Description Book Molecular Air Disinfection Purifier Technical Field

The invention relates to an air sterilizer, in particular to a molecular air sterilizing and purifying machine.

Background technique

Human beings have resisted disease for their own health and have tried various methods. Sterilization is one of the methods. In order to kill various bacteria and viruses more effectively. Humans have found more than one hundred kinds of disinfectants. Chlorine dioxide is an environmentally-friendly disinfectant that has been widely used in the medical and health industry to kill viruses in recent years.

Chlorine dioxide is a yellow-green or yellow-brown gas with a pungent chlorine odor and is highly soluble in water without reacting with water. In 1977 American studies succeeded in the stabilization of chlorine dioxide solution. Chlorine dioxide is a highly effective and low-toxic disinfectant. It has a good killing effect on most bacteria, viruses, spores, fungi, etc., and it has a small amount, a fast effect, and a long lasting effect. Chlorine dioxide does not produce carcinogenic hydrocarbon compounds such as dichloromethane or trichloromethane (THMS). Therefore, most tap water plants in Europe and the United States use chlorine dioxide instead of chlorine for disinfection of tap water. Is being adopted by the World Health Organization due to a series of advantages of chlorine dioxide (cio ₂ )

(WHO) and the World Food and Agriculture Organization (FAO) recommend to the world an AI-grade high-efficiency safe disinfectant. This high-efficiency, broad-spectrum, safe, non-toxic, and non-residual disinfectant is widely used in Europe, America, Southeast Asia, and Japan. It can kill all microorganisms, including bacterial propagules, bacterial spores, fungi, mycobacteria, and viruses. The antibacterial effect of chlorine dioxide has been recognized as a promising result in the prevention of SARS in Shenzhen due to the large-scale use of chlorine dioxide spray disinfection. Chlorine dioxide, which is an air bactericide, is also widely used in the food industry to ensure the killing of more than 99.99% of various microorganisms in the air environment of production vehicles. The main killing characteristics of chlorine dioxide as a highly effective disinfectant have been proved by experiments:

(1) Efficient and powerful

Among the various commonly used disinfectants, the concentration required to achieve the same bactericidal rate of chlorine dioxide at the same time is the lowest. The effect of cio ₂ on the killing of E. coli in surface water is more than 5 times higher than that of α ₂ .

(2). Fast and lasting

After dissolving in water, chlorine dioxide does not chemically react with water, and its diffusion rate and permeability in water are faster than chlorine, especially at low concentrations. When the concentration of bacteria is 105 106 / ML, 0.5ppm of C10 ₂ can kill more than 99% of the bacteria under 5 minutes, and the killing rate remains unchanged for 12 hours, while the same amount of liquid chlorine (Cl) ₂ ) The maximum can only reach 75%. According to clinical studies conducted by Shanghai Second Medical University, Staphylococcus aureus in the air can be killed by using 250 mg/L of chlorine dioxide at a concentration of 2 ml/m ³ for 15 minutes. (3) Broad spectrum sterilization

Chlorine dioxide is a broad-spectrum disinfectant that has a good killing effect on all pathogenic microorganisms that are transmitted by air and water, and does not produce drug resistance, especially for typhoid, hepatitis A, hepatitis B, scleropathitis and AIDS. Viruses, etc. also have a good killing effect.

(4) Non-toxic and non-irritating

The acute oral toxicity test shows that the chlorine dioxide disinfectant is an actual non-toxic product. It will not cause damage to the oral mucosa, skin and hair. It is absolutely safe in acute toxicity and genetic toxicology. .

(5) Safety and function

Chlorine dioxide does not react with organic substances in the gas to form carcinogens such as trihalodecane. It is not carcinogenic, teratogenic, mutagenic to higher animal cells, sperm and chromosomes, and the amount of chlorine dioxide used is very low, so dioxide is used. Chlorine disinfection is safe, has no residual toxicity, and its safety is classified as AI by the World Health Organization (WHO).

Since bacteria, viruses, and fungi are single-celled organisms, the enzyme system is distributed on the surface of the cell membrane, and the chlorine dioxide molecules directly attack the enzymes on the surface of bacteria and virus cells, causing them to inactivate and cause rupture and death. Since the enzyme system of human and animal cells is protected by the organelles located inside the cells, the disinfecting concentration of chlorine dioxide molecules is safe for human and animal cells.

Chlorine Dioxide Sterilization Performance After long-term scientific and repeated demonstration by the US Food and Drug Administration (FDA) and the US Environmental Protection Agency (EPA), the effect of chlorine dioxide on drinking water was tested and confirmed as Sterilization and sterilization in medical and health processing, food processing (meat, aquatic products, fruits and vegetables), antiseptic, fresh-keeping, environment, drinking water, etc., sterilizing, disinfecting, deodorizing, imaginative agents, is internationally recognized chlorine disinfection The most ideal replacement product for the agent. Chlorine dioxide can rapidly oxidize sulfides (such as H ₂ S) to sulfate ions, remove the odor generated by organic sulfur, and oxidize and degrade CN -, N0 ² \ NH ³ into non-toxic C0 ₂ , N _{2 ,} etc. substance. It can be seen that chlorine dioxide not only has a good sterilization effect, but also has a multi-faceted function of anti-mildew, deodorization, etc., and can be widely used in public places, air, refrigerators, cold storages, offices, dormitories, cars and Air disinfection and deodorization of air conditioning ventilation systems can also be used for sterilization of patients' homes, wards and patient items.

