Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of regenerative combustion, in particular to a combined regenerative burner gas multi-jet structure. BACKGROUND

[0002] The basic control unit of the common regenerative combustion system is usually composed of a pair of regenerative burners and a corresponding reversing valve group. In the existing combined regenerative burner technology, the gas jet generally adopts a single jet structure. This single jet design plays a certain role in preventing the gas of the reversing jet burner from being sucked away by the adjacent exhaust burner, causing gas short circuit. Usually, in order to reduce the risk of gas being sucked away, the single gas jet is arranged at the lower part of the combined burner.

[0003] However, this arrangement also brings some problems. Because the single gas jet is far away from the ignition burner, ignition becomes more difficult in the cold state. This is because the gas needs a long path to reach the ignition area, causing insufficient mixing of gas and air when igniting, making it difficult to form a stable flame. In addition, once the flame is ignited, due to the uneven mixing of gas and air, deflagration phenomenon is easy to occur, which not only causes damage to the combustion equipment, but also may pose a safety hazard to the operator. SUMMARY

[0004] The utility model provides a combined regenerative burner gas multi-jet structure, which solves the problem of difficult ignition and unstable combustion caused by uneven mixing of gas and air in the prior art.

[0005] The technical solution of the utility model is as follows:

[0006] A combined regenerative burner gas multi-jet structure, comprising a support frame, a ignition jet is arranged on the support frame, a plurality of gas jets are arranged on the support frame, the end of the gas jet is connected through an air pipe, the side wall of the air pipe is provided with a gas outlet, a gas mixing pipe is rotatably arranged at the gas outlet, the side wall of the gas mixing pipe is communicated with an air outlet pipe, the air outlet pipe corresponds to the gas outlet, the air outlet pipe faces the ignition jet, the side wall of the gas mixing pipe is provided with a fan-shaped worm gear, a worm is rotatably arranged on the support frame and matched with the worm gear.

[0007] Further, the air pipe is provided with a plurality of clamping grooves, and a clamping ring is clamped in each clamping groove, the clamping ring is rotationally connected with the air pipe, a notch is arranged on the clamping ring, the outer diameter of the clamping ring is greater than that of the air pipe, the gas mixing pipe comprises a C-shaped pipe provided with an opening on the side wall, a boss is arranged on the inner side wall of the C-shaped pipe, the boss can be arranged in the notch of the clamping ring, the boss and the clamping ring cooperate to form a sealing ring, the outer side surface of the clamping ring is in abutment with the inner wall of the C-shaped pipe, and the two ends of the opening of the C-shaped pipe are fixedly provided with fixed plates and are fixedly connected through bolts. Through the cooperation of the C-shaped pipe and the clamping groove, the stable sealing effect can be achieved, and the rotation of the gas mixing pipe can be ensured.

[0008] Further, a plurality of spiral guide plates are arranged in the air inlet of the air pipe. The air flow guided by the guide plates can be more effectively mixed with the gas sprayed from the gas nozzle, improving the mixing efficiency.

[0009] Further, the gas nozzle is three, and the diameter of the gas nozzle is 20mm. Through reasonable layout, the uniform distribution of gas in the combustion chamber can be ensured, and the safety hidden danger caused by local overheating or insufficient combustion can be avoided.

[0010] Further, the adjacent gas nozzles are each provided with a gas mixing pipe. The plurality of gas mixing pipes ensure that the mixed gas sprayed from each gas nozzle has similar composition and flow rate, thereby improving the uniformity and stability of combustion.

[0011] Further, the end of the air outlet pipe is provided with a hinged rod, and a baffle is hingedly connected to the hinged rod through a high-temperature-resistant torsional spring. The baffle can close the air outlet pipe under the torsional force of the torsional spring. The baffle can close the air outlet pipe under the action of the torsional spring, prevent foreign matters such as impurities from entering the air outlet pipe, and avoid blockage caused by impurity accumulation.

[0012] Further, a filter screen is arranged in the air outlet pipe. The impurities entering the air outlet pipe can cause blockage, gas pressure rise and incomplete combustion, etc. By arranging the filter screen, the occurrence of these safety hazards can be reduced, and the overall safety of the system can be improved.

