Description

Embedded semi-hidden indoor air supply air purifier

technical field

The utility model relates to the technical application field of the fresh air system, more specifically, it relates to a semi-concealed indoor air supply air purifier embedded in a wall or a window to isolate indoor and outdoor media.

Background technique

Since January 9, 2013, the central and eastern regions of the country have been caught in severe smog. At 10:00 on January 13, Beijing even issued the first orange haze warning in Beijing's meteorological history. In mid-January, Beijing's air pollution index was close to 1000. From northeast to northwest, from north to central China, and even the Huanghuai and Jiangnan regions, there have been severe and severe smog weather in a wide range. In January of this year, 4 times of smog covered 30 provinces (autonomous regions and municipalities). In Beijing, only 5 days were not smog days. According to a report, less than 1% of the 500 largest cities in China meet the air quality standards recommended by the World Health Organization.

Smog will have a great impact on people's daily life and travel, and will affect the human respiratory tract. Among them, the main hazards to health are fine particles and aerosol particles with a diameter of less than 10 microns, such as mineral particles, sea salt, sulfate, and nitric acid. Salt, organic aerosol particles, fuel and automobile exhaust, etc., can directly enter and adhere to the human respiratory tract and alveoli, especially particles with a diameter of less than 2.5 microns will deposit in the upper and lower respiratory tract and alveoli respectively, causing acute rhinitis And acute bronchitis and other diseases, if you stay in this environment for a long time, it will also induce lung cancer. Haze days also have a serious impact on human cardiovascular and cerebrovascular diseases, which will hinder normal blood circulation, lead to cardiovascular disease, hypertension, coronary heart disease, cerebral hemorrhage, and may induce angina pectoris, myocardial infarction, heart failure, etc., causing chronic bronchitis Pulmonary heart disease, etc. Normal people stay in smog for a long time, which can cause bronchitis, laryngitis, pneumonia, asthma, rhinitis, conjunctivitis and allergic diseases, and also have a certain impact on the growth and physical fitness of children and adolescents. In addition, haze days are more harmful to the health of the elderly and children with weaker resistance.

In haze weather, "PM2.5 fine particulate matter" is the "culprit". PM2.5 fine particulate matter refers to aerosol particles, bacteria and other fine particles with an aerodynamic diameter less than or equal to 2.5 microns in the ambient air. In order to remove PM2.5 fine particles in indoor air and purify indoor air, people use air purifiers or fresh air systems to remove indoor "PM2.5 fine particles".

The principle of the air purifier is to drive the indoor air to flow through the fixed filter membrane through the fan, and to purify the air that flows through the filter membrane to achieve the purpose of purifying the indoor air. It does not exchange with the outdoor air and purifies the internal circulation. Therefore, the use of air purifiers has two very serious defects. First of all, when using air purifiers indoors, the indoor airtightness is required, and the indoor air does not circulate with the outdoor air to achieve the purification effect. The carbon dioxide content in the environment increases and the oxygen content decreases, which will have adverse effects on human health. Secondly, if the windows are opened for ventilation in a closed environment for a long time, the haze air outside will enter the room, pollute the indoor air, and endanger human health.

The fresh air system is based on the principle of sending fresh air to the room with special equipment on one side of the closed room, and then exhausting it from the other side to the outside by special equipment. A "fresh air flow field" will be formed indoors to meet the needs of indoor fresh air ventilation. . The fresh air system consists of one or several fresh air hosts, a set of air supply duct system, and a set of exhaust duct system. The fresh air host is responsible for purifying the outdoor air and sending it into the room, and at the same time, the indoor dirty air with low oxygen content is discharged outside. ; The air supply duct system is responsible for sending purified fresh air into the room, and the exhaust duct system is responsible for discharging indoor dirty air outside. Because there is an air supply duct system and an exhaust duct system, the fresh air system is suitable for installation before the house decoration. After the decoration, the installation will not only require a large amount of installation work, but also affect the indoor aesthetics. The air supply duct system will become dirty after long-term use, and the purified fresh air will form secondary air pollution when passing through the air supply duct system. The fresh air main unit will occupy the indoor space and affect the aesthetics and usable space of the room.

Utility model content

The purpose of the utility model embedded in the semi-concealed indoor air supply air purifier is to purify the air that enters the indoor air quality index (AQI) that does not meet the standard, and remove particulate matter, "PM2.5 fine particle matter" and some bacteria in the air. The object becomes clean air, so that the indoor air quality index (AQI) reaches the standard of excellent index; another purpose of the utility model has the function of replacing the indoor air with the outdoor air, so as to ensure the indoor air circulation and effectively suppress the air pollution. The content of carbon dioxide in the water and ensure sufficient oxygen content.

In order to achieve the above-mentioned purpose, the technical means adopted by the utility model to embed the semi-concealed indoor air supply air purifier is to install and embed the semi-concealed indoor air supply air purifier indoors, which is installed in the medium separating the indoor and outdoor environments. , which can be a wall or a window.
