Description

Technical Field

[0001] This utility model relates to the field of ozone removal using corona treatment machines, and more particularly to an ozone removal device using a corona treatment machine. Background Technology

[0002] A corona treatment machine is an industrial device used to improve the adhesion of materials such as plastics, metals, and paper. It alters the chemical properties of the material surface through a physical process called "corona discharge," making it easier for adhesives, inks, and coatings to adhere. During the corona treatment process, oxygen molecules in the air are ionized under the influence of a strong electric field, which in turn generates ozone molecules. As a strong oxidizing and harmful gas, ozone not only causes direct damage to the human respiratory system and skin, but also has adverse effects on plants, animals and various materials in the environment, thus posing a potential threat to the overall ecological environment. Currently, common ozone removal methods on the market mainly include adsorption and catalytic decomposition. Adsorption relies on the pore structure of the adsorbent to physically adsorb ozone. The adsorbent will gradually become saturated, leading to a decrease in efficiency. Moreover, its adsorption capacity is greatly affected by temperature and humidity, so the treatment effect is unstable. After saturation, it must be replaced or regenerated, which is a cumbersome process. Although catalytic decomposition can decompose ozone into oxygen, the airflow distribution and the contact efficiency between the catalyst and ozone in traditional devices may be poorly designed, resulting in some ozone being discharged without being fully decomposed. At the same time, the activity of the catalyst will decay over time. If it cannot be easily monitored and replaced, the treatment efficiency will gradually decrease and the effect will be unstable. These methods generally suffer from low efficiency and unstable treatment results, and the operation is cumbersome and inconvenient when changing catalysts, which increases maintenance costs and work difficulty.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0015] Reference Figures 1-4 An ozone removal device using a corona treatment machine includes a corona treatment machine 1, on which a first collection head 2 and a second collection head 6 are respectively installed. The first collection head 2 is located at the upper end of the corona treatment machine 1, and the second collection head 6 is located at both ends of it, for comprehensively collecting ozone generated during the corona treatment process. The first collection head 2 and the second collection head 6 are respectively connected to a first collection pipe 3 and a second collection pipe 7. The two collection pipes are respectively equipped with a first delivery pump 4 and a second delivery pump 9 for driving gas flow.

[0016] Collection pipe 1 3 and collection pipe 2 7 are respectively connected to placement box 1 5 and placement box 2 8, which contain catalysts that can decompose ozone. Both placement box 1 5 and placement box 2 8 are equipped with filters at the bottom to prevent the catalyst from falling and contaminating the materials. The outer wall of the placement box is provided with a door 13 to facilitate the periodic replacement of the catalyst. The door 13 is fixed by limiting components, including a limiting frame 14 and a limiting plate 15. After the limiting plate 15 is inserted into the limiting frame 14, it is locked by the fixing frame 16 and the fixing pin 17 to ensure that the door 13 is sealed.

[0017] The upper ends of the first collection pipe 3 and the second collection pipe 7 are connected to the exhaust pipe 18 for discharging the treated gas. The second placement box 8 is connected to the first delivery pump 4 through the connecting pipe 12. The connecting pipe 12 is equipped with a connecting valve 10 and a baffle plate 11 for controlling the gas passage.

[0018] It should be noted that the specific models and specifications of the delivery pumps, valves, and catalysts need to be selected and determined based on the actual specifications of the device. The specific selection and calculation methods use existing technology in this field, so they will not be elaborated here.

[0019] The functional principle of this utility model can be explained through the following operation methods: When in use, the ozone generated by the corona treatment machine 1 during operation is adsorbed by turning on the delivery pump 4. The ozone is adsorbed above the corona treatment machine 1 by the collection head 2 and at both ends of the corona treatment machine 1 by the collection head 6 to prevent ozone from overflowing from both ends of the corona treatment machine 1. The ozone collected by the collection head 6 enters the collection pipe 3 through the connecting pipe 12 and is decomposed by the catalyst in the placement box 5. When the corona treatment machine 1 produces too much ozone, the connecting valve 10 is closed by pressing the baffle plate 11, and the second delivery pump 9 is turned on at the same time, so that the ozone collected by the second collection head 6 is discharged from the second collection pipe 7, thereby increasing the ozone adsorption efficiency of the second collection head 6 and preventing ozone overflow. When the catalyst needs to be replaced, pull the fixing pin 17 out of the fixing bracket 16 to release the limit plate 15, then pull out the limit plate 15 to release the limit bracket 14, open the box door 13, and replace the catalyst in the first box 5 and the second box 8.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