Currently commonly used disinfection methods are spray disinfectant and ultraviolet light. UV lamp irradiation disinfection does not need to be operated manually after installation, it is convenient to use, does not need to disinfect the liquid, and the cost is low, but the ultraviolet light can not reach the place (such as behind the refusal in the family, under the cabinet, etc.) can not achieve the disinfection effect Therefore, it is easy to leave a dead corner that cannot be disinfected. The disinfection method of spraying the disinfectant is to spray the disinfectant liquid into the space to be disinfected by a sprayer, which can be disinfected anywhere, without leaving a dead angle that cannot be disinfected, but the sprayed liquid contains acid and alkali. Metal salt ions can cause corrosion to metal parts in electrical equipment.

Summary of the invention The technical problem to be solved by the invention is to provide a molecular air disinfection purifier which does not cause damage to articles in the disinfection space, does not leave a disinfection dead angle, is simple and convenient to use, and can meet the requirements of hygiene sterilization.

The design idea of the invention is to transfer the chlorine dioxide molecules from the aqueous phase to the gas phase, and then escape to the entire space to be disinfected for disinfection.

According to the disinfection routine, the chlorine dioxide molecules in the air need to reach a certain concentration to have a disinfecting effect. However, the concentration and time of chlorine dioxide molecules naturally escaping from the chlorine dioxide solution are difficult to control, and the specified disinfection concentration cannot be guaranteed. The natural escape will greatly reduce the disinfection effect, and it is difficult to ensure the disinfection effect. Therefore, the present invention adopts the following technical solutions:

A molecular air disinfection and purifying machine, comprising:

a casing having a cup-shaped container for containing a chlorine dioxide solution;

An air pump installed in the casing;

At least one aeration head mounted to the bottom of the cup-shaped container of the casing and communicating with the air outlet of the air pump through a one-way valve; and a timing device for controlling the working time of the air pump and the aeration head .

Further, a cup-type fan device may be disposed at the open end of the cup-shaped container for accelerating the escape of vaporized chlorine dioxide molecules in the cup-shaped container to the space to be disinfected, so that the molecular state air disinfection and purifying machine Large spaces such as homes, wards, and workshops can be disinfected.

The cup-shaped container may be made of a transparent material and provided with a scale on the wall of the cup for measuring the volume of the contents so as to measure the amount of the disinfectant used by the user.

When the disinfecting and purifying machine is in operation, the air pump generates compressed air and sends it to the aeration head, and the aeration head aerates, so that the chlorine dioxide molecules in the chlorine dioxide solution in the cup-shaped container rapidly change from the water phase state to the gas phase state, and quickly escape. Disperse into the entire sealed space to be disinfected, so that the sterilization concentration is reached within the specified time (5-15 minutes) and the required sealed disinfection time is continued. Due to the rapid and non-porous diffusion of chlorine dioxide molecules, a highly effective air disinfection effect is achieved. According to the size of the space to be disinfected, the concentration of the chlorine dioxide solution and the amount of the solution can be adjusted to meet the hygiene sterilization requirements.

Compared with the prior art, the molecular state air disinfection purifier has the following advantages:

It sterilizes the chlorine dioxide molecules in the chlorine dioxide solution from the aqueous phase to the gas phase. Therefore, it only liberates the chlorine dioxide molecules into the air, and other acid forms in the solution. Most of the basic metal salt ions remain in the solution and do not come into contact with the contents of the sterilization space, so they do not cause damage to the contents of the sterilization space.

Under the action of the fan device, the chlorine dioxide molecules that escape into the air accelerate the escape and fill the space to be disinfected without leaving a disinfection dead angle.

Because it can quickly disperse the chlorine dioxide molecules in the chlorine dioxide solution to the space to be disinfected and reach the specified disinfection concentration, it can fully meet the hygiene sterilization requirements. In addition, when the air disinfection purifier is in use, it is only necessary to put a prescribed amount of chlorine dioxide solution into the cup-shaped container according to the size of the space to be disinfected, and set the disinfection time, and the disinfection is automatically performed when the power is turned on, which is simple and convenient to use. And low cost, it is the most economical and most suitable disinfection and purification equipment for preventing airborne diseases such as SARS, influenza, avian influenza, tuberculosis, and ward operating room disinfection. It can be widely used in household, hospital, office, and workshop. It can also be used for disinfection of trains, airplanes, cars and other vehicles.
