[0035] Please refer to Figures 1 to 5The embodiment provides a steam production device using waste methanol as fuel, which comprises a heating bin 10, a raw material tank 20, a first heating pipeline 50 and a second heating pipeline 60, the heating bin 10 is internally provided with a heating cavity, the heating cavity is sequentially divided into a combustion area 11, a first heating area 12, a second heating area 13 and a smoke exhaust area 14 from bottom to top, a smoke exhaust port 15 is arranged at the top of the heating bin 10, and the smoke exhaust port 15 is in communication with the smoke exhaust area 14; the raw material tank 20 is in communication with the heating bin 10 through a combustion pipeline 30, one end of the combustion pipeline 30 away from the raw material tank 20 is arranged in the combustion area 11, and the one end of the combustion pipeline 30 away from the raw material tank 20 is provided with an igniter 40; the first heating pipeline 50 is arranged in the second heating area 13, and both ends of the first heating pipeline are respectively connected with a first solution tank 70 and a second solution tank 80; the liquid temperature in the second solution tank 80 is higher than that in the first solution tank 70, and the first solution tank 70 and the second solution tank 80 are arranged on one side of the heating bin 10; the second heating pipeline 60 is arranged in the first heating area 12, one end of the second heating pipeline 60 is connected with the second solution tank 80, and the other end of the second heating pipeline 60 is connected with a steam using equipment 110 arranged on one side of the heating bin 10.

[0036] The middle sections of the first heating pipeline 50 and the second heating pipeline 60 are arranged in the first heating area 12 and the second heating area 13, and the first ends and the second ends of the first heating pipeline 50 and the second heating pipeline 60 are arranged outside the heating bin 10 to connect the first solution tank 70 and the second solution tank 80.

[0037] The steam production device using waste methanol as fuel provided by the embodiment aims to realize efficient utilization of waste methanol and effective generation of steam. Specifically, the core part of the device is the heating bin 10, which is internally provided with a heating cavity divided into multiple areas, including the combustion area 11, the first heating area 12, the second heating area 13 and the smoke exhaust area 14. Waste methanol is stored in the raw material tank 20 and is delivered to the combustion area 11 through the combustion pipeline 30. In the combustion area 11, the waste methanol is ignited by the igniter 40 after being mixed with air, and high-temperature combustion gas is generated. These gases flow upwards in the heating bin 10, first passing through the first heating area 12 and the second heating area 13, thereby transferring heat to the liquid flowing through the first heating pipeline 50 and the second heating pipeline 60.

[0038] The two ends of the first heating pipeline 50 are respectively connected to the first solution tank 70 and the second solution tank 80, wherein the liquid temperature in the second solution tank 80 is higher than that in the first solution tank 70, the second heating area 13 is preheating, and the first heating pipe in the second heating area 13 is preheated by using the residual heat. The second heating pipeline 60 is connected to the second solution tank 80 and the steam equipment 110, and is responsible for converting the high-temperature liquid into steam for the equipment. Through reasonable pipeline layout and heat transfer design, efficient production and full utilization of steam are ensured. The arrangement of the smoke exhaust area 14 ensures that the exhaust gas produced by combustion can be smoothly discharged, and through the arrangement of the smoke exhaust port 15, the pollution to the environment can be reduced.

[0039] By using waste methanol as fuel, the waste that would otherwise pollute the environment is fully utilized, production costs are reduced, and resource recycling is achieved. The reasonable layout of various functional modules in the device ensures efficient heat transfer and stable steam generation, thereby improving the continuity and reliability of the production process. In addition, the high temperature and high pressure characteristics of the steam make it have higher value in industrial applications, and it can be directly used to drive equipment or perform heat exchange.

[0040] Please refer to Figures 1 to 5 In some embodiments, a steam production device using waste methanol as fuel further comprises a steam-water separation tank 90, the end of the second heating pipeline 60 away from the second solution tank 80 is connected to the steam-water separation tank 90, the connection position of the second heating pipeline 60 and the steam-water separation tank 90 is lower than the connection position of the second heating pipeline 60 and the second solution tank 80, and the steam-water separation tank 90 is connected to the steam equipment 110 through a steam pipeline 100.

[0041] In this embodiment, the functionality and efficiency of the steam production device using waste methanol as fuel are further enhanced, especially by adding the design of the steam-water separation tank 90 to optimize the quality and use efficiency of the steam. The steam-water separation tank 90 is arranged at the end of the second heating pipeline 60 and connected to the distal end of the second heating pipeline 60, which is lower than the connection point with the second solution tank 80, ensuring that when the steam and liquid mixture flow into the steam-water separation tank 90, gravity helps to separate the steam from the unevaporated liquid. The steam rises in the steam-water separation tank 90, while the condensed water sinks due to gravity and eventually accumulates at the bottom of the steam-water separation tank 90, ensuring the dryness and heat of the output steam. The separated high-quality steam is transported to the steam equipment 110 through the steam pipeline 100. Further, the bottom of the steam-water separation tank 90 can be provided with a drain pipe or a circulation pipeline connected to the first solution tank 70 or the second solution tank 80, so that the water at the bottom can be returned to the first solution tank 70 or the second solution tank 80 through the drain pipe or the circulation pipeline, ensuring maximum utilization of resources.

