Description

Technical Field

[0001] This utility model relates to the technical field, specifically to a kiln exhaust gas treatment device. Background Technology

[0002] During the operation of industrial kilns, a large amount of waste gas containing dust, harmful gases, and incompletely burned particles is generated. If this waste gas is discharged directly without effective treatment, it will cause serious pollution to the atmospheric environment, leading to environmental problems such as smog and acid rain, endangering human health, and violating increasingly stringent environmental protection regulations. Currently, in the field of kiln waste gas treatment, cyclone dust collectors are a commonly used filtration device. Cyclone dust collectors utilize centrifugal force to separate dust particles from the airflow during the rotation of dust-laden gas due to the large centrifugal force, thereby achieving dust collection and removal.

[0003] Currently, single-stage cyclone dust collectors on the market have relatively fixed processing capacity. They have a certain separation effect on large-diameter dust particles, but their collection efficiency for small-diameter dust particles is extremely low. Moreover, single-stage treatment cannot be targeted according to the different particle sizes and characteristics of dust particles, making it difficult to achieve the ideal dust removal effect. Therefore, a kiln exhaust gas treatment device is proposed to solve the above problems. Utility Model Content

[0004] In view of the shortcomings of the prior art, this utility model provides a kiln exhaust gas treatment device, which has the advantages of good purification effect and strong practicality, and solves the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a kiln exhaust gas treatment device, comprising a frame, a collection box disposed inside the frame, and a first treatment mechanism and a second treatment mechanism disposed inside the frame; The first processing mechanism includes a first processing cylinder fixedly connected to the inside of the frame. The bottom of the first processing cylinder has a first discharge port and an air inlet pipe is fixedly connected to one end. The inside of the first processing cylinder is fixedly connected to a first extension pipe. The top of the first processing cylinder is fixedly connected to a driving component. One end of the driving component is fixedly connected to a connecting pipe, and the connecting pipe communicates with the second processing mechanism.

[0006] Furthermore, the drive assembly includes a shroud fixedly connected to the top of the first processing cylinder, a motor fixedly connected to the top of the shroud, and blades fixedly connected to the outer surface of the motor output shaft.

[0007] Furthermore, the shroud is connected to the first extension pipe.

[0008] Furthermore, the second processing mechanism includes a second processing cylinder fixedly connected inside the frame. The bottom of the second processing cylinder has a second discharge port, and the top is hinged with a sealing cover. A locking component is provided on one side of the sealing cover. An air outlet pipe is fixedly connected to the top of the sealing cover. A second extension pipe is fixedly connected inside the second processing cylinder, and a baffle is fixedly connected inside the second processing cylinder.

[0009] Furthermore, the baffle is arc-shaped and has a leakage hole inside, and the baffle is located at the air outlet of the connecting pipe.

[0010] Furthermore, the locking assembly includes a connecting piece fixedly connected to the top of the sealing cover, a threaded rod hinged to one end of the second processing cylinder, a locking nut threadedly connected to the outer surface of the threaded rod, and a notch opened inside the connecting piece.

[0011] Compared with the prior art, the technical solution of this application has the following beneficial effects: 1. The kiln exhaust gas treatment device, with its multi-stage dust removal mode combining the first and second treatment mechanisms, can classify and treat dust particles of different sizes, significantly improving dust removal efficiency. In the first treatment mechanism, exhaust gas enters the first treatment cylinder through the inlet pipe. The strong suction generated by the drive component causes the exhaust gas to form a specific airflow inside the cylinder. Larger dust particles fall into the collection box through the first outlet under the action of gravity and centrifugal force, achieving preliminary separation of coarse dust particles. The first extension pipe extends the residence time of exhaust gas in the first treatment cylinder, enhancing the preliminary dust removal effect.

