Description

Technical Field

[0001] This utility model relates to the field of decontamination equipment technology, specifically to a circulating water curtain type personnel pre-washing chamber. Background Technology

[0002] Disinfection is a core technology that uses physical, chemical, or biological methods to remove or kill contaminants (such as dust, grease, and organic matter), pathogenic microorganisms (bacteria, viruses, fungi, etc.), or harmful chemicals (such as pesticide residues and chemical toxins) on the environment, objects, human (or animal) surface and mucous membranes, thereby reducing health risks and ensuring hygiene and safety.

[0003] In personnel decontamination procedures, the pre-rinsing stage is a crucial step in removing large particulate contaminants from surfaces. Currently, commonly used pre-rinsing methods include high-pressure spray pre-rinsing, immersion disinfection tank pre-rinsing, and aerosol pre-cleaning; however, each of these methods has the following drawbacks: Firstly, high-pressure spray pre-washing consumes a large amount of water and is difficult to operate continuously in water-scarce areas; splashing water droplets can easily lead to secondary pollution risks; wastewater cannot be recycled, and rinsing water containing pathogens is directly discharged.

[0004] Secondly, the immersion disinfection pool pre-washing method results in: the disinfectant concentration decreases and needs to be changed frequently; it can only treat the soles of shoes and cannot clean the whole body; and dirt accumulates at the bottom of the pool, becoming a source of cross-infection.

[0005] Third, aerosol pre-cleaning: Disinfecting aerosol is sprayed through atomizing nozzles, but it has a low removal rate for highly adhesive particles (such as dirt and bloodstains); the atomized particles are easily inhaled, posing a risk of respiratory irritation.

[0006] Therefore, the pre-washing methods in related technologies still need to be improved in order to avoid the various defects and shortcomings mentioned above. Utility Model Content

[0007] The purpose of this invention is to overcome the above-mentioned technical deficiencies and propose a circulating water curtain type personnel pre-washing chamber to solve the technical problems of excessive water consumption, easy secondary pollution, inability to recycle wastewater, and insufficient pre-washing effect in the existing technology.

[0008] To achieve the above-mentioned technical objectives, the present invention adopts the following technical solution: This utility model provides a circulating water curtain type personnel pre-washing chamber, including: The cabin is designed to accommodate pre-washed personnel; A water collection structure is located at the bottom of the inner side of the chamber to collect wastewater generated during pre-washing; A water treatment system, connected to the water collection structure via pipelines, is used to collect wastewater and purify it; and A nozzle array, positioned at the top inside the pre-wash zone and connected to the water treatment system via piping, is used to form a mist. The chamber includes at least: Equipment room, used for equipment installation; The decontamination room, which is equipped with the aforementioned water collection structure and nozzle array, is used to accommodate pre-washing personnel; and A partition is fixedly installed inside the cabin to isolate the equipment room from the decontamination room.

[0009] In some embodiments, the water collection structure includes: Multiple diversion channels are installed on the bottom surface of the decontamination room to receive and collect wastewater; and A water collection tank is located at the bottom of the washing and disinfection room and is connected to the multiple diversion channels for the centralized collection of wastewater.

[0010] In some embodiments, the water treatment system includes: A wastewater tank, connected to the water collection structure via pipes, is used to recycle wastewater; A submersible pump is connected to the water collection structure and the sewage tank via pipelines, and is used to recycle the wastewater collected by the water collection structure into the sewage tank. A filtration device, connected to the wastewater tank via a pipeline, is used to filter pollutants in the wastewater; A disinfection device, connected to the filtration device via pipeline, is used to disinfect the filtered wastewater to obtain purified water; and A high-pressure water pump is connected to the disinfection device and the nozzle array via pipelines, and is used to deliver purified water to the nozzle array.

[0011] In some embodiments, the filtration device includes: An internal filter screen is installed inside the wastewater tank to initially filter large particulate impurities; and A filter, connected to the wastewater tank via a pipeline, is used to adsorb colloids for secondary treatment.

[0012] In some embodiments, the disinfection device includes an electrolytic sterilization module for electrolytic disinfection, and the electrolytic sterilization module is further provided with an ultrasonic disinfection module.

