Hygroscopic solution regeneration system

Abstract

The invention discloses a hygroscopic solution regeneration system. The system comprises an evacuated collector pipe, a solution tank, a return pipe, an inlet valve, an outlet valve and an exhaust steam valve. During use, the exhaust steam valve and the inlet valve are switched on, and a hygroscopic solution enters the system from the inlet valve; the hygroscopic solution entering the evacuated collector pipe is heated by the evacuated collector pipe firstly, then due to the effect of the density difference between the hygroscopic solution in the evacuated collector pipe and the unheated hygroscopic solution exists, the hygroscopic solution flows in a closed loop formed by the evacuated collector pipe, the solution tank and the return pipe, and heating of the hygroscopic solution in the system is completed. Meanwhile, steam generated during heating of the hygroscopic solution is exhausted from the exhaust valve, regeneration of the hygroscopic solution is completed finally, and the regenerated hygroscopic solution flows out of the outlet valve to be recycled. By the design of the hygroscopic solution regeneration system, the hygroscopic solution is directly heated by the evacuated collector pipe, and the intermediate link of a heat exchanger is omitted, so that the heat transfer process is simplified, heat transfer efficiency is improved, and problems in the field at the present stage are solved.

Description

technical field [0001] The invention relates to the field of solar heat utilization, and more specifically relates to a hygroscopic solution regeneration system. Background technique [0002] Hygroscopic solution is dehumidification solution, which is widely used in modern industry, agriculture and daily life, such as lithium bromide solution, lithium chloride solution, etc. The hygroscopic solution reduces its own concentration while absorbing water, and obtains a dilute solution of the hygroscopic solution; however, in actual life and production, in order to recycle the hygroscopic solution, it needs to consume a certain amount of energy to evaporate the absorbed water , this process is the regeneration of the hygroscopic solution. [0003] The energy for moisture absorption solution regeneration is usually provided by fossil fuels, industrial waste heat, and solar energy. However, in the actual production process, considering factors such as economy, environmental protec...

Problems solved by technology

However, in the energy exchange process, the separate design of the solar heat collection system and the solution regeneration system has to increase the heat exchange link of the intermediate medium, which reduces the heat exchange efficiency and is not conducive to the full utilization of heat energy.
