In order to solve the problems of the existing technology, such as Figure 1 to Figure 5 As shown, the present application provides a boost purification system, including a first boost purification device 100, the first boost purification device 100 includes a first outer wall 101, the first outer wall 101 has a first end 110 and a second end 120 along a first direction X; the structure of the first outer wall 101 can be a hollow structure of any shape, such as a hollow square column or cylindrical structure, the first end 110 of the first outer wall 101 serves as an air inlet end, and the second end 120 serves as an air outlet end.

[0032] A first filter 102 is disposed inside the first outer wall 101, and a first cavity 130 is defined between the first filter 102 and the first outer wall 101. The cylindrical wall of the first filter 102 forms a second cavity 140. In some embodiments, the first filter 102 may select different filter element structures according to actual needs, such as selecting a MERV16 standard filter element for general dust protection, a HEPA standard filter element for high-standard dust protection, and an activated carbon filter element for toxic gas protection.

[0033] A first air supply device 103 is provided near the first end 110. In some embodiments, the first air supply device 103 is a booster fan, such as a 24V / 12V high-performance fan. In specific applications, the positive pressure range in the operating room is referred to the ISO23875 standard and the carbon dioxide concentration data is combined to match the corresponding fan to determine the fan model. Specifically, in actual applications, the resistance of the air inlet duct must also be considered, and the air intake volume and air pressure of the fan must have a certain redundancy.

[0034] In order to fix the first filter 102 and the remaining structures, the present application provides a first fixing portion 104 inside the first outer wall 101 near the first end 110. Specifically, the first fixing portion 104 is provided between the first air supply device 103 and the first filter 102. In some embodiments, the first fixing portion 104 is a fixing plate provided inside the first outer wall 101, and the diameter of the fixing plate may be the same as the diameter of the filter element. The first air supply device 103 may be fixed on the first fixing portion 104.

[0035] The first swirl blade 105 is arranged on the periphery of the first fixed part 104, and the first swirl blade 105 is arranged at intervals along the circumferential direction. In other specific applications, the first swirl blade 105 is arranged at the rear end of the first air supply device 103, and in other specific applications, the first swirl blade 105 is arranged around the filter element inlet. As a preferred structure, the first swirl blade 105 has an inclination angle θ along the first direction X, satisfying: 30°≤θ≤60°, such as the first swirl blade 105 has an inclination of 45 degrees along the first direction X. The combination of the first air supply device 103 and the first swirl blade 105 in the first boost purification device of the present application ensures that the wind blown out by the first air supply device 103 rotates when passing through the first swirl blade 105 and the rotation speed reaches the maximum, so that the dust in the airflow can generate the maximum centrifugal force, so that the particles in the air rotate against the cylinder wall of the first outer wall 101.

[0036] The first boost purification device 100 of the present application is provided with a first air outlet 106 near the second end 120. The first air outlet 106 is the air outlet of the first filter 102. The first air supply device 103 rotates at high speed. The external air is sent into the first cavity 130 through the first swirl blade 105 to generate high-speed rotation. The incoming air in the first cavity 130 is filtered by the first filter 102 and then enters the second cavity 140. The incoming air entering the second cavity 140 is sent out through the air outlet.

[0037] In order to better achieve the purpose of the present application, the first boost purification device 100 of the present application is provided with a dust outlet 107 on the first outer wall 101, and the dust outlet 107 is arranged near the second end 120. In some specific embodiments, the first outer wall 101 is provided with two dust catching grooves 109 near the second end 120, and the outlet end of each dust catching groove 109 is provided with a dust outlet 107. The dust catching groove 109 is located between the outer wall of the first filter 102 and the first outer wall 101, and can capture dust when the dust-laden airflow reaches the end. In some embodiments, the dust catching groove 109 is arranged along the inside of the first outer wall 101, and a hole is opened along the tangent direction of the dust-laden airflow as the dust outlet 107. The two dust outlets 107 stacked up and down can ensure that both larger and smaller dust can be effectively discharged from the first outer wall 101, thereby improving the dust removal efficiency and extending the service life of the filter element.

