Abstract
The invention discloses a double-introduction layer tower expanding cavity type separator which can adapt to large production load variation and can not generate a phenomenon that bubbles are generated when high-speed gas-liquid stirring is carried out so that separation can not be carried out under high load. According to the invention, a unique double-introduction mechanism and multi-layer gradually-expanded separation chamber can ensure that even though the flow and physical property of a separation medium are greatly varied, the separator can adapt to the flow and the physical property; and by means of a Coanda effect namely wall-attached flow of fluid on an expanded wall surface, the fluid nearby a boundary deflects outwardly, axial symmetric circulation current with downward periphery and upward center can be naturally generated, thereby overcoming the self-sustained oscillation caused by clash impact of inner current in a pure cylinder chamber and reflect current at the bottom of the pure cylinder chamber. Multiple units of cyclone sedimentation separators can be combined and used, so that the separation space is saved, the separation efficiency is high, operation is stable, and the variable working condition adapting property is good.

Description
Technical field
The invention belongs to the centrifugal cyclone sedimentation-separation technology field of multi-phase ingredients, be suitable for gas-solid phase, liquid-solid phase containing solid particle, the liquid phase medium containing drop carries out efficient separation under the very large operating mode of its changes in flow rate scope.
Background technology
Decanter type and centrifugal rotary streaming separator are the multiphase separator patterns of commercial Application amount maximum.Decanter type relies on gravity to promote sedimentation and the floating of heavy, light phase, needs very large sedimentation face.Centrifugal rotary streaming relies on centrifugal force field to carry out brute force separation, and efficiency is higher.General decanter type separator (tank) often, with the centrifugation of entrance, makes heavy constituent attached to container inner wall sedimentation, light component make progress buoyance lift poly-in to outlet, then by filter, remove particle or the drop of sneaking into.And centrifugal rotary streaming separator is according to the difference of purposes, be often called cyclone separator, hydrocyclone etc.
Common decanter type separator, the heavy phase that contains a large amount of suspensions in its tank inner chamber body, rise heavy phase particle, so its volume is large, efficiency is low and flow can not excess load because the upflow velocity of lightweight phase can not blow.Horizontal sedimentation formula is slightly good, but still can not satisfy the demands.
Centrifugal rotary streaming separator, by means of powerful centrifugal force field, can make light, dense media fast hierarchical, has higher separative efficiency and production capacity.But, due to without the adding of moment of face, to defer under the prerequisite of the moment of momentum theorem, angular velocity of rotation and pressure between each layer of medium are inconsistent, and shearing turbulent flow and the eddy current of generation can make separating effect variation.In the situation that eddy flow is violent, can cause large micelle broken, stir and bear foam or produce emulsification, make medium be difficult to separation; The effect and eddy flow is too gently had no way of.Because tangential flow velocity is that swirl strength is directly proportional in the increase and decrease of flow, therefore generally very narrow corresponding to efficient separated treating capacity scope.
The situation that the load variations such as Oil-gas Separation are large or change field of employment for oil, gas field, often requires treatment facility to have large as far as possible operating flexibility.Adopt cut-out, the input operation of a plurality of equipment parallel connections not only to bother, also increase cost, if working conditions change is too frequent, does not catch up with operation and will be absorbed in failure state.
Summary of the invention
The present invention is just for the above-mentioned deficiency of existing separator, and a kind of brand new creating and action principle more effective " two introduced layer towers expansion cavate separator ", can overcome the deficiency of existing separator technology, greatly promote the variable working condition conformability of separator, and can dwindle significantly the volume of separator.
The invention provides a kind of structure is relatively simple, efficient, treating capacity changes accommodation very greatly, medium physical property strong adaptability, withstand voltage high separator, meet under oil, gas-field exploitation and other occasions, for gas-liquid separation, gas-solid and liquid-solid separated demand.
The innovative technology solution that the present invention takes is:
1. layer tower expanded the separation chamber of cavity structure
The present invention is divided into upper and lower two sections by the interior chamber of rotational flow settlement knockout drum (16), and what its main cyclone section (18) completed the layering of medium and dense media phase relies on flowing of inwall.And the rotational flow settlement section (17) of multilayer expansion, it is emphasis of the present invention, it has the structure of the multilayer expansion cavate as layer tower, by the conical cavity structure of expanding gradually, one section of cylindrical cavity is communicated to the cylindrical cavity of next section of enlarged-diameter, the conical cavity of formation cone post chamber in layer---i.e. one section of expansion is one section of cylindrical cavity of continued access again.The number of plies in cone post chamber is minimum be one deck, does not limit at most, and the diameter of lower one deck cylindrical cavity is greater than last layer, and each chamber all axially connects, and the bottom in last one deck cone post chamber is sealed.
