Description

Technical Field

[0001] The present invention relates to the technical field of cyclone separation, and in particular to a multi-tube cyclone separation device and a cyclone arrangement method. Background Art

[0002] A cyclone separator is a static device that uses centrifugal force to separate solids from gases or liquids from gases. Its principle is to generate strong centrifugal force through high-speed rotating airflow, which accelerates the sedimentation of particles in the airflow to achieve the separation effect. When the airflow containing particles enters the cyclone separator, the centrifugal force generated by the rotation is much greater than the gravity, so the particles are thrown to the inner wall of the separator and settle along the wall to the bottom under the action of gravity. The purified gas is discharged from the top. The separation efficiency of the cyclone separator is closely related to the airflow speed. The higher the speed, the greater the centrifugal sedimentation speed of the particles, thereby improving the separation effect of solids and gases. Due to its simple structure, no moving parts and easy maintenance, cyclone separators are widely used in industrial dust removal, air purification and gas-solid separation.

[0003] In the prior art, most multi-cyclone separation equipments usually have all cyclones of the same design and are arranged in parallel. The gas containing solid particles enters the hammer-shaped cylinder structure of the equipment along the tangential direction. Through the tangential entry of the airflow, the gas forms a high-speed rotating airflow inside the cylinder, generating a strong centrifugal force. As the airflow rotates, the particles are pushed toward the tube wall by the centrifugal force, collide and gradually rotate and fall along the tube wall, and finally enter the receiving port at the bottom for collection.

[0004] However, the inventors found in the actual application process that some fine particles could not be completely separated from the gas due to insufficient centrifugal force, and would be discharged together with the purified gas, resulting in reduced separation efficiency. Therefore, a more efficient separation device is urgently needed. Summary of the invention

The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation method.

[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0023] like Figures 1 to 11 The multi-cyclone separation device shown comprises a cylinder 1 and a plurality of cyclones 2 .

[0024] The cylinder 1 is a cylindrical structure, with an air outlet 11 at one end and a material outlet 12 at the other end. A first partition 14 and a second partition 15 are fixed in parallel inside the cylinder 1. A accommodating chamber 16 is between the first partition 14 and the second partition 15, and a feed inlet 13 is provided on the side wall of the accommodating chamber 16.

[0025] The cyclone 2 is a cylindrical structure, including a cyclone assembly 21 and an air lift assembly 22. The cyclone assembly 21 includes an air inlet section 21a and a discharge section 21d. The air lift assembly 22 includes a separation section 22a and an air outlet section 22b. The air inlet section 21a is sleeved outside the separation section 22a. The end of the air inlet section 21a is fixedly connected to the air lift assembly 22. The air outlet section 22b passes through the first partition 14. The air inlet section 21a and the discharge section 21d are fixed on the second partition 15. It should be pointed out here that there are many kinds of arrangement orders of the cyclones 2, which can be a matrix arrangement, a ring arrangement, a polygonal arrangement, or a staggered arrangement.

[0026] There is a separation gap 23 between the air inlet section 21a and the separation section 22a, and one or two inlets 21a1 are provided on the air inlet section 21a in the same extending direction as the cyclone 2.

[0027] like Figure 1 , Figure 2As shown, during the operation of the multi-cyclone separation device of the present invention, the gas containing particles enters the accommodating chamber 16 through the feed port 13 on the side wall of the cylinder 1, enters the separation gap 23 in the cyclone assembly 21 through the inlet 21a1 in the air inlet section 21a, and then rotates and separates the gas containing particles through the separation gap 23 and the separation section 22a. A high-speed rotating airflow is formed in the cyclone assembly 21 by entering the separation section 22a through the inlet 21a1. Due to the centrifugal force generated by the rotation, the particles in the gas are quickly thrown to the inner wall of the cyclone 2 and settle to the discharge section 21d along the wall; the purified gas rises in the air lifting assembly 22, and is then discharged through the air outlet 11 at the upper end of the cylinder 1, completing the gas-solid separation process; and the separated particles settle to the discharge section 21d along the wall of the cyclone 2, and are finally discharged from the discharge port 12 at the bottom of the cylinder 1.

[0028] The present invention fixes the cyclone assembly 21 and the air lifting assembly 22 at different positions by means of the first baffle 14 and the second baffle 15 arranged in parallel in the cylinder 1 to form a accommodating chamber 16, thereby enhancing the stability and airtightness of the cyclone separation. The air inlet section 21a, the separation section 22a and the air outlet section 22b are utilized to optimize and control the flow rate and pressure of the airflow at different stages. In particular, a separation gap 23 is provided between the air inlet section 21a and the separation section 22a, which can ensure that the airflow generates a greater centrifugal force during efficient rotation, thereby improving the separation efficiency of fine particles, allowing more fine particles to settle to the bottom and be finally discharged, thereby improving the overall separation effect of the device.

