[0034] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0035] The core of the utility model is to provide a synthesis reactor for improving synthesis processing efficiency, which can achieve full mixing and improve synthesis processing efficiency.

[0036] In order to enable those skilled in the art to better understand the technical solution provided by the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0037] Specifically, please refer to Figure 1-Figure 3 The utility model provides a synthesis reactor for improving synthesis processing efficiency, which includes a reaction cylinder, a stirring device and a mixing tower plate 300.

[0038] The reaction cylinder has a reaction chamber, and a temperature control layer for controlling the reaction temperature is arranged on the outside of the reaction cylinder. The reaction cylinder has a material inlet 121 and a material outlet 122, and the material inlet 121 and the material outlet 122 are both connected to the reaction chamber. The material inlet 121 is used to pass the material, and the material outlet 122 is used to discharge the reaction material after the reaction. The reaction chamber of the reaction cylinder can realize the chemical reaction of the material. The temperature control layer has a cooling chamber, and a coolant inlet 131 and a coolant outlet 132 are arranged on the temperature control layer, and the coolant inlet 131 and the coolant outlet 132 are both connected to the cooling chamber. The control of the internal temperature of the reaction cylinder is achieved by adjusting the temperature of the cooling medium and the flow rate of the cooling medium.

[0039] The stirring device includes a driving mechanism 210, a stirring shaft 220, a mixing blade 230 and a propulsion spiral blade 240. The driving mechanism 210 is arranged on the outside of the reaction cylinder, and the driving mechanism 210 can be a rotating power device such as a driving motor, and the driving mechanism 210 can rotate forward or reversely. One end of the stirring shaft 220 is connected to the output end of the driving mechanism 210, and the other end of the stirring shaft 220 penetrates the reaction cylinder and is inserted into the reaction chamber of the reaction cylinder. The stirring shaft 220 is provided with a mixing blade 230 and a propulsion spiral blade 240 from top to bottom, and the mixing blade 230 and the propulsion spiral blade 240 are concentric and coaxial structures. The mixing blade 230 and the propulsion spiral blade 240 are arranged at the other end of the stirring shaft 220, which can realize the stirring and mixing of the materials in the reaction cylinder.

[0040] Specifically, the mixing blade 230 may be provided with only one layer or multiple layers. The shape of the propulsion spiral blade 240 may vary according to its application and the different characteristics of the conveyed material. Generally speaking, the shape type of the spiral blade may adopt a solid (full blade) blade, that is, the entire blade surface is continuous; a belt-type blade, which presents a belt-like structure, with a thinner middle part and thicker surroundings. The angle between the curved surface of the propulsion spiral blade 240 and the direction of movement is properly designed to improve the conveying efficiency and mixing effect of the material.

[0041] The mixing tray 300 divides the reaction chamber of the reaction cylinder into a plurality of regions. The mixing tray 300 has a stirring chamber with an upper opening, the mixing tray 300 passes through the stirring shaft 220, the stirring chamber accommodates the mixing blade 230, and the side wall of the mixing tray 300 and the inner wall of the reaction cylinder have an overflow channel. The stirring chamber of the mixing tray 300 can achieve full mixing of materials, and with the addition of new materials, the mixed reaction materials are discharged from the stirring chamber to the lower region. Specifically, the materials in the stirring chamber of the mixing tray 300 can flow into the lower region of the mixing tray 300 through the overflow channel on one side of the mixing tray 300. The lower region is stirred by advancing the spiral blade 240.

[0042] The utility model provides a synthesis reactor for improving synthesis processing efficiency. The interior of the reaction cylinder is divided into multiple areas by a mixing tray 300. The mixing tray 300 has a stirring chamber with an upper opening. A stirring device is arranged on the reaction cylinder. The stirring chamber of the mixing tray 300 contains a mixing blade 230 on a stirring shaft 220. When the material enters from the material inlet 121 of the reaction cylinder, it flows into the stirring chamber of the mixing tray 300. The material is fully mixed and starts to react under the stirring action of the mixing blade 230. The material overflows from the side of the mixing tray 300 to the next area, reacts, mixes and advances under the action of the propulsion spiral blade 240, until it finally flows out through the material outlet 122 of the reaction cylinder. A temperature control layer is arranged on the outside of the reaction cylinder. The temperature and flow rate of the cooling medium in the temperature control chamber of the temperature control layer are controlled to achieve the control of the internal temperature of the reaction cylinder.

