Abstract
The invention discloses a kind of rice husk fluidization reverse burning methods, include the following steps：The impurity such as silt in rice husk are cleared up and dried first；Rice husk is put into feed opening, is sent into combustion chamber from hopper through feeding serew；Start air blower, air is entered by air blower from bottom of combustion chamber, and makes rice husk that fluidization be presented；Fluidised rice husk comes into full contact with air in the combustion chamber, burns to realize that fluidization is counter；After the completion of combusting rice hull, stops feeding and close air blower and driving device.By the present invention in that fluidised rice husk and air, which come into full contact with, can both guarantee bed permeability, keep burning more abundant, improves efficiency of combustion, and the generation of black smoke can be reduced, avoid environmental pollution；Feeding is carried out using feeding serew, the additional amount of rice husk is can conveniently adjust and process is continuous, so that the combustion continuation of combustion chamber be kept to stablize.
Description
Technical field
The present invention relates to the fluidization of rice husk and its anti-burning technology field more particularly to a kind of anti-sides of burning of rice husk fluidization
Method.
Background technique
Rice husk accounts for about the 20% of paddy quality grain, is main agricultural waste.More than 75 country's plantation water in the world
Rice, annual yield are more than 500,000,000 tons, the corresponding rice husk rubbish generated more than 100,000,000 tons.China is that rice yield is highest in the world
Country accounts for about 1/3 or more of world's rice yield, and rice husk is resourceful, if rice husk effectively can be used, change give up into
Treasured can bring very big economic benefit.
The utility value of rice husk is main at present or meeting people by directly burning produces movable needs, still,
Since rice husk ash is high, is not easy the features such as after-flame, the efficiency of combustion of rice husk is often very low, and the rice husk of inabundant after-flame
Being easy to produce black smoke causes to pollute environment.Therefore, how to make rice husk quickly and effectively and adequately burning is that the present invention to be solved
The problem of.
Summary of the invention
The purpose of the present invention is overcome the deficiencies of the prior art and provide one kind to make rice husk quickly and effectively and sufficient burning side
Method.
To solve the above problems, technical scheme is as follows：Feeding is carried out by feeding serew, guarantees adding for rice husk
It is continual and steady to enter combustion chamber, makes rice husk that fluidization be presented by air blower, is sufficiently contacted with air, keep burning more abundant, specifically
Steps are as follows：
A, the impurity such as silt in rice husk are cleared up and is dried first；
B, rice husk is put into feed opening, is sent into combustion chamber from hopper through feeding serew；
C, start air blower, air is entered by air blower from bottom of combustion chamber, and makes rice husk that fluidization be presented；
D, fluidised rice husk comes into full contact with air in the combustion chamber, burns to realize that fluidization is counter；
E, after the completion of combusting rice hull, stop feeding and close air blower and driving device.
Preferably, one end of the feeding serew in the step b is fixedly connected with driving device by shaft coupling, the other end
It is fixedly welded with reverse acting spiral.
Preferably, the combustion chamber in the step c and step d is located at right above feeding serew and reverse acting spiral junction,
Feeding serew and reverse acting spiral junction are arranged right below air distribution plate, and air distribution plate lower part is connect by air hose with air blower.
Technical effect and advantage of the invention：
1, fluidised rice husk and air, which come into full contact with, can both guarantee bed permeability, keep burning more abundant, improve combustion
Efficiency is burnt, and the generation of black smoke can be reduced, avoids environmental pollution；
2, feeding is carried out using feeding serew, can conveniently adjust the additional amount of rice husk and process is continuous, to keeps
The combustion continuation of combustion chamber is stablized.
Detailed description of the invention
Fig. 1 is using the device of the invention structural schematic diagram.
In figure：1- feed opening, 2- feeding serew, 3- air blower, 4- air distribution plate, 5- reverse acting spiral, the combustion chamber 6-, 7- material
Slot, 8- driving device.
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 every other
Embodiment shall fall within the protection scope of the present invention.
Embodiment 1, a kind of rice husk fluidization reverse burning method, include the following steps：Before combusting rice hull, first by the mud in rice husk
The impurity such as sand are cleared up and are dried；Then rice husk is put into feed opening 1, is sent into combustion chamber 6 from hopper 7 through feeding serew 2；It opens
Dynamic air blower 3, air is entered by air blower 3 from 6 bottom of combustion chamber, and makes rice husk that fluidization be presented；Fluidised rice husk exists
It comes into full contact in combustion chamber 6 with air, is burnt to realize that fluidization is counter；After the completion of combusting rice hull, stops feeding and close air blast
Machine 3 and driving device 8.
Referring to Fig. 1, one end of the feeding serew 2 in step b is fixedly connected with driving device 8 by shaft coupling, it is another
End is fixedly welded with reverse acting spiral 5, is conducive to the underface that rice husk is gathered in combustion chamber 6；
Wherein, the combustion chamber 6 in step c and step d is located at right above feeding serew 2 and 5 junction of reverse acting spiral, feeding
Spiral 2 and 5 junction of reverse acting spiral are arranged right below air distribution plate 4, and 4 lower part of air distribution plate is connect by air hose with air blower 3, can be with
Reduce air blast resistance, keeps rice husk fluidization more abundant.
It is advantageously implemented the fluidization of rice husk using the present apparatus, guarantees that rice husk to be combusted comes into full contact with air, makes rice
Shell burning is more abundant, improves efficiency of combustion, and 2 feeding continuous uniform of feeding serew keeps combusting rice hull in combustion chamber 6 to continue surely
It is fixed.
Finally it should be noted that the present invention is in addition to can be used for combusting rice hull, it may also be used for the physicochemical properties such as sawdust are similar
Or the burning of similar other biological matter fuel.