[0013] In some embodiments, the nozzle array includes a plurality of slit nozzles connected to the water treatment system via pipelines and evenly spaced in the lateral direction of the washing and disinfection room to form a thin mist water curtain along the lateral direction of the washing and disinfection room.

[0014] In some embodiments, the prewash tank further includes a piping system, the piping system comprising: The first connecting pipe is used to connect to the water treatment system; A second connecting pipe is used to connect the first connecting pipe to the nozzle array; and A pipe cover is fixedly installed on the top of the inside of the cabin to cover the first connecting pipe and / or the second connecting pipe.

[0015] In some embodiments, the cabin is a movable cabin.

[0016] In some embodiments, the cabin is equipped with a protective door at the entrance of the decontamination room to isolate the external space from the decontamination room.

[0017] Compared with the prior art, the present invention provides a circulating water curtain type personnel pre-washing chamber, which collects wastewater generated during the pre-washing process by setting a water collection structure at the bottom of the chamber. The wastewater is then transported to a water treatment system through pipelines. The water treatment system purifies the wastewater and finally transports it to a nozzle array through pipelines. The nozzle array sprays purified water into the chamber and forms a thin mist water curtain to pre-wash the personnel.

[0018] In this way, the mist water curtain can reduce ineffective water flow while ensuring impact force, which greatly reduces water consumption per person and significantly improves water-saving efficiency. The water curtain shape can concentrate and cover the effective area without causing secondary pollution. By controlling the impact force of the water curtain, the pre-washing effect can be guaranteed and the pre-washing efficiency can be improved. While ensuring water safety, water recycling can be realized, which can meet the needs of water-scarce areas and help expand the application scenarios. Attached Figure Description

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0022] To address the aforementioned technical problems, this utility model provides a circulating water curtain type pre-washing chamber for personnel, which not only avoids secondary pollution during pre-washing, ensures the pre-washing effect, and improves pre-washing efficiency, but also achieves water recycling while ensuring water safety, significantly improving water-saving efficiency and meeting the needs of water-scarce areas.

[0023] Please see Figure 1 This utility model provides a circulating water curtain type personnel pre-washing cabin, which includes a cabin body 1, and a decontamination room 11 and an equipment room 12 are respectively arranged inside the cabin body 1. The decontamination room 11 can be used to accommodate pre-washing personnel, while the equipment room 12 can be used to install equipment.

[0024] In this embodiment, the cabin 1 can be configured as a rectangular cavity structure, or it can be configured as other structural forms as needed. Furthermore, the specific dimensions of the cabin 1 can be flexibly set according to the requirements of the application, and are not specifically limited thereto.

[0025] Combined with appendix Figure 2 A partition 2 is fixedly installed inside the cabin 1. The partition 2 and the inner wall of the cabin 1 can form a separate equipment room 12, which can be used to install equipment. The part of the cabin 1 located outside the partition 2 can form a decontamination room 11. The specific dimensions and proportions of the equipment room 12 and the decontamination room 11 inside the cabin 1 can be flexibly set according to needs and are not specifically limited.

[0026] To facilitate personnel access to and from the decontamination room 11, an entrance to the chamber 1 can be provided on the side of the decontamination room 11 away from the equipment room 12, and a protective door (not shown in the figure) can be movably installed at this entrance. This protective door can be a roller shutter door, a double door, or any other protective structure; there are no specific limitations on this. Of course, in some embodiments, the two sides along the length of the chamber 1 can be respectively designated as an entrance and an exit; in this case, the aforementioned protective doors can be installed at the entrance and exit respectively.

[0027] Based on this, the decontamination room 11 is equipped with a nozzle array 3 and a water collection structure 4, and the equipment room 12 is equipped with a water treatment system 5. The nozzle array 3 can spray water mist in the decontamination room 11 to pre-wash the personnel; the water collection structure 4 can collect the wastewater in the decontamination room 11 and transport it to the water treatment system 5; the water treatment system 5 can treat and purify the collected wastewater and supply the purified water to the nozzle array 3, thereby realizing water recycling.

