Description

Structural wall structure for storage tank {STRUCTURE OF GUIDING WALL FOR STORAGE TANK}

The present invention relates to the structure of the dike wall for the storage tank, and more specifically, to the flow of water by connecting a round panel or a wave panel made of stainless steel as internal installations such as a continuous round rectangular structure, a wave rectangular structure, and a general water tank. A guide wall structure for directing storage tanks.

Generally, a ditch wall means the wall provided in the inside of a drainage basin so that water may flow without stagnation.

In particular, in the case of a square water tank, water is not smoothly rotated compared to a circular water tank, so the shooter is severe and the dilution performance of the water and the disinfectant is very poor.

In order to secure this point, it is highly desirable that the barrier wall has a long contact time between the water and the disinfectant as the water flows into the 'S' shape inside the storage tank.

By the way, in the construction of the dike wall, the length of extension of the dike wall may be extended as long as necessary without considering economic feasibility or industrial availability, but this is not only very burdensome in construction economy, but also the internal structure of the storage tank is further increased. It has a disadvantage that it becomes dense and the storage capacity which can store water relatively is reduced, and the construction period is very long.

In addition, the conventional flow wall has a disadvantage in that the length of the wall width of the storage tank is limited in increasing the number of the flow wall construction panels in the longitudinal direction in order to increase the extension length thereof.

In particular, in the case of the panel-mounted flow barrier wall, the pressure applied to the panel must be absorbed to the bottom structure side by interposing a panel support shaft between the panel to reinforce the durability of the flow barrier wall. In case of extending the length (the sum of the width of the panel and the diameter of the panel support shaft), the use of the panels and the panel support shaft is not only relatively high, but also the welding points are increased, making the overall construction very difficult.

The multi-stage wave water tank according to the prior art is disclosed in the Utility Model Registration No. 03-0331709 of the applicant, and is a series of water tanks having a continuous rounded rectangular structure of the Patent Registration No. 04-440433. Such a conventional multistage wave water tank has a geometric tank body 1. Here, the wall of the tank main body 1 vertically or integrally bends the upper, lower, left, and right flanges around four of the swelled curved portions, and thus the water pressure of the water is prevented by the wave surface or the round curved surface of the curved portion. It includes a wave panel 2 that disperses and at the same time provides a higher rigidity than the plate flat panel by each flange portion.

The tank body 1 of the prior art does not have a convex wall therein, so that the flow of water is relatively inferior to the cylindrical water tank, similar to a general flat rectangular water tank.

In addition, since the wave panel 2 used in the tank main body 1 is made for a wall only, there is no mention of a method of installing in the form of 'T' coupling at the connection point between the wave panels 2, Difficult to install the ditch wall.

In particular, it should be noted that even in the general rectangular storage tanks together with the tank body 1 of the prior art, the dilution performance of the disinfectant is limited to the extension length of the ditch wall, which is very inferior in economy, workability and weldability. For example, there is a problem that the panel support shaft should be erected at the connection point between the panels, as well as the static 'S' flow of the water flow dilutes the chemical dilution performance, the problem of the reinforcement of the panel for the flow walls during construction, and the panel reinforcement There is a disadvantage that the welding point for the increase.

Accordingly, an object of the present invention is to provide a contact surface with water that is relatively extended by the arc length of the bulged curved portion, although there is no change in the extension length of the wavewall as the wave structure is applied to the wavewall. The long time for contact of disinfectants can be brought, and to provide a wave tank structure for the storage tank that can maximize the dilution performance (CT value) of the drug by giving a wave of water flow.

And, Figure 8 is a perspective view for explaining the structure of the up and down wave storage tank for the up and down wave storage tank according to a modification of the present invention, Figure 9 illustrates the structure of the up and down left and right wave storage tank for the up and down wave storage tank according to a modification of the present invention It is a perspective view for doing so.

As shown in Figure 2, the present invention is a storage tank of the ditch wall structure, such as non-reinforced square wave stainless steel water tank, general rectangular storage, reservoir, storage tank, cylindrical storage tank, water treatment tank, such as reservoir / reservoir, It is applicable to almost all tank bodies 10 for storing and treating fluids.

For example, the ditch wall 100 according to the present invention is installed inside the tank body 10 of the non-reinforced square wave stainless steel water tank.

In more detail, the lower end of the flow wall 100 is welded and fixed to the bottom plate 11 of the tank body 100, and one end of the flow wall 100 has one inner side surface of the outer wall body 12 and It is welded and fixed in a zigzag manner to the other inner side surface.

At this time, the conductive wall 100 has an array type to be described later. In addition, the opposite ends of the welded and fixed portions in each of the flow walls 100 are spaced apart to form a passage 13 between the inner side surfaces of the outer wall body.

The distillation wall 100 installed in this way is obtained through the water inlet pipe 14, and the water (fluid) stored in the tank body 100 passes through the passage 13 spaced apart in a zigzag and drained from the water outlet pipe 15. Guide as much as possible.

That is, after the disinfectant is mixed with water by the disinfectant injector 100 pre-installed in the water inlet pipe 14 or the disinfectant injector pre-installed in the upper plate (not shown) of the tank body 10, It acts as a rectifying wall to suppress the exit to the outlet pipe 15 immediately before dilution.

