Description

Technical Field

[0001] The present invention relates to the technical field of environmental protection treatment of inorganic fluorides, and more specifically, to an environmental protection treatment system for inorganic fluoride waste that reduces hazards. Background Art

[0002] Various liquid waste chemical solutions are generated during the production process in the electronics industry. For example, inorganic fluoride waste is generated during the production of integrated circuit panels. Inorganic fluoride waste is also one of the hazardous wastes, and hazardous waste is one of the important pollution sources that endanger the human ecological environment and human health. If it is not effectively disposed of and is discharged randomly, it will not only cause serious impacts and damage to the water environment, air environment, and soil environment, but also pose a direct threat to people's physical health. Therefore, the problem of harmless treatment and final safe disposal of hazardous waste has attracted great attention.

[0003] The core of the environmental protection adsorption treatment technology for inorganic fluorides lies in using the surface active sites of porous adsorption materials to selectively capture fluoride ions in wastewater through physical adsorption, chemical bonding, or ion exchange, etc. The adsorbents include activated alumina, modified zeolite, hydroxyapatite, and metal-organic frameworks (MOFs).

[0004] When selecting metal-organic frameworks as adsorbents, although the ultra-high specific surface area and adjustable pore structure of metal-organic frameworks endow them with high adsorption capacity (greater than 10 mg / g), their cost and stability limit their industrial application. Therefore, an existing inorganic fluoride waste treatment device (application number 202020983501.7) discloses that "a plurality of fiber adsorption balls are placed inside a fixed wire frame, and rare earth metal oxides are bonded to the outside of the fiber adsorption balls", which is difficult to apply in industry in terms of cost and stability. When selecting modified zeolite as an adsorbent, the modified zeolite enhances selectivity by loading metal ions such as 3+ Al 3+ La, etc., and can work under neutral conditions (pH 6 - 7), with both low cost and renewable properties, and can be applied to the industrial field. However, if the method disclosed in an existing inorganic fluoride waste treatment device, "driving a plurality of fiber adsorption balls to rotate and contact the sewage by a waterproof motor", is still adopted, the contact between the modified zeolite and the sewage will be insufficient; because for the contact between the modified zeolite and the sewage, the flow rate of the sewage through the modified zeolite needs to be controlled within the optimal range of 2 - 5 BV / h (bed volume / hour), and the contact time between the sewage and the modified zeolite needs to be controlled within 30 - 60 minutes. Summary of the Invention

[0041] In order to make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below in conjunction with specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

The plurality of environmental protection treatment pipes 400 are driven by a driving component included on the support frame 200 to perform a closed-loop circular rotation on the support frame 200;

[0043] Modified zeolite is installed inside the environmental protection treatment pipe 400, and the modified zeolite is used to adsorb and remove inorganic fluoride to reduce hazards;

[0044] It should be supplemented and explained here that: The modified zeolite is loaded with Al 3+ , La 3+Metal ions such as enhance selectivity, desorb and remove inorganic fluorides to reduce hazards;

[0045] A sewage discharge pipe group 100 is installed on one side of the support frame 200. The sewage discharge pipe group 100 is used to discharge chemical waste liquid containing inorganic fluoride waste. A feeding telescopic pipe controlled by a hydraulic telescopic rod is arranged at the front end of the sewage discharge pipe group 100. The hydraulic telescopic rod is used to control the telescopic movement of the feeding telescopic pipe to complete the detachable docking with the environmental protection treatment pipe 400, so as to provide the environmental protection treatment pipe 400 with chemical waste liquid containing inorganic fluoride waste.

[0046] An outlet water pipe group 300 is installed on the other side of the support frame 200.

It should be supplemented here that the detachable docking method of the outlet water pipe group 300 with the environmental protection treatment pipe 400 is the same as that of the sewage discharge pipe group 100, where the hydraulic telescopic rod is used to control the telescopic movement of the feeding telescopic pipe to complete the detachable docking with the environmental protection treatment pipe 400.

[0047] Therefore, for modified zeolites that are both low-cost and renewable and can be applied to the industrial field, if the method of "driving multiple fiber adsorption balls to rotate and contact with sewage" disclosed in an existing inorganic fluoride waste treatment device is adopted, it will cause the problem of insufficient contact between the modified zeolite and the sewage. This application can achieve:

[0048] When the sewage discharge pipe group 100 is used to normally discharge chemical waste liquid containing inorganic fluoride waste, start the drive assembly included on the support frame 200 to drive multiple environmental protection treatment pipes 400 slidably assembled on the support frame 200 to perform intermittent closed-loop circular rotation along the support frame 200. During this process, multiple environmental protection treatment pipes 400 will sequentially receive the chemical waste liquid containing inorganic fluoride waste conveyed by the sewage discharge pipe group 100 one by one; and the multiple environmental protection treatment pipes 400 will sequentially form multiple independent treatment units, and during the closed-loop circular movement along the support frame 200, it will promote the full contact between the chemical waste liquid containing inorganic fluoride waste and the modified zeolite; realize ensuring the full contact between the chemical waste liquid containing inorganic fluoride waste and the modified zeolite in terms of contact time and contact speed, improve the full contact adsorption of the modified zeolite to remove inorganic fluorides and reduce hazards; after the adsorption and removal are completed, use the outlet water pipe group 300 to receive the fluid after being treated by the environmental protection treatment pipe 400; achieve the ability to ensure the normal discharge of chemical waste liquid containing inorganic fluoride waste by the sewage discharge pipe group 100 without shutting down, and perform efficient, comprehensive and full-contact adsorption to remove inorganic fluorides and carry out normal production activities in the electronics industry.

