Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of rectifying column, in particular to a light stabilizer post-processing rectifying column structure. BACKGROUND

[0002] Light stabilizer is an additive of high polymer products (such as plastics, rubber, paint, synthetic fiber), which can shield or absorb the energy of ultraviolet light, has the function of quenching singlet oxygen and decomposing hydrogen peroxide into non-active substances. When preparing light stabilizer, post-processing operation such as rectification is needed for the light stabilizer which has been pre-processed, so as to effectively remove impurities in the light stabilizer (mixture).

[0003] Rectifying column is a tower type gas-liquid contact device for rectification. By using the property that each component in the mixture has different volatility, i.e. the vapor pressure of each component is different at the same temperature, the light component (low-boiling substance) in the liquid phase is transferred to the gas phase, and the heavy component (high-boiling substance) in the gas phase is transferred to the liquid phase, so as to realize the purpose of separation.

[0004] However, the rectifying column structure has the following defects in specific use: 1. When the existing rectifying column structure is used for rectifying chemical products (light stabilizer, etc.), the liquid phase material in the liquid mixture state moves downward from the top of the rectifying column structure, the gas phase (vapor) for rectification floats upward from the bottom of the rectifying column structure, and the two are in contact in the interior of the rectifying column structure to realize the operation of component separation (rectification). However, for the light stabilizer in the liquid mixture state, the particle size of the liquid molecules inside is large, and the traditional way is to transport the light stabilizer in the liquid mixture state to the interior of the rectifying column structure through the pipeline transportation, so that the light stabilizer in the liquid mixture state is in the state of dripping when falling into the interior of the rectifying column structure for rectification, which results in small contact area with the gas phase material (vapor), and poor rectification effect. 2. When the existing rectifying column structure is used for rectifying the liquid phase material (light stabilizer) in the liquid mixture state and the gas phase material (vapor), due to the weight of the particles of the liquid phase material (light stabilizer), the falling speed is fast, and the contact time between the liquid phase material (light stabilizer) and the gas phase material (vapor) in the interior of the rectifying column structure is short, so that the transfer efficiency of the light component (low-boiling substance) inside the liquid phase material (light stabilizer) is low.

Compared with the prior art, the above one or more technical schemes have the following beneficial effects: 1. In the post-processing distillation tower structure for light stabilizers, when distilling the liquid material (light stabilizer) to improve its quality, the liquid material (light stabilizer) can be sprayed and transported upward and outward to expand the coverage area and area of ​​the liquid material (light stabilizer) transported to the interior of the distillation tower. This ensures that when the rising gaseous material (vapor) comes into contact with the dripping liquid material (light stabilizer), the two have a larger contact area, and the light components (low-boiling substances) in the liquid phase are transferred to the gas phase more quickly and efficiently. At the same time, the outward spraying and transport of the liquid material (light stabilizer) is achieved by extrusion, which increases the speed and distance of the transport. Furthermore, the driving force for outward injection and transport of the liquid material (light stabilizer) for pressurized injection is the impact force of the liquid material (light stabilizer) injected into the injection pipeline. Compared with traditional drive methods (such as motors), this is less expensive and less susceptible to the effects of distillation temperature. 2. In the post-processing distillation tower structure for light stabilizers, when distilling the liquid-phase material (light stabilizer), the design of the liquid-phase material (light stabilizer) flow trajectory through bending transmission can maximize the contact time between the liquid-phase material (light stabilizer) and the gas-phase material (vapor), and the duration of the liquid-phase material (light stabilizer)'s activity within the distillation tower structure, thereby improving the effectiveness and efficiency of the liquid-phase material (light stabilizer) distillation. At the same time, a portion of the liquid-phase material (light stabilizer) is always in contact with the upward-moving gas-phase material (vapor) at the top of each baffle, facilitating continuous distillation of the liquid-phase material (light stabilizer); 3. In the post-processing distillation tower structure for the light stabilizer, the impurity separation cylinder packing design within the distillation packing unit can be used to separate impurities from the gaseous material undergoing distillation and the liquid material after the distillation operation. This ensures that the impurities in the gaseous material undergoing distillation and the liquid material after the distillation operation are lower, thereby ensuring the quality of the light stabilizer after the distillation operation. At the same time, the liquid material after the distillation operation can be repeatedly introduced into the distillation packing unit through the design of a circulation pipeline, achieving multiple impurity separation operations and maximizing the quality of the liquid material (light stabilizer); 4. In the post-treatment rectification tower structure of light stabilizer, when the impurity separation operation of the liquid phase material (light stabilizer) is carried out multiple times or once (by the packing inside the distillation packing unit), the liquid phase material (light stabilizer) can be shunted by the design of the upper protrusion inside the intermediate temporary stay and the first lower recess and the second lower recess with different depths inside the upper protrusion, avoiding the liquid phase material (light stabilizer) from entering the inside of the distillation packing unit once for impurity separation operation, ensuring that the impurities inside the liquid phase material (light stabilizer) have sufficient time to be adhered by the packing inside the distillation packing unit, and improving the effect of impurity separation of the liquid phase material (light stabilizer).

