Description

Technical Field

[0001] This invention relates to the field of compressed air humidification technology, specifically to a high back pressure compressed air humidification device, humidification control method, and equipment. Background Technology

[0002] After air is compressed by a compressor, the partial pressure of water vapor inside it increases significantly. During subsequent transportation, if the ambient temperature drops below the dew point temperature of the compressed air, the water vapor dissolved in the air will condense into liquid water. Since most compressed air applications do not allow the presence of liquid water, air compressors are usually equipped with dryers or freeze dryers to remove excess moisture from the compressed air and ensure it is in a low-humidity, dry state. However, in certain specific processes, compressed air needs to contain a specific concentration of water vapor. In these cases, humidification is required to increase the water vapor content in the compressed air and precisely adjust its humidity to the range required by the process. These humidity-sensitive processes are often under high back pressure conditions. Under these conditions, the humidification capacity, flow velocity, and other physical properties of the compressed air differ significantly from those under conventional low-pressure conditions.

[0003] Existing compressed air humidification devices mostly have a fixed air distribution structure, and the air distribution parameters cannot be adjusted. This leads to uneven air distribution during humidification, easily causing localized oversaturation in some areas while other areas are underhumidified, resulting in poor humidification uniformity. Furthermore, high back pressure alters the size and diffusion range of the spray water atomized particles. Since the number of spray heads in existing humidification devices is fixed, the range of spray water volume adjustment is limited, making it unable to adapt to the diverse humidification needs under high back pressure conditions.

[0004] In summary, existing compressed air humidification devices suffer from poor humidification uniformity and limited flow rate adjustment due to their air distribution structure and spray head design being unable to adapt to the changes in compressed air characteristics under high back pressure conditions. As a result, they are unable to meet the requirements of the process flow for compressed air humidification effect under high back pressure conditions. Summary of the Invention

[0005] In view of this, the present invention provides a high back pressure compressed air humidification device, humidification control method and equipment to solve the problems that existing compressed air humidification devices cannot adapt to the changes in the characteristics of compressed air under high back pressure conditions, have poor humidification uniformity and limited flow rate adjustment, and are difficult to meet the requirements of the process flow for compressed air humidification effect under high back pressure conditions.

[0006] In a first aspect, the present invention provides a high back pressure compressed air humidification device, which includes a humidification tank, multiple sensors and a control system. The humidification tank includes an adjustable air distribution plate and a spray system, and the multiple sensors are installed inside and outside the humidification tank. The control system is used to determine the target spray water volume and target porosity based on data collected by multiple sensors; An adjustable air distribution plate is installed at a physical height above the inlet of the humidification tank to rectify the compressed air inside the humidification tank based on the target porosity. The spray system is used to spray water mist according to the target spray volume to humidify the rectified compressed air.

[0007] This invention utilizes a humidification tank to provide a stable humidification space for high-back-pressure compressed air and spray water mist. The control system uses data collected in real time by multiple sensors to determine the target spray water volume and target porosity. This allows an adjustable air distributor in the humidification tank to distribute air according to the target porosity, significantly improving humidification uniformity. The compressed air, rectified by the air distributor, forms a uniform upward laminar flow, exchanging heat and moisture with the water mist sprayed by the spray system according to the target spray water volume, thus achieving humidification of the compressed air. By using multiple sensors to monitor humidification environment parameters in real time from all angles, the target porosity during air distributor rectification and the target spray water volume during spray system humidification can be accurately calculated and adjusted. Compared to the fixed design of air distribution structure and spray water volume in existing humidification devices, this invention ensures uniform and precise humidification of compressed air under high back-pressure conditions, meeting the stable humidity requirements of the process flow and significantly improving the applicability and flexibility of the device under complex operating conditions.

[0008] In one alternative embodiment, the adjustable air distribution plate includes a double-layer screen plate; The control system is also used to control the relative rotation of the double-layer sieve plates so that the porosity of the adjustable air distribution plate reaches the target porosity.

[0009] This embodiment ensures that compressed air forms a uniform upward laminar flow after passing through the air distribution plate by adjusting the porosity of the air distribution plate, thereby improving the humidification uniformity.