[0013] The technical scheme can produce the beneficial effects.

[0014] The present application can conveniently adjust the spraying direction of the gas mixing pipe and the connected air outlet pipe through the cooperation of the worm and the worm gear. This adjustment method is not only accurate but also stable, which ensures that the mixed gas can directly aim at the ignition nozzle, and further promotes the full combustion of the gas. By introducing air into the air pipe and mixing with the gas, the amount of oxygen required for gas combustion is increased, which helps the gas to burn more fully, thereby improving the overall combustion efficiency. The design of multiple gas nozzles not only increases the release area of the gas, but also helps the gas to mix with air, thereby improving the utilization rate of heat energy, so that the heat generated by combustion can be more effectively utilized.

DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0025] As Figures 1-3The utility model provides a kind of combined heat storage burner gas multi-jet structure as shown in figure 7, the utility model provides a kind of combined heat storage burner gas multi-jet structure, including support frame 1, support frame 1 is equipped with ignition jet 2, support frame 1 is equipped with multiple gas jet 3, the end of gas jet 3 is connected by air pipe 4, the lateral wall of air pipe 4 is equipped with gas outlet 5, gas outlet 5 is sealed rotation with gas mixing pipe 6, the lateral wall of gas mixing pipe 6 is communicated with gas outlet pipe 7, gas outlet pipe 7 corresponds with gas outlet 5, gas outlet pipe 7 is towards ignition jet 2, the lateral wall of gas mixing pipe 6 is equipped with fan-shaped worm gear 8, support frame 1 is rotationally equipped with worm 9 matched with worm gear 8.

[0026] In use, air is introduced into air pipe 4, and the air mixes with the gas from gas jet 3 as it passes through air pipe 4. By introducing air into air pipe 4 and mixing it with the gas, the oxygen required for combustion of the gas is increased, thereby improving combustion efficiency. The mixed gas passes through gas outlet 5, gas mixing pipe 6 and gas outlet pipe 7 in turn, and is finally discharged from the gas outlet 5 of gas outlet pipe 7. To adjust the direction of the mixed gas corresponding to ignition jet 2, worm 9 is rotated, causing worm 9 to drive gas mixing pipe 6 to rotate along the axis of air pipe 4 via worm gear 8. The rotation of gas mixing pipe 6 causes gas outlet pipe 7 to oscillate, thereby accurately adjusting the direction of the mixed gas, ensuring that the mixed gas can be directly aimed at ignition jet 2, further promoting the complete combustion of the gas. The self-locking nature of the cooperation between worm 9 and worm gear 8 ensures the fixation of the angle of gas outlet pipe 7, avoiding changes in angle due to air flow or vibration during combustion, thereby ensuring a continuous and stable ignition and combustion state. The design of multiple gas jets 3 not only increases the release area of the gas, but also makes the combustion more uniform, improving the utilization rate of heat energy.

[0027] As shown in Figures 3-7 The air pipe 4 is provided with a plurality of clamping grooves 10, and the clamping grooves 10 are clamped with clamping rings 11, the clamping rings 11 are rotationally connected with the air pipe 4, the clamping rings 11 are provided with notches 12, the outer diameter of the clamping rings 11 is greater than the air pipe 4, the gas mixing pipe 6 includes a C-shaped pipe 13 provided with an opening in the lateral wall, the inner lateral wall of the C-shaped pipe 13 is provided with a boss 14, the boss 14 can be placed in the notch 12 of the clamping ring 11, the boss 14 cooperates with the clamping ring 11 to form a sealing ring, the outer side of the clamping ring 11 abuts against the inner wall of the C-shaped pipe 13, the two ends of the opening of the C-shaped pipe 13 are fixed with fixed plates 15, and the fixed plates 15 are fixedly connected by bolts.

