Description

Technical Field

[0001] This utility model relates to the field of fuel combustion equipment technology, and in particular to a methanol gasification combustion structure. Background Technology

[0002] In agricultural production, crops require carbon dioxide for photosynthesis, and the enclosed environment of agricultural greenhouses provides conditions for increased carbon dioxide application. Increasing carbon dioxide supply can improve yield and crop disease resistance; reports indicate that supplementing with appropriate amounts of carbon dioxide can increase crop yields by 40-100%. Currently, carbon dioxide is released in greenhouses using chemical methods, dry ice methods, and bottled carbon dioxide gas release methods. Each method has its advantages and disadvantages; the main problems are the difficulty in controlling the release amount, the lack of alignment with the crop's natural carbon dioxide absorption patterns, and the high labor input required. Carbon dioxide fertilizers can stably and continuously release carbon dioxide in a controllable manner, and are therefore widely used.

[0003] Existing carbon dioxide gas fertilizer machines generally use methanol as fuel. When the fuel burns in the combustion chamber, it cannot mix fully with air, which may result in incomplete combustion. Incomplete combustion produces byproducts such as carbon monoxide in the flue gas, which can affect crop growth. Furthermore, the heat generated in the combustion chamber cannot be utilized, leading to energy waste. Therefore, there is an urgent need for a methanol gasification combustion structure that can achieve complete combustion to solve the above problems. Utility Model Content

[0004] In order to improve the combustion efficiency of methanol fuel and to reuse the heat in the combustion chamber to save energy, this utility model provides a methanol gasification combustion structure.

[0005] This utility model provides a methanol gasification combustion structure, which adopts the following technical solution: A methanol gasification combustion structure is fixedly installed inside a carbon dioxide fertilizer generator, including a mounting base, a combustion chamber, a delivery pipe, a combustion nozzle, and a gasification component. The mounting base has an installation space inside, and the combustion chamber is located on one side of the mounting base with an opening on one side. The combustion nozzle is located in the middle of the opening of the combustion chamber. The delivery pipe has a liquid inlet and a gas outlet, and a portion of the delivery pipe is spirally arranged outside the combustion chamber. The gas outlet of the delivery pipe is fixedly connected to the combustion nozzle. The gasification component is fixedly installed on the side wall of the mounting base, and the delivery pipe passes through the gasification component. The gasification component is located between the liquid inlet and the spiral portion.

[0006] By adopting the above technical solution, the mounting base fixes multiple components inside and then inside the carbon dioxide fertilizer generator. Liquid methanol enters at the inlet end of the conveying pipe. When it passes through the gasification component, the gasification component heats up and vaporizes the methanol. The vaporized methanol is then conveyed through the conveying pipe to the combustion nozzle. Finally, the combustion nozzle sprays out the gaseous methanol and burns it in the combustion chamber. After a period of time, the temperature of the combustion chamber rises, which can transfer heat to the conveying pipe and vaporize the methanol in the conveying pipe. At this time, the gasification component can stop working, realizing the reuse of heat and saving energy.

[0007] Optionally, a storage tank is fixedly connected to the inlet end of the delivery pipe. The storage tank is connected to the delivery pipe and is used to hold methanol. The storage tank is fixedly connected in the mounting base. A connecting pipe is also provided on the side of the storage tank. A pump body is fixedly connected to the end of the connecting pipe away from the storage tank. The connecting pipe is connected to the upper part of the storage tank, and the delivery pipe is connected to the lower part of the storage tank.

[0008] By adopting the above technical solution, the pump can increase the pressure inside the storage tank, allowing methanol to flow out along the delivery pipe and ensuring a continuous supply of methanol.

[0009] Optionally, the methanol gasification combustion structure further includes a blower assembly, which includes a blower and a duct connected to the blower. The side wall of the mounting base is provided with a mounting port, the blower is fixedly installed in the mounting port, and the end of the duct away from the blower is connected to the part of the delivery pipe near the gas outlet.

[0010] By adopting the above technical solution, the blower can blow air into the duct, and the air enters the delivery pipe through the duct to mix with the gaseous methanol, ensuring that the methanol can burn completely and reducing the amount of carbon monoxide produced.

[0011] Optionally, the connection between the air duct and the delivery pipe is an inclined connection, and the flow direction in the air duct is opposite to the flow direction in the delivery pipe.

[0012] By adopting the above technical solution, after the air enters the delivery pipe in the duct, it can convect and mix fully with the gaseous methanol in the delivery pipe, which further reduces the probability of incomplete combustion of methanol under insufficient oxygen conditions and increases the amount of carbon dioxide produced.

[0013] Optionally, the vaporization assembly includes a vaporization tube, which is fixedly installed on the inner wall of the mounting base, and an electric heating wire is provided inside the vaporization tube.

[0014] By adopting the above technical solution, the delivery pipe passes through the vaporization pipe, and the heating wire can heat the delivery pipe to vaporize the methanol liquid inside, which is convenient for mixing with air and spraying out later.

[0015] Optionally, a gas detector is installed on the delivery pipe, and the gas detector is located between the combustion nozzle and the delivery pipe / air duct.

