Description

Technical Field

[0001] This invention relates to the field of methanol combustion technology, and in particular to a flameless combustion reactor homogenization gasification module. Background Technology

[0002] Flameless combustion is a clean combustion technology with low pollutant emissions. To study the process of achieving flameless combustion of different fuels under non-preheating conditions, a combination of experimental and numerical simulation methods was used. Flameless combustion has advantages such as uniform combustion temperature distribution, high combustion efficiency, and low pollutant emissions, making it one of the most promising combustion technologies of the 21st century.

[0003] In flameless combustion, when methanol or methanol solution is sprayed onto the catalyst, uneven concentration distribution leads to uneven heat distribution, creating a high-temperature gradient. This results in excessive heat inside the catalyst, making it prone to breakage and shortening its lifespan. Simultaneously, this uneven heat distribution also affects the precise control of the chemical reaction. Therefore, effectively addressing the heat distribution problem of methanol or methanol solution during the reaction process, removing internal heat, improving catalyst lifespan, and optimizing the preheating or gasification of raw materials are urgent technical problems to be solved in this field. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and propose a flameless combustion reactor gasification module.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a flameless combustion reactor gasification module, comprising an inlet plate and an outlet plate, wherein multiple inlets are provided on the side of the inlet plate, and multiple inlet screen pipes are fixedly connected to the surface of the inlet plate near the inlets; an outlet is provided in the middle of the outlet plate, and an outlet screen pipe is fixedly connected to the middle of the outlet plate near the outlet; two preheating pipes are fixedly installed between the inlet plate and the outlet plate; and multiple intermediate partitions are provided between the inlet plate and the outlet plate.

[0006] Furthermore, the number of the plurality of air intake screens corresponds to the plurality of air inlets, and the plurality of air intake screens are respectively connected to the plurality of air inlets. The plurality of air intake screens are located between the air intake plate and the air outlet plate. This allows the methanol and air mixture to enter from the air inlets and disperse into the plurality of air intake screens.

[0007] Furthermore, the exhaust screen pipe is connected to the exhaust port and is located between the inlet plate and the outlet plate. This allows the reacted waste gas to be discharged along the exhaust screen pipe to the outlet.

[0008] Furthermore, the multiple intermediate partitions are arranged at equal intervals. The design of the intermediate partitions ensures that the gases in different bed layers do not flow to each other, thereby ensuring that the concentration of methanol in contact with the catalyst is consistent and the heat generated is consistent.

[0009] Furthermore, both of the preheating pipes are curved coils, and the diameters of the coils after bending are different. The two preheating pipes are nested together, and the inlets and outlets of the two preheating pipes pass through the air inlet plate and the air outlet plate, respectively.

[0010] By introducing liquid into the preheating pipe and controlling the feed rate, the liquid can be preheated or vaporized to meet the chemical reaction's demand for raw material gas.

[0011] Furthermore, multiple air intake screens are equidistantly distributed on the outside of the preheating pipe.

[0012] Furthermore, the exhaust screen pipe passes through the interior of the preheating pipe.

[0013] Furthermore, multiple intermediate partitions have first through holes on their sides for the air inlet screen pipe to pass through, multiple intermediate partitions have second through holes in their center for the air outlet screen pipe to pass through, and multiple intermediate partitions have third through holes on their sides for the preheating pipe to pass through. These multiple intermediate partitions can segment the preheating pipe, thus allowing the module to increase or decrease the length of the intermediate partitions and the preheating pipe according to actual usage requirements.

[0014] The beneficial effects of this invention are:

[0015] In use, this invention utilizes a flameless combustion reactor gasification module equipped with an inlet plate, an outlet plate, an inlet screen pipe, an outlet screen pipe, a preheating pipe, and several intermediate partitions. The design of the inlet and outlet screen pipes ensures uniform dispersion of the methanol-air mixture and uniform emission of waste gas, effectively improving the uniformity of heat distribution. The intermediate partitions prevent gas flow between different bed layers, further enhancing heat distribution uniformity and extending catalyst lifespan. By controlling the feed rate, liquid preheating or gasification is achieved, optimizing the preheating or gasification effect of the raw materials and improving the accuracy of the chemical reaction. Therefore, this gasification module offers advantages such as uniform heat distribution, low gas resistance, ability to remove internal heat, ability to perform gasification or preheating, and extended catalyst lifespan.

