Description

Technical Field

[0001] This utility model belongs to the field of hydrogen combustion technology, and in particular relates to a hydrogen flameless burner that is easy to install. Background Technology

[0002] The hydrogen flameless burner is an advanced device that utilizes the principle of catalytic oxidation to achieve efficient and clean energy conversion of hydrogen. Its core lies in the use of a specialized catalyst with high activity and selectivity. Through catalysis, hydrogen (H2) and oxygen (O2) undergo a mild and controllable redox reaction on the catalyst surface, rather than the violent gas-phase combustion reaction of traditional methods. This completely eliminates visible flames, significantly reduces the formation of localized high-temperature zones, and greatly suppresses the generation of thermal nitrogen oxides (NOx). The combustion process takes place on the catalyst surface in a near-isothermal manner. The released heat is effectively transferred and utilized through heat conduction, radiation, or heating of the medium flowing across its surface (such as air, water, or other process fluids). It features relatively uniform reaction temperature, no open flame, no flashing, extremely low combustion noise, and near-zero pollutant emissions (the main product is water vapor).

[0003] The burner is directly fixed to the combustion chamber wall or the equipment body using rigid supports to ensure stability under high-temperature conditions. Flanges or high-pressure resistant metal bellows are used to connect to the external hydrogen / air premixed supply system, achieving high-pressure sealing and leak-proof operation of the gas source. However, because the support welding / bolting is required within the narrow combustion chamber, the limited operating space prevents the entry of large tools, resulting in low installation efficiency. This can easily lead to increased installation errors or support angle misalignment, resulting in poor sealing and the risk of hydrogen leakage. Summary of the Invention

[0004] In view of this, the present invention aims to at least partially solve one of the related technical problems.

[0005] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0006] A flameless hydrogen burner that is easy to install includes a burner body, a fixing component, a mounting component, a first sealing structure, a second sealing structure, and multiple quick-release connection structures.

[0007] The locking ends of the multiple quick-release connecting structures are evenly arranged circumferentially on the fixing component, and the fixing ends of the multiple quick-release connecting structures are evenly arranged circumferentially on the mounting component.

[0008] The fixing component is disposed on the outer wall of the burner body, the mounting component is connected to the inner wall of the combustion chamber, and the fixing component and the mounting component are connected by multiple quick-release connection structures.

[0009] The mounting assembly is sleeved on the outside of the fixed end of the burner body. The first sealing structure is used to seal the gap between the inner wall of the mounting assembly and the burner body, and the second sealing structure is used to seal the gap between the mounting assembly and the fixed assembly.

[0010] Furthermore, the fixing component is a flange plate, which is fixedly connected to the outer wall of the burner body; the mounting component includes a mounting sleeve and a flange bend, with the flange bend disposed at one end of the mounting sleeve.

[0011] Furthermore, the quick-release connection structure includes a rotary locking assembly and a fixing sleeve. The rotary locking assembly is disposed on the flange plate, and the fixing sleeve is disposed on the flange bend. The rotary locking assembly and the fixing sleeve are detachably connected.

[0012] Furthermore, the rotary locking assembly includes a rotary base, a fixed rod, a rotary lever, and multiple helical protrusions. The rotary base is disposed at one end of the fixed rod, and the fixed rod is rotatably engaged with the flange plate. The rotary lever passes through the rotary base, and the multiple helical protrusions are evenly arranged circumferentially on the outer wall of the fixed rod. The inner wall of the fixed sleeve is provided with helical grooves that can engage with the helical protrusions.

[0013] Furthermore, the quick-release connection structure also includes a ring magnet, which is sleeved on the fixing rod. One side of the ring magnet is fixed to the end face of the flange plate, and the other side of the ring magnet is used to attract the outer end of the fixing sleeve.

[0014] Furthermore, the first sealing structure includes a plurality of high-temperature resistant sealing rings, which are arranged on the inner wall of the mounting sleeve.

[0015] Furthermore, the second sealing structure includes an annular high-temperature resistant gasket, which is sleeved on the outside of the burner body, and the inner end face of the flange plate is bonded to the high-temperature resistant gasket.

[0016] Furthermore, it also includes multiple spring positioning pins, which are evenly arranged circumferentially on the outer wall of the burner body. The spring positioning pins are located inside the flange plate, and the inner wall of the mounting sleeve is provided with an annular positioning groove that can cooperate with the spring positioning pins.

[0017] Furthermore, the flange bend is provided with multiple waist-shaped holes evenly distributed around its circumference.

