Abraum salt high-temperature melting oxygen blowing kiln

Abstract

The invention discloses an abraum salt high-temperature melting oxygen blowing kiln. The kiln comprises a kiln body, an oxygen blowing pipe, a transition segment and an air supply opening; the kiln body is of a horizontal structure, a feeding opening and a slag discharging opening are formed in the kiln body, a smoke staying chamber is formed in the upper portion of the kiln body, a flame path isarranged in the middle, a molten pool is arranged on the lower portion, a kiln ridge is arranged in the middle of the molten pool, the transition segment is arranged in an inclined upward manner, an inlet of the transition segment communicates with the smoke staying chamber, air needed by abraum salt combustion enters the kiln body from the air supply opening, and the oxygen blowing pipe leads tothe molten salt in the molten pool. The engineering problem appearing during high temperature incineration process adopted in the abraum salt solid waste is solved, frequent blowing out caused by short running time of medical and chemical enterprises can be avoided, losses of long-period cleaning caused by heating face corrosion by abraum salt are reduced, utilizability after high-temperature incineration of salt containing hazardous waste can be improved, and harmless, reduction and resource aims of the salt containing solid waste are finally achieved.

Description

technical field [0001] The invention relates to the technical field of salt-containing solid waste incineration, in particular to a high-temperature melting oxygen blowing kiln for waste salt. Background technique [0002] At present, many enterprises will generate a large amount of salt-containing solid waste in the production process. The market demand for the disposal of salt-containing solid waste is huge. Many chemical or synthetic pharmaceutical enterprises have stopped production due to their inability to properly dispose of salt-containing solid waste. At the same time, the solid salt is often treated as solid waste because the organic matter in it cannot be reused in industrial production, which wastes resources and costs a lot. [0003] Compared with comprehensive utilization and safe landfill technology, high-temperature incineration can more effectively destroy harmful substances in salt-containing hazardous waste. During incineration, hazardous salt-containing ...

AI Technical Summary

Problems solved by technology

[0009] The invention solves the engineering problems that occur when high-temperature incineration technology is used for salt-containing solid waste, improves the current situation of frequent shutdowns in pharmaceutical and chemical enterprises due to short running time, reduces the loss of long-term cleaning caused by waste salt corrosion on the heating surface, and improves The availability of salt-containing hazardous waste after high-temperature incineration finally realizes the harmlessness, reduction and recycling of salt-containing solid waste, and provides a waste salt high-temperature melting oxygen blowing kiln
