Description

Technical Field

[0001] The utility model relates to the field of fluidized bed design, in particular to a double-bag dust removal combined exhaust system. Background Art

[0002] A fluidized bed is a chemical reactor whose main forces are inertia, buoyancy, and resistance. It utilizes the suspension effect of gases or liquids between solid particles to suspend the solid particles in the airflow, forming a "fluidized bed."

[0003] When the fluidized bed is in use, the reaction of materials and the combustion of fuel in the power unit may generate a certain amount of waste gas. In order to prevent the waste gas from remaining in the fluidized bed, an exhaust system is usually installed on the fluidized bed to discharge the waste gas.

[0004] However, since the fluidized bed is mainly used for processing particulate materials, when the existing exhaust system is working, some particulate materials are easily discharged to the outside along with the flow of exhaust gas, which causes waste of materials and easily pollutes the external environment. In addition, the particulate materials are also easy to adhere to the components or pipes of the exhaust system, causing blockage of the exhaust system and affecting the exhaust of the exhaust system.

The air outlet 52 is provided at the top of the cyclone separator 5, the discharge port 53 is provided at the bottom of the cyclone separator 5, and the air inlet 51 is provided at the side of the cyclone separator 5.

[0025] The double-bag dust removal combined exhaust system also includes a first air pipe 7. One end of the first air pipe 7 is fixedly connected to the air inlet 51 by bolts, and this end of the first air pipe 7 is connected to the air inlet 51. The other end of the first air pipe 7 is connected to the exhaust port of the fluidized bed 4, and this end of the first air pipe 7 is connected to the exhaust port of the fluidized bed 4. In this way, the fluidized bed 4 and the air inlet of the cyclone separation device 5 are connected and communicated.

[0026] The processing cabinet 1 is provided with an air inlet 11 and an air outlet 12. The first bag dust collector 2 and the second bag dust collector 3 are respectively connected to the processing cabinet 1 by bolts, and the first bag dust collector 2 and the second bag dust collector 3 are arranged side by side. Therefore, the airflow entering through the air inlet 11 can flow into the first bag dust collector 2 and the second bag dust collector 3 respectively, and the airflow flowing out of the first bag dust collector 2 and the second bag dust collector 3 can both flow out through the air outlet 12.

[0027] The double-bag dust removal combined exhaust system also includes a second air pipe 8. One end of the second air pipe 8 is fixedly connected to the exhaust port 52 by a bolt, and the second end of the second air pipe 8 is connected to the air inlet 11, and the second end of the second air pipe 8 is connected to the air inlet 11. In this way, the air inlet of the processing cabinet 1 and the exhaust port 52 of the cyclone separation device 5 are connected and communicated.

[0028] The double-bag dust removal combined exhaust system further includes a first valve 9 , which is fixedly mounted on the discharge port 53 by means of bolts. The first valve 9 is configured to be able to open and close the discharge port 53 .

[0029] The double-bag dust removal combined exhaust system also includes a third air pipe 10. One end of the third air pipe 10 is fixedly connected to the air outlet 12 by bolts, and the other end of the third air pipe 10 is connected to the air intake of the fan 6, and the other end of the third air pipe 10 is connected to the air intake of the fan 6.

The exhaust gas in the processing cabinet 1 can enter the first bag dust removal device 2 or the second bag dust removal device 3, so that the particulate matter remaining in the exhaust gas can be further removed by the first bag dust removal device 2 or the second bag dust removal device 3 and collected in the first bag dust removal device 2 or the second bag dust removal device 3, and the exhaust gas is basically converted into conventional gas. In the present invention, the two bag dust removal devices are arranged in parallel, and the two bag dust removal devices share an air inlet 11 and an air outlet 12, which can directly increase the filtering area of ​​the exhaust gas during the exhaust process and effectively reduce the risk of bag clogging.

[0034] The gas treated by the first bag filter 2 or the second bag filter 3 can be delivered to the fan 6 through the third air pipe 10. The fan 6 can then deliver the treated gas to the outside or to subsequent processing equipment. Alternatively, by opening the second valve 30, the fan 6 can re-deliver the treated gas to the fluidized bed 4 for reuse, thereby facilitating the reuse of heat in the gas.
