Description

[0001] APPARATUS FOR MANUFACTURING STERILIZING WATER [0002]

More particularly, the present invention relates to a diluting type sterilizing water producing apparatus capable of precisely measuring and diluting a disinfectant at a desired concentration for each use, To a diluting tank for pumping sterilizing stock solution by using a metering pump for adjusting the pumping amount.

In general, sodium hypochlorite (NaOCl) is used in water treatment plant, disinfection device of sewage treatment plant, cooling water boiler of general chemical plant, desalination process water, cooling water treatment of power plant, drinking water treatment, plants and vegetables, It is a chlorine-free disinfectant in the form of a colorless transparent liquid having strong chlorine odor which is used as washing and papermaking and household bleaching agent.

The non-diaphragm sodium hypochlorite generator used to produce such sodium hypochlorite is 28-30% of the total amount of sodium hypochlorite produced by precipitating a large amount of salt in water, Diluted salt water, in which a certain amount of saturated salt water is melted and saturated and mixed at a pressure of 2.8-3.0% by mixing through a pump and the like, is introduced into an electric furnace having a series of electrodes (anode and cathode) The salt in the diluted salt water is electrolyzed by the DC voltage applied to both sides of the electrode in the process of passing through the decomposition tank.

That is, 2.8-3.0% diluted brine introduced into the electrolytic unit is dissociated into sodium ion (Na +) and chlorine ion (Cl-), and the chlorine ion is oxidized in the anode to become chlorine (Equation 1) (NaOH, caustic soda) and hydrogen (Equation 3) after the sodium produced is reacted with water, and the chlorine produced in the anode and the chlorine Sodium hydroxide reacts to produce sodium hypochlorite (NaCl) (Equation 4).

Cl- > Cl2 + e- < - >

Na + + e- - Na - (2)

The sodium hypochlorite produced as described above is a safe form of salt water and is used as chlorine disinfection or oxidizing agent in the field where disinfection or oxidation is required. The production amount and content concentration of sodium hypochlorite are according to Paradee's law, The amount and the concentration of sodium hypochlorite are determined according to the mixed diluted saline solution.

FIG. 1 schematically shows a configuration of an apparatus for generating sodium hypochlorite according to the prior art. This sodium hypochlorite generating apparatus includes a salt water storage tank 10 in which salt is precipitated in water and an electrolytic bath 20 having a series of electrodes (an anode and a cathode), as shown in FIG. 1, 10 and the electrolytic bath 20 are connected to a brine supply pipe 11 for supplying the brine to the electrolytic bath 20.

The brine in the brine storage tank 10 is connected to an inlet water supply pipe 12 through which the brine is supplied to the electrolytic bath 20, . A flow meter 14 and a flow rate control valve (not shown) are mounted on the brine supply pipe 11 and the incoming water supply pipe 12.

In the sodium hypochlorite generating apparatus constructed as described above, when the brine is supplied through the brine supply pipe 11 in the salt water storage tank 10 and the incoming water is supplied through the incoming water supply pipe 12, the brine is partially diluted And this diluted brine (brine 1: inlet water 10) is transferred to the electrolytic bath 20.

At this time, in the process of passing through the electrolytic bath 20 having a series of electrodes (anode, cathode), electrochemical decomposition and recombination of the diluted brine are caused by the DC voltage applied to both sides of the electrode, And is discharged through the sodium hypochlorite discharge pipe 13 connected to the upper side of the electrolytic bath and stored in a predetermined place.

Sodium hypochlorite stored in a certain place is mixed with a certain amount of water according to the amount of chlorine required in use.

However, in the sodium hypochlorite generating apparatus having such a structure, an electric opening / closing valve, a pressure reducing valve, or a flow rate adjusting valve is installed in the pipe which is branched from the water conduction or the piping where the existing water pressure is formed, In this case, when the pressure in the piping changes, the flow rate and pressure of the incoming water flowing into the electrolytic bath also fluctuate. Therefore, the concentration and production amount of sodium hypochlorite generated in the electrolytic bath are different, The electrolytic apparatus is heated and damaged due to overheating. In addition, when the electrolytic apparatus is in operation, when the electrolytic apparatus is shut down, the opened electric opening / closing valve is not closed and the inlet water is continuously supplied to the electrolytic apparatus The concentration of sodium hypochlorite stored in the storage tank is lowered, There is a problem that flood the bath.

In addition, the electrolytic bath is installed between the outlet of the inlet water supply pump and the use pipe of the sterilized water in order to dilute a certain amount of sodium hypochlorite discharged from the electrolytic bath to obtain a chlorinated water of a desired concentration in response to the object of the object to be cleaned A flow control valve and a solenoid-type electromotive valve are connected in series, so that it is inconvenient to individually control the flow control valve according to the purpose of the disinfectant.

When the sodium hypochlorite outlet of the electrolytic bath is connected to a separate sodium hypochlorite storage tank, a pump for supplying sodium hypochlorite is installed separately between the sodium hypochlorite storage tank and the piping used for sterilized water, There is an inconvenience that the supply amount of sodium hypochlorite should be controlled in response to the increase in the production cost of the product due to the installation of the separate sodium hypochlorite storage tank and the pump.
