DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] The embodiment of the utility model provides a defluorination material regeneration device 10 and a waste gas defluorination device 20. The waste gas defluorination device 20 is suitable for treating fluorine-containing waste gas and is easy to operate. The defluorination material regeneration device 10 can recycle the defluorination material and reduce the consumption of the defluorination material. In order to more clearly describe the defluorination material regeneration device 10 and the waste gas defluorination device 20 provided in this embodiment, the defluorination material regeneration device 10 and the waste gas defluorination device 20 are used as an example to specifically describe the defluorination of waste gas using the defluorination material as an alkaline washed zirconium sulfate material.

[0025] like Figure 1 As shown, the defluorination material regeneration device 10 provided in the embodiment of the utility model includes, for example, a reaction body 100 , a defluorination unit 110 , an alkaline solution tank 120 and a sulfuric acid tank 130 .

[0026] Specifically, the reaction body 100 has, for example, an inner cavity 101. The reaction body 100 is, for example, provided with a first quick-release structure 104, and the defluorination unit 110 is, for example, provided in the inner cavity 101. Figure 3As shown, the defluorination unit 110 is provided with a second quick-release structure 1101, and the first quick-release structure 104 is detachably connected to the second quick-release structure 1101. The alkali solution tank 120 and the sulfuric acid tank 130 are respectively provided on the reaction body 100 and are connected to the inner cavity 101 respectively.

[0027] Wherein, the defluorination unit 110 includes, for example, a defluorination material, and the defluorination material is, for example, a basic zirconium sulfate material. In order to remove fluorine from the fluorine-containing waste gas, the alkaline-washed zirconium sulfate reacts with the fluorine-containing waste gas to undergo a defluorination reaction. During the defluorination reaction, the alkaline-washed zirconium sulfate reacts chemically with the fluorine in the fluorine-containing waste gas, and the generated products include, for example, zirconium fluoride (ZrF4) solid and other fluorine-containing composite salt solutions. In order to regenerate the defluorination unit 110 after the defluorination treatment, it is necessary to first add an alkali solution to the defluorination unit 110 after the defluorination treatment for backwashing treatment. The products generated by the backwashing treatment include, for example, zirconium dioxide and a fluoride solution. After the backwashing treatment is completed, sulfuric acid is added to the defluorination unit 110 after the backwashing treatment. The zirconium dioxide can be acidified and transformed with sulfuric acid to generate regenerated alkaline-washed zirconium sulfate and fluorozirconic acid solution, etc., that is, the regeneration includes the process of backwashing treatment and acidification transformation treatment. The regenerated alkaline-washed zirconium sulfate can continue to be used for the defluorination treatment of the fluorine-containing waste gas, and the fluoride solution can be further treated for recycling.

[0028] Among them, the inner cavity 101 of the reaction body 100 is used to accommodate the defluorination unit 110 and provide a regeneration reaction space. The first quick-release structure 104 and the second quick-release structure 1101 are, for example, detachable structures that meet the needs of quick disassembly, such as quick cards, screw pins and flanges. The number and structure of the first quick-release structure 104 match the number and structure of the second quick-release structure 1101. The number of the first quick-release structure 104 and the second quick-release structure 1101 can be set according to actual needs and are not limited here. The design of the detachable connection allows the disassembly and installation of the defluorination unit 110, which is convenient for regeneration and replacement. The defluorination unit 110 is, for example, a defluorination unit after a defluorination reaction occurs. Specifically, the defluorination unit before the defluorination reaction is placed in a reaction device for defluorination, and the exhaust gas is passed into the interior of the reaction device and then undergoes a defluorination reaction with the defluorination unit. The defluorination unit 110 after the defluorination reaction is pulled out and placed in the defluorination material regeneration device 10 for a regeneration reaction. The defluorination unit 110 is, for example, filled with a specific defluorination material, where the defluorination material is an alkali-washed zirconium sulfate material. The defluorination unit 110 contacts the exhaust gas in the reaction tower and removes fluoride in the exhaust gas through chemical reactions. The alkali solution tank 120 is used to provide alkali solution to promote the aforementioned backwashing process. The sulfuric acid tank 130 is used to provide sulfuric acid to promote the aforementioned acidification transformation process. Specifically, the alkali solution tank 120 and the sulfuric acid tank 130 are, for example, respectively provided with valves, so that the operator can open and close the corresponding tanks and the flow rate of the liquid as needed, ensuring the reliability of the regeneration process and improving the flexibility of operation. In some embodiments, the alkali solution tank 120 and the sulfuric acid tank 130 are, for example, high-level tanks, and the liquid (such as alkali solution or sulfuric acid) stored in the high-level tank is transported to the device by gravity self-flow.