[0042] Through the scheme of the present embodiment, not only the purity of the steam is improved, but also the influence of the liquid on the steam-using equipment 110 is reduced, the damage of the equipment caused by the liquid is prevented, and the service life of the equipment is prolonged. In addition, by properly designing and optimizing the steam-water separation tank 90, the temperature and pressure of the steam can be further improved, making it more suitable for industrial applications. The establishment of the reflux system enables the non-evaporated liquid to be utilized again, reducing resource waste and reducing production costs.

[0043] Referring to Figures 1 to 5 In some embodiments, a water pump 120 is arranged on the first heating pipeline 50, and the water pump 120 is arranged outside the heating cabin 10.

[0044] In the present embodiment, the water pump 120 is arranged outside the heating cabin 10, which can effectively avoid the damage of high-temperature steam to the pump body, facilitate maintenance and repair, and reduce the risk of failure. The water pump 120 monitors the liquid flow in real time to ensure that the liquid circulation between the first solution tank 70 and the second solution tank 80 is unobstructed, and the liquid flow is more stable, thereby improving the heat exchange efficiency and ensuring that the liquid always remains in the optimal temperature range during the heating process, further improving the yield and quality of the steam.

[0045] Referring to Figures 1 to 5 In some embodiments, a metering pump 130 is arranged on the combustion pipeline 30, and the metering pump 130 is arranged outside the heating cabin 10.

[0046] In the present embodiment, the metering pump 130 is arranged outside the heating cabin 10, which not only facilitates operation and maintenance, but also effectively reduces the influence of high-temperature environment on the pump body and its components. The metering pump 130 adjusts the flow of waste methanol to dynamically adjust the amount of methanol entering the combustion area 11 according to actual needs, thereby optimizing the combustion efficiency, reducing the emission of unburned methanol, and reducing environmental pollution. Further, the metering pump 130 is equipped with a flow sensor to monitor the flow change in real time, ensuring that the system can maintain a stable combustion state under different loads. When the system needs to operate at high load, the metering pump 130 can quickly increase the flow to ensure the sufficiency of combustion; when operating at low load, the metering pump 130 can timely reduce the flow to avoid resource waste. Through this design, the energy efficiency of the entire combustion system is improved, and the operation risk is reduced, improving the safety and reliability of the equipment.

[0047] In combination with the application of the water pump 120 and the metering pump 130, the device provided by the present embodiment can realize precise control of the flow, ensuring that the required heat source and steam can be stably supplied under different working conditions, and maximizing the energy utilization efficiency of the entire system.

[0048] Referring to Figures 1 to 5In some embodiments, the first solution tank 70 is located on one side above the second solution tank 80.

[0049] In this embodiment, the first solution tank 70 is placed on one side above the second solution tank 80, making full use of the principle of gravity to ensure that the liquid can flow smoothly from the first solution tank 70 into the second solution tank 80 during the flow process. Through the action of gravity, the liquid in the first solution tank 70 can flow downward more effectively after being heated, reducing the energy consumption of the pump and the dependence on external power. In addition, this layout also facilitates the heat exchange of the liquid, improving the thermal efficiency. During the heating process, the liquid in the first solution tank 70 is heated to a certain temperature and then flows into the second solution tank 80 for further heating, thereby improving the thermal energy utilization efficiency of the entire system and ensuring high output and high quality of the steam.

[0050] Please refer to Figures 1 to 5 In some embodiments, the part of the first heating pipeline 50 located in the second heating area 13 is arranged in a spiral downward manner. That is, the cross section of the part of the first heating pipeline 50 located in the second heating area 13 is S-shaped to increase the heating time.

[0051] In this embodiment, the spiral shape design of the first heating pipeline 50 increases the residence time of the fluid in the first heating pipeline 50, thereby improving the heat exchange efficiency. Specifically, in the spiral downward pipeline, the fluid constantly changes direction during the flow process, increasing the contact time with the heat source, so that the heat can be more fully transferred to the fluid. In addition, the spiral-shaped pipeline design can also effectively reduce the turbulent loss of the fluid, maintaining the stability of the fluid flow. Therefore, the fluid can obtain the required temperature under lower energy consumption conditions when passing through the first heating pipeline 50.

[0052] In the steam production process, the scheme provided in this embodiment can perform efficient heat exchange to ensure that the temperature and pressure of the steam reach the expected standard, providing a stable heat source for subsequent industrial use. At the same time, the S-shaped pipeline layout can also effectively utilize space, reducing the equipment footprint and optimizing the overall equipment design.

