Incinerator of multi-element multi-dimension chemical hazardous waste

Abstract

The invention discloses an incinerator of multi-element multi-dimension chemical hazardous waste. The incinerator comprises an auxiliary fuel feeding device, a tilting-type reciprocating grate, a primary air system, a secondary air system, a tertiary air system, a lower part grate combustion chamber, an upper part furnace combustion chamber, a waste liquid nozzle, a waste gas nozzle, a solid waste throw-in mouth, a secondary auxiliary combustion system and a slag removing device; the incinerator is provided with a high-temperature fire bed and a larger furnace chamber space; and after the waste is thrown into the incinerator, the waste can be combusted in the furnace through preheating and decomposition, the combustion is rapid and thorough, and poisonous substances in the chemical hazardous waste can be removed effectively. The incinerator provided by the invention has the advantages of simple manufacturing process and is safe and stable in operation, is convenient to maintain, can burn waste gas, waste liquid, solid waste and the like simultaneously, and is suitable for popularizing and using in the burning treatment of the multi-element waste.

Description

technical field [0001] The invention belongs to the technical field of waste incinerators, in particular to chemical hazardous waste incinerators. Background technique [0002] The high-risk waste gas, waste residue and high-salt (mainly alkali metal salts) organic waste liquid produced by petrochemical, pharmaceutical, pesticide and dye industries will endanger human health and cause pollution to the natural environment. Harmless, reduction and resourceful treatment. However, due to the high salt content and high toxicity of these wastes, they can hardly be treated by biochemical methods. [0003] In the prior art, auxiliary fuel incineration is widely used to treat such high-salt and highly toxic wastes. The deficiencies of the prior art are: wastes of different forms are treated with different incinerators, and the incinerator has a single purpose; the treatment of waste liquid is directly incinerated in the incinerator, and the treatment cost is high; the high-temperat...

AI Technical Summary

Problems solved by technology

The deficiencies of the prior art are: wastes of different forms are treated with different incinerators, and the incinerator has a single purpose; the treatment of waste liquid is directly incinerated in the incinerator, and the treatment cost is high; the high-temperature smoke produced in the incineration treatment The gas contains a large amount of alkali metal salts with low melting points. These substances have a strong corrosive effect on the furnace lining and heat exchange surface, often causing the furnace lining to be burned out or the heating surface to be fouled and blocked, so that the entire treatment system cannot operate normally.
