Abstract
The invention discloses a method for accelerating the microwave pyrolytic process of oily sludge by pyrolyzing residue thereof, which comprises the following steps: carrying out microwave pyrolysis on the oily sludge or sludge under the condition of nitrogenization, controlling the temperature to be 700-850 DEG C and performing microwave incineration for 5-15min to obtain solid microwave residue; mixing the microwave residue with the oily sludge or the sludge evenly, wherein the weight of the microwave residue is 0.5-5% of the oily sludge or the sludge; and then carrying out microwave pyrolysis on the oily sludge or the sludge under the condition of nitrogenization. The invention can accelerate the pyrolytic process of the oily sludge or the sludge, shorten the pyrolytic time, effectively save the energy consumption of the oily sludge or the sludge processing, and improve the processing efficiency; the residue after the microwave pyrolysis can be recycled; and the method of the invention has low cost, is economical and can be popularized and utilized.
Description
Technical field
The present invention relates to a kind of method of greasy dirt microwave-heating, relate in particular to and utilize cheap pyrolyzing residue to accelerate the method for greasy dirt microwave-heating process, realized greasy filth, perhaps energy-conservation, the raising microwave-heating efficient of mud microwave-heating.
Background technology
The pyrolysis of greasy filth or mud generally adopts traditional method to carry out the indirect heating pyrolysis.This method exists energy consumption height, easy coking and recovering liquid oil substances to contain higher shortcomings such as aromatics.Because there is the double effect of pyrolysis and microwave catalysis in microwave-heating.Therefore, adopt microwave technology that greasy filth, pyrolyzing sludge are become a kind of new pyrolytic technique.But, owing to lack enough materials that helps microwave absorption in greasy filth or the mud, cause the process of microwave-heating greasy filth or mud very long, even in for a long time, all can not reach temperature to greasy filth, pyrolyzing sludge, processing efficiency is low, energy consumption is big especially, can not realize the minimizing and the recycling treatment of greasy filth, mud.Usually, people as microwave absorptions, adopt gac to add process of active carbon, promote the microwave-heating process, and cost is higher.Based on this, be badly in need of to adopt a kind of new cheap microwave absorption, add greasy filth to, perhaps in the mud,, realize greasy filth, perhaps energy-conservation, the method that improves microwave-heating efficient of mud microwave-heating to accelerate its microwave-heating process speed.
Summary of the invention
The objective of the invention is to solve the problems of the prior art, provide a kind of pyrolyzing residue that utilizes of cheapness to accelerate the method for greasy dirt microwave-heating process.
For achieving the above object, technical scheme of the present invention is, greasy filth or mud are carried out microwave-heating filling under the nitrogen condition, is controlled at 700 ℃-850 ℃ then and carries out microwave and burned 5-15 minute, obtains solid microwave residue; Then this microwave residue is mixed according to the 0.5-5% of greasy filth or mud weight and greasy filth or mud, again greasy filth or mud are carried out microwave-heating filling under the nitrogen condition.Like this, the greasy filth or the mud of interpolation microwave residue will obtain effective microwave-heating.
The inventive method can be accelerated the pyrolytic process of greasy filth or mud, shortens pyrolysis time, has saved the energy consumption of greasy filth or sludge treatment effectively, has improved processing efficiency, and the residue behind the microwave-heating is reusable edible also; And the inventive method cost is low, and economy can extensively be promoted the use of.
Embodiment
Embodiment 1:
At first greasy filth carries out microwave-heating filling under the nitrogen condition, is controlled at 700 ℃ then and carries out microwave and burned 15 minutes, obtains the microwave residue; Secondly, in the greasy filth of water ratio 70%, add the greasy filth microwave incineration residue of greasy filth quality 1.0%, foreshorten to about 2 hours filling the time that can make microwave-heating under the nitrogen condition.If increase the addition to 5% of residue, the greasy filth microwave-heating time of water ratio 70% was shortened in 5 seconds, the microwave-heating process of greasy filth is disappeared substantially, directly enter into the microwave burning process, obtain residue at last.This residue also can proportionally be mixed into to exercise and use with greasy filth.
Embodiment 2:
Mud carries out microwave-heating filling under the nitrogen condition, be controlled at 850 ℃ then and carry out microwave and burned 5 minutes, obtains the microwave residue; In the mud of water ratio 70%, add the mud microwave incineration residue of sludge quality 1.0%, foreshorten to about 3 hours filling the time that can make microwave-heating under the nitrogen condition.If increase about the addition to 4.5% of residue, shortened in 30 minutes the mud microwave-heating time of water ratio 70%; Behind about 30 minutes microwave-heating, the greasy filth temperature continues to raise, and enters into the microwave burning process; Through burning, obtain the microwave residue.This microwave residue also can proportionally be mixed into to exercise and use with greasy filth.
Embodiment 3:
In the greasy filth of water ratio 70%, add the greasy filth microwave incineration residue that 1.0% embodiment 1 obtains, foreshorten to about 2 hours filling the time that can make its microwave-heating under the nitrogen condition equally.If increase the addition to 5% of residue, the greasy filth microwave-heating time of water ratio 70% was shortened in 5 seconds, the microwave-heating process of greasy filth is disappeared substantially, directly enter into the microwave burning process, obtain residue at last.This residue equally also can proportionally be mixed into to exercise and use with greasy filth.
Embodiment 4:
In the mud of water ratio 70%, add the mud microwave incineration residue that 1.0% embodiment 2 obtains, foreshorten to about 3 hours filling the time that can make its microwave-heating under the nitrogen condition equally.If increase about the addition to 4.5% of residue, shortened in 30 minutes the mud microwave-heating time of water ratio 70%; Behind about 30 minutes microwave-heating, the greasy filth temperature continues to raise, and enters into the microwave burning process; Through burning, obtain the microwave residue.This microwave residue equally also can proportionally be mixed into to exercise and use with greasy filth.
