Benefits of Using Ozone in Waste Gas Treatment
With the rapid development of reform and opening up for decades, China's economy has achieved rapid development. However, the rapid economic development has brought various kinds of damage and pollution to the environment. Ozone technology is currently a relatively advanced disinfection technology, and ozone disinfection has no pollution. Now the country is aware of the importance of environmental protection, and citizens are paying more and more attention to the environmental conditions closely related to their lives. Among them, feed and fertilizer manufacturers have a serious impact on the lives of nearby residents due to the odor generated during the production process. How to deodorize has become the most thorny issue in the production of various feeds. Now many feed manufacturers generally use water spray to remove solid particles in the exhaust gas, but the effect is very limited, and the required effect is not achieved at all. Therefore, choosing a deodorizing device with good effect has become the key to deodorizing.
1. The principle of ozone deodorization: Ozone can quickly decompose substances that produce odors and other odors, such as amines, hydrogen sulfide, methiol, etc., by its strong oxidizing properties. Ozone can oxidize and decompose to produce non-toxic and odorless small molecules substance.
2. Low cost of ozone deodorization: Ozone deodorization relies on the reaction of high-concentration ozone gas and substances that produce peculiar smells. The production of ozone is directly produced by using air as raw material, purifying oxygen, and then using high-voltage electric shocks. Therefore, the cost of using ozone to deodorize is extremely low. Some deodorants use some deodorant liquid, but they are all consumables, and the long-term use is very high.
3. The deodorizing effect of ozone is verified: some people may wonder whether ozone can deodorize. ozone user experience has proved that the deodorizing effect of ozone is very obvious.
Ozone (ozone, O3) is a colorless gas at room temperature, has a special grassy smell, has a strong oxidizing ability, and is extremely stable. It can be decomposed into oxygen at room temperature, and is usually mixed in the atmosphere in a thin state .
Compared with oxygen, ozone has a heavier specificity, is odorous, colored, easily soluble in water, and easily decomposed. Because ozone (O3) is composed of an oxygen molecule carrying an oxygen atom, it is determined that it is only a temporary form. In addition to the oxygen atoms carried, the remaining oxygen atoms are combined into oxygen (O2) into a stable state. Therefore, there is no secondary pollution in the ozone disinfection process, which will send charcoal to the environmental protection needs of mankind. This is the greatest advantage of the application of ozone technology.
The half-life of ozone is only 30-60min. Because it is unstable and easily decomposed, it cannot be stored as a general product, so it needs to be manufactured on site. The concentration of ozone made with air is generally 10-20mg/L, and the concentration of ozone made with oxygen is 20-40mg/L.
Ozone has strong oxidizing properties and is recognized worldwide as a broad-spectrum and highly effective bactericide. Its redox potential in water is 2.07V, second only to fluorine (2.5V), and its oxidizing ability is higher than chlorine (1.36V) And chlorine dioxide (1.5V). Its oxidizing power is twice that of chlorine, and it is 600-3000 times faster than chlorine and 3000 times faster than ultraviolet light. It can destroy the cell wall of decomposing bacteria, quickly diffuse into the cell, and oxidize and decompose necessary for the oxidation of glucose inside bacteria. Glucose oxidase, etc., can also directly interact with bacteria and viruses to destroy cells, ribonucleic acid (RNA), deoxyribonucleic acid (DNA), RNA, protein, lipids and polysaccharides and other macromolecular polymers, making bacteria The metabolism and reproduction process are disrupted. Bacteria being killed by ozone is caused by the breakage of the cell membrane. This process is called cell dissipation. It is caused by the cytoplasm being crushed in the water. Cells cannot regenerate under the conditions of dissipation. It should be pointed out that unlike hypochlorous acid disinfectants, the sterilization ability of ozone is not affected by pH changes and ammonia. Its sterilization ability is 600-3000 times greater than that of chlorine. Its sterilization and disinfection effects occur almost instantaneously. When the ozone concentration in water reaches 0.3-2mg/L, bacteria can be killed within 0.5-1min. The dosage of ozone water needed to achieve the same sterilization effect is only 0.0048% of chlorine. Common Escherichia coli, Streptococcus faecalis, Pseudomonas aeruginosa, Staphylococcus aureus, mold, etc., in an ozone environment for 15 minutes, the killing rate can reach more than 99%.
