Description

Cylindrical storage tank with multiple bulkheads {CYLINDER TYPE STORAGE TANK WITH MULTI-BULKHEADS}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cylindrical storage tank having multiple partition walls, which can be used semi-permanently in a place of storing liquids such as water, oil, and the like. It relates to a cylindrical storage tank having multiple partitions to suit.

Generally, the storage tank is made of various materials according to the size and use of the stored media, and has various shapes and sizes in consideration of the economical efficiency with the use place.

For example, a water tank with a product life of about 7 to 8 years is usually small and has a fiber reinforced plastics (FRP) material, and a water tank that can be used for 10 years is made of a material such as sheet molding compound (SMC). It is also made of stainless steel for semi-permanent use.

However, most commercial buildings, such as apartments, or large-capacity water tanks that can be used by a large number of people by storing water or heavy water, are mostly made of concrete or steel plates due to the construction economy.

In particular, the storage water tank used for the advanced water treatment system is a storage tank made of a large-scale rectangular concrete material buried underground, and is used in the advanced water treatment system shown in FIG. 1. In more detail, the conventional rectangular storage tank is a immersion basin for the first to sink the soil, sand and various foreign matters in the raw water drawn up to the intake pump (2), the river water overflow with a rubber beam (1) having an air supply (3), mixed paper 4 and flocculation paper 5 for flocculating impurity agglomerates with agitation apparatus after administration of flocculant, powdered activated carbon, chlorine, etc. A sedimentation basin (6), a sand filter (7) for filtering out fine impurities through the sand layer, an ozone contact (9) for highly purified water supplied through the intermediate pressure pump (8), and a bioactive carbon adsorption basin ( 10) and the water purifier 11 piped with the water feed pump 12.

In particular, the conventional rectangular concrete storage tank used for the purified water (11) 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 adsorption pond (10), It is formed to store for a time (approximately 30 minutes) the chlorine is spread throughout the water, and then supplied to the home through the water pump (13).

That is, the conventional rectangular storage tank is a hexahedron having an empty internal space buried underground, and the water supply pipe 13 penetrates the suction pipe 10 and is provided with a chlorine input device (not shown). And the drain pipe penetrated to the lower portion.

These rectangular storage tanks have the capacity to store tens to hundreds of tons of water at the same time, so that both water supply and drainage occur simultaneously. Therefore, the lower limit of residual chlorine concentration recommended by WHO as chlorine introduced by chlorine dosing device is diluted in water. Phosphorus 0.2 mg / L (0.4 mg / L if more than if there is a risk of contamination by pathogens) will be stored more than tap water.

However, in the case of the Republic of Korea, according to the proposed legislative reform of the Regulations on Drinking Water Quality Standards and Inspection, which was announced by the Minister of Environment on January 8, 2002, the aesthetic discomfort caused by the overdose of disinfectants and the production of disinfectant by-products In order to prevent this, the upper limit of free residual chlorine will be added as drinking water quality standard, and the upper limit of residual chlorine concentration will be set.

There is currently no standard for the maximum content of residual chlorine in water, but in Korea, it is generally managed to maintain 1.0 mg / l to 1.5 mg / l per liter. As a comparative example, the maximum concentration of residual chlorine is 5 mg / l for the World Health Organization (WHO), 4 mg / l for the United States, 1 mg / l for Japan, 5 mg / l for Australia, and the like.

As such, the rectangular storage tank sterilizes water with the residual chlorine concentration mentioned above, and includes the following problems.

That is, in the conventional rectangular storage tank, the time for chlorine to spread throughout the water is designed to be within 30 minutes, so that tap water is discharged to the outlet immediately before the chlorine is sufficiently diluted in water, or tap water that does not have sufficient sterilization time is supplied to the home. Can be.

For example, when tap water with excessive residual chlorine concentration is supplied to the home, it is not suitable for drinking water because of the smell of high chlorine concentration in the tap water, and it is not suitable for drinking water, and it is possible to generate trihalomethane (THM), a carcinogen. 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 there is sufficient exchange of chlorine and water so 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, as shown in Figure 2, in the prior art rectangular storage tank (11 ') of the inner wall surface of the zigzag-shaped flat bulkheads 15 so as to interfere with the flow direction of the fluid to take a long flow of the fluid (f) In some cases, the chlorine and water can be contacted while flowing in an 'S' shape.

In this case, there is an effect that the contact time of water and chlorine in the storage tank 11 'can be relatively long, but a large number of water stagnation portions a to e are formed, where the shooter is made By doing so, there is a disadvantage of worsening the water quality.

