Embodiment 1

[0049] The following is an example of using the above-mentioned solid and liquid hazardous waste plasma cracking and vitrification treatment equipment and methods to treat common oilfield sludge in solid hazardous waste. The specific treatment process is as follows:

[0050] 1. First turn on the plasma incineration cracking furnace and vitrification melting furnace to preheat the inside of the furnace;

[0051] 2. 160 tons of oil sludge to be treated will be evenly transported to five groups of 120 plasma incineration and cracking furnaces for incineration and cracking within 20 hours after passing through the preheated hopper. The incineration temperature is controlled between 600-1000 degrees Celsius. The plasma generators and material propulsion components in each unit furnace body start to work, and the oil sludge is incinerated and cracked through each unit furnace body in turn, and the materials are stirred at the same time, so that the oil sludge can be continuously tran...

Embodiment 2

[0055] The following is an example of using the above-mentioned solid and liquid hazardous waste plasma cracking and vitrification treatment equipment and methods to treat common garbage concentrates in liquid hazardous waste. The specific treatment process is as follows:

[0056] 1. First turn on the plasma incineration cracking furnace and vitrification melting furnace to preheat the inside of the furnace;

[0057] 2. 120 tons of landfill leachate to be treated (with a moisture content of about 98%) will be uniformly transported to the hearth of three groups of 90-section plasma incineration and cracking furnaces for 1 hour of incineration after passing through the preheated hopper within 20 hours Cracking, incineration temperature is controlled between 600-800 degrees Celsius, the plasma generators and material propulsion components in each unit furnace start to work, fully stirred, so that the concentrated solution is continuously and fully cracked to form ash, and the weig...

Embodiment 3

[0061] The above-mentioned solid and liquid hazardous waste plasma cracking and vitrification treatment equipment and methods can be used to treat fly ash and can also achieve good results. The specific treatment process is as follows:

[0062] 1. First turn on the plasma incineration cracking furnace and vitrification melting furnace to preheat the inside of the furnace;

[0063] 2. 120 tons of fly ash to be processed will be evenly transported to the hearth of the 20-section plasma incineration cracking furnace within 20 hours after being preheated to the furnace for 10 minutes of incineration. The incineration temperature is controlled between 850-1000 degrees Celsius , remove the dioxins in the fly ash and heat the fly ash;

[0064] 3. The fly ash incinerated by the plasma incineration cracking furnace is transported by the screw conveyor to the vitrification melting furnace for 40 minutes of incineration. The incineration temperature is controlled between 1600-1800 ° C, a...

Abstract

The invention aims to provide solid and liquid hazardous waste plasma cracking and vitrification disposal equipment and a solid and liquid hazardous waste plasma cracking and vitrification disposal method, wherein a glass body is hung to a wall to block and scrap and the work efficiency is high. The equipment comprises a plasma incineration cracking furnace for pre-treating reduction of hazardouswaste and a vitrification melting furnace which vitrifies the reduced ash. A discharge port of the plasma incineration cracking furnace communicates to a feed inlet of the vitrification melting furnace. Reduction and vitrification are carried out successively.

Description

technical field [0001] The invention relates to the field of hazardous waste treatment, in particular to a plasma cracking and vitrification treatment equipment and method for solid and liquid hazardous waste. Background technique [0002] Hazardous waste is solid and liquid waste that has one or more hazardous characteristics (such as corrosive, toxic, flammable, reactive, and infectious) and is harmful to the environment or human body and needs to be treated as hazardous. There are many types and sources of hazardous waste, and the treatment is extremely difficult, especially the complete and harmless treatment is even more difficult. With the improvement of environmental protection regulations and standards, the disposal standards of hazardous waste are more stringent, and the society is also exploring new and revolutionary treatment processes to ensure the true realization of harmless disposal and fill the gaps in the industry's treatment processes and methods. [0003]...
