Question 2: Which brand of domestic ozone machine is better, including domestic and foreign ones? Please list more for your reference. Should Shanghai Yongle and Suning buy ozone machines? -As far as I know, at present, except the sealed ozone machine of Midea brand has entered the shopping mall, others have either entered or returned, because they cannot be sold at a loss. There are several conditions for the formation of nitrogen oxides in domestic ozone machines. 1 is a mixture of untreated nitrogen and oxygen in the air source, which is a prerequisite; 2. Temperature control of the inner wall of the generator-when the instantaneous discharge continues to work at a temperature of 300 degrees, nitrogen oxides can be generated (of course, no machine can touch this temperature, please note that this temperature is the internal temperature); 3. The generator is located in a humid environment, and there is no drying device, which not only affects the real concentration of ozone, but is also likely to be accompanied by a large number of nitrogen oxides. At present, the control of nitrogen oxides is basically something that companies and manufacturers avoid talking about, and it is actually afraid to talk about the quantity and concentration of ozone without talking about purity. If it breaks down, there will be no business. Ozone has many good uses, but it also needs high purity and low concentration (it meets the disinfection and detoxification standards and will not cause harm to human body).

It is inconvenient to comment on various products. If necessary, you can leave me a message! The quality of household machines varies greatly. Let me tell you something first. For example, there are no machines on Taobao that cost more than 100 yuan, and most of them are built-in glass tubes, so the cost will not exceed 1 cent. The quality difference is really great. Many people buy it cheaply and detoxify it with nitrogen oxides ... The international standard for domestic ozone machines stipulates that nitrogen oxides should not exceed 0.25%, otherwise it will be harmful to people ... Unfortunately, conscientious enterprises cannot exceed this standard.
Question 3: Does the ozone machine have any side effects? What brand of ozone machine is popular now? Correct understanding and suggestions on ozone air disinfection
In the gas phase, the effect of ozone on killing microorganisms depends on these main factors: the threshold concentration of ozone, that is, when the ozone air concentration reaches this concentration requirement, it can have the ability to kill microorganisms; Microbial species; Processing time; Distribution pattern of ozone; Temperature and humidity conditions of the space; Restoration effect of indoor walls, ceilings, floors and other decorative materials.
Under the condition of gas phase, the killing effect of ozone on microorganisms is different. Experiments show that ozone has a strong bactericidal effect on human and animal pathogens and viruses.
Temperature and humidity are the main environmental factors that affect the sterilization effect of gaseous ozone. Generally speaking, the killing effect is good at low temperature and high humidity, and the killing effect can be well reflected when the relative humidity is above 70%. This is due to the increase of relative humidity, which can make the cells swell and the cell wall become thinner, and it is more vulnerable to the penetration and dissolution of ozone.
Toxicity, corrosiveness and safety of ozone: Ozone is a safe gas containing non-toxic substances. When it comes to its toxicity, it is mainly because of its strong oxidation ability. When the concentration is higher than 1.5ppm, people must leave the site, because ozone * * * causes stress reaction of respiratory system, which will cause reversible damage in severe cases. Therefore, the International Ozone Association (IOA) has formulated a health standard: IOA: 0. United States: 0. 1ppm, contact for 8 hours; China: 0. 15ppm, contact for 8 hours.
It is reported in the literature that when the ozone concentration is 0.02ppm, people with sensitive sense of smell can detect it, which is called the sensory critical value, and when the concentration is 0. 15ppm, it is the olfactory critical value, which can be smelled by ordinary people and is also the hygienic standard point. When the concentration reaches 1- 10ppm, it is called * * * range. In fact, the safe use of ozone can completely guarantee people's health from being endangered. Ozone has been used for more than 100 years, so far there has been no death accident caused by ozone poisoning in the world.
In specific use, the ozone disinfection process should be isolated from personnel, and the general ozone generating devices are automatically controlled. As long as the relevant parameters are set, it can be unattended, and spray disinfection of chemical disinfectants is carried out compared with the on-site operation of specially trained personnel, which is more secure for the health of personnel.
Ozone is very oxidizing. Ozone can oxidize many metals, and aluminum, zinc and lead will be oxidized and corroded by ozone, but ferrochromium alloy (stainless steel) containing 25% Cr will not be corroded by ozone.
Ozone has the greatest corrosive effect on ordinary rubber, so corrosion-resistant silicone rubber or rubber products containing preservatives should be used in the application.
Ozone generation is generally powered by high-voltage power supply, so it should be stopped in the presence of conductive gas or hydrocarbon-containing medium, and users must implement it safely according to the operating procedures.
Based on the above factors, we suggest using ozone generator for air disinfection:
Install ozone generator for air disinfection. Separated or moving in a separate space, it is usually placed in a high place, because ozone is easy to fall because of its heavy proportion in the air, and the purpose of placing it in a high place is mainly conducive to the diffusion of ozone; In a relatively closed space, such as a sterile room, a clean room and a space with special requirements for air self-circulation, it is suggested to install an ozone generator in the closed air circulation system, such as being assembled in an air conditioning unit and installed in a main air supply duct or a main return air duct. After reaching the set disinfection time, the air can be disinfected by activated carbon adsorption or catalyst reduction, which can not only achieve the purpose of air disinfection, but also keep the staff from leaving the working environment. At present, the application of this technology in the aseptic room of pharmaceutical industry has been very extensive and mature, and the main workflow is as follows: air compressor-oxygen generator-ozone generator-main air supply pipeline of air conditioner-disinfection and purification area.
Selection and calculation of ozone generator for air disinfection. Ozone disinfection needs to reach at least the threshold concentration. If the generated concentration is lower than the threshold concentration, the sterilization effect will not be achieved, while if the concentration is too high, the operation cost will be increased. Therefore, it is necessary to calculate and select an ozone generating device with a suitable generation concentration range. According to the Technical Specification for Disinfection and the actual application data, the ozone concentration in the clean area of GMP pharmaceutical workshop should be kept at n = 5 mg/m3, 100000 times n = 10 mg/m3,100000 times n = 30 mg/m3,100000 times n = 40 mg. The calculation formula of total ozone consumption is: w = NV/( 1-s), where w- total ozone consumption (mg/m3); S......& gt& gt
Question 4: What brand of ozone generator is better? Guangzhou Lanao has 10 years experience in ozone equipment production, and can customize suitable equipment for different environments, which is more applicable and safer. Welcome to consult.
Question 5: Which brand of domestic ozone generator is better? 1. Ask the manufacturer of Kangjiu disinfection equipment for the configuration suggestion of household ozone generator, because there are too many styles and the words are not clear.
2. The configuration directly affects the performance of the machine.
Question 6: Which brand of ozone oil is better, and which effect of ozone oil is better? By comparison, we know that the main function of ozone oil is sterilization. If the ozone content of ozone oil is less than 7mg/L, the sterilization effect is not ideal. In addition, it depends on the extraction technology of ozone. If electrolyzed, it also contains carcinogens. These two points are important factors in choosing ozone oil.
Question 7: I want to buy an ozone machine. Where can I buy it and what brand is easy to use? Jincheng C3 indoor air treatment equipment is good, with ozone and negative ions, and the operation is very simple, which is very suitable for home use.