[0018] Compared with existing technologies, the easy-to-install hydrogen flameless burner of this utility model has the following advantages:

[0019] 1. The quick-release connection structure achieves rapid assembly and disassembly through the helical engagement of the rotary locking component and the fixed sleeve. Simply rotating the rotary lever allows the helical protrusion of the fixed rod to engage or disengage with the helical groove of the fixed sleeve. The operation is simple and requires no additional tools. The self-locking characteristic of the helical structure effectively prevents loosening due to vibration during operation. The ring magnet assists in the precise alignment of the fixed sleeve and the flange plate during installation. The magnetic attraction enhances the stability of the connection, while the tight contact of the helical sealing surface further improves the sealing effect of the hydrogen medium. The combination of rotary locking and magnetic assistance ensures the reliability of the connection and greatly simplifies the disassembly and assembly process during maintenance.

[0020] 2. The fixed assembly, as the core rigid structure connecting the burner and the equipment body, eliminates connection gaps through integrated fixing (such as welding) with the burner body, thus avoiding the risk of hydrogen leakage at the source; the annular high-temperature resistant sealing gasket bonded to the inner end face forms a double seal with the inner wall of the mounting sleeve of the mounting assembly, effectively isolating hydrogen from the external environment; at the same time, the inner side of the flange plate is equipped with a spring positioning pin to guide the precise positioning of the burner when it is inserted into the mounting sleeve, ensuring the coaxiality of the burner and the combustion chamber.

[0021] 3. The installation assembly achieves a transitional connection between the burner and the equipment body through the combination of the installation sleeve and the flange bend. Multiple high-temperature resistant sealing rings on the inner wall of the installation sleeve fit tightly against the outer wall of the burner body, forming multiple sealing barriers to effectively prevent hydrogen leakage. The annular positioning groove on the inner wall cooperates with the spring positioning pin of the burner to achieve axial positioning after the burner is inserted, avoiding positional deviation during installation.

[0033] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0034] An easy-to-install hydrogen flameless burner, such as Figure 1As shown, it includes a burner body 100, a fixing component 300, an installation component 500, a first sealing structure, a second sealing structure 620, and multiple quick-release connection structures; the locking ends of the multiple quick-release connection structures are evenly arranged circumferentially on the fixing component 300, and the fixing ends of the multiple quick-release connection structures are evenly arranged circumferentially on the installation component 500.

[0035] The fixing component 300 is set on the outer wall of the burner body 100, and the mounting component 500 is connected to the inner wall of the combustion chamber. The fixing component 300 and the mounting component 500 are connected by multiple quick-release connection structures. As the core rigid structure connecting the burner and the equipment body, the fixing component 300 eliminates the connection gap through integrated fixing (such as welding) with the burner body 100, thus avoiding the risk of hydrogen leakage at the source. The annular high-temperature resistant sealing gasket bonded to the inner end face forms a double seal with the inner wall of the mounting sleeve 520 of the mounting component 500, effectively isolating hydrogen from the external environment. At the same time, the inner side of the flange plate is equipped with a spring positioning pin 610 to guide the precise positioning of the burner when it is inserted into the mounting sleeve 520, ensuring the coaxiality of the burner and the combustion chamber.

[0036] like Figure 5 As shown, the mounting assembly 500 is sleeved on the outside of the fixed end of the burner body 100. The first sealing structure is used to seal the gap between the inner wall of the mounting assembly 500 and the burner body 100, and the second sealing structure 620 is used to seal the gap between the mounting assembly 500 and the fixed assembly 300. The fixed assembly 300 is a flange plate, which is fixedly connected to the outer wall of the burner body 100. The mounting assembly 500 includes a mounting sleeve 520 and a flange bend 510, with the flange bend 510 located at one end of the mounting sleeve 520. The mounting assembly 500, through the combination of the mounting sleeve 520 and the flange bend 510, achieves a transitional connection between the burner and the equipment body. Multiple high-temperature resistant sealing rings on the inner wall of the mounting sleeve 520 are tightly fitted to the outer wall of the burner body 100, forming multiple sealing barriers to effectively prevent hydrogen leakage. The annular positioning groove 530 on the inner wall cooperates with the spring positioning pin 610 of the burner to achieve axial positioning of the burner after insertion, avoiding positional deviation during installation. Multiple slotted holes are evenly distributed around the circumference of the flange bend (510mm).

