Ozoneized Water Manufacturing System with High Efficiency

The present invention relates to a high efficiency ozone sterilizing water production apparatus. More specifically, the present invention may control the voltage and frequency of the ozone discharge tube load power source to generate stable ozone (ozone concentration and generation amount), and then use the ozone gas as it is, and also use the ozone gas mechanically based on the Bernoulli principle. The present invention relates to a high-efficiency ozone sterilizing water production apparatus capable of supplying ozone sterilizing water by mixing tap water and ozone in an optimally designed venturi injector.

Ozone is an unstable gas, which is highly chemically active, causing chemical reactions with bacteria, viruses, fungi, odors, and other harmful substances in the air and water, and organic substances (solvents, pesticides, heavy metals, etc.) that are harmful to the human body. Let's do it. This property is used to make air or water clean and sterilized.

In the case of E. coli, ozone has a sterilization rate three thousand times faster than chlorine, and water treatment with ozone is recommended because it retains 25 times the virus sterilization power of conventional chlorine and is not persistent.

Conventional ozone water production method was an acid method of directly injecting the generated ozone gas into the water as shown in Figure 1, the majority of ozone, a poorly soluble gas is exhausted into the atmosphere, not only decrease the ozone dissolved efficiency, but also into the atmosphere The released ozone has harmful effects on the human body, such as difficulty breathing and headaches.

In order to solve the above problems, 'Ozone water production apparatus' published in the Utility Model Publication (Publication No. 1998-026575) or 'Ozone water generation device' invented in the Registration Utility Model Publication (Registration No. 20-0192903) There was a back.

As shown in FIG. 2, the ozone water production apparatus includes an air pump for introducing external air, an ozone generator for generating ozone through a ceramic creeper discharger, and ozone in water introduced into an inlet hose. To improve the ozone treatment efficiency by providing an injector to discharge the discharge hose to the discharge hose, and the 'ozone water generator' is an improvement of the 'ozone water generator', and the components of the 'ozone water generator' are optimized. Placed in position and adding an ozone water mixer to provide a more stable device for producing ozone water.

However, the ozone water production apparatus and the ozone water generator have improved ozone treatment efficiency, but the ozone generating characteristics of the small ozone generator used in the apparatus react sensitively depending on the amount of gaseous feed. These devices are designed to mimic the products of Japan, France, etc .. The ozone generation performance is largely dependent on the amount of input air. This is very anxious. Therefore, serious problems arise, such as unstable ozone dissolved in water and inability to suppress the amount of ozone gas flowing out into the atmosphere to less than the regulation value (0.1 ppm).

The present invention was devised to solve the above problems, and generates stable ozone (ozone concentration and generation amount) by controlling the load power (voltage and frequency) of the ozone discharge tube 90. At this time, ozone can be selectively used in the form of gas and ozone water, and ozone gas having stable characteristics is mixed with water in the venturi type injector 80 which is mechanically optimally designed based on Bernoulli's principle to generate ozone water having stable characteristics. . In addition, the ozone water produced in the injector 80 by mixing the water and ozone repeatedly using the mixing pump 60 has the purpose to maximize the ozone treatment efficiency to generate ozone water having a stable and solid solution characteristic.

Looking at each component of the high-efficiency ozone sterilization water production apparatus of the present invention as described above in detail.

The raw water inlet hose 10 is a pipe into which tap water for ozone water treatment is introduced, and is connected to a raw water supply device such as a faucet.

The raw water inlet hose 10 is provided with a flow switch 100 of FIG.

The flow switch 100 is a device for turning on / off the power of the high-efficiency ozone sterilization water production apparatus of the present invention by detecting the flow of water, the flow switch 100 has a rod-shaped bar magnet moving by the flow of water In addition, a reed switch is provided outside the flow switch 100. When water is introduced through the raw water inlet hose 10 and water above a predetermined pressure flows into the rod magnet inside the flow switch 100, the rod magnet is moved to close the reed switch, thereby turning on the power converter ( Power is applied to 120.

