Description

Low energy dynamic water purification system and water purification method

The present invention relates to a water purification system and a water purification method, which are devices and methods for separating and decomposing suspended pollutants in a fluid from industrial fluids such as wastewater, and in more detail, by using the inertia of a dynamic fluid passing through a separate spiral tube It relates to a low-energy dynamic water purification system and a water purification method that separates contaminated water into turbid water and purified water to purify contaminated water with low energy.

In general, a water purifying device that seeks to purify contaminated water to obtain purified water is concentrated by sinking microscopic granular substances that cause it to become cloudy by being dispersed and mixed in a large amount of liquid such as washing water, factory drainage, and water and sewage. Separated and removed with dirty soil (장치: thick sludge), on the other hand, there was a device to continuously recover the supernatant that does not contain granules, and the purification method is to take the granules dispersed in the liquid. In this case, a flocculation agent is added to the suspension as a pre-treatment to accelerate the sinking, and the flocculant is often flocculated by flocculation and sedimentation. At this time, the flocculant adsorbs the particles floating in the suspension, It had the effect of accelerating sedimentation by coagulating with each other and facilitating filtration while facilitating sedimentation.

The purification method of sewage by the simple sedimentation method as described above, even in the supernatant except for sludge, turbid water mixed with fine foreign matter and clearer purified water (淨水 or fresh water) It is classified as (淸水), and there have been developed a number of devices and methods for separating and purifying such contaminated water into purified water, and Korea Patent Publication No. 1991, No. 7808 (released May 30, 1991) As described in ), a water purifying device having an active container in which a filter medium (= filter) and pulverized rocks are stacked has been developed, and a filter as disclosed in Utility Model No. 21012 (published on December 18, 1992) The water purifier installed was installed, and most of them used filters for water purification in the early days.In the registered utility model No. 289069 (announced on September 13, 2002), in addition to a solids removal filter, a photocatalytic cracker was further provided. The device has been known, and in addition, as disclosed in Patent Publication No. 102726 (published on September 28, 2006), even a technology that enables replacement of a filter using a filter in a water purification system using a water filter is developed. As it has been, most of the water purifiers are equipped with various filters such as a belt press filter, a centrifugal filter, and a filter using a separator for purification.

Due to this, one or more separate filters are installed in the transport pipe, and if these filters are contaminated by foreign substances, a separate means is required for replacement or cleaning. However, it has had a number of problems, such as water purification efficiency is rapidly lowered when the filter is contaminated.

In order to solve this problem, the development of significant field applications with abundant analytical research separates the basis of the conceptual method and the flow of heterogeneous materials into separate streams based on dean vortices (= vortex plurals). A unique device has been built, and its flow elements or fluids have a gravitationally significant mass as a result of non-uniform density or dynamic viscosity, and exhibit uniform density and viscosity in dynamic flow from fluid flow. This can be achieved without compromising the ability to successfully separate suspended or neutral buoyancy materials.

Recently, considerable research has been published on micro-fluidity technologies using Dean vortices as a means to condense and separate non-uniform particles in a fluid, and mechanisms using forces against hydrodynamic flow and centripetal forces. There are no doubts about the importance and value of these new technologies in applications where channel flow and cellular-sized particles are manipulated by low-energy processors.

Typical examples of such implementations are Republic of Korea Patent Publication No. 75568 (published on June 29, 2016), U.S. Patents 8,807,879 B2 and 8,208,138 B2. The implementation of this micro-channel features a linearly increasing radius of a rectangular flow channel and a circular helix, as shown in FIG. 1, the plane of this spiral flow being orthogonal to the force of gravity, orthogonal gravity ( The orthogonal gravitational force exerts collapsing pressure on the Dean vortex across the short axis of Dean forces.

The present invention was developed to solve the above-mentioned problems of the prior art, and the present invention first deviated from the water purifiers that mostly used filters in the present invention. Low energy dynamic water purification system and water purification method that enables low energy particle separation to be applied to a fluid transport device that uses a variety of filter media with maintenance and support requirements, consumes a lot of energy, and is applied to industries and applications where continuous operation is restricted The present invention has been completed with the subject to be solved in the invention in order to provide.

In addition, this new change in the implementation of Dean Vortices aims to be implemented in industrial applications, with full size being used to successfully classify and separate at rates of 10 tonnes per hour or more.

