Abstract
Description
Technical Field
[0001] This utility model belongs to the field of steel production technology, and in particular relates to a dust removal system with dual dust collectors. Background Technology
[0002] In the steel production process, belt conveyor systems are widely used in key processes such as coking, sintering, pelletizing, ironmaking, and steelmaking to achieve efficient and continuous material transport. While this conveying method greatly improves production efficiency, it also presents certain environmental challenges during operation. To effectively control dust pollution, each belt conveyor link is equipped with a dedicated dust collection system. These systems are connected to dust collectors via pipelines to collect and treat the dust generated during the conveying process, thereby ensuring a clean and environmentally friendly production environment.
[0003] However, in actual production, the dust collection duct design of some belt conveyor stations has certain limitations. For example, some transfer stations connect only a single dust collector to their dust collection points. While this design may seem sufficient for dust collection during normal operation, its shortcomings become apparent when the dust collector malfunctions and requires maintenance or shuts down for other reasons. Without backup dust collection equipment, the collection points cannot continue to effectively collect dust, leading to large-scale dust overflow and dust and smoke emissions. This not only seriously affects the air quality at the production site but may also trigger serious environmental accidents, causing significant economic losses and environmental pressure for enterprises, while also negatively impacting the surrounding ecological environment. Therefore, optimizing the configuration of dust collection systems and improving their reliability and stability to cope with emergencies such as dust collector failures has become a crucial issue that steel enterprises urgently need to address in their environmental management. Summary of the Invention
[0004] In view of the problems existing in the prior art, this utility model provides a dust removal system with dual dust collectors, which breaks through the traditional reliance on a single dust collector and effectively solves the risk of environmental accidents caused by the failure, maintenance or shutdown of a single dust collector. It can also flexibly adjust the connection status of different dust removal points.
[0005] This utility model is implemented as follows: a dust removal system with dual dust collectors includes a first dust collector and a second dust collector. The inlet ends of the first dust collector and the second dust collector are connected through a main pipe. A first dust removal pipe is connected to the main pipe near the first dust collector, and a second dust removal pipe is connected to the main pipe near the second dust collector. The dust removal end of the first dust removal pipe is connected to a first dust removal point, and the dust removal end of the second dust removal pipe is connected to a second dust removal point.
[0006] A first switching valve is installed on the main pipeline between the first dust removal pipeline and the first dust collector, a second switching valve is installed on the main pipeline between the first dust removal pipeline and the second dust removal pipeline, and a third switching valve is installed on the main pipeline between the second dust removal pipeline and the second dust collector.
[0007] Furthermore, the connecting end of the first dust removal pipe is provided with a first diversion pipe section and a second diversion pipe section. Both the first diversion pipe section and the second diversion pipe section are connected to the main pipe. The air outlet direction of the first diversion pipe section is towards the first dust collector, and the air outlet direction of the second diversion pipe section is towards the second dust collector. A first adjusting valve and a second adjusting valve are respectively provided on the first diversion pipe section and the second diversion pipe section.
[0008] Furthermore, the connecting end of the second dust collection duct is equipped with a third and a fourth diversion section, both of which are interconnected with the main duct. The outlet direction of the third diversion section faces the first dust collector, and the outlet direction of the fourth diversion section faces the second dust collector. A third and a fourth adjusting valve are respectively installed on the third and fourth diversion sections. This diversion and adjusting structure design allows the entire dust collection system to better adapt to changes in the needs of different operating conditions and dust collection points. Whether the dust generation at a dust collection point changes due to adjustments in the production process, or when a dust collector needs maintenance or repair, the airflow can be reasonably allocated by flexibly adjusting the adjusting valves, ensuring that other normally operating dust collectors can still efficiently handle the dust at the corresponding points. This fully utilizes the processing capacity of the two dust collectors, maintains the normal operation of the dust collection system, avoids dust and smoke problems caused by dust collector malfunctions, and improves the system's ability to respond to emergencies.
[0009] Furthermore, the first and second diversion pipe sections form a Y-shaped diversion structure with the first dust removal pipe.
[0010] Furthermore, the angle between the axis of the first dust removal pipe and the axis of the first diversion pipe section is 45°, and the angle between the axis of the first dust removal pipe and the axis of the second diversion pipe section is 45°.
