[0018] Furthermore, the oxygen production unit of the oxygen generator 2 purifies the oxygen in the dried compressed air to a concentration of more than 92%.

[0019] Furthermore, a drying display device 14 is installed on the pipeline between the outlet of the cold dryer 3 and the compressed air inlet 19 of the oxygen generator 2. The drying display device 14 can display the drying condition of the cold dryer 3 while drying the compressed air discharged from the cold dryer 3 again.

[0020] Furthermore, the drying display device 14 includes a box body and a blue silica gel desiccant 15. A drying inlet and a drying outlet are respectively provided at the upper and lower ends of the box body. The two ends of the drying inlet and the drying outlet are respectively connected to the outlet of the cold dryer 3 and the compressed air inlet 19 of the oxygen generator 2 through pipelines.

[0023] When the utility model is in use, air enters the oxygen generator 2 and is compressed, and then enters the cold dryer 3 after being compressed by the compressor. The air after moisture removal is sent back to the oxygen generator 2. The oxygen generator 2 purifies the oxygen to more than 92%, and the oxygen enters the hydrodynamic cavitation machine. The hydrodynamic cavitation machine dissolves the oxygen in the water in a stable small molecule state. The small molecule oxygen can remain in the water for more than 7 days, so that the treated water is rich in small molecule oxygen; the irrigation water rich in small molecule oxygen enters the soil, which can greatly increase the oxygen content in the soil, is beneficial to the growth of plant roots, is beneficial to the growth of aerobic microorganisms in the soil, and solves the problem of soil compaction.

[0024] Since the equipment of the present patent is used in a farmland, the humidity in the air at the farmland is high, so the moisture content of the air entering the oxygen generator 2 is very high. Once it directly enters the oxygen production unit in the oxygen generator 2, it is very easy to damage the oxygen generator 2, thereby reducing the service life of the oxygen generator 2 and ultimately affecting the service life of the entire equipment. Therefore, the present patent allows the compressed air in the oxygen generator 2 to enter the cold dryer 3 for drying, and the dried compressed air enters the oxygen production unit in the oxygen generator 2 again, thereby protecting the oxygen production unit of the oxygen generator 2, increasing the service life of the oxygen generator 2, and thus increasing the service life of the entire equipment.

The normal color of the blue silica gel desiccant 15 is blue, and it gradually turns into light red with the increase of moisture absorption. When it turns into light red, the blue silica gel desiccant 15 is replaced. , the blue silica gel desiccant 15 can not only dry the compressed air, but also observe the working status of the cold dryer 3. When the light red color development of the blue silica gel color developer is short, it means that the drying effect of the cold dryer 3 is not good. When the color development time of the blue silica gel color developer is very long, it means that the working effect of the cold dryer 3 is very good. Therefore, the final equipment has a long service life. At the same time, the hydrodynamic cavitation machine of this patent includes a water pump and a nano bubble generating device. The nano bubble generating device is a device that can realize the mixing of gas and liquid.
