Description

Technical Field

[0001] The present invention relates to the field of drying systems, and in particular to a maintenance system and a dehumidification method for high-humidity environments. Background Art

[0002] Cultural relics and ancient books can clearly reveal historical culture, and different cultural relics can reveal different historical cultures. For example, tombs can directly reflect historical culture and customs. Take the Five Helmets Tomb Chamber, for example. Constructed in the late sixth century AD, it belongs to the royal tombs of the late Goguryeo Dynasty. The rich and varied murals within the tomb fully demonstrate the rich artistic heritage of Goguryeo and the rich artistic style of Central Plains culture, drawing on the essence of Taoist and Buddhist religious art from the Eastern Han Dynasty to the Wei and Jin Dynasties. However, despite waterproofing around the tomb chamber, water seepage persists due to a combination of factors, including its stonework and surrounding vegetation. Furthermore, due to its underground location, the large temperature difference between inside and outside causes condensation of moisture, resulting in perennially high humidity levels. At the same time, visitors introduce external particles into the tomb chamber and release carbon dioxide, which affects the tomb's "microenvironment." Without effective control over light intensity and UV intensity, under suitable temperature and humidity conditions, mold and light-induced plant growth can occur. This can further cause the murals within the tomb chamber to discolor, fade, become incomplete, break, and mildew, compromising their integrity and seriously impacting their long-term preservation. Therefore, a drying system is needed in the art to reduce humidity in high-humidity environments like tomb chambers, control the air cleanliness within the tomb chamber, and achieve preventative protection for artifacts in these environments.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0026] In the detailed description that follows, reference may be made to the various drawings that form part of this application and illustrate specific embodiments of the present application. In the drawings, similar reference numerals describe substantially similar components in different figures. Each specific embodiment of the present application is described below in sufficient detail to enable a person of ordinary skill in the art to implement the technical solutions of the present application. It should be understood that other embodiments may be utilized or that structural, logical, or electrical changes may be made to the embodiments of the present application.

[0027] The present application provides a novel high-humidity environment maintenance system that can remove existing condensed water in high-humidity environments (e.g., tombs, underground grottoes, etc.), inhibit the generation of new condensed water, and regulate the humidity within the environment to the optimal state for preserving murals. The system achieves stable dehumidification of high-humidity environments through three stages and regulates the humidity within the environment, thereby ensuring that the murals will not peel or fall off due to sudden changes in the environment, effectively providing preventive protection for the murals. Furthermore, the high-humidity environment maintenance system of the present application can reduce the relative humidity change rate of the high-humidity environment to no more than 10% / hour during dehumidification, thereby preventing damage to the murals due to excessively rapid changes in relative humidity within the environment.

[0028] The technical solution of this application is further described below through specific implementation methods. Those skilled in the art should understand that the following description is only for the purpose of facilitating the understanding of the technical solution of this application and should not be used to limit the scope of protection of this application.

[0029] Figure 1 The following is a schematic diagram of a maintenance system for high-humidity environments according to one embodiment of the present application. The technical solution of this application will be illustrated below using a tomb chamber as an example. As those skilled in the art will appreciate, the application of this application is not limited to tomb chambers. The technical solution of this application can also be applied to other environments or spaces where humidity is significantly affected by external humidity fluctuations and where stable humidity regulation is difficult to achieve.

[0030] As shown in the figure, a maintenance system 100 for a high-humidity environment (hereinafter referred to as the "maintenance system") includes a dry air source 110 and pipelines 120. Dry air source 110 can be located outside the tomb chamber to provide dry air. Pipes 120 are distributed throughout the tomb chamber and connected to dry air source 110. These pipelines can deliver air from the dry air source to various locations within the tomb chamber, creating a slightly positive pressure within the chamber, displacing the air within the chamber and dehumidifying it. In some embodiments, dry air source 110 can also purify the air entering the tomb chamber, ensuring clean air and preventing it from affecting the "microenvironment" within the chamber.

