[0027] The embodiment of the present application will be further described below in combination with the drawings. Embodiment

[0028] As shown in Figure 1 , an adsorption tower for ozone production process comprises:

[0029] A first pipe box 1, the first pipe box 1 is provided with a first support part 11 at the top end, and the first pipe box 1 is provided with a first filling port 12 at the side part;

[0030] A main body 2, the main body 2 is provided with a plurality of heat exchange pipes inside, as shown in Figure 3 , the heat exchange pipes are arranged in an equilateral triangle; the main body 2 is provided with a fixing part 3 at the side part; and

[0031] A second pipe box 4, the second pipe box 4 is provided with a second support part 41 at the bottom end, and the second pipe box 4 is provided with a second filling port 42 at the side part;

[0032] Among them, the number of the first filling port 12 and the second filling port 42 can be one, two or more, and in this embodiment, it is one.
