The utility model has the beneficial effects that the utility model passes through setting Multistage filtering device, so that foul smell is clean in entrance
Pass through multistage filtering before gas chamber, removes the larger particles in air first, then successively remove lesser particulate matter, improve sky
The effect of gas purification；Multistage filtering device passes through layering, it is ensured that the filter in internal layer keeps enough for a long time
Cleaning, guarantees the filter quality of Multistage filtering device, extends the service life of Multistage filtering device.
Detailed description of the invention
The present invention will be further described with embodiment with reference to the accompanying drawing.
Fig. 1 is the overall schematic of embodiment；
Fig. 2 is the schematic diagram of internal structure of embodiment.
Specific embodiment
Modified positive pressure as depicted in figs. 1 and 2 removes haze one-way flow fresh air host, including box body 1, wind with accommodating chamber
Machine 2 and Multistage filtering device；
One end of box body 1 is equipped with air intake passage 11, and the other end is equipped with air-out passage 12, and Multistage filtering device is located at accommodating chamber
Interior, accommodating chamber is divided into clean gas chamber 13 and foul smell room 14 by Multistage filtering device, and foul smell room 14 is connected with air intake passage 11；
Blower 2 is located at 13 in clean gas chamber, and the air inlet of blower 2 is connected with clean gas chamber 13, the air outlet of blower 2 and outlet air
Channel 12 is connected.
When modified positive pressure removes haze one-way flow fresh air host work, under the action of blower 2, outdoor air is passed sequentially through
Entering clean gas chamber 13 after air intake passage 11, Multistage filtering device filtering, filtered air is sent into air-out passage 12 by blower,
Eventually enter into interior.
The side that Multistage filtering device corresponds to box body 1 is equipped with maintenance door 3 for replacing Multistage filtering device, maintenance door 3
One end and box body 1 it is hinged, the other end and the retractable connection of box body 1.When needing replacing Multistage filtering device, inspection is opened
It repairs door 3 and more renews Multistage filtering device.
Multistage filtering device includes being sequentially connected logical primary filter 41, active carbon from foul smell room 14 towards clean gas chamber 13
Filter 42 and high efficiency particulate air filter 43.The filtration grade of primary filter 41 is G4, for filtering 5 μm with dust particles.It is high
The filtration grade for imitating filter 43 is G13, is used for 0.5 μm of particle dust below and various suspended matters.41 He of primary filter
High efficiency particulate air filter 43 is plank frame, and active carbon filter 42 is arranged between primary filter 41 and high efficiency particulate air filter 43 and uses
