Device for curing heavy metals by means of high-temperature sintering charcoal

Abstract

The invention discloses a device for curing heavy metals by means of high-temperature sintering charcoal. The device is composed of a hot smelting kiln furnace, a feeding device, a chain row fire barsystem, a quenching water pool and a high slagging conveyor. Industrial hazardous wastes are spirally fed into the chain row fire bar system in the hot smelting kiln furnace through the feeding equipment, move slowly in the hearth of the hot smelting kiln furnace, and are incinerated at high temperatures by combustors arranged on two sides of the hot smelting kiln furnace, so that formation of pyrolytic dioxin molecules is destroyed and a stable inorganic compound is formed by reaction of heavy metals in the high-temperature state and mixed carbon element, and therefore, pollution diffusion ofthe industrial hazardous wastes is avoided. Incinerated tail gas is connected to a flue gas disposal system through a flue gas outlet, and mixing slag falls into the conveyor in the water pool belowthe hot smelting kiln furnace and is discharged after being cooled by water.

Description

technical field [0001] The invention relates to the fields of solid waste environmental protection disposal, mechanical automation and the like, in particular to high-temperature sintered carbon solidification heavy metal equipment. Background technique [0002] With the continuous advancement of my country's industrialization process, the discharge of industrial hazardous waste in the process of industrial production has increased sharply. Industrial hazardous waste generally refers to industrial production discharges with hazardous characteristics such as corrosiveness, toxicity, flammability, reactivity, and infectivity, which are extremely harmful to water, air, soil, and human health. Since the leakage of industrial hazardous waste during transportation can easily lead to secondary pollution, and the discharge of hazardous waste from production sites in industries such as thermal power, mining, and gas extraction is huge, effective methods are needed for on-site harmles...

AI Technical Summary

Problems solved by technology

[0004] 1. There is no carbon solidification treatment step in the heat treatment process, so the heavy metals contained in hazardous waste cannot be removed, and discharge into the environment will cause secondary pollution;

[0005] 2. The space placement of the internal mechanism of the equipment is unreasonable, the processing process is not continuous, and the processing capacity of the equipment is low
