Description

Technical Field

[0001] The utility model relates to the technical field of chemical equipment, in particular to a multi-position vacuum light removal device applied in the chemical field. Background Art

[0002] In the laboratory synthesis process of chemical, pharmaceutical and chemical products, dehydration of raw materials and products is a necessary treatment method. Dehydration includes dehydration and removal of volatile solvents.

[0003] The production of some important monomers for polymer chemical applications, particularly ultrafine and ultra-low-density specialty resins, places even stricter demands on monomer quality. Traditional methods of monomer dehydration, relying solely on vapor and liquid phase dehydration, are no longer sufficient to meet these requirements. Instead, a solid-caustic soda dryer or solid-caustic soda dehydration unit is required to dry and absorb the water from the raw materials used to produce the monomers. For example, in most PVC plants, as vinyl chloride gas passes through the solid-caustic soda bed of the rod caustic soda dryer, the water in the vinyl chloride comes into contact with the rod caustic soda. This strong absorption of the rod caustic soda absorbs the water, increasing the amount of water absorbed around the rod caustic soda, forming lye on its surface. This lye then flows downward by gravity to the bottom of the tank, causing large amounts of lye to accumulate at the bottom, easily clogging the pipelines. This clogging necessitates tank emptying, which wastes both rod caustic soda and labor. Furthermore, the hot water jacket at the bottom of the solid-caustic soda dryer directly heats the tank, exacerbating caustic corrosion and shortening the equipment's lifespan.

[0004] In addition, the solid alkali used by manufacturers is mostly large pieces of caustic soda. After absorbing water, the solid alkali is prone to crystallization in winter, causing blockage. The water removal effect is poor, and it is difficult to clean when blocked. It is very dangerous and prone to safety accidents.

[0005] Therefore, a multi-position vacuum delightening device is needed to overcome one or more of the above-mentioned drawbacks. Utility Model Content

[0026] In order to explain the technical content and structural features of the present invention in detail, the following is a further description in conjunction with the embodiments and the accompanying drawings.

[0027] See also Figure 1 The multi-position vacuum desalination device 100 of the present invention includes a multi-position distribution pipe 10, a condenser 20 and a desalination unit 100a. The desalination unit 100a includes a first stuffing processor 30, a second stuffing processor 40 and a third stuffing processor 50 arranged in series to meet the need of the sample passing through the first stuffing processor 30, the second stuffing processor 40 and the third stuffing processor 50 in sequence; the inlet end 31 of the first stuffing processor 30 is connected to an inlet check valve 32 to prevent the sample from being sucked back from the desalination unit 100a to the condenser 20; the outlet end 51 of the third stuffing processor 50 is connected to an outlet check valve 52 to prevent it from being sucked back to the desalination unit 100a. The outlet end 11 of the multi-position distribution pipe 10 is connected to the inlet end 21 of the condenser 20, and the outlet end 22 of the condenser 20 is connected to the inlet check valve 32 to meet the need of the sample in the multi-position distribution pipe 10 to flow to the desalination unit 100a after being processed by the condenser 20. Specifically, Figure 1 As an example, the multi-position vacuum delightening device 100 of the present invention further includes a delightening connector 60, which includes a plurality of buffer containers 61 arranged side by side. The inlet end 611 of each buffer container 61 is provided with a joint 62 and a precision adjustment valve 63 in sequence. The inlet end 12 of the multi-position distribution pipe 10 is connected to each buffer container 61 respectively. Therefore, with the help of the buffer container 61, in addition to playing a buffering role, the light components therein can also be collected and discharged. With the help of the joint 62, the assembly operation between the delightening connector 60 and the external supporting equipment is facilitated. With the help of the precision adjustment valve 63, the amount of sample entering the multi-position distribution pipe 10 can be accurately controlled. More specifically, as follows:

[0028] like Figure 1 As shown, as an example, a stop valve 13 is connected between the outlet end 11 of the multi-position distribution pipe 10 and the inlet end 21 of the condenser 20, but the present invention is not limited thereto.

[0029] Combine Figure 1 and Figure 2 As an example, the buffer container 61 is a tank body, such as but not limited to a stainless steel tank body; in addition, the joint 62 is a tower-shaped joint, which improves the assembly operation between the joint 62 and external supporting equipment; in addition, the precision adjustment valve 63 is a needle valve; obviously, according to actual needs, the joint 62 can also be a shape well known in the art, and the precision adjustment valve 63 can also be a valve well known in the art.

