Description

Burning-plasma non-hazardous waste treatment system

Affiliated technical field:

The utility model relates to a kind of system of harmless treatment refuse, exactly is a kind of burning-plasma non-hazardous waste treatment system, is particularly useful for the minimizing of all types of industries, medical treatment, life the like waste, the processing of innoxious and recycling.

Background technology:

Along with rapid economic development, the generation of solid waste is in continuous increase, and a large amount of solid waste has caused the serious environmental pollution problem.Because existing burning disposal and exhaust gas cleaner can produce a large amount of De bioxin, cause harm potential or reality to environment.Bioxin belongs to chloro three rings and contains oxygen aromatic hydrocarbons organic matter, very low dose will produce illeffects to organism, and be extremely long pollutant of duration in environment, toxicity is extremely strong, is a human class carcinogenic substance, have physiology toxicity and neurotoxicity, suppress immunologic function, disturb endocrine function, may cause that the male sex feminizes as environmental estrogens, because its height lipophilicity is discharged than difficult in the fat in case the absorption human body stockpiles in vivo.According to the characteristic of bioxin, incinerator aerobic and low ignition temperature are difficult to reach the bioxin decomposition temperature.China incinerator institute exhaust gas discharged is when spraying without active carbon; the bioxin content results often is higher than country and allows the hundred times of discharge standard to thousands of times, but though after charcoal treatment De bioxin decrement and up to standard in the waste gas, but coming down to a gas Zhong bioxin is adsorbed onto in the active carbon, the hazardous waste that contains a large amount of bioxin compositions is sent to landfill yard, has buried potential danger to the mankind.In addition, refuse need consume lot of energy when burning, and more or less all has a certain amount of organic principle in the refuse, and its organic principle is burnt the resources advantage of failing to make full use of himself in vain.Nowadays, the method that a kind of plasma technique is handled hazardous waste occurs, it is fast to have firing rate, the cracking temperature height, advantages such as discharging cleaning, having obtained the consistent of domestic and international environmental administration approves, its principle is by the cracking of plasma anaerobic, with the thermal decomposition of harmful substance under high-temperature reductibility atmosphere, harmful element and other heavy metal enter the vitreum directional migration and realize that the vitreum rock-steady structure forms, slag after burning and the flying dust in the tail gas are carried out atmosphere with plasma split harmless treatment, when enough high temperature reducing atmosphere cracking refuse, cracking is very thorough, Ji the damage capability of bioxin is extremely strong, owing to be oxygen-free environment, there is not the synthetic again condition of tail gas cooling Shi bioxin in organic matter in the slag, it is fast to have firing rate, the cracking temperature height, secondary pollution is few, advantages such as discharging cleaning, but have high input, need high energy consumption in the processing procedure, the operating cost height, the domestic so far example of applying.

The utility model content:

In order to address the above problem, the utility model provides the less relatively burning of a kind of equipment investment-plasma non-hazardous waste treatment system, can be continuously, steady operation, and reach good performance driving economy, compare with existing incineration technology, when hazardous waste obtains significantly loss of weight and subtracts appearance, realized non-pollution discharge.

The technical solution of the utility model is: a kind of burning-plasma non-hazardous waste treatment system, comprise that feed system, CIU, gas-purification utilize system, plasma anaerobic cracking system and exhaust treatment system to form, its feed system can adopt hydraulic pressure propulsion mode, spiral feeding manner etc., and CIU comprises compositions such as furnace body, slag output mechanism and tail gas discharger.Plasma anaerobic cracking system comprises that the slag after plasma generating assembly, power supply, plasma-reaction-chamber, feeding mechanism, the processing is discharged and assembly such as gas emission device.Exhaust treatment system mainly has been the effect that the tail gas after the purification plasma treatment reaches discharge standard, comprises the collection of solid matter-flying dust in the tail gas, can adopt structures such as Electrostatic Absorption, spraying and dedusting or cloth bag collection.

The flow process of system works is that object being treated enters CIU by conveying device and burns, the gas of discharged in burning is sent into plasma system and is carried out anaerobic cracking harmless treatment, handle back up to standard discharging by exhaust system again, the particulate matter that exhaust system is collected and the slag of burning carry out landfill after the harmless treatment by the plasma apparatus system, also can be used as utilizations such as construction material raw material.

The beneficial effects of the utility model are: the utility model is the emission (flying dust of slag and tail gas) after burning to be sent into plasma system carry out anaerobic cracking harmless treatment; utilize the low relatively advantage of the big cost of investment of burning disposal amount; emission after the burning decrement is handled with the cracking of plasma anaerobic again; the combination of burning and plasma anaerobic cracking treating equipment; can overcome plasma apparatus again when obtaining the harmless treatment effect has high input; complicated; the operating cost height; be not suitable for the deficiency of mass disposal; both combinations of burning-plasma anaerobic cracking can realize the scale of waste disposal; minimizing is handled, and the effect of really accomplishing harmlessness disposing.
