Basic performance comparison bag filter and electrostatic filter bag III

Investment in equipment As a user, is most concerned about is the dust of investment issues, the following make a comparison for the two kinds of dust under different conditions of investment: 1, the conventional smoke and dust conditions (mainly refers to the more suitable electrostatic bag house smoke) both dust emission concentration to reach the current low environmental requirements (such as 150mg / m³) than the initial investment bag house about 20-35 high electrostatic bag house 2, for low-sulfur high-resistivity dust, high SIO2, AL2O3 class is not suitable for electrostatic bag house dust collecting both dust to reach the current low environmental requirements (such as 150mg / m3) the initial investment electrostatic bag house and bag relatively high electrostatic bag house dust or invest more. 3, under normal conditions to achieve the same removal efficiency or to achieve the same emission concentration, high investment investment is usually better than the electrostatic bag house bag filter. In Hohhot Power Plant 200MW machine-level example: Bag filter: Dust investment each unit <20 million yuan to ensure the emission concentration <50mg / Nm³ or less. Electrostatic precipitators: four-field calculation than dust collection area 130m² / m³ / S. Status 250mg / Nm³, each divider investment of about 25 million yuan.