[0016] By adopting the above technical solution, the gas detector detects the gas in the delivery pipe. When the concentration is too high, the power of the pump is reduced to reduce the concentration of methanol; when the concentration is too low, the power of the pump is increased to increase the concentration of methanol, so as to ensure that the final concentration of methanol sprayed out is at a normal level.

[0017] Optionally, a flame stabilizer is provided in the combustion chamber, and the flame stabilizer is fixedly installed in the combustion chamber by at least one connecting rod.

[0018] By adopting the above technical solution, the flame stabilizer tube can limit the direction of the flame, making the flame combustion more stable.

[0019] Optionally, an igniter is provided on the side of the flame stabilizer tube near the combustion nozzle, and the head of the igniter is close to the head of the combustion nozzle.

[0020] By adopting the above technical solution, the igniter can ignite the sprayed methanol, turning it into a combustion state.

[0021] Optionally, a gas discharge pipe is provided on the side wall of the mounting base at one end of the combustion chamber.

[0022] By adopting the above technical solution, the carbon dioxide produced by methanol combustion is discharged in the gas emission pipe.

[0023] In summary, this utility model has at least one of the following beneficial technical effects: 1. The delivery pipe is spirally installed outside the combustion chamber. The vaporized methanol is delivered to the combustion nozzle through the delivery pipe. Finally, the combustion nozzle sprays out the gaseous methanol and burns it in the combustion chamber. After a period of time, the temperature of the combustion chamber rises, which can transfer heat to the delivery pipe and vaporize the methanol in the delivery pipe, so as to realize the reuse of heat and save energy.

[0024] 2. Through the configuration of the blower assembly, the blower can blow air into the duct. The air then enters the delivery pipe through the duct and mixes with the gaseous methanol, ensuring that the methanol can burn completely and reducing the amount of carbon monoxide produced. After the air enters the delivery pipe through the duct, it can convect and mix thoroughly with the gaseous methanol in the delivery pipe, further reducing the probability of incomplete combustion of methanol in the absence of oxygen and increasing the amount of carbon dioxide produced.

[0025] 3. By setting the gas detector, the gas detector detects the gas in the delivery pipe. When the concentration is too high, the pump power is reduced to reduce the concentration of methanol; when the concentration is too low, the pump power is increased to increase the concentration of methanol, so as to ensure that the final concentration of methanol sprayed out is at a normal level.

[0028] The following combination Figures 1-4 The present invention will be described in further detail below.

[0029] This embodiment discloses a methanol gasification combustion structure, referring to... Figures 1-4The system includes a mounting base 100 for protecting various components and installing them inside the carbon dioxide fertilizer generator; a storage tank for storing methanol fuel; a combustion chamber 200 for supplying methanol for combustion; a delivery pipe 300 for conveying methanol; a combustion nozzle 400 for injecting gaseous methanol; a vaporization assembly 500 for vaporizing methanol; and a blower assembly 800 for introducing air. The delivery pipe 300 is spirally arranged outside the combustion chamber 200. Methanol from the storage tank enters the delivery pipe 300, and the vaporization assembly 500 heats up to vaporize the methanol. Methanol is transported to the combustion nozzle 400 through the delivery pipe 300. During this process, the blower assembly 800 blows air into the delivery pipe 300, allowing the air to mix thoroughly with the methanol. Finally, the combustion nozzle 400 sprays out the gaseous methanol and burns it in the combustion chamber 200, reducing the amount of carbon monoxide generated. After a period of time, the temperature of the combustion chamber 200 rises, which can transfer heat to the delivery pipe 300 and vaporize the methanol in the delivery pipe 300. At this time, the vaporization assembly 500 can stop working, realizing the reuse of heat and saving energy.

[0030] Reference Figures 1-4 In this embodiment, the mounting base 100 has an installation space inside. A combustion chamber 200 is disposed on one side of the mounting base 100, surrounded by a cylindrical shell. An opening is provided on one side of the combustion chamber 200. A combustion nozzle 400 is disposed in the center of the opening of the combustion chamber 200. A delivery pipe 300 has a liquid inlet and a gas outlet. The gas outlet of the delivery pipe is fixedly connected to the combustion nozzle 400. A vaporization assembly 500 is fixedly mounted on the side wall of the mounting base 100. The delivery pipe 300 passes through the vaporization assembly 500, which is located between the liquid inlet and the spiral section. The vaporization assembly 500 includes a vaporization pipe 51. 0. The vaporization pipe 510 is fixedly installed on the inner side wall of the mounting base 100. The inner diameter of the vaporization pipe 510 is larger than the outer diameter of the delivery pipe 300. An electric heating wire 520 is installed inside the vaporization pipe 510. A flame stabilizer pipe 210 is installed inside the combustion chamber 200. The flame stabilizer pipe 210 is fixedly installed inside the combustion chamber 200 by at least one connecting rod 220. An igniter 230 is installed on the side of the flame stabilizer pipe 210 near the combustion nozzle 400. The head of the igniter 230 is close to the head of the combustion nozzle 400. A gas discharge pipe 110 is installed on the side wall of the mounting base 100 at one end of the combustion chamber 200. A temperature sensor is also installed on the outer surface of the combustion chamber 200.

