[0023] Various exemplary embodiments of the present application will now be described in detail with reference to the accompanying drawings. It should be noted that: Unless otherwise specifically stated, the relative arrangements, numerical expressions, and numerical values of the components and steps set forth in these embodiments do not limit the scope of the present application.

[0024] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way a limitation on the present application, its application, or use.

[0025] Technologies, methods, and devices known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and devices should be regarded as part of the specification.

[0026] In all the examples shown and discussed here, any specific values should be construed as merely exemplary and not as a limitation. Accordingly, other examples of the exemplary embodiments may have different values.

[0027] The present application provides a steam dryness value monitoring and regulating system for an air-conditioning unit, which separates water vapor in the steam through a steam-water separator, collects the dryness value and physical characteristics of the separated steam at the separated steam outlet of the steam-water separator, preliminarily determines whether the dryness value reaches the alarm threshold based on the physical characteristics, and determines a dryness value regulation scheme for the separated steam based on the dryness value, so that the dryness value is controlled within a preset range, avoiding the corrosion of the blower chamber motor caused by excessive moisture in the steam, as well as the occurrence of water hammer phenomenon in the heater and damage to the heater copper tubes.

[0028] As Figure 1 shown, the steam dryness value monitoring and regulating system for the air-conditioning unit provided by the present application includes a controller, a steam-water separator 5, a monitoring module, an adjusting module, and an alarm.

[0029] The inlet of the steam-water separator 5 is connected to the steam source through a pipeline. The separated steam outlet of the steam-water separator 5 is connected to the separated steam inlet of the monitoring module, and the separated water outlet of the steam-water separator 5 is connected to the condensate recovery system 20 through a condensate recovery pipeline.

[0030] As Figure 1As shown in the figure, a main valve 1, a first filter 2, and a pressure gauge 3 are successively provided on the pipeline between the steam gas source and the inlet of the steam-water separator 5. The main valve 1 can be opened or closed manually or automatically to control the on-off of the steam. Closing the main valve can cut off the steam flow in the entire air-conditioning unit pipeline, playing a role in isolating and protecting the system, facilitating the maintenance and repair of the system, ensuring that the steam supply can be quickly cut off when needed, and preventing the expansion of faults. The first filter 2 preliminarily filters the passing steam to remove larger impurities and particulate matters in the steam. The filtering medium can prevent impurities from entering the subsequent system, reduce the wear and blockage of the equipment, effectively protect the subsequent processing module, extend the equipment life, and improve the stability of the system. The pressure gauge 3 is used to detect the internal pressure of the pipeline when the steam passes through. The steam-water separator 5 is used to separate the gas and water vapor in the steam.

[0031] Preferably, a bypass pipeline is further provided between the steam gas source and the separated steam outlet of the steam-water separator 5, and a bypass valve 4 is provided on the bypass pipeline. When the main valve 1 is closed and the bypass valve 4 is opened, the bypass pipeline is another path for the steam. The function of the bypass valve 4 is to provide another steam path when necessary to ensure the continuous operation of the system or to conduct bypass debugging. When the main valve is closed, the presence of the bypass valve can maintain a certain steam flow rate, avoid the complete stop of the system operation, and improve the flexibility and reliability of the system. A first manual valve 6 is provided between the separated steam outlet of the steam-water separator 5 and the connection port of the bypass pipeline. When the steam-water separator 5 is under maintenance and testing, the first manual valve 6 is closed to assist in the maintenance.

[0032] As Figure 1 shown in the figure, the monitoring module includes a dryness sensor 7 and a probe 8 successively arranged on the pipeline. The probe 8 is used to capture the physical characteristics of the separated steam, such as information about the color of the steam, etc. These physical characteristics reflect the situation when the steam passes through the pipeline. The dryness sensor 7 is used to detect the dryness value of the separated steam.

[0033] As an embodiment, the probe 8 is a chromaticity sensor for detecting the color of the steam. When the content of dry steam in the steam is relatively large, the steam presents a light blue color. When the dry steam in the steam is less and the water vapor is more, the steam presents a white mist shape. Therefore, by detecting the color of the steam with the chromaticity sensor, the situation of the steam passing through the pipeline can be determined. If the value of the chromaticity sensor is not within the preset range, indicating that the dryness value is low and the duration exceeds the preset time (for example, 10 minutes), the controller controls the alarm to send an alarm message, and the duty personnel promptly notify the maintenance personnel for quick repair to ensure the efficient operation of the air-conditioning unit.

[0034] As an embodiment, the adjustment module includes a steam humidifier 9, and a first electric actuator 10 is provided between the steam humidifier 9 and the separated steam outlet of the monitoring module.

[0035] As an embodiment, the steam humidifier 9 is a dry steam humidifier.

[0036] The controller is respectively connected to the alarm, the dryness sensor 7, the probe 8, and the first electric actuator 10. The controller determines whether to alarm and determines the adjustment scheme of the dryness value, such as the humidification target amount, etc., based on the real-time information collected by the probe and the dryness sensor, and then controls the adjustment device in the adjustment module through the first electric actuator to adjust the dryness value.

[0037] As another embodiment, the adjustment module further includes a steam heating device 11, and a second electric actuator 22 is provided between the steam heating device 11 and the separated steam outlet of the monitoring module.

