Technical Field

[0001] The utility model relates to a catalytic distillation tower and belongs to the technical field of distillation towers. Background Art

[0002] The catalytic distillation tower is a special equipment that couples catalytic reaction with distillation separation. During long-term operation, the catalyst will gradually deactivate and need to be replaced and reloaded regularly.

[0003] The traditional catalyst replacement and loading process mainly adopts manual operation: the operator needs to manually spread the catalyst particles into the tower layer by layer through the manhole on the top of the tower, and use vibration equipment or manual knocking on the tower wall to make the particles stack tightly, thereby reducing the bed void ratio.

[0004] However, the traditional catalyst replacement and loading process has the following limitations: first, the manual spreading method makes it difficult to ensure the uniform distribution of catalyst particles, which can easily lead to local differences in stacking density in the bed; second, the limited space in the tower poses a safety hazard to the operation, and the loading efficiency is low, making the replacement process time-consuming and labor-intensive.

[0012] Furthermore, the catalytic bin comprises: a main body connected with a lower tower body and an upper tower body, a flow hole is penetrated through the main body, and the lower tower body and the upper tower body can be connected through the flow hole.

[0013] A slot is also provided on the side of the main body, and the slot is cross-connected with the flow hole; the plug-in board can be plugged into the slot.

[0014] Slide grooves are also arranged on both sides of the slot; the guide protrusions can be arranged in the slide grooves in a coordinated manner.

[0015] Furthermore, a handle is provided on one side of the board body.

[0016] Furthermore, the catalyst mesh box includes: a box body, and a cover plate is provided on the box body.

[0017] Furthermore, the number of catalytic components provided is at least 2 groups.

[0018] Compared with the prior art, the utility model has the following beneficial effects:

[0019] The catalyst can be pre-loaded evenly into the catalyst assembly from the outside to ensure the quality of the catalyst loading. When replacing the catalyst, workers only need to insert the catalyst assembly into the catalyst bin from the outside of the tower.

[0032] The lower tower body 1 and the upper tower body 4 are connected via the catalytic chamber 3, and the combination of the three can form a reaction chamber inside; the fluid material in the reaction chamber can pass through the catalytic component 2 to achieve a catalytic reaction.

[0033] The catalytic assembly 2 includes: an insert plate 201 that can be inserted into the catalytic bin 3, on which a catalyst mesh box 204 and a filler mesh 203 for dispersing fluid materials are fixed, and the filler mesh 203 and the catalyst mesh box 204 are stacked; a sealing air bag 202 is embedded on the insert plate 201 for sealing between itself and the catalytic bin 3.

[0034] The sealing airbag 202 is provided with an air source interface, such as Figure 6 As shown; before the plug plate 201 is inserted into the catalytic chamber 3, the interior is emptied and is in an empty state. After the plug plate 201 is installed to the specified position in the catalytic chamber 3, the sealing airbag 202 is connected to the external air source, and the sealing airbag 202 expands between the plug plate 201 and the inner wall of the catalytic chamber 3 to achieve sealing.

[0035] Specifically, the plug board 201 includes a board body 2011 , a guide protrusion 2012 is provided on the side of the board body 2011 , and a guide wheel 2015 is provided on the guide protrusion 2012 .

[0036] The plate body 2011 is provided with a seat hole 2013 , in which the filler net 203 and the catalyst net box 204 can be clamped.

[0037] In this embodiment, the catalyst can be evenly and tightly loaded into the catalyst mesh box 204, and the filler mesh 203 is placed below the catalyst mesh box 204. During the distillation process, the gas and liquid can be more evenly guided and rectified by the filler mesh 203 and enter the catalyst mesh box 204, ensuring that the catalytic reaction proceeds evenly.

[0038] The plate body 2011 is provided with a sealing groove 2014 , which is arranged at the outer circle of the seat hole 2013 ; the sealing airbag 202 is clamped in the sealing groove 2014 .

[0039] Specifically, the catalytic chamber 3 includes: a main body 301 connected to the lower tower body 1 and the upper tower body 4 , and a flow hole 302 is penetrated through the main body 301 , and the lower tower body 1 and the upper tower body 4 can be connected through the flow hole 302 .

[0040] A slot 303 is also provided on the side of the main body 301, and the slot 303 is cross-connected with the flow hole 302; the plug board 201 can be inserted into the slot 303;

[0041] After the insert plate 201 is inserted into the slot 303, the seat hole 2013 can be axially overlapped with the flow hole 302. Figure 5 As shown; during the distillation process, liquid and gas can pass through the seat hole 2013 and the flow hole 302 through the filler mesh 203 and the catalyst mesh box 204 for catalytic reaction.

[0042] Slide grooves 304 are further provided on both sides of the slot 303 ; the guide protrusions 2012 can be cooperatively arranged in the slide grooves 304 .

[0043] Specifically, a handle 2016 is further provided on one side of the plate body 2011 .

[0044] Specifically, the catalyst mesh box 204 includes: a box body 2041 , on which a cover plate 2042 is provided.

[0045] Specifically, in this embodiment, the number of catalytic components 2 is 2 groups.

[0046] The specific use principle of the utility model is as follows:

[0047] When replacing the catalyst, first, the catalytic component 2 is transported to the installation position by manual equipment, and then the catalytic component 2 pre-installed with the catalyst is inserted into the catalytic chamber 3 through the slot 303 by manual lifting equipment. The guide wheel 2015 cooperates with the slide groove 304 to make the installation process of the plug-in plate 201 more labor-saving. After the plug-in plate 201 is installed in place, the seat hole 2013 and the flow hole 302 are axially aligned to form a complete flow channel. Then, the sealing airbag 202 is inflated through the air source interface, so that it expands between the plug-in plate 201 and the inner wall of the catalytic chamber to form an airtight interface to ensure the airtightness of the reaction chamber.

[0048] During the distillation process, the distillation gas enters the catalytic chamber 3 through the lower tower body 1, and then passes through the channel formed by the flow hole 302 and the seat hole 2013, and enters the upper tower body 4 upward; the distillation liquid passes through the catalytic chamber 3 and the catalytic assembly 2 downward from the upper tower body 4 and enters the lower tower body 1. The distillation gas first contacts the packing net 203, whose grid structure evenly disperses the gas, and then penetrates upward the tightly packed catalyst layer in the catalyst net box 204. In this process, the packing net 203 and the catalyst net box 204 work together to ensure that the gas-liquid two-phase material is fully in contact with the catalyst particles, completing an efficient catalytic reaction.