[0011] Furthermore, the third and fourth diversion pipe sections form a Y-shaped diversion structure with the second dust removal pipe.
[0012] Furthermore, the angle between the axis of the second dust removal pipe and the axis of the third diversion pipe section is 45°, and the angle between the axis of the second dust removal pipe and the axis of the fourth diversion pipe section is 45°.
[0013] Furthermore, both the dust collection ends of the first and second dust collection pipes are conical structures, with the larger diameter end of the dust collection end facing the dust collection point. This allows for more efficient capture and collection of dust, reducing dust dispersion in the air, thereby improving dust collection efficiency, reducing dust pollution to the environment, and better meeting environmental protection requirements. The larger diameter end of the conical structure facing the dust collection point also more effectively captures and guides dust into the pipe, reducing dust dispersion at the pipe inlet and improving the collection efficiency of the dust collection system.
[0014] The advantages and technical effects of this utility model are as follows: By adopting the above-mentioned technical solution and utilizing the dual dust collector design, it breaks through the traditional reliance on a single dust collector, effectively solving the environmental accident risks caused by the failure, maintenance, or shutdown of a single dust collector. When a dust collector malfunctions, the corresponding dust collection point can be switched to another normally operating dust collector by operating the switching valve, ensuring continuous and effective dust collection at the dust collection point, maintaining a clean production environment, avoiding dust and smoke emissions caused by dust collection system failures, and ensuring the normal production order and environmental compliance of the enterprise. By setting multiple switching valves, the connection status of different dust collection points can be flexibly adjusted. The flexible switching method allows enterprises to rationally arrange the use and maintenance of dust collectors according to different production needs and equipment maintenance plans, improving the adaptability and operability of the entire dust collection system.

[0019] like Figure 1 As shown, this application provides a dust removal system with dual dust collectors, including a first dust collector 1 and a second dust collector 2. The inlet ends of the first dust collector 1 and the second dust collector 2 are connected by a main pipe 3. A first dust removal pipe 4 is connected to the main pipe 3 near the first dust collector 1, and a second dust removal pipe 5 is connected to the main pipe 3 near the second dust collector 2. The dust removal end of the first dust removal pipe 4 is connected to a first dust removal point, and the dust removal end of the second dust removal pipe 5 is connected to a second dust removal point. A first switching valve 6 is installed on the main pipe 3 between the first dust removal pipe 4 and the first dust collector 1. A second switching valve 7 is installed on the main pipe 3 between the first dust removal pipe 4 and the second dust removal pipe 5. A third switching valve 8 is installed on the main pipe 3 between the second dust removal pipe 5 and the second dust collector 2. The first switching valve 6, the second switching valve 7, and the third switching valve 8 are all butterfly valves.
[0020] Furthermore, the connecting end of the first dust removal pipe 4 is provided with a first diversion pipe section 9 and a second diversion pipe section 10. Both the first diversion pipe section 9 and the second diversion pipe section 10 are interconnected with the main pipe 3. The air outlet direction of the first diversion pipe section 9 is towards the first dust collector 1, and the air outlet direction of the second diversion pipe section 10 is towards the second dust collector 2. A first adjusting valve 11 and a second adjusting valve 12 are respectively provided on the first diversion pipe section 9 and the second diversion pipe section 10. The first adjusting valve 11 and the second adjusting valve 12 can be butterfly valves.
[0021] The connecting end of the second dust removal duct 5 is provided with a third diversion section 13 and a fourth diversion section 14, both of which are interconnected with the main duct 3. The air outlet direction of the third diversion section 13 is towards the first dust collector 1, and the air outlet direction of the fourth diversion section 14 is towards the second dust collector 2. A third adjusting valve 15 and a fourth adjusting valve 16 are respectively provided on the third diversion section 13 and the fourth diversion section 14. The third adjusting valve 15 and the fourth adjusting valve 16 can be butterfly valves.
