How to eliminate ozone odor in corona workshop

In modern industrial production, corona workshops are a common existence, and they play an important role in many fields such as electricity, electronics, and chemical industry. However, a large amount of ozone will be generated during the operation of corona workshops, and the resulting ozone odor will not only affect the working environment, but also may cause harm to the health of workers. Therefore, how to effectively eliminate the ozone smell in the corona workshop has become an urgent problem to be solved.

Reasons for the generation of ozone in the corona workshop

The corona workshop mainly works on the principle of corona discharge. During the corona discharge process, when the air is ionized under high voltage, the oxygen molecules (O₂) in the air will undergo a series of chemical reactions. When the voltage reaches a certain level, the oxygen molecules will be decomposed into oxygen atoms (O), which are very active and will combine with the surrounding oxygen molecules to form ozone (O₃). Its chemical reaction equation can be simply expressed as: 3O₂ → 2O₃. The high-energy electrons generated during the corona discharge process are the key factors that promote the decomposition of oxygen molecules and the generation of ozone. In the corona workshop, due to the continuous high-voltage discharge, this reaction continues to occur, resulting in the large-scale production of ozone.

Hazards of ozone in the corona workshop

Ozone is a highly oxidizing gas. Although it has a certain purification effect on the air at a certain concentration, high concentrations of ozone in the corona workshop bring many hazards.

First of all, it poses a serious threat to human health. Ozone has a strong pungent smell. Inhaling a certain amount of ozone will irritate the respiratory mucosa, causing symptoms such as coughing, shortness of breath, and chest pain. Long-term exposure to high-concentration ozone environments may also lead to decreased lung function and cause diseases such as bronchitis and asthma. In addition, ozone can also irritate the eyes, causing redness, pain, blurred vision, and other problems. According to relevant research, when the ozone concentration in the workshop reaches 0.1ppm, it will produce obvious irritation reactions to the human respiratory tract and eyes.

Secondly, ozone also has a damaging effect on equipment and materials. Due to its strong oxidizing properties, ozone will accelerate the corrosion of metal materials and reduce the service life of equipment. For some polymer materials such as rubber and plastic, ozone will cause them to age and become brittle, resulting in a decrease in material performance and affecting the normal operation of the equipment. In the corona workshop, many precision equipment and expensive materials may be damaged by the presence of ozone, increasing the operating costs of the enterprise. Studies have shown that in an environment with an ozone concentration of 0.05ppm, the corrosion rate of metal materials will be about 20% faster than in a normal environment, and the aging rate of rubber and plastic materials will also increase significantly.

Difficulties in ozone treatment in corona workshops

There are many difficulties in ozone treatment in corona workshops.

On the one hand, ozone has strong diffusivity. Since ozone molecules are small and have certain volatility, ozone will quickly spread to every corner in the workshop, making it difficult to treat it centrally. This makes the distribution of ozone in the workshop relatively uniform, and it is difficult to effectively remove it by simple local collection methods.

On the other hand, the ozone concentration in the corona workshop is usually not low. Since the corona discharge process continuously produces ozone and the space in the workshop is large, ozone continues to accumulate in the workshop and the concentration gradually increases. According to actual monitoring, in some large corona workshops, before ozone treatment, the ozone concentration can be as high as 0.5ppm or even higher. The higher ozone concentration means that more powerful processing capabilities are required to effectively remove it, which increases the difficulty and cost of treatment.

In addition, corona workshops usually require a large ventilation volume to ensure the normal operation of the equipment and the air quality of the working environment. The presence of large air volume speeds up the flow of ozone in the workshop, further increasing the diffusion range and collection difficulty of ozone. Traditional ozone collection equipment often cannot adapt to such a large air volume environment, and it is difficult to effectively collect and treat ozone in the workshop.

How to solve the ozone problem in the corona workshop

The key to solving the problem of ozone treatment in the corona workshop is to develop efficient catalysts and reasonable treatment equipment.

After a lot of experiments and explorations, the research team of Minstrong has successfully developed a highly efficient catalyst. This catalyst has a unique chemical structure and active ingredients, which can quickly decompose ozone into oxygen at low temperatures and pressures. The principle of its catalytic reaction is that the active sites on the surface of the catalyst can adsorb ozone molecules, causing ozone molecules to decompose and generate oxygen molecules. This catalyst has a high decomposition efficiency and can convert a large amount of ozone into harmless oxygen in a short time, greatly reducing the ozone concentration in the workshop. After rigorous testing, the catalyst can achieve an ozone decomposition efficiency of more than 99% under normal working conditions.

In order to better collect and treat the ozone that escapes in the workshop, Minstrong has also developed a special circulating fan. This circulating fan has a strong suction force and a reasonable airflow design, which can effectively collect ozone from every corner of the workshop and transport it to the reaction device equipped with a catalyst for treatment. The working principle of the circulating fan is to circulate the air in the workshop by generating a strong airflow, so that ozone can be continuously sucked into the reaction device and fully contacted with the catalyst, thereby achieving efficient decomposition of ozone.

In practical applications, Minstrong's ozone elimination system has achieved remarkable results. By combining high-efficiency catalysts with circulating fans, the system can quickly and effectively reduce the ozone concentration in the corona workshop, eliminate ozone odor, and improve the working environment. After actual testing, after using this system in a large corona workshop, the ozone concentration in the workshop was reduced from the original 0.5ppm to below 0.05ppm, which is far lower than the national ozone safety concentration standard for workshops, effectively protecting the health of workers and the normal operation of equipment.
