Description
Technical field
The present invention relates to environmental energy environmental technology field, more particularly to a kind of greasy filth pyrolysis continuous feeding device.
Background technology
China's oily sludge annual production is huge, and the way of production mainly has three kinds：Produced during crude oil production, crude oil
Produce and produced in sewage from oil refinery treatment plant in production and course of conveying.Wherein during oil extraction, greasy filth yield is
The 0.5%~1% of crude output, State Statistics Bureau's numerical monitor, crude oil in China exploitation total amount is 2.1 × 10 within 20148Ton, oil
Mud yield is about 2,000,000 tons or so, and many oil fields of China come into exploitation latter stage, and greasy filth produces ratio will be bigger.
Oily sludge oil content is general between 20%~50%, moisture content typically between 10%~90%, if without processing with
Meaning discharge, a large amount of arable lands is not only taken up, and great harm can be produced to soil, water and air.Because greasy filth contains largely
Crude oil, not recovered random discharge is also a kind of waste to the energy.Therefore, no matter consider from environmental angle, or from resource
Considered using angle, be required for a kind of advanced technology to carry out innoxious and recycling processing to it.
The pyrolysis of oily sludge anoxybiotic, which produces oil, gas, the technique of charcoal, has it advanced so that the organic matter in greasy filth is whole
Processing, reclaims oil product, realizes innoxious and recycling final disposal, but in actual production process, because greasy filth viscosity is big,
Poor fluidity, common rubbish or the feed system of municipal sludge can not be conveyed to greasy filth.Therefore, one kind can the company of realization
Continuous charging, it is ensured that the induction system of the closed anoxybiotic of fill process is urgently developed.
The content of the invention
In order to solve the above-mentioned problems in the prior art, the present invention proposes a kind of greasy filth pyrolysis continuous feed dress
Put, this device can realize continuous feed of the highly viscous oily sludge in pyrolytic process, and realize high-pressure delivery, measure defeated
Send and anoxybiotic closed conveying so that oily sludge can be delivered at the top of revolving bed, and control by measuring the processing of revolving bed
Amount, while realizing the zero-emission of the hypertoxic gas such as bioxin in pyrolytic process, this equipment is environmentally friendly, reliable, efficient, controllable, fits
Close large-scale promotion.
A kind of greasy filth pyrolysis continuous feeding device disclosed by the invention has：
Storage bin, storage bin has inlet and outlet；
Preload screw, preload screw has entrance and outlet, the entrance of preload screw and the outlet of feed bin, precompressed spiral shell
Revolve side and motor is set；
Bidirectional ram pump, bidirectional ram pump has first entrance, second entrance and first outlet, second outlet, two-way column
The two entrances of plug pump are connected to the first feed pipe and the second feed pipe, and two outlets of bidirectional ram pump are connected to
The outlet of first discharge nozzle and the second discharge nozzle, the first feed pipe and the second feed pipe by feeding house steward and preload screw connects
It is logical, the first reversal valve is set between the first feed pipe, the second feed pipe and charging house steward, and the first discharge nozzle and the second discharge nozzle connect
Discharge header pipe is connect, the second reversal valve is set between the first discharge nozzle, the second discharge nozzle and discharge header pipe.
Further, arch breaking apparatus is provided with storage bin, prevents greasy filth from forming cavity before preload screw is entered.
Further, storage bin bottom, which is set, has the gradient so that greasy filth enters preload screw one end.
Further, irreversibly delivered on the direction of preload screw from the inlet to the outlet, power is provided by motor, by turning
Speed realizes the once metering to greasy filth, and greasy filth carries out primary compression in preload screw, discharges air, it is ensured that greasy filth is in anoxybiotic
Conveyed under state.
Further, piston is connected by bidirectional ram pump by connecting rod with hydraulic cylinder, and bidirectional ram pump power resources are in liquid
Cylinder pressure, is realized by connecting rod and moved back and forth, the unidirectional of greasy filth, high pressure, closed conveying are realized in reciprocatory movement, and complete
Secondary measurement, to reduce once metering and the error of secondary measurement, in specific implementation process, preload screw rotating speed and two-way column
The piston reciprocating frequency for filling in pump is corresponding, while the pyrolysis rate of correspondence pyrolysis furnace apparatus, and then realize up to production.
Further, the first reversal valve selectively communicates with charging house steward and the first feed pipe or the second feed pipe.
Further, the second reversal valve selectively communicates with discharge header pipe and the first discharge nozzle or the second discharge nozzle.
Further, discharge header pipe is connected with pyrolysis installation.
Further, the first reversal valve is changed with the second reversal valve when the piston of bidirectional ram pump changes the direction of motion
To.
Said apparatus is comprised the steps of during operation：
Greasy filth enters preload screw in storage bin after arch breaking apparatus broken arch, and greasy filth realizes compacting in preload screw,
Greasy filth charging house steward is drained into certain pressure.
First reversal valve coordinates the direction of motion of bidirectional ram pump with the second reversal valve and commutated, in the first feed tube
When, plunger is moved right, while the second discharge nozzle outwards discharges；Conversely, when plunger is to left movement, the first reversal valve and second
Reversal valve commutates simultaneously, and greasy filth is on the right side of second charging aperture suction bidirectional ram pump, and simultaneously bi-directionally greasy filth passes through on the left of plunger pump
First discharge nozzle discharges；So go round and begin again, realize that greasy filth is unidirectional, high pressure, closed conveying.
Except meet the first reversal valve, the commutation of the second reversal valve with addition to bidirectional ram pump matching back and forth, preload screw rotating speed
Bidirectional ram pump reciprocating frequence is met simultaneously, preload screw should carry out speed change rotation if necessary；Preload screw conveying capacity Q can basis
Pyrolytic process actual treatment amount is designed, by determining pitch S, helical blade diameter D, speed of screw shaft N and material
Fill factor ψ, according to formula Q=47D2SN ψ are calculated.For example, heap density big situation big in greasy filth viscosity
Under, ψ values can take 0.1.Plunger pump discharge can be calculated according to the volume of bidirectional ram pump with reciprocal time, in detail below
Cold test is substantially carried out in the embodiment of embodiment coordinates preload screw to provide empirical value.
By using above-mentioned technical proposal, following many beneficial effects are achieved：
(1) technique is simple, cost is low, simple to operate, stable and reliable operation；
(2) unidirectional, the continuous conveying of high viscosity greasy filth can be achieved, is greasy filth while ensureing anoxybiotic, high pressure long distance delivery
Follow-up pyrolysis processing provide ensure；
(3) greasy filth metering is realized, error of the greasy filth caused by viscosity is bonded on metering device greatly is eliminated.
