Lithium carbonate acidification kiln is an important industrial equipment used to produce inorganic salt products such as lithium carbonate. In the lithium carbonate acidification kiln, the raw material undergoes a series of chemical reactions and physical changes and is finally converted into products such as lithium carbonate. This article will introduce the principle, structure, operation and maintenance of lithium carbonate kiln, and help readers better understand and master the relevant technology and experience of lithium carbonate kiln.
1. The principle of lithium carbonate acidification kiln.
The principle of lithium carbonate acidification kiln is mainly based on the reaction of calcium, magnesium, silicon and other raw materials with sulfuric acid to generate corresponding sulfate and sulfur dioxide and other gases. At high temperatures, these sulfates oxidize with the oxygen in the kiln to produce gases such as oxides and sulfur trioxide. At the same time, the materials in the kiln will also undergo some physical changes, such as solid-phase reaction, melting and solidification. Eventually, these reaction products undergo cooling, crystallization, and separation processes to obtain inorganic salt products such as lithium carbonate.
Second, the structure of lithium carbonate acidification kiln.
The lithium carbonate acidification kiln is usually composed of the kiln body, feeding system, combustion system, smoke exhaust system, cooling system, crystallization and separation system. Among them, the kiln body is the core part of the entire production process, and its design and manufacturing quality directly affects the quality and yield of lithium carbonate products. The function of the feeding system is to continuously feed the raw materials into the kiln to ensure the continuity of production. The combustion system provides the necessary heat in the kiln so that the raw materials can fully react. The smoke exhaust system discharges the flue gas generated during the reaction process to prevent environmental pollution. The function of the cooling system is to quickly cool the reaction products and prevent the product from decomposing. The crystallization and separation system separates the product from other reaction products to obtain lithium carbonate with higher purity.
3. Operation and maintenance of lithium carbonate acidification kiln.
When operating and maintaining a lithium carbonate acidification kiln, the following points need to be noted:
1.The ratio and quality of raw materials have an important impact on the quality and yield of lithium carbonate products, so the proportion and quality of raw materials should be strictly controlled.
2.During the production process, the temperature and pressure in the kiln should be kept stable to ensure the smooth progress of the reaction.
3.Regularly inspect and repair the equipment to ensure the normal operation and service life of the equipment.
4.For the emitted flue gas, it is necessary to treat and purify it to prevent environmental pollution.
5.In the production process, it is necessary to pay attention to safety issues, such as preventing high temperature scalding, corrosion, etc.
Fourth, the future development of lithium carbonate acidification kiln.
With the progress of science and technology and the development of society, lithium carbonate acidification kiln is also developing and improving. In the future, lithium carbonate acidification kilns will be more efficient, environmentally friendly and intelligent. For example, new combustion technologies and materials are used to improve combustion efficiency and product quality; Intelligent control technology is used to realize the automation and intellectualization of the production process; Strengthen environmental protection measures and reduce pollutant emissions.
In short, as an important inorganic salt production equipment, the knowledge of the principle, structure, operation and maintenance of lithium carbonate acidification kiln is indispensable for relevant practitioners. In the future, with the continuous progress of technology and the continuous expansion of application fields, lithium carbonate acidification kiln will play a more important role.
