Recently, the China Environmental Protection Industry Association released the “National Key Environmental Protection Practical Technology Demonstration Project Directory in 2010”. Jinbei Aluminum Corporation’s “4×50 MW Unit Self-constructed Power Plant Combined Dust Collector Renovation Project” is among them. As a new practical technology for improving the quality of the environment, it is required to promote it.

In 2007, in order to further improve dust collection efficiency, Jinbei Aluminum Corporation reformed the electrostatic precipitator in thermal power plants. After a multi-sectoral joint technical demonstration, the electric bag composite dust removal technology was selected. During the renovation, the company's technical staff boldly broke the original design and changed the two electrostatic fields into an electrostatic field. The electric field and the baghouse were arranged in separate warehouses. The new uniform air distribution design greatly improved electrostatic dust removal and bag dust removal. The major shortcomings have become a new model and model for the dust collection of the environmental protection industry.

After more than three years of operation test, the precipitator is stable, reliable and practical. The dust-removing effect has been kept within 50 milligrams per cubic meter. It has successfully passed the approval of the new technology of the National Environmental Protection Industry Association and created an environmentally friendly enterprise for the company. A positive step has been made.
