Waste salt harmless treatment system and process

The invention provides a waste salt harmless treatment system and process, and relates to the technical field of waste salt treatment. A harmless treatment system for waste salt comprises a primary treatment mechanism, an oxygen-enriched melting furnace in butt joint with the primary treatment mechanism, a waste heat recovery mechanism in butt joint with the primary treatment mechanism and used for receiving tail gas, and a material collection mechanism in butt joint with the oxygen-enriched melting furnace. Waste salt can be put into the initial treatment mechanism, the initial treatment mechanism is obliquely arranged, ton bag materials and irregular materials can be conveniently received, waste materials can be gradually heated, then the heated waste salt is input into the oxygen-enriched melting furnace to be decomposed and melted, organic matter is eliminated, the oxygen-enriched melting furnace treats the waste salt in an oxygen-enriched side-blowing mode, fuel can be fully combusted, and the energy con
