Lime kiln and lime producing system

Abstract

The invention relates to the technical field of furnace kiln equipment, in particular to a lime kiln and a lime producing system. The lime kiln comprises a kiln, a plurality of layers of preheating zones and a calcining zone. The preheating zones are arranged in the kiln and are provided with first separation walls, first support plates and first air capped pipes. The lime producing system comprises a central controller, sensors and the lime kiln. Compared with the prior art, the lime kiln and the lime producing system have the advantages that raw materials can be scattered on the first support plate in the preheating zone on the uppermost layer to be preheated and are suspended in the air, the raw materials which conform to particle size requirements can be blown by hot air to cross the first separation walls and flow into the preheating zones of the corresponding next layers and can be preheated by the multiple layers, accordingly, preheating effects can be effectively improved, half-baked phenomena of the raw materials when the raw materials are calcined in the calcining zone can be prevented, and the quality of products can be improved; the raw materials only need to be fed from a feed inlet, can be conveyed to the calcining zone via the preheating zones and then can be discharged, accordingly, the lime kiln and the lime producing system are convenient and speedy, the production efficiency can be improved, and the lime kiln and the lime producing system can be continuously operated.

Description

technical field [0001] The invention relates to the technical field of kiln equipment, in particular, to a lime kiln and a lime production system. Background technique [0002] Lime kiln is a kiln used to calcine limestone and decompose limestone into quicklime and carbon dioxide under high temperature conditions. Quicklime is a common desiccant used to remove water vapor by chemical absorption. It is also used in iron and steel, pesticides, medicines, desiccants, tanning and alcohol dehydration. It is especially suitable for puffed food, shiitake mushrooms, fungus and other local products, as well as products in instrumentation, medicine, clothing, electronic telecommunications, leather, textiles and other industries. [0003] However, in the existing production process of preparing quicklime, it is necessary to put limestone and fuel into the lime kiln for preheating and start to decompose at 850 degrees, complete calcination at 1200 degrees, and then after cooling, unloa...