[0031] Thus, the delivery pipe 300 passes through the vaporization pipe 510, and the heating wire 520 can heat the delivery pipe 300 to vaporize the methanol liquid inside, making it easier to mix with air and spray out later; the flame stabilizer 210 can limit the direction of the flame, making the flame combustion more stable; the igniter 230 can ignite the sprayed methanol, turning it into a combustion state, and the carbon dioxide produced by the methanol combustion is discharged in the gas exhaust pipe 110. When the temperature sensor reaches the preset temperature, the controller controls the heating wire 520 to turn off.

[0032] Reference Figure 2 In this embodiment, the inlet end of the delivery pipe 300 is fixedly connected to the storage tank 600, and the storage tank 600 is connected to the delivery pipe 300. The storage tank 600 is used to hold methanol and is fixedly connected to the bottom of the mounting base 100. A connecting pipe 610 is also provided on the side of the storage tank 600. A pump body 700 is fixedly connected to the end of the connecting pipe 610 away from the storage tank 600. The connecting pipe 610 is connected to the upper part of the storage tank 600, and the delivery pipe 300 is connected to the lower part of the storage tank 600.

[0033] In this way, the operation of pump 700 can increase the pressure inside storage tank 600, allowing methanol to flow out along delivery pipe 300, thus ensuring a continuous supply of methanol.

[0034] Reference Figures 1-2 In this embodiment, the blower assembly 800 includes a blower 810 and a duct 820 connected to the blower 810. The mounting base 100 has a mounting port on its side wall. The blower 810 is fixedly installed in the mounting port. The end of the duct 820 away from the blower 810 is connected to the part of the conveying pipe 300 near the air outlet. The connection between the duct 820 and the conveying pipe 300 is an inclined connection. The flow direction in the duct 820 is opposite to the flow direction in the conveying pipe 300.

[0035] In this way, the blower 810 can blow air into the duct 820, and the air enters the delivery pipe 300 through the duct 820 to mix with the gaseous methanol, ensuring that the methanol can burn completely and reducing the amount of carbon monoxide produced.

[0036] After air enters the delivery pipe 300 through the duct 820, it can convect and mix thoroughly with the gaseous methanol in the delivery pipe 300, further reducing the probability of incomplete combustion of methanol under insufficient oxygen conditions and increasing the amount of carbon dioxide produced.

[0037] Reference Figure 2 In this embodiment, a gas detector 310 is provided on the delivery pipe 300, and the gas detector 310 is located between the combustion nozzle 400 and the delivery pipe 300 and the air duct 820.

[0038] Thus, the gas detector 310 detects the gas in the delivery pipe 300. When the concentration is too high, the power of the pump body 700 is reduced to reduce the concentration of methanol; when the concentration is too low, the power of the pump body 700 is increased to increase the concentration of methanol, so as to ensure that the final concentration of methanol sprayed out is at a normal level.

[0039] It should be understood that this solution also includes a controller, the location of which is set by the operator according to the actual situation during operation. The controller is used to control the electrical components used in this solution, including but not limited to the pump body 700, fan 810, gas detector 310, heating wire 520, igniter 230, and switch buttons. The controller is an Intel processor, AMD processor, PLC controller, ARM processor, or microcontroller. It is also used in conjunction with a motherboard, memory module, storage medium, and power supply. The power supply is AC power or a lithium battery. When a display screen is provided, a display card is also provided.

[0040] The implementation principle of this embodiment is as follows: First, the controller controls the pump 700 to pump out the methanol fuel from the storage tank. The methanol fuel flows continuously out along the conveying pipe 300. The heating wire 520 in the vaporization pipe 510 operates to heat the conveying pipe 300 and vaporize the methanol. Then, the controller controls the blower 810 to blow air into the air duct 820. The air enters the conveying pipe 300 through the air duct 820 and mixes with the gaseous methanol, ensuring that the methanol can burn completely and reducing the amount of carbon monoxide produced. After the air enters the conveying pipe 300 through the air duct 820, it can convect and mix thoroughly with the gaseous methanol in the conveying pipe 300, further reducing the probability of incomplete combustion of methanol under insufficient oxygen conditions and increasing the amount of carbon dioxide produced.

[0041] Then, the gas detector 310 detects the gas in the delivery pipe 300. When the concentration is too high, the power of the pump 700 is reduced to lower the methanol concentration; when the concentration is too low, the power of the pump 700 is increased to raise the methanol concentration, ensuring that the final methanol concentration is within the normal range. Finally, the igniter 230 generates a spark to ignite the methanol. The methanol combustion produces a large amount of carbon dioxide, which is discharged in the gas exhaust pipe 110. After a period of time, the temperature of the combustion chamber 200 rises. When the temperature sensor reaches the preset temperature, the controller controls the heating wire 520 to turn off, which can transfer heat to the delivery pipe 300 and vaporize the methanol in the delivery pipe 300. The controller then controls the heating wire 520 to stop working, realizing the reuse of heat and saving energy.

[0042] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
