Description

Guiding wall of water tank for water treatment

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a flow wall of a water tank for water purification treatment, and more particularly to a flow wall of a water tank for water purification treatment that can prevent generation of stagnant water on a flow path through which water flows.

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. .

This rectangular water tank is capable of storing tens to hundreds of tons of water at the same time, so that water supply and drainage occur simultaneously, and chlorine introduced by the chlorine dosing device is diluted and stored in the water.

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 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 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 between the water and the chlorine in the water tank can be relatively long, but water stagnant water is formed at the inner edge of the water tank or at the corner where the drip wall and the inner wall meet. Shooting occurs.

The occurrence of such stagnant water deteriorates the water quality. In addition, there is a problem in that the dilution performance of chlorine, ozone, disinfectant, liquid and solid disinfectant drugs is poor because the water flow is not smooth at the water stagnation site.

The present invention has been made to improve the above problems, and an object of the present invention is to provide a ditch wall of a water tank for water treatment, which can effectively prevent the generation of stagnant water at corners formed therein.

And the other side of the water tank 10 is formed with an outlet for outflow of water, the outlet pipe 19 is connected to the outlet. Water introduced into the water tank 10 is discharged after staying inside the water tank 10 for a set residence time. The water flowing into the water tank 10 is guided by a ditch wall installed in the water tank 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 ditch wall according to the exemplary embodiment of the present invention includes the first compartments, the second compartments, and the stagnation prevention unit.

In the illustrated example, a plurality of first compartments 20 and second compartments 50 are installed in the water tank 10, and the first compartment 20 and the second compartment 50 are provided. Alternately placed side by side.

Each first compartment 20 extends so that one end thereof is connected to the first side wall 11 of the water tank 10 and extends in the direction of the second side wall 15 opposite 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 in the water tank 10, and the two second compartments 50 alternate with the first compartments 20. Is placed.

Water introduced into the water tank 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 outlet pipe 19, The residence time is greatly extended because the flow paths zigzag along the second compartments 20 and 50 to form a meandering flow path.

The first compartment 20 is formed in the bottom of the water tank 10 at regular intervals to support the top plate, and is installed between the support (21) and a plurality of unit panels (25, 27) ) Are each provided with a diaphragm 23 formed by coupling with each other.

The struts 21 are formed at regular intervals. In the example shown, one first or second ditch wall comprises three struts 21. One strut located at the edge is coupled to the first side wall 11 of the water tank. Of course, the number of the struts 21 can be changed in various ways. Each strut 21 can use a rectangular steel hollow inside.

The diaphragm 23 provided between the struts 21 may be formed at the same height as the strut 21 or lower than the strut 21.

The diaphragm 23 is formed by combining a plurality of unit panels 25 with each other. In the illustrated example, each of the barriers 23 is formed by combining four unit panels with each other. Two unit panels 25 are coupled to the left and right to form a front side, and two other unit panels 25 are coupled to the left and right to form a rear surface. That is, the diaphragm 23 is formed in a double structure.

The unit panel 25 is formed with a coupling portion 26 formed by bending at right and left ends. Coupling portion 26 is coupled to the coupling portion of the side panel or adjacent unit panel of the support (21). In addition, the unit panels 25 positioned on the front and rear surfaces are coupled to each other by the end portions of the coupling parts 26 facing each other. Welding or riveting or screwing by bolts and nuts may be used as the joining method.

Unit panels 25 on the front and rear surfaces are disposed such that the thickness of the diaphragm 23 is equal to the thickness of the struts 21. This is to prevent the loss of water flow by preventing the protruding portion on the front and rear surfaces of the first partition 20 in contact with the flow path.

The support 21 and the unit panels 25 are formed with a coating film 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.

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

Meanwhile, as illustrated in FIG. 6, the first and second compartments may be formed in a waveform in which the diaphragms 41 and 45 are curved back and forth. The diaphragm 41 of the first compartment has a double structure in which two unit panels 43 are joined back and forth. The diaphragm 45 of the second compartment also has a structure in which two unit panels are combined.

And another embodiment of the first compartment 30 is shown in FIG. In the illustrated example, the diaphragm 31 formed between the pillars 21 has a structure in which a plurality of unit panels are coupled to the left and right. Each of the unit panels includes a base plate 33, a first lip 35 protruding from one edge of the base plate 33, and a first lip at an opposite edge of the edge on which the first lip 35 is formed. The second lip 37 is formed to protrude in a direction opposite to the protruding direction of 35). The first lip 35 is joined to the side surface of the second lip 37 or the support 21 of the adjacent unit panel by the bolt 38 and the nut 39. The second lip 37 is coupled to the side surface of the first lip 35 or the support 21 of the adjacent unit panel by a bolt and a nut. The first lip 35 and the second lip 37 are formed with a plurality of through holes 36 into which the bolt 38 is inserted. The base plate 33 of each unit panel is formed to be curved in the opposite direction to the base plate of the adjacent unit panel.
