[0002] Dust generated during the dry quenching coke oven production process poses a hazard to operators, and its spread outdoors severely pollutes the environment. Long-term accumulation can lead to equipment wear and tear, reduced production efficiency, and increased maintenance costs. In addition, harmful substances in the dust can cause respiratory diseases and threaten workers' health. Therefore, dust control is crucial in the production process.

[0003] In the existing technology, traditional dust treatment devices consist of connecting pipes, filters, and fixing devices. The connecting pipes are used to transport dust-laden gas, the filters are responsible for intercepting and adsorbing dust particles, and the fixing devices ensure the stable connection of each component. These components work together to filter the dust-laden gas.

[0004] However, in traditional dust treatment devices, the filter screens of the components become clogged after a period of use, requiring manual and regular ash removal. This ash removal process may cause secondary pollution and harm the health of employees. Therefore, this utility model proposes a high-efficiency collection and treatment device for coke dust from dry quenching coke loading to solve the above problems. Summary of the Invention

[0022] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0023] Example 1: Please refer to Figures 1 to 6. This utility model provides a technical solution: a high-efficiency collection and treatment device for coke dust from dry quenching loading, comprising: an induced draft fan 1, with a connecting pipe 2 installed at one end of the induced draft fan 1, and a dust collection box 3 connected to the other end of the induced draft fan 1. The dust collection box 3 has a first dust collection chamber 4 and a second dust collection chamber 5. A coarse filter screen 6 is installed in the first dust collection chamber 4, and a dust collection filter element 7 is installed in the second dust collection chamber 5; a pulse dust collector 8, with a pulse tube 9 installed at one end of the pulse dust collector 8.

[0024] In use, the dust and smoke outlet of the dry quenching coke oven production process can be connected to the connecting pipe 2 at one end of the induced draft fan 1, and the induced draft fan 1 can be started to allow the dust and smoke to enter the dust collection box 3. When the dust and smoke pass through the first dust collection chamber 4, the coarse dust particles in the dust and smoke will be intercepted by the coarse filter screen 6 and fall directly to the bottom, while the fine dust particles will enter the dust collection filter element 7 in the second dust collection chamber 5 and be captured by the dust collection filter element 7. A pulse tube 9 is installed directly above the dust collection filter element 7. The dust collection filter element 7 is periodically cleaned by the pulse dust collector 8 through the pulse tube 9 to prevent clogging. Finally, the clean gas after dust removal is discharged from the top of the dust collection box 3. This avoids the problem of manual ash removal during the dry quenching coke oven production process, which may cause harm to the operators.

[0025] Example 2: Based on Example 1, a first dust collection chamber 4 is provided to reduce the frequency of cleaning the dust collector filter element 7. The first dust collection chamber 4 is located inside the dust collection box 3 near the end of the connecting pipe 12. A first collection frame 14 is fixedly installed at the bottom of the first dust collection chamber 4. A coarse filter screen 6 is fixedly installed on the inner wall of the first dust collection chamber 4. A connecting hole is opened on the side wall of the first dust collection chamber 4 away from the connecting pipe 12. The exhaust fan 1 is fixedly installed on the surface of the support platform 10. Several support feet are fixedly installed at the bottom of the support platform 10. A connecting pipe 2 is fixedly installed on the surface of one end of the exhaust fan 1. An installation plate 11 is fixedly installed on the other end of the exhaust fan 1. The installation plate 11 is fixedly connected to one end of the connecting pipe 12. The connecting pipe 12 has an overall "S" shaped structure. A connecting frame 13 is fixedly installed on the end of the connecting pipe 12 away from the installation plate 11. The connecting frame 13 is fixedly installed on the surface of one end of the dust collection box 3.

[0026] To reduce the frequency of filter element cleaning, the dust and smoke pass through the first dust collection chamber 4 before passing through the dust collection filter element 7. The first dust collection chamber 4 filters out coarse dust particles in the dust and smoke, and discharges them through the first collection frame 14 below, preventing large dust particles from directly entering the dust collection filter element 7 and causing blockage. This extends the service life of the filter element and reduces the frequency of cleaning and maintenance. At the same time, this pretreatment process also helps to improve the efficiency and effect of subsequent fine filtration.

[0027] Example 3: Based on Example 2, a second dust collection chamber 5 is provided to avoid the need for manual ash removal. The second dust collection chamber 5 is located inside the dust collection box 3 at the end away from the connecting pipe 12. A diversion plate 15 is fixedly installed inside the second dust collection chamber 5 at the end near the connecting hole. Several dust collection filter elements 7 are fixedly installed between the diversion plate 15 at the side away from the connecting hole and the second dust collection chamber 5. A second collection frame 18 is fixedly installed directly below the dust collection filter elements 7. A pulse tube 9 is fixedly installed directly above the dust collection filter elements 7. One end of the pulse tube 9 is fixedly installed on the surface of the pulse dust collector 8. The pulse dust collector 8 is fixedly installed on one side surface of the dust collection box 3. An air outlet is opened on the upper surface of the dust collection box 3. An air outlet pipe 16 is fixedly installed directly above the air outlet. The dust collection box 3 is generally rectangular. A square hole is opened at the end of the dust collection box 3 near the connecting frame 13. The square hole is directly opposite the connecting frame 13. Two sets of dust outlet holes 17 are opened at the bottom of the dust collection box 3.

[0028] To avoid the need for manual dust removal, after the dust and smoke pass through the first dust collection chamber 4, they enter the second dust collection chamber 5 through the connecting hole. In the second dust collection chamber 5, under the action of the guide plate 15, the dust and smoke will flow upward from the lower end of the dust collection filter element 7. The fine dust particles in the dust and smoke will be adsorbed on the dust collection filter element 7. Then, the filtered clean gas will be discharged from the exhaust pipe 16 at the upper end of the dust collection box 3. After the dust collection filter element 7 has been used for a period of time, the fine dust particles will clog the dust collection filter element 7. At this time, the pulse dust collector 8 is started and high-pressure gas is quickly injected into the inner cavity of the dust collection filter element 7 through the pulse pipe 9. The instantaneous airflow impact force shakes off the dust adhering to the surface of the filter element. The shaken-off dust will fall into the second collection frame 18 at the bottom of the second dust collection chamber 5 for discharge, thereby achieving efficient cleaning of the dust collection filter element 7, while reducing manual intervention and ensuring continuous and stable operation of the equipment.

[0029] Working principle: In actual use, the dust and smoke outlet of the dry quenching coke oven production process can be connected to the connecting pipe 2 at one end of the induced draft fan 1, and the induced draft fan 1 is started to allow the dust and smoke to enter the dust collection box 3. When the dust and smoke pass through the first dust collection chamber 4, the coarse dust particles in the dust and smoke will be intercepted by the coarse filter screen 6 and fall directly to the bottom, while the fine dust particles will enter the dust collection filter element 7 in the second dust collection chamber 5 and be captured by the dust collection filter element 7. A pulse tube 9 is installed directly above the dust collection filter element 7. The dust collection filter element 7 is periodically cleaned by the pulse dust collector 8 through the pulse tube 9 to prevent clogging. Finally, the clean gas after dust removal is discharged from the top of the dust collection box 3. This avoids the problem of manual ash removal during the dry quenching coke oven production process, which may cause harm to the operators.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
