Description

Technical Field

[0001] The utility model relates to the technical field of reflux tanks, and more specifically to a reflux tank of a low-carbonic acid recovery tower. Background Art

[0002] Reflux refers to the process in which the rising steam from the top of the catalytic distillation tower is condensed by the condenser, and part of the liquid flows out of the distillation tower as distillate, while the other part of the liquid is sent back to the distillation tower through the reflux tank. The reflux tank is a container used in the petrochemical field at a fixed position for the main purpose of medium storage, and also has the functions of buffering, metering, stirring, mixing and separation. Typical reflux tanks include vertical reflux tanks and horizontal reflux tanks.

[0003] Most of the existing horizontal reflux tanks are sealed by integral welding. After long-term reflux operation, residues will accumulate inside the reflux tank. Since the tank body is welded as a whole, it is inconvenient to clean the inside. In view of this, we propose a low carbonic acid recovery tower reflux tank. Utility Model Content

[0024] See also Figure 1-Figure 2 , the utility model provides a technical solution:

[0025] A low-carbonic acid recovery tower reflux tank comprises a tank body 1; a sealing assembly 2 connected to the left side of the tank body 1 by a hinge 3; a support assembly 4 arranged at the bottom of the tank body 1; a bolt 5 installed at the connection end between the sealing assembly 2 and the tank body 1; and a suspension fastener 6 arranged at the top of the tank body 1. The tank body 1 and the suspension fastener 6 are a welded integral structure, and a plurality of flanges are provided on the tank body 1 for connecting pipes. The utility model provides the sealing assembly 2 and the hinge 3 so that the tank body 1 as a whole is no longer welded and sealed, and the sealing assembly 2 can be connected to the tank body 1 by the hinge 3. When cleaning the inside of the tank body 1, the bolt 5 between the sealing assembly 2 and the tank body 1 can be removed to open the sealing assembly 2, which is convenient for cleaning the inside of the tank body 1 and makes the inside tidy.

[0026] Specifically, the sealing assembly 2 includes a sealing cover 201, which is connected to the flange on the left side of the tank body 1 through a hinge 3; a handle 202, which is arranged on the outside of the sealing cover 201; a discharge pipe 203, which is connected to the lower end of the sealing cover 201; a flange 204, which is arranged on the sealing cover 201 close to the side of the tank body 1; and a sealing plugging ring 205, which is arranged on the inner side of the flange 204. The sealing cover 201 is fitted with the tank body 1 through the flange 204, and the sealing plugging ring 205 forms a snap-fit ​​structure with the tank body 1 through the flange 204. The utility model uses the sealing plugging ring 205 to seal the connection between the sealing cover 201 and the tank body 1, improves the overall sealing performance, and prevents leakage at the connection between the two. At the same time, the sealing cover 201 is fixed by bolts 5 after being connected to the tank body 1 through the flange 204, which can improve the stability of the overall connection.

[0027] In addition, the support assembly 4 includes two connecting plates 401, which are symmetrically welded to the bottom of the tank body 1; a support plate 402, which is arranged at the bottom of the connecting plate 401; and a bottom plate 403, which is welded to the bottom of the support plate 402. The utility model provides the connecting plate 401, which is in an arc shape and can be welded to the bottom of the tank body 1. The connecting plate 401, the support plate 402 and the bottom plate 403 are welded into an integrated structure, and the support stability is relatively high.

[0028] Working principle: After the reflux liquid refluxes from the catalytic distillation tower, it enters the tank body 1 through the connecting pipe. After long-term use, impurities will be precipitated and accumulated at the bottom of the inner cavity of the tank body 1. When there are too many impurity precipitates, the sealing cover 201 can be opened to clean the inside of the tank body 1. First, the liquid inside the tank body 1 is discharged through the discharge pipe 203 on the sealing cover 201, and then the bolts 5 on the flange 204 are manually unscrewed one by one, and then the handle 202 is manually pulled to open the sealing cover 201, and then the impurities precipitated inside the tank body 1 are cleaned with a cleaning tool. After cleaning, the sealing cover 201 is buckled on the tank body 1, and then the bolts 5 are reinstalled to fix it.

[0029] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model.
