After the improvement of the utility model, when there is a gas leak at the steam pipe connection port, the user can also quickly know and take timely measures, thereby effectively reducing the waste of resources and improving the practicality of the activated carbon adsorption steam desorption equipment.

[0025] like Figure 3 As shown, an internal thread is provided on the inner side surface of the external connection alarm ring 13, which can be matched with the thread on the outer side of the connecting flange 11.

After separation, the organic solvent is recovered, and the water can be discharged or further processed. This design ensures the effective recovery of the organic solvent, reduces resource waste, and also meets environmental protection requirements.

[0030] During operation, the adsorption process involves exhaust gas passing through drying fan 7 and filter 6 before entering activated carbon filter adsorption tank 1. After being adsorbed by activated carbon layer 3 in the tank, harmful components are removed. Purified gas that meets emission standards is discharged from the bottom of the tank and discharged outdoors via main exhaust fan 8. The desorption and regeneration process involves regenerating the activated carbon layer 3 after it has absorbed a certain amount of solvent over a period of time. During regeneration, steam is injected from the bottom of the tower to evaporate the solvent from the adsorbent in the activated carbon layer 3. The liquid is then condensed in condenser 9 and enters separation storage 10, where the organic solvent is separated and recovered. The residual liquid is then aerated and discharged.
