What Is a Reboiler?

Reboilers (also known as reboilers), as the name suggests, vaporize the liquid again. Its structure is similar to that of a condenser, but one is used to cool down, while a reboiler is used to heat up and vaporize.

Scaling:

Reboilers are widely used in chemical plants. Reboilers (also known as reboilers) can vaporize liquids again. They are a special heat exchanger that can exchange heat and vaporize liquids at the same time; they are mostly used with fractionation towers; The material expands or even vaporizes when heated in the reboiler, and the density becomes smaller, so it leaves the vaporization space and returns to the tower smoothly. After long-term use, material scale is formed in the heat exchange tube. When the scale layer is getting thicker, the production efficiency is reduced, and even the production shutdown accident is caused. The descaler of the reboiler can be cleaned with a cleaning agent.

corrosion:

In the production process, due to the erosion of the tube sheet of the heat exchanger, cavitation and corrosion of trace chemical media, leakage often occurs at the tube sheet welds, resulting in the mixing of water and chemical materials, and the difficulty in controlling the production process temperature, resulting in the generation of Other products seriously affect product quality and reduce product grade. After the weld of the condenser tube sheet leaks, the company usually repairs it with traditional repair welding methods. The internal stress of the tube sheet is prone to be generated and it is difficult to eliminate it, which causes leakage in other heat exchangers. The company checks the repair status of the equipment by pressing After repeated repair welding and experiments, 2 to 4 people need several days to complete the repair. After a few months of use, the tube sheet welds again corrode, causing waste of human, material and financial resources and increasing production costs.
