Description

Technical Field

[0001] This invention relates to operating rooms, and more specifically to a low-carbon clean operating room. Background Technology

[0002] In hospital construction, clean operating rooms are among the most important departments and a key factor in ensuring adequate medical care. Clean operating rooms have strict standards for parameters such as air cleanliness, bacterial count, temperature, humidity, illumination, noise, and pressure differential. Traditional clean operating rooms (such as...) Figure 1 As shown in the diagram, the circulating fan unit 2' provides standard-compliant circulating air through multi-stage filtration via the circulating fan unit duct 2'-1 system. Simultaneously, the fresh air unit 3' provides standard-compliant fresh air through multi-stage filtration via the fresh air unit duct 3'-1 system. Then, the standard-compliant circulating air and fresh air enter the clean operating room through the supply air ceiling 1'. Traditional clean operating rooms are large in size, resulting in high construction costs, significant construction difficulty, and long construction periods. Furthermore, the complex and interwoven duct systems of the circulating fan unit and fresh air unit make adjustment difficult. Over time, the standard-compliant circulating air and fresh air can become contaminated by viruses, bacteria, and other microorganisms remaining in the ducts, leading to a decrease in air filtration and purification efficiency. Summary of the Invention

[0003] In view of this, it is necessary to propose a low-carbon clean operating room that can effectively reduce construction costs, construction difficulty, shorten construction cycle, save construction space, and facilitate maintenance while meeting the standards for clean operating rooms.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A low-carbon clean operating room includes a main operating room space, an air supply ceiling above the main operating room space, at least one air conditioner and a fresh air unit connected to the air supply ceiling, a return air vent located near the lower end of the inner wall of the main operating room space, and a low-resistance high-efficiency filtration module. The low-resistance high-efficiency filtration module includes a frame, a corona electrode arranged front and back in the frame along the airflow direction, an electrostatic fiber layer with charged charge, an electret electrode closely attached to the electrostatic fiber layer, and a ground electrode. When energized, the corona electrode generates a corona discharge, causing dust particles in the flowing air to become negatively charged. When energized, the electret electrode continuously charges the electrostatic fiber layer with charged charge, keeping the electrostatic fiber layer continuously positively charged. The electrostatic fiber layer filters the air through physical interception and electrostatic adsorption. The low-resistance high-efficiency filtration module is mounted on the air supply ceiling via a frame.

[0006] Preferably, low-resistance, high-efficiency filter modules are installed at both ends of the air supply ceiling.

[0007] More preferably, the low-resistance high-efficiency filter module is installed on at least one air conditioner, fresh air unit, and return air vent.

[0008] Furthermore, the low-resistance high-efficiency filtration module also includes a disinfection and purification module, which is located on the side of the frame near the electrostatic fiber layer.

[0009] Furthermore, it also includes a disinfection and purification module, which is located on the side of the frame near the electrostatic fiber layer and is used to disinfect and purify the filtered air.

[0010] Specifically, the disinfection and purification module includes a shell that extends through both sides. One side of the shell that extends through is positioned opposite to the electrostatic fiber layer and is connected to the frame. At least one inner wall of the shell is provided with an ultraviolet lamp. The inner walls of the shell together form an air disinfection and purification space.

[0011] Furthermore, the disinfection and purification module also includes a plasma generator, which is installed on a different inner wall than the ultraviolet lamp.

[0012] Furthermore, the disinfection module also includes a photocatalytic mesh, which is disposed at the through-hole of the housing near the electrostatic fiber layer.

[0013] Furthermore, the disinfection and purification module also includes a protective net, which is disposed at the opening on the side of the housing away from the through-hole of the electrostatic fiber layer.

[0014] Preferably, the at least one air conditioner is embedded in the interior wall of the main operating room space.

[0015] Furthermore, a control module is also provided, as well as temperature sensors, humidity sensors, and differential pressure sensors electrically connected to the control module. The control module detects and controls the temperature, humidity, differential pressure, and equipment operation of the main space of the operating room through the temperature sensors, humidity sensors, and differential pressure sensors.

