Vertical condenser design
Thread Content
It is necessary to design a vertical condenser in which water flows through the tube side, while the gas phase serves as the medium on the shell side for condensation； The problem is that the liquid formed after gas condensation flows downward along the heat exchange tubes due to gravity, thereby affecting the heat exchange of the remaining gas. Is there any good way to address this issue? (When liquid droplets adhere to the external toothed surface of the heat exchange tubes, the heat exchange efficiency becomes very poor; however, given the limitations of available space, only vertical designs are possible.) The current solutions are: 1. Using expansion joints between the baffle plates and the heat exchange tubes, but this increases costs significantly and it is difficult to ensure consistency in the manufacturing process. 2. Reduce the size of the tube holes in the baffle plates and use plastic baffle plates; (this will increase the difficulty of inserting the tubes, and the effectiveness cannot be guaranteed.) Seeking advice. 、、 Does anyone have a better way to solve this?
It is better to choose a plate-type design, which allows for cross-flow of gas and liquid, resulting in a relatively high heat exchange efficiency
Without considering plate exchangers, only a vertical structure can be used; the boss has already made the decision. . .

Generally, for a condenser, it is reasonable to use circulating water in the shell side and gaseous fluid for condensation in the tube side, with liquid being discharged through the lower tube box. I’m not sure what requirements apply in our case
The gaseous condensing medium should enter from above and exit from below. The water should flow in from above and out from below.
You can choose a spiral plate heat exchanger
Increase the gas velocity in the shell side~~~Spiral baffle~~~~
Recalculate: what if we swap the media in the tube and shell sides?
Is it beneficial to install vertical heat exchangers at a certain angle in order to facilitate the detachment of liquid droplets? I haven’t used them before; please share your opinions