[0012] 2. In this kiln exhaust gas treatment device, the exhaust gas treated by the first treatment mechanism enters the second treatment mechanism through a connecting pipe. Inside the second treatment cylinder, an arc-shaped baffle with perforations is located at the air outlet of the connecting pipe. When the exhaust gas impacts the baffle, the airflow direction and speed change, causing the remaining dust particles in the exhaust gas to fully collide and adhere to the baffle and the inner wall of the second treatment cylinder. At the same time, the perforation design allows some airflow to pass through, further increasing the contact opportunity between dust particles and the treatment environment, achieving deep capture of fine dust particles. This multi-stage dust removal method is progressive and can more thoroughly remove dust particles from the exhaust gas, enabling the emitted exhaust gas to reach a higher purification standard and effectively reducing environmental pollution.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1-5 The kiln exhaust gas treatment device in this embodiment includes a frame 1, a collection box 4 inside the frame 1, and a first treatment mechanism 2 and a second treatment mechanism 3 inside the frame 1.

[0017] Secondly, the first processing mechanism 2 includes a first processing cylinder 201 fixedly connected inside the frame 1. The bottom of the first processing cylinder 201 is provided with a first discharge port 202 and an air inlet pipe 203 is fixedly connected to one end. The inside of the first processing cylinder 201 is fixedly connected with a first extension pipe 204. The top of the first processing cylinder 201 is fixedly connected with a drive assembly 205. One end of the drive assembly 205 is fixedly connected with a connecting pipe 206, and the connecting pipe 206 communicates with the second processing mechanism 3.

[0018] The multi-stage dust removal mode, which combines the first processing unit 2 and the second processing unit 3, can classify and process dust particles of different sizes, significantly improving dust removal efficiency. In the first processing unit 2, the exhaust gas enters the first processing cylinder 201 through the inlet pipe 203. The strong suction generated by the drive component 205 causes the exhaust gas to form a specific airflow in the cylinder. Under the action of gravity and centrifugal force, larger dust particles fall into the collection box 4 through the first outlet 202, realizing the initial separation of coarse dust particles. The setting of the first extension pipe 204 prolongs the residence time of the exhaust gas in the first processing cylinder 201, enhancing the initial dust removal effect.

[0019] Secondly, the drive assembly 205 includes a shroud 2051 fixedly connected to the top of the first processing cylinder 201. The shroud 2051 is connected to the first extension tube 204. A motor 2052 is fixedly connected to the top of the shroud 2051. A blade 2053 is fixedly connected to the outer surface of the output shaft of the motor 2052.

[0020] The unique design of the drive assembly 205 plays a crucial role in airflow organization. The fan shroud 2051 is fixedly connected to the top of the first treatment cylinder 201 and communicates with the first extension pipe 204. The motor 2052 drives the blades 2053 to rotate, generating a powerful and stable airflow. This design can precisely control the flow state of the exhaust gas within the device, ensuring that the exhaust gas enters the first treatment cylinder 201 evenly and forms an orderly rotating airflow within the cylinder, thereby improving the separation efficiency of dust particles and airflow.

[0021] Meanwhile, the rational airflow organization avoids short-circuiting and turbulence, ensuring that the exhaust gas can pass through each stage of the treatment mechanism in sequence according to the predetermined path, so that each stage of treatment can play its full role and further enhance the overall dust removal efficiency. Compared with traditional dust removal equipment, this device can make more effective use of treatment space and energy by optimizing airflow organization, achieving higher exhaust gas treatment capacity and better dust removal effect.

[0022] Furthermore, the second processing mechanism 3 includes a second processing cylinder 301 fixedly connected inside the frame 1. The second processing cylinder 301 has a second discharge port 306 at its bottom and a sealing cover 302 hinged to its top. A locking component 303 is provided on one side of the sealing cover 302. An air outlet pipe 304 is fixedly connected to the top of the sealing cover 302. A second extension pipe 305 is fixedly connected inside the second processing cylinder 301, and a baffle 307 is fixedly connected inside the second processing cylinder 301. The baffle 307 is arc-shaped and has a leakage hole inside. The baffle 307 is located at the air outlet of the connecting pipe 206.

