Multi-stage spiral separation and filter device and application method.
Background technology
Country is honest, and to push the dynamic whole society energy saving, improves efficiency of energy utilization, protection and improves environment, promotes economical
Social All-round, Coordinated and Sustainable Development.But the processing of some emissions is not reached requirement in many industries at present, than
It is especially in the construction of underground engineering such as in construction industry, there are a large amount of mud and particulate matter without detailed-oriented separation and mistake
Filter is just discharged；And in sewage disposal process, centralized collection, fractional precipitation and additive treating are mainly taken at present
Mode；In addition to this, in the pumpingh well in oil field, the crude oil extracted out from stratum contains sand grains or impurity, and crude oil is caused to reach
Less than production requirement.
It is at present hydrocyclone separation technology silt particle technology for most common technology is separated by solid-liquid separation, particularly as being to use cyclone
It is detached using the principle of centrifugal sedimentation, specific operation principle is：When two-phase (solid-liquid) (or three-phase) to be separated is mixed
After conjunction liquid is tangentially entered in cyclone with certain pressure from cyclone periphery, it is rapid to generate the strong rotational shear of strong Three-Dimensional Elliptic
Stream movement, it is poor (or density contrast) since there is granularities between coarse granule (or heavy phase) and fine grained (or light phase), it is subject to
Centrifugal force, centripetal buoyancy, fluid drag etc. are of different sizes, are acted on by centrifugal sedimentation, and most crude particle (or heavy phase) is through eddy flow
Device underflow opening is discharged, and most of fine grained (or light phase) is discharged by overflow pipe, to achieve the purpose that separation classification.
Cyclone is a kind of device generating rotary motion using Fluid pressure.When slurry enters eddy flow with certain speed
Device is forced to make rotary motion after encountering cyclone wall.Since suffered centrifugal force is different, suffered by the solid coarse granule in slurry
Centrifugal force it is big, hydraulic resistance can be overcome to be moved to wall, and under the collective effect of its own gravity, along wall downward spiral
Movement, thin and small particle and most of water and close to wall do not do rotary motion then because suffered centrifugal force is small with slurry.
Under the promotion being subsequently fed, slurry continues downward and rotary motion, and then coarse granule continues to periphery concentration, and fine particle
Central area is then rested on, grain diameter is increasing from center to wall, forms hierarchal arrangement.As slurry is from cyclone
Columnar part flows to conical section, and mobile section is smaller and smaller, starches and is shunk under compressing in outer layer material, contains a large amount of fine particles
Internal layer slurry have to change direction, then move upwards, form inward eddy, be discharged from overflow pipe, become overflow, and coarse
Particle then continues to move along wall downward spiral, forms contour stealth, is finally discharged by underflow opening, becomes sediment.
It, can be to a certain extent in mud, sewage and crude oil although existing cyclone may be implemented to be separated by solid-liquid separation
Particulate matter detached, but initial gross separation can only be carried out, the emission of substance of processing can not reach environmental protection, energy-efficient want
It asks.In addition to this, the cyclone device of existing ordinary construction is when handling some thick liquids such as mud, due to granule density mistake
Big or liquid viscosity is excessively high, and cyclone underflow pipe clogging frequent occurrence in work causes production that cannot carry out, and underflow
When pipe blocks, phenomena such as larger solid phase particles of grain size and excessively high effluent concentration will occur in overflow port, reduce eddy flow
The separative efficiency of device.
For the measure for taking technically feasible, reasonable in economy and environment and society that can bear, it is desirable to provide one
Kind can reduce consumption, reduce loss and pollutant emission, prevention waste, effectively and reasonably be filled using the separating and filtering of the energy
It sets.
