Description

Technical Field

[0001] This invention relates to the field of flameless combustion technology, and more particularly to a flameless combustion gas equalization module. Background Technology

[0002] In chemical reactors, flameless combustion is a common heating method. Flameless combustion refers to the pre-mixing of fuel gas and air before they enter the combustion chamber. Because its combustion rate depends only on the ignition and combustion reaction rates, it is faster than flaming combustion, produces a shorter flame with no distinct flame outline, hence the name flameless combustion, which belongs to dynamic combustion.

[0003] However, in current chemical reactors, the rapid reaction of methanol or methanol solution upon spraying onto the catalyst results in a high methanol concentration near the nozzle and a low concentration further away, with some areas even lacking methanol contact altogether, leading to no heat generation and a significant temperature gradient. This uneven temperature distribution affects the chemical reaction and limits the heating range of flameless combustion. Therefore, this invention proposes a flameless combustion gas equalization module. Summary of the Invention

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

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a flameless combustion gas equalization module, comprising a reactor and a gas equalization component, wherein the gas equalization component is located inside the reactor, the gas equalization component includes an upper top plate and a lower end plate, a plurality of air inlet screens are fixed on the side of the upper surface of the lower end plate and the air inlet screens are located between the upper top plate and the lower end plate, an air outlet screen is fixedly connected to the middle of the lower surface of the upper top plate and the air outlet screen is located between the upper top plate and the lower end plate, a plurality of intermediate partitions are provided between the upper top plate and the lower end plate and the plurality of intermediate partitions are arranged at equal intervals, and a fixing component for fixing the intermediate partition is provided in the middle of each intermediate partition.

[0006] Furthermore, the lower end plate has multiple air inlets on its side, and the number and position of these air inlets correspond to multiple air inlet screens. The air inlets are connected to the interior of the air inlet screens. Methanol solution can enter through the air inlets, then be distributed along the multiple air inlet screens, and finally enter the reactor.

[0007] Furthermore, an air outlet is provided in the middle of the upper top plate, the position of which corresponds to the position of the air outlet screen, and the air outlet is connected to the interior of the air outlet screen. The reacted gas can be discharged along the air outlet screen and then exit from the air outlet at one end of the air outlet screen.

[0008] Furthermore, each of the intermediate partitions has multiple first fixing holes on its side, and the number and position of the multiple first fixing holes correspond to the multiple air intake screens, with each of the multiple air intake screens passing through the multiple first fixing holes. The first fixing holes on the side of the intermediate partition are for the air intake screens to pass through, so the intermediate partition can slide on the surface of the air intake screens through the first fixing holes.

[0009] Furthermore, each of the intermediate partitions has a second fixing hole in its center, and the position of the second fixing hole corresponds to the position of the air outlet screen, through which the air outlet screen passes. The second fixing hole in the center of the intermediate partition is for the air outlet screen to pass through, so the intermediate partition can slide on the surface of the air outlet screen through the second fixing hole.

[0010] Furthermore, the fixing component includes a positioning sleeve fixed to the middle of the intermediate partition. The positioning sleeve is located outside the second fixing hole, and a screw hole is provided on the side wall of the positioning sleeve. A locking bolt is rotatably connected inside the screw hole. The positioning sleeve can slide along the surface of the air outlet screen. By sliding and changing the position of the positioning sleeve, the position of the intermediate partition can be changed. Then, by tightening the locking bolt, the positioning sleeve can be fixed, thereby fixing the intermediate partition.

[0011] Furthermore, the reactor interior and the exterior of the gas equalization assembly form a catalyst-filled chamber. Therefore, catalyst can be filled inside this chamber.

[0012] Furthermore, the reactor has a feed inlet at the bottom and a discharge outlet on one side of the top. Reactants can enter the reactor through the feed inlet and be discharged through the discharge outlet after the reaction is complete.

[0013] The beneficial effects of this invention are:

[0014] In use, this invention provides a flameless combustion gas equalization module comprising an upper top plate, a lower end plate, an inlet screen, an outlet screen, and multiple intermediate partitions. This module ensures uniform dispersion of the methanol-air mixture, guaranteeing consistent methanol concentration and heat generation in the catalyst contact area, thus ensuring overall temperature consistency. This provides more precise reaction conditions for the chemical reaction, expands the heating range of the flameless methanol combustion, and improves the efficiency and quality of the chemical reaction. Furthermore, the multiple intermediate partitions are fixed to the surface of the outlet screen using fixing components. Therefore, in practical applications, an appropriate number of intermediate partitions can be installed between the upper top plate and the lower end plate as needed, and the partitions can be fixed in place using the fixing components, making the module more flexible and convenient to use.

[0022] 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.

