[0092] like Figure 2 As shown, the discharge structure 5 includes a first channel 51, a second channel 52 and a third channel 53; the second channel 52 is arranged between the first channel 51 and the third channel 53; wherein the upstream end of the first channel 51 is connected to the outlet 12, the liquid discharge port 13 is arranged in communication with the first channel 51, and the liquid discharge port 13 is arranged on the side of the first channel 51 close to the ground in the height direction; the second channel 52 is extended in the height direction. The airflow discharged from the outlet 12 in a one-way flow is diverted and processed in sequence by the first channel 51, the second channel 52 and the third channel 53. In this embodiment, the first channel 51 is extended in the horizontal direction, and the first channel 51 can be assembled on the ground side; the second channel 52 is arranged vertically in the height direction, and the third channel 53 is extended in the horizontal direction. In some embodiments, the first channel 51 and the housing 1 are configured as an integral structure; in other embodiments, an assembly cavity for installing the first channel 51 is arranged near the ground side in the housing 1, the first channel 51 is configured as a sealed exhaust pipe, the sealed exhaust pipe is installed in the assembly cavity, and the sealed exhaust pipe and the outlet 12 are arranged in communication.

[0093] In some embodiments, Figure 2 As shown, the mist shower purification device also includes a third filter 54 and a second filter 55 which are arranged in series on the exhaust path of the exhaust structure 5. The third filter 54 is installed in the upstream direction of the exhaust structure 5 relative to the second filter 55. The third filter 54 can be a high-efficiency filter to filter foreign particles in the exhaust path of the exhaust structure 5; the second filter 55 can be a bag-in-bag-out filter system to process and collect the circulating exhaust gas in the exhaust path and centrally process the pollutants. The third filter 54 and the second filter 55 are arranged at the third channel 53.

[0094] The mist shower purification device provided in this embodiment has a gas-liquid separation design integrated in the first channel 51 at the bottom of the outlet 12. Figure 2 As shown, the first channel 51 has a guide wall inclined with respect to the horizontal plane, and the guide wall is suitable for guiding the liquid to the drain port 13. The guide wall provided in the first channel 51 guides the liquid flowing from the outlet 12 into the first channel 51 to the drain port 13, thereby promoting the rapid discharge of the liquid in the purification chamber.

[0095] See also Figure 6The mist shower purification device is equipped with a grid member 16, which is installed on the outlet 12 and arranged in the horizontal direction; the grid member 16 is set as a hollow structure, and the discharge structure 5 and the purification chamber are connected through the hollow space on the grid member 16 to discharge the fluid in the purification chamber.

[0096] See also Figure 6 and Figure 7 , a design for collecting liquid after mist shower treatment is arranged in the first channel 51 at the bottom of the outlet 12; a drain pan 17 is installed in the first channel 51, and the drain pan 17 is installed at intervals in the direction where the outlet 12 is away from the air inlet 11. The drain pan 17 is arranged obliquely with respect to the horizontal plane, and the water receiving side of the drain pan 17 is suitable for guiding the liquid to the drain port 13, and the drain port 13 is arranged away from the exhaust direction of the first channel 51. The liquid discharged from the outlet 12 is guided to the drain port 13 through the drain pan 17, so as to achieve the purpose of quickly discharging the liquid in the purification chamber.

[0097] Furthermore, the drain pan 17 and the grille 16 are arranged at intervals, and the horizontal projection surface of the drain pan 17 is larger than the horizontal projection surface of the grille 16, so as to cover the mixed fluid of the airflow and the mist liquid from top to bottom passing through the grille 16 in a large range, so that the drain pan 17 can collect the mist liquid; a discharge space is formed between the grille 16 and the drain pan 17, and the vertical projection distance from the grille 16 to the drain pan 17 along the gravity direction is 50mm-70mm. When the drain pan 17 needs to be dried, the laminar air supply of the air supply unit 3 and the exhaust effect of the exhaust structure 5 are used to make the circulating air flow take away the residual liquid in the drain pan 17 to achieve the purpose of drying.

