Description

Technical Field

[0001] This utility model relates to the field of dust-containing gas collection and treatment, and in particular to an ultrafine dust collection device with a ceramic filter membrane. Background Technology

[0002] With the continuous development of industrial production, the impact of ultrafine dust is becoming increasingly significant. On the one hand, ultrafine dust is a pollutant in some industrial processes, posing a significant threat to human health. On the other hand, some ultrafine dust can also be used as high-value production materials in fields such as chemical, petroleum, biological, and metallurgical industries. Therefore, the precision and efficiency of ultrafine dust collection are constantly being improved. Ultrafine dust collection devices are a type of dust collector specifically designed for collecting ultrafine dust. They can serve as purification devices for industrial dust pollution gases and as collection devices for industrial processes utilizing ultrafine dust, and are widely used in chemical, petroleum, biological, and metallurgical fields.

[0003] The ultrafine dust collection device mainly consists of a housing, filter cartridges, a support device, and a dust collector. The housing serves as the main outer shell to protect the internal structure and provide a sealed space. Inside, the filter cartridges are fixed in position by the support device. Gas flows into the working chamber where the filter cartridges are located, and after filtration, it is discharged from the outlet. At the same time, the filtered dust enters the dust collector. After the gas supply stops, the dust removal device separates the ultrafine dust adhering to the surface of the filter cartridges and collects it by the dust collector, thus completing the collection of ultrafine dust.

[0004] In the existing technology, some ultrafine dust collection devices use a single filter cartridge, and the filter chamber connection takes up a lot of space. Multiple filter cartridges cannot be accommodated in the same volume working chamber. Moreover, the collected ultrafine dust cannot be separated separately, but is mixed with other impurities. Collecting it separately requires more auxiliary equipment, resulting in low collection efficiency. Therefore, an ultrafine dust collection device with a ceramic filter membrane is proposed to solve the above problems. Utility Model Content

[0033] 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.

[0034] Reference Figures 1 to 3This utility model provides an embodiment of an ultrafine dust collection device with a ceramic filter membrane, comprising a working chamber 1, which provides a stable working space and protects the internal structure. A connecting pipe a4 is fixedly connected to the top left side of the working chamber 1 for connection to a fan a25. A connecting pipe b14 is fixedly connected to the bottom right side of the working chamber 1 for connection to a residual gas treatment chamber 15. A working chamber inlet pipe 5 is detachably connected to the right side of the connecting pipe a4, forming an upper-side sealed working chamber with a filter tube fixing plate 6 and supplying gas into the working chamber. A filter tube fixing plate 6 is slidably connected to the bottom outer side of the working chamber inlet pipe 5, fixing the position of the ceramic membrane filter tube and forming the working chamber. A ceramic membrane filter tube 8 is fixedly connected inside the filter tube fixing plate 6, adsorbing only ultrafine dust within a specific size range. A bracket a7 is fixedly connected to the top of the filter tube fixing plate 6 for easy disassembly when replacing the filter tube. A mesh support plate 9 is fixedly connected to the inner side of the working chamber 1 to support the filter tube fixing plate. 6. The airflow in the working chamber is uniformly passed through the ceramic membrane filter tube 8. The bottom outer side of the filter tube fixing plate 6 is detachably connected to the top of the mesh support plate 9. The bottom of the working chamber 1 is provided with a collection component, which includes a collection chamber 10, which is used to collect ultrafine dust. The top of the collection chamber 10 is fixedly connected to the bottom of the working chamber 1. The lower side of the inside of the collection chamber 10 is slidably connected to a slider 13, which is used to allow the collector 11 to move along the slider 13. The top of the slider 13 is fixedly connected to the collector 11, which is used to collect, store and remove ultrafine dust. The bottom of the collector 11 is fixedly connected to a sensor a12, which is used to detect the quality of ultrafine dust. The bottom of the collection chamber 10 is fixedly connected to a circuit box 33, which is used to protect the main circuit of the entire machine. The middle of the front and rear sides of the working chamber 1 is fixedly connected to a bracket b24, which is used to fix the working chamber 1. The bottom of the bracket b24 is fixedly connected to the top of the circuit box 33. The top of the circuit box 33 is fixedly connected to a support frame 31, which is used to support the fan b27.

