Widely Used LECA Rotary Kiln Large Capacity Highly Efficient Long Service Life
LECA Rotary Kiln Introduction:
LECA (Light Expanded Clay Aggregate) as a new environmental protection material is widely used in the construction field. It can be made of wallboard, brick and other new wallboard material. It also can be used for insulation, floor, lightweight concrete, water treatment and etc. LECA Rotary kiln is the key equipment in the LECA production. The performance will effect the final LECA quality and production cost directly.
Before building ceramsite production line, we should first understand the local environmental protection requirements for kiln emissions, focusing on the emission standards for dust content, nitrogen oxides, sulfides, and odors. Then, according to local environmental protection standards, exhaust gas treatment system that meets local requirements is designed.
When designing an exhaust gas treatment system, it is necessary to consider the fuel problem, because the components of the exhaust gas are completely different from the burnt rice bran, coal, and natural gas. These must be fully analyzed and understood before construction, and the influence of raw materials, fuels and working conditions on the composition of the flue gas must be fully considered.
Generally, when we deal with the dust of the kiln tail gas, we will use the kiln tail smoke chamber, cyclone dust collector or ceramic multi-tube dust removal, bag dust removal to solve this problem, and then the instability of the working conditions should be considered in the system design. Then design emergency facilities and dust removal and utilization equipment so that the dust can be easily resolved. Then we will consider whether it is out of stock, low temperature or high temperature. The two ways in investment and later stag, the cost is very different. In addition, according to the flue gas composition and flue gas volume, desulfurization and nitrogen oxide removal are appropriately considered to design and select equipment.
Finally, according to whether there is a peculiar smell in the flue gas, choose the corresponding deodorizing device, but the deodorizing equipment on the market is not very durable, and the selection should consider the working conditions.
