Description

{Continuous washing flotation, sedimentation, filtration device}

The present invention relates to an apparatus and a method for performing a flocculation and filtration process in which a flotation separation, a precipitation separation and a filtration are performed by a single unit to increase the efficiency of purification while increasing the space efficiency, To a continuous washing flotation, sedimentation, and filtration device.

In general, various treatment methods such as filtration method, sedimentation method, bacterial cleaning method, sterilization method and the like are applied to the treatment methods of sewage, wastewater, early storm sewer, sewage sewage overflow (hereinafter referred to as "sewage" .

On the other hand, in the method of treating the sewage upwardly, a method of removing various foreign substances contained in the sewage is mainly used by using granular filter media which are water-washed in water rather than chemical treatment, or floating filter media located on the water surface.

Sand and ceramics are mainly used as the particulate filter material to be desalinated into the electron water. The granular filter material that is desiccated in the water is treated in such a way that the sewage to be treated in the housing or the treatment tank is processed while passing through the granular filter media from the lower part to the upper part. Since the removing operation for removing the foreign matter remaining between the granular filter media in the completed state requires a separate washing facility, there is a disadvantage that the washing operation is troublesome.

The floating filter media located on the latter surface of the water is a floating filter material having a specific gravity lower than that of water, such as synthetic polymers, and is formed into various porous forms. It floats on the water surface to filter foreign substances contained in sewage rising from the bottom to the top So that the purification efficiency can be improved while minimizing the chemical treatment.

However, in the case of treating the sewage water using the above-mentioned conventional floating filter material, since the washing operation for removing the foreign matter deposited on the floating filter material is the key when the treatment is completed, backwashing is mainly used, but it is not efficient . In addition, in the case of floating filter media, water is absorbed by the passage of time and the specific gravity thereof is varied, thereby lowering the filtration efficiency.

In Korean Patent No. 239805, a method of cleaning a floating filter material by rotating a screw by a driving source has been proposed. However, in this method, filtration efficiency is lowered due to water absorption due to breakage of a floating filter material, A load may be generated on a screw or the like to cause a failure of the apparatus, and the filtration process and the washing process may not be continuous, thereby deteriorating the treatment efficiency.

Korea Patent No. 239805

Hereinafter, the structure and operation of the present invention will be described in more detail with reference to the accompanying drawings. In describing the present invention, terms and words used in the present specification and claims are to be construed in accordance with the principles of the present invention, on the basis that the inventor can properly define the concept of a term in order to best explain his invention It should be construed as meaning and concept consistent with the technical idea of.

The apparatus (1) of the present invention comprises a main body (2) having an inflow line (21) at one side and a discharge line (22) at the other side as shown in Fig. A separation plate (7) protruding from a lower surface of the main body (2) and having an upward slope at a position spaced apart from the inflow line (21); A heating means 8 for warming the raw water introduced through the inflow line 21 into the heating space 23 formed by the partition plate 7 and the side surface of the main body 2; An air diffusing pipe (6) formed between the main body (2) and the separating plate (7) to aerate the warming space (23); An adjusting unit 9 formed at a position spaced apart from the separating plate 7; A housing 3 in which a floating filter medium 31 of EVA material is embedded in the unit body 2 at one side of the control unit 9 and an upper screen 32 is formed on an upper surface thereof; A sinking part 4 formed at a lower end of the housing 3 and having a plurality of swash plates 41 formed to adjust an inclination gradient; (51) which is reciprocated by a driving means on rails formed on both sides of the upper end of the main body (3), and a washing water tank (51) formed in the feeding tank (51) (5) including a suction port (52) for sucking the suspended solids and an inlet (53) for sucking and discharging the suspended solids.

That is, according to the present invention, the sewage flows into the main body 2 from the inflow line 21 formed on the side surface of the main body 2, and the inflow sewage is subjected to the float separation process by aeration and warming in the processing space 23 And the sedimentation process is carried out while upwardly advancing the swash plate 41 of the sedimentation section 4 at the rear end of the sedimentation section 4. The upwardly flowing sewage is subjected to the filtration process while passing through the respective housings 3, , And the treated water that has undergone sedimentation and filtration is discharged to the outside through a discharge line (22) formed on the side surface of the main body (2).

The apparatus (1) of the present invention is a device for floatation, sedimentation and filtration of pollutants in the sewage, fresh water, early sewerage, sewer sewer sewage, etc., and is capable of continuous treatment .

That is, as shown in FIG. 1, the present invention is characterized in that the heating space 23 in which the floating separation is performed in one apparatus, the precipitation and filtration space 25 in which the precipitation and filtration is performed, the heating space 23 and the precipitation and filtration space 25 And floatation, sedimentation and filtration are performed in three spaces, respectively.

