Abstract
Description
Technical Field
[0001] This invention relates to the field of solid photoluminescence production technology, specifically to a highly efficient device for removing residual chlorine and hydrogen chloride from solid photoluminescence. Background Technology
[0002] The reactivity of phosgene is similar to that of phosgene, and it can react with a variety of compounds such as alcohols, aldehydes, amines, amides, carboxylic acids, phenols, and hydroxylamine. It can also undergo cyclization and condensation to prepare heterocyclic compounds. BTC can completely replace highly toxic phosgene in the synthesis of related products, and has significant applications in pharmaceuticals, pesticides, dyes, organic synthesis, and polymer materials. Currently, the main method for preparing phosgene involves chlorinating dimethyl carbonate with chlorine gas to generate phosgene and the byproduct hydrogen chloride. Although the reaction temperature is around 90℃, and most of the byproducts and unreacted chlorine gas enter the tail gas, a small amount of chlorine and hydrogen chloride will still remain in the phosgene product. This residual amount of chlorine and hydrogen chloride will adversely affect the subsequent storage, transportation, and application of the phosgene product.
[0003] Therefore, it is necessary to provide a highly efficient device for removing residual chlorine and hydrogen chloride from solid photopolymers to solve the problems mentioned in the background art. Summary of the Invention
[0004] To achieve the above objectives, the present invention provides the following technical solution: a highly efficient device for removing residual chlorine and hydrogen chloride from photopolymerization, comprising a reaction vessel, a channel, a bottom plate, a supporting component, and an adjusting rod, wherein an outlet pipe is connected to the upper side of the reaction vessel, and an inlet pipe is connected to the lower part of the reaction vessel. After photopolymerization is prepared using chlorine and dimethyl carbonate, nitrogen is introduced into the inlet pipe to remove residual chlorine and hydrogen chloride.
[0005] The internal sealing of the reaction vessel is slidably connected to a through groove, and a bottom plate with through holes is fixed at the bottom of the through groove. A support component is slidably connected in the through groove. The support component can support the light source. The height of the support component is adjusted by an adjusting rod, thereby adjusting the distance between the support component and the bottom plate.
[0006] Furthermore, as a preferred embodiment, the supporting component includes a supporting plate, a guide plate, and vent holes, wherein the guide plate is fixed above the supporting plate, and the vent holes are distributed on the outer circumference of the supporting plate and penetrate the supporting plate and the guide plate.
[0007] Furthermore, preferably, the outer periphery of the guide plate is higher than the inner periphery, and a feeding hole is provided in the middle of the guide plate.
[0008] Furthermore, as a preferred embodiment, when using the adjusting rod to drive the bearing assembly for height adjustment, the bearing assembly is first driven to move upward, and then after the space between the bearing assembly and the base plate is filled with solid light, the bearing assembly is driven to move downward slightly.
[0009] Furthermore, as a preferred embodiment, a limiting block for limiting the bearing component is fixed at the top of the through groove, so that the bearing component drives the through groove to move vertically upward.
[0010] Furthermore, as a preferred embodiment, a bearing seat is provided in the middle of the bearing assembly for connecting the stirring assembly, and the other end of the stirring assembly is fixedly connected to the adjusting rod.
[0011] Furthermore, as a preferred embodiment, the stirring assembly includes a rotating shaft, levers, and a dial plate, wherein the bottom of the rotating shaft is rotatably connected to a bearing seat, the top of which is driven by a motor, and multiple levers are provided on the rotating shaft, with an arc-shaped dial plate at the end of each lever.
[0012] Furthermore, as a preferred embodiment, the dial plate is hinged to the shaft and the lever, and a return torsion spring is provided between the shaft and the lever. A stop post is fixed on the bearing assembly so that the dial plate is driven to deflect when the dial plate rotates, thereby causing a portion of the solid light to tend to move towards the outer periphery of the bearing assembly.
[0013] Compared with the prior art, the present invention provides a highly efficient removal device for residual chlorine and hydrogen chloride in solid photopolymers, which has the following beneficial effects:
[0014] In this embodiment of the invention, after the reaction for preparing the solidified light is completed, an appropriate amount of nitrogen gas is introduced to drive away residual chlorine and hydrogen chloride, thereby obtaining a high-quality solidified light with extremely low residual chlorine and hydrogen chloride content. This is beneficial for the subsequent storage, transportation and use of the product, and does not change the synthesis process of the solidified light, resulting in low operating costs.
[0015] In this embodiment of the invention, after the supporting component moves upward a certain distance, the solidifying particles can flow downward from the feeding hole, thereby facilitating full contact with nitrogen. After the space between the supporting component and the base plate is filled with solidifying particles, the supporting component is driven to move downward a certain distance, thereby using the supporting component to squeeze, crush and refine the solidifying particles, facilitating the escape of residual chlorine and hydrogen chloride.
[0016] In this embodiment of the invention, when the bearing component comes into contact with the limiting block, the through slot and the bottom plate are lifted, and the solidifying particles on the bottom plate pass through the bottom plate and fall down. During the falling process, they come into full contact with nitrogen gas, thereby achieving secondary contact and ensuring that residual chlorine and hydrogen chloride can be fully discharged.

[0022] Example: Please refer to Figures 1-4 In this embodiment of the invention, a highly efficient device for removing residual chlorine and hydrogen chloride in a photopolymerization process includes a reaction tank 1, a channel 2, a base plate 3, a support assembly 5, and an adjusting rod 8. The upper side of the reaction tank 1 is connected to an outlet pipe 9, and the lower part of the reaction tank 1 is connected to an inlet pipe 10. The inlet pipe can supply different fluids according to the actual situation. For example, during the photopolymerization process, chlorine gas is introduced through the inlet pipe, and after the photopolymerization process is completed using chlorine gas and dimethyl carbonate, nitrogen gas is introduced into the inlet pipe 10 to remove residual chlorine and hydrogen chloride.
