The present invention relates to a kind of petroleum hydrocarbon contaminated soil hot wash complete set of equipments cleaning technique technique, steps are as follows: 1. transports: this equipment selects different pretreatments equipment according to Different field by 6 skid mounted equipments, 1 pretreatment unit composition, pretreatment unit.6 skid mounted equipments are respectively 2 water tanks sled, 2 stirring water tank sleds, 1 greasy filth water process sled, 1 boiler skid, and equipment size is made by container requirements, it is only necessary to which 2-3 17.5 meters of semitrailers can transport, at low cost.2. installation: principle is simple, and occupied area is small.3. operation: primary pretreatment screening, a dosing, a clean cycle complete discharging technology, and the cleaning is run under the conditions of 60 DEG C~70 DEG C, and low energy consumption and ejected wash water can be recycled for multiple times, and reagent cost and the wasting of resources can be greatly reduced.4. discharging: the soil washed out can be used for filling, and isolated oil is recycled by refinery again.5. equipment is dismantled: it is quick detachable, on main equipment without influence, it is convenient to replace construction site.
Description
Technical field
The present invention relates to environmental protection and petroleum hydrocarbon technical field of soil remediation, more particularly to untreated for many years contain volume
It is micro- useless to disposal site and related greasy dirt disposal field to knit the greasy filth such as bag, iron block, stone pond.
Background technique
Oil-sludge treatment is a kind of technology for protecting environment, soil remediation.Greasy filth, that is, oily sludge is oil field and petrochemical industry
A kind of high volatile being made of minerals, mineral oil and water for being generated in production process, highly viscous organic hazardous object.If not
Add any discharge of processing, it will serious harm is caused to local environment.Containing the TPH of high-content in greasy filth, such as returned
It receives, using its heat, can be used as the energy.Therefore the processing to greasy filth, it can solve the serious ring that petrochemical industry is faced
Border pollution problem had not only protected environment but also had realized the recycling of the discarded energy.
The drilling cuttings greasy filth of oil extraction, crude oil storage tank tank bottom oil accumulation mud, ground sludge, aging greasy filth etc., in the market generally
Equipment treated greasy filth, greasy filth amount is 5-30% after processing, and national related disposal standard is not achieved in low efficiency, while
It is unable to catch up with the generation speed of greasy filth, untreated greasy filth is piled into mountain, and pollutes the environment.
Summary of the invention
This purpose invented in fact is to overcome difficult point in the prior art, and it is complete to provide a kind of petroleum hydrocarbon contaminated soil hot wash
Equipment cleaning technique technique.
Technical solution of the present invention:
In pretreatment unit of the invention is primarily directed to the greasy filth of different situations, it is only necessary to pre-process together, for greasy filth pond
It is very big with the packed equal more humidity of oil-containing, construction requirement can be met by one of screening and filtering technique of minute-pressure rotary tank, such as
Fruit is more dry, the greasy filth of similar soil, is needed by particle screen selecting, required in terms of granularity mainly with greasy filth water at
The feed needs of the horizontal spiral discharge sedimentation centrifuge of sled are managed to design.
It stirs water tank and prizes dischargeable capacity 15m3, Horizontal double-spiral blade stirring mode is taken, water tank prizes dischargeable capacity 28m
3, Piping Centrifugal Pumps and Aeration fan are installed in equipment, horizontal spiral discharge sedimentation centrifugation is installed in greasy filth water process sled
Machine, per hour treatment effeciency 15-25m3/h, complete equipment are heated by steam, the recoverable boiler water reuse of condensed water or when clear
Wash water is used, and needs steam to heat and keep the temperature wherein stirring water tank sled and water tank sled.The greasy filth pre-processed passes through some equipment
Device (pump, conveyer belt, screw conveyor) enter stirring water tank sled 1 and stirring water tank sled 2, stirring water tank sled 1 be added medicament and
It is maintained at 60 DEG C~70 DEG C of constant temperature and constantly stirs, mixing time is 40 points~60 minutes, is passed through after being stirred to react completely
Sand pump etc. is sent to greasy filth water process sled and is separated by solid-liquid separation, and the solid oil content of separation come out is lower than 2%, reaches country
For dangerous waste discharge standard, direct emission, the oil-water mixture separated are carried out by its internal mounted screw conveyor
Water tank sled 1 is then entered by dredge pump, its internal lower layer's overwhelming majority ejected wash water is passed through water tank by the static some time
The Piping Centrifugal Pumps carried in sled 1 is drawn back to water tank sled 2, while when stirring water tank sled 1 and rejoining new material by water storage
Ejected wash water in case sled 2 refills stirring water tank sled 1.When stirring water tank sled 1 is separated by solid-liquid separation, stirring water tank sled
2 carry out material reaction stirring, after stirring water tank sled 1 is disposed, by valve transfer, will react in stirring water tank sled 2
The material finished is sent to greasy filth water process sled by sand pump, realizes the continuity of greasy filth disposal system.For water tank sled 1
It is emitted into other equipment by the Piping Centrifugal Pumps of water tank sled 1 when reaching certain amount by the oil slick inside constantly accumulated,
It is recycled and is utilized again.
Beneficial effects of the present invention
Cleaning process of the present invention is simple, and cleaning effect is good, and the hot wash suitable for various petroleum hydrocarbon contaminated soils is washed.The present invention uses
Surface-active desorption principle and physics are heat-treated the mode of stirring to handle by petroleum hydrocarbon contaminated soil, on the one hand can reduce
The usage amount of medicament is on the other hand lower relative to pyrolysis temperature currently on the market.Ejected wash water is recycled for multiple times, can be greatly
Saved construction cost, on the other hand, biggish for greasy filth pond humidity, this cleaning process is non-pyrolytic comparable, most critical
A bit, this cleaning process cost is far below pyrolysis cost, while the oil that cleaning is isolated can recycle.
Specific construction mode
The greasy filth pond of the accumulation many years in 701 oil field of Karamay, Xinjiang, ten, soil, the country of response now, is badly in need of repairing, specific to locate
Steps are as follows for reason:
(1) according to site requirement, area is put to equipment and carries out preventing blending hardened ground processing and pre-treatment plant and finished product windrow
The construction of field puts installation containing water, electricity and gas construction and equipment.
(2) soil to be processed at scene crush and Screening Treatment, screening particle are less than 3mm, use equipment for powder
Broken machine and sand sieving machine.
(3) by forklift will pretreatment it is good after soil shovel and convey material mouth into belt feeder, by belt conveyor by its point
It is not delivered in stirring water tank.
(4) ejected wash water and medicament is added to be stirred to react, it is completely reacted after mixed liquor through sleeping in greasy filth water process sled
Formula screw settling centrifuge is separated by solid-liquid separation.
(5) solid discharge described in is to rickyard, and oil slick is then in centralized collection to one big storage tank.
The soil of centrifugation discharge is detected in batches, testing result is shown in Table 1
