Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
The invention provides a method for creating a partitioned environment for preventing cross contamination of an office by pressing, separating and pumping in order to solve the problem of low utilization efficiency of clean air in the traditional airflow organization mode at present and combine an air supply mode of feeding air from top to bottom and a personnel fixing position. As shown in fig. 1, the method comprises the steps of:
an air supply outlet is arranged on the ceiling above the mouth and the nose of each person;
arranging a partition plate with three sides surrounding each person, wherein the opening side of the partition plate is close to the wall surface;
an air outlet is formed in the wall surface surrounded by the partition plate.
The method of the invention fully utilizes the functions of air supply and air exhaust, can improve the safety of offices and the air quality of the breathing zone of personnel, and simultaneously enhances the removal efficiency of pollutants by assisting the partition board.
Furthermore, the air supply outlet is a louver air opening, and the air supply direction can be adjusted through rotation.
Further, the air outlet has the telescopic hose, can adjust the position of air outlet according to pollutant concentration distribution condition.
Further, but the baffle is height-adjusting's flexible baffle, the distance is predetermine to the use height of baffle over personnel's head height, the rear portion of baffle or the lateral part that does not lean on one side of the wall is provided with the door of switch.
Furthermore, the partition plate is made of transparent materials, angle-adjustable louvers are arranged in the partition plate, and the angle of the louvers can be adjusted according to the requirements of people so as to adjust the transparency of the partition plate.
Specifically, in the embodiment of the invention, the air supply outlet is arranged on the ceiling above the mouth and the nose of each person, so that fresh air firstly reaches the breathing zone of the person, the high air quality of the breathing zone of the person is ensured, meanwhile, the thermal plume of the person is suppressed, and pollutants generated by the person are downwards discharged. In order to give consideration to the comfort of personnel and avoid the blowing feeling caused by air supply and direct blowing, the air supply port is in a shutter air port mode, the air supply angle can be adjusted, the air supply direction is changed according to the requirement of personnel in the ordinary period, and the air supply port is adjusted to be directly sent to the mouth and the nose of the personnel during virus outbreak so as to achieve the maximum protection effect. The air outlet is arranged on the inner wall surface of the partition board near the personnel and is provided with a telescopic hose to adjust the air exhaust position, so that the air outlet is ensured to pump away pollutants in time at the place with the highest pollutant concentration. The baffle is installed around personnel, for transparent material, but built-in angle regulation's tripe makes the baffle compromise security and privacy nature simultaneously. The partition board has a lifting function so as to switch the height of the partition board at different periods. The air flow organization can improve the safety of offices on the premise of not increasing energy consumption, and is simple to install and modify.
Taking fig. 1 as an example, in a small office with four people, the people are located at fixed stations, respectively. Each personnel head top is provided with an air supply outlet, the periphery of the head top is provided with a partition plate, and the wall surface near the inside of the partition plate is provided with an air outlet. In this embodiment, the size of the office is 5m (length) × 4m (width) × 3m (height), the height of the partition is 1.6m, and the partition can be opened at the side or the back for people to enter and exit. The air outlet is arranged close to the wall surface at the side of the personnel body, the telescopic pipeline is in a completely contracted state, and the sizes of the air supply outlet and the air outlet are both 0.25m multiplied by 0.25 m.
To demonstrate the improvement of the present invention, the present invention is compared with the conventional air flow feeding and returning organization, and fig. 2 is a schematic diagram of an office layout of the conventional air flow feeding and returning organization. The virus outbreak period was taken as an example and the number of times of ventilation of the room was 10 times/h, that is, the blowing speed per blowing port was 0.67 m/s. Assuming one of the persons has infected and released the virus, two virus concentrations are obtained below the tissues of the airflow across the plane of the person's breathing zone, as shown in figures 3 and 4.
As can be seen from fig. 3 and 4, the virus spreads in the room under the conventional airflow organization, and the respiratory region of other people is high in concentration. In the airflow organization form of the invention, most of viruses are pressed by the air supply jet flow and are pumped away by the air outlet, and the partition board also blocks the diffusion of the viruses, so that the virus concentration in the partition board area of other personnel is reduced to below 1E-5. Compared with the traditional airflow tissue form, the concentration of pollutants at the mouth and the nose of uninfected people is respectively reduced by 81.33%, 77.08% and 84.18%, and the average reduction is 80.86%.
As can be seen from the simulation comparison, the air flow tissue form of the invention is superior to the traditional air flow tissue form, the virus concentration at the mouth and nose of the uninfected person is obviously reduced, the infection probability of the uninfected person is reduced, and the method is an effective indoor environment protection method.
Accordingly, an embodiment of the present invention further provides an office partition environment creation system for preventing cross contamination, including: the setting is at the supply-air outlet of each personnel mouth nose top ceiling department, sets up around each personnel and trilateral baffle that centers on, the opening side of baffle is close to the wall, and sets up the exhaust outlet of the wall department that the baffle surrounds.
Furthermore, the air supply outlet is a louver air opening, and the air supply direction can be adjusted through rotation.
Furthermore, the air outlet is provided with a telescopic hose, so that the air exhaust position can be adjusted according to the pollutant concentration distribution condition.
Further, the baffle is but height-adjusting's flexible baffle, the use height of baffle is higher than personnel's head height and is predetermine the distance, the rear portion of baffle or the lateral part that does not lean on one side of the wall is provided with the door of switch.
Furthermore, the partition plate is made of transparent materials, angle-adjustable louvers are arranged in the partition plate, and the angle of the louvers can be adjusted according to the requirements of people so as to adjust the transparency of the partition plate.
The system of this embodiment may be used to implement the technical solutions of the above method embodiments, and the implementation principles and technical effects are similar, which are not described herein again.
In summary, the invention provides a method and a system for creating a partitioned environment for preventing cross contamination of an office by combining an air supply form of up-supply and down-return with a personnel fixing position, aiming at the problem that the utilization efficiency of clean air is low in the traditional air flow organization form at present, fully utilizing the functions of air supply and air exhaust, improving the safety of the office and the air quality of a respiratory area of personnel, and simultaneously assisting with a partition plate to enhance the removal efficiency of pollutants. The improvement effect of the method provided by the invention is verified by the simulation comparison of the office partition environment construction method provided by the invention and the traditional airflow organization form.
