Description

Technical Field

[0001] This application relates to the field of light-weight removal towers, and in particular to an optimization device for the reflux of condensate at the top of a light-weight removal tower. Background Technology

[0002] A light component removal tower is a type of chemical equipment primarily used to remove light components from mixtures. It utilizes the difference in volatility of substances to achieve separation. In the production of N-methylpyrrolidone, a light component removal tower is used to remove the monomethylamine produced in the reaction. A light component removal tower typically includes a mixer, preheater, reactor, and distillation system. The reactor is a high-pressure tubular reactor, using electrically heated heat transfer oil to control the reaction temperature. The reaction products enter the distillation system for distillation, first passing through the light component removal tower. The product is methylamine and then enters a light component removal tower for further processing. The concept and technology of light component removal towers have wide applications in the chemical industry. With the development of chemical technology, the design and operation of light component removal towers are constantly optimized to improve separation efficiency and reduce energy consumption. In conventional light component removal towers, the reaction products are placed into the tower body for distillation. The distilled light components enter the next processing stage through the connecting pipe, which facilitates the separation of reaction products. An observation window is installed on the surface of the light component removal tower body to facilitate the observation of the usage status of the tower body.

[0003] Regarding the aforementioned technologies, the inventors believe that when using a conventional light-weight removal tower, the vapor generated during distillation tends to condense into liquid at the top of the tower body. This can easily lead to condensation of the condensate on the inner wall of the connecting pipe, reducing the inner diameter of the connecting pipe and thus affecting the smoothness of the exhaust from the light-weight removal tower's connecting pipe.

[0004] The information disclosed in this background section is only intended to enhance the understanding of the background technology of this application, and therefore may include prior art that is not known to those skilled in the art. Utility Model Content

[0022] The following is in conjunction with the appendix Figure 1 —4. This application will be described in further detail.

[0023] This application discloses an optimized device for reflux of condensate from the top of a light-weight removal tower, referring to... Figure 1 - Figure 2The system includes a light-weight removal tower body 1. During use, the reaction products are placed inside the light-weight removal tower body 1 for distillation. The distilled light components enter the next processing stage through the connecting pipe 2, facilitating the separation of the reaction products. An observation window 3 is installed on the surface of the light-weight removal tower body 1 to facilitate the observation of the usage status inside the light-weight removal tower body 1. A fixing ring 4 is connected to the inner wall of the light-weight removal tower body 1. A sliding groove 5 is opened at the top of the fixing ring 4. A rotating ring 6 is installed on the inner wall of the sliding groove 5 through a rotating ball 7. The surface of the rotating ring 6 is rotatably connected to the inner wall of the light-weight removal tower body 1, and a reflux plate 10 is installed on the inner wall of the rotating ring 6. The reflux plate 10 is used to block the condensate. After the rotating ring 6 rotates, the rotating ball 7 moves up and down with the help of the auxiliary block 8, thereby vibrating and removing the condensate on the surface of the reflux plate 10, effectively improving the convenience of the light-weight removal tower and avoiding the problem of condensate condensation clogging the connecting pipe 2.

[0024] Reference Figure 2 Several rotating beads 7 are rotatably connected at one end to the surface of the rotating ring 6. The rotating beads 7 reduce the friction between the rotating ring 6 and the fixed ring 4, making it easier for the rotating ring 6 to rotate inside the light-light removal tower 1. A rotating turbine 9 is fixedly installed at the bottom of the rotating ring 6. The surface of the rotating turbine 9 rotates with the bottom of the fixed ring 4. The rotating turbine 9 is controlled by the rising airflow generated during the distillation of the light-light removal tower 1, which facilitates the control of the rotation of the rotating ring 6 and reduces the energy consumption of the device. An inverted cone-shaped reflux plate 10 is installed on the inner wall of the rotating ring 6. The inverted cone-shaped reflux plate 10 facilitates the backflow of condensate into the light-light removal tower 1, preventing condensate from accumulating on the surface of the reflux plate 10 and affecting the steam flow.

[0025] Reference Figure 2 - Figure 4 Several fixing bolts 12 are installed on the top of the reflux plate 10. The surface of the fixing bolts 12 is fitted with a mounting bracket 11. The fixing bolts 12 facilitate the installation and removal of the reflux plate 10, so that the reflux plate 10 can be cleaned after long-term use. The top of the mounting bracket 11 is connected to a push spring 14. The top of the push spring 14 is connected to the inner wall of the light removal tower body 1 through the fixing bracket 13. The spring pushes the mounting bracket 11, so that the rotating ring 6 at the bottom of the mounting bracket 11 is kept connected to the fixing ring 4. This avoids the situation where the rotating ring 6 is stuck at the top of the tower, making it difficult for the rotating ball 7 to contact the auxiliary block 8. A bearing 15 is connected between the push spring 14 and the mounting bracket 11. The bearing 15 reduces the friction between the push spring 14 and the mounting bracket 11, making it more convenient for the rotating ring 6 to rotate.

[0026] The implementation principle of the condensate reflux optimization device at the top of the light-light weight removal tower in this application embodiment is as follows: A fixed ring 4 is connected to the inner wall of the light-light weight removal tower body 1. A groove 5 is provided at the top of the fixed ring 4. A rotating ring 6 is installed on the inner wall of the groove 5 via rotating beads 7. The surface of the rotating ring 6 is rotatably connected to the inner wall of the light-light weight removal tower body 1, and a reflux plate 10 is installed on the inner wall of the rotating ring 6 to shield the condensate. After the rotating ring 6 rotates, the rotating beads 7 move up and down with the help of an auxiliary block 8, thereby vibrating and removing the condensate on the surface of the reflux plate 10, avoiding the problem of condensate condensation and clogging of the connecting pipe 2. One end of several rotating beads 7 is rotatably connected to the surface of the rotating ring 6 to facilitate… The friction between the rotating ring 6 and the fixed ring 4 is reduced by the use of the rotating bead 7, which makes it easier for the rotating ring 6 to rotate inside the light-light removal tower body 1. A rotating turbine 9 is fixedly installed at the bottom end of the rotating ring 6. The surface of the rotating turbine 9 rotates with the bottom end of the fixed ring 4, so that the rotating turbine 9 can be controlled by the rising airflow generated during the distillation of the light-light removal tower body 1, which facilitates the control of the rotation of the rotating ring 6 and reduces the energy consumption of the device. The inverted cone-shaped reflux plate 10 is installed on the inner wall of the rotating ring 6, so that the condensate can flow back into the light-light removal tower body 1, avoiding the condensate from accumulating on the surface of the reflux plate 10 and affecting the steam flow.

[0027] Several fixing bolts 12 can also be installed on the top of the reflux plate 10. The surface of the fixing bolts 12 is fitted with a mounting bracket 11, so that the reflux plate 10 can be easily installed and removed with the fixing bolts 12, so that the reflux plate 10 can be cleaned when it is used for a long time. The top of the mounting bracket 11 is connected to a push spring 14. The top of the push spring 14 is connected to the inner wall of the tower body 1 of the light removal tower with the help of the fixing bracket 13, so that the spring can push the mounting bracket 11, thereby keeping the rotating ring 6 at the bottom of the mounting bracket 11 connected to the fixing ring 4, avoiding the situation where the rotating ring 6 is stuck at the top of the tower, making it difficult for the rotating ball 7 to contact the auxiliary block 8. A bearing 15 is connected between the push spring 14 and the mounting bracket 11, so that the friction between the push spring 14 and the mounting bracket 11 can be reduced with the help of the bearing 15, making it more convenient when the rotating ring 6 rotates.
