Living Garbage Pyrolysis Gas Purification Equipment Research And Application

Traditional living garbage processing technology includes landfill, composting andincineration, etc. In recent years, Living garbage was disposed by using the pyrolysismethod because of its less emissions, low content of dioxins in the flue gas, and theadvantages of capacity reduction effect is good, Gradually become one of the importantmethods of the popularization and application of the domestic garbage treatment. Thisarticle through to the pyrolysis gas field test and detailed analysis, Developed a set of atthe same time, realize the coordinated control of pyrolysis of many pollutants in flue gasdust removal integration of deodorization device, And the kg/d in800~800kg/d livinggarbage the industrial test on the pyrolysis furnace, Main conclusions are as follows:（1）Purificationequipment structure designand the selection: The design height is3m, dust collecting plate covers area is3.6m2, choose round tooth line as a dischargeelectrode wire and take with polar distance of210mm; choose three phase high-voltageDC pulse power supply for power and supply of soot blow "grey".（2）Living garbage pyrolysis gas entrance dust concentrationrange is154mg/m~3~667mg/m~3, air volume range is344m~3/h~730m~3/h, Flue gas temperature is65℃,Under the rated operating voltage42kv, Outlet dust concentration is below30mg/m~3,and with the increase of voltage, concentration of export gradually reduce. Under thevoltage of44kv, outlet dust concentration were under10mg/m~3.(3) By a three-phase watt-hour meter calculates the whole purification equipmentrun time energy consumption under42kv voltage， Energy consumption according todeal with garbage is about0.072kw·h/kg; According to the smoke gas meter, Energy consumption is about0.005kw h/m~3。After purification, satisfy the current "standard ofliving garbage burning pollution control" emissions requirements, its peculiar smellbasically eliminated.
