Description
Technical field:
The utility model relates to oily, the mud discharging device of air supporting, receipts of sewage slurry tank in the oil recovery field, a kind of oil field, particularly a kind of air supporting, oily, the regular eddy flow mud discharging device of the receipts of floating continuously.
Technical background:
The oil field is developed since dropping into,
The one, the slurry tank deoiling effect is relatively poor.Along with the oil field is further developed, oil droplet emulsification degree uprises in the sewage, and settlement separate efficient is reduced; On the other hand, slurry tank top sump oil can not in time be discharged, and partly sump oil strengthens the slurry tank intractability along with coming the water-soluble sewage of going into.
The 2nd, spoil disposal operation time length, complex steps, management difficulty are big.At present, the spoil disposal method of sewage plant mainly contains simple and easy spoil disposal, static pressure perforated pipe spoil disposal, three kinds of methods of negative pressure mud exhauster spoil disposal except that artificial spoil disposal.Simple and easy spoil disposal needs regular stoppage in transit emptying slurry tank, is applicable to the situation that sludge quantity is few.When sludge quantity was big, mud can not in time be got rid of, and is bigger to the water quality impact after treatment facility and the processing; Not only pipeline is many, installation is complicated for the perforated pipe spoil disposal, the workload frequent, switch valve of intersecting is big, and every group of mud exhauster arranged irregular, water conservancy condition difference is bigger, sludge discharge effects is poor, and negative pressure mud exhauster complex process, investment is high, moisture percentage in sewage sludge is high, sludge quantity is big, and management difficulty is big.In addition, the dosing deficiency, medicament is incompatible and can not timely and effective spoil disposal also be the major reason that causes two heavy jar poor processing effect.Because two heavy jar mud can not effectively be discharged, and have seriously influenced treatment effect.
Owing to above reason, cause slurry tank to go out water unstable, often the water outlet oil-containing exceeds standard, and silt content is big, makes follow-up strainer seriously polluted, can not recover by back flushing, with the passing of time then causes filtrate harden inefficacy, poor filtration effect and constantly change problem such as filtrate.Seriously influenced ordinary production.
The utility model content:
In order to solve the problem that exists in the background technology, the utility model provides a kind of oily(waste)water sedimentation treatment unit, this oily(waste)water sedimentation treatment unit not only satisfies receives oil continuously, and has in the sewage jar under the situation of a lot of columns and other obstacles, still silt particle can be got rid of.
By the following technical solutions of the present utility model: this oily(waste)water sedimentation treatment unit comprises natural subsidence jar and coagulant precipitation jar, it is characterized in that: multinomial pump of the external gas-liquid of natural subsidence jar one side and water-supply pipe; The multinomial pump of gas-liquid is connected with the molten gas releasing device of connection; The oil-collecting device that floats connects fuel tank, connects by oil pipe and receives oil pump I; Eddy flow mud discharging device I connects the sludge pump of natural subsidence jar opposite side, and flow sludge discharge device I is connected by newel with unsteady oil-collecting device I; Mixing tank connects the settling section that the associating water injection allocator is positioned at the coagulant precipitation jar; Mixing tank is connected by newel with unsteady oil-collecting device II, and water jet standpipe is positioned at the oblique below of oil-collecting device II of floating, and the oil-collecting device II opposite side that floats connects buffer oil tank, and buffer oil tank connects receives oil pump II; Sludge pump II and water jet standpipe homonymy are positioned at outside the coagulant precipitation jar, are connected in associating water injection allocator below.
The beneficial effects of the utility model: this oily(waste)water sedimentation treatment unit adopt above-mentioned technology solved crude oil recovery liquid level control difficult, reclaim not thoroughly, cause crude oil to condense to become the problem of ageing oil to solve the difficult problem of sewage jar spoil disposal simultaneously.This patent makes full use of the water power of system and receives oil, spoil disposal, saved facility investment, float receive that oil is effective, spoil disposal is thorough, simple to operate, advantage that labour intensity is low.
