Elliptic tube deflection bar type condenser

The utility model provides an elliptic tube deflection bar type condenser used on petrochemical engineering equipment. The utility model comprises a casing, a fixed tube plate, a floating tube plate, a condensation tube, a deflection ring and a sliding bar, wherein the condensation tube which is arranged in the casing is fixed between the fixed tube plate and the floating tube plate and is penetrated through the multiple deflection ring. The outer circumferential edge of the deflection ring is fixed by the sliding bar. The condensation tube adopts an elliptic tube. A long shaft of the elliptic tube is positioned in the vertical direction, and a short shaft is positioned in the horizontal direction. Under the same conditions, the heat transferring circumference of the elliptic tube is more than that of a circular tube, therefore the heat resistance in the tube is small, which is good for medium in the tube to transfer heat. The heat transferring area of the elliptic tube is 15% more than that of the circular tube having the same cross sectional area. Under the same flow velocity, the heat exchanging rate outside the tube can be improved by 15%. Compared with the circular tube, the outer average condensation heat exchanging factor of the elliptic tube is improved by 10%-18%. Compared with a circular tube deflection bar type condenser group, the condensation effect can be improved by 20%-30% by the elliptic tube deflection bar type condenser. The manufacturing cost of the elliptic tube is low. The utility model is easily popularized in chemical equipment.
