This leads to troublesome maintenance and assembly process, and is very inconvenient during processing; there are many connection points between the components, which increases the probability of gas leakage in the combustion system, and the air tightness of the combustion system is poor, which is prone to "spitting fire" phenomenon;

[0005] 2. When using an air booster, it is easy for the air pressure inside the air booster to be too high when the air consumption is small, which poses certain safety hazards in actual use.

DETAILED DESCRIPTION

[0034] The present invention is further described below in conjunction with embodiments, which are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, other embodiments obtained by ordinary technicians in the field without creative work are all within the scope of protection of the present invention.

[0035] Embodiment 1

[0036] See the instruction manual Figure 1-5The present embodiment discloses a methyl ester fuel combustion system, including a burner, an oil and gas two-fluid nozzle 101, a high-pressure ignition package, a cup-type oil and gas controller 103, a pressure reducing valve 104 and an air booster 105, wherein the high-pressure ignition package is installed on the side wall of the burner, the oil and gas two-fluid nozzle 101 is installed at the bottom of the burner, the oil and gas two-fluid nozzle 101 is connected to the cup-type oil and gas controller 103, the air booster 105 is connected to the cup-type oil and gas controller 103 through the pressure reducing valve 104, the air booster 105 is connected to a circuit conversion module 106, and the circuit conversion module 106 is used to convert alternating current into direct current; an air pressure sensor 107 and a safety solenoid valve 108 are provided on the air booster 105, and the safety solenoid valve 108 is connected to the air pressure sensor 107, and the air pressure sensor 107 is used to detect the air pressure inside the air booster 105. When the air pressure value inside the air booster 105 is greater than the preset pressure value, the safety solenoid valve 108 can be opened to release the pressure.

[0037] Among them, the working principle of the circuit conversion module 106 is as follows: first, the alternating current is rectified by a diode, and the rectification can convert the positive and negative bidirectional electricity into single-phase electricity; the current is filtered by a capacitor to convert the half-wave voltage into a stable direct current voltage, which can become direct current after filtering. At this time, the voltage value is relatively high, and a voltage stabilizer is required to stabilize the direct current to the required voltage. Its internal circuit will not be described here one by one.

[0038] The present invention is mainly composed of a burner head, an oil and gas two-fluid nozzle 101, a high-pressure ignition package, a cup-type oil and gas controller 103, a pressure reducing valve 104 and an air booster 105. In actual use, the cup-type oil and gas controller 103 is used to control the oil and gas mixing ratio; and the circuit conversion module 106 is used to convert 220V AC power into DC power, and the air pressure sensor 107 and the safety solenoid valve 108 are used to ensure the safety of the air booster 105 during use. When the air pressure value inside the air booster 105 is greater than the preset pressure value, the safety solenoid valve 108 can be opened to release the pressure; in this way, it is safer in actual use, and starting the air booster 105 with DC power can make it more stable when starting and running.

[0039] The cup-type oil and gas controller 103 includes a cup body component 4 and a cup cover component 1 connected to the cup body component 4 in a detachable connection manner;

[0040] The cup body assembly 4 includes a cup body 5, an air circuit assembly 6 and an oil circuit assembly 15. A filter screen 7 is arranged in the cup body 5. The air circuit assembly 6 includes an adjusting rod Ⅰ10 and an air pipe 11 with a "T"-shaped structure. The air pipe 11 has an air inlet 12, an air outlet 13 and an adjusting port Ⅰ14. The air inlet 12, the air outlet 13 and the adjusting port Ⅰ14 are connected to each other. The air pipe 11 has a conical cavity Ⅰ. The large end of the conical cavity Ⅰ is connected to the adjusting port Ⅰ14, and the small end is connected to the air outlet 13. The air inlet 12 is connected to the side wall of the conical cavity Ⅰ. One end of the adjusting rod Ⅰ10 has a conical portion Ⅰ that can cooperate with the conical cavity Ⅰ. The adjusting rod Ⅰ10 is arranged in the adjusting port Ⅰ14 through a thread. After the adjusting rod Ⅰ10 is rotated, the adjusting rod Ⅰ10 can enter and exit the adjusting port Ⅰ14, thereby realizing the adjustment of the air volume;

[0041] The oil circuit assembly 15 includes an adjusting rod Ⅱ16 and an oil pipe 17 in a "I"-shaped structure. The oil pipe 17 has an oil inlet 18, an oil outlet 19 and an adjusting port Ⅱ1901. The oil inlet 18, the oil outlet 19 and the adjusting port Ⅱ1901 are connected to each other. The oil pipe 17 has a tapered cavity Ⅱ21. The large end of the tapered cavity Ⅱ21 is connected to the adjusting port Ⅱ1901, and the small end is connected to the oil outlet 19. The oil inlet 18 is connected to the side wall of the tapered cavity Ⅱ21. One end of the adjusting rod Ⅱ16 has a tapered portion Ⅱ22 that can cooperate with the tapered cavity Ⅱ21. The adjusting rod Ⅱ16 is arranged in the adjusting port Ⅱ1901 through a thread. After the adjusting rod Ⅱ16 is rotated, the adjusting rod Ⅱ16 can enter and exit the adjusting port Ⅱ1901, thereby realizing the adjustment of the oil amount.

