Description
Technical field
The present invention relates to disposition of solid waste process field more particularly to a kind of oily sludge Oil Recovery and it is granulated dry
Makeup is set.
Background technique
With the fast development of petroleum industry and the increasingly promotion of environment protectment protection, oily sludge is classified as by China
Solid hazardous waste (HW08).The oily sludge generated in oiliness sewage treatment and oil extraction process and its processing disposition are
Through becoming an increasingly serious problem.Oily sludge contains multiple pollutant matter and oil content range generally 5% ~ 45%, if
It will cause the wasting of resources without being effectively treated, and seriously pollute environment, or even be detrimental to health.
China has put into a large amount of research fundings in terms of disposal of oily sludge disposition, carries out technology and equipment R&D work,
And develop solvent extraction treatment process, demulsification treatment process, quenched-mechanically decoupled technique, incineration treatment technology, pyrolysis processing
The processing techniques such as technique, burying treatment process and curing process, but due to processing cost and environmental requirement etc., China
Disposal of oily sludge ability need to be improved.
Mud granulizing is to coexist for solid and liquid and the dispersion based on solid phase, utilizes the self-adhesion of dispersion
Property (or outer adding additives) simultaneously keeps solid portion micro- by the pressures mode such as gravity, centrifugal force, mechanical force, extruding, air flow impulse
Grain is mutually bonded, increases the particle for forming specific shape and granularity.In recent years, multiplicity is also presented in disposal of oily sludge treatment approach
Change trend, especially minimizing, stabilisation, innoxious and recycling treatment disposal technology are development trend, and treated contains greasy dirt
Mud can be used as construction material (such as roadbed paving, brickmaking, slope protection and build a dam), production fuel, production gum filler and adsorption material
Material etc., but above-mentioned minimizing, stabilisation, innoxious and recycling treatment treatment approach need to carry out oily sludge oil removing, de-
It is granulated again after water process.
Chinese patent CN108558164A discloses a kind of dustproof and anti-explosion oily sludge granulation drying equipment, including is granulated cabin
It with desiccation cabin, is granulated in cabin and is horizontally installed with several rollers, motor is installed out of my cabin, offers feed inlet, desiccation cabin above cabin
Inside is equipped with a rotary shaft, heating shallow bid and heating deep bid is mounted alternately in rotary shaft, the lower end in desiccation cabin offers out
Material mouth is equipped with thermometer, pressure gauge and combustable gas concentration detection table on side wall.The patent pertains only to the granulation of sludge and does
Change, oil removing, the dehydration of oily sludge are not directed to, therefore also do not have Oil Recovery technique；
Chinese patent CN206069677U discloses a kind of city domestic sewage processing plant excess sludge drying particles device, knot
Structure is simple, accelerates sludge drying by interlayer and cavity structure, is designed by structure, optimize mud granule motion path, improves
Desiccation effect；But the patent does not set agitating device, sludge, which easily agglomerates, in granulation process causes device to block；
Chinese patent CN101913750A discloses one kind and can safely and effectively handle the wet mud of sewage plant, is convenient for
Sludge following resourceization development and utilization device and method, the device include screw extrusion granule-forming machine, spouted fluidized bed and
Dewatered sludge particle feed bin forms, and the sludge shaped granule after preliminarily dried flows into fluidized bed bottom from spouted bed lower openings
Portion, another part hot gas medium enters fluidized bed from fluidized wind air inlet and carries out depth drying to mud granule, after dry
Mud granule moves upward to fluidized bed layer surface from fluidized-bed bottom, and last overflow goes out fluidized bed, into dewatered sludge
Grain storehouse；Patent process object is sewage treatment plant excess sludge, is not suitable for disposal of oily sludge disposition.
To sum up, for existing oily sludge granulating technique and the immature problem of equipment, need to develop novel oily sludge without
Evilization and recycling prilling granulator.

3.4, which enter plate and frame filter press 7.1, carries out filters pressing, and the oil product recycled in reserve 4 collects reuse by the discharge of oil outlet 4.1, dirty
Waste water is further processed rear discharge up to standard by the discharge of the first water outlet 5.1 in pool 5, and plate and frame filter press 7.1 exists in filters pressing area 7
Stretching filters pressing is carried out under the action of first motor 6 and the second belt 7.4, first motor 6 is connect with PLC control system, is realized just
Turn with reversion alternately；Sludge dehydrated sludge moisture content under the effect of plate and frame filter press 7.1 is 50% or so, dewatered
Sludge enters stirring area 9 by 7 bottom right of filters pressing area, and filtrate then enters the filtrate collecting zone 7.2 of 7 bottom left of filters pressing area, with
Afterwards from the discharge of the second water outlet 7.3 be further processed it is up to standard after discharge, open the second motor 11 and drive third belt 9.2 and the
Two agitating shaft 9.1.1 work, and the dewatered sludge that moisture content is 50% or so in stirring area 9 stirs equal through the second stirring blade 9.1.2
Even, the second motor 11 drives the 4th belt 8.3 and pelletizer 8.1 to work, by sludge conveyer belt 8.2 and elevator pump by stirring area 9
Interior sludge is sent to pelletizer 8.1, and setting pelletizer grain diameter is 0.5 cm, and it is 0.5 cm's that partial size is obtained after being granulated
Granule sludge, is collected to granulomere 10, and subsequent granule sludge is packed for use by particle outlet 10.1.
Pelletizer 8.1 in the present apparatus with rapid condensation effect can be commercially available, such as: Changzhou creates association's machine
The RL type pelletizer of tool Co., Ltd；The pelletizer 8.1 can manufacture spherical particle or ellipsoidal particle, particle size adjustment range
For 0.1 ~ 1.0 cm；
