The main function of ozone generator and the choice of gas source

The main function of ozone generator

Disinfection. Studies show that ozone is a broad-spectrum, efficient, fast, fungicide, ozone generator which can quickly kill germs that make human and animal pathogenic viruses and microbes. Ozone is a kind of very strong oxidizing substances, take advantage of its oxidation, can in a short time break biological structure of bacteria, viruses and other microbes, ozone generator to lose the ability to survive. There are many other compounds that use oxidative properties to kill microorganisms to achieve sterilization, such as common chlorine gas, bleaching powder, and potassium permanganate. But these fungicides are not only slower than ozone, but they are also harmful to the human body.

2, detoxification. Ozone can effectively remove toxic gases by oxidation, and ozone generators such as C0, S02, mustard gas, etc. Soluble in water of ozone can effectively remove the water oxidation, decomposition of toxic substances such as heavy metal ions, organic toxicants, cyanide, sulphide and dichlorvos, omethoate, marla acid, etc.

Protect freshness. Due to the bacteria, microbial strong killing effect on ozone, ozone occurs for water treatment of meat and other foods can achieve anticorrosive, eliminate peculiar smell, the effect of preservation. At the same time as ozone produces a large number of negative ions, some negative ions in the air can effectively inhibit the respiration of fruits and vegetables and delay the metabolic process. At the same time, ozone can kill the cause of vegetable and fruit rot pathogen, occurring in the process of decomposition of fruits and vegetables storage have ripening effect of waste products such as ethylene, alcohols, aldehydes, aromatic substances, etc. So, under the effect of ozone and anion of inhibiting the growth of fruits and vegetables of metabolism and microbial pathogen spread, therefore the ageing process by ripe, prevent the rot, achieve the result of keeping fresh. Studies have shown that ozone can increase the storage period of food, drink and fruits by 3 to 10 times.

Deodorize, deodorize. Ozone generator nature cause bad smell and corruption mainly of ammonia, hydrogen sulfide and methyl mercaptan, dimethyl sulfide and dimethyl disulfide, ozone can react with them the oxidation decomposition for non-toxic, odourless, so as to achieve the effect of deodorization.

Design of ozone generator

The risk may be caused by improper use, poor maintenance, and material replacement. The dangerous sources of ozone generators are oxygen, ozone, mechanical lines, electricity and air pressure, where oxygen and ozone are dangerous. But when ozone is used as the raw material gas, because it has the characteristics of combustion and accelerate combustion (especially when the volume content > 25%) in the air, so if ventilation is not good, equipment internal or external pipeline leak, or open the oxygen system can make oxygen concentration rise to dangerous levels. Increased oxygen concentration increases the risk of fire. For this reason, it is forbidden to use oil cloth and not contact with oil and butter.

Ozone is a poisonous and corrosive gas that can aggravate combustion, heavier than air and oxygen (which can be collected in the ground and narrow strips) and is spicy and unstable. Below are the human responses to the concentration of ozone. The use of ozone generator at home is not strictly required, but should be kept in a closed room when disinfected. After disinfection, it is best to wait an hour before entering, and open door window ventilated. The higher the humidity of the air sterilization effect, the better, but there is no air supply general household ozone machine processing equipment, the high humidity will affect the output of ozone machine, if the humidity is lower than 40% 50% could be greatly reduced ozone sterilization effect. Ozone generator ozone concentration is ok in half an hour more than 2.5 PPM boot ozone is a kind of earth's atmospheric trace gases, it is because the oxygen in the atmosphere by the sun radiation is decomposed into oxygen, oxygen atoms and with the surrounding oxygen molecules to form, containing three oxygen atoms. More than 90 percent of the ozone in the atmosphere is in the upper or stratosphere of the atmosphere, 10 to 50 kilometers above the ground, which is the ozone layer that needs human protection. A small number of ozone molecules still hover near the ground, and can still play a role in blocking ultraviolet light.

