Efficient environmental protection and energy saving into the most popular titanium dioxide equipment "label"

Recently held in Wenzhou in 2021 titanium dioxide high-tech production equipment technology exchange meeting, from all walks of life in the industry, nearly 20 titanium dioxide production and equipment manufacturing experts and business representatives, around the industry's current survival and development environment and the development of technical equipment needs for exchange and discussion. Representatives believe that high efficiency, environmental protection, energy saving is currently the most popular titanium dioxide equipment "label".

Titanium White Union Secretary-General, titanium white sub-centre director Bi Sheng pointed out that the overall production scale of China's titanium dioxide industry, the level of production technology and equipment technology level are located in the world's forefront. However, the realization of the titanium dioxide production country to the production of a strong country, in terms of production equipment, to focus on high efficiency, energy saving, environmental protection of several elements, upstream and downstream enterprises work closely together to do fine and excellent industrial chain, improve the level of product innovation.

Titanium white alliance and titanium white sub-center chairman, Jinpu Titanium Co., Ltd. general manager Peng Anzheng said that titanium dioxide production enterprises are higher energy consumption per unit of product, unit emissions of chemical enterprises, in the background of the double carbon, will face more severe challenges. I hope that equipment manufacturing enterprises can start from the demand of titanium dioxide enterprises, and titanium dioxide enterprises resonate with the same frequency, research and development in line with the industry to reduce consumption and carbon of new technologies, new equipment.

At the meeting, for China's titanium dioxide production process status and development needs, a number of equipment enterprises brought their own fist products, and at the meeting by the attention.

Zhejiang Xuanda company successfully developed a vacuum concentration - salt analysis crystallization method to deal with titanium dioxide waste acid new technology, through the control of the crystallization process, to solve and improve the evaporation and crystallization device fouling blockage, solid-liquid separation difficulties, high sulfate moisture content, concentrated acid concentration of up to 80% or more, can achieve titanium dioxide waste acid resource utilization and maximize economic benefits. "The technology not only produces recyclable concentrated acid, but also has a small amount of sulphate by-products, which is highly available, and the secondary treatment costs are significantly reduced, so the economic benefits are significant when considering the whole process. Combined with the greater resource integration advantages that sulphur iron ore acid production will bring into play, it can be vigorously promoted and applied in the sulphuric acid titanium dioxide industry." The company's technical department Ding Changye said.

Jiangsu Anda company developed JDMC metal fiber high temperature bag dust collector has the advantages of low one-time investment, low operating costs, high efficiency of dry collection of titanium dioxide dust and low failure rate. At present, it has successfully obtained a number of demonstration project contracts for Inner Mongolia Dadi Yuntianhua, Guangdong Huiyun titanium industry, etc. The dry recovery efficiency of titanium dioxide from the tail gas of titanium dioxide calcination kiln reaches 99.9%, which has high economic value and can realize ultra-low emission of tail gas dust at the same time.

According to Mianyang Haotai Technology Co., Ltd. general manager Zhang Tai, the company developed a capacity of 5 ~ 6 tons / hour (40,000 ~ 50,000 tons / year), waste heat to make full use of the large steam powder production system, and has been used in a number of titanium dioxide manufacturers, to achieve satisfactory results. It can generally run for more than 5 years and achieve full automatic control and can be connected to the user's DCS.

At the meeting, Hong Jie, expert of the Titanium White Alliance and chief engineer of Shandong Dongjia Group, also introduced the experience of Dongjia Group on the comprehensive energy recovery of rotary kiln, gas powder and concentration of titanium dioxide production, the innovation of cooling device of metatitanic acid after hydrolysis and the recovery of waste heat, the recovery of black slag of acid digestion, the reuse of carbon dioxide in addition to hard combined water, etc.

The conference was hosted by the Titanium White Industry Technology Innovation Strategic Alliance and the Titanium White Sub-Centre of the Chemical Productivity Promotion Centre. (Content republished/sourced from: China Plastics Online/China Chemical News)
