How to disinfect the air? The best way to disinfect the air

If there is also a lot of endotoxin accumulation in the gas, it may cause a variety of damage to the body, so it is necessary to find a suitable disinfectant to prevent damage to the human body. The following detailed introduction is what disinfectant is used for gas disinfection, I hope that everyone can master some basic types of disinfectants, and also attach great importance to the key methods of influenza disinfection, and choose the appropriate disinfection method for different virus types, the efficiency will be much higher.

What disinfectant is used for gas disinfection.

When indoor disinfection, active oxygen disinfectants, 84 disinfectants, and photocatalyst formaldehyde removal disinfectants can be considered.

1. Active oxygen disinfectant.

Ozone sterilization is a bacteriolytic grade method, complete sterilization, residue, broad-spectrum sterilization, can destroy bacterial propagules and spores, viral infections, bacteria, etc., and can destroy meat endotoxin. In addition, it can quickly spread to all the sterilization room space, and there is no dead angle for sterilization. It is a zero-pollution disinfection method.

Problem: Bromate is caused when reactive oxygen air oxidizes source water with bromine ions. Bromate has been classified as a Class 2b potential carcinogen by the International Organization for Scientific Research on Cancer, which may cause damage to the physical and mental health of the body.

Disinfectant. Calcium hydroxide is a key ingredient in disinfectants with an available chlorine content that destroys Vibrio parahaemolyticus, pyogenic gram-negative bacilli and bacterial spores. It is suitable for disinfection and sterilization of the surface of general blocks, milky white clothes, and environmental pollutants in hospital outpatient clinics.

Advantages: **Low, long-term disinfection and sterilization. Defects:

Strong corrosion, very easy to cause damage. Contains carcinogens.

3. Photocatalyst formaldehyde removal disinfectant.

Photocatalyst formaldehyde removal is a kind of hydroxide raw material of silicon oxide (titanium dioxide is more common), which is applied to the surface of the plate, and under the effect of the light source, it causes obvious catalytic reaction dissolution: it can reasonably dissolve harmful substances in the air; It can reasonably destroy a variety of germs, and can dissolve and harmless the endotoxins released by germs or bacteria; In addition, it also has the functions of deodorization and stain resistance. Features:

It has a wide range of applications, such as sterilization and odor removal, and indoor air purification. Defects: It needs to be under a light source to be fully utilized.

A key way to disinfect the flu.

1. Patient protection, disinfection and sterilization: If many people in the family have a cold and fever, it is best to protect it in a room, and put a flat dish of vinegar in the house, and the usual vinegar can be sterilized! For other rooms, you can also put vinegar!

Be careful to put it on a straight plate, so that it will release more quickly and the concentration of vinegar will be larger.

2. Open the window door for disinfection and sterilization: In winter, the windows and doors of every household are closed, and the air conditioning and radiators are turned on inside, and after a long time, the gas is becoming more and more turbid, and the average temperature is high, and the virus infection is becoming more and more rampant. If you are really afraid of cold, you should at least ventilate indoors in the morning, noon and evening.

The above analysis is what disinfectant is used for gas disinfection, and in the whole process of removing the accumulation of viral infection, it is necessary to find some appropriate ways to select a suitable elimination plan, including ethanol or ultraviolet light. In addition, calcium hydroxide disinfectants can also be used. All in all, to consider.

1. Vinegar disinfection method Vinegar contains acetic acid and other components, which has a certain sterilization ability and is often used for indoor air disinfection. For a room of about 10 square meters, you can use 100 150 grams of vinegar, add 2 times of water, put it in a porcelain bowl and simmer slowly, and close the doors and windows when fumigating.

2. Spray disinfection uses mechanical or chemical aerosols to spray 84 disinfectant in the air, and relies on aerosols suspended in the air to purify or disinfect the air. With a flow rate of up to 300ml per minute and a spray distance of up to 8m, it is easy to operate and can spray and disinfect objects and fabric surfaces at various angles.

3. Ultraviolet lamp disinfection is divided into fixed irradiation and mobile irradiation. According to the configuration, the installation height is about to be from the ground, and the irradiation time needs 60 120min, which has a good disinfection effect.

4. Ozone generator disinfection is divided into miniature, that is, the ozone generation is low, which is used for sanitation and cleaning, or disinfection of small spaces; Large, even if the ozone generation is large, is used for indoor air disinfection. Under the condition of 70% relative humidity, ozone concentration is 4 6mg m, and the working time is 60min, which can meet the disinfection requirements. Ozone has a corrosive effect on metals, has an accelerated aging effect on rubber and plastics, and has a certain toxicity to people.

Spray disinfection method: vinegar contains acetic acid and other components, which has a certain sterilization ability and can be used for indoor air disinfection. Mix one part of vinegar with one part of water, put it into a sprayer, and spray and disinfect it after closing the doors and windows before resting at night, spraying 5 10 ml of raw vinegar per cubic meter of space in the building, disinfecting once every other day, a total of 3 sprays.

If there is already a sick person in the family, the amount of vinegar should be increased to 150 250 ml per room.

Fumigation and disinfection method: close the doors and windows, pour the vinegar into the iron pot or casserole and other containers, add water 2 times, boil with a simmer, so that the acetic acid vapor fills the room, until the vinegar is boiled dry, add a little water after the container cools, dissolve the remaining vinegar at the bottom of the pot, and then fumigate, and so on 3 times. The dosage of vinegar is 100 150 ml per house for 5 days.

Artemisia leaf fumigation method: Artemisia artemisia is also known as mugwort, which contains volatile oil, the main ingredient of eucalyptus, which has antibacterial effect on anthracnose, hemolytic streptococcus, diphtheria bacillus, pneumococcus, Staphylococcus aureus, Bacillus subtilis, etc. Calculate the amount of mugwort leaves required by 1 gram of dried mugwort leaves per cubic meter, put them in an iron container and ignite them until the mugwort leaves are burned to ashes.

