[0002] In the prior art, anti-corrosion measures for circulating fluidized bed boilers primarily include drying using waste heat from hot boiler water discharge and drying using ammonia alkalization. However, these methods have significant drawbacks: First, when using these methods for anti-corrosion treatment, the rapid drop in boiler bed temperature makes it difficult to completely drain accumulated water from the water-cooled walls and elbow areas of the superheater, forming so-called "dead zones" that affect the drying effect. Furthermore, the relative humidity of the air inside the boiler fails to meet ideal anti-corrosion standards, which not only accelerates the corrosion process of the boiler's metal components but also reduces the performance of the boiler materials, negatively impacts the boiler's heat transfer efficiency, and ultimately increases maintenance costs.

[0003] On the other hand, traditional air compressors and humidity detection devices often lack effective interconnection mechanisms. Even if a connection is established, it often relies on wired connections, which limits the flexibility and mobility of the equipment. This limitation is particularly evident in practical applications, because different boilers or work areas may require different dehumidification strategies, and existing fixed dehumidification equipment cannot meet these requirements. Summary of the Invention

Therefore, the terms used in the specification should not be understood as simple names, but rather as the meanings of the terms and the overall description of the present invention.

[0026] Reference Figure 1 This embodiment provides a mobile automatic boiler furnace dehumidification device, including a mobile cart 15 mounted at the bottom of an air compressor 11, making the entire system highly flexible and mobile. A LoRa module 16 is installed at the top of the air compressor 11. This module houses either a built-in air compressor controller or a control system that can connect to an external LoRa communication device. This module utilizes LoRa technology for wireless data transmission, eliminating the need for traditional wired connections.

[0027] Mobile module 1, mobile module 1 includes an air compressor 11, which is used to provide compressed gas; main module 2, main module 2 monitors environmental data and transmits the data to mobile module 1; boiler module 3, mobile module 1 transports treated compressed gas into the boiler to achieve dehumidification; a dryer 12 is installed at the outlet of the air compressor 11, which is used to adjust the temperature and humidity of the compressed air; the dryer 12 is connected to the bottom of the boiler through a hose 13, and an automatic drain valve 14 is provided at the interface of the hose 13 to prevent moisture from accumulating inside the boiler.

[0028] Reference Figure 1 As an optional embodiment, a mobile trolley 15 is installed at the bottom of the air compressor 11, so that it can be flexibly moved to boilers in different locations, and a LoRa module 16 is provided at the top of the air compressor 11, wherein the LoRa module 16 is provided with an air compressor controller or a control system that can be externally connected to a LoRa communication device for wireless data transmission and remote control.

[0029] The air compressor 11 is equipped with a pressure gauge, a temperature sensor and a safety valve for real-time monitoring of the equipment's operating parameters and making corresponding adjustments.

[0030] The main module 2 includes a server 21, wherein a LoRa gateway body 22 is installed on the side wall of the server 21, which is responsible for receiving and processing data from the humidity detection device.

[0031] Reference Figure 1 As an optional embodiment, the boiler module 3 includes a boiler body 31 , a drain valve 32 is installed on the side wall of the boiler body 31 , and an exhaust valve 34 is installed on the top of the boiler body 31 .

[0032] A humidity detection device 33 is provided at the outlet of the exhaust valve 34. The humidity detection device 33 automatically starts or stops the air compressor 11 according to a preset humidity threshold value to keep the relative humidity inside the boiler below 60%.

[0033] The humidity detection device 33 and the air compressor 11 controller are configured with the same LoRa network parameters, including operating frequency band, transmission rate and spreading factor.

[0034] It should be noted that the pressure gauge, temperature sensor, and safety valve installed on air compressor 11 monitor the equipment's operating parameters in real time and adjust them as needed to ensure safe system operation. The humidity detection device 33 and the air compressor controller are configured with the same LoRa network parameters (such as operating frequency band, transmission rate, and spreading factor), ensuring that they can communicate normally on the same LoRa network.

[0035] Reference Figure 1 In one embodiment provided herein, the LoRa module 16 includes at least one LoRa gateway that supports 4G / 5G communication networks to enable remote data transmission. This enables remote data transmission, greatly improving the convenience and adaptability of device deployment. This design not only simplifies system wiring, but also reduces maintenance costs and improves industrial production efficiency.

[0036] The humidity detection device 33 is connected to the server 21 through the LoRa module 16 and can transmit humidity data to the server 21. The server 21 stores, analyzes and processes the humidity data, makes corresponding control decisions based on preset rules and feeds back to the LoRa module 16. The LoRa module 16 then sends instructions to the controller in the air compressor 11 to implement operations such as starting, stopping and adjusting the operating parameters of the air compressor 11.