[0049] Such as Figure 2As shown in the figure: The environmental protection treatment pipe 400 includes an environmental protection treatment pipe body 420. A water injection nozzle 410 is installed at one end of the environmental protection treatment pipe body 420, and a water outlet nozzle 450 is installed at the other end of the environmental protection treatment pipe body 420. Solenoid valves are installed inside both the water injection nozzle 410 and the water outlet nozzle 450.

[0050] The water injection nozzle 410 is used for detachably connecting with the feeding telescopic pipe and receiving the chemical waste liquid containing inorganic fluoride waste transported by the sewage discharge pipe group 100.

[0051] The water outlet nozzle 450 is used for detachably connecting with the water outlet pipe group 300 and receiving the fluid processed by the environmental protection treatment pipe 400.

[0052] As Figure 5 and Figure 9 shown in the figure: The environmental protection treatment pipe body 420 includes an outer treatment pipe body 4201 and an inner treatment pipe body 4202. The inner treatment pipe body 4202 is arranged inside the outer treatment pipe body 4201, and the axial centerlines of the outer treatment pipe body 4201 and the inner treatment pipe body 4202 are set on the same straight line.

[0053] A water inlet buffer cavity is reserved between the outer treatment pipe body 4201 and the inner treatment pipe body 4202. A sealing ring 4203 is respectively fixed on the inner treatment pipe body 4202 at both ends of the water inlet buffer cavity; Multiple water permeable holes 4204 are opened on the inner treatment pipe body 4202, and the multiple water permeable holes 4204 are arrayed on the main body of the inner treatment pipe body 4202.

[0054] As Figure 2 and Figure 3 shown in the figure: A reinforcing plate 440 is fixed on the environmental protection treatment pipe body 420. Multiple positioning blocks 430 are fixed on the reinforcing plate 440, and the positioning blocks 430 are in a "T" shape; The positioning blocks 430 are slidably assembled on the support frame 200.

[0055] The support frame 200 includes a support platform 210. Multiple guide grooves 220 are opened on the support platform 210, and the multiple guide grooves 220 correspond to the multiple positioning blocks 430 one by one; The support platform 210 is slidably assembled on the guide grooves 220; The guide grooves 220 are in a closed loop shape along the support platform 210.

[0056] As Figure 2 and Figure 3 shown in the figure: The driving assembly includes a driving motor 230 and multiple chains. The multiple chains correspond to the multiple guide grooves 220 one by one. The chains are movably laid inside the guide grooves 220, and a steel rope is sleeved outside the chains. The steel rope is used to improve the traction force of the chains; The positioning blocks 430 are fixed on the chains.

[0057] The drive motor 230 is installed on the support platform 210. A rotating shaft is fixed on the output shaft of the drive motor 230, and multiple sprockets are fixed on the rotating shaft. The multiple sprockets correspond to multiple chains one by one, and the sprockets are engaged on the chains. During the process of the drive motor 230 driving the multiple sprockets to rotate, the chains move in a closed-loop cyclic manner along the guide groove 220.

[0058] Regarding the drive motor 230, sprockets and chains, it should be noted that the drive motor 230, sprockets and chains belong to the prior art, and the power supply wiring method of the drive motor 230 also belongs to the prior art. Its detailed structure can be obtained from existing literature and periodicals, and it can also be directly purchased on the market, or components can be purchased on the market for assembly, etc. It is not what the present invention aims to protect and will not be elaborated in detail here. The sprockets and chains are not drawn in the drawings either.

[0059] Therefore, start the drive motor 230. The drive motor 230 is an intermittent motor. Through the power provided by the drive motor 230, the sprockets are used to transfer the power to the chains, and the chains are made to move in a closed-loop cyclic manner along the guide groove 220. The drive assembly is used to drive a plurality of environmental protection treatment pipes 400 slidably assembled on the support frame 200 to rotate intermittently in a closed-loop cycle along the support frame 200. During this process, a plurality of environmental protection treatment pipes 400 will successively receive the chemical waste liquid containing inorganic fluoride waste transported by the sewage discharge pipe group 100 one by one, and after the adsorption and removal are completed, the water outlet pipe group 300 will receive the fluid after being treated by the environmental protection treatment pipes 400.

[0060] As Figure 2 、 Figures 4 - 6 shown: An inorganic fluoride adsorption core 460 is installed inside the environmental protection treatment pipe 400, and the inorganic fluoride adsorption core 460 occupies three-quarters of the space inside the environmental protection treatment pipe 400. The inorganic fluoride adsorption core 460 is used to adsorb and remove inorganic fluoride to reduce hazards.