The air diffusing pipe (6) is configured to allow air to flow in the warming space (23) from the lower end thereof to perform floating separation.

2, the air diffuser 6 has an inner pipe 61 having a double pipe structure and an inner pipe 61a through which air is supplied and the inner pipe outlet hole 611 is formed along the longitudinal direction, And an outer tube 62 enclosing the outer tube 62 and forming an outer circumferential edge and a space 63 of the inner tube 61 and forming an outer tube 621 at an upper portion thereof.

As shown in FIG. 2, the inner pipe 61 is provided with an inner pipe 61 at its lower portion along the longitudinal direction, so that the air supplied through the inner pipe 61 is discharged from the space 63 And the discharged air is diffused in the space 63 to be discharged to the outer discharge hole 621. [

The air is diffused in the space 63 formed by the inner tube 61 and the outer tube 62 so as to discharge the air downward from the inner tube 61 and then the outer tube 621 The reason for spraying air through the outer discharge holes 621 is to uniformly blow air through each of the outer discharge holes 621 so that uniform floating separation can be performed throughout the heating space 23.

More preferably, the inner pipe discharging holes 611 are formed in a lower portion of the inner pipe 61 so as to reduce the distance between the inner pipe discharging holes 611 in the direction opposite to the direction in which the air is injected from the inner pipe 61 . As shown in the drawing, the distance d1 between the inner pipe discharging holes 611 in the direction in which the air is injected in the inner pipe 61 is larger than the distance d2 between the inner pipe discharging holes 611 located in the opposite direction in which air is injected .

This is because the inflation pressure of the air through the inner tube 61 will be smaller toward the end of the inner tube 61. Therefore, when the inner tube holes 611 are spaced apart from each other, The amount of the air discharged through each of the outer discharge holes 621 can be changed even if the discharge amount is reduced and diffusion is performed through the space 63. In this case, (61) is made smaller so that the number of the inner tube discharge holes (61) increases toward the end of the inner tube (61), so that the amount of air discharged from the entire inner tube (61) is uniform.

The separation plate 7 and the heating means 8 are configured to increase the floating separation efficiency in the heating space 23 so that the raw water flowing into the main body 2 through the inflow line 21 flows into the separation plate 7, So that a vortex is formed while the upward flow is formed, so that foreign matter having a relatively small specific gravity such as oil mixed with the raw water is separated and floated. The reason why the separator plate 7 is formed to have an inclined gradient is to increase the contact area with the raw water to induce the aggregation between the separated foreign substances to increase the efficiency of removing foreign matter. In addition, in addition to this, the raw water introduced by the heating means 8 is heated to lower the viscosity of the raw water, thereby separating foreign matter such as oil.

1 shows a basic example of the separator plate 7. The separator plate 7 has a plate shape and protrudes from the lower surface of the body 2 and is inclined upward in a position spaced apart from the inflow line 21. [ So that the heating space 23 is formed by the side surface of the main body 2 and the separating plate 7. It is preferable that the material of the separator 7 is made of a material that can conduct heat well by the heat generated by the heating means 8. [

The heating means 8 presents two embodiments in Fig.

1 shows an example in which the heat ray 8a is provided on the front surface of the separator plate 7, that is, on the surface in contact with the heating space 23, as a first heat ray 8a formed on the separator plate 7 However, the present invention is not limited thereto, and a structure in which it is buried in the separating plate 7 is also conceivable. As the heat ray 8a is formed in the partition plate 7, the inflowed raw water is separated from the oil by the collision with the partition plate 7 and contacts the partition plate 7 by the upward flow So that the raw water in contact with the separating plate 7 is directly heated to improve the separation efficiency of oil and other foreign matter.

3 shows an example in which the heat ray 8a is formed on the front surface of the separation plate 7. The heat ray 8a is formed on the front surface of the separation plate 7 in a plurality of stages in the transverse direction And each end is connected, and in particular, the mountain 82 and the valley 81 are alternately arranged at each end. FIG. 3 shows an example in which each end is formed in a wave shape, but it is not limited thereto, and it may be formed in a bent shape.

The reason why the heat line 8a is formed such that a plurality of stages are formed on the entire surface of the separation plate 7 and the mountains 82 and the valleys 81 are alternated at each stage, Is heated by the hot wire (8a) as well as vortices are formed by the hot wire (8a), thereby enhancing the separation efficiency of the foreign matter. Particularly, in the raw water in contact with the hot line 8a, oil fractions having a small specific gravity are gathered at the respective portions of the acid 82, so that mutual aggregation is caused to float the aggregated oil fractions. At this time, the viscosity of the raw water is lowered by the heat generated by the hot wire 8a naturally, and the efficiency of the oil fraction is increased.