[0037] An air inlet 111 and an exhaust port 112 are provided on the side wall of the air compressor 11 , wherein the exhaust port 112 is connected to a safety valve through a pipeline.

[0038] A movable cart 15 is installed at the bottom of the small air compressor 11 to facilitate its later movement to a different boiler location. The controller of the air compressor 11 is equipped with a LoRa module 16, or a control system that can be connected to an external LoRa communication device. The air compressor 11 itself is equipped with necessary safety devices (such as a pressure gauge, temperature sensor, and pressure relief valve) to monitor operating parameters in real time and adjust them as needed.

[0039] A dryer 12 is installed at the outlet of a portable small air compressor 11. By controlling the temperature of the compressed air at the exhaust port 112 of the compressor 11, its initial parameters are increased, thereby increasing the air temperature and reducing the humidity. A hose connects the treated compressed air to the drain valve 32 at the bottom of the boiler, where it is delivered to the heating surface tube bundle inside the boiler. The moisture transfer properties of the steam evaporate the moisture in the air, achieving a dehumidification effect. An automatic drain valve 14 is installed at the interface of the hose 13 to prevent moisture from re-depositing inside the boiler and facilitate timely drainage.

[0040] A humidity detector 33 supporting LoRa communication is installed on the steam header exhaust valve 34 to monitor the air humidity inside the boiler in real time. A LoRa network is built using LoRa technology, and a LoRa module 16 (supporting 4G / 5G communication networks) is installed in a suitable location to establish a connection with the server 21, which is responsible for receiving and forwarding data from LoRa terminal devices.

[0041] Configure the LoRa modules 16 of the humidity detection device 33 and the controller in the air compressor 11, including parameters such as the operating frequency band, transmission rate, and spreading factor, to ensure that they operate under the same LoRa network parameters. Add the humidity detection device 33 and the controller in the air compressor 11 to the deployed LoRa network through the LoRa module 16, perform network registration and authentication, and ensure that the devices can communicate normally on the network.

[0042] The humidity detection device 33 acts as a terminal node, collecting real-time environmental humidity data and sending it to the LoRa gateway via the LoRa network. The LoRa gateway then transmits the data to the server 21 via the 4G / 5G communication network. The server 21 stores, analyzes, and processes the received humidity data, and makes corresponding control decisions based on preset rules and algorithms and feeds them back to the LoRa gateway.

[0043] LoRa module 16 sends the command to the air compressor controller. The controller, acting as a receiving and control node, analyzes and processes the data and controls the operating status of air compressor 11, enabling operations such as starting and stopping the compressor and adjusting operating parameters. According to the interlocking settings, air compressor 11 automatically stops when the relative humidity in the boiler falls below 60% and automatically starts when it exceeds 60%.

[0044] When humidity exceeds a preset normal range, server 21 automatically issues an alarm signal, notifying relevant personnel via text message, app push notification, and other methods so that timely measures can be taken to prevent damage to production equipment caused by abnormal humidity. Humidity data and the operating status of air compressor 11 can be recorded. By analyzing historical data, humidity trends and the operating patterns of air compressor 11 can be understood, providing data support for equipment maintenance and production plan adjustments, helping to optimize production processes and improve production efficiency.

[0045] Relevant personnel can remotely view humidity data and the operating status of the air compressor 11 anytime and anywhere through mobile phones, computers and other terminal devices, and perform remote control operations, which improves the convenience and efficiency of equipment management and realizes intelligent remote management.

[0046] Reference Figure 2-Figure 3 In some implementations, the present embodiment differs from the above embodiments in that a moving wheel 11 a is directly provided on the side wall of the air compressor 11 , and a handle 11 b is installed on the top of the air compressor 11 .

[0047] Since the moving wheel 11a is directly connected to the air compressor 11, the moving wheel 11a and the air compressor 11 are connected through a U-shaped bracket 11c to reduce pressure concentration. The direct contact surface between the U-shaped bracket 11c and the moving wheel 11a is G, which is a flat surface. The connection between the U-shaped bracket 11c and the air compressor 11 is E, F, which fits the curved surface of the air compressor 11.

[0048] Among them, the connecting ends of the U-shaped bracket 11c are set in arc shape as B and D, which can effectively reduce damage caused by pressure concentration. At the same time, the arc shape of the D surface is set as a buffer point, which can effectively reduce damage to the air compressor 11 caused by stress concentration.

[0049] Reference Figure 4 In some implementations, the present embodiment differs from the above embodiments in that the mobile cart 15 is changed to a liftable type.

[0050] The lifting structure can effectively adjust the installation position according to actual conditions, thereby effectively improving the installation efficiency.

[0051] Finally, it should be pointed out that the methods and devices described in detail above are merely embodiments, and those skilled in the art can modify these embodiments in different ways without departing from the scope of the present invention.