[0053] Please refer to Figures 1 to 5 In some embodiments, the part of the second heating pipeline 60 located in the first heating area 12 is arranged in a spiral downward manner. That is, the cross section of the part of the second heating pipeline 60 located in the first heating area 12 is S-shaped to increase the heating time.

[0054] In this embodiment, the portion of the second heating pipeline 60 in the first heating area 12 adopts a similar spiral descending design as the first heating pipeline 50. This S-shaped cross-section pipeline layout is also aimed at improving the efficiency of the heat exchange process. The second heating pipeline 60 is responsible for transporting the high-temperature liquid flowing out of the second solution tank 80 to the steam-using equipment 110, and it is necessary to ensure that the liquid can fully absorb heat in the heating area. The spiral descending pipeline design increases the contact time of the liquid with the heat source, allowing the heat to be better transferred to the liquid, thereby increasing the outlet temperature of the liquid. At the same time, the spiral shape of the pipeline is also beneficial to reducing the turbulent loss of the fluid and maintaining the stability of the flow.

[0055] In addition, the spiral design of the second heating pipeline 60 not only improves the heat exchange efficiency, but also effectively utilizes space, making the entire device more compact. This compact design not only reduces the equipment footprint, but also facilitates the installation and maintenance of the equipment. Compared with linearly arranged pipelines, spiral pipelines can better adapt to the space limitations inside the heating chamber and make full use of existing space resources.

[0056] Please refer to Figures 1 to 5 In some embodiments, the width of the smoke exhaust area 14 near the second heating area is greater than the width of the smoke exhaust area 14 near the smoke exhaust port 15.

[0057] In this embodiment, the tapered design of the smoke exhaust area 14 is beneficial to guiding and optimizing the flow of flue gas. Specifically, in the second heating area 13, due to the release of heat, the flue gas temperature is high and the volume is large, so a wider space is needed to accommodate and circulate; as the flue gas flows towards the smoke exhaust port 15, the temperature gradually decreases and the volume also decreases accordingly. This tapered width adjustment helps maintain the stability of the flue gas flow, avoiding phenomena such as turbulence or disorder, ensuring that the flue gas can be smoothly exhausted. At the same time, it can minimize the energy loss of the flue gas during the exhaust process, improve the overall energy utilization efficiency, and reduce the manufacturing and operating costs.

[0058] Further, the following examples can be developed in combination with the above-mentioned solutions:

[0059] Methanol enters the combustion area 11 of the heating chamber 10 through the metering pump 130 and is burned, generating heat to heat the second heating pipeline 60. The hot gas rises to the first heating pipeline 50, and finally the flue gas enters the smoke exhaust port 15 from the smoke exhaust area 14; pure water enters the first heating pipeline 50 for preheating, and then returns to the second solution tank 80. The hot water from the second solution tank 80 enters the second heating pipeline 60 after heating to become water vapor, which then enters the steam-water separation tank 90 for gas-liquid separation. The gas phase is steam, which is then sent to the steam-using equipment 110, completing the full utilization of methanol heat energy.

[0060] Further, the methanol feed adopts an imported metering pump 130 to accurately meter the methanol feed quantity and stably control the flow.

[0061] The ignition device 40 is placed at the bottom of the second heating pipeline 60, and heat is gradually added to the water in the second heating pipeline 60 and the first heating pipeline 50 from bottom to top.

[0062] The heat of the flue gas is fully utilized, the low-temperature flue gas heats the normal-temperature water and then returns to the second solution tank 80, and the hot water is heated to obtain steam of a set pressure.

[0063] The first heating pipeline 50, the second heating pipeline 60 and the ignition device 40 are arranged in sequence from top to bottom, and the thermal efficiency is greatly improved and is more than 90%.

[0064] The steam-water separation tank 90 can realize adjustment of the steam pressure and steam-water separation, avoids water from entering the steam pipeline 100 and reduces gas-liquid entrainment.

[0065] The methanol of the device is recycled methanol, and the content of the methanol is greater than 90%, so that the requirement for the methanol is not high.

[0066] Compared with the prior art, the device has the beneficial effects that:

[0067] The device comprises a heating bin 10, a raw material tank 20, a first heating pipeline 50 and a second heating pipeline 60.

[0068] The device realizes accurate control of the flow, can stably supply the required heat source and steam under different working conditions, maximally improves the energy utilization efficiency of the whole system, and effectively improves the heat exchange efficiency through the spiral design of the first heating pipeline 50 and the second heating pipeline 60.

[0069] The steam production device with waste methanol as fuel has remarkable advantages in aspects of realizing recycling of waste resources, improving heat energy conversion efficiency, producing high-quality steam, reducing environmental load and the like, and provides an efficient and environment-friendly steam supply solution for industrial production.
