Liquid dehumidification cross-flow packed tower

Abstract

The invention discloses a liquid dehumidification cross-flow packed tower which comprises a cross-shaped packed tower body. The interior of the packed tower body is of a cavity structure. The upper portion of the packed tower body is covered with a top cover, a liquid spray pipe is arranged on the top cover, and a liquid distribution plate is arranged at the position, below the top cover, in the packed tower body. A packing cavity is formed in the position, under the liquid distribution plate, in the packed tower body, the packing cavity is formed in the cross position of the cross-shaped packed tower body, and a matched drawer type packing frame is arranged in the packing cavity, and filled with paper corrugated packing. According to the liquid dehumidification cross-flow packed tower, the packing can be replaced conveniently and fast, structural damage to the packing is avoided, the repeated utilization rate of the paper corrugated packing is improved, meanwhile, comparison testing on different kinds of packing on the same packed tower under the same work condition is possible, and on the one hand, the data accuracy of comparison testing is improved; on the other hand, equipment cost is saved.

Description

technical field [0001] The invention relates to the field of heat-humidity decoupling for air conditioning, in particular, it is suitable for the cross-flow heat and mass transfer process of solution dehumidification or solution regeneration. Background technique [0002] Dehumidifiers and regenerators are the key components of solution dehumidification systems. Packed tower dehumidifiers and regenerators can provide a large gas-liquid contact area, and are currently the most studied solution dehumidifiers and regenerators. Because there is no other cold and heat source involved in the heat and mass transfer process of the solution and air in the packed dehumidifier and regenerator, they all belong to the adiabatic dehumidification / regeneration process. The direct contact between the solution and the air in the filler has sensible heat exchange under the action of the temperature difference. The change of the solution temperature will lead to the change of the partial pressu...
