Fresh air PM2.5 air purifier

Abstract

The invention discloses a fresh air PM2.5 air purifier. The fresh air PM2.5 air purifier comprises a shell, an air purification device and an openable door, wherein the air purification device is arranged in the shell; the shell is in a cuboid shape, an air inlet pipe connector is arranged on one side face of the shell, and an air outlet pipe connector is arranged on the other side face opposite to the air inlet pipe connector. The air purification device is of a plate type and comprises a primary-efficiency filter net, an electrostatic dust collector, a high-efficiency filter net, a composite ozone removal activated carbon net and a photochemical catalysis filter net which are sequentially arranged between the air inlet pipe connector and the air outlet pipe connector. A sterilization ultraviolet lamp is arranged between the activated carbon net and the photochemical catalysis filter net. A negative-ion generator is further arranged behind the photochemical catalysis filter net. The openable door is in hinge joint with the shell and is provided with a terminal board and a door control switch. The fresh air PM2.5 air purifier can remove PM2.5 and haze efficiently, kill various bacteria and fluid pathogens in air and increase negative oxygen ions in a room and has the functions of low air resistance, low energy consumption, no ozone and multiple power-off protection, and a filter layer does not need to be replaced frequently.

Description

technical field [0001] The invention relates to the field of air disinfection and purification, in particular to a fresh air PM2.5 air purifier used in a fresh air system. Background technique [0002] PM2.5 is also called fine particles, fine particles, and fine particles. PM2.5 refers to particulate matter in the ambient air with an aerodynamic equivalent diameter less than or equal to 2.5 microns. It can be suspended in the air for a long time, and the higher its concentration in the air, the more serious the air pollution. Although PM2.5 is only a small component of the earth's atmospheric composition, it has an important impact on air quality and visibility. Compared with coarser atmospheric particles, PM2.5 has small particle size, large area, strong activity, easy to attach toxic and harmful substances (such as heavy metals, microorganisms, etc.), and has a long residence time in the atmosphere and a long transportation distance. Therefore, it has a greater impact ...