[0016] The beneficial effects of this invention's low-carbon clean operating room are as follows:

[0017] 1) This invention significantly reduces fan power while maintaining a stable and high filtration level that meets the standards for clean operating rooms through a low-resistance, high-efficiency filtration module.

[0018] 2) By replacing the traditional bulky equipment and complex, interwoven filter piping system with low-resistance, high-efficiency filter modules installed at the air supply ceiling, construction costs, construction difficulty and construction cycle can be effectively reduced.

[0019] 3) Since it does not require large equipment and a complex, interwoven filtration piping system, the equipment layer can be eliminated, thus effectively saving construction space;

[0020] 4) The overall installation is quick and easy, and it is also easy to maintain and replace later;

[0021] 5) While achieving a Class 100 medical purification environment, it also achieves the dual carbon goals of green environmental protection and energy conservation. Attached Figure Description

Therefore, the use of “first,” “second,” “third,” and “fourth” to designate a feature may explicitly or implicitly include one or more of that feature.

[0034] Example 1

[0035] like Figure 2 As shown, a low-carbon clean operating room includes a main operating room space, an air supply ceiling 1 installed above the main operating room space, at least one air conditioner 2 and a fresh air unit 3 connected to the air supply ceiling 1, a return air vent 7 installed on the inner wall of the main operating room space near the lower end, and a low-resistance high-efficiency filter module 4.

[0036] Among them, such as Figure 3 As shown, the low-resistance high-efficiency filter module 4 includes a frame 41, a corona electrode 42 arranged front to back in the frame 41 along the airflow direction, an electrostatic fiber layer 43 with chargeable charge, an electret electrode 44 closely attached to the electrostatic fiber layer 43, and a ground electrode 45. A power supply box 47 is provided at one end of the frame. The power supply box 47 is electrically connected to the corona electrode 42, the electret electrode 44, and the ground electrode 45. The power supply box 47 supplies power to the corona electrode 42 and the electret electrode 44. Of course, the corona electrode and the electret electrode can also be directly powered by an external power source.

[0037] The corona electrode 42 is composed of several horizontally spaced wires. The corona electrode 42 is powered by the power supply box 47. The corona electrode can generate corona to make the dust particles in the flowing air negatively charged without a very high voltage. Of course, in order to make the dust particles in the air negatively charged quickly and efficiently, the corona electrode is preferably powered by a voltage of 8000-10000V.

[0038] When powered by the power supply box 47, the electret electrode 44 does not need a very high voltage to continuously charge the electrostatic fiber layer 43 with positive charge. Of course, in order to charge the electrostatic fiber layer with positive charge quickly and efficiently, the electret electrode preferably uses a voltage of 4000V.

[0039] The chargeable electrostatic fiber layer 43 is preferably an electrostatic fiber cotton that can carry charge. Of course, the present invention is not limited to electrostatic fiber cotton that can carry charge. Other electrostatic fiber materials that can carry charge are also included in the embodiment of the chargeable electrostatic fiber layer of the present invention. The chargeable electrostatic fiber layer 43 filters the air through physical interception and electrostatic adsorption.

[0040] For the low-resistance, high-efficiency filter module 4, such as Figure 3 As shown, the electret electrode 44 is closely attached to the charged electrostatic fiber layer 43 facing the corona electrode 42, and the ground electrode 45 of the low-resistivity high-efficiency filter module 4 is located between the corona electrode 42 and the charged electrostatic fiber layer 43 and close to the corona electrode 42, making the structure of the low-resistivity high-efficiency filter module more compact and its stability and safety higher. Preferably, the corona electrode 42 and the ground electrode 45 are integrated into an inner frame and are integrally fitted into the frame 41, making the low-resistivity high-efficiency filter module 4 more integrated and easier to install and maintain.

[0041] The low-resistance, high-efficiency filter module 4 is mounted on the air supply ceiling 1 via frame 41.

