Abstract
An incinerator special for organic silicone waste slag slurry is combined by a combustion chamber and a smoke processing device. The smoke processing device is connected by a high-temperature dust remover, a waste heat boiler, a quench tower, a falling film absorber, a scouring tower, an acid separator, an alkaline washing tower, a demister, a smoke discharging fan, a chimney sequence pipeline in sequence. By the device, the organic silicone waste slag slurry can be processed properly, and can not pollute the surrounding environment, and the environment can be protected, in addition, the incinerator can recover slag (containing 15% of copper), steam and 31% of hydrochloric acid, and has obvious economical benefits.
Description
Technical field
The utility model 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 and washes with water and the hydrolysis process processing, 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 utility model overcomes above-mentioned deficiency just, provide a kind of organic silicon waste residue slurry special-purpose incinerator, 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 contain the dedusting of silica dust employing hot precipitator in the flue gas of back, 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 had 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, be introduced into the hot precipitator ash disposal, flue gas enters waste heat boiler and reclaims heat then, and flue gas is reduced to about 200 ℃, then enters quench tower, flue gas behind cooling and the absorption hydrochloric acid enters 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 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 that reclaims behind the hydrochloric acid enters 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 utility model is made 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 by pipeline, by the burner heating rotary kiln primary zone of lighting a fire automatically, the interior temperature of kiln is slowly raise, the combustion air of normal temperature is sent into the revolution cellar for storing things by the oxygenating blower fan, organic silicon waste residue slurry adds agitator tank, through nitrogen pressure, carry inflow revolution cellar for storing things to burn by pipeline, revolution cellar for storing things flue-gas temperature is at 500-800 ℃, and lime-ash is discharged by bottom, revolution cellar for storing things ash hoist, and the flue gas that goes out the revolution cellar for storing things is in the secondary combustion chamber decomposition of further heating, in stove, be heated to and carry out thermal decomposition more than 1100 ℃, after reaching time of staying of 2 seconds, destroy by fire and leave body of heater after clearance reaches 99.99%, enter 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.
By 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.