Choice must be noticed when ozone generator, ozone generator tube joint is flame retardant material, normal should be 4 b fluorine, some manufacturer use common plastic, life is short, also easily breakdown. Bad check cooling, cooling degree, ozone concentration on one or two hours is greatly reduced, particularly small ozone generator ozone generating tube of the same volume of the 3 grams of ozone, the greater the indicated that the manufacturer of advanced technology, thus the cost is low, the price is affordable. 4 people buy ozone machine is mostly water sterilization, the choice of the aeration is very important, some people think there's a machine that actually issued cannot fully dissolved ozone, ozone are wasted and isomers of oxygen, as strong oxidant; It reduces the pesticide, removes the bacterium effect is 1.5 times the chlorine gas, and its sterilization rate is 600 to 3,000 times faster than chlorine gas. Ozone is naturally decayed at room temperature for 15 minutes to 25 minutes. Ozone is rapidly converted into "ecological oxygen" in water, and there is no residual problem. Ozone is an efficient and rapid disinfectant. It can quickly neutralize pesticide residues in a short period of time, causing bacteria and viruses to be eliminated quickly. The air purity level requirement of the sterile drug production environment: what kind of purification process should we choose in order to meet the above requirements? There are four methods of sterilization. Ozone sterilization is one of the important methods. But no matter what disinfectant method, must achieve afore-mentioned regulation, ozone kill bacterium also be no exception. Ozone as a means of disinfection of traditional disinfection methods, people are stricter and easier to do, otherwise it is difficult to establish a foothold.

The ozone generator design conditions are as follows:

1) temperature: ozone generator ozone generator design environment temperature range of 0-40 ℃

Humidity: ozone generator design relative humidity < 90%

3) cooling water: use water cooling of the ozone generator design cooling water temperature 30 ℃ or less and can generally be used as ozone generator cooling water circulating cooling water plant

4) atmospheric pressure: the ozone generator is designed by the standard atmospheric pressure, which is 101.3 KPa

5) air condition: ozone generator using air dew point - 45 ℃ or less.

6) power condition: for standard ozone generator, 220V / 1ph / 50Hz power supply, or 380V / 3ph / 50Hz power supply.

The choice of ozone generator gas source

Ozone generator is chosen: the application of ozone is determined by the amount of the gas, which is divided into two types: disinfection and disinfection in the gaseous phase. Ozone generates and use in accordance with the generally rated number multiplied by the number of time to determine, but vuv6fdi accrued in different USES and different places the attenuation, and then determine. Ozone generator in use, air source configuration directly affect the occurrence of ozone concentration, yield and purity, air generally can be divided into ordinary air, dry air source, rich oxygen source and four industrial oxygen gas source, gas source configuration above, in the event of a same device, the concentration and the yield increasing in turn. According to the application common sense, general gas source should not be configured normally, because it will affect the connection service life of the device and cause the amount of instability. Therefore, the commonly used gas sources can be divided into the following types:

1) dry gas source - disinfection of space, water treatment, swimming pool water, aquaculture, circulating water, water recycling, etc

2) rich sources of oxygen, such as pure water, mineral water, sewage treatment, medical food workshop, etc

3) industrial oxygen sources - high purity requirements, important concentration requirements, and small air mass applications

3. Used for disinfection of application of the large space, such as medicine, food and other industries workshop sterilization, the general should be installed special line points to the workshop, make ozone distribution even, also some bubbled into the central air-conditioning duct line, but this way sometimes cause air conditioning duct corrosion of metal parts and ozone depletion.

4. Used for water treatment, the main configuration of ozone in water dosing device, generally divided into aeration type (direct aeration or oxidation tower), venturi jet type, negative suction or nicolas flamel, pump turbine hybrid style, such as more than its soluble in water can, in turn, improve efficiency, nicole, pump efficiency can reach above 95%.

1) aeration: tap water, water production, circulating water, sewage, industrial wastewater, etc

Venturi fluid: secondary water supply, pure water, mineral water, aquiculture, swimming pool water, etc

3) negative absorption: small water application

4) pump type: water application or ozone disinfectant application