[0028] In the installation process, the snap ring 11 can be easily installed into the snap groove 10 through the gap 12 on the snap ring 11, and the end face of the snap ring 11 can abut against the side wall of the snap groove 10 to form an end face seal, which can prevent air or mixed gas from leaking at the connection and ensure the stability and efficiency of the combustion system. Then the C-shaped pipe 13 is sleeved on the air pipe 4, so that the inner side wall of the C-shaped pipe 13 abuts against the snap ring 11, and the sealing ring formed by the boss 14 on the inner side wall of the C-shaped pipe 13 and the gap 12 on the snap ring 11 further enhances the sealing performance of the connection, ensuring the integrity of the mixed gas during transmission. The pre-tightening force is applied to the fixed plate 15 through the bolt, ensuring that the inner side wall of the C-shaped pipe 13 abuts against the snap ring 11. The connection mode of the fixed plate 15 and the bolt allows the mixed gas pipe 6 to be easily disassembled and reinstalled, facilitating maintenance, inspection, and replacement of the mixed gas pipe 6. When disassembling the mixed gas pipe 6, the C-shaped pipe 13 can be easily removed from the air pipe 4 by loosening the bolt without damaging other components or structures. The outer diameter of the snap ring 11 is greater than that of the air pipe 4, and the outer side of the snap ring 11 abuts against the inner wall of the C-shaped pipe 13, which can reduce the friction between the inner side wall of the C-shaped pipe 13 and the air pipe 4, ensuring that the air outlet pipe 7 can rotate flexibly.

[0029] As shown in Figure 3 , 7 , the air inlet of the air pipe 4 is circumferentially arrayed with multiple helical guide plates 16. The inclined design of the guide plates 16 can guide the air entering the air pipe 4 to produce rotational motion. When this rotating air flow meets the gas in the air pipe 4, it can more effectively promote the mixing between the two, thereby improving the uniformity of the mixed gas and helping to reduce the amount of unburned gas and improve combustion efficiency.

[0030] As shown in Figure 1 , 2 , 7, the gas injection port 3 is three, and the diameter of the gas injection port 3 is 20mm. When one of the gas injection ports 3 cannot work normally due to various reasons (such as dust accumulation, blockage, etc.), the other two gas injection ports 3 can still continue to work, ensuring the normal operation of the combustion system. The diameter of 20mm of the gas injection port 3 can ensure sufficient gas flow, while avoiding the problem of excessive gas injection speed caused by excessively large injection port or insufficient gas flow caused by excessively small injection port. Moreover, the diameter of 20mm of the gas injection port 3 is not easy to block, reducing the frequency of cleaning and maintenance.

[0031] As shown in Figure 1 , the mixed gas pipe 6 is provided between the adjacent gas injection ports 3. Multiple mixed gas pipes 6 can ensure that the mixed gas is more uniformly distributed, so that the combustion can be more complete and uniform, and the uniform distribution of the mixed gas helps to form a stable flame structure, reducing the possibility of flame fluctuation and extinction.

[0032] As shown in Figures 3-5As shown, the end of the outlet pipe 7 is provided with a hinged rod 17, and a baffle 18 is hinged to the hinged rod 17 via a high-temperature resistant torsion spring. The baffle 18 can close the outlet pipe 7 under the torsional force of the torsion spring. The baffle 18 can automatically close the end of the outlet pipe 7 under the torsional force of the torsion spring. When gas discharge is not required, the baffle 18 can provide an effective seal to prevent gas leakage and simplify the closing operation of the outlet pipe 7. No additional closing device or manual intervention is required, which improves the convenience and efficiency of operation. The high-temperature resistant torsion spring and baffle 18 materials can ensure that stable performance and sealing effect are maintained in high-temperature environments. In the closed state, the baffle 18 can effectively block external impurities (such as dust, particulate matter, etc.) from entering the outlet pipe 7, preventing these impurities from accumulating in the pipe and causing blockage, helping to keep the outlet pipe 7 unobstructed, extending its service life, and reducing maintenance costs caused by cleaning blockages.

[0033] like Figure 4 As shown, a filter 19 is installed within the outlet pipe 7. Filter 19 further prevents tiny impurities (such as dust, fibers, and particulate matter) from entering the outlet pipe 7. If these impurities enter the pipe, they may deposit on the inner wall of the pipe, affect gas flow, or even cause pipe blockage. The installation of filter 19 ensures the purity of the gas within the outlet pipe 7 and reduces system failures or performance degradation caused by impurities.

[0034] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
