Description

Technical Field

[0001] The invention relates to the technical field of bag dust collectors, and in particular to a bag dust collector cooling device for high-temperature airflow dust removal. Background Art

[0002] Bag dust collector is a common environmental protection equipment that separates and filters dust-containing gas through bags. When used in the field of metallurgical production, a large amount of high-temperature gas containing smoke and dust will be generated during the processing and production process. When the high-temperature gas is treated for environmental protection, the high-temperature gas needs to be cooled first to avoid the high-temperature gas from reducing the service life of the filter bag or directly damaging it.

[0003] The utility model with the existing publication number CN215692469U discloses a bag dust collector with a cooling structure. The cooling mechanism is provided to spray water through a spray head to cool the inside of the dust box to avoid the situation where the bag inside the main mechanism is damaged by high temperature due to excessive temperature. The dust blowing mechanism is provided to blow air through the filter device through the air duct so that the dust inside the filter enters the bottom of the main mechanism for storage. At the same time, the dust collector filter element slides from the upper end of the slot into the inside of the slot through a card block to fix it, thereby increasing its stability. When the above scheme is used, a spray water mechanism is added to the air inlet duct of the bag dust collector to cool the incoming airflow. Although this method has an effective cooling effect, when it is used, as the high-temperature evaporation of water body occurs, it is easy to cause the inside of the bag dust collector to be relatively humid, which may cause "bag sticking" and other effects on the use of separation and filtration. The method of adding an independent heat exchanger externally to cool the hot air flow is limited by the state of use of the equipment. When the hot air flow enters the bag dust collector, a high stability phenomenon may still occur, which has certain hidden dangers. Summary of the invention

DETAILED DESCRIPTION

[0039] Please refer to the attached Figure 1-16 , this application provides the following technical solutions.

[0040] Embodiment 1: A bag filter cooling device for high-temperature airflow dust removal, comprising:

[0041] The bag dust collector box 1 is vertically arranged through the support frame, the lower end of the bag dust collector box 1 is provided with a collecting bin 5, the upper ends of both sides of the bag dust collector box 1 are respectively connected with an access air connector 2 and a discharge pipe 3, an air bag 4 is horizontally installed on one side of the bag dust collector box 1, a cooling treatment box 6 is vertically arranged on one side of the bag dust collector box 1 near the access air connector 2, a bag installation plate 7 is horizontally arranged on the upper end of the bag dust collector box 1, one side of the bag installation plate 7 is connected to the cooling treatment box 6, and the cooling treatment box 6 is near the access air connector 2. A through hole is opened on one side of the gas joint 2, and a cooling contact seat 9 is vertically arranged on one side of the through hole in the cooling treatment box 6, and the inner peripheral diameter of the cooling contact seat 9 is the same as the diameter of the through hole. When in use, the high-temperature airflow containing smoke and dust enters the cooling treatment box 6 through the gas joint 2, and then flows from the bottom of the cooling treatment box 6 to the bottom of the bag mounting plate 7. A plurality of filter bags are installed on the bag mounting plate 7. The airflow is filtered after being cooled by the filter bags. When the bag is blocked, a high-pressure airflow is blown to the bag through the air bag 4 to perform self-cleaning of the bag.

[0042] A flow guide and cooling component is provided to directly cool the airflow entering the cooling treatment box 6. The flow guide and cooling component is provided on the side of the cooling treatment box 6 close to the access air joint 2. The flow guide and cooling component includes a cooling contact seat 9 and a flow guide cover 11. A control seat 8 is provided on the side of the cooling treatment box 6 away from the access air joint 2. The lower end of the control seat 8 is higher than the upper end of the bag mounting plate 7. A control shaft 10 is horizontally provided at the center of one side of the flow guide cover 11. The control shaft 10 is rotatably plugged into the control seat 8 through a bearing. A cooling diffusion groove 13 and an arc-shaped flow guide groove 12 are respectively provided on the opposite sides of the cooling contact seat 9 and the flow guide cover 11, and the outer edge diameter of the arc-shaped flow guide groove 12 is smaller than the outer edge diameter of the cooling diffusion groove 13. The cooling contact seat 9 is provided with a cooling diffusion groove 13 and an arc-shaped flow guide groove 12. The outer edge diameter of the arc-shaped flow guide groove 12 is smaller than the outer edge diameter of the cooling diffusion groove 13. A first cooling chamber 19 is provided. When the hot air flow enters the cooling treatment box 6, cooling air is continuously supplied into the first cooling chamber 19. At this time, the air temperature on the inner peripheral side of the annular cooling contact seat 9 is reduced, and the hot air flow is initially cooled when passing through. Then, after contacting the air guide cover 11, it returns to the cooling diffusion groove 13 under the guiding effect of the arc-shaped guide groove 12. Since the cooling diffusion groove 13 is located at the first cooling chamber 19 and also has a relatively cold contact surface, the airflow that has undergone initial cooling is further cooled at this time. Then, under the guiding effect of the cooling diffusion groove 13, the airflow diffuses to the four sides. During the diffusion process, the disturbance between the airflows causes the airflows to mix and turbulent, thereby enhancing the cooling effect.

[0043] In addition, under the turbulence effect after the airflow contacts the guide cover 11 and the cooling contact seat 9, the smoke particles in the airflow collide with each other, and the larger particles or the re-aggregated particles fall directly downward.

[0044] An enhanced cooling component is set to further cool the hot air flow. The enhanced cooling component is horizontally arranged below the cooling contact seat 9 and the guide cover 11 in the cooling treatment box 6.

A plurality of second cooling chambers 29 are opened in the enhanced cooling plate 27 horizontally through the two circulating cold boxes 31 respectively, and a flow slot 28 is opened horizontally between the two adjacent second cooling chambers 29 in the enhanced cooling plate 27. The centers of the two sides of the flow slot 28 are respectively penetrated and connected with two circulating cold boxes. The box 31 is provided with a sealed pipe groove, and the cooling pipe 30 is horizontally placed in the flow groove 28 and inserted into the two sealed pipe grooves, and the upper and lower ends of the flow groove 28 are respectively penetrated through the enhanced cooling plate 27 to provide a conical guide surface. When the airflow containing a certain amount of heat is cooled by the cooling contact seat 9 and flows downward, it flows to the lower part of the bag dust collector box body 1 through the flow groove 28 of the enhanced cooling plate 27. When passing through the flow groove 28, the cooling pipe 30 and the second cooling chamber 29 are sent into the circulating refrigeration airflow through the two circulating cold boxes 31. At this time, the airflow passing through the flow groove 28 contacts the cooling pipe 30 and the side wall of the flow groove 28, and is enhanced and cooled by the side wall of the flow groove 28 and the side wall of the cooling pipe 30 with a relatively cold surface, so that the temperature of the airflow contacting the filter bag in the later stage is appropriate or not affected by the use state of the external independent heat exchanger, and can be subjected to its own enhanced cooling treatment when the airflow enters the bag dust collector box body 1;

[0045] In addition, the number of enhanced cooling plates 27 can be designed as needed according to the operating environment or the operating temperature range of the externally installed heat exchanger.