[0010] In one alternative implementation, the multiple sensors include a humidity sensor and a hot-wire anemometer; A humidity sensor is installed at the outlet of the humidification tank to collect the relative humidity of the outlet air; A hot-wire anemometer is used to collect wind speeds at multiple points on an adjustable air distribution plate.

[0011] This embodiment continuously collects relative humidity and wind speed through multiple sensors, providing a data basis for dynamically correcting porosity and spray water volume.

[0012] In one alternative implementation, the spray system includes multiple nozzles; The control system is also used to combine multiple nozzles to achieve the target spray volume.

[0013] This embodiment uses a combination of multiple nozzles to ensure that the spray water mist is evenly distributed across the cross-section of the humidification tank under high back pressure conditions, providing uniform contact conditions for sufficient heat and moisture exchange between compressed air and water mist.

[0014] In a second aspect, the present invention provides a humidification control method, applied to a high back pressure compressed air humidification device of the first aspect or any corresponding embodiment thereof, the method comprising: Acquire data from multiple sensors; Based on data collected by multiple sensors, the target porosity and target spray water volume are determined; Based on the target porosity and target spray water volume, the compressed air inside the humidification tank is humidified.

[0015] This invention acquires data from multiple sensors to accurately calculate and adjust the target porosity during air distribution plate rectification and the target spray water volume during spray system humidification. Compared to relying on fixed empirical formulas, it can dynamically output target porosity and target spray water volume that are adapted to high back pressure conditions. This ensures that the humidification effect of compressed air is uniform and accurate under high back pressure conditions, meeting the process flow's requirements for stable compressed air humidity.

[0016] In one alternative implementation, the data collected by multiple sensors includes wind speeds at multiple points on the adjustable wind distribution panel. Before determining the target porosity and target spray water volume based on data collected from multiple sensors, the method further includes: For the wind speed at each point of the adjustable air distribution panel, determine the wind speed standard deviation between the wind speed at that point and the wind speed at every other point. When the root mean square deviation of any wind speed at a given location exceeds a preset value, the target porosity of the adjustable air distribution plate is determined.

[0017] This embodiment determines whether to adjust the porosity based on the wind speed at multiple points on the air distribution plate, which helps to achieve uniform air distribution.

[0018] In one alternative implementation, the data collected by the multiple sensors also includes the relative humidity of the outlet air of the humidification tank; The target spray water volume is determined by the following formula:

[0019] In the formula, Q Indicates the target spray water volume; Indicates the current spray water volume; and Indicates the adjustment factor; RH This indicates the relative humidity of the outlet air.

[0020] This embodiment combines theoretical calculations with actual feedback to ensure precise control of the spray water volume, which not only improves humidification efficiency but also effectively reduces the outflow of liquid water, further optimizing the humidification effect.

[0021] In one alternative implementation, the target porosity is determined by the following formula:

[0022] In the formula, Indicates the target porosity; v This represents the average wind speed at multiple points on the adjustable air distribution panel; Indicates the maximum airflow velocity; and This indicates the maximum and minimum porosity.

[0023] In one alternative implementation, the method further includes: Continuously obtain the relative humidity of the outlet air of the humidification tank; Stop humidifying when the relative humidity reaches saturation.

[0024] This embodiment continuously monitors the relative humidity at the outlet and stops humidification when the air reaches saturation, ensuring that the humidity meets the standard while avoiding the risk of liquid water under high back pressure conditions.

[0025] Thirdly, the present invention provides a computer device, comprising: a memory and a processor, wherein the memory and the processor are communicatively connected to each other, the memory stores computer instructions, and the processor executes the computer instructions to perform the humidification control method of the second aspect or any corresponding embodiment described above.

Detailed Implementation

[0029] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] It is understood that before using the technical solutions disclosed in the various embodiments of the present invention, users should be informed of the types, scope of use, and usage scenarios of the personal information involved in the present invention and their authorization should be obtained in accordance with relevant laws and regulations through appropriate means.