Also, although not separately described, other objects within a range that can be inferred in consideration of the specific contents and claims and drawings for carrying out the following invention in detail that describe the low energy dynamic water purification system and water purification method of the present invention It is included in the overall solution of the present invention.

As a specific means for solving the problems of the present invention, in the present invention, in the low energy dynamic water purification system and the water purification method, the low energy dynamic water purification system of the present invention includes suspended particles (=floating particles in the water) and neutral floating particles (=underwater) The fluid with floating particles) is pumped and separated and discharged from the end of the flow channel into relatively turbid water and relatively clear water by a eddy vortex through a spiral flow channel, so that purification can be performed without using a separate filter medium. It is characterized in that the surface formed by the spiral flow channel through which the fluid is Dean flows is configured to form a spiral parallel to the gravity vector, thereby minimizing the cancellation of the Dean vortex by gravity.

The helical flow channel is configured to minimize the interference of the Dean flow of the fluid due to gravity by the centripetal force vector by relatively densely implementing the spacing between the lower channels than the spacing between the upper channels in the helical shape. It consists of a tube and presses the tube on both sides of the spiral flow channel, so that the cutting plate of the spiral flow channel is pressurized and variable in an elliptical shape so that a compression plate is installed.

In the spiral flow channel, several spiral flow channel tubes made of a single piece with a compression plate interposed therebetween are continuously connected, but the turbid water separated and discharged from the individual spiral flow channels is separately discharged and collected to collect water. The separated discharged water is made to be supplied to the input channel of a single helical flow channel connected to each other, or a pair of helical flow channels are connected by a crossover flow channel from the inside, and separated discharge from a pair of helical flow channels The purified water discharged from the pair of helical flow channels while being discharged and collected separately may be supplied to the input channels of a pair of helical flow channels connected to each other.

The low energy dynamic water purification method of the present invention is characterized in that the hydrodynamic system is non-uniform to the force of gravity (viscosity and density) by orienting the flow path in a plane parallel to gravity, so that the force of gravity is neutralized using centripetal force. As a water purification method using Dean vortex to support the separation of suspended particles in a dynamic fluid flow that can show

a. Placing the main flow circuit so that it is in a plane parallel to the force of gravity,

b. Manipulating the centripetal force vector in each increment of the arc length around the main flow circuit to compensate for the force of gravity, which includes:

i. Means for constructing a circular acceleration component of the centripetal force to compensate for the gravitational component of the force acting to disrupt the separation of the Dean vortices such that the assigned gravity and the resulting centripetal force are consistent throughout the entire toroidal circumference; Construct the radius of the main flow circuit in each increment of arc length to create an annular helical flow channel, and the appropriate radius is calculated using the total a (acceleration) equation obtained for r (annular radius), where θ is the rotation angle between r and horizontal,

r = v2/[(total a) + (sin θ * g)]

Ii. Alternatively, the fluid flow velocity to compensate for the gravitational acceleration component of the force acting to disrupt the separation of the Dean vortex, and therefore as a means of controlling the acceleration component of the centripetal force and supporting the Dean vortex to provide an invariant resulting total centripetal force. Achieved by changing the acceleration component of the centripetal force vector in one or both of the two ways (i, ii), which constitutes the cross-sectional area in each increment of the arc length of the circular or helical flow channel of the volumetric flow rate. It is characterized in that it comprises the above steps.

At the edges of the rectangular cross-section flow channel with a width-to-height ratio sufficient to satisfy the start-up parameters to improve the initial formation of the Dean vortex in the flow channel subjected to centripetal acceleration and to form the Dean vortex. Due to the limited cross-sectional area of the two half circles to propagate the Dean vortex or turbulent discontinuity, as an integer method of extending the persistence of the Dean vortex over a wider range of flow velocities than a typical circular flow,

a. Compress the circular channel in a uniform manner controlled at a fixed fluid flow rate until the formation of Dean vortices is detected,

b. The compression height is recorded when the state of Dean vortex is achieved,

c. The process may be characterized by repeating for each combination of fluid viscosity, density and dynamic effects of the solute fluid system.

Also, in contrast to the established practice of branching the flow at the midpoint of the main flow, along the zero net force line between the Dean and centripetal forces of the hydrodynamic forces, the particles are in a position to find equilibrium. As a water purification method that enables selection of particles for inclusion, regardless of

It may also be characterized by locating a tunable edge in flow, collecting two output streams for analysis, and adjusting or harmonizing the edge angle and position until the necessary separation is achieved.

