AI Technical Summary
In the existing technology, a large amount of smoke and dust is generated during the semi-coke pulverization process, which causes the bag filter to be shut down frequently for backwashing. In addition, the collected dust particles have large differences in size, requiring additional screening and crushing operations.
A collection device including a crusher, a separator, and a dust collector was designed. The crusher uses crushing components to uniformly process the particle size of semi-coke dust in the flue gas. The separator uses changes in airflow velocity to achieve initial settling. The dust collector performs further filtration to ensure that the dust particle size is consistent.
This technology enables continuous collection of semi-coke dust, reduces the downtime frequency of baghouse dust collectors, avoids additional screening and crushing operations, and yields dust products with uniform particle size.

Abstract
Description
Technical Field
[0001] This application relates to the field of dust collection device technology, and in particular to a crushing type collection device for semi-coke dust. Background Technology
[0002] In the existing technology, semi-coke can replace coke (metallurgical coke) and is widely used in chemical, metallurgical, and gasification industries. In order to improve the combustion effect of semi-coke, it is usually made into semi-coke powder and then used as a combustion raw material. However, in the process of making semi-coke powder, a large amount of flue gas mixed with semi-coke powder is generated. In order to reduce the loss of semi-coke powder and air pollution, bag filter dust collectors are usually selected to remove dust from the flue gas containing semi-coke powder, so as to collect the semi-coke powder and restore the air to cleanliness.
[0003] However, due to the large amount of smoke and dust generated during the pulverization of semi-coke, bag filters need to be backwashed frequently, resulting in frequent interruptions in the collection of semi-coke powder and making continuous collection impossible. Furthermore, the collected semi-coke dust particles vary greatly in size, requiring additional screening and crushing processes before it can be used. Utility Model Content
[0004] The problem this application aims to solve is that in the existing process of preparing semi-coke powder from semi-coke, not only does the large amount of semi-coke powder require frequent shutdowns and backwashing of the bag filter, but the large differences in the particle size of the collected dust also require additional screening and crushing operations.
[0005] To solve the above-mentioned technical problems, this application provides a crushing collection device for semi-coke dust, including a separator and a dust collector connected in sequence by pipelines, and a crusher for crushing semi-coke dust in flue gas to uniform particle size. The crusher includes a first cylinder, a motor, a first material tank, a dispersing block, and a crushing component. The first cylinder is arranged vertically in a straight cylindrical shape. The motor is arranged at the top of the first cylinder, the first material tank is arranged at the bottom of the first cylinder, the dispersing block is arranged in the middle position inside the first cylinder, and the crushing component is arranged inside the first cylinder and driven to rotate by the motor.
[0006] Because the collection device of this application is designed with a crusher with a crushing component, it can crush the semi-coke dust in the flue gas through the crushing component, thereby obtaining semi-coke dust with a relatively uniform particle size that does not require subsequent processing. This solves the problem in the prior art that in the process of preparing semi-coke powder from semi-coke, not only does the large amount of semi-coke powder require frequent shutdown and backwashing of the bag filter, but also the large difference in the particle size of the collected dust requires additional screening and crushing operations.

[0014] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. Example
[0015] This application relates to a crushing and collecting device for semi-coke dust, such as... Figure 1-6 As shown, the collection device includes a crusher 1, a separator 2, and a dust collector 3 connected in sequence by pipelines. The crusher 1 is used to crush the collected semi-coke dust to obtain semi-coke dust with relatively uniform particle size. The separator 2 is used to separate the semi-coke dust from the airflow. The dust collector 3 is used to physically filter the semi-coke dust mixed in the separated air, thereby reducing the probability of semi-coke dust being emitted into the air.
