The course of work of the utility model and principle are specifically described below:
The utility model relates to a kind of oily sludge object comprehensive utilization devices, first when the device is to the processing of oily sludge object Oily sludge object is first sent into quenched pre-separation unit, oil product is isolated and is sent into oil tank storage, discharge slurry is sent into separating and dehydrating Unit has centrifugal device in this element, further can deeply remove oil in slurry, and discharge residue is sent into drying unit, into Row dehydration.
Detailed process is as follows:
(1) quenched pre-separation unit: material and air are mixed, device is entered by device middle and lower part, and be arranged one in lower part Fixed number measures mouth, and unmixed uniform liquid continues separation mixing by circulating pump after rear end is mixed into air.Middle and lower part into Material mouth is in a symmetrical arrangement, and enters with tube wall in tangential, and raw material enters high speed rotation after eddy flow section, and hair is arranged at feed inlet Bulb apparatus, air in micro-bubble shape enter device after being mixed into, a large amount of bubbles mixing in a liquid, greatly facilitated medicament with Mixed between material, and in eddy flow section material revolving speed up to 800~2000 turns/min；In high-speed rotation process, medicament It is sufficiently mixed uniformly with raw material.Bubble is promoting medicament and raw material to be uniformly mixed the oleophilic drainage characteristic simultaneously as bubble, Surface can adhered portion oil product, oil product at the top of device, when oil product accumulation is to certain liquid level, passes through at the top of device with bubble floating Overflow port discharger.It is equipped with water outlet in air bearing pars infrasegmentalis, for adjusting liquid level, the water of discharge can be used for raw material tune Match.In overall process, medicament undergoes four mixed processes with raw material altogether: mixing for the first time, feed line road connection medicine Pipeline is added in agent, sucks medicament by the conveying of raw material and air-flow, realizes material mixing；Second of mixing, in device entrance The bubble generator (aerator) of setting, while generating bubble, further mixed material；Third time mixes, material warp Prolong in wall surface tangential inlet high speed rip into device, reaches 1600r/min in eddy flow mixing section liquid revolving speed, and entrance is in symmetrical Arrangement, injection direction is on the contrary, interval successive, material undergo rotation to mix with derotation in the device；4th mixing, is filling Lower part setting circulating pump is set, constantly recycles liquid, so that material is uniformly mixed.
Aqueous 70~95% in the debita spissitudo oily sludge object material；The additive amount of medicament is 0.2~2%；With Parts by weight meter.
(2) separating and dehydrating unit: the slurry from quenched pre-separation unit is sent into two-phase or three-phase supercentrifuge, high 2000~4000r/min of fast centrifugal basket scooter can be further deep by oil product remaining in slurry during high speed centrifugation Degree separation, the solid of output is sent into dryer after centrifugation, and solid is heated to 100 DEG C or so using heat source (high-temperature gas), will Moisture is dried in slag.
Solid aqueous amount≤70% after the centrifugation；Solid oil content≤3% after the centrifugation；The drying unit is sleeping Formula dryer；The heat source is high-temperature flue gas, temperature >=300 DEG C；80 DEG C of the outlet temperature > of the dryer；In dewatering unit Heating temperature is 300~500 DEG C, and reaction pressure is normal pressure.
The specific implementation case of the utility model is as follows:
Oily sludge object: Heilungkiang somewhere greasy filth is used；
Greasy filth is aqueous: 82%, oil-containing: and 10%, containing solid: 8%.
Greasy filth is delivered in cyclone air-flotation machine by Pulp pump, medicament when conveying greasy filth by sucking, and additive amount of medicament is about 0.3%, material prolongs wall surface tangential inlet from device lower part and is sent into, and bubble generator is arranged in inlet, and greasy filth mixes greatly It measures in bubble high speed rip into device, reaches 1500r/min in eddy flow section liquid revolving speed, a large amount of solid particles are due to centrifugation and gravity Double action is mutually separated with oil product, and slag liquid is discharged by bottom slag discharge.And it is equipped with circulator in lower part, it can be realized liquid Body repeatedly recycles, and further increases its treatment effect.A large amount of bubbles and oil product and water ascend into air bearing section, and a large amount of bubbles are rapid It floats, due to the lipophilic-hydrophobic property of bubble, a large amount of oil products bring top air bearing section by bubble, while being added in right amount in air bearing section Flocculant promotes solid particle to be agglomerated into bulky grain, and the solid slag of bulky grain gradually sinks down into eddy flow mixing section, eventually by row Cinder notch discharge.After stratification, oil product is exported by top oil product and is discharged for oil product and water, and water is discharged by middle and upper part water out.Slag (aqueous 73%) enters in the three-phase centrifuge of separating and dehydrating unit slurry, and centrifuge speed reaches 2800r/min, by oil, mud, water Three-phase completes separation, and oil and water are discharged through oil export and water out respectively, and residue is sent into dryer, and dryer is produced with hot-blast stove Hot fume out is heat source, and hot fume temperature is 400~650 DEG C, and hot fume is entered by drying motor spindle, top discharge, drying Solid aqueous rate≤5% afterwards, material reduction rate is up to 90% or more.
It takes or uses for reference prior art and can be realized in the part that do not addressed in aforesaid way.
It should be noted that under the introduction of this specification, any equivalent substitute side made by those skilled in the art Formula or obvious mode of texturing, should be covered by the scope of the present utility model within.
