Abstract

The invention discloses an industrial slag salt harmless treatment device. A vulcanization dryer is connected with a first spiral conveyor and a first middle tank, and communicates with a first cyclone separator by a first conveying pipe; the top of a temporary storage tank communicates with the vulcanization dryer; a crushing screener is arranged under the temporary storage tank, and communicates with the same; a second middle tank is arranged on one side of a feeding tank, and communicates with a second cyclone separator and a fan in sequence; the bottom of the second cyclone separator communicates with the second middle tank; a third middle tank, a fourth middle tank and a calcining tower are arranged under the second middle tank; the third middle tank and the fourth middle tank respectively communicate with the second middle tank; the bottoms of the third middle tank and the fourth middle tank both communicate with the calcining tower by sixth conveying pipes; the sixth conveying pipes are aslant arranged; and the third middle tank and the fourth middle tank both communicate with the calcining tower by pressure guide pipes. The device is simple in structure and stable and efficient in equipment operation. The invention further discloses an application method of the device.

Description

technical field [0001] The invention relates to the field of environmental protection, in particular to a harmless treatment device for industrial slag salt and a method for using the same. Background technique [0002] In the process of producing hydrazine hydrate, furan phenol, pesticides, intermediates and other products, a large amount of industrial slag salt will be produced. . At present, due to the lack of energy-saving and environmentally friendly treatment methods, this kind of waste is mainly treated by landfill, resulting in waste of resources and environmental pollution. SUMMARY OF THE INVENTION [0003] The technical problem solved by the present invention is to provide a harmless treatment device for industrial slag salt, which can perform harmless treatment of industrial slag salt in batches, the obtained salt particles have high purity, and the treatment process is simple. [0004] In order to solve the above technical problems, the present invention is a...
