Thickness, the cooled slag of lower floor can play a protective role to grate plate 200.
Dangerous waste thing is different from conventional house refuse.Silico-calcium constituent content is big in conventional house refuse, the stove produced after burning
Slag exists in solid form；Solid-state slag is all easily achieved using water-cooled or air-cooled pattern.And silico-calcium contains in dangerous waste thing
Amount is low, and magnesium, aluminium, fluorine element content are high, therefore slag is in molten state after high temperature incineration；Because the slag of molten state is easy to cementing machine
Device, it is air-cooled to be considered as the forbidden zone being difficult to by the technical staff in dangerous waste thing burning disposal field always, can only be using conventional water
Chill formula.And the structure design and motion mode that the utility model passes through above-mentioned air cooling slag hoist 2, can effectively overcome high temperature melting
Melt the bonding of slag, so that the air-cooled pattern of dangerous waste thing dregs of incinerator is achieved.
Referring further to Fig. 1, the exhanst gas outlet 113 of vertical incinerator 100 passes through the bottom air inlet of pipeline and secondary combustion chamber 30
Mouth 301 is connected.The top offgas outlet 305 of secondary combustion chamber 30 is used for being connected with exhaust treatment system.In vertical incinerator 100
Flying dust expansion chamber 150 is preferably provided with the connecting line of secondary combustion chamber 30, for settling and collecting flying dust in flue gas, is subtracted
Enter the solid particle in secondary combustion chamber 30 in flue gas less.The bottom of flying dust expansion chamber 150 is provided with Dual-gravity cindervalve
151, for the flying dust that outwards conveying is collected.It is very small due to entering fly ash content in the flue gas in secondary combustion chamber 30, therefore
The grey quantity of slag produced in secondary combustion chamber 30 is just little, therefore only need to set shoot door 310 in the bottom of secondary combustion chamber 30, two
Shoot door 310 is opened when not working and pour out lime-ash in level combustion chamber 30.
The bottom of secondary combustion chamber 30 is provided with Secondary Air entrance 304, is connected with secondary blower, to secondary combustion chamber
Sufficient air is provided in 30 and ensures that cracked gas are fully burned.Secondary Air entrance 304 is connected with annular gas distribution
Device 306, around the perisporium multiple nozzles of arrangement of secondary combustion chamber 30, for equably to filling into air in secondary combustion chamber 30.
In addition, the bottom of secondary combustion chamber 30 can also be provided with auxiliary combustion equipment (not shown), in secondary combustion chamber 30
Middle penetrating afterburning gas carries out combustion-supporting or igniting.
The introduction of lower mask body is according to vertical incinerator of the present utility model and the operation principle of dangerous waste thing subregion CIU
And the course of work.
General plotting of the present utility model is to make to treat that incinerated matter (such as dangerous waste thing) first carries out cracking gas, forms fixed carbon
Then their subregions are burnt by part and cracking gas part again.
In vertical incinerator 100, motion from top to bottom sequentially passes through feed zone after incinerated matter is from the entrance of charging aperture 111
110th, cracking section 120, incineration section 130, section of slagging tap 140.Treat that incinerated matter is toasted in cracking section 120 by high temperature, complete cracking
Gasification, forms solids (mainly containing fixed carbon) and cracking gas (mainly containing alkanes, hydrocarbon component).Through consolidating after high-temperature baking
Body thing enters incineration section 130 under the drive of fire grate 131.Flue gas, together upwardly through the bed of material, is carried out with pyrolysis gas to the bed of material
Preheating and baking, make material to be burned fully be dehydrated, and the bed of material plays a role in filtering to flue gas, is greatly lowered in later stage flue dust
Dust concentration, mitigate later stage exhaust treatment system load.The low flue gas of dust content and cracking gas together enter two grades of combustions
Burning room 30 carries out secondary after-flame.
First air enters from air inlet 23, through air cooling slag hoist 2 and high temperature furnace slag heat exchange, reduces slag temperature, and one
Secondary air temperature is raised.The supply of First air air quantity is needed according to determination of oxygen content instrument real-time regulation in stove, it is ensured that incineration section 130 is fitted
Amount oxygen supply, the fuel gas cracked out in cracking section 120 can not burn.
A big feature of the present utility model is that gas-solid is driven in the wrong direction, and material is fully dried, and is burned close to entering when burning-point
Section, incineration section is thoroughly carbonized burning-up.The bed of material filters substantial amounts of dust, and the cleannes of gas are higher.And existing+two grades of rotary kiln
The CIU of combustion chamber, material carries out mixed combustion (not only cracked but also burnt) in rotary kiln, containing big in the flue gas of generation
Amount solid particle, needs to fill into a large amount of afterburning gases when being burnt in secondary combustion chamber；And the dust content in tail gas is high, plus
The big difficulty of follow-up vent gas treatment.
Additionally, another big advantage of the present utility model is the air-cooled pattern of slag.And produced by tradition danger waste incinerator
Slag can only use water-cooled pattern, and the vapor in cooling procedure enters the ignition temperature that incineration section can reduce incineration section, influence
Quality is burned, the slag after water-cooled generally using mode is dried, ooze in ground in slag by the sewage major part containing high pollution composition
Under, form secondary pollution.And the utility model uses the air-cooled pattern of slag, slag is cooled down in the case of not in contact with the ground
And conveying, the energy and saving water resource both having been made full use of, can prevent the pollution of the environment again.