[0022] The aforementioned diversion and adjustment structure design allows the entire dust collection system to better adapt to changing needs under different operating conditions and at different dust collection points. Whether the dust generation at a dust collection point changes due to adjustments in the production process, or when a dust collector needs maintenance or repair, the airflow can be rationally allocated by flexibly adjusting the various regulating valves, ensuring that other normally operating dust collectors can still efficiently handle the dust at the corresponding points. This fully utilizes the processing capacity of two dust collectors, maintains the normal operation of the dust collection system, avoids dust and smoke problems caused by dust collector malfunctions, and enhances the system's ability to respond to emergencies.
[0023] Furthermore, the first diversion pipe section 9 and the second diversion pipe section 10 form a Y-shaped diversion structure with the first dust removal pipe 4. Preferably, the angle between the axis of the first dust removal pipe 4 and the axis of the first diversion pipe section 9 is 45°, and the angle between the axis of the first dust removal pipe 4 and the axis of the second diversion pipe section 10 is 45°.
[0024] The third diversion pipe section 13 and the fourth diversion pipe section 14 form a Y-shaped diversion structure with the second dust removal pipe 5. Preferably, the angle between the axis of the second dust removal pipe 5 and the axis of the third diversion pipe section 13 is 45°, and the angle between the axis of the second dust removal pipe 5 and the axis of the fourth diversion pipe section 14 is 45°.
[0025] The aforementioned diversion structure design effectively reduces air resistance and energy loss during duct diversion. When air enters the diversion section from the dust collection duct, the 45° diversion angle allows for smoother airflow separation, avoiding airflow turbulence and eddy formation caused by excessively large or small angles. This not only improves the overall efficiency of the dust collection system but also ensures stable airflow at each dust collection point, reducing wind resistance and thus more effectively collecting dust, enhancing dust collection efficiency, and reducing dust pollution.
[0026] Furthermore, both the dust collection ends of the first dust collection pipe 4 and the second dust collection pipe 5 are conical structures, with the larger diameter end of the dust collection end facing the dust collection point. This allows for more efficient capture and collection of dust, reducing dust dispersion in the air, thereby improving dust collection efficiency, reducing dust pollution to the environment, and better meeting environmental protection requirements. The larger diameter end of the conical structure facing the dust collection point can more effectively capture and guide dust into the pipe, reducing dust dispersion at the pipe inlet and improving the collection efficiency of the dust collection system.
[0027] When the first dust collector 1 and the second dust collector 2 are operating normally, the first switching valve 6 and the third switching valve 8 are opened, and the second switching valve 7, the second adjusting valve 12 and the third adjusting valve 15 are closed, so that the first dust collector 1 collects dust at the first dust collection point and the second dust collector 2 collects dust at the second dust collection point, thereby improving the dust collection efficiency.
[0028] When the first dust collector 1 is under maintenance or shut down, close the first switching valve 6, open the second switching valve 7 and the third switching valve 8, close the first adjusting valve 11 and the third adjusting valve 15, and adjust the second adjusting valve 12 and the fourth adjusting valve 16 to a suitable air volume to avoid wasting air volume, so that the second dust collector 2 can collect dust from the first dust collection point and the second dust collection point.
[0029] When the second dust collector 2 is under maintenance or shut down, close the third switching valve 8, open the first switching valve 6 and the second switching valve 7, close the second adjusting valve 12 and the fourth adjusting valve 16, and adjust the first adjusting valve 11 and the third adjusting valve 15 to a suitable air volume to avoid wasting air volume, so as to realize the first dust collector 1 to collect dust from the first dust collection point and the second dust collection point.
[0030] By adopting the above technical solution and utilizing a dual-dust collector design, the traditional reliance on a single dust collector is overcome, effectively solving the environmental accident risks caused by the failure, maintenance, or shutdown of a single dust collector. When a dust collector malfunctions, the corresponding dust collection point can be switched to another normally operating dust collector by operating the switching valve, ensuring continuous and effective dust collection at the dust collection point, maintaining a clean production environment, and avoiding dust and smoke emissions caused by dust collection system failures. This safeguards the company's normal production order and environmental compliance. By setting multiple switching valves, the connection status of different dust collection points can be flexibly adjusted. This flexible switching method allows companies to rationally arrange the use and maintenance of dust collectors according to different production needs and equipment maintenance plans, improving the adaptability and operability of the entire dust collection system.
[0031] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
