What is the process principle of high concentration waste salt disposal

As for the question "Common process methods for the disposal of high concentration industrial waste salt", the high concentration waste salt disposal technology will give you a detailed answer, as follows:

Pyrolysis is the process of chemical decomposition of organic matter into gaseous, liquid or solid flammable substance when it is heated under anaerobic or anoxic conditions. Gaseous products are typically hydrogen, methane, and carbon monoxide, liquid products are typically methanol, tar, and dissolved oil, and solid products are typically coke or carbon black. The pyrolysis process of solid waste is a complex chemical process, including bond breaking of large molecules, isomerization and polymerization of small molecules, etc., to produce a variety of smaller molecules.

There are many factors affecting the pyrolysis products of organic solid waste, such as material characteristics, pyrolysis final temperature, furnace type, material accumulation characteristics, heating method, residence time of each component, etc.

The correlation degree of each influencing factor is as follows: pyrolysis temperature; Material characteristics; Temperature rise rate > material docking mode; Material heating mode. Different temperature distributions also lead to different yields and characteristics of pyrolysis products. Due to the decomposition of hypoxia, the exhaust volume is small, which is conducive to reducing the secondary pollution to the atmospheric environment.

The main difference between high concentration waste salt disposal technology and conventional process is how to remove organic matter in salt crystal nucleus. The conventional technology used in China is to remove organic matter from the surface of industrial salt with hot air. However, due to the crystal structure of salt, even if the salt crystal is cracked quickly by heat, it will only become more small crystal nuclei, and the organic matter inside the crystal cannot be degraded. High concentration salt disposal techniques use pyrolysis furnaces to increase residence time and pyrolysis temperature (use high temperature pyrolysis; 1000 degrees), change the pyrolysis mode, adjust the heating mode, etc. Pyrolysis of organic matter in industrial waste salt to remove organic matter in crystal nucleus.
