Description

Welding panel without wall and water tank using the same {Guiding wall without welding and water tank using the same}

The present invention relates to a non-welded panel ditch wall and a water tank using the same, and more particularly, a flow path through which water flows at the same time as the construction is simple by fabricating a ditch wall installed inside the water tank to extend the residence time of water. The present invention relates to a non-welded panel ditch wall capable of preventing the generation of stagnant water in a phase and a water tank using the same.

Generally, the storage water tank used in the advanced water treatment system is made of a large-scale rectangular concrete material buried underground.

The advanced water treatment system is a rubber beam with air supply, and overflows the river water, and settles the soil, sand, and various foreign substances in the raw water drawn up by the intake pump, and after stirring the flocculant, powdered activated carbon, chlorine, etc. Mixed paper and flocculation paper to form impurity lumps with the device, sedimentation basin for depositing various impurities and overflowing clean clear water only, sand filter paper for filtering out fine impurities through sand layer, and water supplied through medium pressure pump. It is used for ozone contact paper for water treatment, biological activated carbon adsorption paper, and purified water pipes connected to water pumps.

Conventional rectangular concrete water tank used for the purified water is supplied with chlorine (water) to the water for the purpose of sterilizing various bacteria that may be contained in the filtered water from the sorbent, chlorine spread throughout the water and mixed After storage for a period of time (approximately 30 minutes), it is configured to feed home via a water pump.

The conventional water tank is a hexahedron having an empty internal space buried underground, and has a form in which a water pipe having a chlorine injector penetrates the upper portion of the water pipe and a drain pipe penetrates the water supply pump and the lower portion thereof. .

The conventional water tank described above includes the following problems.

In conventional water tanks, the time for chlorine to spread throughout the water is designed to be within 30 minutes, so that chlorine is discharged to the outlet immediately before being sufficiently diluted in water, or tap water without sufficient sterilization time can be supplied to the home.

For example, when tap water with excessive residual chlorine concentration is supplied to the home, it is not suitable as drinking water because of high chlorine concentration in tap water, and it is not suitable for drinking water, and it is also possible to generate carcinogen trihalomethane (THM). This may be high or an accident may occur that provides the user with water containing various invisible bacteria and the like.

These accidents can be prevented if chlorine and water are sufficiently exchanged to ensure that the residual chlorine concentration is maintained at an appropriate level. To do this, it is best to allow chlorine and water to contact for a sufficient time while maintaining a smooth flow of water.

Of course, in the conventional water tanks, zigzag-type ditch walls are formed to protrude on the inner wall surface so that the flow of the fluid can be long by interfering with the advancing direction of the fluid, so that chlorine and water can be contacted while flowing in the 'S' shape. There is a case. In this case, the contact time of water and chlorine in the water tank can be relatively long.

And the other side of the main body 10 is formed with an outlet for outflow of water, the outlet pipe 19 is connected to the outlet. Water introduced into the main body 10 is discharged after staying inside the main body 10 for a set residence time. The water flowing into the main body 10 is induced by the flow walls installed inside the main body 10 to form a meandering flow path, thereby extending the residence time of the water. The residence time is set so that water and chlorine, ozone, disinfectant, liquid and solid disinfectant can be sufficiently mixed.

The conductive wall according to the embodiment of the present invention is formed of a plurality of partitions. On the contrary, it can be formed of one compartment.

For convenience of explanation, a plurality of partitions are described by dividing the first compartment 20 and the second compartment 50. The first compartment 20 and the second compartment 50 are alternately arranged in a zigzag manner inside the main body 10.

The first compartment 20 extends so that one end thereof is connected to the first side wall 11 and extends toward the opposite second side wall 15, but does not extend to the second side wall 15. That is, the other end of the first compartment 20 is formed to be spaced apart from the second side wall 15 by a predetermined distance. In addition, one end of the second compartment 50 is connected to the second side wall 15 and extends in the direction of the first side wall 11, but does not extend to the first side wall 11. That is, the other end of the second compartment 50 is formed to be spaced apart from the first side wall 11 by a predetermined distance.

In the illustrated example, the two first compartments 20 are spaced apart from each other and installed side by side inside the main body 10, and the two second compartments 50 are alternately arranged with the first compartments 20. do.

The water introduced into the main body 10 by the flow walls having the first and second compartments 20 and 50 described above is not directly discharged to the outside through the outflow pipe 19, but rather the first and the second. The residence time is greatly extended because it flows zigzag along the two compartments 20 and 50 to form a meandering flow path.