[0028] Please see Figure 2 The aforementioned water collection structure 4 may include multiple guide channels 41 and a water collection tank 42. The multiple guide channels 41 can be installed on the bottom surface of the decontamination room 11 and are interconnected; while the water collection tank 42 can be installed at any location within the decontamination room 11 near the equipment room 12, facilitating connection to the water treatment system 5 in the equipment room 12 via pipelines. Its specific location can be determined based on the arrangement of equipment within the equipment room 12 and is not specifically limited here. Simultaneously, the water collection tank 42 can be configured as an independent water tank with an open top, connected to each guide channel 41.

[0029] Understandably, the diversion channel 41 can be used to receive and collect the wastewater generated during the pre-washing process, and divert the wastewater to the collection tank 42, which can serve as a centralized temporary storage for the wastewater.

[0030] Therefore, within the decontamination room 11, each guide channel 41 can be appropriately tilted according to the location of the water collection tank 42, so that the wastewater falling on the guide channel 41 can flow smoothly into the water collection tank 42 along the guide channel 41. The water collection tank 42 itself is preferably set at a relatively low position within the decontamination room 11 to facilitate comprehensive collection of wastewater.

[0031] Please see Figure 3 The aforementioned water treatment system 5 includes a submersible pump 51 installed in a collection tank 42. The inlet of the submersible pump 51 is connected to the collection tank 42, and its outlet is connected to a wastewater tank 52 via a pipeline. The wastewater tank 52 can be fixedly installed in the equipment room 12 near the collection tank 42 for easy pipeline connection. The wastewater tank 52 is also connected in sequence to a filter device and a disinfection device 54 via pipelines. The filter device and the disinfection device 54 can sequentially filter and disinfect the wastewater to achieve wastewater purification.

[0032] Specifically, the aforementioned filtration device may include a built-in filter screen (not shown in the figure) and a filter 53. The built-in filter screen may be fixedly installed inside the wastewater tank 52, and preferably installed at the inlet of the wastewater tank 52; when wastewater enters the wastewater tank 52 from the collection tank 42 along the pipeline, the built-in filter screen can initially filter large particulate impurities in the wastewater to achieve preliminary filtration.

[0033] The filter 53 can be independently installed near the sewage tank 52. It can be fixed inside the equipment room 12 and connected to the outlet of the sewage tank 52 via a pipe. The specific model of the filter 53 can be flexibly selected according to needs. For example, in one implementation, the filter 53 can be an integrated sand filter (i.e., an integrated sand filter system), which uses quartz sand as the core filter media and can be combined with anthracite, garnet, and other layered filter media to form a multi-layer filter bed. It can also be equipped with a backwashing system to ensure that the filter 53 can work normally for a long time.

[0034] When the wastewater in the sewage tank 52 enters the filter 53 through the pipeline, the filter 53 can adsorb the colloids in the wastewater and perform secondary filtration of the wastewater, thus completing the secondary treatment of the wastewater.

[0035] The disinfection device 54 can be installed on the side of the filter 53 away from the sewage tank 52, and can be connected to the outlet of the filter 53 via a pipeline. The disinfection device 54 can be any device with disinfection function as needed, but in one embodiment, the disinfection device 54 includes at least an electrolytic sterilization module. The electrolytic sterilization module includes an electrolytic cell with an electrolytic component, which can electrolytically disinfect wastewater by generating effective chlorine through the electrolysis of water.

[0036] In other embodiments, the disinfection device 54 may further include an ultrasonic disinfection module, which can be mounted on the electrolytic cell. Thus, when the electrolytic sterilization module performs electrolytic disinfection on the wastewater, the ultrasonic disinfection module can simultaneously perform ultrasonic disinfection on the wastewater, thereby achieving deep disinfection of the wastewater and obtaining purified water.

[0037] It should be noted that the aforementioned integrated sand filter, electrolytic sterilization module, and ultrasonic disinfection module are all existing technologies in this field, so their specific internal structures will not be described in detail here.

[0038] In addition, the water treatment system 5 also includes a high-pressure water pump 55. The high-pressure water pump 55 can be connected to the outlet of the disinfection device 54 through a pipeline, and also to the aforementioned nozzle array 3 through a pipeline. In this way, the high-pressure water pump 55 can transport the purified water in the disinfection device 54 to the nozzle array 3 through the pipeline, and spray water mist through the nozzle array 3 to pre-wash the personnel.

