Description

Technical Field

[0001] The utility model relates to the technical field of dust removal equipment, in particular to an anti-blocking cyclone separator. Background Technique

[0002] A cyclone separator is a dry gas-solid separation device that uses the centrifugal force generated when a gas-solid mixture rotates at high speed to separate dust from the gas stream. Since the centrifugal force received by the particles is much greater than the gravity and inertial force, the separation efficiency is relatively high. When the dusty gas enters the cyclone separator, the gas flow will change from a linear motion to a circular motion. Most of the rotating gas flow spirally descends along the wall of the cylinder towards the cone from the cylindrical body. In addition, under the action of centrifugal force, the particles are thrown towards the wall of the device. Once the dust particles come into contact with the wall of the device, they lose their inertial force and fall along the wall surface by the momentum of the downward axial velocity near the wall of the device, enter the ash discharge pipe, and fall into the collection bag from the powder outlet. The rotating downward outer swirling gas flow continuously flows into the central part of the separator during the downward process, forming a centripetal radial gas flow, and this part of the gas flow constitutes the rotating upward inner swirling flow, thereby discharging the gas after dust removal.

[0003] In the chemical industry, cyclone separators are also commonly used for gas treatment to separate waste gas containing particulate impurities. However, the particulate matter contained in the waste gas generated in chemical production usually includes microcrystals of chemical reaction substances. After the cyclone separator is used for a long time, these particulate substances containing microcrystals of chemical reaction substances are prone to caking and accumulation at the discharge port of the solid particulate material at the bottom, resulting in blockage of the discharge port of the cyclone separator, affecting the normal discharge and operation of the equipment. At the same time, these accumulated aggregates are very hard and need to be removed manually after the machine is stopped, which is very laborious. Frequent maintenance consumes a large amount of labor costs and production costs, poses potential safety hazards to the operation of the equipment, and seriously affects the long-term stable operation of the device. Content of the Utility Model

[0004] Aiming at the deficiencies existing in the prior art, the utility model provides an anti-blocking cyclone separator, which solves the problems in the prior art that aggregates appear at the discharge port of the solid particulate material, resulting in blockage of the discharge port of the cyclone separator, affecting the normal discharge and operation of the equipment, and being difficult to remove, increasing the labor cost and production cost.

[0005] According to an embodiment of the present utility model, a clogging-proof cyclone separator includes a cylinder body and a cone body coaxially connected up and down in the vertical direction. A medium inlet is provided on one side of the cylinder body along the tangential direction. A discharge pipe is coaxially arranged in the middle of the cylinder body and penetrates upward to the outside. A particle discharge port is opened at the bottom end of the cone body. A flow guiding device is further provided at the bottom of the cone body. The flow guiding device includes a plurality of flow guiding plates. The flow guiding plates are in the shape of a conical cylinder. The inclination degree of the side surface of the flow guiding plate is the same as that of the cone body, so that the flow guiding plates form a coaxially nested structure at the bottom of the cone body, and the bottom discharge ports of the flow guiding plates are correspondingly arranged at the bottom end of the cone body.

[0006] Further, the top heights of all the flow guiding plates decrease in sequence from outside to inside, and the heights of the bottom discharge ports increase in sequence.

[0007] Further, the top position of the flow guiding plate is lower than the height of the middle part of the cone body.

[0008] Further, swirler blades are also arranged between the flow guiding plates and between the inner wall of the cone body and the outermost flow guiding plate. The swirler blades are perpendicular to the flow guiding plates and the side surface of the cone body and are hermetically connected to the surface of the flow guiding plate or the cone body, so as to divide the separation space between adjacent flow guiding plates or between the flow guiding plate and the cone body into upper and lower parts. The swirler blades are arranged in a spiral shape around the central axis of the cone body from top to bottom.

[0009] Further, the flow guiding plates are detachably connected to the cone body and between adjacent flow guiding plates.

[0010] Further, the flow guiding plate or the cone body is detachably connected to the swirler blade.

[0011] Further, a plurality of swirler blades are arranged at equal intervals in the same separation space, and the circumferential angle of the swirler blades around the axial direction of the cone body is less than 60°.

[0012] Compared with the prior art, the present utility model has the following beneficial effects:

[0013] A flow guiding device is provided at the bottom of the cyclone separator in the present utility model. The flow guiding device includes a plurality of conical cylinder-shaped flow guiding plates, and the flow guiding plates form a coaxially nested structure at the bottom of the cone body. Therefore, multiple separation spaces are formed by adjacent flow guiding plates and the inner wall of the cone body. After the gas containing particulate impurities enters the separation space, it will contact both the inner and outer surfaces at the same time. Compared with the traditional cyclone separator that can only contact and rub against the inner wall of the cone body, the efficiency of friction separation of particulate impurities is greatly improved. At the same time, this method divides the bottom of the cone body into smaller spaces, so that the air flow passes through faster. Therefore, the solid particles containing chemical reaction microcrystals are not easy to adsorb and bond between the inner wall of the cone body or the flow guiding plates, and it is more difficult to accumulate and form aggregates, reducing the clogging of the bottom of the cyclone separator.