1 shows a second embodiment of the heating means 8 in which a heat exchange medium is circulated in the heat exchange pipe 8b as a heat exchange pipe 8b formed at the lower end of the heating space 23, The raw water flowing into the space 23 is heated from the lower part to lower the viscosity.

The heating wire 8a and the heat exchange pipe 8b are connected to a heating means outside the main body 2 to supply a heat source though the heating wire 8a and the heat exchange pipe 8b are not shown in the figure, All are shown in FIG. 1, but this is optional.

4 and 5 show another example of the separator plate 7. The separator plate 7 shown in Fig. In this case, although not shown in the drawings, the heating means 8 may be constructed so that the heating wire 8a is contained in the separating plate 7 or the heat exchanging pipe 150b is installed in the heating space 23 have.

The separating plate 7a shown in Fig. 4 has a plate-like body 71 forming an inclined gradient and a plurality of guide plates 72 on the surface of the body 71 which is in contact with the heating space 23 And the guide plate 72 has a shape in which the mountains 72 and the valleys 71 are alternately formed.

The reason for this is that the raw water introduced into the warming space 23 has a large contact area at the separating plate 7a to induce separation and aggregation of oil by vortex formation or the like, The oil having a small specific gravity separated due to the shape is guided to the portion of the acid 722 to induce aggregation. More preferably, the discharge passage 73 is formed in the mountain 72 of the induction plate 72, and the coalesced oil is floated while being discharged to the upper portion, So that the oil seams up.

On the other hand, FIG. 5 shows another example. In the separator 7b shown in FIG. 5, a plurality of plate-like body portions 71 forming an inclined gradient are connected in parallel by a connecting rod 73, The portion 71 is different in height so that an inflow passage 74 is formed downward between adjacent body portions.

That is, a plurality of body portions 71 having different heights are arranged at the outermost side of the body portion 71 having the largest height, and the body portions 71 having different heights are arranged in parallel So that an inflow passage 74 is formed at a lower portion between the body portions 71 which are formed in the body.

5, the raw water flowing into the warming space 23 flows through the inflow passage 74 to flow on the lower portion of the body portion 71, (71 ') which is located at the upper part of the body (71) so as to maximize the contact area with the raw water so as to induce separation and agglomeration of foreign matter such as oil.

Particularly, the foreign matter separated from the raw water flowing through the body portion 71 located at the lower portion is floated by the specific gravity, and the floating foreign matter is flowed on the body portion 71 ' .

The control part 9 is formed at a position spaced apart from the separating plate 7 and is formed with rotary plates 92 and 94 for rotationally interlocking with each other by a rotary shaft 91. Separated from the upper ends of the rotary plates 92 and 94 A pressing sensor 95 is formed inside the immersion plate 93 to adjust the magnitude of the pressure of the immersion plate 93 immersed in the immersion plate 93 The rotary plates 92 and 94 are rotated to contact the upper end of the separation plate 7 to form a vortex or to be separated from the separation plate 7 to form a flow passage.

The rotation shaft 91 is formed in the main body 2 in parallel with the separation plate 7 while forming a gap from the separation plate 7 and is connected to the main body 2 by a driving means such as a motor So that rotation can be interlocked.

The upper and lower plates 92 and 94 of the rotary plates 92 and 94 are rotatably connected to each other by a rotary shaft 91. As shown in FIG. 6A, The flow path 24 is formed so that the rotary plates 92 and 94 are spaced apart from the separating plate 7 when the foreign matter such as oil is sufficiently separated so that the raw water w, And moves along the downward flow through the flow path 24 formed by the rotary plates 92 and 94 by the plate 7.

On the other hand, as shown in FIG. 7 (b), when the oil and other foreign substances are not sufficiently separated by the above-mentioned operating mechanism in the warming space 23, the rotary plates 92, Make contact with the top. As a result, vortices are formed by the upper plate 92 and the residence time in the warm space 23 becomes longer as shown in the drawing, in the warm water space 23 upward in the warming space 23 on the separator plate 7 will be. By such an operating mechanism, the residence time of the raw water in the warming space 23 is made long, so that foreign matter such as oil is sufficiently separated from the raw water.

The immersion plate 93 protrudes from the upper end of the rotary plates 92 and 94, that is, the upper end of the upper plate 92. Oil fractions and the like, which are separated from the raw water, . In particular, a pressure sensor 95 is provided in the immersion plate 93 to sense the magnitude of the pressure due to the oil impregnated in the immersion plate 93. When the sensed pressure exceeds a predetermined pressure, that is, When the oil or the like is separated from the raw water and the oil or the like is sufficiently deposited on the deposit plate 93 as shown in FIG. 6A, resulting in a sensing value exceeding a predetermined pressure, the separation plate 7, And a flow path 24 is formed between the rotary plates 92 and 94. Also, as shown in FIG. 6B, when the sensed pressure is lower than a predetermined pressure, that is, when the oil is not sufficiently separated from the waste water, the oil is not sufficiently deposited on the deposit plate 93, The rotary plates 92 and 94 are rotated so that the upper end of the separation plate 7 and the rotary plates 92 and 94 come into contact with each other as described above, To the space (23).

