Description

Technical Field

[0001] This utility model relates to the field of hydrogen-assisted coal-fired boiler technology, specifically to a hydrogen leak prevention monitoring device for a hydrogen-assisted coal-fired boiler. Background Technology

[0002] A hydrogen-assisted coal-fired boiler is a hybrid fuel boiler system that combines hydrogen and coal. The main purpose of this system is to improve combustion efficiency, reduce pollutant emissions, and utilize the high energy density of hydrogen to enhance the boiler's heat output. By introducing hydrogen into the coal combustion process, the boiler enhances the combustion process, increasing the combustion temperature and promoting complete coal combustion, thereby improving the boiler's thermal efficiency. Hydrogen combustion produces fewer pollutants, helping to reduce environmental pollution during boiler operation. In conclusion, the hydrogen-assisted coal-fired boiler is a promising hybrid fuel boiler system that can play a significant role in improving thermal efficiency and reducing pollutant emissions.

[0003] While hydrogen-assisted coal-fired boilers offer numerous advantages, hydrogen monitoring is essential for their safe operation. Therefore, hydrogen leak prevention monitoring equipment is required. Traditional hydrogen leak prevention monitoring equipment, although capable of monitoring, has several shortcomings. For example, its mounting components have a relatively fixed structure, making it difficult to adapt to different installation environments and limiting its installation range. Furthermore, its protection of hydrogen sensors is inadequate, making them susceptible to damage from external factors when not monitoring, thus compromising its lifespan. Therefore, this paper proposes a hydrogen leak prevention monitoring device for hydrogen-assisted coal-fired boilers to address these issues. Summary of the Invention

[0028] A hydrogen leak prevention monitoring device for a hydrogen-assisted coal-fired boiler includes a fixed bracket 1. Mounting components 2 are symmetrically arranged on the top of both side walls of the fixed bracket 1. A fixing groove 3 is formed at the center of the top of the fixed bracket 1, and an audible and visual alarm 4 is fixedly embedded in the fixing groove 3. A connecting support plate 5 is provided below the fixed bracket 1, and the connecting support plate 5 is connected to the fixed bracket 1 via a fixing component 6. A hydrogen sensor 7 is fixedly connected to the center of the bottom of the connecting support plate 5. A sealing sleeve 8 is provided below the connecting support plate 5, and the sealing sleeve 8 is connected to the connecting support plate 5 via a connecting component 9. The fixed bracket 1 has a U-shaped structure, with the mounting components 2 arranged on the outer upper end.

[0029] Mounting assembly 2 includes a mounting plate 201 with its top flush with the top of the fixed bracket 1. The mounting plate 201 has several equally spaced and penetrating mounting holes 202, one of which is pierced by a matching mounting bolt 203. Mounting assembly 2 provides good installation capability for the fixed bracket 1 and its flexible structure allows for adaptive adjustment to different installation environments, thus broadening its installation range. Fixing assembly 6 includes symmetrical fixing bolts 601 piercing both sides of the fixing groove 3 and symmetrical fixing screw holes 602 on the top of the connecting support plate 5. The fixing bolts 601 and fixing screw holes 602 are positionally corresponding and of matching specifications. The connecting support plate 5 can be connected to the fixed bracket 1 via the fixing assembly 6. The connecting component 9 includes positioning blocks 901 that are equidistantly spaced and fixedly connected to the top wall frame of the closed sleeve 8, and positioning slots 902 that are equidistantly spaced and opened at the bottom of the connecting support plate 5. The positioning blocks 901 and positioning slots 902 are equal in number, corresponding in position, and matching in specifications. The connecting component 9 also includes hinges 903 symmetrically arranged on both sides of the connecting support plate 5 and fastening slots 904 symmetrically and fixedly connected to the top of both sides of the closed sleeve 8. Fastening buckles 905 are rotatably connected to the hinges 903. The fastening buckles 905 and fastening slots 904 are corresponding in position and matching in specifications. The fastening buckles 905 are C-shaped plates with right angles at the corners. The upper part is connected to the connecting support plate 5 through the hinges 903, and the lower part corresponds to the fastening slots 904. The connecting component 9 can provide good connection capability and structural stability between the enclosed sheath 8 and the connecting support plate 5, thereby ensuring the protective effect of the enclosed sheath 8 on the hydrogen sensor 7.

[0030] Workflow: First, power on all electrical appliances and connect them to external controllers. The fixed bracket 1 provides a connection base for the entire system. The mounting component 2 provides good installation capability for the fixed bracket 1, and its flexible structure allows for adaptability to different installation environments, resulting in a wide installation range. During installation, first place the fixed bracket 1 at the installation location. Then, select the appropriate mounting through hole 202 on the mounting plate 201 according to the actual installation conditions. Screw the mounting bolt 203 into the installation location through this mounting through hole 202. Multiple mounting through holes 202 provide multiple installation paths for the mounting bolt 203, ensuring installation flexibility. The fixing slot 3 can be used to install the audible and visual alarm 4. The audible and visual alarm 4 can provide an audible and visual alarm when hydrogen leakage is detected, serving as a warning. The connecting bracket 5, through the fixing component 6, allows the hydrogen sensor 7 to be installed between the fixed bracket 1 and the fixed bracket 1, facilitating disassembly. During installation, first place the connecting bracket 5 below the fixed bracket 1 and align the fixing screw hole 602 with the fixing screw... The fixing bolt 601 is aligned with the hole position of bolt 601. Finally, the fixing bolt 601 is screwed into the fixing screw hole 602. Disassembly and maintenance follow the same procedure. The hydrogen sensor 7 monitors the hydrogen concentration in the boiler's operating environment. A threshold is preset in the hydrogen sensor 7. When the hydrogen sensor 7 detects that the current hydrogen concentration exceeds the standard, it transmits the information to the controller. The controller then activates the audible and visual alarm 4 to trigger an audible and visual alarm. The enclosed protective sleeve 8 can shield the hydrogen sensor 7 when not in use, thus preventing damage from external factors when not monitoring. To ensure its service life, the connecting component 9 provides good connection capability and structural stability between the closed sheath 8 and the connecting support plate 5, thereby ensuring the protective effect of the closed sheath 8 on the hydrogen sensor 7. During protection, first place the closed sheath 8 under the hydrogen sensor 7 and move it up to cover the hydrogen sensor 7. At the same time, insert the positioning blocks 901 one by one into the corresponding positioning slots 902 for positioning and locking. Finally, the fastening buckle 905 is rotated into the fastening slot 904 by the hinge 903 for fastening and locking. The same method applies to disassembly.