[0031] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0032] In certain specific processes, compressed air needs to contain a specific concentration of water vapor. Humidification is then necessary to increase the water vapor content and precisely adjust the humidity to the required range. These humidity-sensitive processes often operate under high back pressure. Existing compressed air humidification devices suffer from poor humidification uniformity and limited flow rate adjustment due to their air distribution structure and spray head design being unable to adapt to the changing characteristics of compressed air under high back pressure conditions. This makes it difficult to meet the humidification requirements of processes under high back pressure. This invention uses multiple sensors to monitor humidification environment parameters in real time, controlling the system to accurately calculate and adjust the target porosity of the air distribution plate during rectification and the target spray water volume during humidification. Compared to the fixed design of the air distribution structure and spray water volume in existing humidification devices, this invention ensures uniform and precise humidification of compressed air under high back pressure conditions, meeting the stable humidity requirements of the process.

[0033] This embodiment provides a high back pressure compressed air humidification device, such as... Figure 1 As shown, the device includes a humidification tank, multiple sensors, and a control system. Figure 1 (Not shown) The humidification tank includes an adjustable air distribution plate and a spray system. Multiple sensors are installed inside and outside the humidification tank. A control system is used to determine the target spray water volume and target porosity based on data collected by multiple sensors. The adjustable air distribution plate is installed at a physical height above the inlet of the humidification tank and is used to rectify the compressed air inside the humidification tank based on the target porosity. The spray system is used to spray water mist according to the target spray water volume to humidify the rectified compressed air.

[0034] Specifically, Figure 2 This is a schematic diagram of a humidification tank according to an embodiment of the present invention, as shown below. Figure 2 As shown, the main body of the humidifier tank is a cylindrical structure with an inner diameter of 850mm, and both ends are elliptical caps, forming a closed vertical container. This is the core area where high-back-pressure compressed air and sprayed water mist exchange heat and moisture to achieve humidification. Compressed air enters the tank through a side inlet at the bottom, first flowing towards an adjustable air distributor slightly higher than the inlet, and then entering the internal space after being rectified by the air distributor. Subsequently, the sprayed water mist is emitted from the spray system inside the humidifier tank. Figure 2(Not shown) The humidified air is ejected and comes into counter-current contact with the rectified compressed air flowing upward below, resulting in sufficient heat and moisture exchange. Finally, the humidified air flows out from the upper outlet. In the above humidification process, existing humidification devices, due to their fixed air distribution structure and spray water volume design, cannot dynamically adapt to high back pressure conditions. Therefore, this embodiment of the invention arranges multiple sensors collaboratively inside and outside the humidification tank to monitor the humidification environment parameters in real time from all angles. Based on these collected real-time data, the control system accurately calculates and adjusts the target porosity during air distribution rectification and the target spray water volume during humidification by the spray system, thereby ensuring uniform and precise humidification of compressed air under high back pressure conditions, meeting the process flow's requirements for stable compressed air humidity.

[0035] Optionally, the humidifier tank is also equipped with temperature and humidity sensors and pressure sensors at its inlet and outlet, and a compressed air mass flow meter is also installed at the inlet. The spray system inlet is equipped with water volume, water temperature, and pressure sensors, as well as a regulating valve.

[0036] In one alternative embodiment, the adjustable air distribution plate includes a double-layer sieve plate; the control system is also used to control the double-layer sieve plate to rotate relative to each other so that the porosity of the adjustable air distribution plate reaches the target porosity.

[0037] Specifically, the adjustable air distribution plate is composed of two layers of sieve plates with the same specifications and porosity stacked on top of each other. Figure 3 This is a schematic diagram of an adjustable air distribution plate according to an embodiment of the present invention, as shown below. Figure 3 As shown, the sieve plate is made of 304L stainless steel, balancing structural strength and corrosion resistance under high back pressure conditions. Each sieve plate is 8mm thick, with 10mm diameter through-holes. The centers of all through-holes are arranged in a regular square matrix to ensure uniform airflow path distribution. The initial porosity (the ratio of the total area of ​​the through-holes to the total area of ​​the sieve plate) of each sieve plate is 80%. Porosity is a core indicator for measuring the airflow capacity of the air distribution plate, specifically referring to the percentage of the total area of ​​all through-holes on the air distribution plate to the overall effective flow area of ​​the air distribution plate (i.e., the area covering the cross-section of the humidification tank). Higher porosity results in lower resistance to airflow through the air distribution plate and allows for higher suitable air velocities; conversely, lower porosity leads to greater resistance and lower suitable velocities.

