Description

  The present invention relates to a residual chlorine remover directly connected to a water main plug. In particular, the present invention relates to a residual chlorine remover that can be directly connected to the main plugs of all the water supply pipes for water supply and hot water supply of residential pipes and dechlorinated and dechlorinated from tap water using vitamin C. Furthermore, the present invention relates to a residual chlorine removal method for removing residual chlorine from tap water in all water supply pipes for water supply and hot water supply for residential pipes.

(1) Description of prior art:
Tap water is obligated to mix chlorine to sterilize and disinfect various bacteria, and the Japanese Water Law (Construction Rules for Water Supply Law) in Japan has a residual chlorine content of 0.1 ppm or more in tap water coming out of taps (faucets). It is obliged to maintain the concentration. The amount of chlorine input in each water department throughout the country varies throughout the year. In addition, the amount of chlorine input varies depending on the source of water in large cities, medium cities, small cities, and towns and villages. In addition, the water pressure at each water station is different. In addition, when the amount of water in the water source decreases or the water source becomes dirty due to heavy rain, more chlorine may be added from the viewpoint of hygiene. This increases the degree of chlorine odor and by-products generated by chlorine. In particular, residual chlorine concentrations tend to be high in urban areas and areas close to water treatment plants.

  Various water purifiers are conventionally used as a method for dechlorination / dechlorination from tap water. As a water purifier, for example, a built-in type water purifier, a water tap direct connection type water purifier, a stationary water purifier, a pot type water purifier, and the like are known (for example, see Non-Patent Document 1). In household water purifiers, a method of attaching activated carbon (in the form of granules, powders, fibers, blocks, etc.) to the faucet and diluting a chlorine neutralizer such as vitamin C according to the flow rate of tap water There is known a faucet attached type chlorine remover that extracts and neutralizes tap water. Citric acid, sodium chloride, sodium citrate, potassium phosphate, potassium phosphate, and the like are known as chemical reaction type reaction neutralizing agents that remove chlorine, but the reaction ratio with chlorine in the neutralization chemical reaction is It has not been put into practical use in terms of economy.

  As a conventional first type of drug addition device, a drug addition device is known in which a branch pipe and an outflow pipe are connected in the middle of a water main flow pipe and a drug addition tank is mounted including these (for example, patents). Reference 1).

  In addition, as a conventional second type drug addition device, a drug container and a water passage are provided, a water flow resistance element is provided in the water flow path, and the drug container and the water flow path communicate with the upstream side and the downstream side of the water flow resistance element. A drug addition device provided with holes is known (see, for example, Patent Document 2).

  In addition, as a conventional third type drug supply device, a drug retention part that stores a drug from a drug tank that stores the drug, and a part of the flowing water that flows through the water flow channel are allowed to flow into the drug retention part. There is known a medicine supply device provided with medicine discharge means for discharging medicine (for example, refer to Patent Document 3).

  Furthermore, as a conventional fourth type medicine supply method, a water purifier or a shower head provided with a storage cartridge for storing vitamin C and extracting vitamin C from the cartridge into tap water is known (for example, (See Patent Document 4). In addition, L-ascorbic acid which is the main component of vitamin C can be industrially produced by a combination of chemical synthesis and utilization of microorganisms. The synthesized vitamin C is the same as natural vitamin C (see, for example, Non-Patent Document 2).

(2) List of patent documents:
JP 2003-305357 A JP 2004-97972 A JP 2001-327852 A JP 2005-177726 A Japanese Patent No. 2864183 "Special feature: Enjoying water for drinking", Masayuki Okada, "Air conditioning and sanitary engineering", Vol. 80, No. 3, pp. 23-28, published in March 2006 "New Vitamin C and Health", by Murata Kei, pages 133-135, first published January 20, 1999, Kyoritsu Publishing

However, the conventional apparatus and method for removing residual chlorine have the following problems.
(1) The water purifier of the water faucet attached type chlorine remover is attached to water faucets (including faucets, mixing faucets, spouts, etc.) such as kitchens, toilets, and bathtubs. In a minimum scale house, about 5 taps are provided and about 3 hot water taps are provided. Since a wide variety of hydrants such as a new hydrant and a single lever hydrant are available, it has been difficult to attach a hydrant-attached chlorine remover to a variety of hydrants. For this reason, it was difficult to remove the smell of hot water from all hot water taps and trihalomethane. Moreover, hot water has the property of volatilizing more and more.