A weight 96 is provided under the lower plate 94 so that the rotation of the rotary plates 92 and 94 in the state of FIG. 6B to FIG. 6A is controlled by a weight 96, .

As described above, the control unit 9 corresponds to a configuration in which the direction of the water flow is adjusted so that foreign matter such as oil is sufficiently separated from the raw water in the warming space 23.

The raw water is introduced into the immersion and filtration space 25 in a state where foreign substances such as oil having a relatively small specific gravity are separated through the heating space 23 and the flow path 24.

The housing 3 is formed so that the floating filter material 31 on the water surface formed on the main body 2 is not biased to one side so that sewage or the like is uniformly filtered as a whole.

The housing 3 is provided with a housing 3 in which the floating filter 31 is installed in the form of a unit unit so that the sewage is smoothly flowed in accordance with the upward flow and the filtered processed water is smoothly discharged, 3 and an upper screen 32 formed on the upper surface of the housing 3. The lower surface of the housing 3 is configured to communicate with the settling portion 4. [

The upper screen 32 is formed of a mesh net or the like having a mesh smaller than the particle size of the floating filter material 31 though not shown in the drawing to prevent the floating filter material 31 from being discharged to the outside of the housing 3 So that the float is exposed to the outside. At this time, the housing 3 can be mounted in the main body 2 by various known techniques, and a description thereof will be omitted.

The settling portion 4 is formed at the lower end of the housing 3 in communication with the housing 3 and a plurality of swash plates 41 are formed to adjust the slope gradient.

The reason why the settling portion 4 is formed by the plurality of swash plates 41 is that the high-boiler foreign matter contained in the sewage is precipitated and removed to the bottom of the main body 2 by the upward flow method, The low specific gravity foreign matter contained in the sewage is upwardly precipitated and removed again while forming a flock. After the low specific gravity particles are removed, the sedimentation of the sewage is performed so as to remove floating foreign matter by the floating filter material 31 in the housing 3 This is to increase the sedimentation area while shortening the distance.

That is, the shape of the precipitating part 4 is formed to be inclined upward from the bottom, and the low specific gravity foreign matter contained in the sewage introduced from the bottom is raised in an oblique direction so as to maximize the settling area, It is to be settled.

As shown in FIG. 1, the lower screen 42 is formed at the lower end of the outermost swash plate 41 in the settling unit 4, and is not hung on the outward swash plate 41, but is hinged to the swash plate 41, It is reasonable to configure it so that it can be interlocked. In this way, the lower screen 42 is configured to smoothly guide the sewage to the settling unit 4, and at the same time, the lower screen 42 itself has a larger settling area with the sewage.

Particularly, the plurality of swash plates 41 constituting the settling portion 4 are formed so as to adjust the slope gradient. The reason why the slope gradient is controlled is that the backward flow or the like is generated depending on the water quality and the flow rate of the sewage flowing into the main body 2 In order to improve the applicability. For example, when the flow rate is large, the swash plate 41 of the settling portion 4 is vertically oriented to shorten the residence time of the inflow sewage in the settling portion 4 and the housing 3, .

To this end, the present invention provides an embodiment of the sinking part 4 as shown in FIG. In the present embodiment, the upper end of each swash plate 41 is hinged to the support 43.

An angle regulating base 44 is formed at the lower portion of the support base 43 and includes a plurality of engaging protrusions 441 formed on one side of each of the inclined plates 41. By the lateral operation of the angle regulating base 44 The inclination of each swash plate 41 is uniformly adjusted. The lateral operation of the angle adjuster 44 can be automatically operated by a combination of known techniques as well as a manual operation.

In other words, the water quality and the flow rate are automatically sensed and the angle adjusting table 44 is moved in the lateral direction according to the sensing value, and each of the latching projections 44 pushes one surface of each swash plate 41 by this flow, And the angle adjustment in the opposite direction causes the angular adjustment plate 44 to flow in the opposite direction so that each of the locking projections 44 supports the one surface of each swash plate 41, It is possible to adjust the angle uniformly.

Although not shown in the drawing, the angle adjuster 44 can uniformly adjust the swash plate 41 of the entire settling portion 4 and can adjust the angle of the settling portion 4, which is dependent on each housing 3, It is a matter of course that the angle adjusting rods 44 may be provided to allow individual angle adjustment.