[0030] like Figure 1As shown, the outlet end 33 of the first stuffing processor 30 is connected to a first outlet stop valve 34; the inlet end 41 of the second stuffing processor 40 is connected to a first inlet stop valve 42, and the outlet end 43 of the second stuffing processor 40 is connected to a second outlet stop valve 44; the inlet end 53 of the third stuffing processor 50 is connected to a second inlet stop valve 59; the first outlet stop valve 34 is connected to the first inlet stop valve 42 via a first connecting pipe 71, and the second outlet stop valve 44 is connected to the second inlet stop valve 54 via a second connecting pipe 72. Therefore, the cooperation between the first outlet stop valve 34 and the inlet check valve 32 ensures the reliability of the operation of the first stuffing processor 30; the cooperation between the first inlet stop valve 42 and the second outlet stop valve 44 ensures the reliability of the operation of the second stuffing processor 40; and the cooperation between the second inlet stop valve 54 and the outlet check valve 52 ensures the reliability of the operation of the third stuffing processor 50. The first connecting pipe 71 and the second connecting pipe 72 ensure that the sample flows sequentially from the first stuffing processor 30 to the third stuffing processor 50. For example, the first filler processor 30 is a solid alkali filler processor that primarily absorbs moisture; the second filler processor 40 is an activated carbon filler processor that primarily absorbs oily components; and the third filler processor 50 is a molecular sieve filler processor that can absorb both moisture and oily components. Therefore, the light fraction removal unit 100a can absorb and process multiple light fractions. The detailed structures of the first through third filler processors 30, 50, are described below.

[0031] like Figure 3 and Figure 4 As shown, as an example, the first filler processor 30 includes a closed cavity 35, an air inlet pipe (see reference numeral 31), an air outlet pipe (see reference numeral 33), and a porous filler layer 36 filled in the inner space of the closed cavity 35. The porous filler layer 36 and the first end wall 351 (such as but not limited to) of the closed cavity 35 are connected. Figure 3 There is a first gap 352 between the porous filler layer 36 and the second end wall 353 (for example but not limited to) opposite to the closed cavity 35 Figure 3 There is a second gap 354 between the lower end wall of the closed cavity 35. The air inlet pipe penetrates the closed cavity 35 in a sealed manner outside the closed cavity 35 and extends into the first gap 352. Figure 3 As shown; the air inlet pipe forms the inlet end 31 of the first filler processor 30, that is, the reference numeral 31 also represents the air inlet pipe. The air outlet pipe is sealed outside the closed cavity 35 and penetrates the closed cavity 35 and passes through the porous filler layer 36, and then extends to the second gap 354. Figure 3As shown; the air outlet pipe forms the outlet end 33 of the first filler processor 30, that is, the figure numeral 33 also represents the air outlet pipe. Therefore, by virtue of the design that "the porous filler layer 36 is filled in the internal space of the closed cavity 35 and has a first gap 352 and a second gap 354 corresponding to the first end wall 351 and the second end wall 353 of the closed cavity 35 respectively" and "the air inlet pipe is sealed and fits into the closed cavity 35 outside the closed cavity 35 and extends into the first gap 352, and the air outlet pipe is sealed and fits into the closed cavity 35 outside the closed cavity 35 and passes through the porous filler layer 36 and extends into the second gap 354", the first filler processor 30 can improve the filling efficiency, increase the filler adsorption area, and increase the porosity of the porous filler layer 36, thereby greatly improving the adsorption treatment effect. For example, the porous filler layer 36 of the first filler processor 30 is a solid alkali filler layer to further improve the water removal ability.

[0032] Recombination Figure 3 and Figure 4 As an example, the closed cavity 35 includes a cylinder 355 and one end of the cylinder 355 (for example but not limited to Figure 3 The upper end of the cover body) is assembled and connected, and the other end opposite to the cylinder 355 (for example but not limited to Figure 3 The air inlet pipe 31 and the air outlet pipe 33 are each inserted into the cover. The cylinder 355 and the cover are detachably connected by a clamp 37. The cylinder 355 and the blind plate are also detachably connected by a clamp 37. That is, there are at least two clamps 37: one for assembling the cylinder 355 and the cover, and the other for assembling the cylinder 355 and the blind plate. The cover forms a first end wall 351 of the enclosed cavity 35, and the blind plate forms a second end wall 352 of the enclosed cavity 35. In other words, reference numeral 351 also designates the cover, and reference numeral 352 also designates the blind plate. In addition, the air inlet pipe 31 is connected to an annular porous pipe 38 located in the first gap 352, so that the sample entering from the air inlet pipe 31 passes through the annular porous pipe 38 and is more evenly dispersed in the first gap 352. The barrel 355 and the cover are detachably connected by the clamp 37, and the barrel 355 and the blind plate are also detachably connected by the clamp 37, which improves the convenience of disassembly and installation of the first filler processor 30, thereby facilitating inspection, maintenance, filling and blockage resolution operations. Figure 4As an example, the clamp 37 includes a screwing operation member 37a and two arc-shaped buckles 37b with their head ends 371 hinged to each other and their tail ends 372 connected side by side. The screwing operation member 37a is inserted into the tail end 372 of the buckle 37b; therefore, the buckle 37b is tightened or loosened by the screwing operation of the screwing operation member 37a, which more effectively facilitates the operator to disassemble and install the first stuffing processor 30.

