Description

Technical Field

[0001] This utility model relates to the field of methanol furnace technology, and more specifically to a methanol furnace gasification system. Background Technology

[0002] Existing methanol combustion furnaces typically employ a single-stage gasification design, meaning methanol undergoes only one gasification process before entering the combustion stage. However, due to incomplete gasification, some methanol still participates in combustion in a liquid or semi-gaseous state, leading to low combustion efficiency and significant energy waste. Furthermore, incompletely gasified methanol can easily produce harmful gases such as carbon monoxide and formaldehyde during combustion, posing safety hazards and potentially causing environmental pollution. In addition, the participation of semi-gaseous or liquid methanol in combustion can cause flame instability, resulting in fluctuating flame size and negatively impacting the user experience. To improve combustion efficiency, reduce harmful gas emissions, and enhance safety, a system capable of achieving complete methanol gasification is needed. This system should optimize the gasification process to ensure that methanol is fully gasified before entering the combustion stage. Utility Model Content

[0003] In view of this, the present invention provides a methanol furnace gasification system.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A methanol gasification system includes: a methanol storage unit for storing liquid methanol; a conveying unit employing an electromagnetic pump for quantitatively conveying the liquid methanol from the methanol storage unit to a primary gasification unit; a primary gasification unit including a gasification pipe and an auxiliary heating structure disposed outside the gasification pipe, wherein the liquid methanol is heated by the auxiliary heating structure inside the gasification pipe to form a semi-gaseous methanol mixture; a secondary gasification unit including a secondary gasification chamber and a stainless steel heating plate attached to the bottom of the secondary gasification chamber, wherein the semi-gaseous methanol mixture is completely gasified in the secondary gasification chamber by heating by the stainless steel heating plate; a combustion unit including a burner head connected to the secondary gasification unit and a burner panel disposed outside the burner head for receiving and burning the completely gasified methanol; and a control unit electrically connected to the conveying unit and the stainless steel heating plate for controlling the operating status of the conveying unit and the stainless steel heating plate.

[0005] In a preferred embodiment, the vaporization pipe is a ring-shaped hollow structure and is arranged around the outer periphery of the furnace head to extend the heating path of liquid methanol and improve the primary vaporization efficiency.

[0006] In the preferred embodiment, the auxiliary heating structure surrounds the outside of the burner head, which can absorb the heat during methanol combustion, and the auxiliary heating structure is fitted to the outer wall of the gasification pipe to provide a uniform heat source to the gasification pipe.

[0007] In a preferred embodiment, a connecting pipe extends from the bottom of the vaporization pipe and is connected to the secondary vaporization chamber to stably transport the semi-gaseous methanol mixture formed by the primary vaporization to the secondary vaporization chamber.

[0008] In a preferred embodiment, the stainless steel heating plate is positioned at the bottom of the secondary vaporization chamber, so that the secondary vaporization heating area covers the main heating area at the bottom of the secondary vaporization chamber.

[0009] In a preferred embodiment, an igniter is provided on the burner side of the combustion unit. The igniter is electrically connected to the control unit and is used to automatically ignite the gaseous methanol output from the secondary gasification unit.

[0010] In a preferred embodiment, the control unit is used to perform pulsed or continuous speed control on the conveying unit so that the conveying volume of liquid methanol matches the heating energy of the primary vaporization unit and the secondary vaporization unit, thereby maintaining a stable vaporization state.

[0011] In a preferred embodiment, the control unit includes a temperature detection feedback module for detecting the temperature of the vaporization pipe and the secondary vaporization chamber, and adjusting the heating power of the auxiliary heating structure and the stainless steel heating plate according to the temperature feedback to achieve closed-loop vaporization control.

[0012] As can be seen from the above technical solution, compared with the prior art, the present invention has the following beneficial technical effects: Methanol undergoes a primary vaporization process to form a semi-gaseous mixture, followed by a secondary vaporization process to completely convert it into a gaseous state. This avoids the participation of semi-gaseous or liquid methanol in combustion, significantly improving combustion efficiency. Completely vaporized methanol burns more thoroughly, significantly reducing the production of harmful gases such as carbon monoxide and formaldehyde, thus reducing environmental pollution and enhancing safety. Gaseous methanol combustion is stable, producing a uniform flame that avoids fluctuations in flame size, improving heating efficiency and user experience. A quantitative delivery of liquid methanol via an electromagnetic pump, combined with a controllable heating structure, allows for stable control of the two vaporization processes, ensuring uniform fuel consumption and energy savings. The rational layout of the vaporization and combustion units allows for adaptation to existing methanol furnace installation spaces, facilitating production and retrofitting.

In the description of this application, unless otherwise stated, "a plurality of" means two or more.

[0020] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0021] Please see Figure 1-3The methanol furnace secondary gasification system of this utility model includes a conveying unit 1, a primary gasification unit 2, a gasification pipe 3, an auxiliary heating structure 4, a secondary gasification unit 5, a secondary gasification chamber 6, a stainless steel heating plate 7, a combustion unit 8, a furnace head 9, a furnace panel 10, and an igniter 11. It should be noted that, for clarity of the accompanying drawings, the methanol storage unit and control unit are not shown, but their structure and electrical connections with other units can be directly implemented by those skilled in the art based on the description. The methanol storage unit is a sealed, alcohol-resistant container, which can be made of stainless steel or high-strength plastic. It is connected to the conveying unit through pipelines to provide a stable supply of liquid methanol to the system. The control unit is a single-chip microcomputer or micro-control system that uses temperature sensor feedback to adjust the conveying unit, auxiliary heating structure, and secondary gasification heating plate in real time, achieving closed-loop control and ensuring safe and stable gasification and combustion. Liquid methanol is conveyed from the methanol storage unit to the gasification system, undergoes primary gasification and secondary complete gasification, and then achieves stable combustion at the furnace head. Specifically, the delivery unit 1 is preferably an electromagnetic pump, whose inlet is connected to the methanol storage unit, for delivering liquid methanol to the primary vaporization unit 2 at a set flow rate. The electromagnetic pump can adjust the flow rate in a pulsed or continuous manner under the command of the control unit to adapt to different combustion requirements. Its outlet is connected to the input end of the vaporization pipe 3 via a high-temperature resistant liquid delivery pipe.

