The joint research team established by the Research Institute United Joint Stock Company has solved the industrial technical problem of low waste acid concentration efficiency through nearly four years of continuous research, and has formed a waste acid concentration and reuse technology with completely independent intellectual property rights.
It is understood that after relevant technical achievements are applied on site in Chongqing Titanium Industry, the operating stability of the device continues to improve, the recovery rate of waste acid has increased by more than 30 percentage points, the stable operation cycle of waste acid concentration has increased by 150%, and the production of titanium dioxide and titanium gypsum per ton has been reduced by 40%. Above, the cost of waste acid treatment is reduced, and the economic and social benefits are obvious.
With the increasing national environmental protection requirements and the urgent need for sulfuric acid titanium dioxide enterprises to reduce costs, waste acid treatment has become a key factor affecting the development of sulfuric acid titanium dioxide enterprises. Panzhihua Iron and Steel Co., Ltd. has adopted measures such as comprehensive utilization of waste acid after concentration and returning it to the acidolysis process to continuously improve the comprehensive utilization rate of waste acid. However, the industry problem of low waste acid concentration efficiency has not been effectively solved.
Panzhihua Steel's newly developed waste acid concentration technology has greatly improved the comprehensive utilization level of Panzhihua Steel's sulfuric acid titanium dioxide waste acid, reduced the processing cost and environmental protection pressure of waste acid neutralization to produce titanium gypsum, achieved a win-win situation in environmental protection and benefits, and improved Panzhihua Steel's comprehensive market competitiveness of sulfuric acid titanium dioxide.