The first compartment 20 is formed between the struts 21 supporting the top plate at regular intervals on the floor, and a plurality of unit panels 23 are coupled to each other, and the barriers are arranged at regular intervals. And a fastener surrounding the reinforcement bar 30 and the reinforcing bar installed to increase the strength of the diaphragm, and a fixing member fixing the fastener to the unit panel. The first compartment 20 may be formed at a height connected to the top plate, or may be formed at a height that does not reach the top plate.

The struts 21 are formed at regular intervals inside the body. Each strut 21 may use concrete or rectangular steel. Each diaphragm provided between the struts 21 is formed by combining five unit panels 23 with each other.

Each of the unit panels has a plate-shaped base plate 25, a first bent portion 24 formed at one side of the base plate 25, and one side of the first bent portion 24. The connection part 27 formed is provided. The first bent portion 24 is bent in a shape corresponding to the reinforcement bar 30 so as to surround a part of the reinforcement bar 30.

The reinforcement bar 30 is installed side by side at a predetermined interval in the diaphragm to increase the strength of the diaphragm. In the illustrated example, the reinforcement bar 30 is made of a square pipe, but can be made of various shapes. The lower end of the reinforcement bar 30 is fixed to the body bottom 8. The reinforcement bar 30 is mounted to be connected to a part of the first bent portion 24 formed in the unit panel 23.

The reinforcing bar 30 is fixed to the unit panel 23 by the fastener 35 and the fixing member. The fastener 35 is formed by bending the first bent portion 24 in a shape corresponding to the reinforcement bar 30 so as to surround a part of the reinforcement bar 30 in a region outside the region surrounding the reinforcement bar 30. On the other side of the second bending portion 37, the first extension portion 38 formed on one side of the second bending portion 37 and coupled to the connecting portion 27 by the fixing member, and the second bending portion 37 It is formed and has a second extension portion 39 which is coupled to the base plate 25 by a fixing member.

A bolt 41 and a nut 43 are used as the fixing member. Therefore, a plurality of bolt insertion holes 36 are formed at predetermined intervals in the first and second extension parts 38 and 39 of the fastener. And bolt insertion holes are also formed in the base plate and the connection portion of the corresponding position.

In order to couple the two unit panels 23, the first bent portion 24 of the unit panel 23 is positioned to surround the back of the reinforcing bar 30, and then another unit panel is disposed next to the unit panel 23. In this case, the base plate of another unit panel overlaps with the rear side of the connection part 27 of the unit panel installed first. In this state, the second bent portion 37 of the coupler 35 is positioned to surround the front surface of the reinforcing bar 30. The second bent portion 37 surrounds the entire reinforcement bar 30 together with the first bent portion 24. The first extension part and the second extension part 38 and 39 of the coupler are in close contact with the front surface of the connecting portion 27 and the front surface of the base plate 25, respectively. In this state, the bolt insertion hole 36 is drilled and then fastened using the bolt 41 and the nut 43.

In the illustrated example, the fasteners are formed to be the same as the upper and lower lengths of the unit panel. Alternatively, as shown in FIG. 40, a plurality of fasteners 35 having a short length may be installed at regular intervals.

Meanwhile, among the unit panels, the unit panel adjacent to the strut 21 is further formed with a lip 29 at the edge of the base plate 25 or more ribs at the edge of the connecting portion 27 as shown in FIG. 4. Can be formed. In the example of FIG. 4, the lip 29 is formed bent at a right angle at the edge of the base plate 25. Lip 29 is fixed to post 21 by bolts. When the unit panel having such a structure is installed to be supported by the first or second side walls 11 and 15, the lip 29 is fixed to the first or second side walls 11 and 15.

The unit panels 23 described above may have a coating film formed on the surface of the metal substrate. The coating film may be formed by applying a coating material containing polyurethane or polyurea. In addition, the hybrid resin which mixed polyurethane and polyurea can be used. The coating material may further contain an acrylate, silane or silicone which can improve the adhesion. The coating material has advantages of high elasticity, water resistance, impact resistance, and the like, compared to conventional coating resins such as epoxy or alkyd resin. In particular, the coating material is harmless to the human body because it does not use a solvent.

Meanwhile, as shown in FIGS. 6 and 7, the first compartment may be formed by unit panels being combined in left and right directions and up and down directions. In this case, the unit panel is preferably provided with a horizontal plate portion 33 is bent at a right angle to the top and bottom of the base plate 25 to be mutually coupled up and down. The horizontal plate portion 33 overlaps with the horizontal plate portion of the unit panel adjacent in the vertical direction. A bolt insertion hole is formed in the horizontal plate portion 33 and is fastened by a bolt and a nut.

