Abstract
The invention discloses an incinerator special for organosilicon waste residue slurry. The incinerator consists of a combustion chamber and a flue gas treatment device, wherein the flue gas treatment device consists of a high-temperature dust remover, a waste heat boiler, a quench tower, a falling film absorber, a pickling tower, an acid separator, an alkaline tower, a demister, a smoke exhaust fan and a chimney connected through a pipeline in turn. Due to the device, the organosilicon waste residue slurry is well treated and does not pollute neighboring environment, and the problem of environment friendliness is solved. In addition, slag (containing 15 percent of copper), steam and 31 percent of hydrochloric acid can be recovered, and the incinerator has obvious economic benefits.
Description
Technical field
The present invention relates to the special-purpose incinerator that the processing waste residue slurry in a kind of organosilicon process units is used.
Background technology
The waste residue slurry that produces during organosilicon is produced is the effluent of technology scrubbing tower wet dedusting, is the liquid-solid mixture that higher organic oxosilane of boiling point and the dust below 5 microns form.This liquid-solid mixture is placed on the long-pending piece of free settling in the storage tank, contacts with air and can reaction produce HCL gas.After burning, liquid-solid mixture can produce a large amount of silica dusts.
At present, organic silicon waste residue slurry is still with washing and hydrolysis process and handles, and has used for many years, produces to contain HCL waste water in a large number, and waste residue slurry and air haptoreaction produce HCL gas, and surrounding enviroment are brought severe contamination.
Summary of the invention
The present invention overcomes above-mentioned deficiency just, provides a kind of organic silicon waste residue slurry special-purpose incinerator, and main innovation is to handle organic silicon waste residue slurry with the burning principle; Solved the long-pending piece problem of waste residue slurry sedimentation; Burn and to contain silica dust in the flue gas of back and adopt the hot precipitator dedusting, solved waste heat boiler because of containing the dust blockage problem in the flue gas, and can reclaim slag (containing 15% bronze medal) after burning; Can recovered steam; Can reclaim 31% hydrochloric acid, not only solve environmental issue, also have tangible economic benefit.
It specifically is to implement like this: the special-purpose incinerator of organic silicon waste residue slurry; By combustion chamber and flue gas processing device combination, it is characterized in that flue gas processing device is connected by hot precipitator, waste heat boiler, quench tower, falling-film absorber, pickling tower, acid separator, caustic wash tower, demister, smoke exhaust fan, chimney order pipeline successively.
Flue gas after burning is introduced into the hot precipitator ash disposal, and flue gas gets into waste heat boiler and reclaims heat then; Flue gas is reduced to about 200 ℃, then gets into quench tower, the flue gas behind cooling and the absorption hydrochloric acid gets into falling-film absorber again; Absorb remaining HCL gas in the flue gas, in falling-film absorber, concentration of hydrochloric acid is about at 31% o'clock; Discharger is delivered to factory's salt acid storage tank and is stored; The flue gas that falling-film absorber comes out is further removed the HCL in the flue gas through the pickling tower, and acid separator is removed the drop in the flue gas again, and the flue gas behind the recovery hydrochloric acid gets into caustic wash tower, absorbs with alkali and removes the Cl of remaining HCL gas and minute quantity
2, flue gas up to standard after demister and smoke exhaust fan from smoke stack emission.
Combustion chamber of the present invention is made up of revolution primary zone, cellar for storing things and secondary combustion chamber, and described rotary kiln primary zone is heated by burner, is equipped with the agitator tank of organic silicon waste residue slurry on primary zone, the revolution cellar for storing things inlet pipeline, and the bottom is equipped with ash hoist.
Diesel oil is transported to burner through pipeline, by the burner heating rotary kiln primary zone of lighting a fire automatically, makes that temperature slowly raises in the kiln; The combustion air of normal temperature is sent into the revolution cellar for storing things by the oxygenating blower fan, and organic silicon waste residue slurry adds agitator tank, through nitrogen pressure; Carry inflow revolution cellar for storing things to burn through pipeline, revolution is stored flue-gas temperature at 500-800 ℃, and lime-ash is discharged by bottom, revolution cellar for storing things ash hoist; The flue gas that goes out the revolution cellar for storing things is heated in stove and carries out thermal decomposition more than 1100 ℃ in the secondary combustion chamber decomposition of further heating, reach time of staying of 2 seconds after; Destroy by fire and leave body of heater after clearance reaches 99.99%, get into the flue gas processing device of postorder.
The lime-ash that discharge at the revolution cellar for storing things mainly contains silica flour and copper powder, and the dust that hot precipitator is discharged mainly contains the SiO2 dust, and factory can further utilize.
Through this device, organic silicon waste residue slurry is dealt carefully with, and is pollution-free to surrounding enviroment, solved environmental issue, can also reclaim slag (containing 15% bronze medal), steam and 31% hydrochloric acid in addition, has tangible economic benefit.
Description of drawings
Fig. 1 is a structural representation of the present invention.
The specific embodiment
The special-purpose incinerator of organic silicon waste residue slurry is by combustion chamber and flue gas processing device combination.
The combustion chamber is made up of with secondary combustion chamber 5 primary zone 2, revolution cellar for storing things, and rotary kiln primary zone 2 is equipped with the agitator tank 1 of organic silicon waste residue slurry by burner 3 heating on primary zone, revolution cellar for storing things 2 inlet pipelines, and the bottom is equipped with ash hoist 4.
Flue gas processing device is connected by hot precipitator 6, waste heat boiler 7, quench tower 8, falling-film absorber 9, pickling tower 10, acid separator 11, caustic wash tower 12, demister 13, smoke exhaust fan 15, chimney 14 order pipelines successively.
Burner 3 heating rotary kiln primary zones 2, the organic waste residues slurry is delivered to agitator tank 1, is transported to rotary kiln 2 after the nitrogen pressure and burns; Rotary kiln 2 incineration temperature 500-800 ℃, burn the back lime-ash and discharge from ash hoist 4, flue gas gets into secondary combustion chamber 5 second-time burnings to 1100 ℃; High-temperature flue gas gets into hot precipitator 6 dedustings, and the flue gas after the dedusting gets into waste heat boiler 7 and reclaims heat, and flue-gas temperature drops to 250 ℃ and gets into graphite quench tower 8; Flue gas is cooled to get into the HCL that graphite falling film absorber 9 reclaims in the flue gas about 60 ℃, and flue gas gets into pickling tower 10, further removes the HCL in the flue gas; Flue gas gets into acid separator 11, removes the drop in the flue gas, and flue gas gets into caustic wash tower 12; In with flue gas in HCL, flue gas entering demister 13 up to standard enters 14 chimneys through 15 smoke exhaust fans again.