[0031] In some embodiments, the pipes 120 are distributed and laid inside the tomb chamber, which can effectively dehumidify the gas in various places in the tomb chamber. For example: they are evenly spaced on each wall of the tomb chamber or on any wall, or distributed in each corner of the tomb chamber, or evenly laid in the gap between the coffin bed, etc. In some embodiments, the pipes 120 can be PVC pipes. In some embodiments, small holes can be evenly opened on the pipes located in the tomb chamber, and the gas in the pipes can emerge from the small holes, with uniform air discharge and gentle airflow, which helps to protect cultural relics such as murals in the tomb chamber. In some embodiments, a plurality of branches in different directions can be installed on the pipes located in the tomb chamber, which helps the gas in the pipes to fully contact the interior of the tomb chamber and improve the dehydration efficiency of the tomb chamber.

[0032] In some embodiments, pipeline 120 includes multiple outlets with adjustable direction, flow rate, and flow velocity. In some embodiments, the spacing, number, and effective diameter of the outlets in pipeline 120 can be determined based on one or more of the humidity of the gas entering the tomb chamber, the flow rate of the gas entering the tomb chamber, the flow rate of the gas entering the tomb chamber, and the volume of the tomb chamber. In some embodiments, the spacing between the outlets can be 0.05 to 1 meter. In some embodiments, the flow velocity of the gas at the outlets can be 0.1 to 10 m / s.

[0033] In some embodiments, a detection device (eg, a flow meter) may be installed at the location where the pipeline 120 enters the tomb chamber to detect information such as the flow rate and flow velocity of the gas entering the tomb chamber.

[0034] According to one embodiment of the present application, the dry gas source 110 includes an air compressor 101, a filter 102, an activated carbon canister 103, an air tank 104 and a pipeline 105, wherein the air compressor 101 is connected to the filter 102, the activated carbon canister 103 and the air tank 104 in sequence through the pipeline 105, the air compressor 101 is used to compress the air, the filter 102 and the activated carbon canister 103 are used to perform multi-stage filtration on the gas compressed by the air compressor 101 to purify the gas; the air tank 104 is used to store the purified gas and can be connected to the pipeline 120 to output the gas. In some embodiments, the dry gas source 110 may also include an air drying device (not shown in the figure), which can be connected between the air compressor and the activated carbon canister for preliminary drying of the compressed air. In some embodiments, the air drying device may also be provided in the air compressor. In some embodiments, the air drying device may be a cold dryer, a drying membrane, etc.

[0035] In some embodiments, dry air source 110 may further include a housing 106, which may be used to house air compressor 101, filter 102, activated carbon canister 103, air tank 104, pipeline 105, and air drying device, thereby facilitating cleanliness and safety of the system and protecting components such as air compressor 101, filter 102, activated carbon canister 103, air tank 104, and pipeline 105. In some embodiments, filter 102 and activated carbon canister 103 may alternatively be other filtration devices, but the filtration level is required to reach the ppb level.

[0036] In some embodiments, the humidity of the gas provided by the dry gas source needs to be adjusted before entering the tomb chamber to meet the protection requirement of slowly decreasing the humidity of the tomb chamber. According to one embodiment of the present application, the maintenance system 100 may also include an air distribution and humidity control device 160, which can be located outside the tomb chamber, arranged between the dry gas source 110 and the pipeline 120. This device mixes the clean gas provided by the dry gas source into gas with an appropriate humidity, and then inputs it into the tomb chamber through the pipeline 120 to regulate the humidity within the tomb chamber.

[0037] According to one embodiment of the present application, the air distribution and humidity control device 160 includes a humidification branch 162 and an air distribution device 161, wherein the humidification branch is connected to the dry air source and can be used to humidify the gas provided by the dry air source to produce humidified gas. The air distribution device 161 is connected to the dry air source, the humidification branch and the pipeline 120, and can be used to adjust the mixing ratio of the gas provided by the dry air source and the gas provided by the humidification branch to configure gas with appropriate humidity, which is input into the tomb chamber through the pipeline 120.

[0038] In some embodiments, the humidification branch includes an airtight water tank, a humidifying device (e.g., an ultrasonic atomizer), etc. The humidifying device can be disposed in the airtight water tank. When the dry gas source enters the airtight water tank, the humidifying device generates water mist, thereby producing gas with a higher humidity.