[0038] As an embodiment, as Figure 2 shown, the steam heating device 11 includes a high-pressure unit 13 for pressurizing the steam. A sinking branch pipe 12 is provided on the pipeline between the second electric actuator 22 and the first end of the high-pressure unit 13. The sinking branch pipe 12 is connected to the condensate recovery system 20 through a condensate recovery pipeline. The sinking branch pipe 12 serves as a steam sinking channel, which is a specially designed pipeline for guiding the steam to sink. Through reasonable pipeline layout and inclination design, the steam naturally sinks in it, and the gravity is utilized to promote the flow and distribution of the steam, providing a dedicated channel for the steam to sink, which helps to improve the transmission efficiency and uniformity of the steam. The high-pressure unit 13 is used to pressurize the steam. Increasing the pressure of the steam can increase its temperature and heat capacity, enhance the heating effect, and meet different heating requirements.

[0039] As an embodiment, the high-pressure unit 13 is a spherical high-pressure container.

[0040] Preferably, as Figure 2 shown, a blowdown pipe 23 and a manual blowdown valve 14 are provided on the second end of the high-pressure unit 13. Opening the manual blowdown valve 14 to remove the dirt in the pipeline can effectively remove impurities and ensure the efficient operation of the system. It is preferably to blow down once a week.

[0041] As an embodiment, if the dryness value is less than the preset value, the controller controls the first electric actuator and the second electric actuator to control the operation of the steam humidifier 9 and the steam heating device 11 respectively at the minimum opening (for example, 10%) to reduce the pressure and flow rate of the steam. After the dryness value reaches the preset value, the controller controls the first electric actuator and the second electric actuator to resume automatic adjustment. Since the dry steam humidifier does not spray water, it can protect the motor in the air supply chamber from corrosion and prevent the motor from stopping due to electrical failure alarm, reduce the frequency of failures, and at the same time weaken the water hammer phenomenon generated after the steam-water mixed steam enters the heater, protecting the copper tubes of the heater from damage.

[0042] As an embodiment, the condensate recovery pipeline includes a main pipe 24 and a filtering branch pipe. On the filtering branch pipe, a second filter 16, a steam trap 17 and a check valve 18 are sequentially arranged from the end of the main pipe 24 to the condensate recovery system 20. The second filter 16 is used to filter the separated water and discharge the filtered water through the steam trap 17 and the check valve 18.

[0043] Preferably, a first service valve 15 is arranged at the inlet end of the second filter 16, and a second service valve 19 is arranged at the outlet end of the check valve 18. The first service valve 15 and the second service valve 19 are used for servicing the front and rear ends of the second filter 16.

[0044] On the basis of the above, preferably, the condensate recovery pipeline further includes a manual branch pipe, and a second manual valve 21 is arranged on the manual branch pipe.

[0045] As an embodiment, the sinking branch pipe 12 is communicated with the main pipe 24 through a pipeline.

[0046] Thus, the water separated by the steam-water separator 5 and the water separated by the steam heating device 11 can be directly introduced into the condensate recovery system 20 by opening the second manual valve 21, or can be introduced into the condensate recovery system 20 after being filtered by the filtering branch pipe. In addition, the second manual valve 21 can be opened during the maintenance of the filtering branch pipe to discharge water through the manual branch pipe.

[0047] Based on the above, the principle of the present application is as follows:

[0048] The steam gas source is preliminarily filtered by the first filter 2 and then enters the steam-water separator 5 to separate the gas and water vapor in the steam. The separated water enters the condensate recovery system 20, and the separated steam passes through the dryness sensor 7 and the probe 8 to detect the dryness value and physical characteristics of the steam. When the dryness value of the steam is lower than the set value, the controller determines the opening degrees of the electric actuators of the steam heating device 11 and the steam humidifier 9 according to the dryness value, so as to reduce the pressure and flow rate of the steam, protect the motor in the air supply chamber from corrosion and prevent the motor from alarming and shutting down due to electrical faults, reduce the frequency of faults, and also weaken the water hammer phenomenon generated after the steam-water mixed steam enters the heater to protect the copper tubes of the heater from damage. After the dryness value of the steam is restored, the electric actuators of the steam heating device 11 and the steam humidifier 9 resume automatic adjustment, so that the dryness value of the steam can be adjusted.

[0049] The beneficial effects of the present application are:

[0050] 1. The controller of the present application controls the start / stop and opening degree of the steam heating device and the steam humidifier according to the signals of the monitoring module, so as to achieve precise control of the steam dryness value. The precise control can improve the responsiveness and regulation ability of the system, ensure the accuracy and stability of the heating and humidification operations, thus better meeting the requirements of the steam dryness value, and avoiding the occurrence of water hammer phenomenon after the steam with excessive moisture in the pipeline enters the heater, resulting in damage to the blower chamber motor and the copper tube of the heater.

[0051] 2. The present application measures the flow rate or volume of steam through the dryness sensor to determine the flow rate and detect the presence of moisture, and real-time monitors the steam dryness value. Information such as the color of the steam can be captured through the probe, thereby comprehensively monitoring and controlling the steam dryness value, and providing real-time data and intuitive visual feedback.

Those skilled in the art should understand that the above embodiments can be modified without departing from the scope and spirit of the present application.
