Description

Technical Field

[0001] The invention relates to the technical field of waste gas dust removal and pollution control equipment, and in particular to a graphitization furnace waste gas desulfurization and dust removal device. Background Art

[0002] Graphite is an allotrope of carbon. It is a gray-black, opaque solid with stable chemical properties, corrosion resistance, and is not easy to react with acids, alkalis and other agents. It can be used as an anti-wear agent and lubricant. High-purity graphite is used as a neutron moderator in atomic reactors. It can also be used to make crucibles, electrodes, brushes, dry batteries, graphite fibers, heat exchangers, coolers, arc furnaces, arc lamps, pencil refills, etc.

[0003] In the graphite production process, the most important thing is the graphitization furnace.

[0004] In the process of graphitizing carbon materials, sulfides and some dust will be produced. Sulfides and dust cannot be discharged directly into the atmosphere and need to be treated. However, in the dust removal process, solid particles are easy to clog the filter and are not easy to clean, resulting in a decrease in the filtering effect and affecting the exhaust gas treatment efficiency. When the filter and desulfurizer need to be replaced, the entire system needs to be shut down, which reduces the exhaust gas treatment efficiency.

[0071] Specifically, sealing strips are installed around the second opening 12, and sealing strips are also installed on the bottom and both sides of the second closing plate 142 to prevent exhaust gas from escaping from the second opening 12 and polluting the environment; the second closing plate 142 is a right-angled trapezoidal structure, and the inclined surface faces the outside of the desulfurization box 2, which is convenient for the storage drawer 131 to push the second closing plate 142 open; the second guide rod 144 corresponds to the second guide groove 143 one by one, and the second guide rod 144 and the second guide groove 143 are slidably matched; after the storage drawer 131 is pulled out, the second guide rod 144 is opened in the third guide groove 143; Under the elastic force of the spring 145, the second closing plate 142 is pushed downward, so that the second closing plate 142 automatically closes the second opening 12; when the storage drawer 131 is put back, the storage drawer 131 pushes the second closing plate 142 upward into the second movable groove 141 through the inclined surface of the second closing plate 142, and the storage drawer 131 is placed back into the desulfurization box 2 through the second opening 12. Because of the resistance of the storage drawer 131, the second closing plate 142 is sealed and abutted against the top of the storage drawer 131.

[0072] Reference Figure 2 In this embodiment, controllers are installed on both the dust removal box 1 and the desulfurization box 2. The controller on the dust removal box 1 is electrically connected to the first motor 64, the third motor 101 and the gas sensor in the dust removal box 1; the controller on the desulfurization box 2 is electrically connected to the second motor 114, the first duct fan 42, the second duct fan 17 and the gas sensor in the desulfurization box 2.

[0073] In this embodiment, the first motor 64, the second motor 114, the third motor 101, the first duct fan 42, the second duct fan 17 and the gas sensor are all existing devices and will not be described in detail herein.

[0074] Working principle: When in use, the exhaust gas enters the dust removal box 1 through the air intake pipe 3 after being cooled. At this time, the first baffle 63 and the second baffle 113 are both in the open state. The first duct fan 42 and the second duct fan 17 are started to increase the speed of exhaust gas transportation. The exhaust gas first passes through the filter 86 to filter the dust in the exhaust gas. At the same time, the third motor 101 is started, the third motor 101 drives the fifth shaft 102 to rotate, the fifth shaft 102 drives the active synchronous pulley 103 to rotate, the active synchronous pulley 103 drives the driven synchronous pulley 105 to rotate through the synchronous belt 106, and the driven synchronous pulley 105 drives the sixth shaft 104 to rotate, so that The cams 107 on the fifth rotating shaft 102 and the sixth rotating shaft 104 rotate synchronously to knock the filter 86. Under the elastic action of the first spring 85, the filter 86 vibrates back and forth to prevent the filter 86 from being blocked by solid particles, and the dust attached to the filter 86 is shaken off. The dust falls into the dust collecting drawer 20, which is convenient for centralized cleaning. The exhaust gas passes through the filter 86 through the outlet pipe 41 and the air supply pipe 43, and is sprayed into the desulfurization box 2 through the nozzle 16. It contacts the desulfurizer 132 through the small hole 133 in the storage drawer 131, absorbs the sulfide in the exhaust gas, and then the purified gas is discharged through the exhaust pipe 5.

[0075] When the filter 86 needs to be replaced or cleaned, the first motor 64 is started, the first motor 64 drives the first shaft 61 to rotate, the first shaft 61 drives the first driving gear 65 to rotate, and the first driving gear 65 drives the first rack 68 to move, thereby driving the first driven gear 66 to rotate, and the first driven gear 66 drives the second shaft 62 to rotate. At the same time, the first shaft 61 and the second shaft 62 drive the first baffle plate 63 to rotate, so that the first baffle plate 63 blocks the exhaust gas entering the dust removal box 1, wait for a period of time, and after the exhaust gas above the first baffle plate 63 is discharged from the dust removal box 1 under the conveyance of the first duct fan 42, the filter assembly 8 is pulled out, and under the elastic force of the second spring 95, the first closing plate 92 is pushed downward, so that the first closing plate 92 automatically closes the first opening 7, and the first motor 64 is restarted to open the first baffle plate 63;

[0076] When it is necessary to put the filter assembly 8 back into the dust removal box 1, start the first motor 64 so that the first baffle plate 63 blocks the exhaust gas entering the dust removal box 1. After waiting for a while, the exhaust gas above the first baffle plate 63 is discharged from the dust removal box 1 under the transportation of the first duct fan 42. Then, first, pull the lifting block 96 to push the first closing plate 92 upward into the first moving groove 91 to open the first opening 7, and then put the filter assembly 8 back into the dust removal box 1 through the first opening 7. Then, release the lifting block 96, restart the first motor 64, and open the first baffle plate 63.

[0077] When the desulfurizing agent 132 needs to be replaced, the second motor 114 is started, the second motor 114 drives the third rotating shaft 111 to rotate, the third rotating shaft 111 drives the second driving gear 115 to rotate, the second driving gear 115 drives the second rack 118 to move, thereby driving the second driven gear 116 to rotate, the second driven gear 116 drives the fourth rotating shaft 112 to rotate, and at the same time, the third rotating shaft 111 and the fourth rotating shaft 112 drive the second shielding plate 113 to rotate, so that the second shielding plate 113 is opposite to the desulfurizing agent 132. The exhaust gas in the desulfurization box 2 is isolated, and at the same time, the first pipeline fan 42 is turned off. After waiting for a period of time, the exhaust gas above the second baffle plate 113 is discharged from the desulfurization box 2 under the transportation of the second pipeline fan 42, and the storage drawer 131 is pulled out. Under the elastic force of the third spring 145, the second closing plate 142 is pushed downward, so that the second closing plate 142 automatically closes the second opening 12, and the second motor 114 is restarted to open the second baffle plate 113. At the same time, the first pipeline fan 42 is restarted;

[0078] When it is necessary to put the storage drawer 131 back into the desulfurization box 2, start the second motor 114 so that the second baffle 113 blocks the exhaust gas entering the desulfurization box 2. At the same time, turn off the first duct fan 42, wait for a while, and after the exhaust gas above the second baffle 113 is discharged from the desulfurization box 2 under the transportation of the second duct fan 42, the storage drawer 131 pushes the second closing plate 142 upward into the second movable groove 141 through the inclined surface of the second closing plate 142, and the storage drawer 131 is placed back into the desulfurization box 2 through the second opening 12. The second motor 114 is restarted to open the second baffle 113. At the same time, the first duct fan 42 is restarted.