[0039] In some embodiments, the gas distribution device can be a control box, which can include a flow control valve (for example, a gas distribution valve), which can adjust the mixing ratio of the humidification branch gas and the dry gas source gas by controlling the on-off or passage size of the humidification branch and / or the dry gas source. In some embodiments, the gas distribution device can also include a flow controller, which can adjust the mixing ratio of the humidification branch gas and the dry gas source gas by controlling the gas flow of the humidification branch and the dry gas source. In some embodiments, the gas distribution and humidity control device 160 can also include a pressure reducing valve (not shown in the figure), which is arranged between the humidification water tank and the dry gas source to reduce the pressure of the gas provided by the dry gas source. In some embodiments, the pressure reducing valve can be located in an airtight water tank.

[0040] In some embodiments, the humidifier 161 can adjust the ratio of the humidified gas to the dry gas according to the desired humidity. In some embodiments, the desired humidity can be determined based on the current humidity of the chamber and a preset humidity change rate. In some embodiments, the desired humidity can be determined based on the current humidity of the chamber, a preset humidity of the chamber, and a preset humidity change rate.

[0041] According to one embodiment of the present application, the air distribution and humidity control device 160 may further include a humidity sensor (not shown) mounted on the outlet pipeline of the air distribution and humidity control device (e.g., between the humidifier 161 and the pipeline 120) to detect the humidity of the humidified gas, thereby precisely controlling the humidity of the gas entering the tomb chamber. In some embodiments, the air distribution valve is controlled using a PID method based on the detected gas humidity, thereby precisely distributing gas of the desired humidity.

[0042] According to one embodiment of the present application, the maintenance system 100 may further include an integrated display and control device 130, which may be installed in the housing 106 and may be used to display the operating status of the maintenance system and control the operation of the maintenance system. According to one embodiment of the present application, the integrated display and control device 130 may also be independently provided to control the operation of the maintenance system or receive and display the operating data of the maintenance system via a wired or wireless connection.

[0043] In some embodiments, the integrated display and control device 130 includes a processor (not shown in the figure), which can be used to control the operation of the dry air source and the air distribution and humidity control device to generate gas with appropriate humidity and deliver it to the tomb chamber. In some embodiments, the integrated display and control device 130 may also include a touch display (not shown in the figure), which can be used to display the operating status of the maintenance system, and can touch input instructions to the processor to control the operation of the maintenance system. In some embodiments, the integrated display and control device 130 may also include other electrical components. For example: the memory can store system operation data, the signal transceiver can receive or send signals, etc. In some embodiments, the integrated display and control device 130 may also include a box 131, which is used to accommodate the various components of the integrated display and control device 130.

[0044] According to one embodiment of the present application, the maintenance system 100 may further include an enclosure structure 140, which is arranged in the tomb chamber and laid close to the murals along the murals to protect the murals and prevent tourists from touching the murals at will and causing damage to the murals; it may also be arranged only in front of each air outlet of the pipeline 120 to guide the gas transported by the pipeline 120 to the surface of the tomb chamber, ensuring that the transported gas flows evenly and is distributed in the tomb chamber, so that the gas transported into the tomb chamber can form a circulation and a slightly positive pressure in the tomb chamber from bottom to top, thereby replacing the original high-humidity gas in the tomb chamber to the outside of the tomb chamber, gradually reducing the humidity of the air in the tomb chamber, and achieving the purpose of uniform and stable dehumidification of the tomb chamber. According to one embodiment of the present application, the enclosure structure 140 can be a glass enclosure structure, which will not affect the tourists' visit and can protect the murals. In some embodiments, the enclosure structure 140 can use high-transmittance low-reflection laminated glass, which is conducive to tourists being able to clearly view the murals, and when the glass breaks, it will not cause damage to the murals or tourists.

