Description
Technical field
The present invention relates to boiler technology fields, are more specifically related to a kind of layer of burner, kiln is mixed and burned system.
Background technique
Traditional layer burner, kiln due to being burnt using coarse coal or Mixture Density Networks, colm as fuel, and due to
The setting of fire grate and unreasonable, the coal-fired extruding through coal flashboard of cloth wind, result in coal cinder burning and are not thorough, and two sides are leaked out,
It burns less than especially in burner hearth upper end due to lacking oxygen at center, it is easier to the halfway phenomenon of coal cinder burning is generated, in fire grate
The unburned complete coal cinder of end is often handled as the complete cinder that burnt, this not only causes great waste,
It is also easy to pollute.
Currently, solving layer burner, the method for kiln incomplete combustion is to improve combustion air temperature and improves burner hearth
Temperature.Wherein, due to being limited by grate firing boiler system and combustion apparatus itself form, air themperature can not be too high, leads to
Cross which solve layer burner, kiln incomplete combustion measure realize a possibility that it is lower, and current major measure be as
What improves fire box temperature, and typical way is to increase auxiliary pulverized coal combustion system on grate firing boiler, and pulverized coal combustion system can be with
Improve fire box temperature.But increases pulverized coal combustion system and also bring some problems, such as energy consumption increases, boiler fly ash amount increases, nothing
Method accurately controls the problem of dosage of coal dust.

Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts all other
Embodiment shall fall within the protection scope of the present invention.
Current layer combustion type kiln mainly uses coarse coal, Mixture Density Networks, colm as fuel, but due to the design of fire grate,
Extruding through coal flashboard, result in fire grate end coal cinder burning be not thorough, two sides are leaked out, central burner not exclusively, high temperature cigarette
Gas anoxic etc., not only results in the waste of fuel, also will cause serious pollution (generating black smoke), and solves the problems, such as this side
On the one hand method is to need to optimize fuel and (increase fine coal), guarantees that it can more thoroughly burn, on the other hand then mention
Temperature (oxygenation) in high-rise combustion type kiln, even if so that the position keeps high temperature, makes when guaranteeing that coal cinder reaches fire grate end
It can full combustion.
Such as Fig. 1, the present invention provides a kind of layer of combustion type kilns to be mixed and burned system, including feeding device 1, crushing device 3, drum
Wind apparatus 5 and floor fire room 10, and feeding device 1 is connect with crushing device 3 by conveying device, and blower device 5 and floor combustion room are logical
Main pipe connection is crossed, the end of crushing device 3 is connected on the main pipe between blower device 5 and floor combustion room.
The operation order of whole system are as follows:
The end of feeding device 1 is located at the top of hopper 21, and feeding device 1 (elevator or conveyer belt) first is defeated by coal cinder
It send to hopper 21, and topples in material bin 21, which is the initial position of feed screw 2, and feed screw 2 is by hopper
Coal cinder in 21 is delivered in crushing device 3 and crushes, which is mainly jaw crusher, impact crusher, hammer
The common coal crusher such as crusher, movable crusher, and such crusher mainly includes crushing bin and screening storehouse, is passed through
Crushing bin crushes coarse coal, and cracking cabin is inside and outside to be provided with magnet 31, can remove the iron in coal, smashed coal dust
Screening storehouse is fallen into, and the coal cinder not crushed then returns to crushing bin and continues to be crushed to form powdery.
Smashed coal dust is delivered to floor by air blower and fires in room 10, and floor fires the front end that room coal powder entrance is set to fire grate.
And the settable coal store on the main pipe that air blower is connect with floor combustion room 10, the coal store are mainly used for the storage of idle coal dust.
Currently, the commercial power standard in China is inconsistent, charged for some places according to the different electricity consumption periods, in ebb paddy
Often the electricity charge are lower for section, and its electricity charge of peak of power consumption period are higher, can carry out the crushing of coal cinder in ebb paddy for the situation,
And coal dust is stored in coal storage device 7.Coal storage device 7 include from top to bottom successively install cyclone separator 8, coal store with
And discharging device 6, coal dust can be precipitated in coal store by cyclone 8, and clean air then passes through and opens at the top of cyclone 8
Mouth discharge, the opening are provided with cloth bag 9, which can play the role of filtering, and coal dust is prevented to be discharged outside coal storage device 7
It gets into the air, and the air inlet that setting dust recycles 9 ' of collection conduit and blower device at bag-type dust outlet orientation connects
It connects, so that avoiding coal dust from being likely to travel through cloth bag is discharged into atmosphere.And be provided on discharging device 6 and manually or electrically switch, it switchs
Lower section be provided with check-valves, in addition the main pipe between branch pipe one, branch pipe two, branch pipe one and branch pipe two, branch pipe two and layer fire
It is provided with solenoid valve 4 on main pipe between room, and is connect with external control device, it can be to wind and coal dust by control device
More accurate proportion is carried out, to form energy conservation, layer combustion type kiln mixed firinor fuel burning system efficiently, environmentally friendly.In addition, firing room in floor
On be also connected with bag-type dust collector, the dust being discharged in air can be reduced to the maximum extent by increasing cleaner, and led to
It crosses air blower air inlet collection device dust collection is returned to storage tank or sprays into layer combustion Indoor Combustion, to realize energy conservation, efficient, ring
It protects, clean effect.
The present invention is by firing indoor increase air and coal dust in layer, to improve the fire box temperature of floor combustion room, traditional layer
The temperature for firing room is 800~900 DEG C, often leads to coal cinder center at this temperature and burns less than, especially fire grate end, and uses this
Layer burner, kiln are mixed and burned system, and the temperature of layer combustion chamber interior can achieve 1200 degree or more, on the one hand realize coal-fired height
Effect utilizes, and on the other hand reduces costs again, reduces coal-fired usage amount, estimated, the more traditional layer burner of this system,
Kiln, efficiency of combustion can be improved 10%~20%.
