Background technique
Containing harmful heavy metals substances such as a large amount of Cd, Cr, Ni, Pb in incineration of refuse flyash, and many height are adsorbed
Toxicity persistence organic pollutant difficult to degrade.Therefore, " National Hazard waste register " clear stipulaties its be hazardous waste, it is necessary to
Through overstabilization, harmless treatment.Currently, the processing method of more common incineration of refuse flyash mainly has isolation technics, solidification
Stabilization technology and heat treatment technics.
The new technology that plasma technique is used widely in the industry in recent years as one kind, can be used for rubbish
The processing of flying ash.Compared with traditional heat treatment technics, heat plasma technology has higher temperature and energy density,
The vitrifying of flying dust may be implemented, inhibit heavy metal transformation, it is considered to be the harmless processing one of the most effective ways of flying dust.
The operating cost of corona treatment flying dust is quite high, is typically necessary by government subsidy.Using plasma skill
Product after art processing flying dust is common building stones, is only used for the industries such as paving the way or build, one ton is only had hundred bucks or so.It is molten
Rock treatment effect it is better can produce vitreum, be used to prepare glass fibre, one ton of price can reach 1000 yuan of left sides
It is right.But the operating cost of corona treatment flying dust is very big, although the vitreum price being prepared into is relatively high, is difficult to fill up
The operating cost of whole system.
Therefore, it is necessary to find a kind of experimental provision of at low cost, high-efficient processing flying dust, can simply and effectively carry out
Handle flying dust experiment.
Utility model content
In view of the defects existing in the prior art, the utility model provides a kind of experiment knot for handling flying dust and preparing bead
Structure can effectively solve the above problems.
The technical solution adopted in the utility model is as follows:
The utility model provides a kind of experimental configuration for handling flying dust and preparing bead, including electrode (1), furnace body (3), water

The cathode in source connects with the electrode (1).
Preferably, the power supply is Inverter Used in Plasma Cutting or the source of welding current.
Preferably, the electrode (1) is carbon-point or welding rod.
The experimental configuration that processing flying dust provided by the utility model prepares bead has the advantage that
The utility model is a kind of experimental provision for being suitable for flying dust processing at low cost and high-efficient, can be simple and effective
Ground carries out flying dust processing, and certain practice and theoretical direction are provided for industrial treatment flying dust.
Specific embodiment
The technical issues of in order to keep the utility model solved, technical solution and beneficial effect are more clearly understood, below
In conjunction with accompanying drawings and embodiments, the present invention will be further described in detail.It should be appreciated that specific implementation described herein
Example only to explain the utility model, is not used to limit the utility model.
The utility model provides a kind of experimental configuration for handling flying dust and preparing bead, is applied to environmental protection industry (epi) and handles rubbish
Flying dust, can be prepared a kind of higher product of price by the secondary pollution (flying dust) after burning, and have it is at low cost and
High-efficient advantage can simply and effectively carry out flying dust processing, and provide certain practice and theory for industrial treatment flying dust
Guidance.
With reference to Fig. 1, handling flying dust and preparing the experimental configuration of bead includes electrode 1, furnace body 3, sink 5 and power supply;
Wherein, furnace body 3 is using round steel drum;The main body of furnace body 3 is placed inside screw clamp 5;The top of furnace body 3 hangs installation
Electrode 1;Electrode 1 uses carbon-point or welding rod;Power supply uses Inverter Used in Plasma Cutting or the source of welding current, and power supply is just
Pole connects with furnace body 3;The cathode of power supply connects with electrode 1.
The application method of the utility model are as follows:
Furnace body is placed in screw clamp, cooling water is put into sink;Furnace body is connect into the anode of power supply, electrode connects power supply
The cathode of power supply will first put a little iron filings and generate electric arc, high-temperature electric arc between electrode and iron filings after power supply is powered in furnace body
Moment iron filings can be melted to form molten bath, launch flying dust successively to bath, it is molten for melting moment when flying dust is fallen into furnace body
Rock, flying dust after thawing will be conductive, hereafter will no longer need to add iron filings toward furnace interior, continue to add that flying dust is i.e. certifiable to be held
Continuous be powered generates electric arc.
Then, until lava continuous enlargement in furnace body, when lava rises to fire door, electrode is protruded into furnace body in lava, electricity
Arc current will increase moment, and lava in furnace body is caused to boil, and the molten drop boiled out instills meeting after the cooling water in sink
Instantaneous temperature reduction, forms a quenching process, and the molten drop of melting also can solidify to form bead moment.
Specifically, relative to existing experimental provision, the utility model is also had the advantage that
1) structure is simple: the utility model is exactly the structure letter by commonly welding or plasma power supply, steel drum, sink form
It is single, convenient for experiment.
2) utilization rate of cooling water is high: there are two effects, one to cool down for furnace body for the cooling water of the utility model, and two
The drop of melting can be quenched, improve the utilization rate of water.
3) can prepare bead: sphere material has many excellent physics and mechanical performance, the valence of any sphere material
Lattice will be more much higher than the price of same material, and the bead being prepared into can also be used to do ornament, toy, jewellery etc., greatly
The price of flying dust processing product is improved greatly.By preparing bead, flying dust treated product will no longer be waste or cheap
Building stones, but the product with high value, can make corona treatment flying dust no longer is the project spent, but the item made money
Mesh.
Processing flying dust provided by the utility model prepares the experimental configuration of bead, has the advantage that
The utility model is a kind of experimental provision for being suitable for flying dust processing at low cost and high-efficient, can be simple and effective
Ground carries out flying dust processing, and certain practice and theoretical direction are provided for industrial treatment flying dust.
The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art
For art personnel, without departing from the principle of this utility model, several improvements and modifications can also be made, these improve and
Retouching should also regard the protection scope of the utility model.
