Embodiment Construction
[0007] As shown in the figure, first make limestone of different sizes into 0.5-1cm particles, crush white coal or coke into powder, then put the limestone particles into the mixer, spray mist in the mixer, and at the same time Mix white coal or coke powder into the mixer, when the limestone particles are coated with a layer of white coal or coke powder, send it to the top of the kiln, and pour it into the kiln through the distributor, the highest temperature layer in the kiln The temperature is 1100°C±100°C, the fan supplies air to the kiln from the bottom, and the active lime leaks out from the bottom of the kiln.

The active lime producing process includes coating limestone in certain size with one layer of fuel powder, and calcining while ventilating. The said process can calcine limestone completely to produce homogeneous active lime of high quality in high yield and low power consumption.
Description
1. Technical field: [0001] The invention relates to a production method for producing active lime. 2. Background technology: [0002] In the traditional production of active lime, generally large and small limestones are transported to the silo, mainly larger pieces, and then the limestone in the silo is put into the burning kiln for calcination. Gradually take out the ash. This traditional method has many deficiencies: first, the quality of the finished ash is poor, and the second is that it requires a lot of fuel, that is, the output of ash per ton of fuel is low; third, the output is low. 3. Contents of the invention: [0003] The invention aims to solve the problems of low product activity, low ash yield per ton of fuel and low output of traditionally produced active lime. [0004] The technical scheme adopted by the present invention in order to solve the above problems is: use 0.5-1cm limestone as raw material, pulverize white coal or coke into powder, put 0.5-1cm ...
