General cause waste, for example, thermally treated harmful dust and slag with after incineration process and some with toxic
Waste can cause secondary pollution to environment because it is without recycle value, it usually needs by its melt process, currently, processing
The melting furnace of these wastes all has offgas outlet and slag exit, and the pipeline where the two outlets is generally to be independently arranged
, since the slag fluidity generated after castoff fusing is poor, the discharge of slag often will produce stagnation behavior.Therefore, existing
Waste melting furnace there is a problem of the slag fluidity generated after castoff fusing difference.
Utility model content
The purpose of the utility model is to provide a kind of waste melting furnaces.The utility model improves castoff fusing
The mobility of slag afterwards.
The technical solution of the utility model：Waste melting furnace, including furnace wall, furnace wall bottom are connected with supporting leg, furnace wall top
Portion is equipped with blind flange, and furnace wall side wall is equipped with feed inlet, and feed inlet is connected with batcher, and batcher is connected with feed bin, is set in furnace wall
There are burner hearth, burner hearth bottom to be equipped with molten bath, molten bath is equipped with portion of slagging tap, and is equipped with slag exit through pipeline of slagging tap below portion of slagging tap, goes out
Slag portion side is equipped with offgas outlet through outlet pipe, and plasma generator is equipped on furnace wall.
In waste melting furnace above-mentioned, the pipeline of slagging tap is embedded in furnace wall bottom, and outlet pipe is embedded in furnace wall side
Wall, slags tap pipeline and outlet pipe is connected with each other through common pall.
In waste melting furnace above-mentioned, there are three plasma generator, two of which plasmas for installation on the furnace wall
Generator is mounted on the furnace wall below feed inlet.
In waste melting furnace above-mentioned, the batcher is spiral batcher.
Compared with prior art, the utility model heats waste by three plasma generators on furnace wall,
Castoff fusing effect is good, outlet pipe and pipeline of slagging tap is equipped in the shell of melting furnace, outlet pipe end goes out equipped with tail gas
Mouthful, line end of slagging tap is equipped with slag exit, and the flue gas generated after castoff fusing is discharged from offgas outlet, after castoff fusing
The slag of generation is discharged from slag exit, and outlet pipe is connected with pipeline of slagging tap through one section of common pall, can make full use of height
Warm flue gas preferably maintains the melt-flow state of outlet section slag, effectively prevents the stagnation of slag discharge.To sum up, this practicality
The novel mobility for improving slag after castoff fusing, in addition, melting furnace is heated by three plasma generators, melting
Effect is good.

Specific implementation mode
The utility model is further described with reference to the accompanying drawings and examples, but is not intended as to the utility model
The foundation of limitation.
Embodiment：Waste melting furnace, structure is as depicted in figs. 1 and 2, including furnace wall 1, and 1 bottom of furnace wall is connected with supporting leg
2,1 top of furnace wall is equipped with blind flange 3, and 1 side wall of furnace wall is equipped with feed inlet 4, and feed inlet 4 is connected with batcher 5, and batcher 5 connects
There is feed bin 6, burner hearth 7 is equipped in furnace wall 1,7 bottom of burner hearth is equipped with molten bath 8, and molten bath 8 is equipped with portion 9 of slagging tap, 9 lower section warp of portion of slagging tap
Pipeline 10 of slagging tap is equipped with slag exit 11, and 9 side of portion of slagging tap is equipped with offgas outlet 13 through outlet pipe 12, is equipped on furnace wall 1
Plasma generator 14.
The pipeline 10 of slagging tap is embedded in 1 bottom of furnace wall, and outlet pipe 12 is embedded in 1 side wall of furnace wall, 10 He of pipeline of slagging tap
Outlet pipe 12 is connected with each other through common pall 15.
There are three plasma generators 14, two of which plasma generator 14 to be mounted on charging for installation on the furnace wall 1
On the furnace wall 1 of 4 lower section of mouth.
The batcher 5 is spiral batcher.
Waste is entered by batcher 5 in melting furnace from feed bin 6, falls into molten bath 8, and division melting occurs in stove, leads to
Polycrystalline congruent melting is crossed, the Organic Hazardous Compounds cracking in waste becomes innocuous substance or combustible, heavy metal in slag out
After polycrystalline congruent melting, leaching rate is extremely low, can be used as resource reutilization product, flue gas and the slag common sparing of high temperature completely
Exit passageway.
Since the temperature in stove is very high, and waste is that harmful substance or band are corrosive, and furnace wall 1 uses high temperature resistant and resistance to
The high-strength castable of soda acid.
It melts the flue gas generated and shares one section outlet with slag, high-temperature flue gas can be made full use of preferably to maintain outlet section
The melt-flow state of slag.
The operation principle of the utility model：Waste is transported to through batcher 5 in melting furnace from feed bin 6, passes through feed inlet 4
It falls into molten bath 8, waste is melted into fluid using three plasma generators 14 installed on furnace wall 1, passes through polycrystalline
Congruent melting, the harmful substance cracking in waste, flue gas are discharged by common pall 15 and outlet pipe 12, and slag is through share pipe
Road 15 and pipeline 10 of slagging tap are discharged, and the flue gas and slag for melting generation have one section of common pall 15, can make full use of height
Warm flue gas preferably maintains the melt-flow state of outlet section slag.
When castoff fusing, waste is heated first with the heat that plasma generator 14 generates, makes to discard
Object is melt into fluid, and the organic matter in waste is made to decompose or gasify, and reaches minimizing and volume reduction effect, organic matter example
Ru bioxin；In addition, in waste other than organic matter, there is also organic/inorganic substance, inorganic matter such as nonmetallic substances, a huge sum of money
Belong to or heavy metal other than metal etc., when melting, the because of metal other than heavy metal or heavy metal in the inorganic matter is heated to be generated
It reacts and is transformed into stabilized substance, reach stabilization effect；Meanwhile it by the material of silicon-aluminum containing, by heavy metal or being harmful to
Substance arrests limit in fluid, without being dissolved, reaches stable curing effect, in the present embodiment, the plasma generator
The 14 heat fusing temperature generated are about 1400 DEG C.