[0042] The air pipe 11 and the oil pipe 17 are connected to the lower end of the cup body 5, and the oil inlet 18 arranged on the oil pipe 17 is connected to the cup body 5. The axis of the regulating port Ⅰ14 of the air pipe 11 and the axis of the regulating port Ⅱ1901 of the oil circuit are parallel to each other; the regulating rod Ⅰ10 and the regulating rod Ⅱ16 are connected by a linkage assembly 23.

[0043] Further optimized, the oil pipe 17 and the air pipe 11 are integrally formed with the cup body 5 .

[0044] In actual use, the filter screen 7 can filter out mechanical impurities in the methyl ester fuel, preventing the mechanical impurities in the methyl ester fuel from clogging the pipelines in the combustion system, and can effectively improve the stability of the combustion system.

[0045] More importantly, in this embodiment, the oil pipe 17 and the air pipe 11 are integrally formed with the cup body 5, and can be directly processed by casting in actual processing, and the processing technology is simpler. In addition, the air pipe 11 has an air inlet 12, an air outlet 13 and an adjustment port I 14, and the oil pipe 17 has an oil inlet 18, an oil outlet 19 and an adjustment port II 1901. The air pipe 11 and the oil pipe 17 are connected to the lower end of the cup body 5, and the oil inlet 18 set on the oil pipe 17 is connected to the cup body 5; the adjustment port Ⅰ14 and the adjustment port Ⅱ1901 are installed with the adjustment rod Ⅰ10 and the adjustment rod Ⅱ16, and the adjustment rod Ⅰ10 and the adjustment rod Ⅱ16 are connected by the linkage assembly 23. In this way, the oil-gas mixture ratio can be adjusted by rotating the adjustment rod Ⅰ10, which is more convenient to use. At the same time, the present invention adopts an integrated structure, which can effectively reduce the connection points, reduce the leakage points in the pipeline, reduce the probability of gas leakage, and ensure the air tightness of the combustion system. At the same time, it also makes it more convenient during installation and improves the installation efficiency.

[0046] In this way, in actual use, by rotating the adjusting rod Ⅰ10, the adjusting rod Ⅰ10 can enter and exit the adjusting port Ⅰ14, so that the conical portion Ⅰ set on the adjusting rod Ⅰ10 cooperates with the conical cavity Ⅰ to adjust the gas volume of the gas outlet 13; similarly, the oil volume of the oil outlet 19 can be adjusted by adjusting the adjusting rod Ⅱ16; and, the linkage control of the gas outlet and the oil outlet is realized through the interface of the linkage component 23, so the purpose of oil-gas linkage control can be achieved in actual use.

[0047] Among them, the cup cover assembly 1 includes a cover body 2 and a solenoid valve body 3, the solenoid valve body 3 passes through the cover body 2 and is fixedly connected to the cover body 2, the feed port 37 of the solenoid valve body 3 extends out of the cover body 2, and the discharge port 38 of the solenoid valve body 3 is located inside the cover body 2.

[0048] Among them, in actual use, the feed port 37 of the solenoid valve body 3 is connected to the methyl ester fuel tank 102, and after the air enters the oil-gas two-fluid nozzle 101, a negative pressure is formed in the oil-gas two-fluid nozzle 101, and the methyl ester fuel oil in the methyl ester fuel tank 102 is sucked out under the action of the negative pressure, thereby realizing the supply of methyl ester fuel oil. In actual use, the methyl ester fuel in the methyl ester fuel tank 102 enters the cup body 5 from the feed port 37 of the solenoid valve body 3, flows through the oil inlet 18 after being filtered, and enters the oil-gas two-fluid nozzle 101 from the oil outlet 19; the air pressurized by the air compressor 105 passes through the air inlet 12 and the air outlet 13 on the air pipe 11 in turn and enters the oil-gas two-fluid nozzle 101.

[0049] More importantly, the oil pipe 17 and the air pipe 11 are integrally formed with the cup body 5, which is not only simpler in production and processing technology, but also reduces the connection points between components, reduces the leakage points in the pipeline, reduces the probability of leakage, and ensures the airtightness of the combustion system; at the same time, it also makes installation more convenient and improves installation efficiency; at the same time, it can avoid the "fire spitting" phenomenon due to leakage, making the system more stable when in use.

