DETAILED DESCRIPTION

[0031] In order to make it easier to understand the structure of the present invention and the functional features and advantages that can be achieved, the preferred embodiments of the present invention are described in detail with reference to the drawings as follows:

[0032] Embodiment 1:

[0033] like Figures 1 to 5 As shown, the present invention provides a high-efficiency energy-saving combustion control system for a boiler vehicle, comprising a mounting platform 1, characterized in that it also includes:

[0034] An air supply optimization component is disposed on the mounting platform 1. The air supply optimization component is connected to a fuel pipe 2. The air supply optimization component fully mixes the gas in the fuel pipe 2 with the external air to ensure high-efficiency combustion of the fuel;

[0035] A combustion chamber 3, which is disposed on the mounting platform 1 and is connected to the air supply optimization component via an air pipeline 4;

[0036] A waste heat recovery component is disposed on the combustion chamber 3 , and the waste heat recovery component recovers the high-temperature gas in the combustion chamber 3 and discharges it back into the combustion chamber 3 .

[0037] First, the air supply optimization component will inhale air from the outside and fully mix it with the gas in the fuel pipe 2 to ensure that the gas and air are fully mixed, so that the fuel can burn more fully and efficiently. Then, the mixed gas and air will enter the combustion chamber 3 through the gas pipeline 4, and burn in the combustion chamber 3 to produce high-temperature gas. In order to prevent these high-temperature gases from being wasted, the system is also equipped with a waste heat recovery component, which will recover these high-temperature gases and return them to the combustion chamber 3 for secondary utilization. This not only improves the utilization rate of thermal energy, but also reduces energy waste. The entire process, from the mixing of air and gas, to the efficient combustion of the combustion chamber 3, and then to the recovery and utilization of waste heat, is closely linked, and ultimately achieves the goal of efficient combustion and energy saving, making the boiler vehicle more economical and environmentally friendly.

[0038] Embodiment 2:

[0039] like Figures 1 to 5As shown, in combination with the technical solution of Example 1, in this technical solution, the air supply optimization component includes:

[0040] The installation bin 5 has two air inlet holes on its side wall, a partition 6 is fixedly mounted on the inner wall of the installation bin 5, the partition 6 divides the installation bin 5 into a preliminary mixing chamber 7 and a sufficient mixing chamber 8, a gas pipeline 4 is mounted on the outer wall of the installation bin 5, the gas pipeline 4 is connected to the sufficient mixing chamber 8, and one end of the fuel pipe 2 is connected to the preliminary mixing chamber 7;

[0041] Inlet pipes 9, the number of the inlet pipes 9 is two and they are fixedly mounted on the two air inlet holes respectively, and inlet fans 10 are rotatably mounted in the two air inlet pipes 9;

[0042] A mixing tube 11, wherein the number of the mixing tubes 11 is several and they are fixedly installed on the partition 6, one end of the mixing tube 11 is located in the preliminary mixing chamber 7, and the other end of the mixing tube 11 is located in the full mixing chamber 8;

[0043] The air intake fan 12 is rotatably mounted on the partition plate 6 located on one side of the sufficient mixing chamber 8.

[0044] First, air will enter the installation chamber 5 through two air intake pipes 9. An air intake fan 10 is installed in the air intake pipe 9. When the fan rotates, the air intake speed will be accelerated, allowing the air to enter the preliminary mixing chamber 7 more efficiently. At the same time, the fuel pipe 2 will transport the gas to the preliminary mixing chamber 7, where the air and gas will be mixed for the first time. Then, the mixing pipe 11 will transport the preliminary mixed gas from the preliminary mixing chamber 7 to the fully mixing chamber 8. In the fully mixing chamber 8, the air intake fan 12 will further stir the gas to make the air and gas mix more evenly. Finally, the mixed gas will be sent out through the gas pipeline 4 and enter the combustion chamber 3 for combustion.

[0045] Furthermore, a mounting rod 13 is fixedly mounted on the inner wall of the air intake pipe 9, a first motor 14 is fixedly mounted on the mounting rod 13, and a rotating shaft 15 is fixedly mounted between the output shaft of the first motor 14 and the air intake fan 10. When the motor is started, the output shaft drives the rotating shaft 15 to rotate, thereby rotating the air intake fan 10, so that the air intake fan 10 can quickly inhale external air and accelerate the air into the preliminary mixing chamber 7. The core of the whole process is to drive the air intake fan 10 through the motor to ensure that the air can enter the system stably and efficiently, and provide sufficient airflow support for the subsequent mixing of air and gas.

[0046] Furthermore, a plurality of mixing tubes 11 are evenly distributed in an array on the partition 6, and a plurality of ventilation pipes are provided on the mixing tubes 11 along the direction from the preliminary mixing chamber 7 to the fully mixing chamber 8. The mixing tubes 11 are neatly arranged on the partition 6, extending from the preliminary mixing chamber 7 to the fully mixing chamber 8. Several ventilation pipes are provided on each mixing tube 11. These ventilation pipes are distributed along the direction of the mixing tubes 11, which can allow the gas to be continuously dispersed and mixed during the flow process. After the air and the gas are mixed for the first time in the preliminary mixing chamber 7, these gases will enter the fully mixing chamber 8 through the mixing tubes 11. The ventilation pipes will allow the gas to be further mixed during the flow process, ensuring that the air and the gas can fully contact and achieve a more uniform mixing effect. In this way, the gas is fully mixed before entering the combustion chamber 3, laying the foundation for efficient combustion.

