Description

Technical Field

[0001] The utility model relates to the technical field of high-calcium ash production, in particular to an air supply device used in the calcining process of high-calcium ash. Background Art

[0002] High calcium ash refers to fly ash with a CaO content higher than 10%. The production process is to add screened limestone and fuel into the kiln from the top of the kiln at a regular and quantitative rate, calcine at 900-1200°C, and then cool to obtain the finished product. The top of the lime kiln is the preheating section, the middle is the combustion section, and the bottom is the cooling section.

[0003] After searching, the Chinese patent publication number is CN213578773U, and the publication date is 2021-06-29. It discloses a lime kiln air intake system, which relates to the technical field of producing quicklime, including a lime kiln, an air intake assembly and a cooling assembly. The lime kiln includes a kiln body and a combustion chamber, an air supply chamber and an air suction chamber distributed on the kiln body from top to bottom. The air intake assembly includes a blower, a preheating pipe 1 and a preheating pipe 2. The blower is connected to an air guide pipe 1, and the air guide pipe 1 is connected to two air guide pipes 2. The upper and lower air guide pipes 2 are respectively connected to the combustion chamber and the air supply chamber. The preheating pipe 1 and the preheating pipe 2 are both spiral structures and are respectively mounted on the upper and lower air guide pipes 2. The cooling assembly includes an air cooling pipe 1, an air cooling pipe 2, a cooling pipe and a filter bag. The two air cooling pipes are respectively connected to the two preheating pipes. The air cooling pipe 1 and the air cooling pipe 2 are both connected to a cooling pipe. The cooling plates are evenly distributed inside the cooling pipe, and the filter bag is installed at the air outlet end of the cooling pipe. The lime kiln air inlet system in the present application has the characteristics of reasonable structural design and low implementation and operation cost. However, the finished product after calcination is discharged from the bottom of the cooling section. The wind hood that controls the uniformity of air supply is located in the cooling section and is easily blocked by powder, which causes the air inlet system to malfunction and affect the calcination effect. It also causes damage to the Roots blower. In addition, the spiral structure in the system is prone to smoke and particulate accumulation during the smoke exhaust process, which hinders smoke exhaust and further affects the entire air inlet system and is difficult to clean.