In this process, the convex wall 100 of the present invention has a curved surface (expansion surface) of the curved portion in a general horizontal plane when compared in the same environment as the straight line distance of a general conduit wall by the following arrangement type and various wave-related structures. As compared with the relatively wide surface, the drip wall 100 of the present invention has a relatively wide contact surface, thereby increasing the contact time between the water and the drug, and eventually increase the dilution performance (CT value) of the drug. do.

For example, the tank body 10 in which the drip wall 100 of the present invention is installed has a passage length that is increased in length relative to the passage length of the general drip wall, and the increased passage length is proportional to the water flow length. do.

Dilution performance has the same meaning as a kind of disinfection ability, it can be expressed by the following equation (1).

CT = residual disinfectant concentration (mg / L) 접촉 disinfectant contact time (min)

Here, the residual disinfectant concentration takes the minimum value of the daily measured residual disinfectant concentration value. The disinfectant contact time, which is the time when water and disinfectant contact each other, should be measured from the initial disinfectant injection point to the water discharge point at the maximum daily flow rate, or to the point where the value of the inactivation ratio is recognized.

In practice, when measuring the contact time of disinfectant, the contact time is the time until 10% of the tracers put into the initial disinfectant injection point to the water discharge point or the point where the value of the inactivation ratio is recognized. do.

However, in case of using the theoretical contact time, the hydraulic residence time according to the structure of the tank main body 10 (the value of the reservoir use capacity divided by the maximum passage flow rate per hour) is multiplied by the conversion factor conversion factor shown in Table 1 below. Calculate the contact time of the actual disinfectant.

In Table 1, the long width ratio corresponds to the ratio of the water flow length and the water flow width inside the tank body 10. If the tank body is difficult to determine the conversion factor according to the long width ratio, the conversion factor can be determined with the approval of a specialized safety management certification authority.The conversion factor of pipeline flow is regarded as 1.0 as a comparison value.

Therefore, if the total wave length of the water flow in the drip wall 100 of the present invention is 20m, the width is 1.5m, the long width ratio is 13.33, the conversion factor of Table 1 is 0.4.

As mentioned above, the larger the conversion factor is, the closer to the tube flow, the longer the contact time of the actual disinfectant, and accordingly, it can be seen that it has very excellent disinfection ability.

As a comparative example, if the same number of conventional ditch walls (straight type) are installed in a general rectangular storage tank according to the prior art, and the total straight water flow length is 14 m and the width is 1.5 m, the long width ratio is 9.33, which leads to the result shown in [Table 1]. The conversion factor is 0.3, and the contact time of the disinfectant is relatively short, so that the disinfection performance is deteriorated.

Hereinafter, the material and the specification of the conductive wall 100 will be described.

The materials used for the conductive wall 100 or the wave conductive wall panel comply with the materials and specifications shown in the table below, but all materials are only those approved by the supervisor and the quality is KS products [STS-444, DUPLEX ( STS329J3L)] may be used with the approval of the construction supervisor if different from the material indicated.

For example, the material properties of the material of the conductive wall 100 are distinguished by the chemical composition of [Table 1], the mechanical properties of [Table 2], and the physical properties of [Table 3].

In addition, each wave conductive wall panel 110 used in the construction of the conductive wall 100 is a unit molding panel (panel), can be produced in the specifications and thicknesses shown in [Table 4], especially the expansion ratio of the curved portion is stored It can be adjusted to correspond to the dilution performance compared to the tank capacity.

As shown in FIG. 3, the wave conduction wall panel 110 used as a construction member in the flow barrier wall 100 of the present invention has a curved portion 111 that is expanded to maintain a curved surface, and an upper end of the curved portion 111. The upper flange 112 is vertically coupled or integrally bent toward the expansion direction of the curved portion 111, and the lower planar vertically coupled or integrally bent toward the expansion direction of the curved portion 111 at the lower end of the curved portion 111 The branch portion 112, the left flange 114 is coupled or integrally bent in any one of the expansion direction or the opposite direction at the left end of the curved portion 111, and the left planar at the right end of the curved portion 111 It has a right flange portion 115 coupled to the branch 114 in the opposite direction or integrally bent.

When the waveguide wall panels 110 and 120 extend in the width direction of the panel, respectively, one of the left and right flange portions 114 and 115 of the waveguide wall panel 110 is different from each other. Is welded to any one of the left and right flanges of the zigzag, wherein the swelling direction of the curved portion 111 is arranged in a zigzag manner in different directions, so that the wave conductive wall panel 110 and the other wave conductive wall panel 120 It is preferable to connect so that the connection shape may have an 'S' shape as a whole.

In this manner, the wave conduction wall panels 110 and 120 extend corresponding to the length of one of the conduction walls, and the last wave conduction wall panel is a predetermined connection point of the outer wall 12, for example, a connection point between the wave panels of the outer wall 12. On one side of the flange is fixed by welding, all the wave guide wall panels (110, 120) are welded perpendicular to the bottom surface. In addition, the upper flange portion or the upper end of all the wave guide wall panels 110 and 120 are welded perpendicular to the upper plate or the upper plate structure of the tank body.

As shown in FIG. 4, when the waveguide wall panel 110 used in the present invention connects the connected left and right flange portions 114 and 115 by welding, the swelling direction of the curved portion 111 is the same. As arranged in the direction, it can be combined to have a continuous '3' shape.
