Guangdong Huiyun Titanium Industry won the title of "Second Prize of Guangdong Environmental Protection Science and Technology Award"

On January 12, it was learned from Guangdong Huiyun Titanium Industry Co.
, Ltd.
that the winners of the 2022 Guangdong Environmental Protection Science and Technology Award were announced by the Guangdong Environmental Science Society, and the project of "in-depth development and application of titanium dioxide by-products based on sulfur chemical" jointly completed by Shenzhen Changlong Technology Co.
, Ltd.
, Central South University, Guangdong Huiyun Titanium Industry Co.
, Ltd.
and South China University of Technology won the second prize
.

According to He Mingchuan, general manager of Huiyun Titanium Industry, the project is mainly for the domestic titanium dioxide by-product green alum and waste sulfuric acid resource research, greatly improve its utilization value and reduce the amount of titanium dioxide by-product pollutants disposal, to achieve the sustainable use of by-products, and to make sulfur chemical titanium dioxide by-product green alum and waste sulfuric acid realize resource utilization to produce high value-added iron products, extend the sulfur chemical production titanium dioxide industry chain
。 A total of 13 enterprises such as Huiyun Titanium Industry, Yuxing Chemical, Daoen Titanium Industry, Jinmao Titanium Industry and Nanjing Titanium Industry have been provided with by-product resource disposal technology, consuming 1.
8055 million tons of titanium dioxide by-product green alum and 510,800 tons
of waste sulfuric acid.

The innovation of the project is: first, the refining and application
of titanium dioxide by-product green alum.
Using titanium dioxide by-product green alum as raw material, saturated dissolution and drying technology was developed to prepare refined green alum and dry green alum
.
The second is the preparation of active polyferric sulfate reinforced flocculant and the development of
continuous production process.
The new production process of active polyferric sulfate introduces efficient gas-liquid mixer and separation equipment
by improving the internal structure of the reactor.
The third is the development and application
of multi-core enhanced flocculants and composite precipitants based on active polyferric sulfate.
The fourth is the development of titanium dioxide by-product waste acid resource technology development
.
The new technology of preparing high dehydrated gypsum from titanium dioxide waste acid proposes the seed cycle technology, and adopts the process of "calcium carbonate-calcium oxide two-stage neutralization-flocculation-sludge reflux"
.

He Mingchuan said that since the establishment of Huiyun Titanium Industry, the company has adhered to innovation-driven re-empowerment, strengthened the main position of enterprise innovation, continuously increased the intensity of research and development and protection of intellectual property rights, and under the leadership of He Mingchuan Innovation Studio, which won the title of "Model Worker and Craftsman Talent Innovation Studio", it has continuously introduced policy benefits and financial living water into the company's innovation soil, accelerated the transfer and transformation of scientific and technological innovation achievements, strived to enhance the vitality of enterprise innovation, and continuously helped the company become a leading domestic and international first-class white powder green
