Detailed Description
The following describes embodiments of the present invention with reference to the drawings.
A U-tube reboiler shown in fig. 1 to 4, comprising a tube sheet 1, wherein the tube sheet 1 is provided with a plurality of installation through holes, and two ends of a U-tube 7 are respectively inserted into the installation through holes to form a tube bundle; one side of the tube plate 1 is connected with eight pull rods 2 through screws, and the pull rods 2 are uniformly arranged along the circumferential direction of a central shaft of the tube plate 1 and are vertical to the tube plate 1; one end of the baffle plate 3 is missing a circular arc-shaped plate, and the plate surface of the baffle plate 3 is provided with a plurality of baffle holes 301 for the U-shaped pipes 7 to pass through and six pull rod through holes 302 for the pull rods 2 to pass through; the baffle plate 3 comprises an upper baffle plate 304 and a lower baffle plate 305, one end of the upper baffle plate 304 lacking the arc-shaped plate vertically extends downwards into the tube bundle and has a gap with the pull rod 2 at the lower end, and the other end is higher than the pull rod 2 at the upper end; one end of the missing arc-shaped plate of the lower baffle plate 305 vertically extends upwards into the tube bundle and has a gap with the pull rod 2 at the upper end, and the other end is higher than the pull rod 2 at the lower end; two guide holes 303 for inserting the guide plates 4 are symmetrically formed in the arc periphery of the lower baffle plate 305, the included angle between the axes of the two guide holes 303 is 30 degrees, and the guide plates 4 are inserted into the guide holes 303 and fixedly connected with the baffle plate 3.