[0045] According to one embodiment of the present application, the maintenance system 100 may also include a lighting system, which can be used for lighting inside the tomb. The lighting system includes one or more lighting devices 151 and one or more sensing devices 152. The one or more lighting devices 151 are respectively arranged at different positions inside the tomb (for example, the center of the tomb, or each corner of the tomb, etc.). The sensing device 152 can be arranged at the door of the tomb, and can sense someone entering the tomb and upload it to the integrated display and control device 130, and then the integrated display and control device 130 can control the lighting device to illuminate, so as to facilitate maintenance by staff or visitors; it can also sense someone leaving the tomb and upload it to the integrated display and control device 130, and then the integrated display and control device 130 can control the lighting device to turn off, which can effectively reduce the damage of light to cultural relics such as murals in the tomb, and at the same time reduce the probability of mold, moss and other pollution in the tomb due to the lighting system, and effectively protect the murals. In some embodiments, the sensing device can also be arranged near the corresponding lighting device.

[0046] According to one embodiment of the present application, the lighting device 151 may be an LED lamp, energy-saving lamp, or the like. Preferably, a cold light source is used to minimize the impact of light on the artifacts within the tomb chamber. In some embodiments, the sensing device 152 may be a human proximity sensor, remote sensor, heat sensor, or the like. In some embodiments, the lighting system may also include other control devices, such as switches and remote controls, that can directly control the state of the lighting device.

[0047] According to one embodiment of the present application, the maintenance system 100 may further include a terminal detection device, which may be used to detect environmental parameters inside and outside the tomb and feed them back to the integrated display and control device. According to one embodiment of the present application, the terminal detection device may include one or more temperature and humidity sensors 171, which may be set in the tomb, in the corridor, and / or in the pipeline 120. Figure 1 In the embodiment, the terminal detection device may include 5 temperature and humidity sensors 171, of which 3 temperature and humidity sensors are evenly distributed inside the tomb chamber to monitor the temperature and humidity inside the tomb chamber in real time, 1 temperature and humidity sensor is set in the outer section of the tomb chamber of the pipe 120 to monitor the temperature and humidity in the pipe 120 in real time, and 1 temperature and humidity sensor is set in the corridor to monitor the temperature and humidity in the corridor in real time, and upload all collected temperature and humidity parameters to the integrated display and control device to facilitate real-time adjustment of the air distribution humidity of the air distribution and humidity control system, and accurately adjust the humidity of the gas in the tomb chamber. In some embodiments, there may be other numbers of temperature and humidity sensors. In some embodiments, the temperature and humidity sensors preferably have high tolerance to high humidity environments to prevent inaccurate measurements caused by the humidity of the tomb chamber.

[0048] According to one embodiment of the present application, the terminal detection device may further include one or more light intensity sensors 172, which are arranged inside the tomb chamber and can perform real-time detection of the light inside the tomb chamber, and upload the detection results to the integrated display and control device, which can adjust the start and stop of the maintenance system according to the detection results. According to one embodiment of the present application, the terminal detection device may further include one or more carbon dioxide sensors 173, which are arranged inside the tomb chamber and can perform real-time detection of the carbon dioxide concentration in the tomb chamber, and upload the detection results to the integrated display and control device, which can adjust the start and stop of the maintenance system according to the detection results, replace the gas in the tomb chamber, reduce the carbon dioxide concentration, and prevent damage to the murals due to excessive carbon dioxide concentration.

[0049] According to one embodiment of the present application, the maintenance system 100 may also include a return air system (not shown). When the integrated display and control device receives information from the carbon dioxide sensor detecting that the carbon dioxide concentration in the tomb chamber is too high, it controls the return air system to extract the gas from the tomb chamber and replace the gas inside. In some embodiments, while the return air system is extracting the gas from the tomb chamber, the integrated display and control device may also control the dry air source and the gas distribution control device to deliver gas with the same or slightly higher humidity into the tomb chamber to ensure that the relative humidity within the tomb chamber remains stable.

[0050] Figure 2 The figure is a dehumidification flow chart for a high humidity environment according to one embodiment of the present application.

[0051] As shown in the figure, whether there is condensed water in the high humidity environment is detected in step 210. Since the humidity in the high humidity environment is relatively high, when dehumidifying it, it is necessary to judge the humidity state in the environment in advance.

[0052] In step 220, when condensed water is detected in the high humidity environment, gas at a first humidity is introduced into the high humidity environment. In some embodiments, the first humidity is close to or slightly lower than the humidity in the high humidity environment. In some embodiments, the first humidity can be 85%-95%. In some embodiments, after the condensed water in the high humidity environment is removed, the introduction of gas at the first humidity into the environment can be stopped. In some embodiments, when the introduction of gas at the first humidity into the high humidity environment is paused, step 230 can be performed. In some embodiments, when the absence of condensed water in the high humidity environment is detected, the following steps can be performed directly.