[0042] The air conditioner 2 in the low-carbon clean operating room of this invention consists of two or more ordinary vertical air conditioners, one of which is a refrigeration cabinet and the other is a heating cabinet. During the summer cooling process, the refrigeration cabinet cools and dehumidifies to control humidity, while the heating cabinet controls temperature. During the transitional season, the refrigeration cabinet controls temperature and humidity, while the heating cabinet activates ventilation mode. During the winter, the refrigeration cabinet controls temperature, the humidifier 6 controls humidity, and the heating cabinet activates ventilation mode.

[0043] Better, such as Figure 3 As shown, in order to better filter the air, low-resistance high-efficiency filter modules 4 are installed at both ends of the air supply ceiling 1.

[0044] Better, such as Figure 4 As shown, in order to provide cleaner filtered air, low-resistance high-efficiency filter modules 4 are installed on at least one air conditioner 2, fresh air unit 3 and return air vent 7 respectively.

[0045] The working principle of this invention's low-carbon clean operating room is as follows: Power is supplied to the clean operating room. At least one air conditioner provides indoor circulating air through the supply and return air vents. Simultaneously, a fresh air unit provides fresh air to the room through the supply ceiling. When the mixed indoor circulating air and fresh air flow through the supply ceiling, the corona electrode of the low-resistance high-efficiency filter module generates a corona through a voltage of 8000-10000V. Simultaneously, the electret electrode continuously supplies power to the charged electrostatic fiber layer with a voltage of approximately 4000V, keeping it continuously positively charged. When air flows through the corona section, the dust particles in the air become negatively charged. These negatively charged dust particles pass through the charged electrostatic fiber layer. Particles larger than 0.5μm are mainly filtered by the physical interception of the charged electrostatic fiber layer, while particles smaller than 0.5μm, such as 0.3μm and 0.1μm, are filtered by the positive electrostatic adsorption of the charged electrostatic fiber layer. The filtered clean air enters the main space of the operating room, and this cycle continues, continuously and stably providing the clean operating room with air that meets the standard requirements.

[0046] The parameter test comparison and main component cost comparison of the low-carbon clean operating room of this invention and the traditional Class 100 operating room are shown in Tables 1 and 2 below:

[0047] (Table 1)

[0048]

[0049] (Table 2)

[0050] Main part This invention relates to a low-carbon clean operating room (45m²). Traditional Class 100 operating room (45m2) Ductwork section 20,000 yuan 45,000 yuan Filtering section 63,000 yuan 6000 yuan Equipment section 32,000 yuan 100,000 yuan control system 10,000 yuan 20,000 yuan Water pipes and refrigerant pipes 20,000 yuan 50,000 yuan Main part cost 145,000 yuan 221,000 yuan

[0051] The comparison of various parameters and main component costs between the low-carbon clean operating room of the present invention and the traditional clean operating room shows that the air conditioning system of the low-carbon clean operating room of the present invention can save up to 55% energy and reduce the cost of main components by 34% compared with the traditional clean operating room air conditioning system.

[0052] The advantages of this invention's low-carbon clean operating room compared to traditional clean operating rooms are as follows:

[0053] 1) This invention significantly reduces fan power while maintaining a stable and high filtration level that meets the standards for clean operating rooms through a low-resistance, high-efficiency filtration module.

[0054] 2) By replacing the traditional bulky equipment and complex, interwoven filter piping system with low-resistance, high-efficiency filter modules installed at the air supply ceiling, construction costs, construction difficulty and construction cycle can be effectively reduced.

[0055] 3) Since it does not require large equipment and a complex, interwoven filtration piping system, the equipment layer can be eliminated, thus effectively saving construction space;

[0056] 4) The overall installation is quick and easy, and it is also easy to maintain and replace later;

[0057] 5) While achieving a Class 100 medical purification environment, it also achieves the dual carbon goals of green environmental protection and energy conservation.

[0058] Another embodiment of a low-resistance, high-efficiency filtration module for a low-carbon clean operating room according to the present invention.

[0059] like Figure 5 As shown, the low-resistance high-efficiency filtration module 4 also includes a disinfection and purification module 8, which is located on the side of the frame 41 near the electrostatic fiber layer 43.

