In recent years, Zhejiang Huate Environmental Protection Equipment Ind. Co. has constantly strengthened the technical research. According to the statistics, up to now, there has been fifteen state invention patents only in the field of wet FGD technology developed by Mr. Chen Minglou, our general manager, the Research Fellow. While our company achieved the invention patents, the infringements upon our rights for our patent technology happened. And especially the patent right for rotating device, one of the techniques in wet FGD two-period absorbing and catching method equipment, was infringed several times.

The detailed content is in the report: No Infringements upon Environmental Patents (Science and Technology Daily Dem. 25, 2001)

 　　A national meeting to spread the SMLXW series of wet efficiently desulphurizing and dust-collecting equipment was held in Yandang Mountains of Zhejiang Province.
