[0002] Shell and tube condensers are condensing equipment often used in chemical production. Currently, this type of equipment uses smooth tubes or threaded tubes (or low-fin tubes). Among them, threaded tube condensers have higher condensation efficiency than smooth tube condensers. Threaded tubes are so-called low-fin tubes. Low-fin tubes are smooth tubes with a thread-like structure rolled on the outer wall to increase the condensation area and condensation efficiency.

[0003] The finning of low-fin tubes is relatively low. Corresponding to low-fin tubes are high-fin tubes. The fins outside high-fin tubes are generally spiral metal fins added to the outside of the plain tubes, which can greatly increase the finning area and improve the finning ratio.

[0004] However, existing high-fin tubes are mostly fixed by welding inside the equipment, which is prone to torsion deformation and fracture due to high stress, resulting in low stability of the condenser tubes, low equipment operation safety and service life. Utility Model Content

A pull rod 4 is connected, the pull rod 4 passes through the support plate 6 and is fixedly connected to the support plate 6 through a fastening nut 3; the fastening nut 3 can be adjusted to adjust the tension and the distance between the support plates 6; a support tube 61 is fixedly connected to the support plate 6, the condenser tube passes through the support tube 61, and the end is connected to the tube plate 2; the support tube 61 can provide stable support for the high-fin tube 9, thereby solving the support problem of the high-fin tube 9 inside the equipment, so as to increase the stability of the condenser tube and improve the equipment operation safety and service life.

[0025] Furthermore, the support plates 6 are arranged in parallel at equal intervals, and the condenser tubes can be supported by multiple support tubes 61, so as to improve the stability; at the same time, each support plate 6 is connected with multiple condenser tubes, and the multiple condenser tubes together form a tube bundle to improve the condensation area and condensation effect; and the support tubes 61 are symmetrically arranged with respect to the support plate 6, so that the torques on both sides are balanced with each other, so as to improve the stability of the support tube 61.

[0026] Furthermore, two supports 8 are welded at intervals on the bottom side of the shell 7 to provide stable support for the condenser body.
