Description

Oil garbage eccentric cleaning system in oil field

Technical field

The utility model belongs to garbage regeneration using production field, is related to garbage disposal more particularly to a kind of oil in oil field Tanaka's oil garbage eccentric cleaning system.

Background technology

Oil field rubbish and contained oil sludge and sand are included in oil extraction in oil field production process is layered on the scene of oil recovery according to environmental requirement The substances such as the ground crude oil of plastic woven cloth and doping sundries.Due to advanced currently without can fully recycle it Technique is recycled, and can only be handled by the methods of scene burial, burning, washing.

Oil Field buries processing mode, to give up since there is some solids rich in mineral oil on these disposed wastes Object, appearance in black it is thick, if untreated, directly bury, not only occupy largely plough, and to surrounding soil, water body, Air will all cause seriously to pollute.It is serious to waste the energy according to live burning disposal mode, and secondary cause underground The pollution of water or soil property.It is individually handled using method for washing and processing, plastic cloth oil-sludge treatment is not clean, oil-containing in mud, water Ingredient is exceeded, and environmental requirement is not achieved, and easily causes the secondary pollution of environment.

In conclusion using above-mentioned processing mode, not only treatment effeciency is low, while secondary dirt can be also caused to environment Dye.Therefore, the processing of oil field oil-containing rubbish is always to perplex a great problem in oil field, and National Environmental Protection Agency receives in relation to new blowdown Take the implementation of method and the increasing of environmentally friendly dynamics, it is more and more stringenter to the inspection of hazardous waste greasy filth.If oil garbage obtains not To dealing carefully with, petroleum-type component part therein can volatilize, and cause the total concentration of the hydrocarbon in the air of oil field relevant range More than national standard, be scattered everywhere and the oil garbage arbitrarily stacked can also polluted surface water and underground water, cause water petrochina Class index is more than seriously national standard.Therefore it takes measures to deal carefully with these oil garbages and has seemed very urgent, it is necessary to Harmless treatment is carried out to it, promotes comprehensive utilization of energy.

Description of the drawings

It is required in being described below to embodiment in order to illustrate more clearly of the technical solution of the utility model embodiment The attached drawing used is briefly described, it should be apparent that, the accompanying drawings in the following description is some embodiments of the utility model, For those of ordinary skill in the art, without having to pay creative labor, it can also be obtained according to these attached drawings Obtain other attached drawings.

Fig. 1 is the structure diagram of oil garbage eccentric cleaning system in the oil field that embodiment 1 provides.

Specific embodiment

It is below in conjunction with the accompanying drawings and real in order to be more clearly understood that the above-mentioned purpose of the utility model, feature and advantage Example is applied to be described further the utility model.It should be noted that in the absence of conflict, embodiments herein and reality Applying the feature in example can be combined with each other.

Many details are elaborated in the following description in order to fully understand the utility model, still, this practicality Novel to implement using different from other modes described here, therefore, the utility model is not limited to be described below The limitation of the specific embodiment of specification.

Embodiment 1, as shown in Figure 1, the utility model is provided containing rubbish eccentric cleaning system in a kind of oil field, from figure In as can be seen that the utility model in key equipment setting and each equipment between connection relation, be merely given as one Simply illustrative figure, below specifically once, the concrete composition of the cleaning system, including sludge-tank, vibrating screen, thick wash pool, pressure Filter stacks pond, fine purifiation pond seperator and oil water tank；Its sludge-tank be then for holding oil field rubbish, used by oscillating screen in Preliminary Separation by vibration is carried out to oil field rubbish, thick wash pool is then for the not passable particle separated in vibrating screen What rubbish was slightly washed, filter press is then for carrying out squeezing processing to the rubbish after slightly washing, and stacks pond, fine purifiation pond, separation Machine and oil water tank can be illustrated in the following course of work.

This system and each component are illustrated below by the course of work of the system,

Step 1：Scalping separation (just separation)：Oil field rubbish with grab bucket from sludge-tank is captured, is put on vibrating screen, It is Separation by vibration to carry out just separation；

Step 2：Slightly wash separation；Can not thick wash pool, Chi Zhong be transported to loading machine by grain size rubbish after sieve sieve is taken Water temperature is held to 50 DEG C or so；

Step 3：Squeeze separation；The rubbish after slightly washing is grabbed with grab bucket, drier oil point and moisture are squeezed in filter press, this Process is except liquid rate is up to more than 80%；

Step 4：It crushes；Rubbish after press filtration is crushed by sliding chute transportation to double-roll crusher, oil-containing it is up to standard It is transported to and stacks pond, not up to standard enters fine purifiation pond.

Step 5：Except sticking is washed；Filter press is rinsed with heating power (cycle) and crusher, the mixed liquor after flushing are pumped to essence Wash pool；

Step 6：Fine purifiation detaches；Sieve is transported to its samming of fine purifiation pond in the form of pumping etc. by object and ties up in step 2 It holds at 85 DEG C or so；

Step 7：Salvage separation；Floating refuse sundries colter in fine purifiation pond is salvaged after machine salvaging drains and is sent to stacking Pond；

Step 8：Precipitation separation；Mixed liquor after salvaging carries out sedimentation separation in case pond.Oil-water fluid after sedimentation separation Mixture is pumped into seperator, and the solids such as dregs after sedimentation separation are transported to sludge-tank by screw conveyor；

Step 9：It centrifuges；Oil water mixture after separation is pumped into oil water tank, Solid Conveying and Melting to sludge-tank.

It can be seen that from above step：The first grab bucket is provided between sludge-tank and vibrating screen, vibrating screen is with slightly washing Loading machine is provided between pond, the second grab bucket is provided between thick wash pool and filter press, is set successively between filter press and stacking pond Chute and double-roll crusher are equipped with, filter press, crusher and conveyer belt, fine purifiation are disposed between filter press and fine purifiation pond Pears knife is provided between pond and stacking pond and salvages machine, and screw conveyor, seperator and oil are provided between seperator and sludge-tank It is connected and set by pipeline between water pot, be provided with delivery pump on the pipeline, connected between vibrating screen and fine purifiation pond by pipeline Setting is connect, delivery pump is provided on the pipeline.

For above description, the first grab bucket and the second grab bucket can use one, and two work are completed in a grab bucket, Such setting is also for saving cost；Above, filter press, the crusher of many places description are also same group used.

It needs herein illustratively, a component described above does not come out shown in the figure.

The above descriptions are merely preferred embodiments of the present invention, is not to make other forms to the utility model Limitation, any person skilled in the art is changed or is modified as possibly also with the technology contents of the disclosure above equivalent The equivalent embodiment of variation is applied to other fields, but every without departing from the content of the technical scheme of the utility model, according to this reality Any simple modification, equivalent variations and the remodeling made with novel technical spirit to above example, it is new to still fall within this practicality The protection domain of type technical solution.
