A pumpless solution dehumidification regeneration device based on solution immersion

Abstract

The invention discloses a pumpless solution dehumidification regeneration device based on solution immersion, comprising a pumpless solution dehumidification regeneration device based on solution immersion, including a liquid storage tank and a medium for removing gas arranged inside the liquid storage tank The dehumidification unit of moisture; the dehumidification unit includes several dehumidification disks and the rotating shaft (22) passing through the center of the dehumidification disk; the two ends of the rotation shaft pass through the liquid storage tank and are fixed on the side wall of the liquid storage tank; A wetting layer for wetting the dehumidification solution and a fixing layer for fixing the wetting layer on the surface of the wetting layer. The device of the present invention distributes the dehumidification solution by using the wetting effect of the wetting material, and realizes the renewal of the solution on the heat and mass transfer surface through the rotation of the dehumidification disc and the small-scale flow of the solution on the wetting material, which significantly reduces the pressure on the treated air. It solves the problem of liquid entrainment, and at the same time improves the stability of the wet surface. It has excellent application prospects in the case of shaking and vibration in the installation position of the equipment.

Description

technical field [0001] The invention relates to a dehumidification device, in particular to a pumpless solution dehumidification regeneration device based on solution immersion. Background technique [0002] Solution dehumidification and drying is an efficient gas humidity adjustment method. In the dehumidifier, the solution with low water vapor partial pressure is contacted with the gas to be dehumidified, and the water in the gas is driven to transfer to the solution by using the water vapor partial pressure difference to achieve the purpose of reducing the moisture content of the gas; in the regenerator, The solution with high water vapor partial pressure is contacted with the regeneration gas to drive the water in the solution to transfer to the gas to achieve the purpose of increasing the concentration of the solution. This technology can achieve gas dehumidification driven by low-grade heat energy, and has the characteristics of efficient use of waste heat energy. At ...

Problems solved by technology

Although this method has fully utilized the surface area of ​​the material, due to the large solution flow rate, the following problems will occur: (1) the power consumption of the solution circulation pump is large, which reduces the economical efficiency of the device operation; (2) the solution flow rate is too fast, resulting in The solution film on the surface of fillers, falling film plates and other materials is easily broken and mixed into the gas, forming liquid foam carry, which affects the quality of the outlet gas; (3) If the dehumidification solution is corrosive, due to the above liquid foam carry problem, it will damage the air near the gas outlet Equipment produces corrosion

However, the reduction of solution circulation in this method will lead to a slowdown of solution renewal rate, resulting in excessive temperature rise during solution dehumidification or temperature drop during solution regeneration, which may lead to insufficient mass transfer driving force on the gas-liquid contact surface. , affecting the further improvement of dehumidification / regeneration efficiency