8, the angle adjuster 44 includes a plurality of outer closure protrusions 442-1 and an outer closure protrusion 442-1 which are engaged with one surface of the alternate swash plate 41 among the swash plates 41, An inner pipe 443 formed with an inner pipe locking protrusion 443-1 which slides inside the outer pipe 442 and protrudes into the long hole 442-2, Are included.

The reason for such a construction is that in addition to the uniform angle adjustment shown in FIG. 7, the alternating swash plate 41 strikes the opposing swash plate 41, as shown in FIG. 8, so as to desorb the foreign substances deposited on the swash plate 41 .

This is because it is difficult for the cleaning by the cleaning and suction means 5 to be described below to reach the swash plate 41 at the bottom or the bottom of the floating filter medium 31, So that the deposited foreign matter is desorbed.

The operation of the angle adjuster 44 of this embodiment will be described. First, the uniform inclination adjustment of each swash plate 41 is made possible by the lateral operation of the outer tube 442. In other words, each of the outer clogging protrusions 442-1 and the inner closure protrusions 443-1 pushes or supports one surface of each of the swash plates 41. [

Next, in the case of removing the swash plate 41, the outer tube 442 is fixed and the inner tube 443 is slid on the outer tube 442, so that the inner tube locking protrusion 443-1 is moved from the long hole 442-2 Only the alternate swash plate 41 supported by the inner pipe locking protrusion 443-1 while being slid is interlocked with the hinge so as to strike the opposing swash plate 41 so that the foreign matter deposited on the swash plate 41 is removed .

In the present invention, when the floating separation, the upward flow type precipitation and the filtration process are performed as described above, the filtration efficiency is lowered due to the treatment of floating matters on the water surface as well as the floating filter material 31 contained in the housing 3 is blocked The present invention allows the cleaning process to proceed in succession to the precipitation and filtration process by configuring the cleaning and suction means 5.

The washing and sucking means 5 is connected to a driving source such as a normal motor or the like on a rail 54 provided on both sides of the main body 2 by a chain or a belt so as to be rotated by a driving means for rotating the shaft, (51), and spraying water or air to the floating filter medium (31) while spraying the floating filter medium (51) to clean the floating filter medium (31) And a suction port 53 for sucking and discharging floating foreign matter among the foreign substances generated by the cleaning of the cleaning mouth 52. [

That is, the cleaning and sucking means 5 is configured such that water or air is sprayed to the floating filter medium 31 at a high pressure by the washing port 52 provided in the conveying truck 51 which has completed the filtration process or reciprocates in the filtration process The particles having a large specific gravity among the foreign substances generated at this time are precipitated in the form of a flake and the particles having a small specific gravity among the foreign substances are treated by the inlet 53.

Further, in the present invention, the filter unit 10 shown in FIG. 9 and the like may be configured in the discharge line 22 to further improve the quality of the discharged water.

9, a spiral guide 132 is formed on the inner surface of the tube where the upper end is blocked, and a raw milk inlet 13 (see FIG. 9) in which a perforation 134 is formed through the spiral guide 132, ); A plurality of hollow fiber membrane unit bodies 11 formed of hollow fiber membranes having a predetermined length are fixed by a pair of upper and lower binding members 122a and 122b, (12); A housing 14 having a cylindrical shape with the upper and lower ends penetrating therethrough while the hollow fiber membrane assembly 12 is housed, and a concentrated water outlet 142 for discharging pollutants by washing on the outer peripheral surface; A process water outlet 152a for discharging process water is formed on the upper side of the housing and a raw water inlet 152b for supplying raw water to the raw milk inlet pipe 13 is formed on the upper side, And a lower header (15a, b).

First, the hollow fiber membrane unit 11 has a plurality of hollow fiber membranes having a predetermined length, which are not shown in the figure but are filled with an adhesive resin in an upper / lower cap having one opening, And the hollow fiber membrane unit 11 is formed by curing.

The hollow fiber membrane unit 11 preferably has an outer diameter of 0.5 to 8 mm and is composed of several to several dozen hollow fiber membranes. That is, when the outer diameter of the hollow fiber membrane is 0.5 mm or less, the density of the hollow fiber membrane is increased. As a result, the vortex phenomenon of the raw water discharged through the raw water inlet (13) On the other hand, when the outer diameter of the hollow fiber membrane is 8 mm or more, the density of the hollow fiber membrane is lowered, thereby reducing the amount of water treatment to the raw water. On the other hand, it is preferable that the number of the hollow fiber membranes constituting the hollow fiber membrane unit 11 is about 5 to 30.