[0033] like Figure 5 and Figure 6 As shown, as an example, the second filler processor 40 includes a closed cavity 45, an air inlet pipe (see reference numeral 41), an air outlet pipe (see reference numeral 43), and a porous filler layer 46 filled in the inner space of the closed cavity 45. The porous filler layer 46 and the first end wall 451 (such as but not limited to) of the closed cavity 45 are connected. Figure 5 There is a first gap 452 between the porous filler layer 46 and the second end wall 453 (for example but not limited to) opposite to the closed cavity 45. Figure 5 There is a second gap 454 between the lower end wall of the closed cavity 45. The air inlet pipe penetrates the closed cavity 45 in a sealed manner outside the closed cavity 45 and extends into the first gap 452. Figure 5 As shown; the air inlet pipe forms the inlet end 41 of the second filler processor 40, that is, the reference numeral 41 also represents the air inlet pipe. The air outlet pipe is sealed outside the closed cavity 45 and penetrates the closed cavity 45 and passes through the porous filler layer 46, and then extends to the second gap 454. Figure 5 As shown; the air outlet pipe forms the outlet end 43 of the second filler processor 40, that is, the figure numeral 43 also represents the air outlet pipe. Therefore, by virtue of the design that "the porous filler layer 46 is filled in the internal space of the closed cavity 45 and has a first gap 452 and a second gap 454 corresponding to the first end wall 451 and the second end wall 453 of the closed cavity 45 respectively" and "the air inlet pipe is sealed and fits into the closed cavity 45 outside the closed cavity 45 and extends into the first gap 452, and the air outlet pipe is sealed and fits into the closed cavity 45 outside the closed cavity 45 and passes through the porous filler layer 46 and extends into the second gap 454", the second filler processor 40 can improve the filling efficiency, increase the filler adsorption area, and increase the porosity of the porous filler layer 46, thereby greatly improving the adsorption treatment effect. For example, the porous filler layer 46 of the second filler processor 40 is an activated carbon filler layer to further improve the ability to absorb oily components.

[0034] Recombination Figure 5 and Figure 6 As an example, the closed cavity 45 includes a cylinder 455 and one end of the cylinder 455 (for example but not limited to Figure 5The upper end of the cover body is assembled and connected, and the other end opposite to the cylinder 455 (for example, but not limited to Figure 5 The air inlet pipe 41 and the air outlet pipe 43 are each inserted into the cover. The cylinder 455 and the cover are detachably connected by a clamp 47. The cylinder 455 and the blind plate are also detachably connected by a clamp 47. That is, there are at least two clamps 47: one for assembling the cylinder 455 and the cover, and the other for assembling the cylinder 455 and the blind plate. The cover forms a first end wall 451 of the enclosed cavity 45, and the blind plate forms a second end wall 452 of the enclosed cavity 45. In other words, reference numeral 451 also designates the cover, and reference numeral 452 also designates the blind plate. In addition, the air inlet pipe 41 is connected to an annular porous pipe 48 located in the first gap 452, so that the sample entering from the air inlet pipe 41 passes through the annular porous pipe 48 and is more evenly dispersed in the first gap 452. The barrel 455 and the cover are detachably connected by the clamp 47, and the barrel 455 and the blind plate are also detachably connected by the clamp 47, which improves the convenience of disassembly and installation of the second stuffing processor 40, thereby facilitating inspection, maintenance, stuffing and blockage resolution operations. Figure 6 As an example, the clamp 47 includes a screwing operation member 47a and two arc-shaped buckles 47b with their head ends 471 hinged to each other and their tail ends 472 connected side by side. The screwing operation member 47a is inserted into the tail end 472 of the buckle 47b; therefore, the buckle 47b is tightened or loosened by the screwing operation of the screwing operation member 47a, which more effectively facilitates the operator to disassemble and install the second stuffing processor 40.