On the other hand, since the structure of the second compartment 50 is the same as the first compartment 20, a detailed description thereof will be omitted.

Another embodiment of the unit panel is shown in FIG. 5. In the illustrated example, the unit panel 40 has first bent portions 43 formed on both left and right sides of the base plate 41, respectively. And the connection part 45 is formed in the edge part of each 1st bending part 43. As shown in FIG. The unit panel 40 having the above configuration is arranged alternately before and after the reinforcing bar 30 to be coupled to each other. Each connecting portion 45 is fixed to two unit panels by using a bolt and nut after drilling the bolt insertion hole.

Another embodiment of the unit panel is shown in FIG. 41. The unit panel 8 includes a base plate 81 and first bent portions 83 formed on both left and right sides of the base plate 81. In the illustrated example, the first bent portion 83 is bent at an angle of about 45 degrees with respect to the base plate 81 to extend a predetermined length. The first bent portion 83 is connected to one surface of the reinforcing bar 30. In FIG. 41, the first bent portions 83 of the unit panels are coupled at both sides of the reinforcing bar 30 to couple the adjacent unit panels. In this state, the fastener 35 is disposed on the rear side of the unit panel 8. The reinforcement bar 30 and the fastener 35 are the same as the embodiment of FIG. 1. Then, the reinforcing bar 30, the unit panel 8, and the fastener 35 are coupled to each other by using the u bolt 90 and the nut 95. A hole 85 penetrating through the unit panel 8 and the fastener 35 is formed to mount the u-bolt 90. The u-bolt 90 is inserted into the hole 85 from the front of the unit panel 8 to fasten the nut 95.

In FIG. 1, the inside of the main body 10 has a point where the first, second, third and fourth side walls meet each other, a point where the first side wall 11 and the first partition 20 meet, and a second side wall ( Corners are formed at the points where 15) and the second compartment 50 meet. In these corners, the flow of water is weak, causing water to stagnate. When stagnant water is generated in the flow path, the water flow is not smooth, so that dilution performance of chlorine, ozone, fungicides, liquid and solid disinfecting chemicals is degraded, and water quality is deteriorated. To this end, the present invention preferably includes a stagnant water prevention part to prevent stagnant water from occurring in the flow path formed by the first and second compartments 20 and 50.

As shown in FIG. 9, the stagnant water prevention part is provided with guide vanes 60 respectively installed in the first compartment 20 and the second compartment. The guide feather 60 installed in the first compartment is formed in the support 21 coupled to the end of the first compartment 20. The height is the same as the height of the first compartment 20. The guide feather 60 extends a predetermined length in a corner direction formed by the second compartment 50 and the second side wall 15 adjacent to each other on the front side. In addition, the guide feather 60 formed in the first compartment 20 positioned at the foremost of the plurality of first compartments 20 may extend in the corner direction where the side walls of the body 10 meet.

The guide feather 60 provided in the second compartment is also formed in the support coupled to the end of the second compartment 50, and the height is the same as the height of the second compartment. The guide feather 60 extends a predetermined length in a corner direction formed by the first compartment 20 and the first side wall 11 adjacent to each other on the front side. By the guide vane 60 described above, water flows in a corner direction, thereby effectively preventing stagnant water from occurring in the corner.

Another example of the congestion prevention part is shown in FIG. 10. Referring to FIG. 10, the guide collar 70 installed in the first compartment is formed at an end of the first compartment 20 so that the second compartment 50 and the second side wall 15 adjacent to the front side are formed. A plate-shaped first guide plate 71 extending in the corner direction formed to meet and a second partition 50 and a second side wall 15 formed at the end of the first guide plate 71 and adjacent from the rear side. The plate-shaped second guide plate 73 extending in the corner direction formed by the meet and the curved support plate extending from the end of the second guide plate 73 and connected to the end of the first partition 20 ( 75).

Guide vanes are also provided at the ends of the second compartments. At this time, the guide feather structure is as described above. The above-mentioned congestion prevention part prevents the generation of the congestion water at the corners of the main body and at the same time effectively prevents the congestion water that may occur in the guide vanes 70 and 80 itself. That is, the first induction plate 71 induces the flow of water in the corner direction of the main body, the second induction plate 73 induces the flow of water in the other corner direction of the main body. And the support plate 75 is formed in a curved shape to function to prevent the generation of stagnant water from the rear of the guide feather (70).