[0038] In order to prevent the external environment from affecting the first boost purification device 100, the present application provides a shielding portion 108 at the first end 110 of the first outer wall 101. The shielding portion 108 can cover the air inlet end of the first outer wall 101, and a variety of structures can be selected, such as a common rain cap structure.

[0039] like Figure 7 As shown, the pressurized purification system of the present application further includes an air exchange device 200 and a second purification device 300. The air outlet of the first pressurized purification device 100 is connected to the first air inlet of the air exchange device 200, and the second purification device 300 is connected to the second air inlet of the air exchange device 200. The first pressurized purification device 100 of the present application passes the air outside the operating room through the air inlet of the air exchange device 200 after pressurization filtration, and enters the operating room to pressurize the operating room. The air exchange device 200 can be an air conditioning device.

[0040] like Figure 6 As shown, the second purification device 300 includes a second outer wall 301 and a second filter 302. The second filter 302 is arranged inside the second outer wall 301. A third cavity 310 is provided between the second filter 302 and the second outer wall 301. The cylindrical wall of the second filter 302 forms a fourth cavity 320. The gas before purification is sent into the third cavity 310. After the gas is filtered by the second filter 302, it is sent into the fourth cavity 320. The purified gas is sent out from the second air outlet 306 of the fourth cavity 320. In addition, a second air supply device 303 is provided at the air inlet of the second purification device 300. The second air supply device 303 is used to send the air in the operating room into the third cavity 310.

[0041] The second purification device 300 is also provided with a second fixing portion 304, which is arranged between the second air supply device 303 and the second filter 302. A plurality of second swirl blades 305 are arranged on the periphery of the second fixing portion 304, and the second swirl blades 305 have an inclination angle along the airflow direction, such as a 45° inclination angle.

[0042] In order to facilitate real-time monitoring of the air quality in the operating room, the structure of the present application also includes a monitor 400, which is used to monitor the pressure and carbon dioxide concentration in the environment. The detection results are as follows: Figure 8 As shown, the air intake volume of the first boost purification device 100 and the second purification device 300 can be controlled according to the detection result of the monitor 400.

[0043] The working method of the boost purification system of the present application is: the first air supply device 103 of the first boost purification device 100 rotates at a high speed, the external air is rotated at a high speed through the first swirl blade 105, and the dust-containing airflow rotates forward along the wall surface of the first outer wall under the action of centrifugal force and reaches the dust collecting groove 109, where it is captured and then discharged through the dust exhaust port 107. This can effectively reduce the filtering load of the first filter 102 and increase the life of the filter element. The air that has been filtered and pressurized by the first air supply device 103 is discharged through the first air outlet 106.

[0044] The air purified by the first boost purification device 100 is sent to the air exchange device 200, and then sent into the operating room through the air outlet of the air exchange device 200.

[0045] The second purification device 300 is installed at another air inlet of the ventilation device 200. After being purified by the second purification device 300, the air in the operating room is sent into the operating room again through the air outlet of the ventilation device 200. The air containing pollutants in the operating room is filtered by the filter element of the second filter device 302 and then discharged through the air outlet, thereby purifying the air in the operating room. After the second filter device 302 in the second purification device 300 reaches its service life, the filter element can be replaced.

[0046] The CO2 concentration, inhalable pollutant concentration, and positive pressure in the operating room are monitored in real time through the monitor 400. When a parameter exceeds the ISO23875 standard range, the corresponding text is displayed in red, and a sound alarm signal is output; when a parameter meets the ISO23875 standard requirements, the corresponding text is displayed in green, and the alarm signal disappears. The monitoring controller has two outputs at the same time, which control the speed of the motors of the air supply devices in the first boost purification device 100 and the second purification device 300, and can adjust the air intake of the two air supply devices according to the air conditions in the operating room.