[0023] After being treated by the first treatment unit 2, the exhaust gas enters the second treatment unit 3 through the connecting pipe 206. Inside the second treatment cylinder 301, an arc-shaped baffle 307 with perforations is located at the air outlet of the connecting pipe 206. When the exhaust gas impacts the baffle 307, the airflow direction and speed change, causing the remaining dust particles in the exhaust gas to fully collide and adhere with the baffle 307 and the inner wall of the second treatment cylinder 301. At the same time, the perforation design allows some airflow to pass through, further increasing the contact opportunity between dust particles and the treatment environment, achieving deep capture of fine dust particles. This multi-stage dust removal method is progressive and can more thoroughly remove dust particles from the exhaust gas, enabling the emitted exhaust gas to reach higher purification standards and effectively reducing environmental pollution.

[0024] Each stage of dust removal in this device has its specific processing function and parameter range. When the concentration, particle size distribution, or flow rate of dust particles in the exhaust gas changes, the dust removal mechanisms at each stage can coordinate and cooperate to adjust the processing strategy. For example, when the content of coarse dust particles in the exhaust gas increases, the first processing mechanism 2 can quickly separate most of the coarse particles, reducing the burden on the second processing mechanism 3; while when the amount of fine dust particles in the exhaust gas increases, the baffle 307 and special structural design of the second processing mechanism 3 can better exert the deep capture effect. In addition, the device has a reasonable structural design and tight connections between components, which can effectively prevent exhaust gas leakage, ensure the stability and reliability of the device during long-term operation, and reduce the risk of production interruption due to equipment failure.

[0025] Additionally, the locking assembly 303 includes a connecting piece 3031 fixedly connected to the top of the sealing cover 302, a threaded rod 3032 hinged to one end of the second processing cylinder 301, a locking nut 3033 threadedly connected to the outer surface of the threaded rod 3032, and a notch opened inside the connecting piece 3031.

[0026] The top of the second processing cylinder 301 is hinged with a sealing cover 302. When it is necessary to clean the dust accumulated inside the second processing cylinder 301 or to perform equipment maintenance, the sealing cover 302 can be opened for convenient operation. The sealing cover 302 is fixed by the cooperation of the connecting piece 3031, the threaded rod 3032 and the locking nut 3033, which not only ensures the sealing of the equipment during operation and prevents exhaust gas leakage, but also facilitates quick opening and closing, greatly shortening the cleaning and maintenance time.

[0027] The working principle of the above embodiments is as follows: (1) The kiln exhaust gas treatment device, with the multi-stage dust removal mode combining the first treatment mechanism 2 and the second treatment mechanism 3, can classify and treat dust particles of different sizes, which significantly improves the dust removal efficiency. In the first treatment mechanism 2, the exhaust gas enters the first treatment cylinder 201 through the air inlet pipe 203. The strong suction generated by the drive component 205 causes the exhaust gas to form a specific airflow in the cylinder. Under the action of gravity and centrifugal force, larger dust particles fall into the collection box 4 through the first discharge port 202, realizing the initial separation of coarse dust particles. The setting of the first extension pipe 204 extends the residence time of the exhaust gas in the first treatment cylinder 201, enhancing the initial dust removal effect.

[0028] (2) In this kiln exhaust gas treatment device, the exhaust gas after being treated by the first treatment mechanism 2 enters the second treatment mechanism 3 through the connecting pipe 206. Inside the second treatment cylinder 301, the arc-shaped baffle 307 with a hole is located at the air outlet of the connecting pipe 206. When the exhaust gas impacts the baffle 307, the airflow direction and speed change, so that the remaining dust particles in the exhaust gas fully collide and adhere to the baffle 307 and the inner wall of the second treatment cylinder 301. At the same time, the design of the hole allows some airflow to pass through, further increasing the contact opportunity between dust particles and the treatment environment, and realizing the deep capture of fine dust particles. This multi-stage dust removal method is progressive and can more thoroughly remove dust particles in the exhaust gas, so that the exhaust gas reaches a higher purification standard and effectively reduces the pollution to the environment.