[0098] The mist shower purification device provided in this embodiment optimizes the air outlet structure, configures the outlet 12 to be connected to the grille member 16 on the bottom side of the mist shower chamber, and simultaneously provides the air supply unit 3 and the exhaust structure 5 to improve the laminar air flow in the mist shower chamber, which can accelerate the drying of the drain pan 17 at the bottom; after an air shower drying test, in the second working state, the drain pan 17 at the bottom is completely dry after 10 minutes, and there are no water droplets visible to the naked eye.

[0099] In the horizontal plane extending direction, the flow cross-sectional area of ​​the outlet 12 is smaller than the flow cross-sectional area of ​​the purification chamber.

[0100] In some embodiments, the device further comprises a sandwich structure, and the air supply unit 3 and the third channel 53 are arranged in the sandwich structure. The sandwich structure can be configured as a technical sandwich, installed indoors, and cooperate with the indoor wall surface to form an auxiliary space for installing and assembling the device. The air supply unit 3 and the third channel 53 are closed by the sandwich structure to reduce the risk of drug dust contamination.

[0101] like Figure 1 and Figure 2As shown, the driving structure also includes a second driving member 42, which is arranged on the exhaust path of the exhaust structure 5; the second driving member 42 increases the drainage effect of the one-way flow of the device, speeds up the flow rate of the fluid in the purification chamber, reduces the drug dust and the residual water vapor in the purification chamber, and ensures reliable purification and humidity control. The second driving member 42 is installed on the third channel 53.

[0102] In this embodiment, the first driving member 41 is configured as a laminar flow fan, which outputs a fixed wind speed. The laminar flow wind speed output by the first driving member 41 is 0.36-0.54 m / s. The laminar flow wind drives the mist shower liquid to approach the drug dust on the clean clothes so that it can adhere to the clean clothes to avoid the drug dust from causing harm to the human body when the clean clothes are replaced later. The second driving member 42 is configured as a variable frequency exhaust fan, which has a variable frequency output wind speed. The fluid force output by the first driving member 41 is less than the fluid force output by the second driving member 42. In overcoming the resistance of the flow path, a pressure difference gradient is generated between the purification chamber where the first driving member 41 is located and the third channel 53 where the second driving member 42 is located, so that the laminar flow wind and the mist shower liquid flow from top to bottom in the purification chamber to the first channel 51, and then flow to the second channel 52 and the third channel 53 in turn.

[0103] It should be noted that the mist shower room provided in this embodiment is located in the GMP negative pressure environment of the pharmaceutical production workshop; during the mist shower ventilation process, the pressure difference generated by the negative pressure is used to seal the closed door body to avoid convection between the air inside the mist shower room and the outside air; and the pressure difference is used to make the gas pressure on both sides of the first door body 81 and the second door body 82 used for entering and exiting the mist shower purification device when the operator leaves the buffer zone is greater than the fluid pressure in the purification chamber of the mist shower purification device, thereby ensuring that other areas will not be contaminated in the purification chamber when the door is opened.

[0104] The mist shower purification device provided in this embodiment can increase the output wind speed of the second driving member 42 to increase the air flow velocity of the purification chamber and the exhaust path of the exhaust structure 5, which is beneficial to enhance the ventilation capacity of the purification chamber; taking the lower laminar flow wind speed of 0.36m / s in the purification chamber as an example, the length of the purification chamber is set to 1 meter, the width is set to 1 meter, the height is set to 2 meters, and its volume is 2 cubic meters. The length of the outlet 12 is set to 0.9 meters and the width is set to 0.7 meters. The ventilation frequency F of the purification chamber per cubic meter per hour is equal to (0.9×0.7×0.36×3600) / 2, which is equivalent to 408 times / hour / cubic meter, which is equivalent to 6.8 times per minute. The mist shower purification device has excellent ventilation effect and good circulation and drying ability.