  One person drinks about 1 to 2 liters of water per day, whereas the bath needs more than 200 liters of hot water and about 40 liters of hot water to use a shower for 5 minutes. is required. Because a large amount of poison is inhaled in a manner that is highly toxic in the bathroom, human toxicity in the bathroom is 100 to 1000 times higher than in the case of drinking water. That is, chlorine and trihalomethane released into the bathroom are at a much greater risk than drinking tap water. Therefore, it is necessary to take measures for water and hot water used for baths and showers in preference to drinking water. Therefore, develop a small, high-performance residual chlorine remover that can be dechlorinated and dechlorinated from tap water directly connected to the main plugs of all water supply pipes for water supply and hot water supply for residential pipes. It is necessary.

(2) Continuously diluting chlorine neutralizer (vitamin C granule) that can continuously remove residual chlorine from the total amount of water in the water supply and hot water supply of residential piping to neutralize residual chlorine It is necessary to develop a high performance residual chlorine remover that can be removed.
(3) It seems that it is difficult for the conventional 1st type chemical | medical agent addition apparatus to attach a chemical | medical agent addition tank to a water pipe. In addition, when vitamin C is to be applied to this drug addition device, it seems difficult to automatically adjust the reaction amount of the vitamin C solution that undergoes removal reaction with residual chlorine.
(4) It seems that it is difficult to attach a chemical addition tank to a water pipe in any of the conventional second type chemical addition device, the third type chemical supply device, and the fourth type chemical supply method. Furthermore, in the conventional fourth type drug supply method, the supplement period of vitamin C seems to be short.

The object of the present invention is to provide a small, high-performance residual chlorine remover that can be directly connected to the main plugs of all the water supply pipes for water supply and hot water supply in residential pipes and that can dechlorinate and dechlorinate from tap water. There is to do.
Another object of the present invention is to provide a residual chlorine remover that can neutralize and remove residual chlorine in tap water using a chlorine neutralizing agent. In particular, another object of the present invention is to provide a residual chlorine remover capable of neutralizing and removing residual chlorine by continuously diluting vitamin C granules as a chlorine neutralizing agent.
Furthermore, another object of the present invention is to provide a residual chlorine removing method for removing residual chlorine from tap water in all water supply pipes for water supply and hot water supply for residential pipes.

  In the present invention, in particular, “vitamin C” (L-ascorbic acid) is used as a chlorine removal reaction neutralizing agent for removing residual chlorine in tap water. Vitamin C cannot be synthesized in the human body, and is included in 10 vitamins in the supplements 40 of the five major nutrients. From February 1, 1988, the Ministry of Health, Labor and Welfare increased the recommended daily intake of vitamin C from 50 mg to 2000 mg, that is, 40 times. In July 2000, the recommended daily intake of vitamin C was revised to a required amount of 100 mg per day. In this way, the Ministry of Health, Labor and Welfare proposes to supplement daily deficiencies by taking large amounts of vitamin C to make the daily diet more complete.

  On the other hand, experiments at Kyoto University have shown that vitamin B1 is halved when rice is cooked with normal tap water that has not been purified. It is also necessary to purify the tap water when returning dried shiitake mushrooms, dried radish, hijiki, etc. to the normal condition, or when exposing onions or cabbage to water. It is also known that medaka, goldfish, tropical fish, etc. suddenly die in tap water. On the other hand, it is known that if you use water that has been pumped for about a day or water that contains a chlorine neutralizer, medaka, goldfish, and tropical fish swim well.

The chemical structural formula of “vitamin C” (L-ascorbic acid) that shuts down chlorine is shown below.

In the residual chlorine remover of the present invention, residual chlorine in tap water can be chemically decomposed using vitamin C as a reaction neutralizing agent. The chemical reaction formula of the chemical reaction occurring at this time is shown below.

C ₆ H ₈ O ₆ + NaClO → C ₆ H ₆ O ₆ + NaCl + H ₂ O

That is, the above chemical reaction formula indicates that the following chemical reaction occurs.

(Vitamin C) + (sodium hypochlorite) → (oxidized vitamin C) + (sodium chloride) + (water)

As mentioned above, L-ascorbic acid can be produced industrially and the synthesized vitamin C is the same as natural vitamin C.

