由河北省沧县科学研究所发明的“铁狮牌”晶体管高压静电除尘器使用现场考察会于1990年4月24日在广东省高州县水库水泥厂及化州县水泥厂召开。参加现场考察会的有国家科委、国家环保局的有关领导及全国水泥情报总网的代表,还有来自苏联的电子专家和联合国驻华新闻机构的代表。通过现场考察,与会中外专家一致认为:铁狮牌晶体管高压静电除尘器具有结构简单、除尘效率高、运转费用低、安全可靠、维护管理方便等特点。孩产品已获国家专利,并已正式列入国家科委1990年技术推广计划。该晶体管静电除尘器利用软特性电源供
The “Tieshi Brand” transistor high-voltage electrostatic precipitator site-inspection meeting, invented by the Gansu County Institute of Science and Technology in Hebei Province, was held on April 24, 1990 at the Reservoir Cement Factory of Gaozhou County and Huazhou Cement Factory. Participants in the on-site inspection meeting were the leaders of the State Science and Technology Commission and the National Environmental Protection Agency, representatives of the National Cement Intelligence Network, and electronic experts from the Soviet Union and representatives of the United Nations News Agency in China. Through on-site inspections, experts from both home and abroad agreed that: Tishi Brand transistor high-voltage electrostatic precipitators have the characteristics of simple structure, high dust removal efficiency, low operating cost, safety and reliability, and convenient maintenance and management. Children’s products have obtained national patents and have been formally included in the State Council’s 1990 technology promotion plan. The transistor electrostatic precipitator utilizes a soft characteristic power supply