[0016] The crusher 1 includes a first cylinder 5, a motor 4, a first material tank, a dispersing block 7, and a crushing component 6. The first cylinder 5 is arranged vertically in a straight cylinder shape and serves as the main container for crushing operations. The motor 4 is located at the top of the first cylinder 5 to provide a power source. The first material tank is located at the bottom of the first cylinder 5 to collect debris that cannot move with the air. The dispersing block 7 is located in the middle of the first cylinder 5 to evenly disperse the incoming semi-coke dust for better crushing. The crushing component 6 is located inside the first cylinder 5 and is driven to rotate by the motor 4 to crush large particles of semi-coke dust into fine particles. The crushed dust passes through the gaps in the crushing component 6 and then enters the separator 2 through a pipeline.
[0017] The separator 2 includes a second cylinder 15 and a second material tank. The second cylinder 15 is a vertically arranged variable-diameter cylinder with a larger diameter at the top than at the bottom. It utilizes the principle of airflow velocity change to promote dust settling. The second material tank is located at the bottom of the second cylinder 15 and is used to collect the preliminarily separated semi-coke dust. After the dust and air mixture enters the separator 2 from the crusher 1, the airflow velocity slows down due to the variable-diameter design of the cylinder. The heavier dust particles settle into the second material tank under the action of gravity, while the lighter air continues to flow upward.
[0018] The dust collector 3 is a bag filter with backwashing function. It is connected after the separator 2. Through the filtration effect of the filter bag, it further captures the fine dust remaining in the air and ensures that the emission gas meets the environmental protection standards.
[0019] The crushing component 6 includes an outer cylinder 9, an inner cylinder 10, and a shaft 8. The outer cylinder 9 is vertically arranged at the top of the first cylinder 5 and is sleeved and connected to the first cylinder 5. The inner surface of the outer cylinder 9 is provided with sharp teeth 11 for crushing. The inner cylinder 10 is coaxially arranged with the outer cylinder 9 and consists of a bottom plate 14, a top plate 12, and wing plates 13. The inner cylinder 10 is a vertically arranged straight cylindrical structure. The top plate 12 is horizontally placed at the top of the inner cylinder 10 and has a notch for the flow of semi-coke dust. The bottom plate 14 is arranged at the bottom of the inner cylinder 10 and is a closed disc structure. The shaft 8 is vertically arranged at the top of the first cylinder 5, with one end connected to the motor 4 and the other end extending into the inner cylinder 10 and fixedly connected to the top plate 12 and the bottom plate 14, for driving the inner cylinder 10 to rotate. The wing plates 13 are evenly and spaced within the inner cylinder. In the circumferential direction between the top plate 12 and the bottom plate 14 of the cylinder 10, there is a gap between the wing plates 13 that serves to screen the particle size of the semi-coke dust. The outer surface of the wing plates 13 is also provided with sharp teeth 11 for crushing. When the motor 4 starts, the shaft 8 drives the inner cylinder 10 to rotate. The semi-coke dust enters from the top of the first cylinder 5, and after being evenly dispersed by the dispersing block 7, it enters the space between the outer cylinder 9 and the inner cylinder 10. Due to the rotation of the inner cylinder 10, the sharp teeth 11 on the wing plates 13 collide with the sharp teeth 11 on the inner wall of the outer cylinder 9, breaking the large particles of semi-coke dust. The small particles of semi-coke dust pass directly through the gap between the wing plates 13, while the large particles of dust are broken by multiple collisions between the sharp teeth 11 and finally fall into the pipeline below through the gap to enter the subsequent processing process.
[0020] In operation, a fan located outside the bag filter 3 draws air to create a high-speed negative pressure flow in the crusher 1, separator 2, and dust collector 3. This allows the flue gas containing semi-coke dust to first enter the crusher 1. Impurities in the flue gas that cannot rise with the air are deposited in the first material tank at the bottom for further processing. Impurities that rise with the air are dispersed by the diverter block and then screened and crushed by the crushing component 6 to obtain semi-coke dust with relatively uniform particle size. The flue gas then enters the separator 2 for dust and air separation. The dust is deposited in the second material tank, and the air enters the dust collector 3 for dust filtration. This process yields semi-coke dust with relatively uniform particle size that requires no further processing.
