This utility model relates to the field of condenser technology, and in particular to a
distillation condenser, including a shell-and-tube condenser used for gas-phase condensation in a
distillation column
system. The shell-and-tube condenser includes: a main
assembly, including a left tube sheet fixed to the left end of the shell, a tube box fixed to the left end of the left tube sheet, and inlet and outlet ports fixed to both the upper and lower ends of the tube box, with
flange heads fixed to the outer ends of the inlet and outlet ports; and a connecting
assembly, including four circumferentially arranged lugs fixed to the outer edge of the bottom of the
flange head, with clamping arms pivotally connected to the outer ends of the lugs, and clamps installed at the bottom of the upper ends of the clamping arms. External threaded sleeves are rotatably fitted on the outer walls of the inlet and outlet ports, and internal threaded rings are threadedly fitted on the outer walls of the external threaded sleeves. Four circumferentially arranged connecting rods are pivotally connected to the outer walls of the internal threaded rings. This simplifies the tedious operation of tightening multiple bolts one by one in traditional
flange connections to a single
rotation action, achieving rapid, synchronous, and uniform tightening of the flange, improving the efficiency of pipeline connection operations, and shortening equipment maintenance time.
