Problems solved by technology

[0003] The existing hazardous waste containing nickel and fluorine will cause great pollution to the environment when it is processed, and it will cost a lot of money when it is processed, and the existing products are filled manually and mechanically. The installation of bottle caps requires high labor costs and low filling efficiency. Therefore, we propose a device and process for by-product ammonium bifluoride and potassium fluoride from NF3 production to solve the above problems

Embodiment Construction

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention.

[0030] refer to Figure 1-5 , a device for producing ammonium bifluoride and potassium fluoride by-products from NF3 production, including a workbench 1, the four corners of the lower end of the workbench 1 are fixed with bearing rods 14, which is convenient for the stable support of the workbench 1, and the middle part of the upper end of the workbench 1 There is a groove, and a conveying mechanism is arranged in the groove. Electric push rods 10 are fixed on both sides of the upper end of the workbench 1. One end of the two electric push rods 10 is fixed with a lifting block 3. The two electric push rods 10 pass through One end drives two lifting blocks 3 to move u...

Abstract

The invention discloses a device and process for producing byproducts ammonium bifluoride and potassium fluoride from NF3 production, and the device comprises a workbench; a groove is formed in the middle of the upper end of the workbench, a conveying mechanism is arranged in the groove, electric push rods are fixed to the two sides of the upper end of the workbench, lifting blocks are fixed to one ends of the two electric push rods, a lifting plate is fixed to one ends of the two lifting blocks together, and a mounting frame is fixed to one side of the upper end of the lifting plate. The invention further provides a process for producing ammonium bifluoride and potassium fluoride as byproducts in NF3 production. Filling and installation of the bottle cap can be achieved through intermittent movement of the bottle body, the labor cost is effectively saved, dust is prevented from flying out, the production efficiency is improved, hazardous waste containing nickel and fluorine can be eliminated and converted into by-products, environmental pollution is reduced, and the method can convert the original hazardous wastes needing to be treated into byproducts, and has certain economic benefits.

Description

technical field [0001] The invention relates to the field of fine chemicals, in particular to a device and a process for by-producting ammonium bifluoride and potassium fluoride from NF3 production. Background technique [0002] The wastewater produced in electrolysis production contains a large amount of ammonium bifluoride (ammonium fluoride), nickel fluoride, ferrous fluoride, and sponge nickel, copper, iron, etc. These substances, except iron, are all toxic substances. It has been confirmed by people that Ni2+ (Ni) has a strong carcinogenic effect, and F- also has a strong toxicity. my country attaches great importance to environmental protection, and Ni2+ and F- are listed as the first and second pollution control indicators respectively ( GB 8978-96), that is to say, the maximum allowable discharge concentration of total nickel is 1.0mg / L, and fluoride is 10mg / L. A series of studies on fluorine-containing wastewater have been carried out at home and abroad, and good p...
