Description

Technical Field

[0001] The utility model belongs to the technical field of ozone production, and in particular relates to an ozone generator protection device. Background Art

[0002] An ozone generator is a device used to produce ozone gas. Ozone is easy to decompose and is difficult to store except for a short period of time under special circumstances. It needs to be produced on site and used on site. Therefore, an ozone generator is required in all places where ozone can be used. Ozone generators are widely used in drinking water, sewage, industrial oxidation, space sterilization and other fields.

[0003] In the prior art, when an ozone generator is used to generate ozone for sterilizing water, a jet pump is usually used in conjunction with a venturi tube to form a gas-liquid mixing mechanism, and the ozone generated by the ozone generator is mixed into the water. After the gas and liquid are fully mixed, the water quality is sterilized. However, when the gas-liquid mixing mechanism stops running, the water in the gas-liquid mixing mechanism may flow back into the ozone generator through the ejector and the ozone delivery pipe, thereby damaging the ozone generator. Utility Model Content

[0011] Compared with the prior art, the ozone generator protection device of the utility model has the following advantages:

[0012] (1) The water sealer is used to prevent water from entering the ozone generator along the ozone delivery pipeline when backflow occurs, thereby protecting the ozone generator circuit from short circuit due to water ingress;

[0026] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0027] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0028] Example 1

[0029] The following is combined with Figure 1 -Attached Figure 5 To further describe the utility model, an ozone generator protection device, such as Figure 1-Figure 5 As shown, it includes an ozone delivery main pipe 1, which is connected to a tee 2, one end of the tee 2 is connected to an ozone outlet pipe 3, and the other end is connected to a connecting pipe 4, a solenoid valve 401 is installed in the connecting pipe 4, the air outlet of the connecting pipe 4 is connected to a water seal 5, the top of the water seal body 501 is connected to the exhaust gas inlet pipe 7, and the top of the water seal 5 is connected to the ozone decomposer 6 through an air guide pipe.

[0030] like Figure 1-Figure 4 As shown, the water seal 5 includes a water seal body 501, an overflow port 502 is provided at the upper end of the side wall of the water seal body 501, a water supply pipe 504 is installed below the overflow port, a sewage outlet 503 is provided at the lower end of the water seal body 501, and a sewage valve is installed on the sewage outlet 503.

[0031] like Figure 1 As shown, an exhaust port 601 is provided at the bottom end of the ozone decomposer 6 , and an exhaust valve is provided in the exhaust port 601 .

[0032] like Figure 1 and Figure 3 As shown, an observation window (8) is installed on the side wall of the water seal body 501, and a water level scale is arranged along the height direction on the side facing the observation window.

[0033] like Figure 1 and Figure 2 As shown, a one-way valve 9 is installed in the ozone delivery main pipe 1.

[0034] The working principle of the ozone generator protection device of the utility model is as follows: when sterilizing water, the solenoid valve 401 is closed, and the ozone generated by the ozone generator is transported out through the ozone transport main pipe 1, and then transported to the gas-liquid mixing mechanism through the three-way 2 and the ozone outlet pipe 3, so that the ozone and the water body are fully contacted and mixed to achieve the disinfection effect. Before the gas-liquid mixing mechanism stops running, the solenoid valve 401 is opened, and then the ozone generator is closed. When backflow occurs, the backflow liquid will enter the water seal 5 through the connecting pipe 4, and at the same time cooperate with the one-way valve 9 in the ozone output main pipe 1 to prevent the backflow water from entering the ozone generator and damaging the equipment circuit.

[0035] At the same time, the excess ozone recovered in the tail gas intake pipe 7 can enter the ozone decomposer 6 through the water seal 5, thereby preventing the ozone from being discharged into the air. The ozone decomposer 6 is filled with an ozone reducing agent, which can reduce the ozone into oxygen and then discharge it through the exhaust port to achieve zero ozone emissions.

[0036] The above are only preferred embodiments of the present invention, and are not intended to limit the present invention in other forms. Any technician familiar with the profession may use the technical contents disclosed above to change or modify them into equivalent embodiments with equivalent changes for application in other fields. However, any simple modification or equivalent change made to the above embodiments based on the technical essence of the present invention without departing from the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
