The Research Of Gas-Solid Suspension Flow Filtration Concentration Technology

This topic research aim to pretreatment the flue gas, namely, in virtue of the fly ash inspissation equipment to separate one part of gas (its concentration of the dust contented national emmision standard) from the flue gas and release directly, Lower the handing capacity of the electrostatic precipitators, raise the dust efficiency, making it can attain the national standard. This topic adopt suspension flow filtration concentration technique, PTFE membrane filter material is the research object. PTFE membrane filter material is one kind of filter media ,which is far more tiny opening,very glossy,detest water PTFE filter membrane together composite with distinct foundation materials(such as the needle felt and textile fabric). This paper carries on an overall analytical evaluation to the resistance characteristic of PTFE membrane filter media, studying the relationship of"filtration velocity-filtration resistance"under the condition of the pure air current and the dust air current, In the abstract, make the preliminary discuss, establish the mathematics model of circulated resistance, then through the experiment to verify the above-mentioned model, it fits together mutually as a result.
