Abstract
A system for coating a heat transfer tube for a condenser is disclosed. The system simplifies a process of coating the heat transfer tube, and is able to uniformly coat a plurality of heat transfer tubes. In addition, the system is economically feasible in that coating solution can be reused by collecting and circulating it. Due to super-hydrophobic coating, the size of a droplet condensed on the surfaces of the heat transfer tubes coated by the system can be reduced, and a condensation heat transfer coefficient can be increased.
Claims9
A system for coating a plurality of heat transfer tubes for a condenser, the system comprising:
- at least one pair of stationary rotating units configured to rotate a cylindrical bundle in which the plurality of heat transfer tubes are arranged;
- a pair of movable rotating units disposed below the cylindrical bundle to support the cylindrical bundle from a lower side of the cylindrical bundle;
- a spray unit facing a circumference of the cylindrical bundle and configured to spray a coating solution onto respective surfaces of the plurality of heat transfer tubes;
- a recovery unit disposed under the cylindrical bundle and configured to collect the coating solution remaining after the coating solution is sprayed onto the surfaces of the plurality of heat transfer tubes and flows downward over the surfaces of the plurality of heat transfer tubes;
- and
- a circulation unit communicating with the recovery unit and configured to supply the collected coating solution to the spray unit.
