuited to the guider outlet 12 without rotation, so that the flow field distribution is relatively disordered, and the ordering of the solid particles at the outlet is disturbed. Meanwhile, the airflow enters the guider 100 and then enters the guider outlet 12 after rotating for a certain number of turns at the designed gas speed, if the spiral guide plate 30 is not arranged, when the inlet gas amount is changed, the tangential speed and the axial speed of the airflow are changed, the number of turns of the airflow in the guider 100 is changed, and the sorting effect of particles is influenced.

The inlet centrifugal side 202 of the cyclone separator 200 is connected to the outlet centripetal side 121 of the guide 100; the inlet centripetal side 201 of the cyclone separator 200 is connected to the inlet centrifugal side 202 of the guide 100. When the gas-solid two phases enter the cyclone separator 200, the inlet centripetal side 201 of the cyclone separator 200 has larger solid particle size and smaller speed; the inlet centrifuge side 202 has a smaller particle size and a higher velocity of solid particles. After the solid particles enter the cyclone separator 200, although the centripetal speed is low, the particle size of the solid particles is large, and the solid particles can be separated and recovered by the centrifugal force, so that the high separation efficiency is kept. The inlet centrifuge side 202 of the cyclone 200 has a smaller particle size of solid particles but a higher velocity and a larger radius of rotation. The small-particle-size solid particles have higher speed than the full-straight-barrel type guider 100, so that the large rotating radius of the small-particle-size solid particles is kept, the centripetal movement of the small-particle-size solid particles is weakened, and the separation efficiency of the small-particle-size solid particles is remarkably improved.

Second, the velocity of the intermediate size solid particles is significantly increased, allowing them to have a larger radius of rotation within the cyclone separator 200, thereby significantly increasing the intermediate solid particle separation efficiency. Specifically, compared with the all-straight-barrel type guider 100, the present embodiment can also improve the separation efficiency of the solid particles with the middle particle diameter, and the solid particles with the middle particle diameter have smaller centrifugal and centripetal movement amplitude, so that the solid particles are easy to escape finally. Since the lower portion of the guide 100 of this embodiment is tapered, this embodiment has a greater velocity gradient in the centripetal direction and greater velocity at the center than the all-cylinder guide outlet 12. This can not only improve the separation efficiency of the solid particles with the intermediate particle size, but also improve the separation efficiency of the solid particles with the small particle size and the large particle size.

Thirdly, due to the compression effect (space compression and the transition from the right trapezoid to the rectangle at the inlet and the guiding effect of the bevel edge), the rotating radius of the solid particles with large, medium and small particle sizes is increased, and the separation efficiency is improved. Specifically, the deflector outlet 12 configuration further improves separation efficiency. Since the director outlet 12 of this embodiment is a right trapezoid, the separator inlet 211 is rectangular. When transitioning from the right trapezoid waist to the rectangular right-angled edge of the inlet of the cyclone separator 200, the right trapezoid waist may be offset toward the inlet centrifugal side 202, which may further offset the solid particles toward the inlet centrifugal side 202, which may be beneficial to improving the solid particle separation efficiency.

Fourthly, the collision agglomeration effect is enhanced, and the separation efficiency is further improved. When the solid particles are subjected to centrifugal and centripetal motions, the solid particles can be subjected to collision and agglomeration. The solid particles with large particle size can carry the solid particles with intermediate particle size and the solid particles with small particle size to generate centrifugal motion, so that the solid particles with intermediate particle size and the solid particles with small particle size are separated. The mass of the agglomerated solid particles is increased, and the separation efficiency of the solid particles is improved. In this embodiment, the velocity gradient from the centrifugal side 122 to the centripetal side 121 of the outlet 12 is greater than that of a full cylinder, the velocity of the solid particles increases, the degree of collision increases, and the separation efficiency of the solid particles can be further improved. The high level separation efficiency of the solid particles with large particle size is maintained.

The above is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and various modifications and changes will occur to those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