[0043] By using the mixing blade 230 to fully mix in the stirring chamber of the mixing tower plate 300, and the propulsion spiral blade 240 to further mix and stir, the stirring is made more uniform, which effectively improves the synthesis processing efficiency. At the same time, the higher aspect ratio makes the heat exchange area corresponding to the unit reaction volume larger, and it is easier to use the temperature control layer to control the temperature of the reaction cylinder; compared with the existing synthesis reactor for improving the synthesis processing efficiency, the material backmixing is less, and the residence time of the product in the reactor is more uniform, so that the product quality is more stable.

[0044] In a specific embodiment, Figure 2 As shown, the reaction cylinder includes an upper end cap 110, an inner cylinder 120 and an outer shell 130. The outer shell 130 is sleeved on the outer side of the inner cylinder 120 and forms a temperature control layer with a temperature control cavity. The upper end cap 110 and the inner cylinder 120 are buckled to form a closed cavity, which is the reaction cavity. The inner cylinder 120 and the outer shell 130 are an integrally formed structure, or the two ends are sealed and connected by welding or the like. The upper end cap 110 and the inner cylinder 120 are connected by a flange 111.

[0045] The overall diameter of the reaction cylinder is 50mm-1000mm, preferably 50mm-600mm, and the overall aspect ratio of the reaction cylinder is 4-30, preferably 10-20. The above parameter values ​​can effectively increase the area per unit volume and facilitate temperature control.

[0046] The driving mechanism 210 can be installed on the upper part of the upper head 110. The mixing tray 300 is arranged on the upper part of the inner cylinder 120, and the mixing blade 230 is arranged on the upper side of the mixing tray 300. During installation, the mixing tray 300 can be fixed on the inner wall of the reaction cylinder by means of a bracket or welding. The internal parts of the reactor such as the mixing blade 230 and the propulsion spiral blade 240 can be entered or taken out from the opening above the inner cylinder 120 of the reaction cylinder.

[0047] In order to reasonably utilize the space, a material inlet 121 is provided on the upper side of the inner cylinder 120, and the material inlet 121 penetrates the outer shell 130 and communicates with the reaction chamber of the inner cylinder 120. A material outlet 122 is provided at the bottom of the inner cylinder 120, and the material outlet 122 penetrates the outer shell 130 and communicates with the reaction chamber of the inner cylinder 120. Of course, the number and position of the material inlet 121 and the material outlet 122 can also be adaptively improved according to actual needs, and according to the characteristics of the reaction process, the material can be added in different ways from different positions of the synthesis reactor for improving the synthesis processing efficiency, such as co-current, countercurrent or segmented addition.

[0048] The temperature control cavity formed between the outer shell 130 and the inner cylinder 120 is used to pass the cooling medium.

[0049] In one form, in order to improve the heat exchange efficiency, the coolant inlet 131 is arranged on the bottom side of the shell 130, and the coolant outlet 132 is arranged on the top side of the shell 130. The flow direction of the cooling medium is opposite to the flow direction of the reaction material, thereby improving the heat exchange temperature difference.

[0050] In another form, the coolant inlet 131 is disposed on the top side of the housing 130, and the coolant outlet 132 is disposed on the bottom side of the housing 130. The coolant inlet 131 can be disposed adaptively according to actual needs.

[0051] In a specific embodiment, a gas outlet 112 is provided on the reaction cylinder, and the gas outlet 112 can be provided at the upper part of the reaction cylinder, especially at the upper part of the upper head 110. The gas outlet 112 is mainly used to replace the entire reactor system with nitrogen or other inert gases before the reaction starts, and to discharge gases such as oxygen in the reaction chamber of the reaction cylinder.

[0052] This solution also includes a pressure gauge and / or a thermometer connected to the gas outlet 112 of the reaction cylinder, so as to detect the pressure and temperature inside the reaction cylinder.