[0029] In some embodiments of the present invention, the two ends of the air inlet section 21a also have a first fixing plate 21b and a second fixing plate 21c arranged parallel to the second baffle 15, the second fixing plate 21c is fixedly connected to the second baffle 15, and the first baffle 14 is fixedly connected to the pipe wall of the air inlet section 21a and the separation section 22a. Figure 2 , Figure 4 , Figure 7 As shown, the supporting effect of the first fixed plate 21b and the second fixed plate 21c enhances the structural stability of the air inlet section 21a and the separation section 22a, reduces the vibration and deviation of the equipment during high-speed rotation, and ensures the uniform entry of the airflow, making the gas separation process more efficient, especially when separating fine particles, improving the separation effect. In addition, the fixed connection between the second fixed plate 21c and the second partition 15, on the one hand, enhances the sealing, reduces the possibility of gas leakage, and maintains the internal pressure and airflow speed; on the other hand, it allows the cyclone 2 to be more stably fixed on the second partition 15.

[0030] Continue to refer Figure 4 , Figure 7As shown, the inlet 21a1 is also provided with a guide plate 21a2, which extends to the outside of the air inlet section 21a, and is tangent to the wall of the cylinder 1, and is fixedly connected to the first fixed plate 21b and the second fixed plate 21c. The addition of the guide plate 21a2 optimizes the entry path of the airflow, allowing the airflow to enter the air inlet section 21a tangentially in a smoother manner, thereby reducing the occurrence of short-circuit flow and improving the stability of the airflow. Secondly, the design of the guide plate 21a2 being tangent to the wall of the cylinder 1 guides the gas to enter the cyclone separation device in the optimal direction, ensuring a more efficient centrifugal separation effect and enhancing the separation efficiency of particulate matter. In addition, the connection between the guide plate 21a2 and the fixed plate increases the overall strength and stability of the structure, reduces vibration and wear during the operation of the equipment, and extends the service life of the device.

[0031] like Fig.10 , Fig.11 As shown, the separation section 22a is also provided with a plurality of slits 22c extending in the same direction as the lift assembly 22, and the slits 22c are evenly arranged in the separation section 22a, and the opening direction of the slits 22c forms an angle with the axis of the lift assembly 22, and the angle is between 30° and 60°. The slits 22c arranged in the separation section 22a can provide an additional discharge channel for gas separation during the rotation of the airflow, which helps to guide the incompletely separated particles to approach the wall surface, further improving the separation efficiency. Secondly, the inclination angle between the opening direction and the axis prompts the gas to produce an upward spiral upward motion while rotating, so that the purified gas after separation enters the lift assembly 22 more smoothly, reducing the airflow resistance. In addition, the design of evenly distributed slits 22c makes the distribution of the airflow more uniform, avoids the turbulence caused by excessive local airflow, and thus enhances the stability of the separation process. It should be pointed out here that the slit cyclones can be installed in different positions according to actual conditions, and can be all slit cyclones, or a combination of cyclones with some without slits and some with slits. It should also be pointed out that there are many ways to arrange the cyclones with slits. They can be arranged horizontally or vertically, in a ring position, in the middle part of the arrangement position, or in the outer position of the arrangement position, etc.

[0032] like Figure 6 , Fig. 9As shown, the slit 22c has two circles. The double-circle slit 22c enables the airflow to be discharged and guided at multiple levels in the separation section 22a, forming a stronger centrifugal force, further prompting the particles to approach the wall and settle, improving the thoroughness of particle separation, and the two-circle slit 22c structure is evenly distributed, which can effectively reduce airflow turbulence and ensure that the airflow maintains a uniform speed and stability during the rotating ascending process. The two-layer slit 22c design enables the purified gas to enter the lifting component 22 more smoothly, reducing the airflow resistance, reducing energy consumption, and improving the separation efficiency and stability of the device. It should be pointed out here that the opening directions of the two circles of slits 22c have many kinds. The directions may be the same as the direction of the inlet 21a1, or the directions may be opposite to the direction of the inlet 21a1. The direction close to the first fixed plate 21b may be the same as the direction of the inlet 21a1, and the direction away from the first fixed plate 21b may be opposite to the direction of the inlet 21a1. The direction close to the second fixed plate 21c may be the same as the direction of the inlet 21a1, and the direction away from the second fixed plate 21c may be opposite to the direction of the inlet 21a1.