[0023] In the present application, by bending the active liquid phase material (light stabilizer) inside the gas-liquid distillation assembly 30, the contact time of the liquid phase material (light stabilizer) with the gas phase material (vapor) during rectification can be maximized, and the rectification effect and efficiency can be improved.

[0024] In the present application, by designing the filler inside the filler separation assembly 40, the impurities in the gas phase material being rectified and the liquid phase material after rectification can be separated, ensuring the quality of the gas phase material and the liquid phase material.

[0025] In the present application, the circulating pipeline 50 is used for the circulating delivery of the liquid phase material after rectification, and the impurities in the liquid phase material (light stabilizer) after rectification can be separated multiple times.

[0026] With reference to Figure 6 and Figure 7 , the suspension type conveying assembly 201 comprises: a liquid phase partition plate 2011 assembled inside the upper tower body 101; a liquid phase hole 2012 opened at the eccentric position inside the liquid phase partition plate 2011; a spray pipeline 2013 assembled at the center position inside the liquid phase partition plate 2011; a liquid valve 2014 arranged at one side of the bottom of the spray pipeline 2013 and located at the bottom of the liquid phase partition plate 2011; and a liquid phase conduit 2015 connected with the liquid valve 2014 and extending to the outside of the upper tower body 101.

[0028] In the light stabilizer post-treatment rectification tower structure of the present application, when the liquid phase material (light stabilizer) enters the inside of the spray pipeline 2013 through the liquid valve 2014 and the liquid phase conduit 2015, part of the liquid phase material (light stabilizer) will enter the upper spray hole 20131 at the top through the conical baffle 20133, and the liquid phase material (light stabilizer) will be sprayed and delivered through the upper spray hole 20131. Another part of the liquid phase material (light stabilizer) will be sprayed out from the inside of the side spray hole 20132 by the pressurization of the reciprocating extrusion assembly 206, realizing the spraying and delivery of the liquid phase material (light stabilizer). At this time, by the different spraying directions and different spraying intensities of the liquid phase material (light stabilizer), the contact area between the liquid phase material (light stabilizer) and the gas phase material can be expanded.

[0029] With reference to the drawings Figure 7 and Figure 8 The liquid-phase impact assembly 202 comprises: a movable vane 2021 arranged on the side of the liquid valve 2014 and rotationally connected at the center inside the injection pipeline 2013; a center connecting rod 2022 installed on the top of the movable vane 2021; a stable support 2023 installed inside the injection pipeline 2013 and rotationally connected with the center connecting rod 2022 on the inside, wherein the outside of the center connecting rod 2022 is installed with an intermediate gear 203 rotationally connected on the top of the stable support 2023, and the top of the stable support 2023 is rotationally connected with a transmission gear 204 and a side gear 205.

[0030] In the light stabilizer post-processing rectifying tower structure of the present application, when the liquid-phase material (light stabilizer) enters the inside of the injection pipeline 2013 through the liquid valve 2014 and the liquid-phase guide pipe 2015, the impact force will drive the movable vane 2021 to work and drive the center connecting rod 2022 connected with the movable vane 2021 to rotate. When the center connecting rod 2022 rotates, the intermediate gear 203 installed on the outside will rotate.

[0031] With reference to the drawings Figure 9 and Figure 10 The reciprocating extrusion assembly 206 comprises: a side connecting rod 2061 connected on the top of the side gear 205; an injection cylinder 2062 arranged on the outside of the top of the side connecting rod 2061 and installed on the bottom of the stable support 2023; a spiral raceway 2063 arranged on the outer surface of the side connecting rod 2061 and located on the inside of the injection cylinder 2062; a reciprocating slide 2064 connected on the outside of the spiral raceway 2063 of the side connecting rod 2061 through balls; an extrusion piston 2065 connected on the top of the reciprocating slide 2064 and movably arranged inside the injection cylinder 2062; a flow distribution plate 2066 connected on the top of the side connecting rod 2061; and a positioning plate 2067 movably arranged on the top of the flow distribution plate 2066 and installed on the top of the through hole inside the stable support 2023.

[0032] In the present scheme, a plurality of side flow ports 20621 are arranged on the outside of the top of the injection cylinder 2062, the side flow ports 20621 are arranged on the side of the extrusion piston 2065, and the inside of the extrusion piston 2065 is penetrated by the side connecting rod 2061, wherein the inside of the flow distribution plate 2066 and the positioning plate 2067 is eccentrically provided with an eccentric through hole 20671, and the flow distribution plate 2066 and the positioning plate 2067 are arranged on the outside of the conical baffle 20133.

