Abstract
Description
Technical Field
[0001] This utility model relates to a polyester process tower. Background Technology
[0002] Process towers play a crucial role in polyester production. In actual production, the gas phase pipelines of process towers become increasingly clogged over time. In order to confirm the internal condition of the process tower and ensure that the liquid level in the process tower is not too low or too high, sight glasses need to be installed on the process tower. However, sight glasses are prone to blurring, which makes it impossible for operators to see the internal condition of the tower, which is not conducive to subsequent liquid level adjustment and can easily lead to production accidents. Utility Model Content
[0003] The purpose of this invention is to solve the problem that blurry sight glasses in existing process towers prevent operators from clearly seeing the internal conditions of the tower, thus hindering liquid level adjustment. This invention proposes a polyester process tower that uses a spray assembly to spray ethylene glycol onto the sight glass, thereby cleaning the glass and enabling effective observation of the tower's internal conditions. This allows operators to precisely adjust the liquid level within the tower, resulting in more stable production and significantly reducing the probability of production accidents.

[0011] Preferably, the connector is a tee connector.
[0012] Preferably, the tower body is provided with a buckle that connects to the diversion pipe.
[0013] In summary, the advantages of this invention are as follows: First, by spraying ethylene glycol onto the sight glass through the spray assembly, the sight glass is cleaned, allowing for effective observation of the internal condition of the process tower. This enables operators to precisely adjust the liquid level within the tower, resulting in more stable production and significantly reducing the probability of production accidents. Second, by fixing the spray assembly to the tower body using a fixing component, the spray assembly can be stably fixed to the tower body, preventing displacement during spraying and ensuring uniformity and improved spraying efficiency. Finally, the ethylene glycol in the feed pipe is transported to the spray assembly through a diversion pipe, eliminating the need for an additional raw material supply structure connected to the spray assembly. The opening and closing of the diversion pipe is effectively controlled by a ball valve, which is simple to operate; simply rotating the valve stem completes the opening and closing action, simplifying the operator's workload and reducing ethylene glycol waste.

[0019] like Figure 1 and Figure 2 As shown, a polyester process tower includes a tower body 1, a distribution pipe 4, and a sight glass 2 disposed on the tower body 1. A feed pipe 3 for conveying ethylene glycol to the tower body 1 is connected to the tower body 1. A ball valve 41 is provided on the distribution pipe 4. One end of the distribution pipe 4 is connected to the feed pipe 3, and the other end of the distribution pipe 4 is provided with a connector 42. A spray assembly 5 for spraying ethylene glycol onto the sight glass 2 is provided on the connector 42. A fixing assembly 6 for fixing the spray assembly 5 is provided on the tower body 1.
[0020] Ethylene glycol is sprayed onto the sight glass by the spray assembly, effectively cleaning the sight glass and allowing for precise observation of the internal condition of the process tower. This enables operators to accurately adjust the liquid level within the tower, resulting in more stable production and significantly reducing the probability of production accidents. Secondly, the spray assembly is fixed to the tower body by a fixing component, ensuring its stable fixation during spraying and preventing displacement, thus guaranteeing uniformity and improving spraying efficiency. Finally, ethylene glycol from the feed pipe is delivered to the spray assembly via a diversion pipe, eliminating the need for an additional raw material supply structure connected to the spray assembly. The opening and closing of the diversion pipe is effectively controlled by a ball valve, which is simple to operate; simply turning the valve stem completes the opening and closing action, simplifying the operator's workload and reducing ethylene glycol waste.
[0021] The spray assembly 5 includes a connecting pipe 51 and a nozzle 52. One end of the connecting pipe 51 is connected to the connector 42, and the nozzle 52 is disposed at the other end of the connecting pipe 51. In this embodiment, the nozzle is a spray-type nozzle, which can achieve uniform rinsing of the sight glass, further improving the cleaning effect. The connecting pipe ensures that the nozzle can be quickly installed on the connector. The overall structure is simple and easy to install and disassemble. The horizontal axis of the nozzle 52 coincides with the horizontal axis of the sight glass 2, ensuring that the ethylene glycol sprayed by the nozzle can accurately cover the field of view of the sight glass, which helps to improve the cleaning effect. The distance from the nozzle 52 to the sight glass 2 is L, and L = 9~12cm. In this embodiment, L is preferably 10cm to ensure that the ethylene glycol sprayed by the nozzle can be accurately sprayed onto the sight glass, thereby avoiding waste of ethylene glycol.
[0022] The fixing component 6 includes a fixing frame 61 and a fixing sleeve 62 disposed on the fixing frame 61. The fixing frame 61 is disposed on the tower body 1, and the connecting pipe 51 is disposed on the fixing sleeve 62. The fixing frame 61 is provided with a support rod 63 for supporting the nozzle 52. The fixing component is configured as a fixing frame and a fixing sleeve. The fixing sleeve and the support rod can ensure that the connecting pipe and the nozzle are stably installed on the fixing frame, preventing the nozzle from shaking or shifting during the spraying process, and ensuring the stability of the nozzle operation. The fixing frame 61 includes a vertical part 64 and a horizontal part 65. The horizontal part 65 is located at the top of the vertical part 64, and the vertical part 64 is fixedly connected to the tower body 1. The horizontal part 65 is provided with a connecting rod 66 connected to the fixing sleeve 62, and a reinforcing rib 67 is provided between the vertical part 64 and the horizontal part 65. By setting the fixing frame with a vertical and horizontal part, since the vertical part is fixedly connected to the tower body, the contact area between the fixing frame and the tower body can be increased, improving the overall installation quality of the fixing frame. Secondly, the connecting rod on the horizontal part connected to the fixing sleeve prevents the spray assembly from causing spatial interference with the installation of the fixing frame. In this embodiment, the connecting rod and support rod can be set as a telescopic structure to facilitate adjustment of the height of the spray assembly on the fixing frame and meet different spraying needs. Finally, the setting of the reinforcing rib can improve the installation strength of the entire fixing frame. The fixing frame 61 is an integral structure, which simplifies the installation process between the various components of the fixing frame and improves the overall installation strength of the fixing frame.
[0023] The connector 42 is a T-connector. In this embodiment, the T-connector is a T-type connector, which allows the connector to connect two sets of spray components simultaneously, thereby achieving the effect of cleaning two sight glasses at the same time. The tower body 1 is provided with a buckle 7 connected to the diversion pipe 4, which can stably fix the diversion pipe to the tower body. The buckle is existing technology, and its specific structure will not be described in detail in this embodiment. The buckle is fixed to the tower body by expansion screws.
[0024] In addition to the preferred embodiments described above, there are other embodiments of this utility model. Those skilled in the art can make various changes and modifications based on this utility model. As long as they do not depart from the spirit of this utility model, they should all fall within the scope defined by the appended claims.