[0038] When the through holes of the upper and lower sieve plates are perfectly aligned (100% overlap), the overall porosity of the air distribution plate is consistent with that of a single sieve plate, reaching a maximum of 80%. As the control system drives one layer of sieve plates to rotate around the central axis, the overlapping area of ​​the through holes of the two sieve plates gradually decreases. Some through holes are blocked by the solid area of ​​the other sieve plate, thus reducing the total area of ​​effectively flowing through holes and consequently decreasing the porosity. When the overlapping area of ​​the through holes of the two sieve plates is minimized (only 50% of the area of ​​a single sieve plate), the porosity of the air distribution plate drops to a minimum of 40%. This achieves continuous and smooth adjustment of the porosity within the range of 40%-80%. By adjusting the porosity of the air distribution plate, it ensures that compressed air forms a uniform upward laminar flow after passing through the air distribution plate, improving humidification uniformity.

[0039] In one alternative implementation, the multiple sensors include a humidity sensor and a hot-wire anemometer; the humidity sensor is installed at the outlet of the humidification tank to collect the relative humidity of the outlet air; the hot-wire anemometer is used to collect the wind speed at multiple points on the adjustable air distribution plate.

[0040] Specifically, Figure 4 This is a schematic diagram of a sensor according to an embodiment of the present invention, such as... Figure 4 As shown, a humidity sensor is installed at the external outlet at the top of the humidification tank, enabling real-time and accurate collection of the relative humidity of the outlet air. This is the core basis for the control system to determine whether the air humidification meets the standard and to dynamically adjust the spray water volume. A hot-wire anemometer is installed inside the humidification tank to monitor the airflow velocity distribution in the adjustable air distribution plate area. Its monitoring range covers the cross-section of the humidification tank where the air distribution plate is located. Specifically, taking the center of the air distribution plate as a reference, at least 10 evenly distributed monitoring points are selected within a key area with a diameter of 100mm to collect wind speed data. This is the core basis for the control system to dynamically adjust the porosity.

[0041] In one alternative embodiment, the sprinkler system includes multiple nozzles; the control system is also used to combine the multiple nozzles to achieve a target sprinkler volume.

[0042] Specifically, to meet the humidification requirements under high back pressure conditions, the nozzles inside the humidification tank adopt a matrix layout design. That is, all nine nozzles are uniformly installed on the annular plane where the elliptical end cap connects to the cylindrical wall at the top of the humidification tank. This position ensures that the water mist covers the entire cross-section of the humidification tank when sprayed downwards. Among them, one nozzle is located directly below the axis of the humidification tank (i.e., the center position), serving as the core reference for water mist coverage; the remaining eight nozzles are evenly distributed in a ring around the center nozzle, with the axis of each peripheral nozzle 210mm away from the axis of the center nozzle.

[0043] In actual operation, there are several nozzle combination modes: 1 (center nozzle only), 4 (center nozzle + 3 peripheral nozzles), 5 (center nozzle + 4 peripheral nozzles), 8 (8 peripheral nozzles only), and 9 (all nozzles). The control system activates the corresponding nozzle combination according to the target spray water volume, and closes the other nozzles to ensure that the spray water mist is evenly distributed across the cross-section of the humidification tank under high back pressure conditions, providing uniform contact conditions for sufficient heat and moisture exchange between compressed air and water mist.

[0044] In one optional implementation, the air distribution plate and sprinkler heads can also be manually adjusted by the user. The user can manually adjust the porosity of the air distribution plate according to actual needs and record the manual adjustment parameters for subsequent analysis and optimization, or manually adjust the sprinkler heads according to actual needs and record the manual adjustment parameters. Furthermore, the device includes a user interface that provides query and export functions for historical water volume control data, allowing users to view and analyze the water volume control status during device operation at any time.

