Abstract
Description
Technical Field
[0001] The utility model relates to the field of carbonization furnace filtering equipment, in particular to a tar and dust filtering mechanism and a filtering system for a graphite membrane. Background Art
[0002] Polyimide film is the best performing thin-film insulating material in the world. It is made by polycondensing pyromellitic dianhydride (PMDA) and diaminodiphenyl ether (ODA) in a strong polar solvent, casting into a film, and then imidizing.
[0003] During the carbonization process, the PI membrane will be preheated, and acidic gases, tar and other impurities will be discharged during this process. The amount of tar discharged in this process is particularly large, which will affect the service life of the pump and the stability of the product. Therefore, it is particularly critical whether the filtration system can filter the maximum amount of tar.
[0004] There are some carbonization furnace filtering equipment on the market, but they cannot filter tar well, and the tar is easily accumulated at the last pump, causing damage to the pump. Utility Model Content
[0005] The utility model aims at the above-mentioned problems, overcomes at least one disadvantage, and proposes a tar and dust filtering mechanism and a filtering system for a graphite membrane.
[0006] The technical solution adopted by the utility model is as follows:
[0007] A tar and dust filtering mechanism, comprising:
[0008] Filter box, used to contain liquid tar and dust adsorption media;
[0009] an air inlet pipe, arranged on the filter box, wherein a first end of the air inlet pipe is used to receive the gas to be filtered, and a second end of the air inlet pipe is used to guide the gas to be filtered to the upper surface of the tar and dust adsorption medium in the filter box, wherein the tar and dust adsorption medium is used to dissolve the tar and dust in the gas to be filtered and to precipitate the tar and dust;
[0010] The gas outlet pipe is connected to the inner space of the filter box and is located above the tar and dust adsorption medium, and is used for allowing the gas adsorbed by the tar and dust adsorption medium to pass through.
[0011] In actual use, the liquid tar and dust adsorption medium is a material such as engine oil. For example, in the case of engine oil, it can be 100# engine oil.
[0012] The present application enables the gas to be filtered to move toward the upper surface of the tar and dust adsorption medium through the second end of the air inlet pipe. The tar and dust adsorption medium can quickly adsorb the tar and dust and precipitate the tar and dust, and then the filtered gas is discharged from the filter box through the outlet pipe.
[0013] In one embodiment of the utility model, the second end of the air inlet pipe has a guide plate, the lower surface of the guide plate faces the upper surface of the tar and dust adsorption medium, and the guide plate is used to make the gas to be filtered contact more with the surface of the tar and dust adsorption medium.
[0014] When the guide plate is not set, the contact surface between the gas to be filtered and the tar and dust adsorption medium is small, and the filtration is not clean. By setting the guide plate, the gas can have more contact with the surface of the tar and dust adsorption medium when flowing, effectively improving the filtration effect.
[0015] In one embodiment of the present invention, the periphery of the guide plate is gap-matched with the inner wall of the filter box.
[0016] This arrangement enables the maximum amount of gas to be filtered to contact the tar and dust adsorption medium and be precipitated and filtered, and also ensures reliable flow of the gas path through the circumferential gap.
[0017] In one embodiment of the utility model, an overflow pipe and a liquid level container are further included, wherein a first end of the overflow pipe is communicated with the inner space of the filter box, and a second end of the overflow pipe is communicated with the liquid level container;
[0018] The first end of the overflow pipe is adjacent to the guide plate, and the lowest point of the first end of the overflow pipe is located below the guide plate.
[0019] With this arrangement, when there are a lot of impurities, the liquid level of the tar and dust adsorption medium can flow into the liquid level container through the overflow pipe after moving up.
[0020] In one embodiment of the utility model, the overflow pipe is a three-way pipe, and the overflow pipe also has a third end. A first control valve is provided between the second end of the overflow pipe and the liquid level container; the third end of the overflow pipe is used to replenish the tar and dust adsorption medium into the internal space of the filter box.
[0021] When there is no need to replenish the tar and dust adsorption medium, the third end of the overflow pipe is blocked and the first control valve is opened. When there is a need to replenish the tar and dust adsorption medium, the first control valve is closed and the third end of the overflow pipe is used to replenish the tar and dust adsorption medium into the internal space of the filter box.
[0022] In one embodiment of the present invention, a side wall of the filter box has a liquid level window, and the liquid level window corresponds to the area where the second end of the air inlet pipe is located.
[0023] The liquid level of tar and dust adsorption medium can be observed through the liquid level window, which is convenient for controlling the liquid level to ensure the reliability of filtration.
[0024] In one embodiment of the present invention, the side wall of the second filter box also has an impurity viewing window, which is located between the bottom of the internal space of the filter box and the liquid level viewing window, and is closer to the bottom of the internal space of the filter box; the filter box also has a waste pipe, on which a second control valve is installed, and the waste pipe is connected to the bottom of the internal space of the filter box.
[0025] The amount of adsorbed impurities can be observed through the liquid level window. When the amount of impurities is large, the impurities can be discharged by opening the second control valve.
[0026] In one embodiment of the present invention, the liquid level window and the impurity window both include a transparent plate sealedly mounted on the side wall of the filter box and a riot-proof blind plate detachably mounted on the outside of the transparent plate.
[0027] The transparent plate can be glass, and the design of the anti-explosion blind plate can ensure that the use of the device is not affected even if the transparent plate is broken.
[0028] The present application also discloses a filtering system for graphite membrane, comprising the tar and dust filtering mechanism described above.
