An air disinfection and purification system

Abstract

The invention discloses an air disinfecting and purifying system. The system comprises a purifying box body, the purifying box body is internally provided with a fresh air ventilating device used forintroducing outdoor air and a combined disinfecting and purifying device used for purifying indoor air. The fresh air ventilating device comprises an indoor air inlet which is used for feeding the indoor air into the purifying box body, an indoor air outlet which is used for exhausting clean air from the purifying box body to the indoor, an outdoor air inlet pipe which is used for introducing fresh air from the outdoor, an outdoor air outlet pipe which is used for exhausting indoor dirty air to the outdoor, and a multi-loop circulating air duct which is arranged in the purifying box body; thecombined disinfecting and purifying device is arranged between the indoor air inlet and the indoor air outlet, and integrates ultraviolet irradiation and negative ion technology; the function of efficient disinfecting and purifying of air in a hospital room can be achieved, the effect of purifying the indoor air can be achieved through introducing the fresh air into the room, quality of the air inthe hospital room is guaranteed, and a comfortable and easy rehabilitation place is created for patients.

Description

technical field [0001] The invention relates to the technical field of air purification in hospital wards, in particular to an air disinfection and purification system. Background technique [0002] Purifying the air in the hospital environment is an important measure to reduce the infection rate in the hospital. Hospitals are different from other public places. When patients are admitted to the hospital, they will bring in different bacteria and viruses, so that the air in the hospital is often polluted; patients and medical staff Patients are often exposed to pathogenic microorganisms; patients generally have low resistance to infection; and some medical staff may also pose a serious threat to the host's defenses. Pathogenic microorganisms can also infect patients. Factors that determine the infection process include: pathogenic microorganisms, the local environment of infection, and the systemic response of the host defense mechanism to infection. Purification of the ambi...

Problems solved by technology

[0003] The pollution of the large environment in the hospital has attracted people's great attention, and the air pollution in the small environment is not optimistic, such as different departments, inpatient wards, operating rooms, etc. in the hospital. Ultraviolet radiation and disinfectant spraying, fumigation, ozone, chemical and other methods, just as the application number 201710039685.4 is an invention of an air purifier, which uses ethanol organic solvents, acids, and alkalis to chemically react with pollutants in the air , completely eliminate the hazards of pollutants, and at the same time, the dust in the air can be greatly reduced by repeated water washing and liquid washing. These methods have certain limitations in the process of use:

[0004] (1) Long-term ultraviolet radiation can cause skin cancer, ultraviolet ophthalmia and ozone poisoning, etc. When disinfection is carried out in the inpatient room of a general hospital, in order to avoid ultraviolet radiation, the patient has to leave, which brings trouble to the patient. Especially for some patients with limited mobility and critically ill bedridden patients, it will undoubtedly bring greater pain and torture to the patients. Moreover, only by ultraviolet irradiation to achieve air purification, although it can achieve the effect of sterilization and deodorization, it is harmful to organic The removal ability of dirt, dust, etc. is poor, and secondary pollutants will be produced in the process of purifying the air; the manpower labor burden required by the method of spraying disinfectant or fumigation is heavy, and the efficiency of purifying air is low; although the ozone method can Purify the air, but it will also make the ozone content in the air in the hospital room higher, which will cause secondary damage to the health of the patient; chemical air purification requires a large amount of reactive reagents, which will increase the cost of air purification, thus Indirectly bring a heavier treatment burden to patients and increase hospitalization costs

[0005] (2) The function of the existing air purifier is relatively single, and there is often only one working mode for people to choose, that is, to achieve the purpose of purifying the air by sterilizing and disinfecting the indoor air. Sometimes, when the external conditions permit, only Through the exchange of indoor and outdoor air, the air purification effect can be realized. Therefore, the existing air purifier often makes the air purification operation process complicated, and the cost is also greatly increased.