That is, when the number of the hollow fiber membranes constituting the hollow fiber membrane unit 11 is five or less, the density of the hollow fiber membrane assemblies 12 is increased when the hollow fiber membrane assemblies 12 are reconfigured. As a result, The water treatment efficiency is lowered. On the other hand, when the number is 30 or more, the density of the hollow fiber membrane assembly 12 is reduced when the hollow fiber membrane assembly 12 is reconfigured, thereby reducing the amount of water treatment.

In addition, the upper and lower ends of the hollow fiber membrane unit 11 are blocked by a cylindrical upper / lower cap filled with an adhesive resin. The diameter of the upper / lower caps is preferably about 1.2 to 20 mm.

That is, when the diameter of the upper / lower cap is 1.2 mm or less, the density of the hollow fiber membrane assembly 12 is increased at the time of reconstitution of the hollow fiber membrane assembly 12, so that the space for flowing the raw water is not secured. If the diameter is 20 mm or more, the density of the hollow fiber membrane assembly 12 at the time of reconstitution is lowered, thereby reducing the amount of water treatment.

9, a plurality of hollow fiber membrane units 11 are arranged on the upper and lower binding members 122a and 122b, and the upper and lower binding members 122a and 122b ), And then wrapping the raw milk feed tube 13.

The hollow fiber membrane assembly 12 has a cylindrical shape that surrounds the raw milk feed tube 13. That is, the hollow fiber membrane module assembly 12 is rolled from one end of the hollow fiber membrane assembly 12 to connect the hollow fiber membrane module assembly 12 to the center of the hollow fiber membrane module assembly 12, and adjacent hollow fiber membrane unit bodies 11 are brought into contact with each other.

In the raw milk feed pipe 13, a helical guide 132 is formed on the inner surface of the pipe where the upper end is blocked, and the perforation 134 passes through the helical guide 132 at a predetermined height. Therefore, the raw water supplied to the raw milk inflow pipe 13 is vapored through the upper bore 134 while the speed is increased by the helical guide 132, and vapors are generated around the raw water.

At this time, the vortex phenomenon acts to knock the hollow fiber membrane unit 11 constituting the hollow fiber membrane assembly 12 and simultaneously perform the water treatment through the hollow fiber membrane unit 11. Therefore, it is preferable that the diameter of the raw milk inflow pipe 13 is 15-30 mm.

At this time, when the diameter of the raw milk inflow inlet 13 is 15 mm or less, the pressure of the raw water is increased and the supply of the raw water can not be smoothly performed. In addition, in the process of screwing and fixing the hollow fiber membrane assembly 12, . On the contrary, when the diameter of the raw milk inflow pipe 13 is 30 mm or more, the pressure of the raw water to be inflow is small, so that the vortex phenomenon of the raw water is not only weakened but also the tightness to the top and bottom of the hollow fiber membrane assembly 12, . On the other hand, the perforation 134 of the raw milk inflow inlet 13 is preferably formed between the upper 1/3 and 2/3 of the height. At this time, if the height of the perforation 134 is formed from the upper 1/3 or more point, the dispersion of the inflow water is not smooth, so that the surface contaminants of the hollow fiber membrane unit and the hollow fiber membrane unit 11 of the hollow fiber membrane assembly 12 are effectively It can not be removed.

On the contrary, if the pressure is formed from 2/3 or less of the upper side, the inflow pressure of the raw water is small and the vortex phenomenon is reduced. In other words, the perforations 134 are formed in the upper 1/3 to 2/3 of the raw milk-inflow inlet 13, thereby achieving a smooth vortex phenomenon at a high inflow pressure of the raw water. Accordingly, the spiral guide 132 accelerates the flow rate of the raw water flowing into the hollow fiber membrane assembly 12, and vortexes are generated by sprinkling the raw water discharged through the pores 134, The unit body 11 is vibrated. By this action, the contaminants attached to the surface of the hollow fiber membrane unit 11 are removed, and the water treatment is smoothly performed through the hollow fiber membrane unit 11 from which the contaminants are removed.

The present invention also includes a housing 14 for covering a hollow fiber membrane module (raw milk feed pipe 13 and hollow fiber membrane assembly 12) and an upper / lower header 15a , 15b.

The housing 14 is formed into a cylindrical shape having upper and lower ends penetrated to cover and cover the hollow fiber membrane module, and at one side thereof, a concentrated water outlet 142 is formed to discharge contaminants generated from raw water .

That is, the housing 14 covers the outer surface of the hollow fiber membrane module, and at the lower end of the hollow fiber membrane module, a concentrated water outlet 142 for discharging contaminants and concentrated inflow water separated from the hollow fiber membrane assembly 12 during washing . At this time, a valve is formed in the concentrated water discharge port 142 and is constantly opened to the extent that the pressure loss of the inflow water is minimized, thereby continuously discharging contaminants and concentrated inflow water filtered by the hollow fiber membrane assembly 12, Thereby preventing accumulation.