[0045] It should be noted that the attributes of each component in the above-mentioned device, such as specifications and materials, are merely examples and can be adjusted according to actual circumstances. The embodiments of the present invention do not impose any limitations.

[0046] This invention utilizes a humidification tank to provide a stable humidification space for high-back-pressure compressed air and spray water mist. The control system uses data collected in real time by multiple sensors to determine the target spray water volume and target porosity. This allows an adjustable air distributor in the humidification tank to distribute air according to the target porosity, significantly improving humidification uniformity. The compressed air, rectified by the air distributor, forms a uniform upward laminar flow, exchanging heat and moisture with the water mist sprayed by the spray system according to the target spray water volume, thus achieving humidification of the compressed air. By using multiple sensors to monitor humidification environment parameters in real time from all angles, the target porosity during air distributor rectification and the target spray water volume during spray system humidification can be accurately calculated and adjusted. Compared to the fixed design of air distribution structure and spray water volume in existing humidification devices, this invention ensures uniform and precise humidification of compressed air under high back-pressure conditions, meeting the stable humidity requirements of the process flow and significantly improving the applicability and flexibility of the device under complex operating conditions.

[0047] This embodiment provides a humidification control method, which can be used in the aforementioned high back pressure compressed air humidification device. Figure 5 This is a flowchart of a humidification control method according to an embodiment of the present invention, such as... Figure 5 As shown, the process includes the following steps: Step S501: Acquire data collected by multiple sensors.

[0048] Specifically, the data collected by the sensors is acquired in real time to ensure dynamic capture of key parameters under high back pressure conditions, providing data support for subsequent adjustments.

[0049] In some alternative implementations, if the compressor has just started, i.e., it is in the initial humidification state, an initial spray water volume can be set. The air temperature at the inlet of the humidification tank is obtained from the temperature sensor and the internal pressure of the humidification tank is obtained from the pressure sensor. The initial moisture content is determined by the following formula (1), which is the amount of water required to humidify a unit mass of compressed air. The initial spray water volume can be slightly greater than the product of the mass flow rate of the compressed air and the initial moisture content.

[0050] (1) In the formula, B Indicates the internal pressure of the humidifier tank; Indicates the initial moisture content; This indicates the air temperature at the inlet of the humidifier canister.

[0051] Step S502: Based on the data collected by multiple sensors, determine the target porosity and the target spray water volume.

[0052] Specifically, traditional compressed air humidification methods rely on fixed empirical formulas and cannot adapt to changes in operating conditions. Therefore, this invention dynamically adjusts the output based on real-time sensor data to achieve a target porosity and target spray water volume suitable for high back pressure conditions.

[0053] Step S503: Humidify the compressed air inside the humidification tank based on the target porosity and target spray water volume.

[0054] Specifically, humidification is carried out based on the target porosity and target spray water volume determined in the above steps to ensure that the humidification effect of compressed air is uniform and accurate under high back pressure conditions, and to meet the stable requirements of the process flow for compressed air humidity.

[0055] This invention acquires data from multiple sensors to accurately calculate and adjust the target porosity during air distribution plate rectification and the target spray water volume during spray system humidification. Compared to relying on fixed empirical formulas, it can dynamically output target porosity and target spray water volume that are adapted to high back pressure conditions. This ensures that the humidification effect of compressed air is uniform and accurate under high back pressure conditions, meeting the process flow's requirements for stable compressed air humidity.

[0056] This embodiment provides a humidification control method, which can be used in the aforementioned high back pressure compressed air humidification device. Figure 6 This is a flowchart of another humidification control method according to an embodiment of the present invention, such as... Figure 6 As shown, the process includes the following steps: Step S601: Acquire data from multiple sensors, including wind speed at multiple points on the adjustable air distribution panel and relative humidity of the air outlet from the humidification tank. For details, please refer to [link to relevant documentation].Figure 5 Step S501 of the illustrated embodiment will not be described again here.