Experimental Example

In order to examine the effect of the flow barrier of the present invention, computational flow analysis was performed at the Institute of Industrial Technology, Sunchon National University.

1. Experimental conditions for flow field and concentration distribution analysis

In order to analyze the flow field and concentration distribution according to the shape of the drift wall in a rectangular water tank with a 20: 1 long width ratio, computational flow analysis was performed for the following three cases.

 As a comparative example, a square water tank without a ditch wall was installed, and a square water tank having a straight ditch wall was used as a first embodiment, and a guide formed at an angle of 45 degrees at the end of the straight drifting wall was a second embodiment. Experiments were carried out on square water tanks with feathers.

Brief shapes of the three cases are shown in FIGS. 11 to 13, respectively. FIG. 11 is a comparative example, FIG. 12 is Example 1, and FIG. 13 is Example 2. FIG. The size of the applied water tank is 25m × 18m × 5m, and the diameters of the inlet and outlet pipes are 0.3m and 0.5m, respectively.

Positions of the inlet and outlet tubes of each water tank are as shown in FIG. 14, and the center of the inlet pipe is 0.35 m in the height direction of the water tank and the center of the outlet pipe is 4.45 m in the height direction. The height of the barrier wall is 2.4m, the thickness is 0.1m, and the width between the barrier wall and the barrier wall is 4.92m. Assuming a water tank capable of supplying 5,000 tons of water for 12 hours, the velocity of the fluid in the inlet was set to 1.641 m / s.

2. Flow Analysis Results and Discussion

15 to 32 show flow analysis results after 240 minutes, 720 minutes, and 1,200 minutes when the disinfectant was supplied from the inlet tube while the water tank was filled with water.

Figures 15 and 16 after 240 minutes in the comparative example, Figures 17 and 18 after 720 minutes in the comparative example, Figures 19 and 20 after 1200 minutes in the comparative example, Figures 21 and 22 after 240 minutes in Example 1 23 and 24 are 720 minutes after the first embodiment, FIGS. 25 and 26 are 1200 minutes after the first embodiment, FIGS. 27 and 28 are 240 minutes after the second embodiment, and FIGS. 29 and 30 are the embodiments 31 and 32 are graphs showing the concentration distribution and the mammary gland after 1200 minutes in Example 2, respectively.

In the case of the comparative example without the convection wall, the flow of the inlet affected the opposite wall surface and the concentration was high at that part, and the flow continued directly to the outlet to ensure sufficient residence time for the disinfectant. It was hard to do. In the case of Example 1 having a straight partition, sufficient retention time of the disinfectant was obtained when compared with the comparative example. For Example 2, a flow phenomenon similar to Example 1 was observed.

The concentration change with time in the outlet pipe is shown in the graph of FIG. In the graph, Case 1 refers to Comparative Example, Case 2 to Example 1, and Case 3 to Example 2. Referring to the result of FIG. 33, in the comparative example, the concentration change in the outlet pipe was the fastest since the retention time of the disinfectant was not secured. This means that the disinfectant is not sufficiently mixed with water and is discharged through the outlet.

In the case of Example 1, the concentration change in the outlet pipe started later than in the comparative example. This means that due to the walls of the disinfectant, the disinfectant is discharged through the outlet pipe after sufficient time for mixing with the water. In addition, after about 400 minutes, the concentration value discharged from the outlet pipe increased more than that of the comparative example due to the sufficient mixing in the water tank. And in the case of Example 2, the concentration change appeared in a similar pattern to Example 1.

Next, the streamline in the water tank for Examples 1 and 2 was compared in FIGS. 34 and 39. 34 and 35 show changes in streamlines of Examples 1 and 2 after 240 minutes, FIGS. 36 and 37 show changes in streamlines of Examples 1 and 2 after 720 minutes, and Examples 1 and 2 after 1200 minutes in FIGS. 38 and 39. And graphs showing the mammary gland changes of 2, respectively.

Referring to the streamline indicated by ○ in FIGS. 34 and 39, in the first embodiment, there was a section in which the flow was stagnant due to vortices occurring between the inner wall and the drip wall of the water tank, but in the third embodiment, the stagnant vortex Was not found.

In the above, the present invention has been described with reference to one embodiment, which is merely exemplary, and it will be understood by those skilled in the art that various modifications and equivalent embodiments are possible.

 Therefore, the true scope of protection of the present invention should be defined only by the appended claims.