[0053] In step 230, it is detected whether there is water seepage in the high humidity environment. When it is determined that there is no condensed water in the environment or the condensed water in the environment has been removed, it is necessary to determine whether water outside the environment will seep into the environment in order to maintain the humidity in the high humidity environment.

[0054] In step 240, when the presence of permeated water is detected in the high humidity environment, gas at a second humidity is introduced into the high humidity environment. In some embodiments, the second humidity is lower than the first humidity. In some embodiments, the second humidity may be between 80% and 90%. In some embodiments, when no permeated water is present in the high humidity environment, the introduction of gas at the second humidity into the high humidity environment may be suspended. In some embodiments, when the introduction of gas at the second humidity into the high humidity environment is suspended, step 250 may be performed. In some embodiments, when no permeated water is detected in the high humidity environment, the following steps may be performed directly.

[0055] In step 250, the humidity in the high humidity environment is detected to see if it exceeds a preset threshold. When there is no condensed water or seepage water in the high humidity environment, the humidity environment in the tomb chamber needs to be maintained and the humidity in the tomb chamber needs to be detected in real time to protect the murals or collections.

[0056] In step 260, when the humidity in the high humidity environment is detected to exceed a preset threshold, gas at a third humidity is introduced into the high humidity environment. For example, when the humidity in the environment is detected to be above the preset threshold, gas at a humidity slightly below the preset threshold needs to be introduced. When the humidity in the environment is detected to be below the preset threshold, gas at a humidity slightly above the preset threshold needs to be introduced to maintain a stable humidity in the high humidity environment. In some embodiments, the third humidity is lower than the second humidity. In some embodiments, the third humidity can be determined based on the current humidity detected in the high humidity environment and a preset humidity change rate. In some embodiments, the third humidity can be determined based on the current humidity in the high humidity environment, a preset threshold, and a preset humidity change rate. In some embodiments, the third humidity can be between 50% and 60%. In some embodiments, when the humidity in the high humidity environment is adjusted, the relative humidity in the high humidity environment changes by at least no more than 10% per hour.

[0057] In step 270 , when the humidity in the high humidity environment is detected to be within a preset threshold range, the delivery of gas into the high humidity environment is stopped.

[0058] When using the maintenance system of this application, parameters such as the humidity and carbon dioxide content of the tomb chamber can be set in advance through the integrated display and control device. When the settings are completed, press the start button. Based on the data collected by the temperature and humidity sensors inside and outside the high-humidity environment, and the required intake humidity, as well as the expected values of parameters such as the humidity and carbon dioxide in the high-humidity environment, the system will automatically start to regulate the humidity and carbon dioxide concentration in the high-humidity environment. The original humid air in the high-humidity environment is replaced outside the high-humidity environment in a micro-positive pressure manner, and the humidity of the high-humidity environment is slowly reduced to the expected value to prevent rapid drying from damaging the murals or collections. When the humidity and carbon dioxide concentration in the high-humidity environment are reduced to the set value, the system automatically stops running and enters standby mode. The terminal detection device continuously detects the various gas parameters in the high-humidity environment. When the humidity, carbon dioxide and other parameters exceed the set value upper limit, the system starts again for regulation. This cycle controls the "microenvironment" of the high-humidity environment in a relatively stable state. The purpose of dehydrating and dehumidifying the high-humidity environment is achieved, and then the murals or collections are preventively protected, preventing the murals or collections from being damaged due to excessive humidity in the high-humidity environment or too fast dehumidification process. It can provide support for the preventive protection of murals in high-humidity environments to a certain extent, and promote the smooth progress of mural protection and restoration work in high-humidity environments.

[0059] The above embodiments are only used to illustrate the present invention, and are not intended to limit the present invention. Ordinary technicians in the relevant technical field can make various changes and modifications without departing from the scope of the present invention. Therefore, all equivalent technical solutions should also fall within the scope of the present invention.
