Description

Technical Field

[0001] The invention relates to the technical field of distillation towers, and in particular to a distillation system for chemical production and processing. Background Art

[0002] A distillation tower is a tower-type gas-liquid contact device for distillation. It uses the different volatilities of the components in the mixture to transfer the light components in the liquid phase to the gas phase, and the heavy components in the gas phase to the liquid phase, thereby achieving the purpose of separation.

[0003] After a long period of distillation work, the existing distillation system is prone to excessive accumulation of impurities, which will clog the sieve holes on the sieve plate, affecting the flow of gas through the sieve holes, thereby reducing the distillation efficiency. Therefore, a corresponding cleaning mechanism is often equipped to clean the sieve holes. However, when cleaning the sieve holes, the existing cleaning mechanism uses a driving assembly to drive the cleaning component to clean the sieve holes one by one. This cleaning method is inefficient and is not conducive to quickly completing the cleaning of all the sieve holes on the sieve plate. It is also easy to affect the gas flow efficiency through the sieve holes, reducing the distillation efficiency. In addition, there is a lack of collection of cleaned impurities, which makes it easy for impurities to accumulate on the lower sieve plate or the bottom of the shell, affecting the circulation of the bottom liquid and reducing the distillation efficiency.

The fan sucks steam from below the tower plate through the bottom opening of the mounting shell, and inputs it into the axial cavity of the rotating rod, and finally discharges it horizontally through the connecting groove and multiple air outlet pipes on the mounting bar, thereby accelerating the circulation of steam.

[0024] 3. The present invention sets up a clearing mechanism, and the cleaning component in the hole moves to the through hole that needs to be cleaned. The second electric telescopic rod works, and under the cooperation of the embedded rod and the spiral guide groove, the transmission block is pushed and rotated at the same time, so that the cross-shaped scraper rotates and presses down into the through hole, which can scrape off the impurities inside the through hole and on the inner wall.

[0025] 4. The present invention sets a clearing mechanism. When the mounting bar and the moving block rotate, the impurities inside and on the inner wall of the through hole, as well as the impurities accumulated and adsorbed on the upper surface of the tower plate can be pushed to the vicinity of the slag discharge hole, thereby improving the cleaning and dredging effect of the tower plate. Through the slag discharge control component, the slag discharge hole is opened when the moving block pushes the impurities to the slag discharge hole, and the slag discharge hole is closed when the moving block moves away from the slag discharge hole, so that the impurities are quickly discharged from above the tower plate through the slag discharge hole. Through layer-by-layer cleaning, the impurities will gather at the lower end of the outer shell. As the raw liquid circulates, the impurities in the raw liquid can be filtered and collected through the filter. BRIEF DESCRIPTION OF THE DRAWINGS

[0059] The slag discharge control assembly 7 includes an arc plate 71, which is fixedly connected to the side of the tower plate 9, and a slag discharge channel is formed between the arc plate 71 and the inner wall of the shell 1. A slag discharge hole 711 is opened on the arc plate 71, and a slanted plate 72 is fixedly connected to the side of the arc plate 71 close to the slag discharge channel. The slanted plate 72 is located above the slag discharge hole 711. A first electric telescopic rod 73 is installed at the bottom of the slanted plate 72, and a blocking plate 74 is fixedly connected to the output end of the first electric telescopic rod 73. Both ends of the blocking plate 74 are fixedly connected to first trapezoidal slide bars 75. The two first trapezoidal slide bars 75 are slidably connected to the arc plate 71. After the blocking plate 74 moves downward, it is tightly closed. The slag discharge hole 711 is sealed, and a first pressure sensor 76 and a second pressure sensor 77 are installed on the side of the arc plate 71 away from the slag discharge channel. The first pressure sensor 76 and the second pressure sensor 77 are located on both sides of the slag discharge hole 711. After the moving block 83 rotates, it first contacts the second pressure sensor 77 and then contacts the first pressure sensor 76. The first pressure sensor 76, the second pressure sensor 77 and the first electric telescopic rod 73 are all electrically connected to a controller, which is installed on the housing 1. The controller is used to receive the first pressure sensor 76 and the second pressure sensor 77, and control the working state of the first electric telescopic rod 73.