[0029] The beneficial effect of the utility model is that the present application can make the gas to be filtered move toward the upper surface of the tar and dust adsorption medium through the second end of the air inlet pipe first, and through the tar and dust adsorption medium, the tar and dust can be quickly adsorbed and precipitated, and then the filtered gas is discharged from the filter box through the outlet pipe.

[0040] The utility model is described in detail below in conjunction with the accompanying drawings.
[0041] like Figure 1 , 2 As shown in 3, a tar and dust filtering mechanism comprises:
[0042] A filter box 1 for containing liquid tar and dust adsorption medium 2;
[0043] An air inlet pipe 3 is provided on the filter box 1. A first end 3a of the air inlet pipe is used to receive the gas to be filtered. A second end 3b of the air inlet pipe is used to guide the gas to be filtered to the upper surface of the tar and dust adsorption medium 2 in the filter box 1. The tar and dust adsorption medium 2 is used to dissolve the tar and dust in the gas to be filtered and to precipitate the tar and dust.
[0044] The gas outlet pipe 4 is connected to the inner space of the filter box 1 and is located above the tar and dust adsorption medium 2 for allowing the gas adsorbed by the tar and dust adsorption medium 2 to pass through.
[0045] In actual use, the liquid tar and dust adsorption medium 2 is a material such as engine oil, for example, it can be 100# engine oil. When in use, the air outlet pipe 4 can be directly or indirectly connected to the suction pump, so that the gas to be filtered can enter through the air inlet pipe 3 and finally be discharged through the air outlet pipe 4. The present application enables the gas to be filtered to move toward the upper surface of the tar and dust adsorption medium 2 through the second end 3b of the air inlet pipe, and through the tar and dust adsorption medium 2, the tar and dust can be quickly adsorbed and precipitated, and then the filtered gas is discharged from the filter box 1 through the air outlet pipe 4.
[0046] like Figure 3 and 4 As shown, in this embodiment, the second end 3b of the air inlet pipe has a guide plate 31, the lower surface of the guide plate 31 is opposite to the upper surface of the tar and dust adsorption medium 2, and the guide plate 31 is used to make the gas to be filtered contact more with the surface of the tar and dust adsorption medium 2.
[0047] When the guide plate 31 is not provided, the contact surface between the gas to be filtered and the tar and dust adsorption medium 2 is small, and the filtration is not clean. By providing the guide plate 31, the gas can have more contact with the surface of the tar and dust adsorption medium 2 when flowing, effectively improving the filtering effect.
[0048] like Figure 3 As shown, in this embodiment, the circumference of the guide plate 31 is matched with the inner wall gap of the filter box 1. This arrangement can make the gas to be filtered contact the tar and dust adsorption medium 2 in the largest amount and be precipitated and filtered, and the circumferential gap also ensures the reliable flow of the gas path.
[0049] like Figure 2 and 4 As shown, in this embodiment, an overflow pipe 5 and a liquid level container 6 are also included, the first end 5a of the overflow pipe is connected to the internal space of the filter box 1, and the second end 5b of the overflow pipe is connected to the liquid level container 6;
[0050] The first end 5 a of the overflow pipe is adjacent to the guide plate 31 , and the lowest point of the first end 5 a of the overflow pipe is located below the guide plate 31 .
[0051] With such arrangement, when there are a lot of impurities, the liquid level of the tar and dust adsorption medium 2 can flow into the liquid level container 6 through the overflow pipe 5 after moving upward.
[0052] like Figure 1 and 4 As shown, in this embodiment, the overflow pipe 5 is a three-way pipe, and the overflow pipe 5 also has a third end. A first control valve 51 is provided between the second end 5b of the overflow pipe and the liquid level container 6; the third end 5c of the overflow pipe is used to replenish the tar and dust adsorption medium 2 into the internal space of the filter box 1.
[0053] When there is no need to replenish the tar and dust adsorption medium 2, the third end 5c of the overflow pipe is blocked and the first control valve 51 is opened. When it is necessary to replenish the tar and dust adsorption medium 2, the first control valve 51 is closed and the third end 5c of the overflow pipe is used to replenish the tar and dust adsorption medium 2 to the internal space of the filter box 1.
[0054] like Figure 5 As shown, in this embodiment, the side wall of the filter box 1 has a liquid level window 1a, and the liquid level window 1a corresponds to the area where the second end 3b of the air intake pipe is located. The liquid level of the tar and dust adsorption medium 2 can be observed through the liquid level window 1a, which is convenient for controlling the liquid level to ensure the reliability of filtration.
[0055] like Figure 3 and 5 As shown, in this embodiment, the side wall of the second filter box also has an impurity window 1b, which is located between the bottom of the internal space of the filter box 1 and the liquid level window 1a, and is closer to the bottom of the internal space of the filter box 1; the filter box 1 also has a waste pipe 7, on which a second control valve 71 is installed, and the waste pipe 7 is connected to the bottom of the internal space of the filter box 1.
[0056] The amount of adsorbed impurities can be observed through the liquid level window 1 a , and when the amount of impurities is large, the impurities can be discharged by opening the second control valve 71 .
[0057] like Figure 5 As shown, in this embodiment, the liquid level window 1a and the impurity window 1b both include a transparent plate 11 sealed and mounted on the side wall of the filter box 1 and a riot blind plate 12 detachably mounted on the outside of the transparent plate 11. The transparent plate 11 may be glass, and the riot blind plate 12 is designed so that the use is not affected even if the transparent plate 11 is broken.
[0058] This embodiment also discloses a filtering system for graphite membrane, including the tar and dust filtering mechanism of this embodiment.
