Description
Technical field
The present invention relates to organic silicon byproduct synthesized environmental protection process fields, and in particular to a kind of preceding place of organic silicon slurry slag burning
The device of reason.
Background technique
Organic silicon slurry slag refers to a kind of waste residue slurry generated in organic silicon monomer synthesis process, accounts for amount of monomer about 3%, with
The rapidly extension of organic silicon monomer yield, supervene a large amount of organic silicon waste residue slurry, mainly composition be by more height
The silicon powder (partial size is in 2~150um) that boiling object and a small amount of fluidized bed are brought out, copper powder and microelement Fe, Zn, Al, Sn etc..Wherein
70.5~250 DEG C of high-boiling components boiling range, composition be mainly disilane, siloxanes, silicon support alkane, solid content is 20~75%.If
It is exposed in air, easily causes strong acid mist and burning, therefore, it is necessary to carry out harmless treatment to it.Currently, much having
Slurry is emitted on inside pond and is hydrolyzed by Ji Gui manufacturing enterprise, and the hydrogen chloride of discharge is seriously polluted, and a large amount of high-boiling components are not
It can recycle, fish out slag heavy workload, and the cuprous ion in slurry meets open fire and air easily causes to burn due to strong reducing property
And explosion, cause serious security risk.
Combustion method is to handle a kind of method of silicon screenings.Although strong sending and receiving can obtain silane monomer, wide to ingredient requirement
Pine does not need to remove some solid impurities in high-boiling components, can crack all silane.The shortcomings that burning pre-treatment is reaction temperature
Degree is higher, and carbon distribution is serious.Therefore need a kind of device that can reduce the carbon distribution problem in burning pretreatment process.
Summary of the invention
It is an object of that present invention to provide a kind of device of organic silicon slurry slag burning pre-treatment, which can effectively solve the problem that combustion
Burn the serious problem of the carbon distribution of processing organic silicon slurry slag generation.
The present invention is achieved through the following technical solutions：
A kind of device of organic silicon slurry slag burning pre-treatment, including rotary combustion furnace offer in rotary combustion furnace
First combustion chamber, rotary combustion furnace are connected with the second combustion chamber, the second combustion chamber and the first combustion chamber, the second combustion chamber
It is communicated with deduster, the air-supply region of at least two pieces opposite central axis settings is set on the first Inner Wall of Combustion Chamber, is blown at every piece
Multiple air outlets are offered on the corresponding inner wall in region along its length, are also opened along its length on the inner wall of every piece of air-supply region
Equipped with air supply duct, air supply duct is provided with the lower section of air outlet, and is connected to air outlet.
Three different feeding amount sections are divided into along the air supply direction of air-supply region, the first feeding amount section is first intensive
Blow zones, the second feeding amount section are the second evacuation blow zones, and third feeding amount section is the intensive blow zones of third, and first is intensive
The air outlet number of blow zones is greater than the air outlet number of the second evacuation blow zones, and the air outlet number of the intensive blow zones of third is big
Air outlet number in the second evacuation blow zones.The indoor organic silicon slurry slag of the first burning is generally sent to need more in first combustion
More heats and combustion air are so that it starts to burn, therefore should apply more combustion-supporting skies in the first feeding amount section
Gas.Below then because in contrast therefore combustion air that flameholding needs will lack, finally comburant is carried out sufficient
After-flame work, therefore be also required to increase air output in third feeding amount section.Air supply direction to be from the first entry of combustion chamber
The initial position of feeding.
Multiple air outlets are that dislocation is oppositely arranged.Dislocation is oppositely arranged the convection current that can make full use of relative atmospheric, will be right
The particulate matter that will adhere to or just be attached on inner wall that burning on the inner wall of face obtains is blown away.
Layer of titanium dioxide layer is coated on the inner wall of first combustion chamber.Titanium dioxide layer be for smooth, smooth coating,
It can aid in the generation for reducing carbon distribution.
Air outlet is loudspeaker diffused air outlet.Loudspeaker diffused air outlet is advantageous in that：When combustion air is from outlet air
After mouthful coming out, air-flow can against inner wall flowing from two sides, on the one hand can be abundant with the organic silicon slurry slag that may be close to inner wall
It mixes and makes organic silicon slurry slag full combustion, the type of flow being on the other hand close to can take away that will adhere to after burning
Grain object, plays the role of being substantially reduced the first Inner Wall of Combustion Chamber carbon distribution.
The present apparatus is helped by realizing to be passed through in the first combustion chamber in such a way that the first Inner Wall of Combustion Chamber takes opposite air-supply
Fire air.
The prior art is to be provided with air outlet at some point of combustion furnace, and this mode is for ordinary comburant
It can satisfy the sufficient condition of burning.However when handling organic silicon slurry slag, inventor's discovery is due to organic silicon slurry slag
It is made of high-boiling components and fine silicon powder, copper powder etc. that flying spot is more than 70 degrees Celsius, is a kind of liquid-solid mixture with mobility,
Such liquid-solid mixture is not easy to be sufficiently mixed with the combustion air by an air outlet in combustion, along with its combustion
It is very high to burn the temperature that reaction needs, therefore forms carbon distribution on the easy insufficient and easy wall in the combustion chamber that burns, goes down for a long time
The heat transfer efficiency of combustion chamber can be reduced, so that burning energy consumption is increasing.First burnup room is passed through combustion air by the present invention
Mode is modified to the opposite mode blown, and on the one hand the air with respect to air-supply can carry out the liquid-solid mixture of organic silicon slurry slag
Stirring promotes the contact area of organic silicon slurry slag and air, on the other hand can carry out air-flow purification to the inner wall of combustion chamber, prevent
Only burning particles are attached on the first Inner Wall of Combustion Chamber.
Compared with prior art, the present invention having the following advantages and benefits：
The present invention realizes the air supply mode of new combustion air by the improvement to furnace interior structure, can be effective
The efficiency of combustion of organic silicon slurry slag is promoted, and the indoor carbon distribution of burning can be removed simultaneously.
