Description

Technical Field

[0001] The utility model relates to the technical field of drying equipment, in particular to a flow-added flue gas drying tower. Background Art

[0002] Dehydration is a common process in the chemical industry. Commonly used dehydration methods mainly include three categories: low-temperature dehydration method, solid desiccant adsorption method and solvent absorption method. Among them, the solid desiccant adsorption method can specifically include silica gel method and molecular sieve method. The molecular sieve method is more commonly used because of its advantages such as strong adsorption selectivity and high adsorption characteristics under low water vapor partial pressure. The molecular sieve method mainly uses a drying tower to achieve the purpose of dehydration.

[0003] Existing drying towers are generally filled with zeolites to dry the gas. The air inlet and air outlet of the drying tower are respectively arranged at the top and bottom of the drying tower. The gas enters the drying tower from the air inlet, moves from top to bottom, passes through the zeolite, and is discharged from the air outlet to complete the drying process. Since the gas moves from top to bottom in the drying tower, the drying time of the gas in the drying tower is insufficient, resulting in poor drying effect of the drying tower.

[0004] Therefore, it is necessary to design a flow-added flue gas drying tower which is highly practical and can increase the gas drying time. Utility Model Content
