Gas-liquid absorption tower for pharmaceutical and chemical production

Abstract

The invention discloses a gas-liquid absorption tower for pharmaceutical and chemical production. The absorption tower comprises an absorption tower main body and a protection mechanism, the outer wall of the top end of the absorption tower main body is fixedly connected with a liquid inlet pipe, the outer wall of the bottom end of the absorption tower main body is fixedly connected with a liquidoutlet pipe, gas inlet pipes are fixedly connected to the surfaces of the two sides of the absorption tower main body, the top surface of the absorption tower main body is fixedly connected with a gasoutlet pipe, the liquid inlet pipe, the liquid outlet pipe, the gas inlet pipe and the gas outlet pipe are all communicated with the interior of the absorption tower main body, the protection mechanism comprises a protection base, the protection base is mounted in ports of the gas inlet pipes, through holes are formed in the end surface of the protection base, and the through holes are communicated with the interior of the gas inlet pipes. The designed protection base is fixed in the ports of the gas inlet pipes, so rubber balls are contracted into a storage groove under the action of gas thrust in use, and the rubber balls seal the through holes of the protection base under the pushing of a fixing spring when not in use.

Description

technical field [0001] The invention belongs to the technical field of pharmaceutical production, and in particular relates to a gas-liquid absorption tower for pharmaceutical and chemical production. Background technique [0002] The absorption tower is the equipment to realize the absorption operation. The absorbent is added from the top of the tower and flows from top to bottom, and contacts with the gas flowing from the bottom to the top. The liquid that has absorbed the absorbent is discharged from the bottom of the tower, and the purified gas is discharged from the top of the tower. The gas-liquid absorption towers currently on the market still have various deficiencies and cannot meet the needs of production and life. [0003] For example, the inlet pipe of the existing gas-liquid absorption tower is not easy to close and seal when it is not in use. Therefore, we propose a gas-liquid absorption tower for pharmaceutical and chemical production. Contents of the invent...
