Plasma preheating and cracking integrated system for continuously treating waste salt

Abstract

The invention aims to provide a plasma preheating and cracking integrated system for continuously treating waste salt. The plasma preheating and cracking integrated system is used for fully incinerating and cracking industrial waste salt. The plasma preheating and cracking integrated system comprises a plasma incineration cracking furnace, a collecting hopper and a large-inclination-angle belt conveyor, wherein the plasma incineration cracking furnace comprises a furnace body which is transversely distributed; a feeding screw capable of stirring and pushing materials is arranged in the furnace body in the length direction of the furnace body; a preheating hopper and a plurality of plasma generators are arranged above the feeding screw in the furnace body; all the plasma generators are positioned on the rear side of the preheating hopper; a stirring shaft capable of rotatably stirring materials is arranged in the preheating hopper; a feeding hopper which communicates with the preheating hopper is arranged on the outer wall of the top of the furnace body; a discharging door is arranged on the rear side wall of the furnace body; a feeding hole of the large-inclination-angle belt conveyor communicates with the collecting hopper; and a discharging hole of the large-inclination-angle belt conveyor communicates with the feeding hopper.

Description

technical field [0001] The invention relates to the field of hazardous waste treatment, in particular to a plasma preheating and cracking integrated system for continuous treatment of waste salt. Background technique [0002] Industrial waste salt refers to various waste residues, dust and other wastes discharged during industrial production. In the industrial field, many enterprises produce waste salt in the production process. For example, in the production process of organic and inorganic chemical products, a large amount of mixed waste salt containing salty organic matter is produced. The crystallized salt contains a large amount of organic or inorganic impurities and cannot be used as industrial raw material salt. If it is stacked for a long time, it will take up a lot of space and cause serious pollution and damage to the ecological environment. [0003] At present, the resource conversion of industrial waste salt is generally adopted: one is chemical method, and the...

Problems solved by technology

Although there are plasma incineration and cracking furnaces for waste salt treatment, when dealing with waste salt, it is necessary to put the waste salt into the preheating hopper for heating and stirring, and then enter the plasma incineration and cracking furnace for incineration and cracking. However, the preheating hopper is split, not only separate Occupies an area and needs to use an extra heat source for heating, which is very inconvenient