Adopt above-mentioned structure, can play the effect of two aspects:
The first effect is the self adaptation that reaches treating capacity.When flow increases, the switching that binding medium imports, can flow in lower one deck cone post chamber by fast-descending, due to the increase of diameter, can significantly reduce swirl strength, can not stir foam and emulsification, and continue separated and attached wall sedimentation; And if flow continues to increase, medium also can flow in the cone post chamber that lower one deck diameter is larger by fast-descending, then reduces swirl strength, continue separated and attached wall sedimentation, the like.If treating capacity is less, medium just almost completes separation in last layer cone post chamber, then is deposited to cone post chamber below.
The second effect is to make separator working stability.Utilize the wall attachment effect (Coanda effect) of jet, inwall in flaring cone chamber, the axial flow of medium can be along cone chamber wall to extrinsic deflection, thereby avoid the rising discharge currents of light substance phase, produce downward along wall periphery, circulation in the chamber making progress along center, can make separator working stability, avoid as pure cylindrical cavity, in the medium in chamber, stream impacts with the contrajet head-on collision of bottom, causes self-oscillatory severe situation.
2. machine-processed corresponding to two importings of different flow
Separator of the present invention adopts two independently medium inlet and entrance cavities.Under low discharge, blending agent mostly from low discharge entrance (2) by low discharge surge chamber (6), enter and centripetal rotational flow generator (20), carry out strong pre-supination, tangential inflow in rotational flow settlement knockout drum (16) carried out centrifugal and sedimentation separation, because flow is little, the tangential velocity flowing into is limited, swirl strength is also suitable, can not stir and bear foam or produce emulsification.And when treating capacity increases, by outside stream, regulate and control, blending agent passes through large flow surge chamber (4) from the large flow entrance (1) on top mostly, enter in axial rotational flow generator (22) and carry out suitable prewhirling, under spiral, flow to again in rotational flow settlement knockout drum (16) and carry out centrifugal and sedimentation separation, because flow is large, the tangential velocity that spiral enters is still higher, enough cyclonic separation, and the axial flow velocity of spiral flow, can make medium drop to quickly in the cone post chamber that lower one deck diameter is larger, avoid the time to grow and stir raw foam, treating capacity with automatic increase separator.
3. multiunit any parallel connection and parts shares
Separator of the present invention also adopts the topology layout of a plurality of separative elements application in parallel, each rotational flow settlement separative element is by rotational flow settlement knockout drum (16) separately, the prewhirl axial rotational flow generator (22) of large flow blending agent, the prewhirl centripetal rotational flow generator (20) of low discharge blending agent, light substance delivery line (15), the parts such as dense media leadout hole (14) form, axial rotational flow generator (22) is installed on the upper surface of upper spacer (5), upper spacer perforate () is opened in the position that upper spacer (5) covers at axial rotational flow generator (22), centripetal rotational flow generator (20) is contained between upper spacer (5) and median septum (7), median septum is opened median septum perforate (19) in the hollow position place of centripetal rotational flow generator (20) correspondence, axial rotational flow generator (22), centripetal rotational flow generator (20), the perforate of two dividing plates all with rotational flow settlement knockout drum (16) the centering center of circle.Structure like this, the parts such as each rotational flow settlement separative element can common media entrance, outlet, surge chamber, membrane support, and all needn't bear pressure medium, and therefore can save a large amount of material costs and space, the pressure of medium relies on the shell (3) of separator to bear.
The invention has the beneficial effects as follows:
1. can significantly promote the changes in flow rate accommodation of separator, the high efficiency range of separative efficiency is broad, and operating flexibility is large, need to frequently not regulate from outside.
2. in separator, be difficult for stirring raw foam and emulsification, the strong adaptability of separator to medium physical property.
3. drag losses is little, and the treating capacity of unit volume equipment is large.
4. save material, easy to manufacture, can bear high-pressure medium, be adapted to especially the separation of high-pressure oil gas.
