Abstract

PURPOSE:To allow the permanent purifying of water without using active carbon by respraying at least a part of the clean water after spraying further at least >=once into air. CONSTITUTION:The water entering an inflow pipe 9 is immediately sprayed in the form of fine particles by a spraying nozzle 2 into a tank 5. The residual chlorine, trihalomethane and mold smells in the water evaporate into the air introduced from a ventilation port 3 when the water is sprayed in the form of fine particles. The concn. thereof in the water is thus decreased and such matters flows toward an outflow port 4. The water flowing out of the outflow port 4 is partly sucked up from a branch pipe 7 by a pump 8 and is introduced again into an inflow pipe 9 and is mixed with the fresh water. The mixture is again sprayed. Such operations are repeated a required number of times. Accordingly, to this device, the prescribed amts. of the residual chlorine, trihalomethane and mold smells are removed by the spraying system alone without using active carbon.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to the removal of residual chlorine, trihalomethane and musty odors in water, particularly tap water.

[Conventional technology]

In recent years, residual chlorine, trihalomethane, and musty odor contained in tap water and their toxicity to the human body have become a problem, but currently most methods use activated carbon to remove these substances. In adsorption removal methods using activated carbon, the adsorption capacity of activated carbon is limited, so small volumes are mostly used for household use, and even in that case, the disadvantage is that it takes time and cost to replace the activated carbon.

[Problem that the invention seeks to solve]

In view of the drawbacks of activated carbon as described above, the present invention aims to purify water semi-permanently without using activated carbon.

[Means for Solving the Problems] The gist of the present invention is to provide a water purification device that purifies water by spraying the water and re-spraying a portion of the purified water into the air at least once or more. This is a unique water purification device.

[Function] According to the water purification device of the present invention, residual chlorine, trihalomethane, and musty odor in water are each volatilized into the air at a fixed rate by one spray, and the concentration of each substance after spraying is reduced. By re-spraying a portion of the sprayed water into the air at least once or more, each substance can be reduced to a predetermined concentration.

〔Example〕

Embodiments of the present invention will be described below with reference to FIG.

The main body 1 consists of a tank with a spray nozzle 2 and a ventilation port 3 in the upper part and an outlet 4 in the lower part, and the outlet 4 is connected to the end of a branch pipe 7 which is further connected to a discharge pipe 6 and a branch pipe 7. A pump 8 is connected to the pump 8 and introduces water that has passed through the branch pipe 7 into the inflow pipe 9.

The water entering the inflow pipe 9 is immediately turned into fine particles by the spray nozzle 2 and sprayed into the tank 5. By being sprayed in the form of fine particles, residual chlorine, trihalomethane, and musty odor in the water are volatilized into the air introduced from the ventilation port 3, the concentration in the water is reduced, and the water flows to the outflow port 4. Outlet 4
A part of the water flowing out is sucked up by the pump 8 from the branch pipe 7, introduced into the inflow pipe 9 again, mixed with fresh water, and sprayed again. Such operations are repeated a required number of times. Further, the proportion of water branched to the branch pipe 7 and returned to the inflow pipe 9 is determined by the final removal rate of the harmful substances to be removed. The same applies to the number of times re-spraying is repeated.

Here, FIG. 2 shows an example of the number of times of continuous spraying and the removal rate of residual chlorine, chloroform, 2-M I B, and diosmin.

In FIG. 2, the vertical axis shows the removal rate of each substance, and the horizontal axis shows the number of continuous sprays. In this way, the removal rate per spray differs depending on the type of substance, so the discharge pipe 6 and branch pipe 7
By appropriately changing the ratio of the amount of water flowing into the filter, the average number of times of spraying can be determined to obtain the required removal rate. As described above, according to the water purification device of the present invention, each substance can be reduced to a predetermined concentration by appropriately determining the rate and number of times that water is re-sprayed.

〔Effect of the invention〕

As described above, according to the present invention, the required amount of residual chlorine, trihalomethane, and musty odor can be removed only by a spraying method without using activated carbon.
