Abstract
The embodiment of the invention discloses an energy-saving and environmental-protection kiln and a lime preparation method. In the embodiment of the invention, the energy-saving and environmental-protection kiln is provided with a ventilation system and a plurality of kiln furnaces, each kiln furnace is provided with a preheating zone, a mixed combustion zone and a calcining zone. Lime is calcined for three times in the three zones, especially in the calcining process of the mixed combustion zone, the goal of energy recycling and secondary utilization and pollutant recovery can be achieved under the action of the ventilation system, thereby not only saving energy, but also improving product quality and yield, simultaneously avoiding the problems of serious pollution, low resource utilization rate, large energy consumption, low yield and low quality in a traditional earth kiln, and especially overcoming the disadvantages of the traditional rotary kiln, such as high construction cost, high maintenance cost, high production cost and high requirements especially on raw coal quality and lime stone material size. The invention truly and scientifically reaches the technical requirement on energy saving and environmental protection and achieves the goals of saving energy, reducing emission, increasing efficiency and developing enterprises with science, which are advocated in China.
Description
technical field [0001] The invention relates to an energy-saving and environment-friendly kiln and a lime preparation method. Background technique [0002] At present, traditional earthen kilns are mostly used to process limestone to obtain lime. During the preparation process, because the earth kiln has no recovery measures, combustible gases and harmful substances are discharged into the atmosphere without treatment, resulting in energy waste and air pollution. [0003] Therefore, an energy-saving and environment-friendly energy-saving and environment-friendly kiln and lime preparation method are needed. Contents of the invention [0004] In view of this, the object of the present invention is to provide an energy-saving and environment-friendly kiln and a lime preparation method. [0005] To achieve the above object, the present invention provides the following technical solutions: [0006] An energy-saving and environment-friendly kiln, including a feeding system, a...
