[0025] The present invention will be further described below in detail with reference to the embodiments shown in the accompanying drawings.

[0026] Reference Figure 1-5 As shown,

[0027] A reactor with a catalyst turbulence temperature control structure comprises a reactor 1, an agitator 2 installed on the reactor 1, and a heating pipe 3 arranged in the reactor 1, wherein the heating pipe 3 is coiled to form a spoiler and is fixedly connected to the inner wall of the reactor 1, and a fixed bed 5 is detachably connected to the heating pipe 3, the surface of the fixed bed 5 is configured as a mesh surface, and the fixed bed 5 is filled with a catalyst, the particle size of the catalyst is smaller than the mesh aperture of the mesh surface, and the fixed bed 5 is located in the heating pipe 3 facing or facing away from the direction of material flow.

[0028] The heating pipe 3 in this scheme forms a spoiler by winding, which can increase the contact area and provide a better heating effect. The heating pipe 3 can provide a temperature regulation effect by feeding cold and hot water, cold and hot air, and the material can be mixed better by the turbulence. At the same time, the fixed bed 5 is installed on the heating pipe 3, and the reaction temperature of the catalyst position can be adjusted by the heating pipe 3, so that the catalyst can act more efficiently. When the fixed bed 5 is located in the direction of the heating pipe 3 facing the material flow, the material can be allowed to form a certain flushing effect on the catalyst, and the material will be decelerated after passing through the fixed bed 5, with a certain reaction time, and then flow from the edge of the heating pipe 3, and turbulence and catalysis can be formed at this time. When the fixed bed 5 is located in the direction of the heating pipe 3 facing away from the material flow, the turbulence can be carried out by the heating pipe 3 first, blocking the impact force of the material, and then reacting with the catalyst through the fixed bed 5 after relieving, on the one hand, the material can be decelerated first, and it is easier to form a reaction at the catalyst position, and the reaction temperature can be more suitable. The detachable fixed bed 5 can be convenient for cleaning and replacing the catalyst.

[0029] In a specific solution, a quick-release assembly 6 can be used between the temperature delivery pipe 3 and the fixed bed 5. The quick-release assembly 6 is provided between the temperature delivery pipe 3 and the fixed bed 5, and the fixed bed 5 is installed on the temperature delivery pipe 3 through the quick-release assembly 6. The quick-release assembly 6 includes a fixing plate 61 fixedly connected to the temperature delivery pipe 3 and a mounting plate 62 fixedly connected to the fixed bed 5. Both side edges of the fixing plate 61 are provided with a first curling edge 611, and a gap is formed between the first curling edge 611 and the fixing plate 61 after rolling up. The thickness of the mounting plate 62 at the position corresponding to the gap is less than 0.01mm. in the gap; both side edges of the mounting plate 62 are provided with a second curling edge 621 which cooperates with the corresponding first curling edge 611, and the second curling edge 621 is used to be inserted into the first curling edge 611 to form a plug-in connection, the fixing plate 61 is provided with a snap-in hole 612, and a snap buckle 622 is provided at a position corresponding to the snap-in hole 612 on the mounting plate 62. After the mounting plate 62 is plugged in through the first curling edge 611 and the second curling edge 621, it is snap-fitted with the snap-in hole 612 through the snap buckle 622 to form an assembly, and the fixed bed 5 is installed in the temperature delivery pipe 3.

[0030] When installing the fixed bed 5 on the temperature delivery pipe 3, first make the installation sheet 62 correspond to the position of the fixing sheet 61, and then insert the second curling edge 621 into the first curling edge 611. Since there is a gap between the first curling edge 611 and the fixing sheet 61 after rolling up, it will not block the insertion of the installation sheet 62. At this time, it is necessary to first let the buckle 622 break away from the obstruction between the fixing sheet 61, align the buckle 622 with the clamping hole 612, and then insert the buckle 622 to form a stable assembly between the fixing sheet 61 and the installation sheet 62, so as to prevent the fixing sheet 61 and the installation sheet 62 from being separated, causing the fixed bed 5 to fall off the temperature delivery pipe 3. When disassembling the fixed bed 5, it is only necessary to first press the buckle 622 to disengage it from the clamping hole 612, contact and lock it, and then move the installation sheet 62 to make the second curling edge 621 fall off from the first curling edge 611.

[0031] Preferably, the buckle 622 is formed by punching out the mounting plate 62 at a position corresponding to the snap-fit ​​hole 612 , and has elastic force after being bent so as to be embedded in the snap-fit ​​hole 612 through the elastic force.

[0032] Based on this structure, the mounting sheet 62 itself can be a flat steel plate, and the second curling edge 621 is formed by bending, and the two sides of the buckle 622 are separated from the mounting sheet 62 by stamping and shearing, and the buckle 622 is bent by stamping to form a curved sheet-like buckle 622 with elasticity. Figure 3 and 4 As shown in , the formed buckle 622 has elastic force and can be deformed by pressing to facilitate plugging with the fixing plate 61. After being installed in place, it can pop out and be locked by elastic force.

