Description

technical field [0001] The invention belongs to the technical field of waste heat recovery and utilization, and in particular relates to a solution regeneration device based on the utilization of low-temperature flue gas waste heat in a regenerator. Background technique [0002] In recent years, the solution dehumidification technology has been developed rapidly. The solution dehumidification system can be driven by a low-temperature heat source. It uses a salt solution with strong moisture absorption capacity to exchange heat and mass with humid air in a dehumidifier, thereby achieving the purpose of air dehumidification. , which overcomes the problems of high-grade energy consumption, high energy consumption and environmental pollution in freezing dehumidification. The dehumidifier and regenerator are the most important components of the solution dehumidification air conditioning system. The regenerator concentrates and regenerates the solution for continued use by the de...

Problems solved by technology

However, the existing solution dehumidification technology often uses hot water generated by solar collectors as a regeneration heat source, and uses hot water to heat the solution through a partition heat exchanger to regenerate it. However, solar energy is discontinuous throughout the day, so it does not Suitable for continuous running processes in industry

Moreover, the hot water and the solution generated by the solar collector conduct heat transfer indirectly through the partition wall. There are many factors affecting the heat transfer, the heat transfer effect is not ideal, and the low-temperature flue gas waste heat of the industrial furnace cannot be recycled.

Moreover, even if the partition wall heat exchanger is used to recover the waste heat of the flue gas to heat the solution, the flue gas contains SO 2 , NO x and other gases that are likely to corrode the heat exchanger and shorten the service life
