Most use environmentally friendly kiln, kiln more polluting earlier been banned, since most of the use of the environmentally friendly kiln, why kiln was purged with it? Lime kiln kiln gas roughly co243%, o2o.2%, co0%, the rest is n2, temperature 85-100 ℃. Kiln gas can be removed by washing manner, kiln gas scrubber provided sufficient water from the top of the ring or coke gas flow and countercurrent flow, wash the dust, lime kiln equipment, and the gas is cooled by 200 ℃ to 20 -40 ℃. Packed tower little resistance. Operation (entrance 0-15, 50-70 mm water column outlet) in the case of a little decompression. The tower because of the carbon dioxide gas dissolved in a little water, the temperature should be lowered from 0.2 to 0.4%. Lime kiln in the production process, in order to achieve high yield, high quality, low consumption of the purpose of achieving energy saving. Lime kiln flue gas components O2 content of 14.96% (the content of the text refers to volume fraction), CO2 gas content of 19.91%, and the ideal of the flue gas components: O22% ~ 4%, CO2 about 30%, the gap is relatively large . If the flue gas oxygen content of 4% of the ideal value, environmental protection lime kiln equipment, according to the existing flue gas oxygen content of 14.96% calculated excess air ratio of 1.8145, the excess air amounted to 1.8145 times the actual amount of smoke . If the CO2 content of the flue gas by calculating the excess air ratio of 0.5067, then the excess air is about 1/2 of the total amount of smoke. Rotary combustion flue gas treatment system of high temperature flue gas in the preheater after heat exchange with the limestone, lime kiln, the temperature dropped to below 260 ℃, by the multi-tube cooler and then into high temperature baghouse, environmental protection lime kiln dust from a high temperature after the fan into the atmosphere through the chimney, flue dust into the atmosphere concentration of less than 30mg / Nm3. In order to meet the pre-modern lime kiln decomposition process requires the production line to ensure reliable operation of process equipment, stable process parameters, to ensure product quality, save energy, improve the operation rate of the production line. Line using advanced technology and control the whole process, increase DCS control PLC control on the basis of the main production line centralized monitoring, operation and decentralized control, control of rotary kiln operating system to improve product quality and reduce consumption. Electronic control equipment to improve reliability and maintainability to achieve the control, monitoring, modernization operations.
