Project Introduction: With the promulgation and implementation of the new 'Atmospheric Pollutant Emission Standards', the dust emission concentration from coal-fired boilers must comply with a standard of C0≤30mg/Nm3, and in key areas, the standard is even stricter at C0≤20mg/Nm3. Common electrostatic precipitator technologies are difficult to meet these requirements. Bagged dust collectors, due to their high investment and maintenance costs, are also not the best option. 成果优势: Wet phase change meets high-efficiency PM2.5 removal technology and equipment work by condensing phase change, liquefying the saturated flue gas at the outlet of the desulfurization tower. During liquefaction, the droplets capture micron and submicron-sized pollutant particles. The gas-liquid separation is then achieved through a multi-pipe separator. Inside the multi-pipe separator, direct current high voltage electricity is input, causing the corona electrode wires to continuously emit electrons, ionizing the gas between the electrodes into positive and negative ions. Dust, acid mist, and other particles become charged when they come into contact with the electrons. This process can effectively remove liquid or solid particles with diameters of 0.1 to 20μm from the airflow, while also removing some gaseous pollutants (such as SO3) and a large amount of moisture. It has advantages such as high collection efficiency, less pit corrosion, low resistance, simple structure, convenient operation and maintenance, and is capable of handling high-temperature, high-humidity airflows. This technology consumes less electricity and water than conventional wet electrostatic precipitators, and achieves higher dust removal efficiency. Application fields: Mainly used for coal-fired boilers, metallurgy, chemical industry, cement, etc., in the transformation of dust emissions to meet standards.