According to the specific means for solving the above-described problem, the low energy dynamic water purification system and the water purification method of the present invention are implemented with a typical Dean vortex so that the Dean vortex flow rate is parallel to the gravity vector so as to improve the effect of gravity on the fluid and particles. By forming the main axis of the spiral implementation, it is possible to eliminate the adverse effect of gravity applied to the particles floating at a specific point in the fluid channel through the implementation of the preferred Dean vortex.

Along with this, the water purification system of the present invention is characterized by the dean flow that occurs when orthogonal din flow is significantly affected by gravity and the surface flow characteristics of density and viscosity are not uniform due to the dynamic effect of the fluid system on suspended particles. It is the biggest feature in removing distortion.

In addition, the present invention is a new device capable of inexpensively forming a high-performance boundary layer, and mechanically changing a cross-sectional shape of a flexible tube from a circular shape to an elliptical shape to provide a flow channel optimized for the delivery of Dean vortices.

Force application can be applied statically or dynamically, and can be used to optimize the application of hydrodynamic and centripetal forces to selectively collect suspended or neutral suspended particles in a fluid with variable flow rates, etc. The expected effect is a great invention.

The present invention decomposes suspended particles, which are contaminants in the fluid, into the fluid by separating the fluid into turbid water and purified water by using the inertia of the fluid passing through a spiral tube (= channel) instead of a conventional filter medium, such as wastewater. It relates to a low-energy dynamic water purification system and a water purification method that enables the purification of polluted water to be made remarkably, and to be described in more detail with the drawings below, the accompanying drawings can easily describe the content and scope of the technical idea of the present invention. It is only an example for explanation, and is not limited thereto, and the terms used are also for describing the embodiment in detail and should not be interpreted as being limited to the term.

The water purification system provided by the present invention is a Dean flow analysis applied to be used to supplement the Reynolds number (36) analysis of flow in an annular (=spiral) system composed of a relatively small diameter flow channel 40. (Dean Flow analysis) (Fig. 3) evolution and adaptation.

As shown in Figures 1 and 2, the current state of implementation is that floating and/or neutral buoyancy particles and fluids under the influence of gravity can no longer be considered to have uniform viscosity and density, and therefore Dean vortex Create a device that does not address the problem of dynamic flow in a fluid engineering system that enables gravity distortion and collapse. The first is that these devices provide a Dean vortex in a plane orthogonal to gravity, allowing deformation of the collapse of the Dean vortex leading to that deformation. The second is that the shape of the channels used in these devices allows distortion at the corners. 110 is a distribution of velocity vector rings exemplifying the slow boundary layer flow, typically with respect to the walls of the straight horizontal conduit and the straight section of the horizontal circular flow channel; 116 is circular rolling eddy currents created in horizontal segment 114 by distribution of velocity as shown by vectors 112 caused by flow adhesion in the boundary layer near the walls of the conduit. Is an example of

The compressed non-uniform distribution of compressed velocity vector rings 120 and velocity vectors 122 in the horizontal section 124 of the curve of the flow channel is a result of the centripetal force of the horizontal curved conduit. The cloud vortices 126 bending in the flow are the result of centripetal forces introduced by the curve acceleration in the conduit, while still showing the flow distribution 122 as a result of the boundary layer adhesion.

The evolution of the distorted horizontal flow 131 to a stable distortion 132 is a Dean number characterized by a ratio of the diameter of the conduit 40 and the radius of curvature of the circular or helical path 41 ( unity) and is predicted by the number of Deans when there is a sufficient flow velocity.

The formation of Dean vortices orthogonal to flow 134 is the result of the contrasting effects of centripetal force 140 and hydrodynamic force 142. In the current practice, this phenomenon is used to isolate and collect floating or neutral buoyancy particles when the hydrodynamic force is balanced by the relative density of a particular particle and the centripetal force of hydrodynamic drag or resistance. It was used to generate micro-channel membraneless filtering. Importantly, in the current implementation, as shown in the diagram of FIG. 1, the gravity 136 is orthogonal to the main flow vector 134 and orthogonal to the centripetal force 140 vectors and the hydrodynamic force vector 142. will be. Therefore, gravity is compressing the short radius of Dean vortices. However, the micro-channel implementation of the current practice of membrane free filtering relies on the uniform viscosity and density of a fluid system comprising suspended particles or neutral buoyancy particles and fluids to limit the effect of gravity on propagating Dean vortices.

