Why is this called a demister?

Isn’t this just a graphite heat exchanger? It just eliminates the cooling water.
The main purpose of the graphite cooler is cooling, but the graphite block is permeable, so it not only cannot remove acid mist but also introduces moisture. The purpose of the defoaming filter is to remove friction from acid mist. It is generally used in conjunction with a graphite cooler.
Graphite heat exchangers are used for cooling, heating, and absorption. The one in the picture above belongs to the tower category and belongs to pure graphite. There are graphite bubble towers, desorption towers, distillation towers, washing towers, etc., which are mainly used for rectification, desorption, distillation, synthesis, etc. You are talking about the top of the defoaming tower. It is equipped with a defoaming device with graphite packing to solve the problem of serious acid mist at the top of the tower caused by too fast gas speed during operation. It is recommended to test the pressure of these towers before use. The appearance is severely rusted. It is recommended to replace the fasteners to reduce the incidence of accidents.