In addition, in the water stagnation sites a to e, the water flow is not smooth, so that dilution performance of chlorine, ozone, fungicide, liquid and solid disinfectant and the like is poor.

Accordingly, the conventional rectangular storage tank is difficult to eradicate bacteria, so it is unavoidable to add excessive disinfectant, and an excessive concentration of disinfectant may be combined with an organic material to generate a carcinogen.

In addition, the conventional rectangular storage tank is mostly made of concrete material, causing mold, etc., thereby causing the water quality to fall, and as the end of the product life, acts as a major culprit of water pollution and clean to the consumer The disadvantage is that it does not provide reliability for water.

In addition, when the conventional rectangular storage tank is used in water purification, since most of it is buried underground, there is a disadvantage that it is difficult to maintain and repair, such as immediate response to leakage and inflow of sewage.

In addition, the conventional rectangular storage tank installed in the purified water is buried underground, it is difficult to install or ventilate the manhole, and even if you want to clean the water completely and at the same time to drain all the work, there is an uneconomical disadvantage .

Accordingly, an object of the present invention is to solve the conventional problems described above, by arranging a plurality of cylindrical bulkheads formed in the inlet in the tank, while maintaining a long contact time of water and chlorine, smooth water flow It is to provide a cylindrical storage tank having multiple partitions through which the dilution performance of the drug can be increased.

In the drawings, Figure 3 is a front view for explaining the configuration of a cylindrical storage tank having multiple partitions according to an embodiment of the present invention, Figures 4 to 7 illustrate the manufacturing method of the cylindrical storage tank shown in FIG. It is a perspective view for doing so. 8 is a plan view of the cylindrical storage tank shown in FIG. 3, FIG. 9 is a side cross-sectional view taken along the line AA shown in FIG. 8, and FIG. 10 is a side cut along the line BB shown in FIG. 8. It is a cross section.

As shown in Figure 3, the present invention is a means for storing the storage, such as water, oil, etc., mainly to control the flow of the flow from the inflow to discharge until the discharge, for example, water purification equipment Cylindrical storage tanks with multiple bulkheads used as storage tanks.

Cylindrical storage tank provided with such multiple partitions has a base 101 installed in the ground, a concrete base 102 having a height of 1 m above the base 101, and a cylindrical body 100 standing on the base 102. )

The base portion 102 is provided with a plurality of cleaning tubes 105 penetrating through the respective inner spaces of the cylindrical body 100 and corresponding to the number of the inner spaces, and passing through the central fourth inner space and the drain pipes 106. ) Is implied.

In addition, unlike the tubular body 100, the pipe obtained from the general water tank is installed on the upper side, the water source (10: sorbent) located in a relatively very high position from the ground and the inlet pipe 104 penetrated to the lower side It is. The chlorine injector 20 is piped to the piping facility communicating with the water inlet pipe 104 so that chlorine can be introduced into the water flowing from the water source 10.

The cylindrical body 100 is a storage tank of 900 to 1100 tons of actual water storage capacity having a bottom plate, an outer wall and a top plate having a height of approximately 4 m to 5 m, a diameter of 18 m to 20 m, and an internal volume of 1000 m to 1600 m 3. It has a partition to be described in detail.

For example, the partition wall is arranged in multiples having a ring shape therein and has a multi-cylindrical wall shape of the same height to different heights, or a spiral shape or a vertical diaphragm shape, and the partition wall of the cylindrical body 100 is formed. When installed inside, a chamber of annular or spiral shape is formed inside the main body.

Therefore, in the interior of the cylindrical body 100, the obtained water is sequentially filled in a plurality of chambers divided into respective partitions, thereby controlling the time from the time of acquisition to the time of exiting, and since the shape of the body is also cylindrical, The flow rate can be controlled while smoothing the flow.

Of course, the cylindrical body 100 can be made more compact, and can be manufactured in a large capacity as needed.

In addition, the cylindrical body 100 is fixed to the outer circumferential surface of the outer ladder 107 extending from the upper surface of the base portion 102 to the upper surface of the main body, the handrail 107a erected to a predetermined height along the edge of the upper plate, and each chamber It provides a gas discharge pipe 108 and a manhole 109 formed to correspond to.

In the following, a method of manufacturing a cylindrical storage tank having multiple partitions described above will be described.