The gravity in these orientations 131, 132, 133 is not countered by the flow vector 134 or centripetal force 140. As such, the centripetal and hydrodynamic forces of the two counter-rotating Dean vortices are compressed by a system of fluid and suspended particles or neutral buoyancy particles unless the complex system of fluid and particles moves with the fluidity of the homogeneous fluid. This is the general orientation of similar devices found in both research and application today, and thus the associated forces that can be manipulated to counteract the destructive effects of gravity acting as an important influence on centripetal acceleration and moderate forces of hydrodynamic flow. This does not exist.

This gravitational effect prevented large-scale adoption of dynamic filtering for public and industrial applications. The unique methods detailed in this specification are typically real world empirical analysis of trial and error with analysis support in areas taken as assumptions in Reynolds number 36 and Dean number 34 analysis descriptions. Benefits from The method described herein rotates the main helical or circular flow 134 to operate in the gravitational plane.

This typical operating assumption is that both fluid density 37 and fluid viscosity 38 are constant throughout the flow. This assumption is that Dean flow (34) in the application to particle separation into a limited classification of suspended or neutral buoyancy particles that are not affected by the force of gravity in dynamic flow when captured by the conflicting centripetal force and fluid engineering forces of Dean vortex. ).

This method sacrifices the ability to separate these particles unaffected by gravity in dynamic flow by rotating a circular or helical axis to be coplanar with the gravity vector 136 when captured between centripetal and hydrodynamic forces. The simultaneous application of the fluid with floating or neutral buoyancy particles affected by the force of gravity in dynamic flow, without seaming, extends the previous method of application of Dean vortices in particular.

The technique of this method controls the force of the implementation of Dean vortex to counteract the effect of gravity. The controllable effect is the result of centripetal force and fluid velocity 39, which, in the case of incompressible fluids, can be manipulated directly or indirectly by forming a flow channel of variable cross-sectional area; Therefore, with a constant fluid flow volume, it is possible to directly control the fluid velocity.

Alternatively, the effect of velocity controls centripetal acceleration, which can be realized as angular velocity, a function that actually changes the radius of the circular or helical path 41 to create a toroidal path for a constant velocity of flow. Can be manipulated.

The basis of this method is to reorient the toroidal flow channels 152, 153, 154, 155 to be in a vertical gravitational plane aligned with the gravity vector 136, such that the force of gravity is aligned with the centripetal force vector 140. . Additionally, as the main flow moves around the annular flow, because the Dean vortex is orthogonal to the main flow 134, the gravity vector is orthogonal to the retrograde flow paths of the two opposite rotating Dean vortices 156, 157. When minimally destructive, the main flow vector 134 will be aligned with the gravity vector 136.

In these examples, when the main annular flow 134 vertically rises 157 or descends 156 (angle θ is 0° or 180°) and acts against gravity 157 or gravity 156, the main flow And the forces of gravity combine to push the force of Dean vortices into the main flow up (157) against gravity or down (156) against gravity. Either way, Dean's forces are not forced to collapse. Although the vortices can extend their long axis or bend up or down, the vortices are not pushed to collapse the minor axis or to separate between the two opposite rotating vortices.

At all other points along the toroid flow path where the sine value of θ is non-zero, this method provides the angle θ between the plane perpendicular to the radius and the gravity plane while the flow velocity remains constant. Calculate the radius 68 of the annular flow channels as a function.

The equation for Total Force 72 forms the basis of this method. The centripetal force, when the sine value of θ is 0, the hydrodynamic force 142 driving the Dean vortex as a result of particle separation and the gravity component 136 orthogonal to the long axis or the working axis of the centripetal force 140 It can be varied to be reversed at any angle other than 0° and 180°. In this example, for a given velocity (2.5 m/sec) and total centripetal force (2 g), the vertical component of gravity acting to affect the centripetal force is in equation (74) as it is executed using a specific value (75). By calculating the radius (r) 41, a table 68 of the radius 41 that can be reversed in the plane of interest can be calculated.

