Zhejiang Zhongbo Developed New Sulfur Dioxide Control Technology    

With an investment of nearly RMB100 million and an effort of eight years, Zhejiang Zhongbo Taiji Environmental Protection Facility Co., Ltd. has finally developed the DS-sulfur dioxide flue gas control technology. The technology has already passed the state-class appraisal. The result of the field monitoring made by Zhejiang Environmental Protection Monitoring Center on the functioning of the technology and equipment shows that flue gas after purification has reached the national Class II standard and the desulfurization effect is as high as 98.9%.
   The most outstanding feature of the technology lies in the cyclic utilization of resources. Industrial residue here is used as absorbing agent to conduct high-effect desulfurization. Sulfur dioxide containing residue can also be made through a simple process into "base fertilizer" or sulfur-enriched biological fertilizer to ameliorate saline, alkaline, sandy and waste land.
   The core unit of the technology has a nozzle-free structural design. The entire polymer has one-time shaping. Complicated steps such as corrosion prevention and maintenance are removed. The service life of major equipment is therefore extended and technical problems such as easy blocking, easy wear and easy corrosion of spray tower and bubble column are thoroughly solved. The technology has gained extensive applications in metallurgical, power and chemical enterprises in Hunan, Zhejiang and Sichuan provinces.
