Embodiment 1

[0096] A method for processing furnace ash and slag using the above-mentioned plasma incineration and melting system for processing furnace ash and slag, the steps are as follows:

[0097] ⑴ Place the above-mentioned plasma incineration and melting system for processing furnace ash and slag at the tail of the original rotary kiln system, so that the feed end of the slag bin is connected to the slag discharge point at the tail of the original rotary kiln system, and the processed The slag is collected into the slag silo through the dust collector;

[0098] ⑵Convey the ash collected by the dust collector to the ash silo through the screw feeder;

[0099] (3) Put the additives in the additive silo, and then transport the materials in the slag silo, ash silo, and additive silo to the mixing device through the slag feeding device, furnace ash feeding device, and additive feeding device in turn. , mixed by a mixing device;

[0100] Among them, the amount of furnace ash added is no...

Embodiment 2

[0110] A method for processing furnace ash and slag using the plasma incineration and melting system for processing furnace ash and slag as described above, the steps are as follows:

[0111] (1) The plasma incineration and melting system is located at the tail of the rotary kiln, where the slag is discharged. The slag processed by the rotary kiln is collected into the slag bin. The slag feeding device adopts the spiral feeding method. The feeding device is wear-resistant and anti-corrosion. The equipment is made of wear-resistant stainless steel. The feeding device is equipped with a weighing scale to measure the feeding dose.

Abstract

The invention relates to a plasma incinerating and melting system for disposing furnace ash and furnace slag. The plasma incinerating and melting system comprises a dust catcher, a furnace slag stock bin, a furnace ash stock bin, an additive stock bin, a furnace slag feeding device, a furnace ash feeding device, an additive feeding device, a mixing device, a lifting device, a feeding stock bin, a spiral conveyor, a plasma incineration furnace, a water quenching machine, a glass body material box, a compressor and an air storage tank. The plasma incinerating and melting system can perform harmless and recycling treatment on the furnace ash and the furnace slag of a hazardous waste incinerator, and the furnace ash and the furnace slag, which are hazardous waste products, at the tail part of a hazardous waste treatment rotary kiln form nontoxic and harmless glass bodies which can serve as construction and building materials to be recycled, so that resources are saved, and environmental protection is facilitated. Therefore, the plasma incinerating and melting system can be widely applied to harmless and recycling treatment of furnace slag and fly ash at the tail part of the rotary kiln, and can realize whole-course automatic control.

Description

technical field [0001] The invention belongs to the technical field of environmental protection, and relates to a rotary kiln system for hazardous waste disposal, in particular to a plasma incineration melting system for processing furnace ash and slag and a method for processing furnace ash and slag by using the system. The system is a rotary kiln for disposal Produced furnace ash and slag to harmless equipment. Background technique [0002] As we all know, solid hazardous waste has many harmful characteristics such as toxicity, explosiveness, corrosion, chemical reactivity, infectivity, radioactivity, etc., which cause serious pollution to the environment, and the impact time is long, causing serious damage to the sustainable development of the environment and economy. hazards. According to statistics, the global solid hazardous waste discharge is about 330 million tons per year. The environmental hazards and survival impacts of solid hazardous waste on human beings canno...
