C, the bulk sandstone of deposition is intermittently discharged from slag-drip opening, after recycling the reaction flowed out by gas vent
Waste gas, the sludge after product exit extraction, until complete sludge wet-type oxidation degradation processing, wherein, sludge is taken out
Output is highly controlled with the normal level of liquid being able to maintain that in reactor.
During reaction, it is back to after preferably a part of waste gas is pressurizeed again in reactor, by another part
Waste gas is used to preheat fresh sludge or gaseous oxidant or discharged after directly carrying out vent gas treatment.
With reference to specific embodiment, the utility model is described in further detail.
Integrated treatment reactor shown in Fig. 1 is used for sludge oxidative degradation, needed liquid level first before reactor start-up
It is promoted to more than product exit.Enter by air and/or oxygen pressing to 5MPa and from gas access and first gas distributor
Uniform bubbling is carried out in the zoneofoxidation of reactor, drives current to be circulated in inside reactor when bubble moves upwards.
The start-up temperature of the heating mantle maintenance reaction device of reactor external insulation is at 250 DEG C.Heat medium can use electricity,
Oil or steam, when using oil or steam, medium inlet and outlet are correspondingly set on muff.Reactor heating only needs
Carried out within a period of time that device has just started, liberated heat is enough to maintain the normal of whole reactor after sludge starts reaction
Operation.
The sludge that water content is 80~90% is disperseed to be passed through from the sludge disperser of sludge import, sludge sinks to bottom
Pyrohydrolysis area simultaneously starts to mix in the presence of magnetic stirrer, hydrolyzed, and sludge character changes, by not having consolidating for mobility
Body is changed into the slurry with certain fluidity, then enters zoneofoxidation and air and/or oxygen with current at the top in pyrohydrolysis area
Gas haptoreaction simultaneously releases substantial amounts of reaction heat.Temperature measuring unit is set on reactor to monitor the temperature in reactor as 250 DEG C,
Stop external heat after stable reaction, the reaction heat maintenance reaction released using reaction is carried out.
Reacted mud is extracted out from product exit, and extracted amount is to maintain normal level of liquid to be highly controlled.Mud with
Gas flows up between guide shell and zoneofoxidation side wall, and when reaching expansion open height, heavier mud granule ploughs under water conservancy diversion
Cylinder inside and from guide shell bottom outflow reenter circulation.Slurries gas content outside guide shell is high, density is low and to
Upper flowing；Slurries gas content inside guide shell is low, density is high and moves downward, and maintains the self-loopa of whole reaction system
Journey.Cyclic process adds residence time of the sludge in zoneofoxidation, and the organic matter in sludge obtains fully degraded.Reacting
Cheng Zhong, the bulk sandstone for being deposited on bottom is intermittently discharged from the slag-drip opening of reactor bottom.
Reacted waste gas (including unreacted air, oxygen, vapor and gas of reaction generation) flows upwards out liquid
Face enters the gas compartment with reactor top, passes through gas vent outflow reactor after the demister of top.A part is useless
Gas is forced into slightly above system pressure and returns to reactor, another part from recyclegas entrance again under gas circulation pumping action
Waste gas enters downstream and can pass through heat exchanger and is used to preheat fresh sludge or oxidant, can also be directly over vent gas treatment dress
Postpone discharge.
In summary, integrated treatment reactor of the present utility model incorporates sludge hot water in sludge wet oxidation process
Solution and two processes of sludge wet oxidation, realize that sludge wet oxidation is handled in same reactor, be effectively improved dirt
The economy of mud wet oxidation equipment, it is reasonable in design and workable；The utility model is reduced to feed sludge water content
Limit value, from the dewatered sludge (80% water content) without mobility to mobility sludge (90% water content)
It is applicable, is directly fed without pre-processing；Unreacted oxygen is included in the waste gas that reactor comes out, waste gas passes through extraneous gas
Circulation is reentered in reactor, is improved the residence time of gas in the reactor, is improved sludge degradation efficiency, also improve
The utilization rate of oxygen.
The utility model is not limited to foregoing embodiment.The utility model expands to any in this specification
The new feature of middle disclosure or any new combination, and disclose any new method or process the step of or any new group
Close.