[0035] A power assembly is located on the left side of the working chamber 1. This assembly includes blower a25 and blower b27. Blower b27 is internally and fixedly connected to the outside of connecting pipe a4. An air inlet a28 is fixedly connected to the left side of blower b27 to allow the gas to be treated to enter. An air inlet b30 is fixedly connected to the left side of blower a25 to allow clean gas to enter. A support column 26 is fixedly connected to the top of blower a25 to ensure stable operation. Blower a25 starts working, allowing gas containing ultrafine dust to enter the device, pass through the working chamber, and finally exit from outlet 22. Blower b27 starts working after blower a25 stops, using pure airflow to blow off the ultrafine dust adhering to the surface of the ceramic membrane filter tube 8, causing it to fall into the collection assembly, thus completing the collection of ultrafine dust.

[0036] Reference Figures 4 to 6A residual gas treatment chamber 15 is fixedly connected to the right side of the connecting pipe b14. Its function is to treat residual gas. A filter layer a18, a filter layer b19, a filter layer c20, and a filter layer d21 are slidably connected to the inner wall of the residual gas treatment chamber 15. Support bearings 16 are fixedly connected to both sides of the filter layer a18. Their function is to connect and fix the four filter layers for easy installation and disassembly. A sensor b17 is fixedly connected to the top right side of the inner wall of the residual gas treatment chamber 15. Its function is to detect the content of filter material on the filter layer and remind the staff to replace the filter layer in time. After the residual gas enters the residual gas treatment chamber 15, it passes through filter layer a18, filter layer b19, filter layer c20, and filter layer d21 sequentially from top to bottom under the action of the power source, and is finally discharged through the outlet 22. This process ensures that harmful substances in the residual gas are retained on the four filter layers, achieving the effect of separating ultrafine dust and other impurities and purifying the collected gas. The top of the residual gas treatment chamber 15 is threadedly connected to a top cover b23 to achieve a sealed effect. The outlet 22 is fixedly connected to the bottom right side of the residual gas treatment chamber 15. The bottom of the residual gas treatment chamber 15 is fixedly connected to a rectangular support plate 32 to support the residual gas treatment chamber 15. The top of the working chamber 1 is threadedly connected to a top cover a2 for the working chamber 1. The top cover a2 is threadedly connected around its perimeter to a reinforcing screw 3 for the working chamber 1 and the top cover a2. The bottom of the reinforcing screw 3 is threadedly connected to the top of the working chamber 1. The right outer perimeter of the connecting pipe a4 is fixedly connected to a pipe connector 29 for connecting different pipes. The outside of the pipe connector 29 is fixedly connected to the left side of the blower b27.

[0037] Working principle: When the fan is started, the gas to be treated enters through the inlet a28 and flows into the working chamber 1 through the connecting pipe a4. It then enters the working chamber through the working chamber inlet pipe 5. The top of the working chamber is sealed by the filter tube fixing plate 6 to prevent gas from overflowing. The ceramic membrane filter tube 8 runs through the bottom of the working chamber and is evenly distributed through the holes of the mesh support plate 9, so that the gas flows from top to bottom through the ceramic membrane filter tube 8, filtering out the ultrafine dust and leaving it on the surface of the membrane tube. Under the action of the power source, the remaining gas enters the remaining gas treatment chamber 15 through the connecting pipe b14. As the ultrafine dust accumulates, some of the dust falls into the collection chamber 10 due to gravity and is received by the collector 11.

[0038] When fan a25 stops working, fan b27 starts, delivering clean gas to the bottom of the working chamber through the cleaning fan inlet b30, blowing off the remaining dust on the ceramic membrane filter tube 8 and guiding it into the collection chamber 10. Sensor a12 monitors the weight of the dust, and when the set standard is reached, fan b27 stops. The collector 11 can be pulled out by slider 13, making it easy to remove the collected dust. This increases the number of ceramic membrane filter tubes 8 and optimizes the efficiency of gas flow and dust collection, thereby effectively saving space and improving processing capacity.

[0039] When the equipment is working, the residual gas enters the residual gas treatment chamber 15 through the connecting pipe b14 via the fan a25. In the residual gas treatment chamber 15, the gas passes through the filter layer a18, filter layer b19, filter layer c20 and filter layer d21 from top to bottom, so that the harmful substances in the residual gas are filtered out. Finally, the gas is discharged through the outlet 22. The sensor b17 can detect the accumulation of filter material on the four filter layers. When filtration can no longer continue, it can send a signal to remind the filter layer to be replaced. The residual gas treatment chamber 15 can collect ultrafine dust and separate ultrafine dust from other harmful substances at the same time, so as to reduce pollution and prevent ultrafine dust from mixing with other substances.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