[0060] Specifically, such as Figure 6-7 As shown, the disinfection and purification module 8 includes a shell 81 extending through both sides. One side of the shell 81 is positioned opposite to the electrostatic fiber layer 83 and communicates with the frame 41. At least one inner wall of the shell 81 is provided with an ultraviolet lamp 82. The inner walls of the shell 81 together form an air disinfection and purification space. Preferably, as shown... Figure 6 As shown, the ultraviolet lamps 82 are distributed on one inner wall and the upper and lower inner walls of the housing 81, so that the air disinfection and purification space is evenly irradiated with ultraviolet light. Preferably, as shown... Figure 6 As shown, the housing 81 of the disinfection and purification module 8 also houses an ultraviolet lamp driver 86, which ensures more stable and reliable operation of the ultraviolet lamp. The ultraviolet lamp can eliminate and purify particles filtered by the electrostatic fiber layer and viruses and bacteria flowing through the purified space, thereby preventing viruses and bacteria from spreading and spreading indoors with air circulation, reducing the quality of purified air, and ensuring safer replacement and installation in the future.

[0061] Furthermore, such as Figure 6 As shown, the disinfection and purification module 8 also includes a plasma generator 83, which is disposed on a different inner wall from the ultraviolet lamp 82. Preferably, as shown... Figure 6 The plasma generator 83 shown is mounted on the inner wall opposite the ultraviolet lamp, ensuring that plasma is evenly distributed throughout the disinfection and purification space. The plasma generator effectively disinfects and sterilizes, guaranteeing the quality of the purified air and making future replacements and installations safer.

[0062] Furthermore, such as Figure 7 As shown, the disinfection and purification module 8 also includes a photocatalytic mesh 84. The photocatalytic mesh 84 is disposed at the through-hole of the shell 81 near the electrostatic fiber layer 43. The air entering the disinfection and purification module first passes through the photocatalytic mesh 84. Under the illumination of the ultraviolet lamp, the photocatalytic mesh 84 continuously ensures that the activation medium is not depleted and can be continuously regenerated and used. It can effectively remove harmful gases and odors in the air flowing through it, and also has a bactericidal effect.

[0063] Furthermore, such as Figure 7 As shown, the disinfection and purification module 8 also includes a protective net 85, which is located at the opening on the side of the housing 81 away from the electrostatic fiber layer 43, and can play a role in safety protection.

[0064] Another embodiment of the low-resistance, high-efficiency filtration module of the present invention, with a disinfection and purification module, not only provides air filtration with low resistance, high efficiency, stable filtration performance, and no ozone generation, but also has disinfection and purification functions. This not only achieves a Class 100 medical purification environment but also realizes the dual carbon goals of green environmental protection and energy conservation.

[0065] Example 2

[0066] This embodiment is an improvement on the air conditioner based on Embodiment 1.

[0067] like Figure 4 As shown, the air conditioner 2 is embedded in the interior wall of the main operating room space, which can save construction space more effectively.

[0068] Example 3

[0069] This embodiment adds components such as a control module to the basis of embodiment 1 or / and 2.

[0070] like Figure 2 As shown, the low-carbon clean operating room of this invention also includes a control module 5, and a temperature sensor, a humidity sensor, and a differential pressure sensor (not shown) electrically connected to the control module 5. The temperature sensor and humidity sensor can be installed in the main space of the operating room, and the differential pressure sensor can be installed inside the operating room and at the low-resistivity high-efficiency filter module and the air conditioner or fresh air unit. The control module 5 detects and controls the temperature, humidity, and differential pressure of the main space of the operating room through the temperature sensor, humidity sensor, and differential pressure sensor to ensure precise control of the temperature, humidity, and differential pressure of the low-carbon clean operating room, thereby realizing a constant temperature and humidity low-carbon clean operating room. Moreover, the control module 5 detects the differential pressure across the low-resistivity high-efficiency filter module and the air conditioner or fresh air unit through the differential pressure sensor to determine whether the low-resistivity high-efficiency filter module is blocked and the operating status of the air conditioner and fresh air unit.

[0071] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention. Therefore, the scope of protection of this patent should be determined by the appended claims.
