Technical field

[0001] The present invention relates to the field of chemical machinery, and in particular to a cooler. [Background Technology]

[0002] A cooler is a type of heat exchange device used to cool fluids. Water or air is typically used as the coolant to remove heat. They can be categorized as shell-and-tube coolers, plate coolers, and air-cooled coolers. Coolers are widely used in industries such as metallurgy, chemical engineering, energy, transportation, light industry, and food.

[0003] Please refer to Chinese Patent No. 201220453877.2, which discloses a vertical circulating air cooler. Figure 1 , Figure 1 The hemispherical head cooler is commonly used in the prior art. The disadvantages of this cooler are: the hemispherical head has a short stroke, a small space, shortens the residence time of the heat exchange medium in the head, and reduces the directionality of the heat exchange medium flow. Therefore, in order to solve this technical problem, the industry later developed a tapered tube box cooler. Please refer to the patent. Figure 2 , that is, a conical tube-box head is used to replace the hemispherical head in the existing technology. Although this conical tube-box head has a long stroke, a large space, and prolongs the residence time of the heat exchange medium in the head, it also has a structural defect: the heat exchange medium is easily accumulated on both sides of the wide mouth section of the conical tube-box head, thereby affecting the heat exchange efficiency.

The left tube sheet 2 is welded to the left end of the cylinder 1 and is provided with a plurality of first tube holes 20. The right tube sheet 4 is welded to the right end of the cylinder 1 and is provided with a plurality of second tube holes 40. The left tube box 3 and the left tube sheet 2 are connected by a plurality of first fixing members 21, and the right tube box 5 and the right tube sheet 4 are connected by a plurality of second fixing members 41. In this embodiment, the first fixing members 21 and the second fixing members 41 are bolts and nuts. The plurality of baffles 6 are evenly arranged along the longitudinal direction of the cylinder 1 within the cylinder 1, and the baffles 6 serve to support internal components such as the heat exchange tubes 7. The baffle 6 is provided with a plurality of third tube holes 60, and the heat exchange tube 7 is respectively passed through the first tube hole 20, the second tube hole 40 and the third tube hole 60, and the left end of the heat exchange tube 7 is welded to the first tube hole 20 of the left tube plate 2, and the right end of the heat exchange tube 7 is welded to the second tube hole 40 of the right tube plate 4. A spacing tube 9 is provided between each two adjacent baffles 6 and is sleeved on the pull rod 8. The function of the spacing tube 9 is to set the distance between the baffles 6.

[0022] The cylinder 1 is provided with a shell-side inlet 10 and a shell-side outlet 11. A water retaining device is provided near the shell-side inlet 10 in the cylinder 1. The water retaining device is composed of a plurality of anti-impact retaining rods 12. The anti-impact retaining rods 12 are provided in the baffle 6 and the left end of the anti-impact retaining rod 12 is threadedly connected to the left tube sheet 2. The function of the water retaining device is to prevent the fluid from entering from the shell-side inlet 10 from impacting the heat exchange tube 7 and other internal components. The bottom of the cylinder 1 is provided with a fixed saddle 13, a sliding saddle 14 and a plurality of condensate discharge ports 15.

[0023] The left pipe box 3 includes: a cone shell 30, a first flange 31, a short section 32, a second flange 33, a first inner plate 34, a second inner plate 35, a first sealing plate 36 and a second sealing plate 37. The cone shell 30 is arranged in a cone shape. The first flange 31 is welded to the wide end of the cone shell 30, the short section 32 is welded to the narrow end of the cone shell 30, the second flange 33 is welded to the short section 32, the first inner plate 34 and the second inner plate 35 are both welded to the inner side of the cone shell 30, the first sealing plate 36 is welded between the first flange 31 and the first inner plate 34, and the second sealing plate 37 is welded between the first flange 31 and the second inner plate 35, thereby dividing the space in the cone shell 30 into a first space 300 for accommodating a heat exchange medium, a second space 301 communicating with the outside, and a third space 302 communicating with the outside. The second space 301 is provided with a plurality of evenly arranged The first rib plate 3010 is provided with a first rib plate through hole 3011 on each first rib plate 3010, and a plurality of evenly arranged second rib plates 3020 are provided in the third space 302, and each second rib plate 3020 is provided with a second rib plate through hole 3021. The cone shell 30 is provided with a first cone shell through hole 303 which is connected with the second space 301 and a second cone shell through hole 304 which is connected with the third space 302. The setting of the first rib plate through hole 3011, the second rib plate through hole 3021, the first cone shell through hole 303 and the second cone shell through hole 304 can prevent the formation of a closed space in the second space 301 and the third space 302. The closed space is easy to expand when heated and thus causes damage to the structure. Therefore, the setting of the first rib plate through hole 3011, the second rib plate through hole 3021, the first cone shell through hole 303 and the second cone shell through hole 304 can avoid such damage.

[0024] The remaining structure of the right pipe box 5 is identical to that of the left pipe box 3 , differing in that the center of the first flange 31 in the left pipe box 3 is eccentrically positioned with the center of the second flange 33, while the center of the first flange 50 in the right pipe box 5 is concentrically positioned with the center of the second flange 51. These configurations can be customized based on specific operating conditions. The present invention improves the structures of the left and right pipe boxes 3 and 5 , allowing the corners, where heat exchange medium is likely to accumulate, to be directly separated by inner panels and sealing plates. This prevents heat exchange medium from accumulating in the corners of the pipe boxes, significantly improving heat exchange efficiency.

[0025] The working principle of the cooler in the present invention is as follows: the heat exchange medium enters the right tube box 5 from the tube side inlet 38 at the right end, the heat exchange medium in the right tube box 5 then enters each heat exchange tube 7, the shell side medium enters the shell side of the cylinder 1 from the shell side inlet 10 of the cylinder 1, and then the shell side medium exchanges heat with the heat exchange medium in the heat exchange tube 7, thereby cooling the shell side medium, and the cooled shell side medium then exits through the shell side outlet 11 on the cylinder 1, and the heat exchange medium in the heat exchange tube 7 enters the left tube box 3 after heat exchange, and finally exits through the tube side outlet 39 at the left end, and the cycle repeats.

[0026] In summary, the present invention improves the traditional pipe box structure by dividing the space inside the pipe box into a first space for accommodating the heat exchange medium, a second space communicating with the outside, and a third space communicating with the outside, so that the heat exchange medium enters the heat exchange tube only through the first space, thereby avoiding the technical problem of heat exchange medium accumulating in the second space and the third space in the prior art, thereby improving the heat exchange efficiency.

[0027] The above embodiments are merely illustrative of the principles and effects of the present invention, as well as some embodiments of its application, and are not intended to limit the present invention. It should be noted that a person skilled in the art can make several modifications and improvements without departing from the inventive concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