[0105] In this embodiment, the first driving member 41 is used to output laminar air flow, and the joint drainage effect of the second driving member 42 is helpful to avoid turbulence of the air flow, which affects the wetting and wrapping treatment of toxic drug dust by the mist shower liquid; the mist shower purification device adopts the bottom return air and unidirectional vertical laminar flow, which improves the ability to mist and dry clean clothes and purification chambers, and can make the purification chamber have good cleanliness, which is helpful to reduce the risk of drug contamination. Compared with the existing mist shower room, it solves the problem of water droplets easily remaining in the chamber and the risk of drug contamination; for example, when the existing mist shower room adopts lateral exhaust, its drying capacity is insufficient, and more water droplets remain on the bottom side of the chamber, which will cause the residue of toxic powder, and the operator's feet are easy to stick to the toxic powder, and when entering and leaving the mist shower room, the toxic powder will be spread along the path, which poses a risk of product contamination.

[0106] like Figure 2 As shown, the mist shower purification device also includes a first pressure regulating member 61 and a second pressure regulating member 62. The first pressure regulating member 61 is installed on the air supply path of the air supply unit 3, and the first pressure regulating member 61 is used to adjust the air supply volume of the air supply unit 3; the second pressure regulating member 62 is installed on the exhaust path of the exhaust structure 5, and the second pressure regulating member 62 is used to adjust the exhaust volume of the exhaust structure 5. The air supply volume of the air supply unit 3 is adjusted by the first pressure regulating member 61, and the exhaust volume of the exhaust structure 5 is adjusted by the second pressure regulating member 62, so that the opening and closing and the corresponding air pressure flow rate can be adjusted according to the use requirements, which is conducive to improving the convenience of debugging, so as to meet the pressure difference control requirements of the desired design, and thus better adapt to the airflow pressure and airflow velocity required in the purification stage of the device.

[0107] The mist shower purification device provided by the present invention is used as follows:

[0108] The device can be configured between the drug production line area and the peripheral area, and the mist shower purification device can be configured when entering the production line area from the peripheral area and when leaving the production line area and entering the peripheral area;

[0109] When the device is performing self-cleaning operation, the device is first set to the first working state, the first door body 81 and the second door body 82 are locked, the air supply unit 3 delivers airflow, the first nozzle member 22 and the second nozzle in the mist shower assembly 2 spray out atomized purification liquid, and the first drive member 41 and the second drive member 42 drive the drainage, so that the fluid in the purification chamber flows unidirectionally along the direction from the air inlet 11 to the outlet 12, so as to perform mist shower treatment on the purification chamber, and the gaseous fluid flowing out of the outlet 12 is transported and collected accordingly through the discharge structure 5; the liquid fluid flowing out of the outlet 12 is guided to the liquid discharge port 13 through the guide wall of the first channel 51; after closing the mist shower, the device is first set to the second working state, and air supply and exhaust drying are performed. The drying time range is configured according to actual needs. After no liquid droplets remain in the purification chamber, the self-cleaning operation is completed;

[0110] When the device is performing mist shower purification operation, the staff wearing clean clothes enters the purification chamber in the shell 1, the first door body 81 and the second door body 82 are locked, and the device is set to the first working state to perform a working process similar to the above-mentioned self-cleaning operation. The staff can rotate in the purification chamber to make the laminar mist shower fully cover the clean clothes, and the drug dust is attached and wrapped by the mist shower liquid, so that it falls into the first channel 51 toward the outlet 12 under its own gravity and the action of the airflow. The airflow is filtered and processed by the third filter element 54 and the second filter element 55 of the discharge structure, and the collected liquid flow is discharged to the outside through the drain port 13; after the mist shower is completed, the device is switched to the second working state to dry the residual mixed liquid on the clean clothes and in the purification chamber with air shower. After drying, the second door body 82 is opened again to allow the staff to enter or leave the production line area, and then the device can perform self-cleaning operation again; the staff puts the wet clean clothes in an external collection device for further processing.

[0111] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
