Accompanying drawing explanation
Fig. 1 is the structural representation of drilling sludge processing system.
Fig. 2 is the flow chart of drilling sludge processing method.
Detailed description of the invention
The present invention will be further described with specific embodiment below in conjunction with the accompanying drawings.
Fig. 1 is the structural representation of drilling sludge processing system.
As it is shown in figure 1, drilling sludge processing system includes: sludge dewatering equipment 10, first carries unit 51, mud buffering chamber
20, second conveyor group 52, horizontal rotary dehydrator the 30, the 3rd conveying unit 53, Rotation error the 40, the 4th carry unit
54 and conveying arrangement.
The feeding mouth of the discharging opening of sludge dewatering equipment 10 and the first conveying unit 51 connects.The feeding mouth of mud buffering chamber 20
It is connected with the discharging opening of the first conveying unit 51；The discharging opening of mud buffering chamber 20 connects with the feeding mouth of second conveyor group 52
Connect.Horizontal rotary is dried the feeding mouth of 30 and is connected with the discharging opening of second conveyor group 52；The discharging of horizontal rotary dehydrator 30
Mouth is connected with the feeding mouth of the 3rd conveying unit 53.The discharging of the discharging opening of Rotation error 40 and the 3rd conveying unit 53 is even
Connect；The feeding mouth of the discharging opening of Rotation error 40 and the 4th conveying unit 54 connects.Conveying arrangement receives the 4th conveyer
The discharging of group 54.
First conveying unit 51 and second conveyor group 52 are Shaftless screw conveyors.3rd conveying unit 53 is according to reality
Need to use segmentation structure for conveying, be made up of two Shaftless screw conveyors 53-1,53-2.4th conveying unit 54 is spiral transferring
Send machine.Conveying arrangement is dolly.
Sludge dewatering equipment 10 can be moving plate spiral dewaterer or filter press dewaterer, and mud after dehydration is aqueous is
70-80%, dewatered sludge is delivered to mud buffering chamber 20 by Shaftless screw conveyor 51.Sludge outlet at sludge dewatering equipment 10 sets
Sludge bucket, the bottom of bucket is the import of Shaftless screw conveyor.Mud in mud buffering chamber 20 is defeated by shaftless screw
Send machine 52, mud is delivered to horizontal rotary dehydrator 30.
Setting flight in horizontal rotary dehydrator 30, for being taken up by mud, after dehydrator rotates, mud falls from above,
Add the contact surface of mud and high-temperature flue gas, enhance the effect of heat transfer, mass transfer, improve the efficiency of drying；In dehydrator
If crushing mechanism, it is used for crushing agglomerating clod, it is to avoid " the eggshell effect " of outer dry endogenous dampness occurs.The thermal source of sludge dryer is
The high-temperature flue gas that rear portion sludge incineration produces.
When horizontal rotary dehydrator 30 is installed, its centrage is horizontal by certain angle, and it installs gradient is 2%；Run
Time rotary speed be: 0-4.5r/min.The mud of aqueous 70-80% is sent into rotary dryer from kiln hood by Shaftless screw conveyor
In, taking up through flight, fall, conduct heat with high-temperature flue gas, moisture content progressively evaporates；Under the rotary motion tilting cylinder, drying
Mud finally enters sludge bucket from kiln tail；High-temperature flue gas enters dehydrator from kiln tail, carries out heat exchange with mud in cylinder, will
Water in mud is heated into water vapour, discharges from kiln hood.High-temperature flue gas inlet temperature is
600-700 DEG C, exit gas temperature is: 70-110 DEG C.Such as acid gas-containing in flue gas, exhaust gas temperature necessarily be greater than
Dew point.
Horizontal rotary dehydrator 30 has flue gas processing device.Flue gas processing device includes: electrostatic precipitator 31, air-introduced machine
32 and chimney 33.Electrostatic precipitator 31 is entered, at high-pressure electrostatic from horizontal rotary dehydrator 30 aqueous ash-laden gas out
Under effect, flue dust, water in flue gas are all separated, and clean flue gas is after air-introduced machine 32, enter air from chimney 33.
The kiln hood loading hopper of Rotation error 40 is delivered to by conveying worm 53, through spiral from dehydrator mud out
Rotation error 40 sent into by conveyer.Mud evaporates through moisture in Rotation error 40, dry, sump oil burning, then
Process clean body refuse and enter hopper from kiln tail, send dolly to pull away through conveying worm 54 after cooling.
The rotary kiln of Rotation error 40 is steel cylinder structure, inner lining as thermal insulation material, refractory material.During installation wherein
Heart line is horizontal by certain angle, and it installs gradient is 2%；During operation, rotary speed is: 0.2-2.5r/min；During stop
Between: 40～60min, mud volumetric efficiency: Fd=3.7%.Kiln tail at rotary kiln arranges Oil-combustion combusting machine, for rotary kiln
Interior mud and kiln body heat, and during operation, mud is in high-temperature flue gas, flame, the common effect of burner hearth high-temperature refractory
Under, it is achieved from moisture evaporation, be dried, sump oil burning, burn.High-temperature flue gas and mud reverse movement in stove, heat transfer efficiency is more
High.The flue gas discharged is discharged into sludge dryer from kiln hood, and rotary kiln exhaust gas temperature is at 600-700 DEG C.Needed for sludge incineration
Air, by aerator from kiln tail send into.
Rotation error 40 has Oil-combustion combusting machine 41.Due to drillng operation in the wild, and mobility is big, and it assists combustion
Material can only be with oil, so configure oil storage tank 43 and domestic oil tank 42 must to Oil-combustion combusting machine 41.
Sludge dewatering equipment 10, conveyer, mud buffering chamber 20；Horizontal rotary dehydrator 30 and Rotation error 40 points
It is not arranged on three integrated steel-structure platforms.So that equipment transition.
Fig. 2 is the flow chart of drilling sludge processing method.
As in figure 2 it is shown, drilling sludge process method step is as follows:
Step A, mud enter sludge dewatering equipment from mud storage tank under the drive of pump, and mud is carried out by sludge dewatering equipment 10
Processed, the mud after dehydration is aqueous for 70-80%.
Mud after step B, dehydration is delivered to mud buffering chamber 20 by Shaftless screw conveyor 51 and temporarily deposits.
Mud in step C, mud buffering chamber 20 is delivered to horizontal rotary dehydrator 30 by Shaftless screw conveyor 52 and enters
Row is dried, and material is dried to 40% by first moisture 70%.
The flue gas that step C-1, horizontal rotary dehydrator 30 produce is after cleaner unit purifies, air-introduced machine after introducing chimney
Discharge.
Step D, dry after mud be delivered to Rotation error 40 and burn, material moisture from 40% dry to
10%.
When not oil-containing in mud, the incineration temperature of Rotation error 40 is 600 DEG C-700 DEG C；When oil-containing in mud
Time, the incineration temperature improving Rotation error 40 is 650 DEG C-950 DEG C.
Step E, burn clean mud through conveying worm 54, deliver to cart transport to next process.