[0060] In the present invention, the stock solution is added into the housing 1 through the feed pipe 3, and the stock solution can pass through the through hole 91 on the plate 9 and fall to the bottom of the housing 1, and enter the filter 5, and the stock solution is filtered by the filter 5, and then the filtered stock solution is processed into steam by the reboiler 61 and then re-introduced into the housing 1;

[0061] The steam will rise through the through hole 91. During this process, the light components in the raw liquid will turn into steam and rise to the top of the shell 1. Then the steam will enter the condensation part 21 to condense. The condensate will reflux through the reflux part 23. The refluxed liquid will flow down along the tower plate 9 in an arc shape. By setting the tower plate 9 as a plate-shaped structure with a convex middle part, and the through hole 91 is opened perpendicular to the inclined surface of the tower plate 9, the steam bubbles will be discharged obliquely when passing through the through hole 91. Compared with the vertical discharge of the bubbles, the time of the bubbles in the raw liquid can be extended to a certain extent. After a period of time, part of the condensate will reflux through the reflux part 23, and the other part will be discharged through the top liquid outlet 22.

[0062] When in use, the raw liquid will gather above the three groups of trays 9, and the raw liquid above the arc-shaped plate 71 will fall to the next layer. The fan 814 works, and its input end draws steam from below the tray 9 through the bottom opening of the mounting housing 812, and inputs it into the shaft cavity of the rotating rod 811;

[0063] The motor 42 is working, and its output end drives the three groups of rotating rods 811 to rotate through the bevel gear transmission part 43. The rotation of the rotating rod 811 drives the mounting bar 821 to rotate. When the mounting hole 822 on the mounting bar 821 does not coincide with the through hole 91 on the tower plate 9, the gas in the axial cavity of the rotating rod 811 can be discharged horizontally through the connecting groove 823 and the multiple gas outlet pipes 85. On the one hand, it can accelerate the circulation of steam. On the other hand, the bubbles discharged horizontally through the gas outlet pipe 85 can impact the bubbles discharged from the through hole 91, thereby changing the movement trajectory of the bubbles discharged from the through hole 91, which can prolong the residence time of the bubbles in the raw liquid, thereby prolonging the contact time of the gas-liquid two phases inside the distillation tower, and can increase the efficiency of gas-liquid mass transfer inside the distillation tower.

[0064] When the mounting bar 821 rotates, the through holes 91 arranged on the same circumference are distributed at intervals of 30 degrees, so that the alignment of the cleaning component 84 in the hole and the through holes 91 can be controlled by the rotation of the motor 42. The mounting bar 821 and the moving block 83 are both rotated 30 degrees by the motor 42, so that the multiple mounting holes 822 on the mounting bar 821 coincide with the multiple through holes 91 on the same busbar on the tower plate 9;

[0065] When the second electric telescopic rod 841 is working, its output end is extended. Since the embedded rod 844 is embedded in the spiral guide groove 824, when the output end of the second electric telescopic rod 841 is extended and pushes the transmission block 842 to move, it will drive the cross-shaped scraper 843 to rotate. The lower end of the cross-shaped scraper 843 is set as a pointed end, which is more convenient to be embedded in the impurities blocked inside the through hole 91. By rotating and pressing down the cross-shaped scraper 843, the impurities inside the through hole 91 and on the inner wall can be scraped off.

[0066] Impurities can fall onto the next layer of the tray 9. As the mounting bar 821 rotates, the impurities accumulated and adsorbed on the upper surface of the tray 9 will be scraped off by the mounting bar 821 and the moving block 83. Since the outer side of the tray 9 is tilted downward, the impurities will settle close to the moving block 83.

[0067] By setting the spring 826, the moving block 83 can move to adapt to the curvature of the curved plate 71 when it moves to the position of the curved plate 71. When the moving block 83 moves to the position of the second pressure sensor 77, the second pressure sensor 77 detects that the pressure exceeds the threshold, and the first electric telescopic rod 73 is controlled to work, and its output end contracts to make the blocking plate 74 move upward, so that the slag discharge hole 711 is exposed. At this time, the impurities at the position of the moving block 83 can enter the slag discharge channel through the slag discharge hole 711 together with the raw liquid and fall downward;

[0068] When the moving block 83 moves to the position of the first pressure sensor 76, the first pressure sensor 76 detects that the pressure exceeds the threshold, and then the output end of the first electric telescopic rod 73 is controlled to extend so that the blocking plate 74 closes the slag discharge hole 711;

[0069] Therefore, when the moving block 83 rotates and sweeps across the arc plate 71, the impurities precipitated on the tower plate 9 and the impurities inside the through hole 91 can be cleaned up, so as to avoid the through hole 91 being blocked, which makes it difficult for steam to flow and affects the chemical distillation process. Through layer-by-layer cleaning, the impurities will gather at the lower end of the outer shell 1. As the raw liquid circulates, the impurities in the raw liquid can be filtered and collected through the filter 5.

[0070] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
