New electronic grade (UP grade) nitric acid purification equipment

Hebi Jinxing Quartz Glass Instrument Co., LTD., after more than 30 years of practical experience, has successfully developed electronic grade (UP) nitric acid production equipment, its technology has the top level in China. Technical characteristics are as follows:

1, the use of industrial grade nitric acid raw materials 98%, direct rectification and then add pure water dilution to 68%-70%, power consumption per ton of 150kw.h/t, replacing the current domestic most manufacturers using 70% industrial grade nitric acid as raw materials, the output of the product re-distillation purification to UP level electronic grade nitric acid two-step production process, power consumption per ton of 900kw.h/t.

2, the new electronic grade (UP) nitric acid production device, compared with the old production device, the power consumption of one ton of finished products is reduced by 60%.

3, the new production device produces a ton of electronic grade (UP) nitric acid power consumption of 150kw.h/t, calculated according to the average electricity cost of 0.6 yuan /kw, electricity consumption of 90 yuan per ton. Steam heating requires 0.8 tons of steam per ton of production, steam price is calculated according to 200 yuan/ton, and the steam cost per ton of nitric acid reagent is 160 yuan/ton. The use of electric heating production can save about 70 yuan/ton than steam heating, and the cost is reduced by 43%.

4, the structure of the production device comparison, electric heating nitric acid production device uses high temperature resistance, corrosion resistance, excellent chemical stability of quartz glass material, on-site welding without a flange connection, good sealing, long service life of the equipment, safety, environmental protection; The steam heating nitric acid production unit adopts borosilicate glass with low temperature resistance, and all parts are connected by flanges. The tightness is poor, and it is easy to produce running, bubbling, dripping and leakage. It causes serious pollution of the production environment, and the glass mechanical strength is poor and easy to damage. Because the flange fasteners are metal materials, they are easy to rust, difficult to disassemble during maintenance, and inconvenient to replace parts. What is more serious is that high borosilicate glass is easy to burst in the case of sudden cooling and sudden heating, which brings hidden dangers to production safety.

5, electric heating quartz production device stability is good, excellent product quality, steam heating stability is poor, will directly affect the quality of products, especially the higher the level of production products, the more difficult to adapt to the steam heating method.

Based on the above analysis, it is not difficult to see that the high-purity quartz glass production device of high-purity electronic grade nitric acid is compared with the high-borosilicate glass device, the production device has excellent material, safety, environmental protection, good product quality and stability, low operating cost, long equipment service life, and no pollution in the production environment. After the new electronic grade nitric acid production equipment was introduced to the market, it was praised by many manufacturers at home and abroad. The new electronic grade nitric acid production device produced by our company is widely selected, which helps more enterprises to improve product quality, and plays a vital role in reducing costs and improving the economic benefits of enterprises.