In other words, by opening the concentrated water outlet 142 so that the pressure loss of the raw water flowing through the raw milk inflow inlet 13 is minimized, the contaminated water introduced into the raw milk inflow inlet 13 flows through each hollow fiber membrane unit 11 At the same time as the water treatment is performed, contaminants or the like filtered out are continuously discharged through the concentrated water outlet 142.

The upper and lower inner peripheral surfaces of the housing 14 and the upper and lower outer peripheral surfaces of the housing 14 and the upper and lower outer peripheral surfaces of the housing 14 and the upper and lower ends of the upper and lower ends of the housing 14, O rings for adhering end portions of the hollow fiber membranes 15a and 15b are respectively coupled to prevent loss of treated water through the hollow fiber membrane assembly 12. In addition, On the upper / lower outer peripheral surfaces, threads for coupling the upper / lower headers 15a and 15b are formed.

The upper and lower headers 15a and 15b are respectively connected to the upper and lower outer circumferential surfaces of the housing 14 as a funnel shape. At the center of the upper header 15a, the treated water purified by the hollow fiber membrane module is moved upward And a raw water inlet 152b for supplying raw water to the raw milk inlet 13 of the hollow fiber membrane module is formed at the center of the lower header 15b.

At this time, a valve is formed in each of the treated water outlet 152a and the raw water inlet 152b to selectively adjust or shut off or open the valve.

Accordingly, when the raw water is supplied through the raw water inlet 152b and the water is treated using the raw water, the treated water outlet 152a is opened to perform a smooth water treatment, and the raw water is supplied through the raw water inlet 152b, The process water outlet 152a is blocked and the concentrated water outlet 142 is opened to smoothly discharge pollutants.

First, the action of the water treatment using raw water will be more specifically described. The concentrated water outlet 142 is tightened or cut off, and the treated water outlet 152a is opened. Then, the raw water is supplied through the raw water inlet 152b of the lower header 15b and flows into the raw milk feed inlet 13 of the hollow fiber membrane module.

At this time, since the inflowing raw water rotates along the helical guide 132, the velocity is increased and discharged at a high rate through the perforation 134. The raw water thus discharged is purified through the hollow fiber membrane unit 11 constituting the hollow fiber membrane assembly 12 and discharged to the open upper side and then discharged smoothly through the treated water outlet 152a of the upper header 15a .

On the other hand, if the cleaning process using raw water is more specifically described, the concentrated water outlet 142 is opened and the treated water outlet 152a is shut off. Then, the raw water is supplied through the raw water inlet 152b of the lower header 15b and flows into the raw milk feed inlet 13 of the hollow fiber membrane module.

At this time, since the inflowing raw water rotates along the helical guide 132, the velocity is increased and discharged at a high rate through the perforation 134. The raw water thus discharged basically generates vibrations while hitting the hollow fiber membrane unit 11 constituting the hollow fiber membrane assembly 12 so that contaminants attached to the surface of the hollow fiber membrane unit assembly 11 are discharged, .

That is, the raw water discharged through the perforations 134 is prevented from adhering foreign matter to the surface by striking the hollow fiber membrane unit 11 constituting the hollow fiber membrane assembly 12 during water treatment, Is discharged to the concentrated water outlet (142) during cleaning, so that clean cleaning is performed. In addition, the efficiency of the water treatment can be improved by preventing the adhesion of contaminants to the surface of the hollow fiber membrane unit 11 (hollow fiber membrane) constituting the hollow fiber membrane assembly 12.

11 and 12 show one embodiment of the filter unit 10. In the present embodiment, one end is fixed to the lower header 15b and the other end is exposed through the hollow fiber membrane assembly 12, (145). As described above, when the vortex is generated in the water treatment process and the washing process, vibration is applied to the vibration bar 145, So that the hollow fiber membrane unit 11 constituting the hollow fiber membrane assembly 12 is also subjected to vibration so that the foreign substance deposited on the surface is washed.

In addition, the raw milk infusion inlet 13 of the present embodiment includes a lower tube 135 having a spiral guide 135-1 formed therein and a perforation 135-2 formed through the spiral guide 135-1 at an upper portion thereof; An upper pipe 136 communicating with the lower pipe 135 by an on-off valve (b) and having a plurality of discharge holes 136-1 formed at a rim of an upper surface thereof; A rotation shaft 137 projecting from a central portion of the upper tube 136; A rim connected to the rotation shaft 137 at a position that is rotatable at the upper end of the rotation shaft 137 and which connects the plurality of rotation blades 138-1 to the ends of the plurality of rotation blades 138-1 at a position facing the discharge hole 136-1, A rotation drive part 138 formed of a ring 138-2; And a plurality of striking ends 139 protruding from the rotation driving unit 138 and striking the vibrating bar 45 in accordance with rotation of the rotation driving unit 138.