[0039] Please see Figure 3-4 In this embodiment, the pre-washing chamber also includes a piping system 6. In addition to the pipes in the water collection tank 42 and the water treatment system 5, the piping system 6 also includes a first connecting pipe 61 and a second connecting pipe 62 for connecting the high-pressure water pump 55 and the nozzle array 3.

[0040] The first connecting pipe 61 can be fixed to the inner wall of the chamber 1. One end of the pipe can extend along the inner wall of the chamber 1 towards the location of the high-pressure water pump 55 and connect to the outlet of the high-pressure water pump 55. The other end can extend upward to the top of the inner side of the chamber 1 and extend towards the decontamination room 11. At this time, the section of the first connecting pipe 61 away from the high-pressure water pump 55 is fixed to the top wall of the decontamination room 11, and its end away from the high-pressure water pump 55 is preferably close to the inlet of the chamber 1.

[0041] The second connecting pipe 62 is fixedly installed on the top wall of the decontamination room 11 and is fixedly connected to the end of the first connecting pipe 61 away from the high-pressure water pump 55. The second connecting pipe 62 is preferably installed on the top wall of the decontamination room 11 along the transverse direction of the cabin 1, that is, the second connecting pipe 62 can be parallel to the partition 2 between the decontamination room 11 and the equipment room 12, and its extension direction can be perpendicular to the direction in which the pre-washed personnel enter the decontamination room 11.

[0042] Meanwhile, the piping system 6 may also include a pipe cover 63, which can be detachably fixed to the top of the decontamination room 11 and cover the aforementioned first connecting pipe 61 and / or second connecting pipe 62. The outer surface of the pipe cover 63 (i.e. the surface facing away from the first connecting pipe 61 and / or second connecting pipe 62) is preferably provided as a smooth surface and can be coated if necessary to reduce water droplet adhesion.

[0043] Thus, the pipe cover 63 can shield the first connecting pipe 61 and / or the second connecting pipe 62, preventing water droplets from splashing onto the first connecting pipe 61 and / or the second connecting pipe 62. The water droplets will quickly slide off the surface of the pipe cover 63, reducing the risk of secondary contamination to the pre-washing personnel.

[0044] like Figure 3-4 As shown, the above-mentioned nozzle array 3 may include a plurality of slit nozzles 31, which may be sequentially installed on the second connecting pipe 62, and preferably the slit nozzles 31 are evenly spaced along the transverse direction of the decontamination chamber 11.

[0045] In this way, when the high-pressure water pump 55 starts working, each slit nozzle 31 sprays water mist at the same time, which can form a water curtain-like effect in the decontamination room 11 near the entrance of the cabin 1, which is the "thin mist water curtain" mentioned above.

[0046] Of course, in other implementation scenarios, multiple rows of the above-mentioned slit nozzles 31 can be installed on the top wall of the decontamination room 11 as needed. Each row of slit nozzles 31 can be set with reference to the above-mentioned nozzle array 3 to improve the pre-rinsing effect.

[0047] It is understood that in this embodiment, the impact force of the water curtain formed by the nozzle array 3 can be controlled by the high-pressure water pump 55 and the slit nozzle 31; when the water curtain impact force reaches 15 N / cm 2 When used, it can effectively remove particles larger than 50μm (such as mud, sand, and dust).

[0048] Simultaneously, adding 0.1% biodegradable surfactant to the purified water can remove oily residues from personnel. Furthermore, different agents can be added to water treatment system 5 to specifically treat wastewater for different types of pollution, meeting the needs of various application scenarios.

[0049] It should be noted that the cabin 1 in this embodiment can be a fixed cabin, and the fixed cabin can be set in different places to meet the usage needs of different places.

[0050] In other implementation scenarios, the cabin 1 can also be configured as a mobile cabin. For example, the cabin 1 can be configured as a vehicle-mounted structure, allowing the pre-washing cabin to be moved and used in different locations within the same area, thereby improving its utilization rate. In this case, the pre-washing cabin is particularly suitable for high-throughput locations such as quarantine stations and coastal ports, as it can greatly improve pre-washing efficiency while ensuring the pre-washing effect.
