The invention discloses a roasting furnace for industrial waste salt treatment and a treatment method. The roasting furnace is a vertical indirect heating roasting furnace and is assembled by three sections including a bottom discharging cone body, a middle roasting furnace cylinder body and an upper feeding mechanism, a pyrolysis cavity used for roasting pyrolysis of industrial waste salt and a closed cavity used for allowing a hot air flow of a burner to flow are formed in the roasting furnace cylinder body, and parts, making contact with the high-temperature salt, in the roasting furnace are all provided with protection layers resistant to high-temperature chlorine salt corrosion. The roasting furnace equipment can achieve roasting recycling of the industrial waste salt, and equipment corrosion and secondary pollution problems during waste salt pyrolysis roasting are solved.
Description
technical field [0001] The invention belongs to the field of solid waste and hazardous waste treatment, in particular to equipment and methods for recycling industrial waste salt. Background technique [0002] Many production processes produce a large amount of waste salt containing organic matter. For example, a large amount of waste salt will be generated at the end of the production of phenol acetone, formic acid, vitamin C, etc.; the organic matter in the total dissolved solids of the waste salt produced by vitamins accounts for nearly 30%. A lot of waste salt has been included in the national hazardous waste list, and with the development of important fine chemicals and intermediate products, the output of waste salt continues to increase. Because waste salt contains harmful substances, it cannot be directly used as industrial raw materials, and its disposal is difficult and expensive. Many enterprises continue to build warehouses for storage, occupying a large amount o...
