Embodiment Construction
[0020] The present invention is described in further detail now in conjunction with accompanying drawing. These drawings are all simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, so they only show the configurations related to the present invention.
[0021] Such as figure 2 , image 3 and Figure 4 Shown is the best embodiment of the flue gas evaporator which is easy to repair in the present invention, which includes a shell, a tube box and a U-shaped tube bundle. The shell includes an equipment flange 1, which is arranged at the end of the shell, and the tube box Including pipe box flange 6, pipe box flange 6 is set at the end of pipe box, pipe box flange 6 and equipment flange 1 are connected by bolts; U-shaped tube bundle includes tube plate 14 and U-shaped tube group 15, tube plate 14 Located between the pipe box flange 6 and the equipment flange 1, the U-shaped tube group 15 is vertically inserted...

The invention relates to a flue gas evaporator easy to overhaul. The flue gas evaporator easy to overhaul comprises a shell, a tube box and a U-type tube bundle. The shell comprises an equipment flange disposed at the end of the shell, the tube box comprises a tube box flange disposed at the end of the tube box, and the tube box flange is connected with the equipment flange through a bolt. The U-type tube bundle comprises a tube plate and a U-type tube stack, the tube plate is disposed between the tube box flange and the equipment flange, the U-type tube stack is perpendicularly inserted into the tube plate to be communicated with the tube box, and the tubes of the tube stack are horizontally parallel to each other inside the shell. The flue gas evaporator easy to overhaul has the effect of releasing thermal stress of a heat exchange tube by means of axial elastic deformation of the heat exchange tube, and has the advantage that workers can conveniently replace and clean the tube bundle and overhaul and clean the equipment due to the fact that the bolted flange structure is detachable.
Description
technical field [0001] The invention relates to a flue gas evaporator, in particular to a flue gas evaporator which is easy to repair. Background technique [0002] Existing flue gas evaporators (such as figure 1 As shown) there are tube plates at both ends to fix the heat exchange tubes, and the tubes will be stretched and damaged when the main engine vibrates. Moreover, when heated and expanded, due to the large temperature difference between the tube side and the shell side, the pressure components of the tube side and the shell side will generate a large temperature difference stress under the temperature difference, and the expansion and contraction of the shell side cylinder If it is small, the deformation of the cylinder cannot adapt to the expansion and contraction of the heat exchange tube. When it is severe, the joints between the tube sheet and the heat exchange tube will be completely destroyed, and the weld between the cylinder and the tube sheet will crack, re...
