Hazardous Waste Incineration Plant

The hazardous waste incineration plant mainly treats waste of hazardous substances through incineration and controls the harmful substances that may be released during the treatment process.

Types of hazardous waste

item	description
Waste solvent	These solvents usually contain organic components.‌
Waste oils, oil emulsions and oil mixtures	These wastes are also flammable and suitable for disposal by incineration ‌‌
Waste plastic, rubber and latex waste ‌	These materials burn efficiently during incineration, reducing volume and weight ‌
Hospital waste, pharmaceutical waste, pesticide waste	These wastes contain harmful substances, incineration can effectively reduce its volume and reduce the harm to the environment ‌
Waste fat‌	Fatty waste can be disposed of harmlessly by incineration ‌
Oil refining waste	The waste produced in the oil refining process is suitable for disposal by incineration ‌
Waxy waste	These wastes can be burned efficiently in the incineration process ‌
Phenolic waste and organic waste containing halogen, sulfur, phosphorus, chlorine compounds	These wastes can break down harmful components during incineration
Solid waste or liquid waste contaminated with hazardous chemicals	These wastes can be incinerated to effectively remove harmful substances ‌
Municipal Solid Waste	Municipal solid waste can be disposed of harmlessly by incineration ‌

Hazardous waste incineration process

STEP 1: Feedstock: According to hazardous waste different species and calorific values, the different hazardous waste is put into different storage. Then mix them together according to their moisture content, calorific value, and compatibility. Finally, it is sent to incineration to be burned.
STEP 2:Incineration of waste: The hazardous waste goes through decomposition, drying, burning, and burn out using a rotary kiln (Horizontal cylinder furnace). More than 95% of the waste has been turned into slag. The slag along with the unburned waste enters the rotary kiln to burn. Finally, all of the slag enters the slagging system. In addition, the high-temperature flue gas produced by the combustion in the rotary kiln and grate enters the secondary combustion chamber. The labor ensures that the flue gas temperature generated by incineration is between 850 ° C and 1200 ° C. Because the gas has lots of volatile substances, these substances are usually poisonous. To ensure these substances are completely oxidized and decomposed, O2 is sent into the secondary combustion chamber to ensure the oxidation and decomposition of toxic and harmful substances in the flue gas. Incineration produces the temperature gas that could be used, the gas enters the waste heat boiler. The heat is absorbed by the boiler to produce steam. The stream could be used to generate electricity or to supply other heat users.
STEP 3: Exhaust gas cleaner: The high-temperature gas can make dioxin decompose, but after the high-temperature gas through heat exchange, the gas temperature is reduced to five or six hundred degrees, and dioxins will be synthesized again. To avoid dioxins synthesis, it needs the quench device to reduce the temperature to less than 200° C. In addition, the gas contains a lot of harmful impurities such as dust, acid gas, and heavy metals. The acid gases such as nitrogen oxides, sulfur oxides, and hydrogen chloride are removed by semi-dry lye spray and kilo-alkali neutralizer, finally, the dust is removed by the cloth bag dust collector. The activated coke is purified and discharged to the standard.
STEP 4: Incineration ash disposal: After the hazardous waste is incinerated, the inorganic matter and unburned organic matter are collected from the grate, waste heat boiler, and dust collector. This ash includes the hazardous substance. If it is not dealt with, it could pollute the soil and groundwater. All polluting components in hazardous waste are chemically inert by stable curing to reduce the toxicity of waste.

Hazardous waste incineration equipment

Hazardous waste crusher

It specializes in treating hazardous waste equipment and turns the hazardous waste into smaller particles so that subsequent processing and disposal. Hazardous waste crusher is used in different crushing methods, including ‌dry system, ‌wet system, and semi-wet system. The dry system separates mental and nonmetal by an air rotation sorting system. The wet system sprays water when is crushing. Semi-wet system spray a little water when needed‌ to prevent dust, but do not wash.

Rotary kiln

The waste is mixed evenly along the tilt Angle to the tilt end of the flip state by the whole kiln body rotates. To the waste complete incineration, it set up a secondary combustion chamber. The most hazardous waste is heated by the gas produced during the combustion of the fuel and the heat transferred by the kiln walls. The hazardous waste enters the rotary kiln and receives heat radiation from the auxiliary burner flame and high-temperature kiln wall to finish heating, water evaporation, and flammable precipitation.

Tail gas treatment equipment

The tail gas treatment equipment is used to dispose of the tail gas produced during the pyrolysis process. The tail gas treatment includes absorption equipment, ‌ adsorption equipment, etc. These equipment use different treatments to recycle or remove and reduce the harmful components of exhaust gas such as absorption method, ‌ adsorption method, etc. It is to protect the environment and purify air.

The cost of hazardous waste incineration plant

The scale of investment in waste incineration plants depends on the region, technical level, equipment selection, and other factors. The specific investment needs to be planned and evaluated in detail according to the actual situation of the project.

item	cost	Year running cost (Tens of thousands)
Space expenses	USD 28/mu	USD 28/mu*10=USD280
Incineration equipment	USD 280	USD 280
Environmental protection equipment	USD 70	USD 70
Cost of labor	USD 4/person/year	USD 4/person/year*5 person=USD 20
Other cost	USD 28	USD 28
Total		USD 678

For reference only, different output can be customized.
