Detailed Description
The following detailed description of the embodiments of the present invention will be provided in conjunction with the accompanying drawings to facilitate further understanding of the present invention by those skilled in the art, and should not be construed as limiting the scope of the present invention.
Example 1: referring to fig. 1, a high efficiency ozone water treatment system is characterized in that: the system comprises an air source preparation system, an ozone generator 5, an ozone contact tank 6 and a tail gas destructor 7, wherein the air source preparation system comprises an air compressor 1, an air storage tank 2, a freezing dryer 3 and an adsorption dryer 4 which are sequentially connected through pipelines; an air inlet pipeline 8 is connected between the adsorption dryer 4 and the air inlet end of the ozone generator 5, and an ozone outlet pipeline 9 is connected between the air outlet end of the ozone generator 5 and the ozone contact pool 6; a contact tank water inlet pipeline 10 and a contact tank water outlet pipeline 11 are respectively arranged on the ozone contact tank 6, and a liquid level meter 12 is arranged on the contact tank water inlet pipeline 10; the ozone contact tank 6 is connected with the tail gas destructor 7 through a tail gas discharge pipeline 13, and the tail gas destructor 7 is also connected with a gas discharge pipeline 14.

Under the action of discharge reaction, part of oxygen molecules in the air are decomposed into ozone molecules, so that ozone is generated;
thirdly, the ozone is treated in the ozone contact tank 6, and the specific process is as follows: ozone enters the ozone contact tank 6 through the ozone outlet pipeline 9, water enters the ozone contact tank 6 through the contact tank water inlet pipeline 10, the ozone is in contact with the water to carry out aeration treatment on the water, and the treated water is discharged from the contact tank water outlet pipeline 11. In the water treatment process, residual ozone enters the tail gas destructor 7 through a tail gas discharge pipeline 13, is subjected to concentrated destruction treatment and then is discharged through a gas discharge pipeline 14. The level gauge 12 on the contact tank water inlet pipeline 10 is used for monitoring the liquid level data of the ozone contact tank 6, thereby controlling the water inflow of the ozone contact tank 6 to keep the liquid level stable and avoiding the tank water from being pressed down into the tail gas destructor 7.
Example 2: referring to fig. 2, 3 and 4, in the system for treating high efficiency ozone water according to embodiment 1, the ozone generator 5 includes a horizontal main tank 51, and two ends of the main tank 51 are connected to end caps 52 through flanges; an air inlet cavity 53 is arranged at the air inlet end of the inner cavity of the ozone generator 5, an air outlet cavity 54 is arranged at the air outlet end, and a discharge chamber 55 is arranged between the air inlet cavity 53 and the air outlet cavity 54; plate-shaped ports 56 are arranged at two ends of the discharge chamber 55, and a plurality of discharge units 57 are arranged between the plate-shaped ports 56; the discharge unit 57 comprises a stainless steel tube 571 and a discharge tube 572, an insulating layer 573 is coated on the outer layer of the discharge tube 572, the stainless steel tube 571 is sleeved outside the discharge tube 572 and is arranged concentrically with the discharge tube 572, and a discharge cavity 574 is arranged between the stainless steel tube 571 and the discharge tube 572; a circular hole 561 for fixing the discharge unit 57 is arranged on the plate-shaped port 56, the circular hole 561 is hermetically arranged with the stainless steel tube 571, and the gas inlet cavity 53 is communicated with the gas outlet cavity 54 through the discharge cavity 574; high-voltage distribution bars 58 are arranged in the air inlet cavity 53 and the air outlet cavity 54, and the high-voltage distribution bars 58 are connected with the discharge tubes 572; the air inlet pipeline 8 is connected with the main tank body 51 and communicated with an air inlet cavity 53, and the ozone outlet pipeline 9 is connected with the main tank body 51 and communicated with an air outlet cavity 54; the ozone generator is also provided with a cooling water circulation system, the cooling water circulation system comprises a cooling device 19 and a water tank 20, the cooling device 19 is connected with the upper end of the main tank body 51 through a cooling device water inlet pipe 21, the cooling device 19 is connected with the water tank 20 through a cooling device water outlet pipe 22, the water tank 20 is connected with the lower end of the main tank body 51 through a cooling water pipe 23, and the cooling device water inlet pipe 21 and the cooling water pipe 23 are both communicated with the discharge chamber.

Since the high-voltage electrode passes a high-voltage high-frequency current through the discharge tube 572 via the high-voltage distribution bar 58 and the insulating layer 573 insulates the discharge tube 572 from the stainless steel tube 571, a high-voltage electric field is formed between the discharge tube 572 and the stainless steel tube 571, and a discharge reaction occurs in the discharge cavity 574 to generate an electrostatic current. Under the action of the electrostatic current, part of oxygen molecules in the air are decomposed into ozone molecules, so that ozone is generated and enters the air outlet cavity 54 and is discharged through the ozone outlet pipeline 9. The discharge units 57 simultaneously perform discharge reaction to convert air into ozone, and the ozone production efficiency is high.
The heat generated by the discharge reaction raises the temperature of the discharge cells 57, and the high temperature is not favorable for the generation of ozone but favorable for the decomposition of ozone, resulting in a decrease in the yield and concentration of ozone, requiring a cooling water circulation system for cooling the discharge cells 57. The cooling water in the water tank 20 enters the discharge chamber 55 through the cooling water pipe 23, cools and absorbs heat from the discharge unit 57, and then is discharged into the cooling device inlet pipe 21.

Thin rectangular channels are formed between the plates of the plate heat exchanger, the heat exchange area is large, and the cooling effect is good. The heat of the hot water is absorbed by the cooling medium to be changed into cooling water, and is discharged through the hot medium outlet 192, while the heat of the hot water absorbed by the cooling medium is discharged through the cold medium outlet 194.
Example 4: referring to fig. 1, in the high efficiency ozonated water treatment system according to embodiment 1, a pressure gauge 15 and a dew point meter 16 are installed on the air inlet pipeline 8, an ozone concentration meter 17 is installed on the ozone outlet pipeline 9, and a tail gas detector 18 is installed on the gas discharge pipeline 14.

The aeration disc 622 aerates the water and the purified water is discharged from the outlet pipe 11 of the contact tank. During the water treatment process, a part of ozone cannot be dissolved with water and diffused into the tank body 61. Because the tank body 61 is of a closed structure, residual ozone is collected by the tail gas discharge pipeline 13 and enters the tail gas destructor 7 for treatment. The aeration pipes 63 and the aeration devices 62 may be uniformly installed in the tank body 61, or the number and installation positions of the aeration pipes 63 and the aeration devices 62 may be adjusted according to the water treatment requirements.

The valve on the tail gas discharge pipeline 13 connected with the main engine is a main valve, and the valve on the tail gas discharge pipeline 13 connected with the standby engine is a secondary valve. When the main machine is normally used, the main valve is opened, and the secondary valve is closed; when the main machine is in fault, the secondary valve is opened, the main valve is closed, and the standby machine is used. Two tail gas destructors 7 are provided one for each use to ensure that residual ozone can be treated uninterruptedly.