[0018] The technical solutions in the present utility model will be further described below with reference to the drawings and embodiments.

[0019] As Figure 1 shown, an anti-blocking cyclone separator is proposed in an embodiment of the present utility model, which includes a cylinder body 1 and a conical body 2 coaxially connected up and down in the vertical direction. A medium inlet 3 is provided on one side of the cylinder body 1 along the tangential direction. An exhaust pipe 4 is coaxially arranged in the middle of the cylinder body 1 and penetrates upward to the outside. A particle discharge port 5 is opened at the bottom end of the conical body 2. The airflow is introduced through the medium inlet 3 tangential to the cylinder body 1 and rotates along the cylinder body 1, so that the solid particles with greater inertial centrifugal force are thrown to the outer wall surface and separated. The solid particles slowly sink along the cone and are gradually separated from the gas with the friction with the cylinder body 1 and the conical body 2. The gas rises along the exhaust pipe 4 and reaches the gas outlet to be discharged outside the cylinder body 1, and the solid particles leave the conical body 2 from the bottom.

[0020] As Figure 2 shown, in this embodiment, a flow guiding device 6 is further provided at the bottom of the conical body 2. The flow guiding device 6 includes a plurality of flow guiding plates 61. The flow guiding plates 61 are of a conical cylinder structure. The inclination degree of the side surface of the flow guiding plate 61 is the same as that of the conical body 2, so that the flow guiding plates 61 form a coaxially nested structure at the bottom of the conical body 2, and the bottom discharge ports of the flow guiding plates 61 are correspondingly arranged at the bottom end of the conical body 2. Two layers of flow guiding plates 61 are provided in this embodiment, so as to form three mutually independent separation spaces inside the conical body 2. Preferably, the top heights of all the flow guiding plates 61 decrease in sequence from outside to inside, and the heights of the bottom discharge ports increase in sequence, and the top position of the flow guiding plate 61 is lower than the height in the middle of the conical body 2, so that the spirally descending airflow can enter each separation space more evenly. After the gas containing particulate impurities enters the separation space, it will contact both the inner and outer surfaces at the same time, improving the friction separation efficiency of the particulate impurities. At the same time, the airflow passes through faster and it is more difficult to accumulate and generate aggregates. In addition, the utilization rate of the space in the central area of the conical body 2 is also improved through the flow guiding plate 61.

[0021] As Figure 3 shown, in a further solution of this embodiment, swirl vanes 62 are further provided between the flow guide plates 61, between the inner wall of the vertebral body 2 and the outermost flow guide plate 61. The swirl vanes 62 are perpendicular to the flow guide plates 61 and the side surface of the vertebral body 2 and are hermetically connected to the surface of the flow guide plates 61 or the vertebral body 2, so as to divide the separation space between adjacent flow guide plates 61 or between the flow guide plate 61 and the vertebral body 2 into upper and lower parts. The swirl vanes 62 are arranged in a spiral shape around the central axis of the vertebral body 2 from top to bottom. By the swirl vanes 62, the contact surface of the air flow is further increased, the separation effect of solid particles is improved, and at the same time, the cross-sectional area of the area where the gas can pass through in the separation space is gradually compressed, so that the air flow is further accelerated, and the solid particles are better carried out to avoid accumulation and caking.

[0022] In a preferred solution, a plurality of swirl vanes 62 are arranged at equal intervals in the same separation space, and the circumferential angle of the swirl vanes 62 around the axis of the vertebral body 2 is less than 60°. In this embodiment, eight swirl vanes 62 are arranged in the same layer of separation space, that is, after the air flow enters the separation space, it is divided into eight parts and respectively enters the areas formed by the swirl vanes 62 and the flow guide plates 61 and descends, and is exported from the vertebral body 2 faster.

[0023] Further in this embodiment, the flow guide plates 61 and the vertebral body 2 are detachably connected between adjacent flow guide plates 61. The flow guide plates 61 or the vertebral body 2 and the swirl vanes 62 are detachably connected. Preferably, in this embodiment, detachable bolts are used for connection, which is convenient for replacing and cleaning the flow guide plates 61 or the swirl vanes 62 after wear or caking occurs later.

[0024] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the purpose and scope of the technical solutions of the present invention, and they should all be covered by the scope of the claims of the present invention.
