Description

Water Tank for Water Storage {water tank}

The present invention relates to a water tank for cylindrical constant storage having multiple ultrasonic sterilizers, which can be used semi-permanently in a place of storing liquids such as water, and is particularly suitable for disinfecting and storing water, such as a purified water of an advanced water treatment system. It relates to a water storage tank for constant storage configured to.

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, product lifespan is 7? Water tanks that are about 8 years old are usually made of a small size, FRP (Fiber Reinforced Plastics) material, and water tanks that can be used for 10 years are made of the same material as SMC (Sheet Molding Compound). It is also made of stainless steel. However, most commercial buildings such as apartments, or large-capacity water tanks that can be used by many people by storing water or heavy water, are mostly made of concrete or steel plates in terms of construction economy, and the structure is also hexahedral.

In particular, the storage water tank used in 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. Conventional rectangular storage tank is a rubber bore equipped with an air supply, and the river water overflow, and the first sinking soil, sand and various foreign substances in raw water pulled up with a water intake pump, flocculant, powdered activated carbon, chlorine, etc. The mixed paper and flocculation paper which flocs impurity into the apparatus, the sedimentation basin which precipitates various impurities and overflows only clean and clean water, the sand filter paper which filters fine impurities through the sand layer, and the intermediate pressure pump It is used for ozone contacting paper for high-purity water treatment, biological activated carbon adsorption paper, and purified water pipes connected to water pumps. In particular, the conventional rectangular concrete storage tank used for purified water is supplied with chlorine-injected water from the sorbent for the purpose of sterilizing various bacteria that may be contained in the filtered water, and the chlorine is spread throughout the water. It is configured to store for a mixing time (approximately 30 minutes) and then to the home via a water pump. That is, the conventional rectangular storage tank is a hexahedron having an empty internal space buried underground, and the water supply pipe which penetrates the sorbent and has a chlorine input device (not shown) is piped on the upper portion, and the water supply pump and the drain pipe which penetrate the lower portion. It has a form piped to it. 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 at the same time. 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, it is necessary to prevent the aesthetic discomfort caused by the overdose of the disinfectant and the production of disinfectant by-products. There is currently no criterion for the maximum value of residual chlorine content in water, but in Korea it is generally 1.0 mg / l? It is managed to maintain about 1.5mg / ℓ. 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 can be supplied to the home. Can be. For example, if tap water with excessive residual chlorine concentration is supplied to the home, it is not suitable for drinking water because of the smell of a high residual chlorine concentration in the tap water, and there is a possibility of generating trihalomethane (THM), a carcinogen. An accident may occur that provides a user with water containing large, 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.

In the rectangular storage tank of the prior art, zigzag-shaped flat bulkheads protrude to the inner wall surface so that the flow of the fluid can be long by interfering with the flow direction of the fluid, so that chlorine and water can be contacted while flowing in the 'S' shape. There may be a case. In this case, there is an effect that the contact time of the water and chlorine in the storage tank can be relatively long, but a large number of water stagnation sites are formed, where the shooter is made, which has the disadvantage of deteriorating the water quality. have. In addition, since the water flow is not smooth at the water stagnation site, dilution performance of chlorine, ozone, disinfectant, liquid and solid disinfectant 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 deteriorating the water quality, and as the end of product life, acts as a major culprit of water pollution and at the same time clean water to consumers There is a disadvantage that does not provide reliability for. 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 .

The present invention has been made to solve the above-mentioned problems, and the linear flow of the water to the cylindrical independent partitions of different diameters while storing the linear flow, and the stored water flows through the partitions 7? It is intended to provide a water tank for constant storage, which can be taken for 8 hours and can maintain the amount of residual chlorine on discharge at a level suitable for 0.2 mg / l, the lower limit of residual chlorine concentration recommended by WHO.