[0047] Furthermore, a mounting seat 16 is fixedly mounted on the partition 6, a second motor 17 is fixedly mounted in the mounting seat 16, and a rotating shaft 18 is fixedly mounted between the output shaft of the second motor 17 and the air intake fan 12. When the second motor 17 is started, the output shaft drives the rotating shaft 18 to rotate, thereby driving the air intake fan 12 to rotate. When the air intake fan 12 rotates, the gas in the preliminary mixing chamber 7 can be quickly sucked into the sufficient mixing chamber 8, and the gas is further stirred in the sufficient mixing chamber 8, so that the air and gas are mixed more evenly.

[0048] Furthermore, several layers of combustion seats 19 are fixedly installed in sequence from top to bottom in the combustion chamber 3, and one end of the gas pipeline 4 away from the installation bin 5 is interconnected with the combustion seat 19. Heating pipes 20 are arranged above the several layers of combustion seats 19. The heating pipes 20 are fixedly installed to the side walls of the combustion chamber 3 through connecting frames, and the several layers of heating pipes 20 are interconnected. Several layers of combustion seats 19 are installed from top to bottom in the combustion chamber 3, and the gas pipeline 4 will connect these combustion seats 19 so that the mixed gas can be evenly distributed on each layer of combustion seats 19 for combustion. Heating tubes 20 are also installed above each layer of combustion seats 19. These heating tubes 20 are fixed to the side walls of the combustion chamber 3 through connecting frames, and the heating tubes 20 are also interconnected. When the gas burns on the combustion seat 19, the heat generated will be transferred to the heating tubes 20, and the heating tubes 20 will then distribute the heat evenly to the entire combustion chamber 3, ensuring that the combustion process is more stable and efficient. In this way, the fuel not only burns more fully, but also makes full use of the heat energy generated by the combustion to achieve energy-saving and high-efficiency effects. The core of the whole process is to achieve efficient combustion and maximize the utilization of heat energy through the coordination of layered combustion and heating tubes 20.

[0049] Furthermore, an air compressor 21 is fixedly installed at the connection between the installation chamber 5 and the gas pipeline 4, and the air compressor 21 introduces the gas in the sufficient mixing chamber 8 into the gas pipeline 4. When the air compressor 21 is started, it compresses the gas in the sufficient mixing chamber 8, and then quickly transports it to the combustion chamber 3 through the gas pipeline 4. In this way, the gas can not only quickly enter the combustion chamber 3, but also maintain a stable pressure during the transportation process, ensuring that the combustion process in the combustion chamber 3 is more efficient and stable.

[0050] Furthermore, the waste heat recovery component includes:

[0051] A waste heat return pipe 22, one end of which penetrates and is connected to the top wall of the combustion chamber 3, and the other end of which is respectively connected to a plurality of waste heat return auxiliary pipes 23, which respectively penetrate the side walls of the combustion chamber 3 and correspond to a plurality of layers of heating pipes 20;

[0052] The pump body 24 is disposed on the waste heat reflux pipe 22 , and the pump body 24 is used to introduce the high-temperature gas in the combustion chamber 3 into the waste heat reflux pipe 22 .

[0053] One end of the waste heat return pipe 22 is connected to the top of the combustion chamber 3, and the other end is divided into several waste heat return auxiliary pipes 23. These auxiliary pipes pass through the side walls of the combustion chamber 3 and are connected to the heating pipes 20 of each layer. In order to allow the high-temperature gas to flow smoothly, a pump body 24 is also installed on the waste heat return pipe 22. The pump body 24 will draw the high-temperature gas in the combustion chamber 3 into the waste heat return pipe 22, and then transport it to the heating pipes 20 of each layer through the waste heat return auxiliary pipe 23. In this way, the heat in the high-temperature gas can be reused by the heating pipe 20, which not only improves the utilization efficiency of thermal energy, but also reduces energy waste. The core of the whole process is to recover and reuse the waste heat in the combustion chamber 3 through the cooperation of the pump body 24 and the pipeline, so as to achieve energy-saving and high-efficiency effects.

[0054] The working principle of this application for a high-efficiency energy-saving combustion control system for a boiler vehicle:

[0055] First, the air supply optimization component will inhale air from the outside and accelerate the air flow through the air intake fan 10 in the air intake pipe 9. The air and the gas transported by the fuel pipe 2 will be mixed for the first time in the preliminary mixing chamber 7 of the installation bin 5, and then enter the full mixing chamber 8 through the mixing pipe 11. They will be further mixed evenly under the stirring of the air intake fan 12 to ensure that the gas and air are in full contact. Then, the air compressor 21 will pressurize the mixed gas and transport it to the combustion chamber 3 through the gas pipeline 4. There are several layers of combustion seats 19 in the combustion chamber 3. The gas will burn on these combustion seats 19. A heating pipe 20 is also installed above the combustion seat 19 to evenly distribute heat to quickly heat the water. The high-temperature gas generated by the combustion will be recovered by the waste heat recovery component. The waste heat return pipe 22 and the pump body 24 will send these high-temperature gases back to the combustion chamber 3 and reuse them through the heating pipe 20 to avoid heat waste. The whole process, from the mixing and combustion of air and gas to the waste heat recovery, is closely linked, which not only improves the combustion efficiency, but also achieves the goal of energy saving and environmental protection, making the boiler vehicle run more efficiently and stably.