[0037] The quick-release connection structure includes a rotary locking assembly and a fixing sleeve 460. The rotary locking assembly is mounted on the flange plate, and the fixing sleeve 460 is mounted on the flange bend 510. The rotary locking assembly and the fixing sleeve 460 are detachably connected. The rotary locking assembly includes a rotary base 430, a fixing rod 410, a rotary lever 450, and multiple helical protrusions 420. The rotary base 430 is located at one end of the fixing rod 410, and the fixing rod 410 is rotatably engaged with the flange plate. The rotary lever 450 passes through the rotary base 430. The multiple helical protrusions 420 are evenly arranged circumferentially on the outer wall of the fixing rod 410. The inner wall of the fixing sleeve 460 has helical grooves that can mate with the helical protrusions 420. The quick-release connection structure also includes an annular magnet 470, which is sleeved on the fixing rod 410. One side of the annular magnet 470 is fixed to the end face of the flange plate, and the other side of the annular magnet 470 is used to attract the outer end of the fixing sleeve 460.

[0038] The quick-release connection structure achieves rapid assembly and disassembly through the rotation locking assembly and the spiral engagement of the fixing sleeve 460. Simply rotating the rotating lever 450 allows the spiral protrusion 420 of the fixing rod 410 to engage or disengage with the spiral groove of the fixing sleeve 460. The operation is simple and requires no additional tools. The self-locking characteristic of the spiral structure effectively prevents loosening due to vibration during operation. The annular magnet 470 assists in the precise alignment of the fixing sleeve 460 with the flange plate during installation. The magnetic attraction enhances the stability of the connection, while the tight contact of the spiral sealing surface further improves the sealing effect of the hydrogen medium. The combination of rotation locking and magnetic assistance ensures the reliability of the connection and greatly simplifies the disassembly and assembly process during maintenance.

[0039] The first sealing structure includes multiple high-temperature resistant sealing rings, which are arranged on the inner wall of the mounting sleeve 520. The second sealing structure 620 includes an annular high-temperature resistant gasket, which is fitted onto the outer side of the burner body 100, and the inner end face of the flange plate is bonded to the high-temperature resistant gasket.

[0040] Multiple spring positioning pins 610 are evenly arranged on the outer wall of the burner body 100. The spring positioning pins 610 are located on the inner side of the flange plate. The inner wall of the mounting sleeve 520 is provided with an annular positioning groove 530 that can cooperate with the spring positioning pins 610.

[0041] How this example works

[0042] Step 1: Align the flange bend 510 of the mounting assembly 500 with the corresponding mounting position on the equipment body (inner wall of the combustion chamber). Adjust the position using the evenly spaced oblong holes around the flange bend 510 to accommodate installation errors of the equipment body. Ensure that the axis of the mounting sleeve 520 coincides with the center line of the combustion chamber. Then, use bolts to initially fix the flange bend 510 to the equipment body. At this point, the mounting sleeve 520 forms a support frame for burner insertion, and the annular positioning groove 530 on its inner wall and the high-temperature sealing ring are ready to receive the burner.

[0043] Step 2: Align the fixed end of the burner body 100 with the opening of the mounting sleeve 520 of the mounting assembly 500, and slowly insert it axially. During the process, the spring positioning pin 610 on the outer wall of the burner is gradually inserted into the annular positioning groove 530 under the guidance of the inner wall of the mounting sleeve 520, so as to realize the axial positioning of the burner and the mounting sleeve 520 and ensure the coaxiality of the burner and the combustion chamber. At the same time, the multiple high-temperature resistant sealing rings on the inner wall of the mounting sleeve 520 are tightly fitted with the outer wall of the burner body 100 to form multiple sealing barriers to prevent hydrogen leakage.

[0044] Step 3: Rotate the rotating lever 450 on the burner flange plate to rotate the fixing rod 410. This causes the spiral protrusion 420 on the outer wall of the fixing rod 410 to gradually engage with the spiral groove of the fixing sleeve 460 on the flange bend 510 of the mounting sleeve 520. As the rotation angle increases, the spiral structure generates a radial locking force, tightly pressing the flange plate and the flange bend 510 together. At this time, the annular magnet 470 magnetically attracts the outer end of the fixing sleeve 460, assisting in the precise alignment of the fixing sleeve 460 and the flange plate, enhancing the stability of the connection. The tight contact of the spiral sealing surface further improves the sealing effect of the hydrogen medium.

[0045] Step 4: Check whether the annular high-temperature resistant sealing gasket bonded to the inner end face of the flange plate is completely fitted with the end of the mounting sleeve 520 to ensure the effectiveness of the second sealing structure 620. At the same time, confirm whether the rotating lever 450 of the quick-release connection structure has been rotated to the locking position and whether the annular magnet 470 firmly attracts and fixes the sleeve 460. Finally, adjust the final position of the mounting component 500 through the waist-shaped hole of the flange bend 510, tighten the bolts to completely fix the mounting component 500 to the equipment body, and complete the installation of the burner. At this time, the burner and the equipment body form a rigid connection, and the sealing state meets the safety requirements of flameless combustion of hydrogen.

[0046] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