[0035] like Figure 7 and Figure 8 As shown, as an example, the third filler processor 50 includes a closed cavity 55, an air inlet pipe (see reference numeral 53), an air outlet pipe (see reference numeral 51), and a porous filler layer 56 filled in the inner space of the closed cavity 55. The porous filler layer 56 and the first end wall 551 (such as but not limited to) of the closed cavity 55 are connected. Figure 7 There is a first gap 552 between the porous filler layer 56 and the second end wall 553 (for example but not limited to) opposite to the closed cavity 55. Figure 7 There is a second gap 554 between the lower end wall of the closed cavity 55. The air inlet pipe is sealed and fits into the closed cavity 55 outside the closed cavity 55 and extends into the first gap 552. Figure 7As shown; the air inlet pipe forms the inlet end 53 of the third filler processor 50, that is, the reference numeral 53 also represents the air inlet pipe. The air outlet pipe is sealed outside the closed cavity 55 and penetrates the closed cavity 55 and passes through the porous filler layer 56, and then extends to the second gap 554. Figure 7 As shown; the air outlet pipe forms the outlet end 51 of the third filler processor 50, that is, the figure numeral 51 also represents the air outlet pipe. Therefore, by virtue of the design that "the porous filler layer 56 is filled in the internal space of the closed cavity 55 and has a first gap 552 and a second gap 554 corresponding to the first end wall 551 and the second end wall 553 of the closed cavity 55 respectively", and "the air inlet pipe is sealed and fits into the closed cavity 55 outside the closed cavity 55 and extends into the first gap 552, and the air outlet pipe is sealed and fits into the closed cavity 55 outside the closed cavity 55 and passes through the porous filler layer 56 and extends into the second gap 554", the third filler processor 50 can improve the filling efficiency, increase the filler adsorption area, and increase the porosity of the porous filler layer 56, thereby greatly improving the adsorption treatment effect. For example, the porous filler layer 56 of the third filler processor 50 is a molecular sieve filler layer to further improve the ability to absorb moisture and oily components.

[0036] Recombination Figure 7 and Figure 8 As an example, the closed cavity 55 includes a cylinder 555 and one end of the cylinder 555 (for example but not limited to Figure 7 The upper end of the cover body is assembled and connected, and the other end opposite to the cylinder 555 (for example, but not limited to Figure 7The air inlet pipe 53 and the air outlet pipe 51 are each inserted into the cover. The cylinder 555 and the cover are detachably connected by a clamp 57. The cylinder 555 and the blind plate are also detachably connected by a clamp 57. That is, there are at least two clamps 57, one for assembling and connecting the cylinder 555 and the cover, and the other for assembling and connecting the cylinder 555 and the blind plate. Furthermore, the cover forms a first end wall 551 of the enclosed cavity 55, and the blind plate forms a second end wall 552 of the enclosed cavity 55. That is, reference numeral 551 also represents the cover, and reference numeral 552 also represents the blind plate. In addition, the air inlet pipe 53 is connected to an annular porous pipe 58 located in the first gap 552, so that the material entering from the air inlet pipe 53 passes through the annular porous pipe 58 and is more evenly dispersed in the first gap 552. Among them, the barrel 555 and the cover are detachably connected by the clamp 57, and the barrel 555 and the blind plate are also detachably connected by the clamp 57, which improves the convenience of disassembly and installation of the third stuffing processor 50, thereby facilitating inspection, maintenance, stuffing and blockage resolution operations. In addition, Figure 8 As an example, the clamp 57 includes a screwing member 57a and two arcuate retaining rings 57b with their first ends 571 hinged to each other and their tail ends 572 joined side by side. The screwing member 57a is inserted into the tail ends 572 of the retaining rings 57b. That is, the first ends 571 of the two retaining rings 57b are hinged to each other and their tail ends 572 are joined side by side. Therefore, the screwing of the screwing member 57a causes the retaining rings 57b to tighten or loosen, effectively facilitating the operator's removal and installation of the third stuffing handler 50. The outlet pipe 51 is also provided with a shut-off valve 59 disposed behind the outlet check valve 53.

[0037] Compared with the prior art, with the aid of a multi-position distribution pipe 10, a plurality of samples can be subjected to light removal treatment at the same time; with the aid of a light removal unit 100a comprising a first filler processor 30, a second filler processor 40 and a third filler processor 50 arranged in series, since the fillers of the first filler processor 30, the second filler processor 40 and the third filler processor 50 are different, a plurality of light components can be absorbed and processed; thus, the multi-position vacuum light removal device 100 of the present invention has a strong processing capacity and a good light removal effect.

[0038] It is worth noting that, because the multi-position vacuum light removal device 100 of the present invention is used in the chemical industry, the multi-position distribution pipe 10, condenser 20, light removal unit 100a, and light removal connector 60 are all made of stainless steel. Furthermore, the aforementioned "multi-position" refers to multiple workstations, and the aforementioned "light removal" refers to the removal of light components.