[0033] In some embodiments of the present invention, Fig.10 As shown, the opening directions of the two layers of slits 22c are the same. This ensures that the airflow in the separation section 22a flows in the same direction, thereby reducing the disturbance of the airflow when entering the separation section 22a and improving the stability of the airflow. The double layers of slits 22c with the same opening direction form a superimposed centrifugal effect, so that the particles are more evenly stressed in the rotating airflow, which helps the particles to settle on the wall surface, thereby improving the thoroughness and efficiency of the separation. Since the airflow has a consistent path in the entire separation section 22a, energy loss is reduced, so that the purified gas can enter the air lifting component 22 more smoothly, reducing the energy consumption of the equipment and extending the service life of the device.

[0034] In some embodiments of the present invention, Fig.11 As shown, the opening directions of the two layers of slits 22c are opposite. The design of opening in opposite directions forms an alternating airflow path in the separation section 22a, so that the gas generates additional disturbances during the rotation process, which helps to increase the sedimentation frequency of particles on the wall surface, thereby improving the separation effect, making the airflow more evenly distributed in the separation section 22a, and helping to prevent particles from accumulating in a specific area; the alternating airflow path can also disperse the impact force of the airflow on the wall surface, reduce the wear of the equipment, and extend the service life of the device.

[0035] like Figure 3As shown, in some embodiments of the present invention, several cyclones 2 are evenly arranged to form a regular hexagonal layout, and the axial distance between any two adjacent cyclones 2 is 90 mm. The regular hexagonal layout makes the space between the cyclones 2 more compact, which can minimize the overall volume of the device, thereby saving equipment installation space. The uniform axial distance ensures that the airflow distribution between the cyclones 2 is balanced, reduces the possibility of mutual interference between the airflows, and improves the overall separation efficiency. The 90mm spacing setting optimizes the airflow path while avoiding turbulence and backflow between the cyclones 2, which contributes to the stability of the gas-solid separation process. In some embodiments of the present invention, the cyclones arranged in a regular hexagon can set the cyclones with slits in the outermost circle, or set the cyclones with slits in the center. They can also be set based on the analysis of different particle falling conditions.

[0036] In order to make the separated solids be discharged more smoothly, Figure 5 , Figure 6 , Figure 8 , Fig. 9 As shown, the outlet of the discharge section 21d also has a constriction section 22d, and the constriction section 22d is reduced in diameter along the outer wall of the discharge section 21d toward the axial direction of the gas lift assembly 22. The diameter-reducing structure of the constriction section 22d can further accelerate the flow speed of the particles before the particles are discharged, effectively avoiding the accumulation of particles at the outlet, ensuring a smooth discharge process, and the structure of the constriction section 22d forms a local pressure difference at the outlet, further accelerating the sedimentation and discharge of the particles, and helping to separate fine particles more efficiently.

[0037] According to a second aspect of the present invention, a multi-cyclone separation method is also provided. Fig.12 As shown in , the following steps are included: S10: Building a simulation environment of a cyclone separation device in a computer system, and setting an initial arrangement of a plurality of cyclones 2; S20: simulating a process of gas entering the cyclone separation device in a simulated environment, and calculating the separation effect of each cyclone 2 on solid particles in the airflow; S30: Analyze the wear of each cyclone 2 caused by the impact of solid particles according to the simulation result of the settling of solid particles in the discharge port 12 after gas separation, and mark the position of the cyclone 2 with more serious wear; S40: replacing the cyclone 2 that is relatively severely worn with a cyclone 2 having a slit 22c structure; S50: Repeat the above steps to gradually adjust the position and structure of the cyclones 2 until an arrangement of the cyclones 2 with the best separation efficiency and the least wear is obtained.

[0038] refer to Figures 13 to 16As shown, the multi-tube cyclone separation method optimizes the arrangement and separation effect of the cyclones 2 by building a simulation environment in a computer system. First, by simulating the flow and separation process of gas in the device, the influence of different arrangements of the cyclones 2 on the particle separation effect can be analyzed, and the best arrangement can be found to maximize the separation efficiency. Secondly, the method can analyze the wear of the cyclones 2 caused by particle impact, mark the locations with more severe wear, and replace or add slits 22c structures to these cyclones 2 to reduce wear and extend the overall service life of the equipment. In addition, by identifying high-wear areas in advance and optimizing the design, the maintenance frequency and cost of the equipment are significantly reduced. The present invention utilizes the automation characteristics of computer simulation to quickly and accurately adjust and optimize, and through repeated simulations, obtains the solution with the best separation effect and the least wear, thereby improving the overall performance and structural rationality of the device, reducing the need for adjustments in actual operations, and making the equipment more efficient, durable and economical.