[0029] The defluorination material regeneration device 10 includes, for example, a first reaction state and a second reaction state. When the defluorination material regeneration device 10 is in the first reaction state, the alkali liquid tank 120 outputs alkali liquid to the defluorination unit 110. When the defluorination material regeneration device 10 is in the second reaction state, the sulfuric acid tank 130 outputs sulfuric acid to the defluorination unit 110. Specifically, in the first reaction state, the alkali liquid tank 120 outputs alkali liquid to the defluorination unit 110, and the alkali liquid reacts chemically with zirconium fluoride (ZrF4) to generate zirconium dioxide and fluoride solution. In the second reaction state, the sulfuric acid tank 130 outputs sulfuric acid to the defluorination unit 110, and zirconium dioxide can be acidified and transformed with sulfuric acid to generate regenerated alkali-washed zirconium sulfate and fluorozirconic acid solution, etc. The regenerated alkali-washed zirconium sulfate can continue to be used for defluorination treatment of fluorine-containing waste gas, and the fluoride solution can be further processed for recycling.

[0030] In the embodiment of the utility model, a defluorination unit 110 is arranged in the inner cavity 101 of the reaction body 100, and a first quick-detachment structure 104 and a second quick-detachment structure 1101 are arranged, so that the defluorination unit 110 is detachably connected to the reaction body 100 through the first quick-detachment structure 104 and the second quick-detachment structure 1101. When the defluorination unit 110 is removed from the reaction body 100, the defluorination unit 110 can be used in a defluorination device for defluorination treatment of waste gas to remove fluorine in the waste gas. For example, the defluorination unit 110 includes a basic zirconium sulfate material. The basic zirconium sulfate can be used to chemically react with fluorine in the fluorine-containing waste gas, and the generated products include, for example, zirconium fluoride solid and other fluorine-containing composite salt solutions. After the defluorination treatment is completed, the defluorination unit 110 can be regenerated in the reaction body 100 of the defluorination material regeneration device 10. Specifically, the defluorination unit 110 after the defluorination treatment is completed is first connected to the reaction body 100 through the first quick-detachment structure 104 and the second quick-detachment structure 1101, and then the alkali solution tank 120 is opened, so that the defluorination material regeneration device 10 is in the first reaction state. In the first reaction state, the alkali solution tank 120 outputs alkali solution to the defluorination unit 110, and the alkali solution reacts chemically with zirconium fluoride to generate zirconium dioxide and fluoride solution. Then the sulfuric acid tank 130 is opened, so that the defluorination material regeneration device 10 is in the second reaction state. In the second reaction state, the sulfuric acid tank 130 outputs sulfuric acid to the defluorination unit 110, and zirconium dioxide can be acidified and transformed with sulfuric acid to generate regenerated alkaline washed zirconium sulfate and fluorozirconic acid solution, etc. The regenerated alkaline washed zirconium sulfate can continue to be used for defluorination treatment of fluorine-containing waste gas, and the fluoride solution can be further processed for recycling. In this way, since the defluorination unit 110 can be easily disassembled, the defluorination unit 110 can not only be regenerated in the defluorination material regeneration device 10, but also can be disassembled from the defluorination material regeneration device 10 and transferred to other defluorination equipment (such as the waste gas defluorination equipment 20) to defluorinate the fluorine-containing waste gas, thereby increasing the operational flexibility and the scope of use of the defluorination unit 110, and allowing the used defluorination unit 110 to be recycled, reducing the frequency and cost of replacing the defluorination unit 110.

[0031] Specifically, the defluorination material regeneration device 10 further includes, for example, a first collecting tank 140 and a second collecting tank 150, which are respectively arranged at the bottom of the reaction body 100 and are respectively connected to the inner cavity 101. The first collecting tank 140 is used to collect the liquid after the reaction in the inner cavity 101 when the defluorination material regeneration device 10 is in the first reaction state, and the second collecting tank 150 is used to collect the liquid after the reaction in the inner cavity 101 when the defluorination material regeneration device 10 is in the second reaction state. Specifically, when the defluorination material regeneration device 10 is in the first reaction state, in the first reaction state, the alkali liquid tank 120 outputs the alkali liquid to the defluorination unit 110, and the alkali liquid reacts chemically with zirconium fluoride to generate zirconium dioxide and fluoride solution. After the reaction is complete, the first collecting tank 140 is opened, and the first collecting tank 140 is used to collect the fluoride solution so that the fluoride solution can be further processed and recycled. When the defluorination material regeneration device 10 is in the second reaction state, the sulfuric acid tank 130 outputs sulfuric acid to the defluorination unit 110, and zirconium dioxide can be acidified and transformed with sulfuric acid to generate regenerated alkaline washed zirconium sulfate and fluorozirconic acid solution, etc. The second collection tank 150 is used to collect waste solutions such as fluorozirconic acid solution, thereby reducing waste generation and meeting the requirements of environmental protection and sustainable development.

