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, the dust washed off, and the gas is cooled by 200 ℃ to 20-40 ℃. Packed tower little resistance. Operation (entrance 0-15 Gansu kiln construction projects, export 50-70 mm water column) 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, calculated according to the existing flue gas oxygen content of 14.96%, the excess air ratio of 1.8145, the excess air amounted to 1.8145 times the actual amount of smoke. If you press to calculate the CO2 content in the flue gas kiln construction projects in Gansu, the excess air ratio of 0.5067, then the excess air is about 1/2 of the total amount of smoke. Complete technology is mainly characterized Editor: (1) the system is stable, a small amount of maintenance, operation rate; high production efficiency, yield Gansu kiln construction projects, product quality and excellent performance; (2) energy saving systems ① use of exhaust-free grade high efficiency heat exchanger ② sealing the contacts, a world leader in dust collector ③ heat consumption; (3) the host device ① energy efficient vertical preheater, cooler pressure loss is small, the heat exchange efficiency can be forced to accompany the burning kiln ② ; (4) the application of new refractory ① resistant, high temperature, thermal insulation effect is good composite refractory bricks ② high-strength materials; (5) ① resource utilization of high energy use of waste ② arabica grade limestone can make full use of steel Abandoned low calorific value gas; good (6) key equipment quality and excellent performance ① host device designed and manufactured entirely by our company Gansu burnt lime kiln construction projects based on professional requirements, high performance equipment ② national standards, drawing on international manufacturing system, quality assurance; (7) ① high degree of automation in the use of redundant S7-400H systems, DCS system remote I / O control; ② entire line 2-3 people to operate.
