Technical Field

The invention belongs to the field of combustion hot melting furnaces, and particularly relates to a high-concentration oxygen cyclone combustion liquid melting treatment system.

Background

Some processes require melting the material to a liquid state and then rapidly quenching the liquid material in order to maintain the material in a non-crystalline glassy state with high chemical reactivity. For example, sintering is required for the recovery of alumina and alkali during red mud disposal. The traditional sintering process for alumina production uses a rotary kiln, the temperature of the kiln is about 1250 ℃, and a small amount of melting is maintained. However, unlike sintered bauxite, red mud often contains a lot of iron oxide, and the melting point of the eutectic substance generated by the red mud, calcium oxide, silicon oxide and sodium oxide is only 1100 ℃, so that the main components in the rotary kiln are not completely reacted, a large amount of agglomerates are formed in the rotary kiln, and the rotary kiln cannot normally operate. In addition, in the rotary kiln, the components are in solid-solid contact, and although the components are ground into fine powder, the reaction time is still long. If the melting-cold quenching treatment of the liquid melting furnace is adopted, only calcium needs to be added for quick melting and cold quenching, and the alumina and the alkali in the treated material can be recycled by high dissolution rate; for example, the tailings of the red mud after alkali and alumina are recovered contain calcium, silicon and aluminum oxides as main components, and the calcium, silicon and aluminum oxides exist in the forms of calcium silicate hydrate and calcium aluminate hydrate and lose chemical reaction activity. The modification method is to melt the mixture into liquid and then rapidly cool and quench the liquid. The same is true of the way of increasing the activity of fly ash and the like. More than 1 hundred million tons of red mud are generated every year in China, and because the components are mutually restricted, the red mud can be only utilized in a low-value mode by 4 percent, and the modification has important practical significance for high-value utilization. The fly ash in developed areas is utilized, but China has coal main producing areas, namely jin, shan, Mongolia and Qian, far away from the developed areas, is still difficult to utilize if the coal main producing areas cannot be converted into high-value products to be transported out, and has important practical significance for high-value utilization of the coal main producing areas through modification.

However, the existing liquid melting furnace has the problems of low recovery rate of high-temperature flue gas waste heat, high fuel consumption of unit materials and high difficulty in emission standard reaching caused by the generation of a large amount of nitrogen oxides. Therefore, the liquid melting furnace suitable for materials such as red mud and fly ash needs to be researched.