[0032] Specifically, the reaction body 100 has two opposite ends, the alkali liquid tank 120 and the sulfuric acid tank 130 are, for example, respectively arranged on opposite sides of the reaction body 100, the first collecting tank 140 and the second collecting tank 150 are, for example, respectively arranged on opposite sides of the reaction body 100, and the alkali liquid tank 120 and the second collecting tank 150 are, for example, located on the same side of the reaction body 100. That is, the alkali liquid tank 120 and the first collecting tank 140 are arranged diagonally, and the sulfuric acid tank 130 and the second collecting tank 150 are arranged diagonally, so that the flow path of the fluid is optimized, so that the reaction is more sufficient. Of course, the positions of the alkali liquid tank 120, the second collecting tank 150, the sulfuric acid tank 130 and the first collecting tank 140 can be set according to the actual structure of the product, and are not specifically limited here.

[0033] Specifically, the defluorination unit 110 includes, for example, a housing 111 and a defluorination filler 112. The housing 111 is, for example, a cylindrical structure made of plastic or metal with no covers at both ends. The second quick-release structure 1101 is, for example, disposed on the housing, and the housing 111 is, for example, detachably connected to the reaction body 100 through the first quick-release structure 104 and the second quick-release structure 1101. The defluorination filler 112 is, for example, disposed inside the housing 111, and the defluorination filler 112 is, for example, connected to the inside of the housing 111 by welding, and the specific connection method is not limited here.

[0034] Specifically, the defluorination filler 112 includes, for example, a Raschig ring filler and a defluorination material, the Raschig ring filler is arranged inside the shell 111, and the defluorination material is arranged on the surface of the Raschig ring filler. In the specific manufacturing process, the Raschig ring filler matrix is ​​first manufactured and the defluorination material is pretreated, and then the pretreated defluorination material is evenly coated or impregnated on the surface of the Raschig ring filler matrix, or the material is directly sprayed on the filler surface by spraying technology, and then the manufactured defluorination filler 112 is fixed inside the shell 111. Of course, the manufacturing method of the defluorination filler 112 can be selected according to the different defluorination materials and actual needs, and is not specifically limited here.

[0035] Preferably, the Raschig ring filler is a honeycomb filler. The honeycomb structure provides more contact area for gas and liquid, which helps to improve the efficiency of chemical reaction. And the honeycomb filler can evenly disperse the gas and liquid, reduce local dead zones, and ensure that the active area of ​​the entire filler layer is fully utilized. Of course, the Raschig ring filler can also be other shapes, which can be specifically designed according to different defluorination materials and actual needs, and is not limited here.

[0037] Specifically, the device body 200, for example, has an outer shell, and the device body 200 is used to provide a space for the defluorination reaction of the waste gas. The device body 200, for example, is provided with an air inlet 202 for introducing waste gas and an air outlet 203 for discharging the defluorinated gas.

When the outer shell 111 is connected to the device body 200 through the third quick-release structure 210 and the second quick-release structure 1101, the outer shell 111 is, for example, connected to the shell of the device body 200 so that the outer shell 111 can be used as a component of the device body 200. The waste gas introduced by the air inlet 202 enters from one end of the lumen of the defluorination unit 110 and reacts with the defluorination material, and then passes through the other end of the lumen of the defluorination unit 110 and is discharged from the air outlet 203. The detachable connection design allows the defluorination unit 110 to be disassembled and installed, which is convenient for regeneration and replacement.

[0038] In some embodiments, after the used defluorination unit 110 is regenerated in the defluorination material regeneration device 10, the defluorination unit 110 can be easily disassembled from the reaction body 100 through the first quick-detachment structure 104 and the second quick-detachment structure 1101, and then connected to the equipment body 200 through the third quick-detachment structure 210 and the second quick-detachment structure 1101, and the fluorine-containing waste gas is defluorinated in the equipment body 200, which increases the flexibility of operation and the scope of use of the defluorination unit 110, and can make the used defluorination unit 110 be recycled, reducing the frequency and cost of replacing the defluorination unit 110.