[0023] Of course, a heat preservation system and a lighting system are also required in the process of preparing solid light, but these are not within the scope of this solution and will not be discussed further.
[0024] The reaction vessel 1 is internally sealed and slidably connected with a through groove 2. A bottom plate 3 with through holes is fixed at the bottom of the through groove 2. A bearing component 5 is slidably connected in the through groove 2. The bearing component 5 can support the light source. The bearing component 5 is driven by an adjusting rod 8 to adjust its height, thereby adjusting the distance between the bearing component 5 and the bottom plate 3.
[0025] Among them, the support component 5 and the base plate 3 can form a gas buffer space. After the solidification is prepared, the solidification can be carried on the support component 5. After the nitrogen gas accumulates in the buffer space, it can pass through the support component 5 evenly, thereby taking away the residual chlorine and hydrogen chloride gas in it.
[0026] Furthermore, the supporting component 5 includes a supporting plate 51, a guide plate 52, and a vent 53. The guide plate 52 is fixed above the supporting plate 51, and the vent 53 is distributed on the outer circumference of the supporting plate 51 and penetrates the supporting plate 51 and the guide plate 52.
[0027] The outer periphery of the guide plate 52 is higher than the inner periphery, and a feeding hole 54 is provided in the middle of the guide plate 52.
[0028] Therefore, after the supporting component is lifted, the light-fixing particles can flow downward from the discharge hole 54, which facilitates full contact with nitrogen during the falling process. Furthermore, since the outer periphery of the guide plate 52 is higher than its inner periphery, the light-fixing particles can gradually flow out from the discharge hole 54. The air inlet pipe 10 can preferably be located in the lower middle part of the reaction vessel 1. At this time, the nitrogen can contact the light-fixing particles upward and be discharged upward from the vent hole 53 on the side, thus optimizing the airflow direction.
[0029] Furthermore, when using the adjusting rod 8 to drive the bearing assembly 5 to adjust its height, the bearing assembly 5 is first driven to move upward, and then after the space between the bearing assembly 5 and the base plate 3 is filled with solid light, the bearing assembly 5 is driven to move downward slightly.
[0030] The adjusting rod 8 can be driven by an external lifting system.
[0031] It should be explained that during implementation, after the supporting component 5 moves upward a certain distance, it needs to move downward a certain distance and repeat this step. On the one hand, after the supporting component 5 moves upward a certain distance, the solidifying particles can flow downward from the feed hole 54, so as to facilitate full contact with nitrogen. After the solidifying particles are filled between the supporting component 5 and the base plate 3, the supporting component 5 is driven to move downward a certain distance, so as to use the supporting component to squeeze, crush and refine the solidifying particles, so as to facilitate the escape of residual chlorine and hydrogen chloride.
[0032] In addition, a limiting block 4 for limiting the bearing component 5 is fixed at the top of the through groove 2 so that the bearing component 5 can drive the through groove 2 to move vertically upward.
[0033] During implementation, the bearing component 5 is moved upward a certain distance, then moved downward a certain distance, and this step is repeated until the bearing component 5 contacts the limiting block 4. At this time, the through groove 2 and the bottom plate 3 are lifted, and the solidifying particles on the bottom plate 3 pass through the bottom plate 3 and fall down. During the falling process, they further come into full contact with nitrogen, thereby achieving secondary contact and ensuring that residual chlorine and hydrogen chloride can be fully discharged.
[0034] Furthermore, during implementation, the supporting component 5 is moved upward a certain distance, then moved downward a small distance, and this step is repeated, during which nitrogen gas at a higher temperature is introduced.
[0035] When the supporting component 5 comes into contact with the limiting block 4, the through groove 2 and the base plate 3 are lifted, and nitrogen gas at a lower temperature is introduced during this process.
[0036] In this embodiment, a bearing seat 6 is provided in the middle of the bearing component 5 for connecting the stirring component 7, and the other end of the stirring component 7 is fixedly connected to the adjusting rod 8.
[0037] Specifically, the stirring assembly 7 includes a rotating shaft 71, levers 72, and a lever plate 73. The bottom of the rotating shaft 71 is rotatably connected to the bearing seat 6, and the top is driven by a motor. Multiple levers 72 are provided on the rotating shaft 71, and the ends of the levers 72 are provided with arc-shaped lever plates 73.
[0038] In a preferred embodiment, the dial plate 73 is hinged to the lever 72 with a shaft, and a return torsion spring is provided between the shaft and the lever 72. A stop post 74 is fixed on the bearing assembly 5 so that the stop post drives the dial plate 73 to deflect when the dial plate 73 rotates, thereby causing a portion of the solid light to tend to move towards the outer periphery of the bearing assembly 5.
[0039] It should be explained that, since the height of the outer periphery of the guide plate 52 is higher than that of its inner periphery, the light-fixing particles tend to gather towards the center. The support component 5 is fixed with a baffle 74 so that when the deflector 73 rotates, the baffle drives the deflector 73 to deflect, which in turn causes some of the light-fixing particles to tend to move towards the outer periphery of the support component 5. This promotes the full movement of the light-fixing particles, which facilitates full contact with nitrogen and the escape of residual chlorine and hydrogen chloride.
[0040] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