As shown in FIG. 4, first, the storage tank installation team installs a concrete foundation and a base 102 and a plurality of plumbing facilities, that is, a cleaning pipe 105 and a drain pipe 106 on the ground. Then, the bottom plate 180 made of stainless steel is placed on the upper surface of the base 102. The bottom plate 180 is provided with a plurality of through holes, that is, a cleaning pipe hole 181, a drain pipe hole 182, and the like at a position corresponding to the plumbing facility.

Thereafter, the installation team moves the lower cylindrical unit 111 to the central upper surface of the bottom plate 180 to construct the first partition wall 110.

The cylindrical unit used in the present invention is integrally bent at the factory and has a flange portion bent integrally at both ends of the tubular body. Such a cylindrical unit is manufactured by the inventor of the Korean Patent Application No. 17648 of the present invention 'flange-type cylindrical unit manufacturing apparatus of the storage tank', it is a structural material for assembling a cylindrical storage tank of about 3m to 20m in diameter having a stainless material. The cylindrical unit forms a plurality of partitions and outer walls through a laminated construction method and a welding construction method.

That is, the welding worker of the installation team uses the welding device 400, double welding the outer circumference portion and the inner circumference portion of the lower cylindrical unit 111 to the upper surface of the bottom plate 180. In such a case, the lower cylindrical unit 111 has a welding line like a solid line and is completely bonded to the bottom plate 180. The bottom cylindrical unit 111 completely bonded in this way has a sealing property that can hold water together with the bottom plate 180.

As shown in FIG. 5, three cylindrical units 112 to 114 are stacked on top of the lower cylindrical unit 111 to form a first partition wall 110 having four stages. Or spot welding) to form a welding line such as a dotted line when welding the flange portions of the cylindrical units 111 to 114. In this case, the cylindrical units 111 to 114 are structurally coupled to one body, but have a structure in which water is not sealed by a welding line such as a dotted line.

This structure can shorten the construction period when structurally joining the cylindrical units (111 to 114) of each end, it is possible to allow water to leak or leak through the air gap between the welding sites.

In particular, the upper cylindrical unit 114 is formed with a plurality of first inlets 119 for water overflow on one circumferential surface, for example, a circumferential surface on the drain pipe 106 side. When the water flows up to the hole position, the first inlets 119 serve to overflow the water, and when the storage tank is designed, the flow rate can be controlled by adjusting the number and diameter of the inlets 119.

The first partition wall 110 is completed by laminating and welding the cylindrical units 111 to 114 at each end.

As shown in FIG. 6, the second partition wall 120 has been described above in a position where the second partition wall 120 maintains a predetermined distance (2.5 m in the case of a storage tank having a diameter of 18 m) as described above. It is constructed in the same way as the construction method. However, cylindrical units 121 having a diameter larger than those of the cylindrical units used in the first partition wall 110 are used, and the second inlet 129 for water overflow in the lower cylindrical unit 121 of the second partition wall 120 is used. Are formed. Here, the position where the second inlet 129 is formed is formed on the circumferential surface of the first inlet 119 side, but may be formed on the opposite circumferential surface in order to bring the flow of water relatively long.

As shown in FIG. 7, the third partition wall 130 and the outer wall body 140 are also fixed perpendicularly to the top surface of the bottom plate 180 while maintaining a spacing of 2.5 m each. Of course, the third inlet 139 for the water overflow is also formed in the upper unit 134 of the third partition 130.

In particular, unlike the first to third partitions 110 to 130, when constituting the outer wall 140, the cylindrical units at each end are double welded, so that the outer circumferential portion and the inner circumferential portion have solid welding lines, thereby providing a complete weld line. Has a sealed structure.

In addition, the outer wall body 140 is wrapped with a heat insulating material 146 such as flame retardant glass fiber, and is finished with a thin plate 147 such as aluminum, thereby having excellent heat insulating performance and a beautiful appearance (see FIG. 9).

When the first to third bulkheads 110 to 130 are vertically fixed to the upper surface of the bottom plate 180 in the interior of the outer wall body 140, the cylindrical bodies 100 of the present invention are divided from the shaft center, respectively, to have a predetermined volume. The first to fourth chambers 118 to 148 capable of storing water in the space of the chamber are formed.

Inside the respective chambers 118 to 148, internal ladders 177 corresponding to the manholes 109 of the upper plate 170 are installed.

In addition, the rib-shaped reinforcement bars 171 and 172 have an axial length corresponding to the gap between the upper portions of the chambers 118 to 148, and are radially disposed on the outer wall body 140 and the first to third partition walls 110 to 130. It is arranged in the direction of and welded to each of the top.

The welded reinforcing rods 171 and 172 increase the structural safety of the outer wall body 140 and the first to third partitions 110 to 130 and serve to support the upper plate 170.

