Introduction of ozone generator for space disinfection

    In the gas phase conditions, the effect of ozone killing microorganisms depends on these main factors: ozone threshold concentration, that is, when the ozone air concentration reaches this concentration, it can have the ability to kill microorganisms; microbial species; treatment time; ozone distribution mode; temperature and humidity conditions in the space; reduction of indoor walls, ceiling, floor and other decorative materials Sexual influence, etc.

Under the gas phase condition, the killing effect of ozone on microorganisms is different. Experiments show that ozone has a strong bacteriolytic killing effect on human and animal pathogenic bacteria and viruses.

The main environmental factors affecting the germicidal efficacy of gas phase ozone are temperature and humidity. In general, low temperature and high humidity have good killing effect, and the relative humidity is more than 70%. This is due to the increased relative humidity of the cell wall, which makes it easier to dissolve.

Ozone toxicity, corrosiveness and safety explanation: ozone is a safe gas of non-toxic substances. Its toxicity is mainly due to its strong oxidation ability. When the concentration is higher than 1.5ppm, people have to leave the site. The reason is that ozone stimulates the respiratory system, causing stress response of the respiratory system and serious reversible injury. Therefore, the Ozone Association (IOA) has formulated the health standard Standard: Ozone Association: 0.1ppm for 10 hours; USA: 0.1ppm for 8 hours; China: 0.15ppm for 8 hours

When the ozone concentration is 0.02ppm, the olfactory person can detect it, which is called the sensory threshold. When the ozone concentration is 0.15ppm, it is the olfactory threshold. Most people can smell it, which is also the health standard point. When the concentration reaches 1-10ppm, it is called stimulation range. In fact, the safe use of ozone can ensure that people's health is not endangered. Since ozone has been used for more than 100 years, there has been no death caused by ozone poisoning.

In the specific use, ozone disinfection process should be separated from personnel, and all the ozone generating devices are automatically controlled. As long as the relevant parameters are set up, it is possible to achieve unattended duties. This is more reliable for the health of personnel than chemical disinfectant spray disinfection requires on-site training of specially trained personnel.

Ozone has strong oxidizability, ozone can oxidize many metals, aluminum, zinc, lead and ozone contact will produce oxidation corrosion, but the chromium iron alloy (stainless steel) containing 25% Cr is basically not subject to ozone corrosion.

Ozone is highly corrosive to common rubber, so it is necessary to use corrosion-resistant silicone rubber or rubber products added with corrosion-resistant agent in application.

Generally, high voltage power supply is used for ozone generation, so it should not be used in the environment with conductive gas or hydrocarbon medium, and the users should implement it safely according to the operating procedures.

Considering the above factors, we suggest that the ozone generator for air disinfection should be used as follows:

Installation of ozone generator for air disinfection. When separate or mobile type is placed in a separate space, it is generally placed at a high place, because the proportion of ozone in the air is large and easy to drop. The purpose of placing at a high place is mainly to facilitate the spread of ozone. In relatively closed space, such as sterile room, clean room and special space with air self circulation, it is recommended to install ozone generating device in closed air circulation system, such as assembly In the air conditioning unit, installed in the main supply air duct or the main return air duct, after reaching the set disinfection time, use activated carbon adsorption or catalyst reduction for air disinfection and sterilization, which can not only achieve the purpose of air disinfection, but also make the staff do not have to leave the working environment. At present, this technology has been widely used in aseptic room of pharmaceutical industry.

Ozone generator for space disinfection

Product overview:

Zhongjing ozone generator is a new generation of ozone generator. Its core components are high dielectric constant discharge body, micro gap high frequency silent discharge form, external double water cooling structure, which improves the concentration and stability of ozone. It can be used by connecting with clean low dew point compressed air.

Zhongjing ozone power supply adopts high-frequency frequency conversion digital frequency modulation inverter technology and is equipped with original high-power drive module. The equipment control system adopts the digital intelligent programming mode to realize the online detection of operating conditions, and adopts the intelligent CPU integrated control mode to protect the equipment operation status and fault self inspection alarm. Ozone production, concentration and operation time can be adjusted at will. The CPU can be upgraded, compatible with industrial PC, easy to integrate control and other functions into one. The equipment configuration is optimized, the volume and weight of the whole machine are greatly reduced, and the energy consumption and investment cost are reduced.

Application fields:

Pharmaceutical, food, aquatic products, aquaculture, purified water, tap water, electronics, incubator, cold storage, aseptic processing workshop, storage, cosmetics

It is widely used in chemical industry, air treatment, water treatment and inside of closed pipes and containers. Used for all kinds of small and medium-sized products

Water treatment engineering (disinfection, sterilization, oxidation, deodorization, decolorization) or preparation of ozone disinfection water. Air for various occasions

Disinfection (sterilization in processing workshops of pharmaceutical and food industries) is used for sterilization of closed pipeline containers (reactors and other containers)

Ozone disinfection does not need to add any chemicals, economic and environmental protection, no residue, no secondary pollution.

 

Product features：

 

● The ozone generator is installed outside the purification air conditioning box, with simple structure, easy installation and use. The user provides standard power supply, low dew point (- 45 ℃) clean air and cooling water. The ozone is connected with the air duct of the purification system through the pipeline, and the ozone is diffused to each clean room for sterilization by the purification circulating air.

● The high-voltage power supply and discharge chamber are integrated and modularized to avoid the failure of single discharge unit.

● The equipment is small in size, simple after the festival and convenient in maintenance.

● It can be equipped with man-machine interface and ozone concentration printer, which can print parameters in real time and time.

● Ozone outlet concentration, environmental application concentration, disinfection start time and disinfection end time, etc.

● It can communicate with the owner's DCS to realize remote control.

● The mode of multi fume hood sharing is adopted, and multiple air conditioning systems can share one ozone generator.

● It can be equipped with N + 1 ozone concentration sub controller to detect the environmental ozone concentration in each clean area in real time.

● The ozone concentration of each fume hood system can be set arbitrarily to automatically maintain the ozone concentration required by each space.
