Description
Technical Field
The utility model relates to a heat exchanger field especially relates to bearing structure of bow-shaped heat exchange tube.
Background
The heat exchange tube of the existing large-scale heat exchanger is an arched heat exchange tube, namely as shown in fig. 1, two ends of the heat exchange tube are straight sections, the middle of the heat exchange tube is also a straight section, the straight sections at the two ends are connected with the straight section at the middle through inclined sections, the joint of the inclined sections and the straight sections is provided with a radius corner with a radius of R, the angle between the inclined sections and the straight sections is theta, the offset distance of the straight section at the middle relative to the straight sections at the two ends is D, wherein the theta value and the D value of each heat exchange tube are different, and the heat exchange tubes of the whole group of tube bundles are of a gradual change type.
The heat exchanger with the arched heat exchange tubes cannot finish the manufacture of tube bundles like the traditional heat exchanger, and can not adopt the method of pre-assembling baffle plates and supporting plates and then performing tube penetration. In order to ensure that the catalyst falls to the bottom from the top of the equipment to the maximum extent, the structure of the tube bundle supporting device is a round steel pull rod type support, namely, a row of transverse pull rods are firstly penetrated, then a row of heat exchange tubes are arranged, the heat exchange tubes in the row are fixed and welded after being arranged in place, a row of longitudinal pull rods A and B are penetrated after the positions and the orientations of the heat exchange tubes are fixed and aligned, and the longitudinal pull rods are mutually welded and fixed with the transverse pull rods and are welded and fixed with the L-shaped inner ring and the L-shaped outer ring (as shown in figure 2 and figure 3). And the lower row of sleeves are welded with the upper row of supporting clamps and clamped on the upper row of transverse pull rods relative to the sleeves outside the heat exchange tubes. The tube bundle generally comprises 8-10 groups of L-shaped inner and outer rings, and each group of L-shaped inner and outer rings are connected and fixed by a length-direction pull rod, as shown in figure 4.
By adopting the mode, the structure of the tube bundle supporting device is complex, the assembly difficulty is high, and at least three defects are as follows:
(1) the heat exchange tube is difficult to position and align after passing through the tube: after the arched heat exchange tubes penetrate through the tube plates at the two ends, although the positioning of the heat exchange tubes at the positions of the tube plates at the two ends can be ensured, because the arched heat exchange tubes can rotate circumferentially in the tube bundle, the round steel pull rod type support is adopted, a row of transverse pull rods penetrate through the arched heat exchange tubes, when a row of heat exchange tubes are arranged, a longitudinal pull rod and a sleeve are required to be arranged according to the structure shown in the figure 3, the arched heat exchange tubes can be ensured to be fixed after the sleeve and the pull rods are welded; when the heat exchange pipe is not fixedly provided with the sleeve, the arched heat exchange pipe can rotate, so that the assembly difficulty of the pipe bundle is high;
(2) the bundle pull rod type support is anti-deformation poor: in order to ensure that the catalyst falls to the bottom from the top of the equipment to the maximum extent, the tube bundle pull rod type supporting device only adopts pull rods with the diameter of 10mm to form a horizontal pull rod area and a longitudinal pull rod area to form a support (as shown in figure 3), but the product performance cannot be ensured because the rigidity of the pull rods with the diameter of 10mm is too poor; the weight of the tube bundle after penetrating the tube is about 100 tons, when the equipment is in a horizontal state during manufacturing, due to the weight of the tube bundle, the pull rod is easy to collapse under pressure, and the support rigidity of the whole tube bundle is poor;
in order to ensure that the support does not deform, a process support is often adopted for deformation prevention, namely, a circumferential support tool is additionally arranged outside the whole tube bundle to prevent deformation; however, the process support needs to be removed before the shell and the tube bundle are sleeved, so that the subsequent tube bundle can collapse and deform due to insufficient support structure;
(3) the bundle pull rod type support has directionality to the support of the heat exchange pipe: the support of the tube bundle pull rod type support to the heat exchange tube is influenced because the direction of the heat exchange tube rotates; specifically, the pull rod type support is mainly supported by the transverse pull rod and positioned by the longitudinal pull rod, so that the transverse pull rod can not support the heat exchange tube any more once the heat exchange tube rotates in the manufacturing and transporting processes, and the heat exchange tube can drop due to self weight, so that the tube bundle is deformed, as shown in fig. 5.
