Fuzhou University uses two-stage dehydration technology to produce anhydrous aluminum fluoride. The process first dehydrates 55% aqueous aluminum fluoride to 6% at a temperature of 300°C, and then dehydrates at a temperature of about 600°C to obtain 0.5% anhydrous aluminum fluoride. Two-stage dehydration can adopt integrated fluidized bed technology or combined technology of fluidized bed and rotary kiln to achieve the cycle and high-efficiency heat exchange between dry materials and drying media. At the same time, all indexes of anhydrous aluminum fluoride produced can reach the international advanced level. .
Compared with the introduction of dry process technology, the two-stage dewatering process to produce anhydrous aluminum fluoride technology has an unmatched price-performance ratio, and is particularly suitable for the transformation of existing aluminum fluoride plants in China. The sales price of anhydrous aluminum fluoride can generally be higher than the traditional wet sales price by more than 10%, and is approximately 500 yuan more. Annual output of anhydrous aluminum fluoride is 3,000 tons/year, and one year can create more benefits by 1.5 million yuan. The entire investment can be recovered in that year. At the same time, the new anhydrous aluminum fluoride product (water content is only 0.5%) has unparalleled competitiveness compared to traditional aluminum fluoride, especially in line with the needs of foreign aluminum plants, can open up the international market, and it must be in the aluminum plant in China. Application and development. Therefore, anhydrous aluminum fluoride has a very broad market prospect both domestically and internationally.
2. The chain plates are made of stainless steel and engineering plastics with a wide variety of materials and specifications, which can be selected according to the conveying materials and process requirements, which can meet the different needs of various industries;
3. The frame material is divided into aluminum profile, ordinary carbon steel and stainless steel.
4. Large conveying capacity, which can carry a large load, such as used in electric vehicles, motorcycles, generators and other industries;
5. The conveying speed is accurate and stable, which can ensure accurate synchronous conveying;
6. Chain conveyors can generally be washed directly with water or directly immersed in water. The equipment is easy to clean and can meet the hygiene requirements of the food and beverage industries;
7. Flexible equipment layout. Can complete horizontal, inclined and turning conveying on one conveying line;
8. The equipment has simple structure and easy maintenance.
At present, the methods for producing aluminum fluoride in various countries in the world are mainly dry and wet methods. The dry process produces anhydrous aluminum fluoride with water up to 0.6%, but the dry process investment is generally several times that of the wet process. An annual output of 10,000 tons of anhydrous aluminum fluoride requires investment of hundreds of millions, and the raw material requirements are also Relatively high. Wet method is a relatively traditional method of production. The obtained anhydrous aluminum fluoride has a water content of 7%. This method uses a large amount of fluoride salts, seriously pollutes the environment, and the index is low.