[0033] Further preferably, both the first curled edge 611 and the second curled edge 621 have elastic force, and the first curled edge 611 and the second curled edge 621 form an interference fit after being plugged in.

[0034] The first curled edge 611 and the second curled edge 621 are elastic, and can provide a certain error adaptation effect, which is convenient for installation, and can also provide a certain shock-absorbing effect. Since the first curled edge 611, the second curled edge 621, and the buckle 622 are all elastic, the overall installation state has a buffering effect and a shock-absorbing effect, which can make the installation state more stable and not easy to loosen.

[0035] Preferably, the size of the snap hole 612 is adapted to the snap buckle 622, and the two places where the snap buckle 622 is connected to the mounting plate 62 are arc-shaped, and the edge of the snap hole 612 is set as an arc surface 6121 for fitting the snap buckle 622. The arc surface 6121 of the snap hole 612 can fit with the snap buckle 622, which can provide support for the snap buckle 622, produce a tight fit under the elastic force of the snap buckle 622, and reduce the problem of metal debris caused by the collision between the snap buckle 622 and the snap hole 612 under the impact of the material, which affects the quality of the material.

[0036] The buckle 622 is preferably protruded away from the temperature delivery pipe 3 so that the buckle 622 can be pressed conveniently during disassembly.

[0037] In order to achieve better contact between the material and the catalyst, the temperature delivery pipe 3 has a gap after being coiled, and the gap is used for the material to pass through and enter the fixed bed 5 or to flow out of the fixed bed 5 and pass through the gap.

[0038] By utilizing the gap after the heating pipe 3 is coiled, the material can have a better circulation effect, and the contact effect between the material and the catalyst will not be reduced due to the obstruction of the heating pipe 3. The gap of the heating pipe 3 can better circulate the material, allowing the material to pass through the catalyst in the fixed bed 5 before being sent out, which can not only achieve turbulence and reduce the flow rate of the material, but also pass through the catalyst to produce a flushing effect on the catalyst, avoiding the material from forming a coating on the catalyst and affecting the activity of the catalyst. Moreover, the effect of slightly reducing the flow rate can also allow more materials to flow through the catalyst, so that the catalysts at various positions in the fixed bed 5 can be contacted and flushed, and a large amount of catalyst surface will not be out of contact with the material due to the excessive flow rate.

[0039] In a further configuration, the temperature delivery pipe 3 is connected to the fixed bed 5 to form a group, and the number of the groups is multiple, and the groups are evenly distributed along the circumferential direction on the inner wall of the reactor 1. The multiple groups of temperature delivery pipes 3 and the fixed bed 5 can provide a more stable turbulence effect and temperature adjustment effect, and at the same time make the distribution of the catalyst more uniform.

[0040] In order to improve the protection of the fixed bed 5 , the agitator 2 is coaxially arranged with the reactor 1 , and the distance between the temperature delivery pipe 3 and the agitator 2 is smaller than the distance between the fixed bed 5 and the agitator 2 .

[0041] Since the fixed bed 5 itself is detachably connected to the heating pipe 3, by allowing the heating pipe 3 to cover the fixed bed 5, the heating pipe 3 can be used to resist the impact of the material, so that the impact force on the fixed bed 5 is smaller, which helps to protect the fixed bed 5 itself and the connection between the fixed bed 5 and the heating pipe 3. In addition, after the heating pipe 3 is first buffered, the material can generate turbulence, which makes it easier to enter the fixed bed 5 from all directions, form a match with the catalyst, and make all surfaces of the catalyst contact with the material more evenly.

[0042] In order to make the catalyst more evenly distributed and better matched with the material, the spoiler formed by the temperature delivery pipe 3 extends upward from the bottom along the axial direction of the reactor body on the inner wall of the reactor 1. This arrangement allows the catalyst to be distributed evenly in the reactor 1, and the distribution is more even, without the need for high-speed stirring to evenly disperse the material in the material as in the prior art.

[0043] Preferably, the stirring blade of the stirrer 2 is a straight plate, and the extension direction of the straight plate corresponds to the stirring shaft, the side of the straight plate is fixed to the stirring shaft, and the temperature delivery pipe 3 and the fixed bed 5 are both located between the horizontal lines at both ends of the straight plate.

[0044] Reference Figure 1 and 2 As shown in , the stirring blades of the straight plate are extended up and down, and the fixed bed 5 is also extended up and down. The stirring blades can better push the material to the position of the fixed bed 5, and the fixed bed 5 has a certain thickness, and the stirring blades of the straight plate have a more obvious radial outward pushing effect, and can enter the fixed bed 5 from the side of the fixed bed 5 to cooperate with the catalyst. The length of the straight plate is longer than the temperature delivery pipe 3, and it can completely cover the fixed bed 5 and the temperature delivery pipe 3, and the effect is better.

[0045] The above is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