[0023] like Figures 1-4 As shown, a flameless combustion gas equalization module is disclosed, including a reactor 8 and a gas equalization component. The gas equalization component is located inside the reactor 8 and includes an upper top plate 1 and a lower end plate 2. Multiple air inlet screens 4 are fixed on the side of the upper surface of the lower end plate 2 and are located between the upper top plate 1 and the lower end plate 2. An air outlet screen 6 is fixedly connected to the middle of the lower surface of the upper top plate 1 and is located between the upper top plate 1 and the lower end plate 2. Multiple intermediate partitions 7 are provided between the upper top plate 1 and the lower end plate 2 and are arranged at equal intervals. Each intermediate partition 7 has a fixing component in the middle for fixing the intermediate partition 7.

[0024] like Figures 1-3As shown, the lower end plate 2 has multiple air inlets 3 on its side, and the number and position of the multiple air inlets 3 correspond to the multiple air inlet screens 4. The air inlets 3 are connected to the interior of the air inlet screens 4.

[0025] After the air inlet 3 is connected to the inside of the air inlet screen 4, the gas can enter the air inlet screen 4 along the air inlet 3. Since there are multiple air inlets 3 and multiple air inlet screens 4, the methanol can be evenly distributed.

[0026] like Figures 1-2 As shown, an air outlet 5 is provided in the middle of the top plate 1. The position of the air outlet 5 corresponds to the position of the air outlet screen 6, and the air outlet 5 is connected to the interior of the air outlet screen 6.

[0027] After the reaction is complete, the gas can enter the gas outlet screen 6 and then be discharged from the gas outlet 5 along the gas outlet screen 6.

[0028] like Figures 1-4 As shown, each intermediate partition 7 has multiple first fixing holes 71 on its side, and the number and position of the multiple first fixing holes 71 correspond to the multiple air inlet screens 4. The multiple air inlet screens 4 pass through the multiple first fixing holes 71 respectively. Each intermediate partition 7 has a second fixing hole 72 in the middle, and the position of the second fixing hole 72 corresponds to the position of the air outlet screen 6. The air outlet screen 6 passes through the second fixing hole 72.

[0029] Therefore, the intermediate partition 7 can move along the inlet screen 4 and the outlet screen 6 through the first fixing hole 71 and the second fixing hole 72. In actual use, an appropriate number of intermediate partitions 7 can be fitted onto the surfaces of the inlet screen 4 and the outlet screen 6 as needed. The intermediate partition 7 here can ensure 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.

[0030] like Figure 2 and Figure 4 As shown, the fixing component includes a positioning sleeve 73 fixed in the middle of the intermediate partition 7. The positioning sleeve 73 is located outside the second fixing hole 72. A screw hole 74 is provided on the side wall of the positioning sleeve 73. A locking bolt 75 is rotatably connected inside the screw hole 74.

[0031] The positioning sleeve 73 can move along the surface of the air outlet screen 6 with the middle partition 7. When it moves to the designated position, the middle partition 7 can be fixed by tightening the locking bolt 75. When fixing the middle partition 7, it is necessary to ensure that the distance between two adjacent middle partitions 7 is the same.

[0032] like Figure 2 As shown, the inner cavity of reactor 8 and the outside of the gas equalization component form a catalyst-filled cavity 9.

[0033] Methanol can react with the catalyst in the catalyst-filled chamber 9, and then the combustion reaction is completed.

[0034] like Figure 2 As shown, a feed inlet 10 is provided at the bottom of the reactor 8, and a discharge outlet 11 is provided on one side of the top of the reactor 8. The reaction raw materials enter the reactor 8 through the feed inlet 10, and then are discharged from the discharge outlet 11 after the reaction.

[0035] Working Principle: The methanol-air mixture enters the inlet screen 4 through the inlet 3 of the lower end plate 2. The mixture is evenly dispersed through the inlet screen 4 and comes into contact with the flameless combustion catalyst in the catalyst filling chamber 9, thus completing the combustion reaction. The exhaust gas passes through the outlet screen 6 to the outlet 5 and is finally discharged from the outlet 5. The intermediate partition 7 ensures that the gases in different bed layers do not flow into each other, guaranteeing a consistent methanol concentration and heat generation for the catalyst. Throughout the process, because the gas passes from the inlet screen 4 through the catalyst bed to the outlet screen 6, and the catalyst bed thickness is basically uniform with similar gas resistance, it ensures that catalysts of different heights and diameters have similar methanol concentrations and generate similar heat, thus ensuring overall temperature consistency. This provides more precise reaction conditions for the chemical reaction, expands the heating range of the flameless combustion of methanol, and improves the efficiency and quality of the chemical reaction.

These preferred embodiments do not exhaustively describe all details, nor do they limit the invention to any specific implementation.