The power converter 120 is a flow of water over a certain pressure flows to the flow switch 100, when the water of a certain pressure flows in the bar magnet inside, the rod magnet is moved, the reed switch is closed (ON) power is turned on Applied device. The power converter 120 is provided with a controller, the controller continuously detects the discharge current of the ozone discharge tube 90 to vary the applied voltage and frequency of the ozone discharge tube (90). Since the load current of the ozone discharge tube 90 varies depending on the temperature inside the ozone discharge tube 90, the amount of inflow air and humidity, etc., the ozone characteristic (concentration) is controlled by varying the applied voltage and frequency by controlling the load current. And the amount of generation) can be obtained. The power converter 120 of the present invention controls the output frequency and voltage of the power supply device to generate ozone by the silent corona discharge generated between the inner conductor 91 and the outer conductor 92 of the ozone discharge tube 90. do.

On the other hand, the power conversion device 120 has a dissolved dissolved touch button 121 is mounted outside the case, the dissolved adjust button 121 adjusts the voltage of the high-frequency high-voltage power supply unit 130, ozone By controlling the voltage applied between the inner conductor 91 and the outer conductor 92 of the discharge tube 90, the desired ozone gas is generated, so that the ozone dissolution is freely adjusted in the range of 0.02 to 1.0 ppm depending on the application. In addition, the power converter 120 includes a passive electrical application circuit that can apply power even when the flow switch 100 is not operated.

The high frequency high voltage power supply device 130 is controlled by the power converter 120 to supply power to the ozone discharge tube 90. In the present invention, a high frequency of several tens of kHz and (several to several tens) kV A high voltage is applied between the inner conductor 91 and the outer conductor 92 of the ozone discharge tube 90 to generate ozone.

On the other hand, when the ozone generated in the ozone discharge tube 90 is used in the form of a gas, the flow switch 100 is not operated, so that the gas-only touch button 122 included in the power conversion device 120 is used. Power is applied to the power converter 120.

The ozone discharge tube 90 is coaxial cylindrical, as shown in FIG. 5, and includes an inner conductor 91, an outer conductor 92, and an insulator 93, and one end of the ozone discharge tube has an air inlet hose 20. ) Is connected and the other end is connected to the check valve 70, ozone gas discharge valve 72 and the ozone gas discharge hose (30).

The inner conductor 91 is an integral type of a rod conductor made of stainless steel and a helical coil surrounding it to maintain durability in ozone having a strong oxidizing power, and an insulator 93 between the inner conductor 91 and the outer conductor 92. Pyrex glass is used. Copper (Cu) tape is attached to the surface of the insulator 93 by the outer conductor 92.

When a high frequency and a high voltage are applied to the ozone discharge tube 90 by the high frequency high voltage power supply device 130, a silent corona discharge occurs, and the air introduced into the air inlet hose 20 causes the ozone discharge tube 90 to flow. When passed, oxygen molecules (O2) are decomposed into two oxygen atoms (O), and unstable oxygen atoms react with oxygen molecules (O2) to generate ozone (O3).

Meanwhile, the air pump 50 connected to the air inlet hose 20 is used to discharge ozone made from the ozone discharge tube 90 to the ozone gas discharge hose 30 in the form of a gas. The valve 72 is turned on.

The outlet is connected to the ozone water discharge hose 40 and the mixing pump 60.

When water flows into the inlet of the injector 80, Bernoulli's theorem results in a faster flow rate at the narrower diameter part and a slower flow rate at the larger inlet and outlet diameters, resulting in a pressure difference as much as the difference in the flow rate. Decreases the internal pressure. Therefore, the ozone gas generated in the ozone discharge tube 90 is introduced into the injector 80 by the pressure difference and is naturally contained in the water introduced into the inlet. At this time, if the amount of inflow of water increases, the internal pressure difference in the injector 80 increases, so that the amount of inflow of ozone gas increases, and the amount of water inflow decreases, so that the amount of ozone gas decreases.

The ozone water discharge hose 40 is connected to the outlet of the injector 80 to discharge the ozone water generated by the injector 80. In addition, the mixing pump 60 is used when ozone impregnated in the water in the injector 80 to be dissolved in the water in the secondary to generate ozone water having a solid solution concentration of more than 99% ozone treatment efficiency.

Ozone gas generated in the ozone discharge tube 90 is introduced into the injector 80 by the pressure difference between the outlet portion, the inlet portion and the intermediate portion of the 80. Ozone water is generated by first injecting the ozone gas into the water in a venturi-type injector 80 that is mechanically optimally designed based on the Bernoulli principle. In addition, ozone sterilization water having a solid solution concentration of 99% or more is prepared by mixing water and ozone secondly by the mixing pump 60.