In this method, the central axis of the inflow pore 158 and the central axis of the outflow pore 159 may be disposed on the central axis 181A of the water pipe 181 and the central axis 182A of the water pipe 182. . In this method, the neutralizing agent 116 is granular vitamin C. The tap water that flows through the drip nozzle pores 148 due to capillary action while the tap water is stopped is continuously diluted with vitamin C in the granules.

  In the method of the present invention, a residual chlorine remover 100 including a neutralizer container 110 containing granular vitamin C is prepared. Next, the neutralizer container 110 is connected to the water supply pipes 181 and 182 through the drip nozzle pores 148. Next, tap water is introduced into the residual chlorine remover 100 to continuously dilute the vitamin C in the granules. Next, the diluted vitamin C is caused to flow into the water pipes 181 and 182. In this method, the diluting step is performed by flowing tap water from an inflow pore 158 provided in the residual chlorine remover 100, and the diluting vitamin C is discharged to the water pipe. It is preferable that tap water is caused to flow out from the outflow pores 159 provided in the chlorine remover 100, and the diameter of the inflow pores 158 is smaller than the diameter of the outflow pores 159.

Capillary phenomenon (Wikipedia) is a phenomenon in which a liquid inside a thin tubular object rises in a tube. In the capillary phenomenon, the height at which the liquid rises in the pipe is determined by the surface tension of the liquid, the wettability of the inner wall surface of the pipe, and the density of the liquid. If the strictness is ignored, the rising height h (unit: m) of the liquid level can be obtained by Equation 1 shown below.

Where T = surface tension (N / m);
θ = contact angle (°);
ρ = density of the liquid (kg / m ³ );
g = gravity acceleration (m / s ² );
r = inner diameter of tube: radius (m).

ここで、Ｔ＝０．０７２８（Ｎ／ｍ）（２０°Ｃ）；
θ＝２０（°）；
ρ＝１０００（ｋｇ／ｍ³ ）；
ｇ＝９．８０６６５（ｍ／ｓ² ）；
ｒ＝管の内径：半径（ｍ）である。 In the case of a combination of a glass tube and water at a sea level, the rising height h (unit: m) of the liquid level can be obtained by Equation 2 shown below.

Here, T = 0.0728 (N / m) (20 ° C.);
θ = 20 (°);
ρ = 1000 (kg / m ³ );
g = 9.80665 (m / s ² );
r = inner diameter of tube: radius (m).

  Using Equation 2 above, it can be seen that in the case of a glass tube having a diameter of 0.1 mm (radius r = 0.05 mm), the rising height h of the liquid level is about 28 cm. For example, when the diameter of the glass tube is 0.3 mm, the rising height h of the liquid level is about 9 cm. Therefore, if the portion where the inner diameter of the pipe is 0.3 mm is 9 cm or more, it is considered that the rising height h of the stop tap water level in the pipe is about 9 cm. Therefore, vitamin C (granule) can be liquefied within the range of this height of rise. In the residual chlorine remover 100 of the present invention, tap water flows from the drip nozzle pores 148 by capillary action, and vitamin C in the granules is diluted to become liquefied vitamin C.

  Referring to FIGS. 1 and 2, the water pressure of the tap water flowing from the upstream side water pipe 181 hits the inlet surface of the inflow hole 158 at a right angle. The tap water pressure of the National Waterworks Bureau is generally an average of 3.5 kgf. When the water main plug is opened, a part of the tap water flowing from the upstream water pipe 181 flows into the blowing nozzle 150 from the inflow pore 158. When part of the tap water flows into the blowout nozzle 150 from the inflow pore 158, the liquefied vitamin C that has already been diluted in the blowout nozzle 150 flows out through the outflow pore 159 to the downstream side. Residual chlorine in the tap water reacts with the liquefied vitamin C flowing out from the reservoir 170 through the outflow pore 159 toward the downstream side water pipe 182 to become oxidized vitamin C and sodium chloride.

  In the method for removing chlorine from the residual chlorine remover 100 according to the present invention, the neutralizer is used in the residual chlorine remover 100 while the water supply pipes for the residential water supply and all the hot water taps for hot water supply are stopped. By capillary action of the container 110, the neutralizer liquefying tube 120, and the drip nozzle pores 148 (hole diameter: 0.3 mm, length: 2.5 mm) provided at the tip of the drip nozzle 140 of the remover unit 130 Depending on the surface tension, the wettability of the wall and the density of the tap water, the height of the tap water rises.