The lower tube 135 has the same function as the raw milk infusion inlet 13 described with reference to FIG. 11 and the like, and thus a description thereof will be omitted.

The upper pipe 136 is communicated with the lower pipe 135 by an on-off valve (b), and a plurality of discharge holes 136-1 are formed on the upper edge of the closed structure. The raw water flowing into the lower pipe 135 flows into the upper pipe 136 and is discharged upward through the discharge hole 136-1 when the opening / closing valve b is opened (washing process) . When the open / close valve (b) is closed (water treatment process), raw water is discharged only through the lower pipe (135).

The rotation driving unit 138 is rotatably coupled to an upper end of a rotation shaft 137 protruding from a center of the upper tube 136. The rotation driving unit 138 includes a plurality of rotary blades 138-1 and a frame ring 138-2 connecting the ends of the plurality of rotary blades 138-1. The raw water discharged through the discharge hole 136-1 is supplied to the plurality of rotary blades 138 -1) so that a rotational force is applied to the rotation driving unit 138.

The striking end 139 protrudes from the rotation driving part 138 and strikes the vibrating bar 145 in accordance with the rotation of the rotation driving part 138. The raw water introduced in the cleaning step is supplied to the lower pipe 135, The raw water discharged and discharged through the perforation 452 along the helical guide 132 is blown against the hollow fiber membrane unit body 11 to be cleaned. In addition, the raw water discharged through the upper tube 136 The vibrating bar 145 may be struck by a striking end 139 integrally rotating with the rotation driving unit 138 to apply a foreign substance or the like deposited in the filtration process of the hollow fiber membrane unit 11 to the vibrating bar 145 So that the washing process can be performed. It is appropriate that the striking end 139 is made of a soft material.

In this embodiment, the opening / closing valve b is opened in the cleaning process so that the lower tube 135 and the upper tube 136 are communicated with each other to form a vortex through the lower tube 135, and the upper tube 136 So that the swinging end 139 strikes the vibrating bar 145 and vibrates the vibrating bar 145 so that the vibrating bar 145 vibrates. . The vibration applied to the vibrating bar 145 is transmitted to the hollow fiber membrane assembly 12 so that the foreign substances deposited on the hollow fiber membrane unit 11 of the hollow fiber membrane assembly 12 can be easily removed, .

13, except that the pressure sensor module 16 and the control unit (not shown) are provided in the same manner as in the basic example shown in FIG. 17) is further configured.

The pressure sensor module 16 is composed of a plurality of pressure sensors 161, 162, 163 and 164 on the side of the housing 14, and in FIG. 13, four pressure sensors are arranged in four directions. It is.

The pressure sensor module 16 may detect whether the hollow fiber membrane unit 11 is blocked or damaged by a pressure difference between the pressure sensors during the water treatment process. For example, when the pressure value sensed by the pressure sensor 161 is significantly smaller than or greater than that of the pressure sensors 162, 163, 164, the hollow fiber membrane unit unit 12 of the hollow fiber membrane assembly 12, (11) is blocked or damaged.

In the case where it is determined that the pressure value is remarkably different, the predetermined set value is used as a reference, and the threshold value (critical range) for the occlusion or breakage of the hollow fiber membrane assembly 12 is derived from the experimental results, Range), the controller 17 automatically senses this, thereby stopping the operation of the apparatus in the event of a breakage or allowing the cleaning process to be carried out in the case of occlusion.

As an example of the action between the controller 17 and the pressure sensor module 16, when the sensed value of the pressure sensor having the highest pressure value in the pressure sensor module 16 exceeds the breakage reference value, The control unit 17 stops the water treatment process by stopping the flow of raw water to the concentrated water outlet (13), and stops the water treatment process when the sensing value of the pressure sensor having the lowest pressure value in the pressure sensor module (16) 142 to open the cleaning process.

In this case, when the hollow fiber membrane unit 11 is broken, the incoming raw water is discharged as a broken part, thereby pressing the side surface of the housing 14 to increase the pressure value. Therefore, when the hollow fiber membrane unit 11 is broken, When the hollow fiber membrane unit 11 is closed, the raw water flowing into the hollow fiber membrane unit 11 does not flow into the obstruction portion, and the pressure value at the side of the housing 14 will decrease. Therefore, In the case of blockage of the unit body 11, the pressure value to be sensed is set as the occlusion reference value.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the invention.
