Description

Dilution device for sterilizing water{DILUTION DEVICE FOR STERILE WATER}

The present invention relates to a device for diluting sterilizing water, and more particularly, to a device for diluting and supplying a disinfectant solution and water used as a sterilizing agent, an oxidizing agent, a bleaching agent, etc. to an accurate concentration suitable for use in various places of use.

In general, sodium hypochlorite (NaOCl) is used in water purification plants, sterilization devices in sewage treatment plants, cooling water boilers in general chemical plants, desalination process water, cooling water treatment in power plants, drinking water treatment, plants and vegetables, meat processing, washing and papermaking in swimming pools. It is a colorless, transparent liquid type chlorine-based disinfectant used for household bleach, etc.

In the non-diaphragm type sodium hypochlorite generator used to manufacture such sodium hypochlorite, 28-30% of salt is melted if a large amount of salt is precipitated in water of a certain amount and pressure, and then maintained for 8 hours or more and within 24 hours. , Saturated salt water of a certain amount and pressure in which the salt is melted is mixed with a pump, etc., to make dilute brine that maintains a salinity of 2.8 to 3.0%, and this is a series of electrodes (anode, cathode) without a diaphragm (ion exchange membrane). The salt in the diluted saline solution is electrolyzed by the DC voltage applied to both sides of the electrode through the process of passing through the electrolysis tank having.

For example, 2.8-3.0% diluted brine introduced into the electrolysis device is dissociated into sodium ions (Na+) and chlorine ions (Chloride, Cl-), and the chlorine ions are oxidized at the anode to become chlorine, and sodium. Ions are reduced at the cathode to generate sodium, and the generated sodium reacts with water to form sodium hydroxide (NaOH and hydrogen, and then chlorine generated at the anode and the sodium hydroxide react to produce sodium hypochlorite (NaOCl). .

Sodium hypochlorite produced in this way is a safe form of brine, and is used as a chlorine disinfection or oxidizing agent at sites that require disinfection or oxidation. The production amount and concentration of sodium hypochlorite follow Faraday's law, and the supplied water and salt water are mixed. The production amount and concentration of sodium hypochlorite are determined according to the diluted brine.

1 is a schematic diagram showing a conventional non-diaphragm type sodium hypochlorite generator.

As shown in FIG. 1, the sodium hypochlorite generator includes a brine storage tank 200 in which salt is precipitated in water, and an electrolysis tank 210 having a series of electrodes (anode, cathode), and a salt water storage tank ( Between 200 and the electrolysis tank 210, a salt water supply pipe 220 for supplying salt water to the electrolysis tank 210 is connected.

In addition, a water supply pipe 230 through which water is supplied is connected to one side of the salt water supply pipe 220, and accordingly, the salt water in the salt water storage tank 200 is partially diluted and supplied when it is moved to the electrolysis tank 210. do.

Here, the salt water supply pipe 220 and the water supply pipe 230 are equipped with a flow meter 240 and a flow control valve 250.

In the sodium hypochlorite generator configured as described above, when brine is supplied from the brine storage tank 200 through the brine supply pipe 220 and the water is supplied through the water supply pipe 230, the brine is partially diluted by water, This diluted brine (brine 1: water 10) is transferred to the electrolysis tank 210.

At this time, in the process of passing through the electrolysis tank 210 having a series of electrodes (anode, cathode), the electrochemical decomposition and recombination of the diluted saline occurs by the DC voltage applied to both sides of the electrode, so hypochlorous acid with an appropriate effective chlorine concentration It is converted into sodium, and is continuously discharged through the sodium hypochlorite discharge pipe 260 connected to one side of the upper end of the electrolysis tank 210 and stored in a certain place.

And, sodium hypochlorite stored in a certain place is used by mixing with a certain ratio of used water according to the desired chlorine demand at the place of use.

Sodium hypochlorite generator with such a structure installs an electric open/close valve, a pressure reducing valve, or a flow control valve in the pipe connected between the water supply or the pipe and the electrolysis tank where the existing water pressure is formed to control the flow rate and pressure of the incoming water. It is a way to control it.

However, in this method, when the pressure in the pipe fluctuates, the flow rate and pressure of the water flowing into the electrolysis tank also fluctuates, so the concentration and production amount of sodium hypochlorite generated in the electrolysis tank are different, and overheating when the quantity is rapidly decreased. As a result, the electrolysis tank is heated and damaged.

In addition, water is continuously supplied to the electrolysis tank that does not operate because the open electric switch valve does not close when the electrolysis tank is in operation, so the concentration of sodium hypochlorite stored in the storage tank is lowered or the storage tank is overflowed. There is a problem.

In addition, a flow control valve installed between the outlet of the water supply pump and the pipe where the disinfectant water is used to obtain the desired concentration of chlorine sterilized water in response to the object to be cleaned by diluting a certain amount of water in sodium hypochlorite discharged from the electrolysis tank, and Since only one solenoid type electric valve is connected in series, it is inconvenient to manually adjust the flow control valve according to the purpose of use of the disinfectant.

In addition, when the sodium hypochlorite outlet of the electrolysis tank is connected to a separate sodium hypochlorite storage tank, a pump for supplying sodium hypochlorite is separately installed between the sodium hypochlorite storage tank and the piping of the place where the disinfectant water is used. There is an inconvenience of adjusting the supply amount of sodium hypochlorite in response, and there is a problem such as an increase in the production cost of the product due to the installation of a separate sodium hypochlorite storage tank and a pump.

Therefore, the sterilization dope supplied from the sterilization dope tank 30 is a sterilization dope piping 31 → a sterilization dope inlet 11 → a sterilization dope inlet pipe 17 → a quantitative control pump 19 → a sterilization dope discharge pipe 18 ) → After passing through the sterilization stock solution inlet (21), while flowing into the inside of the dilator body (25) of the dilator (15), the water supplied from the water pipe (38) is water inlet (10) → water After passing through the feeder 16→water inlet 20, it flows into the inside of the diluent body 25 of the diluent 15.

In this case, the water flow rate and the disinfectant solution flow rate adjusted to a preset concentration may be introduced into the diluent body 25.

Subsequently, the water and the disinfectant solution introduced into the inside of the diluent body 25 generate a vortex by the rotational operation of the rotary orifice 27, and accordingly, water and disinfection inside the diluent body 25 The undiluted solution can be quickly and sufficiently mixed, and the uniformly mixed (diluted) water and the disinfecting undiluted solution, that is, the sterilizing water adjusted to the desired concentration at the place of use, are connected to the sterilizing water discharge pipe 24 and the sterilizing water discharge port 12. After that, it is sent to each use place so that it can be used according to the purpose.

As described above, in the present invention, the disinfectant stock solution is supplied to the dilator through a quantitative control pump capable of controlling the pumping amount by varying the RPM according to various concentration setting values, and in connection with this, the flow rate of water suitable for the corresponding concentration can be adjusted and supplied. By adopting a method of supplying water to the diluent through an existing water supply, the sterilized water of the desired concentration can be produced at each place of use by accurately quantifying and diluting the concentration of the disinfection solution for each purpose.
