Problems solved by technology

However, the flue gas contains a lot of acid gases such as sulfur dioxide. The acid gas dissolves in water to form acid droplets, which will corrode the equipment and reduce the service life of the equipment.
The particle condensation heat exchanger can remove the acidic mist in the flue gas, but the acidic mist is adsorbed on the serpentine tube and fins and then drips down and splashes easily, causing secondary entrainment, which not only reduces the particle condensation heat exchanger The filtering effect of the heater will also reduce the service life of the surrounding equipment

Description

technical field [0001] The invention relates to an intelligent heat exchanger, which belongs to the field of heat exchangers. Background technique [0002] A heat exchanger is a device that transfers part of the heat of a hot fluid to a cold fluid, also known as a heat exchanger. Heat exchangers play an important role in chemical, petroleum, power, food and many other industrial productions. In chemical production, heat exchangers can be used as heaters, coolers, condensers, evaporators and reboilers, etc., and are widely used . The traditional fixed tube-sheet heat exchanger has a large volume, a small heat transfer area, and low heat transfer efficiency, making it inconvenient to use. There are many types of heat exchangers, including particle condensation heat exchangers according to their uses. The particle condensation heat exchangers are used to absorb the heat in the fluid, so that the water vapor in the airflow is exothermic and condensed into mist droplets and ads...