[0057] Step S602: For the wind speed at each point of the adjustable air distribution plate, determine the root mean square error of the wind speed at each point and the wind speed at every other point.

[0058] Specifically, for the wind speeds at multiple points on the air distribution plate collected by the hot-wire anemometer, the root mean square error of each point's wind speed compared to all other points is calculated. The root mean square error is a core indicator that quantifies the difference in flow velocity between points. A larger value indicates a more significant wind speed deviation, meaning a more uneven airflow distribution in the area corresponding to the adjustable air distribution plate; conversely, a smaller value indicates that the wind speeds at different points are closer, and the airflow distribution across the cross-section of the air distribution plate is more uniform.

[0059] Step S603: When the root mean square deviation of any wind speed at a given point is greater than a preset value, determine the target porosity of the adjustable air distribution plate.

[0060] Specifically, to accurately determine the uniformity of air distribution under high back pressure conditions, assuming a preset value of 0.2 m / s, if the root mean square difference of wind speed between all points is ≤0.2 m / s, it indicates that the porosity of the adjustable air distribution plate is adapted to the current high back pressure airflow velocity, and the airflow is uniformly distributed across the cross-section of the air distribution plate, so there is no need to adjust the porosity; if the root mean square difference of wind speed between any point is >0.2 m / s, it is determined that the air distribution is not uniform, and the porosity needs to be adjusted to ensure uniform airflow.

[0061] Step S604: Based on the data collected by multiple sensors, determine the target porosity and the target spray water volume.

[0062] Specifically, the target spray water volume is determined by the following formula (2). By combining theoretical calculation with actual feedback, the precise control of the spray water volume is ensured, which not only improves the humidification efficiency but also effectively reduces the outflow of liquid water, further optimizing the humidification effect.

[0063] (2) In the formula, Q Indicates the target spray water volume; Indicates the current spray water volume; and Indicates the adjustment factor; RH This indicates the relative humidity of the outlet air.

[0064] in, This represents the adjustment coefficient used to control the rate of decrease in the spray water volume. The value range is [0.8, 1.2]. When the relative humidity decreases slowly during operation, the upper limit is used; if it decreases quickly, the lower limit is used. This represents the adjustment coefficient used to control the rate of increase in the spray water volume. The value range is [0.8, 1.2]. When the relative humidity increases slowly during operation, the upper limit is used; if it increases rapidly, the lower limit is used.

[0065] The target porosity is determined by the following formula (3): (3) In the formula, Indicates the target porosity; v This represents the average wind speed at multiple points on the adjustable air distribution panel; Indicates the maximum airflow velocity; and This indicates the maximum and minimum porosity.

[0066] Step S605: Based on the target porosity and target spray water volume, humidify the compressed air inside the humidification tank. For details, please refer to [link to relevant documentation]. Figure 6 Step S603 of the illustrated embodiment will not be described again here.

[0067] Step S606: Continuously acquire the relative humidity of the outlet air of the humidification tank.

[0068] Specifically, the relative humidity of the outlet humid air is collected at fixed time intervals (e.g., every 10 seconds) to ensure real-time capture of the dynamic changes in air humidity under high back pressure conditions, avoid over-humidification due to monitoring lag, and minimize liquid water outflow.

[0069] Step S607: When the relative humidity reaches saturation, stop humidifying.

[0070] Specifically, when the relative humidity at the outlet reaches 100%, meaning the air is saturated, it indicates that the current humidification level has met the upper limit of moisture absorption of compressed air under high back pressure conditions. If humidification continues, liquid water will be generated. Therefore, humidification is stopped to ensure that the humidity meets the standard and to avoid the risk of liquid water under high back pressure conditions.

[0071] This invention acquires data from multiple sensors to accurately calculate and adjust the target porosity during air distribution plate rectification and the target spray water volume during spray system humidification. Compared to relying on fixed empirical formulas, it can dynamically output target porosity and target spray water volume that are adapted to high back pressure conditions. This ensures that the humidification effect of compressed air is uniform and accurate under high back pressure conditions, meeting the process flow's requirements for stable compressed air humidity.
