Description

Technical Field

[0001] The present invention relates to the technical field of environmentally friendly treatment of inorganic fluorides, and more particularly to an environmentally friendly treatment system for inorganic fluoride wastes with reduced hazards. Background Art

[0002] The electronics industry generates various types of liquid waste chemicals during the production process. For example, inorganic fluoride waste is generated during the production of integrated circuit panels. Inorganic fluoride waste is also a hazardous waste. Hazardous waste is one of the important sources of pollution that endangers the human ecological environment and human health. If it is not effectively disposed of and discharged at will, 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 health. Therefore, the harmless treatment and final safe disposal of hazardous waste have attracted great attention.

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

[0004] When selecting a metal organic framework as an adsorbent, although the ultra-high specific surface area and adjustable pore structure of the metal organic framework give it a high adsorption capacity (greater than 10 mg / g), its cost and stability limit its industrial application. Therefore, an inorganic fluoride waste treatment device in the prior art (application number 202020983501.7) discloses "a plurality of fiber adsorption balls are placed inside a fixed mesh frame, and rare earth metal oxides are bonded to the outside of the fiber adsorption balls". It is difficult to apply it in industry due to cost and stability. When selecting a modified zeolite as an adsorbent, the modified zeolite is loaded with Al 3+ 、La 3+ The invention relates to a novel inorganic fluoride waste treatment device, which can enhance the selectivity of the modified zeolite by metal ions, can work under neutral conditions (pH 6-7), has both low cost and renewability, and can be applied to the industrial field. However, if the method disclosed in the prior art of an inorganic fluoride waste treatment device of "a waterproof motor drives multiple fiber adsorption balls to rotate and contact with sewage" is still adopted, the contact between the modified zeolite and the sewage will be insufficient; because the contact between the modified zeolite and the sewage requires the speed of the sewage passing through the modified zeolite to be controlled within the optimal range of 2-5BV / h (bed volume / hour), and the contact time between the sewage and the modified zeolite to be controlled within 30-60 minutes.

[0016] Compared with the prior art, the environmentally friendly inorganic fluoride waste treatment system of the present invention reduces hazards.

[0017] 1) When the sewage pipe group is used to discharge the chemical waste liquid containing inorganic fluoride waste normally, the driving component included in the support frame is started to drive the multiple environmental protection treatment pipes slidingly assembled on the support frame to perform intermittent closed-loop circulation along the support frame. In this process, multiple environmental protection treatment pipes will be used one by one to receive the chemical waste liquid containing inorganic fluoride waste transported from the sewage pipe group; and the multiple environmental protection treatment pipes will form multiple independent treatment units in turn, and in the closed-loop circulation movement along the support frame, promote the chemical waste liquid containing inorganic fluoride waste.

[0043] The environmental treatment tube 400 is internally installed with modified zeolite, which is used to adsorb and remove inorganic fluorides to reduce harm;

[0044] It should be noted that the modified zeolite is loaded with Al 3+ 、La 3+The metal ions enhance the selectivity, remove inorganic fluoride by adsorption and reduce the harm;

[0045] A sewage pipe assembly 100 is installed on one side of the support frame 200. The sewage pipe assembly 100 is used to discharge chemical waste liquid containing inorganic fluoride waste. A feed telescopic pipe controlled by a hydraulic telescopic rod is provided at the front end of the sewage pipe assembly 100. The hydraulic telescopic rod is used to control the feed telescopic pipe to extend and retract to complete the detachable docking with the environmental protection treatment pipe 400, thereby supplying the chemical waste liquid containing inorganic fluoride waste to the environmental protection treatment pipe 400.

[0047] Therefore, for a modified zeolite that is both low-cost and renewable and can be applied to the industrial field, if the method disclosed in the prior art of an inorganic fluoride waste treatment device is used, which is "a waterproof motor drives multiple fiber adsorption balls to rotate and contact with sewage", the modified zeolite will not be in sufficient contact with the sewage. The present application can achieve the following:

[0048] When the sewage pipe group 100 is used to discharge the chemical waste liquid containing inorganic fluoride waste normally, the driving component included in the support frame 200 is started to drive the multiple environmental protection treatment pipes 400 slidingly assembled on the support frame 200 to perform intermittent closed-loop circulation along the support frame 200. In this process, multiple environmental protection treatment pipes 400 will be used to receive the chemical waste liquid containing inorganic fluoride waste transported from the sewage pipe group 100 one by one; and the multiple environmental protection treatment pipes 400 will form multiple independent treatment units in turn, and in the closed-loop circulation movement along the support frame 200, the chemical waste liquid containing inorganic fluoride waste is promoted. The chemical waste liquid containing fluoride waste is fully contacted with the modified zeolite; the chemical waste liquid containing inorganic fluoride waste and the modified zeolite are fully contacted in terms of contact time and contact speed, and the modified zeolite is improved to fully contact and adsorb to remove inorganic fluoride, thereby reducing harm; after the adsorption and removal is completed, the outlet pipe group 300 will be used to receive the fluid treated by the environmental protection treatment pipe 400; on the basis of ensuring that the sewage pipe group 100 can discharge the chemical waste liquid containing inorganic fluoride waste normally without stopping, efficient, comprehensive and full contact adsorption to remove inorganic fluoride and carry out normal production activities in the electronics industry.

When the driving motor 230 drives the plurality of sprockets to rotate, the chains move in a closed loop along the guide groove 220.

[0058] Regarding the drive motor 230, the sprocket and the chain, it should be noted that the drive motor 230, the sprocket and the chain are prior art, as are the power supply and wiring methods of the drive motor 230. Their detailed structures can be found in existing literature and journals, and they can also be purchased directly on the market, or components purchased on the market can be assembled, etc.; they are not intended to be protected by the present invention and will not be elaborated on herein.
