Pipeless fresh-air washing air purification system

Abstract

The invention relates to a pipeless fresh-air washing air purification system which is composed of a silent fresh-air washing air purifier and expiratory valves mounted on the outer walls of rooms. Outdoor air is subjected to washing purification and pressurizing and then fed into the rooms, meanwhile, indoor air of the equal volume is pushed out of the rooms through the expiratory valves and doorand window cracks. The silent fresh-air washing air purifier comprises a control panel, an electric cabinet, a sensor group, a low-efficiency filter, a bag medium-efficiency filter, a high-efficiencyfilter, an ultra-silence fan, a water tank, a washing water pump, a washer and the like. Through pressurizing of the fan, the indoor air forms micro positive pressure, the indoor air flows unidirectionally, accordingly, unpurified outdoor air is prevented from entering the rooms through the expiratory valves or the door and window cracks, the indoor air can be continuously kept up to the superiorquality standard, distribution of fresh air of the multiple rooms is controlled by the expiratory valves of the rooms, and fresh air distribution is achieved without needing an indoor pipe. The fresh-air washing air purification system is suitable for being used in habitable rooms and small public places.

Description

technical field [0001] The invention belongs to the air purification technology, and in particular relates to a ductless fresh air washing air purification system. Background technique [0002] In the past 30 years, the smoking rate among the public in my country has been declining, but the prevalence of lung cancer has increased by more than four times, which has something to do with the increase in smog weather. Haze weather has an impact on human health, and sometimes foggy and cloudy weather also has the same problem. [0003] The composition of haze is very complex, including hundreds of atmospheric chemical particulate matter. Among them, aerosol particles with a diameter of less than 10 microns are mainly harmful to health, such as mineral particles, sea salt, sulfate, nitrate, organic aerosol particles, fuel and vehicle exhaust, etc., which can directly enter and adhere to the human respiratory tract and alveoli middle. In particular, submicron particles will be d...

Problems solved by technology

[0012] In order to overcome the problem of poor air purification effect in the prior art, the purpose of the present invention is to provide an air purification system that can comprehensively and effectively improve indoor air quality and meet GB / T18883-2002 "Indoor Air Quality Standard", that is, to provide a Ductless fresh air washing air purification system, the system not only intercepts pollutants in the fresh air, but also intercepts the unpurified air entering the room through the gaps in doors and windows, keeping the indoor air always up to the air quality standard, and can be used for multiple Distributing fresh air in each room, with the characteristics of low noise, fully automatic and easy operation
