Line frequency and/or aperture are controlled, so that entering the substance to be processed in combustion chamber 2 and the combustion position in combustion chamber 2
Match, to reach optimal combustion state.
Further, it is preferable to ground, another use of the first air duct 422 for conveying fresh air, in the second air duct 442
In conveying substance to be processed；Further, according to the gas characteristic of the conveying in the first air duct 422 and the second air duct 442, the first wind
Machine 46 selects axial flow blower to ensure that fresh air and substance to be processed enter in combustion chamber；Second blower 48 is centrifugation wind
Machine, the blade of centrifugal blower can be set in the second air duct 442, and the setting of the components such as motor is in 442 outside of the second air duct, in turn
Effectively the components such as motor is avoided to be influenced the service life by the pollution of the substances such as flue gas impurity.
In specific embodiment, (arrow as shown in the figure is that fresh air flow direction and bitumen flue gas flow as depicted in figs. 1 and 2
Direction), combustion system 1 by dust collection pipe collection Lai bitumen flue gas introduce burner 10 by filter 30, subsequently into
Drying roller 50, bitumen flue gas go directly flame kernel, are converted into carbon dioxide and water by high temperature incineration.Specifically, the burning
System 1 includes: combustion chamber 2, which has internal layer combustion chamber 22 and outer layer combustion chamber 24, in diffuser 222 and straightway
224 have porous structure, hold together formation narrow slit at fiery section 226 first.422 outlet side of 22 entrance of internal layer combustion chamber and the first air duct
Connection, as an air duct, 24 entrance of outer layer combustion chamber is connect with bitumen flue gas outlet side, as secondary air duct, First air warp
It crosses stable flame pan 16 and generates eddy flow, Secondary Air holds together the positions such as fiery section 226 point from the diffuser 222 of combustion chamber 2, straightway 224, first
Multistage be sent into combustion zone, multistage air-supply can make air and flue gas it is more efficient participation burning reach better efficiency of combustion and cigarette
Gas purifying rate；Two-layer stratigraphic structure keeps the radiating condition of combustion chamber 2 more excellent, helps to reduce 2 over-heated fault of combustion chamber, improves burning
2 service life of room；Main body 4, main body 4 are two-layer equation tube structure, and main body 4 includes the first cylinder 42 and is set in the first cylinder 42
The second outer cylinder 44,42 stroke of the first cylinder have the first air duct 422 of internal layer, shape between the first cylinder 42 and the second cylinder 44
At the second air duct 442 positioned at outer layer being isolated with the first air duct 422；The first air duct 422 of internal layer is arranged in axial flow blower

2 one end；Rack 60 is arranged in rack 60 with upper-part；The outer layer feed inlet of the air outlet of centrifugal blower and the second cylinder 44
Docking, bitumen flue gas is drawn through the second air duct 442 of outer layer by centrifugal blower and outer layer combustion chamber 24 is sent into combustion chamber 2, makees
It participates in burning for Secondary Air；The air outlet of axial flow blower is docked with the air inlet in the first air duct of internal layer 422 of the first cylinder 42, newly
Fresh air enters axial flow blower from silencer cover, and is admitted to the interior of combustion chamber 2 by the first air duct of internal layer 422 of the first cylinder 42
Layer combustion chamber 22 participates in burning as First air；Bitumen flue gas in the whole process not with the motor of centrifugal blower, axial flow blower
Motor, flame detector 14 and ignition module be in contact, avoid the flue gas deposition scaling loss that leads to that the motor feels hot, can't detect flame
The failures such as signal or ignition difficulties.Centrifugal blower is run in use with specific frequency or aperture, is carved with when guaranteeing enough
Suction capactity fume collection is clean.The frequency or aperture of axial flow blower are adjusted according to combustion state, and control shaft stream wind
The air quantity of machine 10 total blast volume of burner ratio between 10% to 30%, flame control it is finer, combustion efficiency is more preferable.
Further, main body 4 has the first air duct of internal layer 422 and the second air duct of outer layer 442, removes entrance between each layer cylinder
Except outlet, it is mutually isolated and is not connected to, the first cylinder 42 and the second cylinder 44 have a maintenance door, and maintenance door is closed when work,
It is openable when maintenance.
In conclusion two blowers of the combustion system 1 of the utility model, mutually isolated double air channel structures, combustion chamber 2
Using two-layer equation combustion chamber structure, pure air and flue gas to be processed pass through the through flame region ginseng of Double layer burning chamber
With burning, efficiency of combustion and gas cleaning rate are preferably improved；Two-layer stratigraphic structure keeps the radiating condition of combustion chamber 2 more excellent, has
Help reduce 2 over-heated fault of combustion chamber, improves the service life of burner 10.Further, centrifugal blower is used to collect flue gas,
Axial flow blower is used to provide fresh air for combustor, and fresh air and flue gas are sent into combustion zone in proportion as needed, received by two kinds of blowers
The flue gas that collection comes is not in contact before entering combustion chamber 2 with blower main parts size and ignition module completely, so as to avoid
Pollution problem.10 reliability of burner is not influenced by flue gas, and can adjust centrifugal blower fresh air and axis according to combustion position
The flue gas ratio that flow fan is collected keeps combustor burning more abundant.That is, two fans are 10 air feed of burner, air quantity ratio is adjustable
It is whole, realize that the feature of environmental protection and economy are unified；Two-layer equation tube structure realizes that flue gas is separated with fresh air；Flue gas is in burning
It is preceding not contacted with 10 kernel component of burner, to avoid the pollution of 10 kernel component of burner, improve burner 10
Reliability；Make full use of the ability of burner 10, not only realized flue gas collection and but also meet the air distribution of burning, can reduce
Bituminous mixing plant entirety installed power；Bitumen flue gas is burned by the second air duct 442 flame kernel that goes directly, treatment effect
It is good, problem without secondary pollution.