Then, the upper plate 170 is raised and welded. Manholes 109 used as entrances and exits of the chambers 118 to 148 are respectively coupled to the upper plate 170, and rainwater and foreign substances are discharged to the outside while discharging gases generated inside the chambers 118 to 148 to the outside. A plurality of gas discharge pipes 108 having a 'U' tube shape in which the back is not easily introduced into the chambers 118 to 148 are formed.

In addition, the water inlet pipe 104 piped with an external water source penetrates the outer wall 140 to supply water (w / i: water in) to the interior of the fourth chamber 148. At this time, the inner end of the water inlet tube 104 is 'b' shaped discharge tube 104a is piped, so that the water can be supplied in the circumferential direction.

In addition, the inner end of the drain pipe 106 connected to the water pump is projected slightly upward from the axial center of the first chamber 118, so that when the water is filled up to the first chamber 118, the water is It can be discharged to the pump.

In addition, water flow preventing jaws 190 having predetermined lengths and heights are formed in the immediate vicinity of the cleaning tube holes 181 formed in the bottom plates of the chambers 118 to 148, respectively. The water can be easily released to the outside together with the water.

As shown in Figure 8 and 9, the outer ladder 107 is fixed to the outer circumferential surface of the cylindrical body 100, at this time, the welded portion of the outer ladder 107 is the flange portion of the cylindrical units (142, 143) Located at 145.

In addition, since the outer wall body 140 as described above has welding lines 144a and 144b which double-welded the outside and the inside of the flange portion 145, the outer wall body 140 has an excellent watertightness while increasing structural rigidity.

As shown in FIG. 10, the third partition wall 130 similar to another partition wall has a reinforcing rod 171 welded to support the upper plate 170, and a third inlet for water overflow in the upper cylindrical unit 134. Through 139, most of the water in the fourth chamber 148 may be overflowed (g) (see arrows consisting only of solid lines) towards the third chamber 138.

In addition, since the cylindrical units 133 and 134 of the third partition wall 130 form a weld line 134a such as a dotted line by partial welding, as compared with the outer wall side weld line 144b, the portion 134b not welded is formed. Through this, the water of the fourth chamber 148 may flow into the third chamber 138 (h) (see the arrow consisting of a dashed line and a solid line).

In the following, with reference to Figures 7 and 8 will be described how the water is filled in the cylindrical storage tank having multiple partition walls of the present invention.

First, when water enters through the water inlet pipe 104, the water flows into the fourth chamber 148 in the circumferential direction by the shape of the discharge pipe 104a and is smoothly filled while being rotated. The water filled while rotating allows the water and chlorine to mix well with little shooter in the fourth chamber 148. Then, as the water level of the water rises in the fourth chamber 148, the water in the fourth chamber 148 flows into the third chamber 138 through the partially unwelded portion 134b of each end (h). In this case, since the flow rate of the water flowing through the part 134b that is not partially welded is a relatively small flow rate compared to the flow rate flowing through the water inlet pipe 104, the fourth chamber 148 is larger than the third chamber 138. It is filled first. Subsequently, when the water of the fourth chamber 148 is almost full, water flows to the third chamber 138 through the third inlet 139 formed in the upper cylindrical unit 134 of the third partition 130. . In this case, the third chamber 138 is filled with water. On the other hand, since the portion of the second partition wall 120 that is not partially welded with the second inlet 129 is formed at the lower end unit, the water of the third chamber 138 is excessively pressured with the second partition wall 120. It flows into the second chamber 128 without being applied to the third partition wall 130. Subsequently, when water reaches the upper cylindrical unit of the first partition wall 110 after the water is filled in the second chamber 128 and the third chamber 138, the part not welded with the first inlet 119 is removed. It flows inside the first chamber 118 through. Thereafter, the water inside the first chamber 118 exits to the outside through the drain pipe 106.

After the water is obtained through the inlet pipe 104 in this way, the time from the outside through the drain pipe 106 is, for example, in the case of a 900 ton cylindrical storage tank takes about 7 to 8 hours, Cylindrical storage tanks with multiple bulkheads of the invention can provide time for sufficient contact between water and chlorine.

In addition, in the cylindrical storage tank of the present invention, inlets 119, 129, and 139 are formed on only one side of the partitions 110, 120, and 130 arranged in multiple, so that water flows in the circumferential direction and flows first. In the case of the inlet 119 and the third inlet 139, since it is located at a relatively higher position than the second inlet 129, the water in each of the chambers 118 to 148 is changed by the potential energy of the falling water. Flows more efficiently in the circumferential direction.