[0022] Furthermore, the primary gasification unit 2 includes a gasification tube 3 and an auxiliary heating structure 4 disposed outside the gasification tube 3. The gasification tube 3 is preferably a hollow annular structure arranged along the outer ring of the burner head 9. When methanol is released from the burner head 9 and combusts, the auxiliary heating structure 4 absorbs the heat from the methanol combustion, providing a uniform heat source to the gasification tube. This allows the liquid methanol to be heated along the annular path within the gasification tube 3, increasing the heating area and heating time, and improving the primary gasification efficiency. Since the auxiliary heating structure 4 cannot actively generate heat, it may not absorb enough heat when the equipment is first started, potentially affecting the gasification effect. Therefore, in other embodiments, the auxiliary heating structure 4 can be an actively heated component, such as a resistance band, ceramic heating element, or flexible heating film, which is tightly wrapped around the outer wall of the gasification tube 3. By actively and uniformly heating the gasification tube 3, the liquid methanol can be heated into a semi-gaseous methanol mixture within the tube when the equipment is turned on.

[0023] Furthermore, to further improve gasification efficiency, a connecting pipe is provided at the bottom of the gasification pipe 3 to introduce the formed semi-gaseous methanol mixture into the secondary gasification unit 5. The connecting pipe is connected to the bottom of the secondary gasification chamber 6, allowing the mixture to enter the secondary gasification chamber from bottom to top, ensuring a single and stable flow direction, and reducing backflow and gas resistance.

[0024] Furthermore, the secondary vaporization unit 5 includes a secondary vaporization chamber 6 and a stainless steel heating plate 7 disposed at its bottom. The secondary vaporization chamber 6 can be a sealed hollow cavity made of a metal shell, with the stainless steel heating plate 7 welded to the outside of its bottom, so that the methanol mixture can be fully heated after entering the cavity. The stainless steel heating plate 7 is welded to the secondary vaporization chamber 6 to form an integral structure with it, and performs constant temperature or variable power heating under the control of the control unit, so that the semi-gaseous methanol mixture can be completely vaporized to obtain a stable and uniform combustible gas. In other embodiments, the stainless steel heating plate 7 can also be disposed on the inner side of the bottom of the secondary vaporization chamber 6, or it can be welded to the outer wall of the secondary vaporization chamber 6 to form an integral structure.

[0025] Furthermore, the fully vaporized methanol gas flows into the burner head 9 of the combustion unit 8 through the secondary vaporization unit 5. The burner head 9 has a mixing chamber and nozzles inside, and the gas is ejected from the nozzles to form a flame above the furnace panel 10. An igniter 11 is installed on one side of the burner head 9. The igniter 11 can be a high-voltage electronic ignition device or a piezoelectric ignition component, which automatically ignites the ejected methanol combustible gas under the control of the control unit, thereby forming a stable flame.

[0026] Furthermore, the control unit coordinates the operation of the entire system and is electrically connected to the delivery unit 1, the stainless steel heating plate 7, and the igniter 11. The control unit includes a temperature detection feedback module that uses temperature sensors installed on the vaporization pipe 3 and the secondary vaporization chamber 6 to detect the temperature at key locations in real time. Based on the detection results, it automatically adjusts the liquid supply rate of the delivery unit and the heating power of the two-stage heating structure to achieve a closed-loop, dynamically balanced vaporization process. In another embodiment, if the auxiliary heating structure 4 is an active heating structure, the control unit is also connected to the auxiliary heating structure 4. Through this control method, it can ensure that the vaporization pipe 3 maintains a suitable primary vaporization temperature range (e.g., 80–160°C), and the secondary vaporization chamber 6 maintains the temperature range required for complete vaporization (e.g., 160–300°C), thereby avoiding safety hazards such as liquid accumulation, backfire, and incomplete combustion, and ensuring the stability and high efficiency of methanol combustion.

[0027] Furthermore, during system operation, the control unit preheats the stainless steel heating plate 7 upon startup. Subsequently, the conveying unit 1 begins conveying liquid methanol. After passing through the secondary vaporization chamber 6, the methanol is vaporized into a semi-gas mixture, which is then output and burned through the burner head 9. The auxiliary heating structure 4 absorbs heat before initiating the first vaporization stage of secondary vaporization, working in conjunction with the secondary vaporization chamber 6 to achieve secondary vaporization. In other embodiments, if the auxiliary heating structure 4 is an active heating structure, it can actively heat the system after startup, allowing the methanol to form a semi-gas mixture through the vaporization pipe 3 before entering the secondary vaporization chamber 6 for complete vaporization. Finally, it is ejected through the burner head 9 and ignited by the igniter 11 to form a flame. During operation, the system continuously adjusts automatically based on temperature feedback to achieve stable and reliable combustion output.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
