Specific embodiment
Below by specific embodiment and combine accompanying drawing the application is described in further detail.
As shown in figure 1, the embodiment of the present application provides a kind of processing equipment of flying ash, it includes the first ash silo 1, send
Grey pipeline 2, air preheater 3 and pyrolysis oven 4, the interior setting heating passage of pyrolysis oven 4, the first ash silo 1 is passed through ash feeding pipe road 2 and is somebody's turn to do
Heating passage is connected, and the gas outlet of air preheater 3 is connected with ash feeding pipe road 2.Flying ash can be transported to above-mentioned
In heating passage, and pyrolysis oven 4 can make to heat the problem rising in passage using resistive heater, reach heating with this and burn
Burn the purpose of flying dust.
In specific embodiment, can manually flying ash be added in the first ash silo 1, it would however also be possible to employ Pneumatic Conveying Mechanism
Flying ash is blown in the first ash silo.Air preheater 3 can be with connecting fan 5, and blower fan 5 can be by air suction air preheat
In device 3, air is heated and exports to ash feeding pipe road 2 by air preheater 3, and flying ash can be delivered to by this partial air
In pyrolysis oven 4.And pyrolysis oven 4 can heat flying ash so that the nuisance such as persistence organic pollutant in flying ash
Matter is decomposed.
From the foregoing, it will be observed that the processing equipment that the embodiment of the present application is provided is heated to flying ash using pyrolysis oven 4, with
This reduces the harmful substances such as the persistence organic pollutant in flying ash, and then alleviates the dirt that flying ash causes to environment
Dye.In addition, air preheater 3 can lift the temperature of air so that when air conveys flying ash, drying to flying ash
Dry.
In a kind of embodiment, above-mentioned air preheater 3 may include air preheater body and electric heating tube, this air preheater body
On there is air inlet, gas outlet and the air duct being communicated between this air inlet and gas outlet, electric heating tube is installed on this sky
In gas passage.Air passes through in air inlet air inlet passage, and electric heating tube can increase temperature in air duct so that sky
The temperature of the air in gas passage increases, and the air after heating is from outflow of working off one's feeling vent one's spleen.
Further, above-mentioned electric heating tube could be arranged to multiple, and each electric heating tube is sequentially communicated in air inlet and giving vent to anger
Between mouthful.Quantity with electric heating tube is continuously increased, and the temperature of air can be higher, thus lifting the baking of flying ash
Dry effect.
In order to lift the drying effect burning branch, the processing equipment that the embodiment of the present application provides may also include to be communicated in be sent
Dehydrator 6 between grey pipeline 2 and pyrolysis oven 4, this dehydrator 6 may include base, rotates the rotating cylinder being installed on base and energy
Enough drive rotating cylinder around the drive mechanism of own axis, rotating cylinder opens up ash inlet, ash hole and is communicated in ash inlet and goes out
Drying channel between grey mouth.The ash inlet that flying ash is passed through to open up on rotating cylinder sends into drying channel, simultaneously can be by driving
Motivation structure drives drum rotation so that applying centrifugal force to the flying ash in drying channel during drum rotation, and then will burn
Moisture in flying dust throws away, and realizes the drying of flying ash.Therefore, after using this dehydrator, flying ash is not easy to lump, with
It is easy to carry out subsequent treatment to flying ash.
If dehydrator 6 is directly connected with pyrolysis oven 4, then the amount of the flying ash flowing out in dehydrator 6 may be no
Method adapts to the capacity of pyrolysis oven 4, leads to pyrolysis oven 4 cannot be fully used.In view of this, above-mentioned processing equipment may also include
It is communicated in the second ash silo 7 between dehydrator 6 and pyrolysis oven 4.This second ash silo 7 can gather from dehydrator 6 flow out burn
Burn flying dust, guarantee have substantial amounts of flying ash to enter in pyrolysis oven 4 with this, and then improve the utilization rate of pyrolysis oven 4.
In a kind of embodiment, also sack cleaner 8 can be set, this sack cleaner 8 is connected with the first ash silo 1.Due to
Sack cleaner 8 is made using cloth, and it has certain breathability and filter capacity, both so that the inside of the first ash silo 1
Space is communicated with atmospheric environment additionally it is possible to prevent flying ash to be directly entered in air.
Further, exhaust duct 9 also can be set, and this exhaust duct 9 is communicated in exhaust outlet and the sack cleaner of dehydrator 6
Between 8.Because flying ash is continuously brought in dehydrator 6 by air, therefore the air in dehydrator 6 is accomplished by arranging
Go out, but because the flying ash in dehydrator 6 and air are admixed together, therefore can not directly discharge.And adopt
After stating exhaust duct 9, you can air draft is led back in the first ash silo 1, in case flying ash pollutes to air.In addition, in air draft
Gas can directly be returned in air after the filtration of sack cleaner 8, made with the circulation that this completes air
With.
In order to ensure to keep pressure-fired in pyrolysis oven 4, make in pyrolysis oven 4, to form the environment of anoxia or anoxybiotic simultaneously,
Nitrogen charging device 10 also can be set, and this nitrogen charging device 10 can be connected with the heating passage in pyrolysis oven 4.On this basis, it is
Improve the sealing of pyrolysis oven 4, water seal arrangement 11 also can be set, pyrolysis oven 4 opens up gas outlet, this water seal arrangement 11 connects
At this gas outlet.
Need to be delivered in sealing ash bin 12 through the flying ash of pyrolysis, therefore pyrolysis treatment apparatus may also include spiral
Feeder 13, the import of this feed screw 13 is connected with the discharging opening on pyrolysis oven 4, and its outlet is connected with sealing ash bin 12
Logical.Because the temperature of charge after pyrolysis is higher, the first chiller 14 therefore can also be set, set in this first chiller 14
Put the first cooling duct, feed screw 13 passes through this first cooling duct.First chiller 14 can by the way of water-cooled,
Cooling water can derive from tap water, and cooling water can be directly discharged to sewer after the first chiller 14 outflow.Therefore,
One chiller 14 can reduce the temperature of flying ash, is more safely stored in sealing ash bin 12 in order to flying ash.
Because the temperature in pyrolysis oven 4 is higher, therefore from pyrolysis oven 4 effluent air, there is higher temperature, now
Need this portion gas to be cooled down, in case the normal work of water seal arrangement 11 is affected.Specifically, this gas outlet is permissible
It is connected with water seal arrangement 11 by airway 15, the second chiller 16 can also be set in processing equipment, this second cooling
Setting the second cooling duct in device 16, airway 15 is passed through this second cooling duct, with this, gas in airway 15 is entered
Row cooling.Dust filter unit 17 can also be set between airway 15 and water seal arrangement 11, filter the dust in waste gas with this.
In addition, the processing equipment that the embodiment of the present application provides may also include separator 18, this separator 18 and the first ash silo 1
It is connected, before flying ash enters the first ash silo 1, initially enters separator 18, flying ash is carried out separate with this, thus
Prevent and treat and during subsequent treatment, equipment is caused with excessive burden.Sack cleaner 8 also can be connected with air compressor 19, real with this
The impulse soot blowing of existing sack cleaner 8, ensures the smoothness of sack cleaner 8 with this.
The foregoing is only the preferred embodiment of the application, be not limited to the application, for the skill of this area
For art personnel, the application can have various modifications and variations.All within spirit herein and principle, made any repair
Change, equivalent, improvement etc., should be included within the protection domain of the application.