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] like Figures 1-4 As shown, a flameless combustion reactor gasification module is disclosed, comprising an inlet plate 1 and an outlet plate 2. The inlet plate 1 has multiple inlets 101 on its side, and multiple inlet screen pipes 3 are fixedly connected to the surface of the inlet plate 1 near the inlets 101. The outlet plate 2 has an outlet 201 in its middle, and an outlet screen pipe 4 is fixedly connected to the middle of the outlet plate 2 near the outlet 201. Two preheating pipes 5 are fixedly installed between the inlet plate 1 and the outlet plate 2, and multiple intermediate partitions 6 are provided between the inlet plate 1 and the outlet plate 2.

[0025] like Figures 1-4 As shown, the number of multiple air intake screens 3 corresponds to the number of multiple air intakes 101, and the multiple air intake screens 3 are connected to the multiple air intakes 101 respectively. The multiple air intake screens 3 are located between the air intake plate 1 and the air outlet plate 2.

[0026] The mixture of methanol and air enters the inlet screen tube 3 through the inlet 101. The function of the inlet screen tube 3 is to evenly disperse the mixture and ensure that it fully contacts the flameless combustion catalyst.

[0027] like Figures 1-3 As shown, the exhaust screen pipe 4 is connected to the exhaust port 201, and the exhaust screen pipe 4 is located between the intake plate 1 and the exhaust plate 2.

[0028] The waste gas after the reaction is completed reaches the outlet 201 through the outlet screen pipe 4, and is then discharged from the outlet 201.

[0029] like Figures 1-2 As shown, multiple intermediate partitions 6 are arranged at equal intervals. Multiple air inlet screen pipes 3 are distributed at equal intervals on the outside of the preheating pipe 5. Air outlet screen pipes 4 pass through the interior of the preheating pipe 5.

[0030] The design of the intermediate partition 6 ensures that the gases in different bed layers do not flow into each other, thus ensuring a consistent concentration of methanol in contact with the catalyst and a consistent amount of heat generated. After exiting from the inlet screen pipe 3, the gas passes through the catalyst bed and reaches the outlet screen pipe 4. The thickness of the catalyst bed is basically uniform, and the gas resistance is similar, which ensures that the concentration of methanol in contact with catalysts of different heights and diameters is similar, and the amount of heat generated is similar, thus ensuring overall temperature uniformity.

[0031] like Figures 1-3 As shown, both preheating pipes 5 are curved coils, and the diameters of the coils after bending are different. The two preheating pipes 5 are nested together, and the inlet and outlet of the two preheating pipes 5 pass through the air inlet plate 1 and the air outlet plate 2, respectively.

[0032] In this embodiment, liquid can be introduced into the air inlet 101, and then preheated through the preheating pipe 5. By controlling the feed rate, the liquid can be preheated or vaporized to meet the raw material gas requirements of the chemical reaction.

[0033] like Figures 1-3 As shown, multiple intermediate partition plates 6 have first through holes on their sides for the air inlet screen pipe 3 to pass through, multiple intermediate partition plates 6 have second through holes in their middle for the air outlet screen pipe 4 to pass through, and multiple intermediate partition plates 6 have third through holes on their sides for the preheating pipe 5 to pass through.

[0034] This allows multiple intermediate partitions 6 to be fixed between the air inlet plate 1 and the air outlet plate 2, and the air inlet screen pipe 3, the air outlet screen pipe 4, and the preheating pipe 5 to pass through the intermediate partitions 6.

[0035] Working Principle: A mixture of methanol and air enters the inlet screen tube 3 through inlet 101. The inlet screen tube 3 evenly disperses the mixture, ensuring sufficient contact with the flameless combustion catalyst. The reacted exhaust gas passes through outlet screen tube 4 to outlet 201 and is then discharged. Throughout the process, the intermediate partition 6 prevents gas flow between different catalyst beds, thus ensuring consistent methanol concentration and heat generation at different catalyst bed heights. The gas exiting from inlet screen tube 3 passes through the catalyst bed and finally reaches outlet screen tube 4. The catalyst bed thickness is generally consistent, with similar gas resistance, ensuring similar methanol concentration and heat generation at different catalyst heights and diameters, thereby guaranteeing overall temperature consistency.

These preferred embodiments do not exhaustively describe all details, nor do they limit the invention to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of the invention, thereby enabling those skilled in the art to better understand and utilize the invention.