[0050] In this embodiment, the solenoid valve body 3 is a normally closed solenoid valve, which opens when powered on and closes to cut off the oil circuit when powered off.

[0051] When in use, negative pressure is formed in the cup-type oil and gas controller 103. Thus, after the fire is turned off, the fuel in the oil and gas two-fluid nozzle 101 can be sucked out by the cup-type oil and gas controller 103, thereby avoiding the coking of the residual fuel in the oil and gas two-fluid nozzle 101 under high temperature, and preventing the oil and gas two-fluid nozzle 101 from being coked and blocked, thereby ensuring the stable operation of the system and further improving the stability of the system.

[0052] In the actual use of the present invention, the high voltage ignition package is connected to the power supply.

[0053] Embodiment 2

[0054] This embodiment is further optimized on the basis of the first embodiment. In this embodiment, the cup body 5 and the cover body 2 are connected via internal threads or external threads.

[0055] It is further defined that an external thread 27 is provided at the opening of the cover body 2 , and an internal thread 28 is provided at the opening of the cup body 5 , and the cup body 5 and the cover body 2 are connected via the internal thread 28 and the external thread 27 .

[0056] In this way, the assembly of the cup body 5 and the cover body 2 is simpler in actual use, which can effectively improve the assembly efficiency.

[0057] For further optimization, the opening of the cup body 5 is provided with a stepped platform 29, the internal thread 28 is provided on the side of the stepped platform 29, a card groove 30 is provided on the end face of the stepped platform 29, a sealing gasket 31 is provided in the card groove 30, and after the cup body 5 and the cover body 2 are screwed together, the cover body 2 is tightly pressed on the sealing gasket 31.

[0058] In this way, the provided card slot 30 can prevent the sealing gasket 31 from shifting during the rotation of the cover body 2; and the provided sealing gasket 31 can make the connection between the cup body 5 and the cover body 2 tighter, so that after the cup body 5 and the cover body 2 are screwed together, the cup body 5 and the cover body 2 form a sealing structure, thereby ensuring that negative pressure is formed inside the cup body 5 and the cover body 2 during use.

[0059] Further optimization, in order to facilitate installation, the side wall of the cup body 5 is provided with a support ear 32, and the support ear 32 is provided with a mounting hole 33, and the mounting hole 33 is a strip hole. In this way, it is more convenient to install the cup body 5, and the provided strip hole can ensure that the position of the cup body 5 can be finely adjusted during the installation process.

[0060] The filter screen 7 includes a bracket 8 and a filter screen 9 arranged on the bracket 8 . A supporting protrusion 34 is arranged on the inner wall of the cup body 5 , and the bracket 8 of the filter screen 7 is placed on the supporting protrusion 34 .

[0061] In this way, it is convenient to install the filter screen 7 in actual use, and the positioning groove can ensure that the filter screen 7 will not rotate after installation.

[0062] In actual use, the end of the adjusting rod Ⅰ10 is connected with a handle 35, so that it is more convenient to adjust the oil-gas mixture ratio.

[0063] Among them, it needs to be further explained that the linkage assembly 23 includes a driving wheel 24 and a driven wheel 25, the driving wheel 24 is a full-tooth gear, and the driven wheel 25 is provided with three-quarter meshing teeth 26 on the side of the wheel; the driving wheel 24 is installed on the adjusting rod Ⅰ10, and the driven wheel 25 is installed on the adjusting rod Ⅱ16, and the driving wheel 24 and the driven wheel 25 can mesh with each other.

[0064] In this way, since three-quarters of the meshing teeth 26 are provided on the side of the upper wheel of the driven wheel 25, the driving wheel 24 can be limited. In this way, in actual use, the driving wheel 24 and the driven wheel 25 can be prevented from being separated. The other quarter of the driven wheel 25 is not provided with meshing teeth 26, so that the driven wheel 25 can only rotate within 270°, which can reduce the setting of the limiting device and simplify its structure.

[0065] In actual use, at least one sealing ring 36 is provided between the adjusting rod Ⅰ10 and the adjusting port Ⅰ14; at least one sealing ring 36 is provided between the adjusting rod Ⅱ16 and the adjusting port Ⅱ1901; the provided sealing ring 36 can further prevent air leakage or oil leakage.

[0066] As a further optimization, a boss 20 with a polygonal structure is provided at the upper end of the cover body 2; thus, it is more convenient in the actual assembly process, and the boss 20 can be clamped with a wrench and then rotated.