[0061] Therefore, since the inorganic fluoride adsorption core 460 occupies three-quarters of the space inside the environmental protection treatment pipe 400, the chemical waste liquid containing inorganic fluoride waste can be brought into contact with the modified zeolite in a suitable proportion. Combining the independent and sealed space of the environmental protection treatment pipe 400 and the cycle of the environmental protection treatment pipe 400 rotating in a cycle, sufficient contact time is given to the modified zeolite and the chemical waste liquid containing inorganic fluoride waste, which is beneficial for the inorganic fluoride adsorption core 460 to adsorb and remove inorganic fluoride to reduce hazards.

[0062] As Figures 6 - 8As shown: The inorganic fluoride adsorption core 460 includes a positioning tube 464 and a plurality of outer adsorption ridges 461. The plurality of outer adsorption ridges 461 are distributed in an annular array around the positioning tube 464. The outer adsorption ridges 461 are installed on the positioning tube 464. Water inlet grooves 4611 are formed on the outer adsorption ridges 461. The water inlet grooves 4611 are distributed along the outer adsorption ridges 461 and communicate with the inside of the positioning tube 464.

[0063] As Figures 6 - 8 and Figure 10 shown: Inside the outer adsorption ridges 461 around the outer periphery of the water inlet grooves 4611 is filled with modified zeolite. The modified zeolite is surrounded by a plurality of mesh plates 4612 contained in the outer adsorption ridges 461 to form a first modified zeolite filling area 500.

[0064] As Figures 6 - 8 and Figure 10 shown: The inorganic fluoride adsorption core 460 further includes an insertion tube 462. The insertion tube 462 is inserted inside the positioning tube 464. The axial centerlines of the insertion tube 462 and the positioning tube 464 are arranged on the same straight line.

[0065] A water pump 463 is installed at the end of the insertion tube 462. The water pump 463 is used to pump out the fluid inside the insertion tube 462 and pump it outside the inorganic fluoride adsorption core 460.

[0066] Regarding the water pump 463, it should be noted that the water pump 463 and the way of its power-on wiring also belong to the prior art. Its detailed structure can be known from existing literature and periodicals, and it can also be directly purchased on the market, or parts can be purchased on the market for assembly, etc. It is not what the present invention aims to protect and will not be elaborated in detail here.

[0067] As Figure 10 shown: Inside the gap between the insertion tube 462 and the positioning tube 464 is filled with modified zeolite. The modified zeolite is surrounded by an inner mesh cylinder and an outer mesh cylinder to form a second modified zeolite filling area 600.

[0068] Inside the insertion tube 462 is filled with modified zeolite. The modified zeolite is surrounded by the tube wall of the insertion tube 462 to form a third modified zeolite filling area 700.

[0069] A plurality of water pumping holes 4621 are formed on the main body of the insertion tube 462. The plurality of water pumping holes 4621 are distributed in an array along the main body of the insertion tube 462. The plurality of water pumping holes 4621 are used to connect the insertion tube 462 and the positioning tube 464.

[0070] Therefore, since the outer adsorption ridges 461 around the outer periphery of the water inlet tank 4611 are filled with modified zeolite, a plurality of modified zeolite filling areas I 500 are formed; in addition, the gap between the insertion tube 462 and the positioning tube 464 is filled with modified zeolite, forming the modified zeolite filling area II 600; and the insertion tube 462 is internally filled with modified zeolite, forming the modified zeolite filling area III 700; thus, a plurality of stable soaking areas are provided for the chemical waste liquid containing inorganic fluoride waste, realizing the contact surface and contact time between the modified zeolite and the chemical waste liquid containing inorganic fluoride waste, which is beneficial to full contact. The modified zeolite is enhanced in selectivity by loading metal ions such as Al 3+ and La 3+ to adsorb and remove inorganic fluoride and reduce hazards;

[0071] Start the water pump 463 at the end of the insertion tube 462. The water pump 463 mobilizes the flow of the chemical waste liquid containing inorganic fluoride waste inside the insertion tube 462, promoting the chemical waste liquid containing inorganic fluoride waste outside the inorganic fluoride adsorption core 460 to sequentially pass through the plurality of modified zeolite filling areas I 500 of the plurality of outer adsorption ridges 461, enter the modified zeolite filling area II 600 between the insertion tube 462 and the positioning tube 464, then pass through the modified zeolite filling area II 600 and enter the modified zeolite filling area III 700 inside the insertion tube 462, and finally return to the inside of the environmental protection treatment pipe 400 outside the inorganic fluoride adsorption core 460 through the water pump 463; realizing the provision of mobilization power to slowly mobilize the chemical waste liquid containing inorganic fluoride waste, and on the basis of ensuring high-efficiency adsorption and removal of inorganic fluoride through the optimal flow rate range, contact area and contact time, to efficiently treat the chemical waste liquid containing inorganic fluoride waste on a large scale.

[0072] In addition, the drain outlet of the water pump 463 is connected to the water inlet buffer cavity reserved between the outer treatment pipe body 4201 and the inner treatment pipe body 4202.
