Description

An energy-saving indoor purification system

technical field

The utility model relates to air purification equipment, in particular to an energy-saving indoor purification system.

Background technique

Air pollutants generally refer to foreign substances that enter the near-surface or lower atmospheric environment in gaseous form. Such as nitrogen oxides, sulfur oxides, and carbon oxides, as well as floating dust, suspended particles, etc., and sometimes formaldehyde, radon, and various organic solvents, which have adverse effects on the human body or the ecosystem. Air pollutants mainly include: carbon monoxide (CO), nitrogen oxides (NOx), sulfur oxides and particulate matter (PM).

In recent years, smoggy weather has become a very active keyword in the media. my country is a country with serious PM2.5 pollution. The overall situation is high PM2.5 pollution, especially in coastal areas. Moreover, with the continuous development of the economy and the rapid increase of urban car ownership, the proportion of small particulate matter in the urban atmosphere continues to increase. More attention should be paid to the harm of PM2.5 to human health. However, the vast majority of people spend 70% to 90% of their time indoors. The survey of the CCTV international website also shows that nearly 1/5 of people stay in a centralized air-conditioned environment for more than 8 hours a day. Therefore, the U.S. Centers for Disease Control and Prevention believes that indoor air pollution is more harmful to the human body than outdoor air pollution. Experts point out that indoor air particle pollution accounts for 76% of the entire indoor air pollution, and developing countries are more serious than developed countries. Therefore, it is more important to control the impact of indoor particulate matter pollution on human health.

The traditional central air-conditioning system controls the concentration of indoor particulate matter by setting air filters, but in fact, the concentration of outdoor particulate matter is constantly changing, especially in some special haze weather, the concentration of outdoor particulate matter is more than ten times that of normal conditions, so in During this period, if the traditional air conditioning filter system is still used, the particulate matter in the outdoor fresh air cannot be effectively filtered; if a filter with high efficiency is used in the design of the centralized air conditioning system, it will cause excessive resistance and high operating costs. It can be seen that the traditional centralized air-conditioning filter system has the disadvantage of not being able to meet the requirements of indoor particulate matter control in haze weather. In addition, due to the high content of particulate matter in the air, a large amount of particulate matter will be adsorbed on the filter during the filter adsorption process, resulting in a decrease in the filtering effect of the filter.

In order to solve the above technical problems, the Chinese utility model patent with the publication number CN204214060U discloses an indoor air purification system, which includes a fresh air duct, a filter section and an air outlet duct, and a filter device is arranged in the filter section. There is a sealed box between the air duct and the filter section, the sealed box is filled with filtrate, one end of the new air duct extends to the bottom of the sealed box, and the bottom of the sealed box is also equipped with an atomization block, and the sealed box It is connected to one end of the filter section through a pipeline, and the other end of the filter section is provided with an air outlet pipe. Filter the particulate matter in the air by filtering the liquid, and atomize part of the filtrate through the atomization block at the bottom of the sealed box, so as to perform secondary filtration on the particulate matter in the air. However, the indoor air purification system cannot utilize the return air, thereby causing waste of resources, which is not conducive to energy saving and environmental protection.
