According to a survey just released by the School of the Environment of Tsinghua University, the current total mercury consumption in China is about 1,000 tons, accounting for about 50% of the world total, and it has become the world's largest producer and consumer of mercury. The main mercury products and mercury-related processes are acetylene-based polyvinyl chloride production, thermometers, batteries, sphygmomanometers, and electric light sources. In addition, mining pillars, coal-fired, steel, nonferrous metals, cement, chemical and other pillar industries are also heavily involved in mercury. Among them, coal-fired power plants account for 33% of domestic mercury emissions, and other industrial boilers account for 19% of mercury emissions. Experts predict that the coal consumption of coal-fired power plants will double in 2020. If no control measures are taken, domestic mercury pollution will be doubled.
A vortex pump (also called a vortex pump) is a vane pump. It is mainly composed of impeller, pump body and pump cover. It is suitable for occasions requiring small flow (1 to 40 cubic meters per hour) and high lift (up to 250 meters).
A vortex pump is a vane pump. It is mainly composed of impeller, pump body and pump cover. The impeller is a disc with blades radially and evenly arranged around the circumference. An annular flow channel is formed between the pump body and the impeller, and both the suction port and the discharge port are at the outer circumference of the impeller. There is a partition between the suction port and the discharge port, thereby separating the suction port and the discharge port.
