Problems solved by technology

However, at this stage, sodium chloride has been oversupplied, causing the by-product sodium chloride of many chemical companies to become solid waste, which has been piled up or landfilled for a long time, covering a large area and causing salinization of the land, resulting in great pollution and waste of resources

Abstract

The invention discloses a kiln and method for converting chemical engineering hazardous waste sodium chloride into refined industrial salt. The kiln comprises a kiln body and two independent dioxin removing chambers. The two dioxin removing chambers each communicate with a melting tank of the kiln body through a small furnace. Each small furnace is provided with a first flame projector. A second flame projector is arranged on the side wall of each dioxin removing chamber. Each dioxin removing chamber communicates with a main flue through a smoke discharging pipe. The two smoke discharging pipes are each internally provided with a flue gate. Two combustion supporting devices supply combustion supporting air into the corresponding dioxin removing chambers alternately. After being preheated through the dioxin removing chambers, the combustion supporting air enters the melting tank through the small furnaces. The melting tank is designed to resist to seepage, and by means of the melting tank, a byproduct, namely the sodium chloride, can be converted into the refined industrial salt; the purpose that hazardous waste is treated in a factory is achieved; high-temperature flue gas generated by the melting tank enters the dioxin removing chambers through the small furnaces, and the temperature is raised to 1200 DEG C or above, so that dioxin is removed; and secondary pollution is not caused.

Description

technical field [0001] The invention relates to the field of recycling chemical waste hazardous sodium chloride, in particular to a kiln and method for converting chemical waste hazardous sodium chloride into refined industrial salt. Background technique [0002] Sodium chloride is widely used in industrial fields such as dyes and pharmaceutical synthesis. However, at this stage, sodium chloride has been oversupplied, causing the by-product sodium chloride of many chemical companies to become solid waste, which has been piled up or landfilled for a long time, covering a large area and causing salinization of the land, resulting in great pollution and Waste of resources. How to effectively dispose of waste salt without secondary pollution and realize the comprehensive utilization of resources has always been an urgent problem to be solved by those skilled in the art. Contents of the invention [0003] The object of the present invention is to address the corresponding def...