[0053] In order to guide the material entering the reaction cylinder, an impact baffle 400 is provided on the inner wall of the reaction cylinder and above the material inlet 121. The impact baffle 400 and the inner wall of the reaction cylinder form a downwardly opening guide channel. After the material is ejected into the reaction cylinder from the material inlet 121, the flow direction of the material at the material inlet 121 is perpendicular to the axis of the reaction cylinder. The material is blocked by the impact baffle 400, and the flow direction of the material is changed to a vertical downward direction.

[0054] like Figure 1 As shown, after the material enters the reaction cylinder from the material inlet 121, it first enters the stirring chamber of the mixing tray 300 located at the top layer, and then overflows to the propulsion spiral blade 240 below after the mixing reaction.

[0055] In a specific embodiment, Figure 3 As shown, the other end of the stirring shaft 220 is rotatably connected to the reaction cylinder through a thrust bearing 250. The thrust bearing 250 can withstand the force in the direction parallel to the stirring shaft 220, which can ensure the stable operation of the stirring device when subjected to axial load and extend the life of the synthesis reactor.

[0056] In a specific embodiment, the number of the mixing trays 300 may be one or more. In a specific embodiment, a plurality of mixing trays 300 are arranged along the height direction of the stirring shaft 220. Each mixing tray 300 is arranged in the reaction cylinder at equal or unequal intervals. The bottom of the mixing tray 300 may be a flat plate. The stirring shaft 220 passes through the bottom of the mixing tray 300 and is arranged perpendicular to the bottom of the mixing tray 300. The diameter of the bottom of the mixing tray 300 is smaller than the inner diameter of the reaction cylinder at the cross section.

[0057] In a further specific embodiment, the overflow channels of adjacent mixing trays 300 are arranged in a staggered manner, so that the material overflowing from the mixing tray 300 of the upper layer can completely enter the stirring chamber of the mixing tray 300 of the lower layer.

[0058] The interior of the reaction cylinder is divided into a plurality of different mixing reaction areas (i.e., stirring chambers) by using a plurality of mixing trays 300, and each mixing reaction area is provided with a mixing blade 230 for sufficient mixing. Such a configuration has a simple structure, uniform reaction, and forms a plug flow reactor with a substantially uniform residence time.

[0059] In a specific embodiment, the mixing tower plate 300 includes a semicircular bottom plate and a side wall. The semicircular bottom plate has an arc-shaped edge and a straight edge. The arc-shaped edge of the semicircular bottom plate is completely matched with the inner wall of the reaction cylinder. The side wall is vertically arranged on the straight edge of the semicircular bottom plate to form a stirring chamber between the mixing tower plate 300 and the inner wall of the reaction cylinder.

[0060] The semicircular shape of the semicircular bottom plate is greater than one-half of a circle, and preferably, can be a three-quarter circular plate. Of course, the mixing tray 300 can also be in other forms, as long as the mixing tray 300 has a stirring chamber with an upper opening.

[0061] like Figure 1As shown, there are no openings on the bottom and sides of the mixing tray 300. For example, when the materials are a methanol solution of dimethyl oxalate and a methanol solution of liquid ammonia, the two materials enter the reaction cylinder through the material inlet 121 in turn, flow into the stirring chamber of the mixing tray 300 under the action of the anti-collision baffle 400, mix and react under the stirring action of the mixing blade 230, and the mixed reaction materials overflow from the overflow channel on the side edge of the mixing tray 300 and enter the reaction chamber, and are mixed and stirred by the propulsion spiral blade 240, and continue to flow downward and react under the action of the propulsion spiral blade 240. Finally, the mixed slurry after the reaction is completed flows out of the reaction cylinder through the material outlet 122 set at the bottom.

[0062] The synthesis reactor provided by this solution uses a mixing tray 300 to fully mix the reaction materials. The mixed materials flow downward evenly under the action of the propulsion spiral blade 240, reducing the problems of uneven stirring and uneven residence time in the traditional reaction cylinder. Compared with the existing reaction cylinder, there is less back mixing, more uniform stirring, more uniform reaction time, and more stable product quality.
