Technical Field

[0001] The utility model relates to the technical field of spray type heat exchangers, in particular to a spray type heat exchanger. Background Art

[0002] The spray heat exchanger is a commonly used heat exchange equipment used to transfer heat from liquid or gas. It injects the cooling medium into the heat source in the form of a spray, and uses the spray atomization method to increase the contact area, thereby achieving efficient heat exchange effect.

[0003] Although the existing spraying method can expand the spraying range by moving up and down, since most heat exchange tubes are cylindrical, water will flow along the outer circumference of the heat exchange tube during spraying, making it difficult to spray the bottom of the heat exchange tube, resulting in low heat exchange efficiency and a large amount of condensed water wasted.

[0012] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0013] The utility model proposes a spray type heat exchanger. The spray range of the spray type heat exchanger in the prior art is not large enough. The utility model uses a motor, a moving block, a screw A and a screw B. When the motor rotates, it drives a group of moving blocks to move from bottom to top along the direction of the screw A.

[0021] The utility model is further described below in conjunction with embodiments.

[0022] Embodiment 1:

[0023] See also Figure 1 , Figure 2 and Figure 3 The moving assembly 5 includes a motor 51 arranged on the upper surface of the shell 1, a screw rod A52 fixedly installed at the output end of the motor 51, and a moving block 53 threadedly connected to the outer surface of the screw rod A52. The interior of the moving block 53 is fixedly connected to one end of the pipeline 3. A box body 54 is arranged at the bottom of the moving block 53. A fan is arranged inside the box body 54. A grid plate 55 is arranged on one side of the box body 54. A connecting ring 56 is sleeved on the outer surface of the screw rod A52. Two groups of connecting rings 56 are arranged. The outer surfaces of the two groups of connecting rings 56 are sleeved with belts 57. A screw rod B58 is arranged inside one group of the connecting rings 56. The outer surface of the screw rod B58 is also threadedly connected to the moving block 53, the pipeline 3 and the box body 54. The thread directions of the outer surfaces of the screw rods A52 and the screw rod B58 are opposite. When the motor 51 rotates, it drives a group of moving blocks 53 to move from bottom to top along the direction of the screw rod A52. , and because the outer surface of the screw rod A52 is sleeved with a connecting ring 56, which is transmitted to another set of connecting rings 56 through a belt 57, the moving block 53 on the outer surface of the screw rod B58 moves in the opposite direction. And because the interior of the moving block 53 is provided with a pipe 3, the condensate can be sprayed out, so that the liquid can be sprayed not only from the bottom to the bottom of the heat exchange tube 2, but also to the upper surface of the heat exchange tube 2, so that the entire heat exchange surface can be well covered, so that the liquid and the gas or solid medium can be fully contacted and mixed, and the heat exchange surface can be effectively cleaned and flushed to prevent the formation of sediment and dirt, and has a good self-cleaning effect. And because a box body 54 is provided at the bottom of the moving block 53, the fan in the box body 54 can further improve the cooling effect of the condensed water, and can also help the atomized water droplets to float in the shell 1, thereby expanding the heat exchange range and improving the working efficiency.

[0024] An inclined plate 6 is provided at the bottom of the shell 1, a groove 61 is provided on the upper surface of the inclined plate 6, and a collecting cavity 62 is provided below the inclined plate 6. Excess condensed water flows along the groove 61 on the surface of the inclined plate 6 and gathers in the collecting cavity 62 for subsequent recovery and cleaning.

[0025] The spray assembly 4 includes an atomizing nozzle 41 arranged on the outer surface of the pipeline 3, a connecting pipe 42 arranged at one end of the pipeline 3, and a water pump 43 arranged at one end of the connecting pipe 42. A condensation water tank 44 is fixedly installed at one end of the water pump 43 through a pipeline. The condensation water in the condensation water tank 44 is pumped into the pipeline 3 by the water pump 43, and then sprayed out by the atomizing nozzle 41, thereby covering the outer surface of the heat exchange tube 2.

[0026] The installation direction of the atomizing nozzle 41 is toward the position of the heat exchange tube 2 , so that it is easier to spray to some blind corners of the heat exchange tube 2 .

[0027] A water pipe 7 is disposed at one end of the collection cavity 62 , a spray head 71 is disposed at one end of the water pipe 7 , and one end of the spray head 71 is fixedly mounted on the inner wall of the housing 1 to reuse the condensate in the collection cavity 62 .

[0028] A movable door 8 is hinged on the outer surface of the housing 1 to facilitate cleaning and maintenance of the interior of the housing 1 .

[0029] Specifically, when the motor 51 rotates, it drives a group of moving blocks 53 to move from bottom to top along the direction of the screw rod A52. Because the outer surface of the screw rod A52 is sleeved with a connecting ring 56, the transmission is transmitted to another group of connecting rings 56 through a belt 57, so that the moving block 53 on the outer surface of the screw rod B58 moves in the opposite direction. Because the inside of the moving block 53 is provided with a pipe 3, and because the outer surface of the pipe 3 is provided with an atomizing nozzle 41, the condensed water in the condensed water tank 44 is pumped into the pipe 3 through the water pump 43, and then sprayed out by the atomizing nozzle 41, so as to cover the outer surface of the heat exchange tube 2. Moreover, the atomizing nozzle 41 is tilted toward the direction of the heat exchange tube 2, which makes it easier to spray to some dead corners of the heat exchange tube 2. Therefore, the liquid can be sprayed not only from the bottom to the bottom of the heat exchange tube 2, but also to the upper surface of the heat exchange tube 2. Therefore, it can In order to better cover the entire heat exchange surface, so that the liquid and gas or solid medium can fully contact and mix, it can also effectively clean and flush the heat exchange surface to prevent the formation of sediment and dirt, and has a good self-cleaning effect. Because a box body 54 is provided at the bottom of the moving block 53, the fan in the box body 54 can further improve the cooling effect of the condensed water, and can also help the atomized water droplets to float in the shell 1, thereby expanding the heat exchange range and improving the working efficiency. Because an inclined plate 6 is provided at the bottom of the shell 1, the excess condensed water is gathered in the collection cavity 62 along the groove 61 on the surface of the inclined plate 6, and then through the water pipe 7 and the spray head 71, the condensate in the collection cavity 62 is reused. Finally, the movable door 8 hinged on the outer surface of the shell 1 can be opened to facilitate cleaning and maintenance of the inside of the shell 1.