  The principle of the capillary phenomenon in the method of the present invention will be described ignoring the strictness, and the liquid level in the pipe may not be horizontal but may have an inclination in consideration of the wettability of the wall surface. Instead of the surface tension, a force in the direction of shrinking is applied to the liquid surface. The liquid surface having an inclination in the vicinity of the wall surface tends to shrink, and as a result, the water surface is lifted. That is, the force by which the liquid (tap water) rises is equal to the vertical component of the surface tension near the wall surface. The liquid level rises until the force that the liquid (tap water) rises and the weight of the lifted liquid (tap water) balance. The weight of the liquid (tap water) can be obtained by (the density of the liquid × the volume of the liquid), that is, (the cross-sectional area of the pipe × the height of the pipe). However, in the case of a thin tube, this tube cross-sectional area becomes minute. For this reason, the rising height of the liquid level is very large. The height at which the liquid level rises can be calculated using Equation 1 above. For example, in the case of a glass tube having an inner diameter of 0.1 mm, the height at which the liquid level rises is 28 cm. When the diameter of the drip nozzle pore 148 is 0.3 mm, the height of the liquid level can be estimated as 28 cm ÷ 3 = 9 cm.

  When 150 g of vitamin C (granule) is added from the upper part of the neutralizer container 110 as the chlorine neutralizer 116, the vitamin C (granule) passes through the neutralizer liquefier tube 120 and the inner surface of the remover unit 130. The drip nozzle hole 148 is reached from the tapered bore 147 on the inner surface of the drip nozzle 140. In this state, the stopped tap water rises in the drip nozzle pores 148 by capillary action and comes into contact with vitamin C (granule), and liquefaction of vitamin C (granule) begins. When vitamin C (granule) is liquefied, the specific gravity of the liquefied neutralizing agent becomes heavy, and the liquefied neutralizing agent is accumulated at the bottom 154 of the blowing nozzle 150.

  When tap water is used after opening the water tap or hot water tap of the residential water pipe, the water pressure of 3.5 kgf, which is the normal water pressure of the water main (the average tap water pressure of the National Waterworks Bureau), is the residual chlorine remover 100 In the inflow pore 158 of the blowout nozzle 150. In this state, the liquefaction phenomenon (water solubilization phenomenon) of vitamin C (granule) stops, and the liquefied neutralizing agent accumulated in the drip nozzle 140 and the neutralizing agent liquefaction pipe 121 is the drip nozzle of the drip nozzle 140. Blow out from the pores 148. The liquefied neutralizing agent thus blown out is hydraulically induced in the reservoir 170 and blows out from the outflow pores 159. The liquefied neutralizing agent blown out in this manner instantaneously and chemically decomposes residual chlorine in tap water. The action of this reaction decomposition has already been explained with respect to the chemical structural formula.

  According to the method of the present invention, for example, when no tap water is used at night or the like, the water tap is connected between a water meter (meter meter) and a water supply header. When all the 5 taps and 3 hot-water taps in the bathroom, shower, kitchen, washroom, and water heater are closed in the residence, liquefaction (water-solubilization) of vitamin C proceeds in the residual chlorine remover 100 of the present invention. To do. On the other hand, when tap water is used with the water tap or hot water tap open, the capillary action in the neutralizer container 110, the neutralizer liquefying tube 120, and the drip nozzle pore 148 stops, and the water pressure at the normal water pressure of 3.5 kgf Can induce the liquefaction neutralizing agent of vitamin C into tap water to cause a chemical reaction with residual chlorine, thereby removing chlorine from the tap water.

  Therefore, by directly connecting the residual chlorine remover 100 of the present invention to the water tap, there is 0.1 mg to 0.9 mg of residual chlorine per liter of discharged water at the stage of water taps for all water and hot water pipes in the house. When doing so, residual chlorine in the tap water can be almost completely removed.

  According to the present invention, it is possible to manufacture a residual chlorine remover that can continuously dilute a chlorine neutralizing agent to neutralize and remove residual chlorine in tap water. By directly connecting the residual chlorine remover of the present invention to a water tap, residual chlorine in tap water can be removed almost completely. Furthermore, when the method of the present invention is used, residual chlorine in tap water can be neutralized and removed by liquefied vitamin C.