While the centripetal force 140 is at a horizontal extreme (theta is 0° or 180°) that cannot be used to reverse the force of gravity 136, the force of gravity goes against or against the force of the main toroid flow 134. Work directly together. If the fluid is not compressible or if the flow channel is not able to deform significantly, the flow velocity 39 is maintained almost independent of the gravitational force pushing or pulling the fluid velocity vector, with minimal effect in elongation of Dean vortex cross flow properties. Have

FIG. 5 includes a table 68 of r values expressed in meters, calculated for a speed of 2.5 m/sec and a continuous net centripetal force of 2 g. As shown in the radius diagram 67, the center of rotation of the toroid 65 is eccentric, from a minimum of 66 to a maximum of 82 as shown in the radius graph illustrating a minimum of about 0.21258 meters to a maximum of about 0.6377 meters. Support radius.

Preferred embodiments of this method are presented in FIGS. 4A-4B in lamination (=overlapping) compression plates 44, 45, 46 and intrinsic device 52 of deformable tubing. The deformable piping in this implementation supports an enhancement that aids in the formation of Dean vortices by creating non-circular flow channels 144 (154, 155, 156, 157). This technique prevents turbulent-induced right angled edges of the rectangular flow channel. Instead, this arrangement is a compression limiting cross that acts to limit the compression of the round deformable flow channel so that it becomes an elliptical flow channel 144 (154, 155, 156, 157) with significant variations between long and short distances. It features an over duct fixture (51). This configuration enhances the onset of Dean vortices and aids its persistence over a wider range of speeds.

As one of the important aspects of the device, as shown in FIG. 4A, stack them in horizontal dimensions between compression plates 44, 45, 46 and flow 49 into another annular configuration 50 having the same radial dimension. It is an optimization of toroidal loops with almost ideal radius dimensions 49 and 50 by making the use of a compression limited crossover duct 51 to route seamlessly.

In addition, the device 53 can move along the path of collision between the opposite Dean forces 140, 142, moveable edge 210 as in FIG. 6 to select a particle collection for inclusion or exclusion. It is implemented as a tunable feature of a dynamic filter using.

The assembled device 52A can consist of any number of stacks 52. As an example, 52A presents an assembly of nine plates that capture four pairs of helical channels 61, 62, 63, and 64, each pair having an optimal radius 75 for a particular channel diameter 40 It is composed of.

Bolts 54 are used to compress the flow channels into optimal oval shapes 144, 154, 155, 156, 157. Typical input fluid channels 43 feed at the required fluid flow rate 39. The dynamic filter and fluid flow rate of each stack (61, 62, 63 or 64) of selected diameter will separate the suspended particles so that they exit through the fluid channels (55, 56, 57 and 58), and the remaining flow channels (47). ) Is free of all suspended particles separated by this configuration.

The cross compression limiting device (=crossover flow channel) 51 in FIG. 4A contributes to connecting the two annular flows of each stack 52, and the stacked cross link flow channels 60 are structures 52A. It contributes to providing a connection between the co-mounted stacks 52 of the furnace.

As shown in FIG. 4B, the flow of the helical toroids is not composed of a pair of two annular flows by connecting two annular flows by a cross-compression restriction device 51, which is a crossover flow channel, as in FIG. 4A. Flow can be implemented to be continuously connected, and at this time, after passing through each of the annular channels through the input channel 43, the purified water discharge channel 47 is connected to the input channel 43 of the next one of the annular channels overlapping adjacently. Contaminant (= turbid water) discharge channel 48 is implemented to be separately collected, and the input channels 43 and discharge channels 47 and 48 of each neighboring annular (=spiral) flow channel are external as shown in FIG. 4B. It is made to change from inside to outside alternately from inside to inside.

In addition, the water purification method using the low energy dynamic water purification system of the present invention will be individually presented below.