In addition, the cylindrical storage tank of the present invention pipes each cleaning tube 105 for each chamber (118 to 148), it is possible to clean by section, it is not necessary to discharge the entire water to clean the existing storage tank It is relatively water-saving and easy to clean and manage.

11 is a cross-sectional view for explaining the main configuration of the cylindrical storage tank according to a modification of the present invention, Figure 12 is a side cross-sectional view for explaining the main configuration of the cylindrical storage tank according to another modification of the present invention.

As illustrated in FIG. 11, the cylindrical storage tank having the multiple partition walls of the present invention may be configured to have an inner shape of the partition wall 200 having a spiral shape. In this case, the outer wall body 140 of the cylindrical body 100 is completed by laminating the cylindrical unit described above, and the spiral-shaped partition wall 200 also has a height of 1m and after preparing four strips bent the upper and lower sides By welding the bottommost strip along the spiral marking line marked on the bottom plate in advance, and laminating other strips thereon, the same strip is manufactured at the same height as the outer wall body 140.

Thus, the cylindrical body 100 having a spiral-shaped partition wall 200 can induce the flow of water flowing from the water inlet pipe 104 into a spiral shape, thereby inducing screw flow, and perpendicular to the partition wall 200. In the case of having a horizontal wall 210 having a relatively low height, it is possible to control the flow rate of water.

In another modification of the present invention illustrated in FIG. 12, stepped cylindrical partitions 300 having different heights and arranged in a ring shape are provided in the cylindrical body 100.

For example, the stepped cylindrical bulkhead 300 has a structure in which the height of the step increases gradually from the outside toward the axial center or the opposite side.

Among the cascading cylindrical bulkheads 300 having different heights, the low bulkhead 301 serves to overflow water sequentially when water is filled in the outer chamber without a separate inlet, and the other bulkhead 302 The 303 may form inlets 304 and 305 at the lower side to the upper side, and as a result, when the water is filled up to the inside of the chamber at the axial center, the contact time of the water and the chlorine may be long while rotating in the circumferential direction.

Cylindrical storage tank of the present invention described in detail above can be filled or discharged by reversing the position of the water inlet pipe and the water drain pipe out of the water.

In addition, the cylindrical storage tank of the present invention has a plurality of infrared sterilization lamps 320 are embedded in the inside of the top plate to increase sterilization power and to facilitate the cleaning operation in the dark. The infrared germicidal lamp 320 is electrically connected to an external power source through a switch, so that the germicidal lamp 320 can be turned on / off only when a user desires.

In addition, in the cylindrical storage tank of the present invention, it is possible to form multiple partition walls and outer walls with a concrete material without using a stainless material for construction economy.

As described above, the cylindrical storage tank having multiple partitions according to the present invention is stored while linearly rotating the flow of water to the cylindrical partitions of different diameters installed to have a ring shape therein, the stored water is stored It is possible to keep the contact time of water and chlorine for 7 to 8 hours while overflowing, so that the amount of residual chlorine at the time of discharge can be maintained at a level suitable for 0.2 mg / l, which is the lower limit of the residual chlorine concentration recommended by the World Health Organization. have.

In addition, the cylindrical storage tank having multiple partition walls of the present invention is a cylindrical structure that doubles the structural stiffness by realizing the air shortening by stacking the cylindrical unit formed by integrally bending a strip of stainless material, the shooter generation Water flows smoothly, and corrosion and corrosion resistance are strong enough to minimize water pollution.

In addition, the cylindrical storage tank having multiple partition walls of the present invention is provided with a water flow prevention jaw having a predetermined length and height near the cleaning tube hole, to easily discharge the residues generated during the internal cleaning of the storage tank with water to the outside. Since it can be made, there is an advantage of easy maintenance.

In addition, the cylindrical storage tank having multiple partition walls of the present invention pipes the cleaning pipes for each of the chambers 118 to 148 divided by the partition walls, and does not discharge the entire water to clean the storage tank. It is possible to clean, and accordingly, the water saving effect is relatively easy and the cleaning management is easy.

In addition, the cylindrical storage tank having a multiple partition wall of the present invention has the advantage that it is possible to smooth the cleaning work in the closed space while doubling the sterilizing power by embedding a plurality of infrared sterilization lights.

In addition, in the cylindrical storage tank having multiple partition walls of the present invention, the reinforcing rods are welded to the upper part of the partition wall and the outer wall, the top plate is covered thereon, and a separate pipe valve except the water inlet pipe is installed in the base part.
