Detailed Description
In order that those skilled in the art will better understand the present application, a technical solution in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in which it is apparent that the described embodiments are only some embodiments of the present application, not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the present application without making any inventive effort, shall fall within the scope of the present application.
Referring to fig. 2-9, the present invention provides a clean room air supply ceiling, which aims to prevent air flow collision, further avoid energy waste and reduce use cost on the premise that air flows conveyed by a plurality of total air inlets 500 form convolutions in a main box 100. It includes a main housing 100, an air flow compensation plate 200, a plurality of filter housings (not shown) and filters (not shown) disposed in the filter housings, the main housing 100 having a rectangular hollow structure with a square bottom surface. Wherein, the filter is used for filtering the gas entering the main housing 100, the gas flow compensation plate 200 comprises a support frame, a plate body and a plurality of gas flow holes, and the gas flow compensation plate 200 is used for uniformly discharging the gas flow in the main housing 100 from the main housing 100. The filter and the airflow compensation plate 200 are all of the prior art, and will not be described in detail herein.
The main housing 100 is provided at 4 sides thereof with a total air inlet 500, and the filter is installed at the total air inlet 500 through the filter housing. The four sides in the main box 100 are all provided with drainage mechanisms connected with the corresponding main air inlets 500. The drainage mechanism comprises a first drainage channel 300 and a second drainage channel 400, wherein the first drainage channel 300 is arranged on one side of the total air inlet 500, and the first drainage channel 300 is provided with a first air inlet 310 and a first air outlet 320. The plane of the first air inlet 310 is perpendicular to the side wall of the main box body 100 where the corresponding total air inlet 500 is located, the plane of the first air outlet 320 is at an acute angle with the side wall of the main box body 100 where the corresponding total air inlet 500 is located, the direction from the first air inlet 310 to the first air outlet 320 of the first drainage channel 300 comprises a tapered necking section 330, a throat section 340 and a flaring section 350 which is gradually widened, the second drainage channel 400 is provided with a second air inlet 410 connected with the total air inlet 500, and a second air outlet 420 extending into the necking section 330 of the first drainage channel 300, and the first air outlets 320 and the first air inlets 310 respectively provided by two adjacent first drainage channels 300 are oppositely arranged.
When the air filter is used, air conveyed from the outside firstly enters four filter boxes, and is filtered by filters arranged in the four filter boxes, so that the air is ensured to be clean; four air flows are filtered and then enter the second drainage channel 400 of the corresponding drainage mechanism through the total air inlet 500, and flow along the second drainage channel 400 from the second air inlet 410 to the second air outlet 420 until being discharged from the second air outlet 420 of the second drainage channel 400; the discharged air enters the first drainage channel 300 and sequentially passes through the necking section 330, the throat section 340 and the gradually-expanding flaring section 350 to be discharged from the first air outlet 320 into the main box body 100; in this process, as the air passes through the throat section 340, the dynamic pressure reaches a maximum and the static pressure reaches a minimum due to the narrowest point of the first flow-directing channel 300, and the velocity of the air increases due to the reduced cross-sectional area of the flow. According to Bernoulli's principle, the pressure of the throat section 340 is reduced at the same time, so that a pressure difference is generated between the throat section 340 and the necking section 330, and air in the necking section 330 flows towards the throat section 340, so that an external suction force is generated in the necking section 330 of the first drainage channel 300, and air flow discharged by the drainage mechanism flows towards the necking section 330 of the adjacent first drainage channel 300 in a counterclockwise direction. As shown in fig. 8, the air flow entering the main box 100 is caused to swirl, and in addition, the air flow of the plurality of total air inlets 500 is not collided and disturbed, and the swirling flow rate of the air is also significantly improved, so that the air flow of the air supply ceiling is more uniform.
As shown in fig. 8, in this embodiment, the second drainage channel 400 includes an arc-shaped section 430 connected to the main air inlet 500, and a parallel section 440 connected to the arc-shaped section 430 and parallel to the side wall of the main housing 100 corresponding to the main air inlet 500. Based on the above design, the air flow discharged from the second flow guiding channel 400 is parallel to the side wall of the main box body 100 corresponding to the total air inlet 500, so when the air enters the first flow guiding channel 300 and is discharged from the first flow guiding channel 300, most of the air flows toward the main box body 100 at an included angle, which can increase the swirling path of the air in the main box body 100, so that the swirling path of the air is closer to the rectangle, and the air flow of the air supply ceiling is more uniform.
In this embodiment, the cross section of the first air outlet 320 is larger than the cross section of the first air inlet 310. Based on this design, the flow rate of the air flow discharged from the first air outlet 320 is reduced, the air pressure at the first air outlet 320 is correspondingly increased according to the bernoulli principle, and the air pressure refers to the air pressure acting on the unit area, that is, the air pressure acting on the inner wall of the second air outlet 420, when the air flow is discharged from the first air outlet 320, the blocking of the inner wall of the second air outlet 420 is lost, and the air flow is diffused to the periphery, so that the air flow diffusion area is increased.
In this embodiment, the cross section of the second drainage channel 400 from the second air inlet 410 to the second air outlet 420 is gradually decreased. Based on this design, the flow rate of the gas discharged from the second drainage channel 400 is increased, thereby increasing the flow rate of the gas at the throat, increasing the differential pressure value, and increasing the attractive force.
As shown in fig. 9, in this embodiment, the first drainage channel 300 is inclined downward from the first air inlet 310 to the first air outlet 320. Based on the design, the air exhausted by the four drainage mechanisms forms four longitudinal spirals in the main box body 100, the overall height of the swirling air flow is improved, and the air flow of the air supply ceiling is more uniform.
In this embodiment, the included angle between the plane of the first air outlet 320 and the side wall of the main box 100 where the corresponding total air inlet 500 is located is 30 ° -45 °, and preferably, the included angle between the plane of the first air outlet 320 and the side wall of the main box 100 where the corresponding total air inlet 500 is located is 30 °.
In this embodiment, four high-flux pulsed xenon lamps 600 are installed at the middle position inside the main box, and the light emitting surfaces of the four high-flux pulsed xenon lamps 600 face to four corners inside the main box respectively. The pulsed xenon light is a novel cold sterilization technology, which instantaneously releases the electric energy accumulated in a super-large capacity capacitor, and generates pulsed strong light with the energy of up to 2J/c square meter for only 10-100 ms continuously through high-purity xenon gas in a high-voltage ionization lamp tube, so that various pathogens can be effectively destroyed, the sterilization effect is achieved, and the air quality in an operating room is improved.
Specifically, the high-flux pulsed xenon lamp 600 includes a control unit, a power unit, a trigger unit, and a processing unit. The power unit provides high-voltage high-current energy for the xenon lamp and triggers xenon ionization; after the energy storage capacitor is charged for a relatively long time (hundreds ms), discharging is carried out in an extremely short time (tens to hundreds mu s), the discharging voltage causes the xenon avalanche ionization in the lamp tube, the xenon converts and releases the charged energy in the form of high-intensity light radiation, and the discharging process is a light pulse; the control module can enable the pulse xenon lamp to start and stop at any time, and the reaction is rapid, so that the requirement of the pulse xenon lamp on the opening at any time cannot be met, and in special occasions, such as the process of packaging protein medicines, the protein is denatured due to ultraviolet rays, so that the products need to be accurately controlled when being sterilized.
The foregoing is only a preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art, who is within the scope of the present invention, should make equivalent substitutions or modifications according to the technical scheme of the present invention and the inventive concept thereof, and should be covered by the scope of the present invention.
