The kiln tail of knot machine 6 is equipped with third feed inlet 24, and kiln hood is equipped with third discharge port 27.The second of multisection type shearing-crushing dryer 5
Since position is lower, the material of output need to be promoted by conveyer belt discharge port 23 first, then be delivered to third feed inlet
24, into inside sintering machine kiln body 26.Sintering machine kiln body 26 has certain gradient, and kiln hood is lower, and kiln tail is higher, so that object
Material can voluntarily flow in kiln body.It can be heated by natural gas in sintering machine kiln body 26, naturally it is also possible to use other
Heat-agglomerating mode.Sintering machine kiln body 26 is set up on sintering machine support base 25, realizes bulit on stilts.
As shown in fig. 6, high temperature smelting furnace 8 is used to carry out melt process to by drying, broken, sintering material.High temperature
The shell of melting furnace 8 is made of heat-resisting material, and top is equipped with the 4th feed inlet 28 and the 4th Waste gas outlet 29.Sintering machine
6 third discharge port 27 connects the feed inlet of charging gear 7, is controlled from charging gear 7 to the inlet amount of high temperature smelting furnace 8.By
In melting process, it may be necessary to add the substance of other components, therefore charging gear 7 can be equipped with additional multiple chargings
Mouthful, high temperature smelting furnace 8 is delivered to after material is mixed again.4th charging of the discharge port connection high temperature smelting furnace 8 of charging gear 7
Mouthfuls 28, it is the molten bath 31 for being melted to material below the 4th feed inlet 28, and be equipped in molten bath 31 for providing melting
The heating device 30 of heat.Heating device 30 can be any device for enabling to material melts, and can be open fire can also be with
It is electric heating etc., in the present embodiment, heating device 30 mends wind integrated pipe using combustion of natural gas, integrates tube inlet and external day
Right gas feeding mechanism is connected.It is with the combustion of natural gas pipe for mending wind function, external natural gas that combustion of natural gas, which mends wind integrated pipe,
The natural gas and air of feeding mechanism supply can enter in pipe together, then spray from ozzle, in the form of jet flames pair
Material carries out heating melting.The material of melting is stored in molten bath 31, is equipped with the 4th discharging on 31 side wall of molten bath at certain altitude
Mouth 32.4th discharge port 32 is one article of pipeline resistant to high temperature, and pipe end is located at 33 top of watch-quench tank, and molten liquid can be directly in weight
It is fallen into open watch-quench tank 33 under power effect.Watch-quench tank 33 is an open groove body, and side wall is intake equipped with recirculated water
Cooling water can be inputted recirculated water water inlet 34 by water pump, then from recirculated water water outlet by mouth 34 and recirculated water water outlet 35
35 discharges realize that circulation keeps water temperature inside.Watch-quench tank 33 is in use, it may appear that the precipitating of part residue, therefore its
It needs to be equipped with slag-draining device 36 in inner cavity.Various residue extraction mechanisms in the prior art can be used in slag-draining device 36.
In addition, since sintering machine 6 and high temperature smelting furnace 8 have extra power input in the present invention, in the flue gas discharged
There can be more heat, this partial heat can be used for two sections of rail mounted drying kiln 4 and multisection type shearing-crushing dryer 5
Formula drying course.Its specific implementation are as follows: thermal energy converter is equipped in the inner cavity of sintering machine 6 and high temperature smelting furnace 8, it is right
Flue gas heat carries out recovered flue gas heat, and thermal energy converter can be the structures such as tubular sheet heat exchanger, plate-fin heat exchanger.It is external cold
Air inputs in the heat exchanger tube of thermal energy converter, is exchanged heat by heat exchange tube wall and external hot fume, then again from hot empty
Gas outlet output.As previously mentioned, being equipped with the first air blower 17 in rail mounted drying kiln 4, set in multisection type shearing-crushing dryer 5
There is the second air blower 22, therefore the hot air outlet of the thermal energy converter in sintering machine 6 passes through the second hot air pipe 11 connection first
The air inlet of air blower 17, the hot air outlet of the thermal energy converter in high temperature smelting furnace 8 pass through the first hot air pipe 10 connection the
The air inlet of two air blowers 22.By the negative-pressure ward of the first air blower 17 and the second air blower 22, attraction is generated, it will be hot empty
Gas continually enters in each drying section, realizes that fume afterheat utilizes.
In addition, since a large amount of flue gas can be generated in the disposal process of the processing unit, it is therefore desirable to the first exhaust gas be arranged
Processing unit 12 and the second emission-control equipment 13.First emission-control equipment 12 and the second emission-control equipment 13 can be phase
With, be also possible to it is different, type selecting needs be determined according to the property of different exhaust gas.In general, rail mounted is dried
The exhaust gas properties generated in kiln 4 and multisection type shearing-crushing dryer 5 are similar, both connect the second exhaust gas by exhaust piping
Processing unit 13；The exhaust gas constituents generated in sintering machine 6 and high temperature smelting furnace 8 are complex, both connected by exhaust piping
Connect the first emission-control equipment 12.It in the present embodiment, include condenser, dual firing chamber, chilling in the first emission-control equipment 12
Facility, denitration facility, desulfurization equipment, depickling facility and dust removal installation include condenser in the second emission-control equipment 13 and are removed
Dirt facility.
Due to the most complicated component of hazardous waste, and different Hazardous Characteristics of Hazardous Wastes significant differences, therefore processing of the invention
Broken and homogenizing workshop section is pre-set in device, so that the material into subsequent handling is relatively stable.In addition, hazardous waste is big
More moisture content are higher than 60%, and large quantity of moisture, which enters high temperature workshop section, will increase energy consumption, therefore is provided with two-part and dries.It will dry
It is for the first time in drying course that journey, which is divided into the reason of two-part, and such material is easy to produce hardened phenomenon, produces to follow-up sintering process
Raw adverse effect, therefore shearing-crushing is provided in the second half section of drying.In addition, part hazardous waste contain the halogens such as fluorine chlorine and
Organic pollutant, this moieties access effective removing in sintered ring energy conservation, alleviate the pressure of subsequent melt link, prolong
The service life of fusion apparatus is grown, it is ensured that the stable emissions of flue gas.It is main by the hazardous waste after drying, sintering, melting
Ingredient is oxide, can form vitreum after rational proportion by water quenching, is realized innoxious.
In the present invention, handled hazardous waste is siliceous, golden containing alkali in " National Hazard waste register (2016 editions) "
Belong to or flammable class hazardous waste, these waste residues pass through rational proportion, glass melt can be formed, wherein siliceous, alkali metal containing can
To be to burn industry waste residue, metallurgy industry waste residue, the organic matter in flammable class hazardous waste can burn in the case of a high temperature, reduce
Energy consumption.
