Solution dehumidifying and regenerating device

Abstract

The invention discloses an internal cold/internal heat type solution dehumidifying and regenerating device. A plurality of zigzag connected heat and mass transfer units consisting of reducing templates (2) and internal cold/internal heat pipes (1) are arranged in a shell (10), an inlet pipe (7) is arranged above the shell, and an outlet pipe (8) is arranged below the shell; a dehumidifying solution inlet pipe (5) is arranged above the heat and mass transfer units, a solution distributor (6) is arranged on the dehumidifying solution inlet pipe (5), and the bottom of the shell (10) is provided with a dehumidifying and regenerating solution delivery pipe (9). A dehumidifying solution flows into a pipeline through a solution inlet header pipe and is sprayed to the reducing templates to be in direct contact with wet air for carrying out a heat and mass transfer process so that the purpose of air dehumidifying or solution regenerating is achieved; and internal heat/internal cold branch pipes play a role of strengthening the heat and mass transfer process, thus the solution dehumidifying and regenerating efficiency is greatly improved. The internal cold/internal heat type solution dehumidifying and regenerating device has the advantages of simple machining process, low cost and easiness in production and manufacture.

AI Technical Summary

Problems solved by technology

However, as the dehumidification or regeneration process proceeds, the temperature of the solution gradually increases (dehumidification process) or decreases (regeneration process), so the mass transfer potential difference between the solution and the humid air gradually decreases, which is not conducive to the relationship between the solution and the humid air. heat and mass exchange

Some use traditional plate-fin or tube-fin heat exchangers to make internal cooling or internal heating dehumidifiers, but the solution usually has a corrosive effect, so traditional heat exchanger metal materials such as aluminum and copper are easily corroded and damaged heat transfer device
