Abstract： |
The invention relates to a liquid distribution type casing pipe condenser, belonging to the heat equipment technology field, which comprises a cooling water inlet (1), a first stage header (2), a condenser steam inlet (3), a last stage header (5), a cooling water outlet (6) and an internal pipe (12), wherein the two ends of the internal pipe (12) are connected with a water (steam) collecting head (4), the condenser steam inlet (3) is connected with the first stage header (2) and connected with a second stage header (9) through a first group heat exchange casing pipe (11) and the water (steam) collecting head (4) of the two ends of the first group heat exchange casing pipe, the second stage header (9) is communicated with a next stage header through the other group heat exchange casing pipe (11) and the water (steam) collecting head (4) of the two ends of the other group heat exchange casing pipe; ellipsis; until the last stage header (5). The invention effectively reduces the liquid film thickness and the adverse two-phase flow pattern in the condensation process, increases the heat exchange effect of film condensation, improves the condensation heat exchange coefficients in the pipe and the performance, saves materials, simplifies processing, and reduces the manufacturing and operating cost of the condenser. |
