Abstract

The invention provides a secondary calcination purification device for industrial salt slag. The secondary calcination purification device capable of purifying the industrial salt slat, removing organic impurities and realizing recycling of the salt slag, high in purification efficiency and capable of being produced in batch comprises a primary calcinator and a secondary calcinator which is arranged above the primary calcinator, and the first and second calcinators are connected through a temperature control pipe therebetween; a propeller connected with a power unit is arranged in the primary calcinator, and a primary gas mixing chamber is further connected to the primary calcinator and is connected with a natural gas pipeline as well as an air conduit; the temperature control unit is connected with a spiral conveyer; the secondary calcinator is connected with a secondary gas mixing chamber which is connected with the natural gas pipeline as well as the air conduit; a cyclone separator A is connected to the tail end of the secondary calcinator and is connected with a cyclone separator B; the temperature control pipeline is wrapped with a temperature control unit.

Description

technical field [0001] The invention relates to the field of environmental protection, in particular to a secondary calcination purification device for industrial slag salt. 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, and its components mainly include: sodium chloride 80-90%, water 2-8%, toxic organic matter 2-10% . At present, due to the lack of energy-saving and environmentally friendly treatment methods, this kind of waste is mainly disposed of by landfill, resulting in waste of resources and environmental pollution. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a secondary calcination purification device for industrial slag salt, which can purify industrial slag salt, remove organic impurities, and realize recycling of slag salt; the purification efficiency i...
