[0032] It should be noted that the pressure gauge port 240 is a threaded interface or a flange interface, which needs to be matched with the joint of the pressure gauge, and the upper head 200 is a top closed structure of the cylinder 100, and the pressure gauge port 240 is arranged at this position, and the reasons include that the pressure of the gas or steam medium is more easily and accurately measured at the upper part (avoiding the interference of liquid deposition); it is convenient for installation and observation (there is more sufficient space for high-position operation).
[0033] In some embodiments, the steam jacket nozzle 150 is opened on the side wall of the cylinder 100 close to the bottom, and a double-layer sleeve structure (the inner pipe conveys steam, and the outer jacket layer can be used for heat preservation or heating) is adopted; the steam directly enters the inside of the cylinder 100 through the inner pipe, and the jacket layer introduces an auxiliary heat source (such as low-pressure steam or electric heating), so as to prevent the main steam from condensing in the conveying process and ensure that the steam efficiently enters the cylinder 100 in a gaseous state.
[0034] It should be noted that the first manhole 210 is used for equipment maintenance and internal cleaning, and the second manhole 310 is used for residual cleaning; the spray port 220 is used for installing a spray pipe and a spray head to uniformly spray liquid (such as a solvent, a washing liquid or a cooling liquid) into the inside of the cylinder 100, to assist the stripping process, the liquid enters through the spray port 220, is atomized or dispersed through the spray head, forms uniform liquid droplets, covers the cross section of the cylinder 100, so as to enhance the gas-liquid contact efficiency, promote mass transfer (such as removing volatile components), or control the temperature in the inside of the cylinder 100 (such as spraying a cooling or heating medium), to prevent local coking or plugging.

[0035] It should be noted that the core function of the stripping tower provided in the present application includes: separation of volatile substances: using countercurrent contact of steam and liquid to vaporize the light components in the liquid and discharge them with the gas phase; temperature control: maintaining the process temperature by heating the cylinder 100 through the steam jacket, improving the stripping efficiency; safety protection: preventing flammable, explosive or oxidation risks through nitrogen protection (inertization) and safety valve design; operation monitoring: real-time monitoring of liquid level and pressure to ensure stable operation.
[0036] In some embodiments, the first liquid level meter and the second liquid level meter are arranged at 20% and 80% of the height of the cylinder 100.
[0037] In the present application, the stripping tower is a chemical equipment for gas-liquid mass transfer separation, mainly used for removing volatile components (such as light hydrocarbons, dissolved gases or organic pollutants) in the liquid through steam stripping process. Steam is introduced into the inside of the cylinder 100 through the steam jacket (steam inlet), and the direct contact of steam and liquid raw materials vaporizes and separates the volatile target components (such as light hydrocarbons, dissolved gases or solvents) in the liquid.

The sprayed liquid and the dropped raw material are mixed in the baffle plate 110 area. Steam heats the cylinder 100 through the jacket, and the stripped gas phase is discharged from the gas phase port 270, and the liquid is discharged from the liquid outlet 320; steam jacket nozzle 150: indirect control of cylinder 100 temperature through jacket heating (rather than direct steam injection), reducing the dilution effect on the raw material, while improving the utilization rate of heat energy. Through this arrangement, the present application has the advantages of compact structure, high mass transfer efficiency, safe operation and easy maintenance, and can effectively improve the liquid level control accuracy.
