Description

Technical Field

[0001] The utility model relates to the technical field of ozone generating equipment, in particular to a high-concentration plate-type ozone generator. Background Art

[0002] Ozone has been widely used in the fields of medical treatment, food processing, water treatment and environmental disinfection. Ozone is a strong oxidant with strong ability to sterilize, disinfect and remove odors. Traditional ozone generators usually use ultraviolet rays or corona discharge to generate ozone, but these methods have certain limitations in terms of ozone concentration and stability. In some application scenarios, high-concentration and stable ozone gas is required to ensure its sterilization and disinfection effect.

[0003] When a traditional ozone generator is operated in an uncontrolled temperature environment, it may cause ozone decomposition and instability, reducing the concentration and sterilization effect of ozone. Therefore, solving how to reduce the gas temperature during the ozone generation process to increase the concentration and stability of ozone has become a key technical issue. Utility Model Content

[0004] In order to solve the above problems, the utility model proposes a high-concentration plate-type ozone generator, comprising a pressure swing adsorber, one end of the pressure swing adsorber is connected to an air supply pipe, one side of the air supply pipe is provided with a cold air box, the air supply pipe passes through the interior of the cold air box and extends to the outside of the cold air box at the other end of the cold air box, and an ozone discharge chamber is provided on the side of the cold air box away from the pressure swing adsorber; a refrigerator is provided on the side of the cold air box, the output end of the refrigerator is connected to the interior of the cold air box, a cold water tank is installed at the bottom of the inner wall of the cold air box, a box to be cooled is arranged above the cold water tank, the box to be cooled and the cold water tank are connected by a connecting pipe, an electric valve is installed on the outer side of the connecting pipe, one end of the cold water tank is connected to two cooling pipes, the two cooling pipes extend to the upper end and the lower end of the ozone discharge chamber respectively, and the other end of the cooling pipe is connected to the box to be cooled.

[0005] Furthermore, a temperature sensor is installed on the cooling box, and the temperature sensor is electrically connected to the electric valve.

[0006] Furthermore, a front tube receiving box is installed between the cold air box and the ozone discharge chamber, and a rear tube receiving box is installed at the other end of the ozone discharge chamber. The front tube receiving box and the rear tube receiving box are used to receive the cooling tubes.

[0009] The beneficial effects of the utility model are as follows:

[0010] 1. The oxygen treated by the pressure swing adsorber is received by the cold air box. The refrigerator works to lower the temperature inside the cold air box, thereby lowering the temperature of the oxygen in the cold air box, lowering the gas temperature, reducing the possibility of ozone decomposition, and converting more oxygen molecules into ozone molecules, thereby increasing the concentration of ozone.

[0011] 2. The cooling water in the cold water tank flows through the cooling pipe to the upper and lower ends of the ozone discharge chamber to reduce the temperature of the environment during the ozone generation process; lowering the temperature helps to slow down the decomposition rate of ozone, making ozone molecules more stable, which is conducive to maintaining high-concentration ozone output for a long time.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0017] The utility model is further described below in conjunction with the accompanying drawings:

[0018] A high concentration plate type ozone generator, such as Figure 1 and Figure 2 As shown, it includes a pressure swing adsorber 1, one end of the pressure swing adsorber 1 is connected to an air supply pipe 2, one side of the air supply pipe 2 is provided with a cold air box 3, the air supply pipe 2 passes through the inside of the cold air box 3 and extends to the outside of the cold air box 3 at the other end of the cold air box 3, and an ozone discharge chamber 4 is provided on the side of the cold air box 3 away from the pressure swing adsorber 1.

[0019] like Figure 1 and Figure 2 As shown, in this embodiment, a refrigerator 5 is arranged on the side of the cold air box 3, and the output end of the refrigerator 5 is connected to the inside of the cold air box 3. A cold water tank 6 is installed at the bottom of the inner wall of the cold air box 3, and a box to be cooled 7 is arranged above the cold water tank 6. The box to be cooled 7 and the cold water tank 6 are connected by a connecting pipe 8. An electric valve 9 is installed on the outer side of the connecting pipe 8. A temperature sensor is installed on the box to be cooled 7, and the temperature sensor is electrically connected to the electric valve 9; one end of the cold water tank 6 is connected to two cooling pipes 10, and the two cooling pipes 10 extend respectively. To the upper and lower ends of the ozone discharge chamber 4, the cooling pipe 10 is arranged in a continuous S shape at the upper and lower ends of the ozone discharge chamber 4, and the other end of the cooling pipe 10 is connected to the box to be cooled 7; a front tube receiving box 11 is installed between the cold air box 3 and the ozone discharge chamber 4, and a rear tube receiving box 12 is installed at the other end of the ozone discharge chamber 4, and the front tube receiving box 11 and the rear tube receiving box 12 are used to receive the cooling pipe 10; a protective cover 13 is installed at the upper and lower ends of the ozone discharge chamber 4, and the cooling pipe 10 is arranged between the protective cover 13 and the ozone discharge chamber 4.

[0020] The working principle of the utility model is as follows:

[0021] The pressure swing adsorber 1 delivers oxygen through the air delivery pipe 2, wherein the pressure swing adsorber 1 plays the role of filtering and drying the oxygen, removing impurities and moisture therein, so that the oxygen subsequently entering the ozone generation link is purer and drier, which is convenient for subsequently increasing the ozone concentration.

[0022] The oxygen passes through the cold air box 3 before entering the ozone discharge chamber 4. The cold air box 3 receives the oxygen processed by the pressure swing adsorber 1. The refrigerator 5 works to reduce the temperature in the cold air box 3, thereby reducing the temperature of the oxygen in the cold air box 3. The main purpose of this step is to reduce the temperature so as to reduce the heat accumulation in the ozone generation process, and it is also beneficial to increase the ozone concentration in the subsequent ozone generation process.

[0023] The cooled oxygen enters the ozone discharge chamber 4, where it is activated by electric shock. Electric shock activation can excite some oxygen molecules to become ozone molecules, thereby generating ozone. This process is to establish an electric field in the ozone discharge chamber 4 and apply enough voltage to cause the oxygen molecules to break down and generate electric shock discharge, thereby stimulating the generation of ozone.

[0024] During the operation of the ozone discharge chamber 4, the cooling water in the cold water tank 6 flows to the upper and lower ends of the ozone discharge chamber 4 through the cooling pipe 10 to reduce the temperature of the environment during the ozone generation process. The cooling water then flows back to the cooling box 7 to be cooled, and the water temperature in the cooling box 7 is reduced by the low-temperature air in the cold air box 3. When the water temperature reaches a specified low-temperature value, the temperature sensor transmits an electrical signal to open the electric valve 9, and the low-temperature water in the cooling box 7 to be cooled flows back to the cold water tank 6. The circulating water keeps the temperature in the ozone discharge chamber 4 at a low level, thereby reducing the possibility of ozone decomposition and maintaining the stability of ozone.

[0025] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