[0033] In the post-processing rectifying tower structure of the light stabilizer of the present application, when the side gear 205 rotates, the top connected side connecting rod 2061 will rotate, and through the spiral raceway 2063 opened outside, it drives the spiral raceway 2063 outside to move up and down through the ball connecting reciprocating slide 2064 (the side connecting rod 2061 and the spiral raceway 2063 constitute a screw structure). At this time, when the reciprocating slide 2064 moves up and down, it will drive the extrusion piston 2065 connected to the top to move up and down, reciprocally extruding the liquid phase material (light stabilizer) on the top of the extrusion piston 2065, so that the liquid phase material (light stabilizer) can be injected into the space inside the side flow port 20621 through the eccentric through hole 20671 inside the distribution plate 2066 and the positioning plate 2067, and injected outside the injection cylinder 2062 by pressurization, expanding the range and area size of the liquid phase material (light stabilizer) delivery.

[0034] With particular reference to Figure 11 and Figure 12 , the gas-liquid distillation assembly 30 comprises: a baffle plate 301 installed at the top inside the distillation tower body 102; a gas phase floating channel 302 arranged inside the baffle plate 301; a liquid phase ring body 303 installed outside the gas phase floating channel 302; a liquid phase through hole 304 opened at the bottom of the liquid phase ring body 303; an upper sealing cover 305 arranged at the top of the liquid phase ring body 303 and above the gas phase floating channel 302; a threaded positioning rod 306 installed and fixed to the upper sealing cover 305 and threadedly connected with the gas phase floating channel 302, wherein the baffle plate 301 is provided with a plurality of baffle plates 301, and the plurality of baffle plates 301 constitute a bent liquid phase flow passage.

[0035] In the post-processing rectifying tower structure of the light stabilizer of the present application, when the liquid phase material (light stabilizer) flows to the top of the baffle plate 301, the liquid phase material (light stabilizer) will first be ensured to always have a part of the liquid phase material (light stabilizer) located at the top of the baffle plate 301 due to the protruding part on one side of the top of the baffle plate 301. The gas phase material will contact the liquid phase material (light stabilizer) temporarily stored at the bottom of the upper sealing cover 305 due to the gas phase floating channel 302 entering the inside of the upper sealing cover 305, and the rectification operation is realized. With the continuous increase of the liquid phase material (light stabilizer), the liquid phase material (light stabilizer) will enter the top of the next baffle plate 301 through the through hole part on one side of the baffle plate 301, realizing the continuous delivery operation of the liquid phase material (light stabilizer).

[0036] With particular reference to Figure 5 , the filler separation assembly 40 comprises: a filler assembly plate 401 installed at the bottom of the distillation tower body 102; a plurality of separation holes 402 opened inside the filler assembly plate 401; a distillation filler unit 403 arranged between the two filler assembly plates 401.

[0037] In the post-processing rectifying tower structure of the light stabilizer, the impurities in the gas-phase material being rectified and the liquid-phase material after the rectification operation can be separated by the packing arranged inside the packing separation assembly 40.

[0038] Example Two In use, when the liquid-phase material (light stabilizer) is circulated through the circulation pipeline 50 for impurity separation, the liquid-phase material (light stabilizer) itself has a certain weight, and thus falls at a relatively fast speed. When a large amount of liquid-phase material (light stabilizer) enters the interior of the packing separation assembly 40, the next layer of liquid-phase material (light stabilizer) is pressed by the previous layer of liquid-phase material (light stabilizer), and thus stays in the interior of the packing separation assembly 40 for a short time, and the impurity separation effect is poor.

[0039] To this end, with reference to Figure 13 The intermediate temporary partition 60 is arranged at the middle position of the rectifying tower body 102, the top of the intermediate temporary partition 60 is provided with a plurality of upper protrusions 601, and the interiors of the upper protrusions 601 are hollow, wherein the first lower recesses 602 are arranged at the left and right sides of the middle upper protrusion 601, the second lower recesses 603 are arranged at the middle positions of the upper protrusions 601 at the side surfaces of the first lower recesses 602, and the depths of the second lower recesses 603 are greater than the depths of the first lower recesses 602.

[0040] In the post-processing rectifying tower structure of the light stabilizer, when the liquid-phase material (light stabilizer) in the circulation pipeline 50 enters the top of the intermediate temporary partition 60, the layered flow operation of the liquid-phase material (light stabilizer) can be realized by the design of the upper protrusions 601 at the top of the intermediate temporary partition 60 and the first lower recesses 602 and the second lower recesses 603 with different depths, the probability of the liquid-phase material (light stabilizer) being separated for impurities once entering the interior of the packing separation assembly 40 is reduced, the liquid-phase material (light stabilizer) can be fully contacted with the packing in the interior of the packing separation assembly 40, and the contact time is relatively long, and thus the effect of separating the liquid-phase material (light stabilizer) for impurities is effectively improved.

[0041] Therefore, any person skilled in the art should understand that, within the technical scope of the present application, equivalent replacements or changes can be made to the technical solutions and the inventive concept of the present application, and all of them should be covered within the protection scope of the present application.