<Low energy dynamic first water purification method>

Dynamic fluid flow that allows the hydrodynamic system to exhibit non-uniform characteristics (viscosity and density) with respect to the force of gravity, by orienting the flow path in a plane parallel to gravity, so that the force of gravity is neutralized using centripetal forces. As a method of using Dean vortex to support the separation of suspended particles in fluid flow,

a. Placing the main flow circuit so that it is in a plane parallel to the force of gravity,

b. Manipulating the centripetal force vector in each increment of the arc length around the main flow circuit to compensate for the force of gravity, which includes:

i. Means for constructing a circular acceleration component of the centripetal force to compensate for the gravitational component of the force acting to disrupt the separation of the Dean vortices such that the assigned gravity and the resulting centripetal force are consistent throughout the entire annulus circumference, such as the annular flow channel or Construct the radius of the main flow circuit in each increment of arc length to create an annular helical flow channel, and the appropriate radius is calculated using the total a (acceleration) equation obtained for r (annular radius), where θ is the angle of rotation between r and horizontal:

r = v2/[(total a) + (sin θ * g)]

Ii. Alternatively, as a means of controlling the fluid flow velocity, and hence the centripetal acceleration component, and supporting the Dean vortex to provide an invariant resulting total centripetal force to compensate for the gravitational acceleration component of the force acting to disrupt the separation of the Dean vortex. By changing the acceleration component of the centripetal force vector in one or both of the two schemes (i, ii), which constitute a cross-sectional area in each increment of the arc length of a circular or helical flow channel of constant volume flow rate. The method comprising the step of achieving.

<Low energy dynamic second water purification method>

Dean vortices at the corners of a rectangular cross-section flow channel with a width-to-height ratio large enough to satisfy the start-up parameters to improve the initial formation of the Dean vortices in the flow channel subjected to centripetal acceleration and to form the Dean vortices. Or because of the limited cross-sectional area of the two half circles to propagate turbulent discontinuities, as an integer method of extending the persistence of Dean vortices over a wider range of flow velocities than typical circular flows,

a. Compress the circular channel in a uniform manner controlled at a fixed fluid flow rate until the formation of Dean vortices is detected,

b. The compression height is recorded when the state of Dean vortex is achieved,

c. A method is implemented in which the above process is repeated for each combination of fluid viscosity, density and dynamic effects of the solute fluid system.

<Low energy dynamic third water purification method>

In contrast to the established practice of branching the flow at the midpoint of the main flow, along the zero net force line between the kinetic force and the centripetal force of the hydrodynamic force, it correlates to where the particles can find equilibrium. As a water purification method that enables the selection of particles for inclusion without, the method places the tunable edge in flow, collects two output streams for analysis, and edges until the necessary separation is achieved. A method of adjusting or harmonizing the angle and position is implemented.

According to this low energy dynamic water purification method, fluid channels can be implemented using a continuous fluid flow channel configured to affect a toroidal flow of variable radius to meet the requirements of the first water purification method to compensate for the effect of gravity, , A device in which the fluid channels are uniquely stacked in parallel rows maintaining effective radii, wherein the main flow axis of the annular flow (annular radii) lies in a parallel oriented plane of gravity, the main annular flow channel The shape and radius of will be in accordance with the equation for calculating the annular radius to compensate for the gravitational component of the force acting to disrupt the separation of the Dean vortex and to provide the total centripetal force that supports the Dean vortex.

The circular cross section of the flow channel is compressed to improve the propagation of the eddy vortices in the flow channel by changing the circular cross section, creating a smooth and precise elliptical cross section shape with a neutral ratio between the long and short diameters of the ellipse. The device has a pair of rigid plates (= compression plates) to uniformly compress the circular channels to a predetermined height to form an elliptical shape.

By changing the position according to the present application, the separation of particles is improved by using a movable edge within the flow, the edge is positioned vertically over the main flow by a din force and the edge is positioned so that the movable edge almost diverts the flow. Concentrated particles distributed over a zero line of force between the Dean hydrodynamic force and centripetal force, and reduced from the branch where the two outlet fluid channels meet, so that they can be indexed across the main flow channel with the effect of almost capturing the distributed particles A thin, smooth, or sharp edge that is movable or positioned is extended into the main flow channel that supports the Dean vortices of the particle population.

Expanded by stacking the multiple devices, the inner cross-sectional area of the flow channels of each stacked device is the same, and the effect of the stacking is that of the Dean vortices so that the stabilization of the Dean hydrodynamic forces and centripetal forces drives the particle selection process. It is to extend the duration.

Expanded by stacking the multiple devices, the internal cross-sectional area of the flow channels of each stacked device ranges from large to small, and the selection process discharges the collected particles after each stacking segment and , Then transfer the remaining flow to the small cross-section of the next stack, thereby using the same main flow with the effect of reducing the population of particles and the average size of the remaining particles after each stack segment separation and removal from the continuous flow. This is to enable continuous separation particle collection action performed continuously.
