In one embodiment, referring to fig. 4 and 5, the inflation pressurization system 300 includes an airtight chamber 310 and a fan assembly 320. Specifically, in connection with fig. 1, the air-tight chamber 310 is one or more small rooms in the annular room 103 of the building foundation 100. The airtight chamber 310 is provided with a first air supply port 311, a second air supply port 312, and a vent 313. The first air supply port 311 communicates with the airtight chamber 310 and the first space 110, and the second air supply port 312 communicates with the airtight chamber 310 and the second space 120. The fan set 320 supplies air to the airtight chamber 310 through the vent 313.
In one embodiment, the fan assembly 320 includes a housing 321, an air purification assembly 322, and a fan body 323. Housing 321 has a cavity 3211, and a fan body 323 is disposed within cavity 3211, and an air cleaning assembly 322 is configured to clean air passing through fan assembly 320. The casing 321 has an air inlet 3212 and an air outlet 3123 on both sides in the direction of illustration, and the air outlet 3123 communicates with the air vent 313.
In one embodiment, the air purification assembly 322 includes a first filter layer 3221 and a second filter layer 3222. Wherein, the first filtering layer 3221 is used for filtering large-sized impurities such as leaves, sundries and the like, which can cause damage to the fan body 323, the second filtering layer 3222 is used for purifying air, namely, the second filtering layer 3222 is used for filtering small particles suspended by dust and the like in the air, so that the air entering the first space 110 is clean enough. That is, air passes through the first filter layer 3221 and the second filter layer 3222 in order as it enters the first space 110 from the outside.
In one embodiment, the first filter layer 3221 is a barrier mesh, preferably a metal mesh, and the first filter layer 3221 is disposed at the air inlet 3212. The second filter layer 3222 is a primary filter screen for filtering dust with a particle size of 5 μm or more, and has a filtration efficiency of about 90%. Solid and liquid particles float in air and have a particle size of about 0.1 microns to about 100 microns, and particles with a particle size of 10 microns are generally counted to be deposited in the upper respiratory tract, enter the deep respiratory tract with a particle size of 5 microns, and enter the bronchi and alveoli with a particle size of less than 2 microns. The second filter layer 3222 in this embodiment can filter particles having a particle size of 5 micrometers and above. It is possible to ensure that the air introduced into the first space 110 is clean.
In one embodiment, the air cleaning assembly 322 further includes a third filter layer 3223, wherein the third filter layer 3223 is a medium-efficiency filter or a high-efficiency filter for filtering respirable particulate matters with a particle size of 0.5 μm or more, and the filtering efficiency is about 90%. For example, when air enters the first space 110, it passes through the first filter layer 3221, the second filter layer 3222, and the third filter layer 3223 in order, further, in order to prevent the air from being polluted again by the blower body 323 after being purified, the blower body 323 is disposed between the first filter layer 3221 and the second filter layer 3222. Of course, in other embodiments, the fan body 323 may be disposed between the second filter layer 3222 and the third filter layer 3223, or between the third filter layer 3223 and the air inlet 3212, so that the air contacts the fan body 323 after being purified, thereby reducing dust adhering to the fan body 323, and keeping the fan body 323 clean for a long time.
Preferably, the fan body 323 is disposed between the second filter layer 3222 and the third filter layer 3223, so that not only can the outside dust be prevented from polluting the fan, but also the air inside the air film building can be prevented from polluting the fan, thereby the fan body 323 does not need to carry out ash cleaning treatment, and the performance of the fan body 323 is kept for a long time.
In one embodiment, referring to fig. 4, the inflation pressurization system 300 further includes a one-way check valve 330, such as the one-way check valve 330 disposed within the air inlet 3212, by providing the one-way check valve 330 such that air can only enter the airtight chamber 310 from the outside and cannot flow in the reverse direction. In other embodiments, one-way check valve 330 may be disposed at other locations within housing 321.
In one embodiment, referring to fig. 4, a first air supply port 311 is provided at a side wall 101 of an airtight chamber 310 of a building foundation 100, a second air supply port 312 is provided at a top wall 102 of the airtight chamber 310 of the building foundation 100, and both the first air supply port 311 and the second air supply port 312 are provided with an air valve 340, the air valve 340 being capable of adjusting a flow rate of air so that the air blower unit 320 is capable of proportionally inflating the first space 110 and the second space 120. That is, the air pressure in the first space 110 and the second space 120 can be adjusted by the air valve 340. For example, the air pressure in the first space 110 is made greater than the air pressure in the second space 120 by more than 50Pa to ensure that the inner film 210 is completely arched, and the air pressure in the second space 120 is made greater than the external air pressure by more than 180Pa to ensure the overall supporting strength of the inner film 210 and the outer film 220. Before severe weather comes, for example, when the weather such as storm and the like is met, the air pressure in the second space 120 can be adjusted through the air valve 340, so that the air pressure in the second space 120 is more than 450Pa of the external air pressure, the air film building can still keep enough supporting strength in severe weather, the air film building can not shake along with the wind, and large deformation can not occur due to snow, and at the moment, the film can not be damaged due to the fact that the pressure inside the air film building is large due to the protection of the film reinforcing system 500. After the weather is normal, the air pressure in the second space 120 is adjusted to be more than 180Pa larger than the external air pressure, so that the electric energy consumption is saved on the premise of ensuring the safe support of the air film building.