Air purifier method: The above three disinfection methods only last for a few hours for air disinfection, and often return to the pre-disinfection level after 3 to 4 hours. Ultraviolet air sterilization and disinfection are now used, but this disinfection method has a certain amount of radiation and poses a potential threat to human health.

The air purifier using the "plasmacluster" technology can achieve air disinfection while ensuring the safety of life.

Does it mean air disinfection in home decoration? The main thing is ventilation. If it's like the new coronavirus, you definitely have to spray disinfectant on the environment.

First of all, open the windows frequently for ventilation and air circulation, which can purify and disinfect the air; secondly, vinegar can be poured into a container, and then put into an electric furnace or coal stove to heat, and vaporization can be used to disinfect the air; Finally, ultraviolet lamps are installed indoors, and every 1 hour of use can achieve the effect of killing viruses.

The best way to disinfect the air, experts tell you, is ventilation.

The best way to disinfect the air is to release oxygen from nature's large forests, so that the oxygen released can disinfect those carbon dioxide.

Hello, I see that you are very interested in the topic of air disinfection, I am an expert in this area, and I am happy to answer your questions. Air disinfection is a very important task, especially in the current high incidence of influenza, which is very critical to reduce the spread of the virus. So how do you disinfect the air?

First of all, there are many ways to disinfect, but the most commonly used are ultraviolet disinfection and ozone disinfection. Ultraviolet disinfection refers to the use of ultraviolet sterilization, which is suitable for bacteria, viruses, molds, etc. in the air, while ozone disinfection refers to the use of ozone gas for sterilization, which is suitable for odor, formaldehyde and other harmful substances in the air. In addition, there are methods such as ion disinfection and photocatalyst disinfection, but these methods are slightly less effective than the first two disinfection methods.

Secondly, when disinfecting the air, it is necessary to consider the size of the disinfection area, as well as the use of the disinfection machine, etc. For small spaces, a small UV germicidal lamp or ozone sterilizer can be used for disinfection, while for large spaces, multiple disinfection machines need to be used together. In addition, it is necessary to pay attention to the duration and frequency of disinfection, generally speaking, one disinfection per day can achieve better results.

How air disinfection is carried out depends on the specific use scenario. If it is to be operated under the environmental conditions of manned operation, more physical methods are used; If it is possible to work unmanned, chemical methods can be considered.

Physical method: The air disinfection machine that uses electrostatic adsorption, filtration technology and ultraviolet rays to kill or remove microorganisms in the air to meet the disinfection requirements can be used for indoor air disinfection when there are people. Such as electrostatic adsorption air sterilizers, high-efficiency filters (HEPA), ultraviolet air sterilizers, etc.

Chemical method: The air disinfection machine that uses the chemical factors generated to kill the microorganisms in the air and meets the disinfection requirements is only used for the disinfection of indoor air when no one is there. Such as chlorine dioxide air disinfection machine, ozone air disinfection machine, hydrogen peroxide air disinfection machine, peracetic acid air disinfection machine, etc.

Physical disinfection method: A: Open windows for ventilation, which is the preferred method of air disinfection, safe and effective. b: Ultraviolet irradiation disinfection, irradiation for more than 30 minutes.

Chemical disinfection: peracetic acid fumigation and disinfection: the amount of peracetic acid fumigation and disinfection of indoor air and smooth surface is 1g m.

During fumigation, the peracetic acid stock solution is diluted with water into an aqueous solution of about 5, placed in an enamel basin (please note not to contact with metal), placed on an electric stove with asbestos nets, closed doors and windows, turned on the power supply, and cut off the power supply when the peracetic acid evaporates to tens of milliliters, and act for 30 60 minutes, and open the doors and windows.

1.Natural ventilation is the most economical, easy and effective way to keep indoor air fresh and reduce the concentration of bacteria. It can be used with or without people. It is of great significance to prevent the spread of SARS.

2.In the case of respiratory infectious diseases, a single air disinfection method can quickly pollute the air again because all the microorganisms in the air are killed, because the microorganisms on the contaminated surface are not killed. In this case, the more reasonable method should be to disinfect the surface of the object and disinfect the air at the same time, and spray or fumigation can be carried out with disinfectants such as peracetic acid or hydrogen peroxide.

3.The air disinfection method when people are in Minkai can choose to use a circulating air sterilizer or an air sterilizer such as electrostatic for continuous dynamic disinfection. When using this air disinfection method, it should be combined with the hygienic cleaning treatment of indoor surfaces or disinfectant to disinfect the contaminated surfaces first to ensure the air disinfection effect.

Air disinfection precautions.

1.For the corrosion of articles, peracetic acid, ozone and other disinfectants have different degrees of damage to the articles, the concentration should not be too high when using, the spray volume should not be too large, if necessary, should be scrubbed with water in time after disinfection.

2.When using disinfectants for air disinfection, it is best to use special aerosol air sterilizers, because the fog particles of the constant sprayer are large, and the disinfectant stays in the air for a short time, which is difficult to achieve the desired disinfection effect.

3.When using disinfectant for air disinfection, doors and windows should be closed, personnel should leave the disinfection place, and after the disinfection is completed, the doors and windows should be opened for ventilation, and the disinfectant should be removed before entering.

4.When exposed to ultraviolet light, it cannot be directly irradiated and exposed**, and the eyes cannot look directly at the ultraviolet lamp. so as not to cause damage to the ** and eyes.

5.Personal protection, when spraying with disinfectants such as peracetic acid, disinfection personnel should do personal protection, such as wearing masks, glasses, gloves, etc.
