Problems solved by technology

[0003] The heat exchangers currently on the market generally improve the working efficiency of the heat exchanger by increasing the transmission distance of the fluid in the heat exchanger and enlarging the contact area between the two fluids. Therefore, most of the heat exchanger shells are There are multiple material transmission pipelines, which greatly increase the residence time of materials in the heat exchanger shell, but d...

Embodiment 2: as shown in Figure 1 and 2, the side of sealed heat exchange zone 3 according to the present invention is provided with header 7, and described two helical pipelines 6 are connected by header 7 On the discharge port 9; through the header 7, the materials in the two spiral pipes 6 are concentrated to the discharge port 9 for discharge, which ensures the stable and uniform discharge effect of the heat exchanger and prevents the discharge due to the two spiral pipes. 6 Different positions lead to different heat transfer effects, which in turn lead to different discharge temperatures.

Embodiment 3: as shown in Figure 1 and 2, spiral pipeline 6 of the present invention is coiled on the inner wall of housing 1; The maximum transmission distance of the pipeline 6 in the shell 1, while there are no material transmission pipelines in other positions in the shell 1, ensures sufficient heat transfer space for the cooling or heating medium in the shell 1.

Embodiment 4: as shown in Figure 1 and 2, sealed heat exchange area 3 of the present invention is a sealed shell, and described liquid inlet 10 is arranged on the bottom of sealed heat exchange area 3, The top of the sealed heat exchange area 3 is provided with a transfer connectin...

Abstract

The invention discloses a multi-effect double-spiral folded plate heat exchanger. Four separation plates are arranged in a casing of the heat exchanger for separating the casing into three heat exchange regions including a sealed heat exchange region, a convection type heat exchange region and a spraying type heat exchange region, a material transmission system and a heat exchange system are arranged in the casing, the material transmission system consists of two spiral pipelines symmetrically arranged in the casing, and the heat exchange system consists of a medium transmission pipeline. The multi-effect double-spiral folded plate heat exchanger has the advantages that through two spiral pipelines wound on the inner wall of the casing, the transmission path of materials in the casing is maximized under the condition of not influencing the normal volume of heat transfer mediums in the casing, the three heat exchange regions in the casing are matched, the materials at different temperature ranges are respectively subjected to heat transfer in three different contact modes, and the temperature uniformity of material discharging and the temperature stability of materials at a material discharging opening are ensured.

Example Embodiment

[0017] Example 1: Such as figure 1 with 2 A multi-effect double spiral folded plate heat exchanger is shown, the heat exchanger is a cylindrical shell 1, and the shell 1 is provided with four partitions 2 to divide the shell 1 into three Two heat exchange areas: sealed heat exchange area 3, convection heat exchange area 4 and spray heat exchange area 5. The housing 1 is provided with a material transfer system and a heat exchange system. The material transfer system It is composed of two spiral pipes 6 symmetrically installed in the casing 1. The feed port 8 of the spiral pipe 6 is set in the spray heat exchange zone 5, and the discharge port 9 is set in the sealed heat exchange zone 3; The heat exchange system is composed of a medium transmission pipeline, the liquid inlet 10 of the medium transmission pipeline is arranged in the sealed heat exchange zone 3, and the liquid outlet 12 is arranged in the spray heat exchange zone 5.

Example Embodiment

[0018] Example 2: Such as figure 1 with 2 As shown, the side of the sealed heat exchange zone 3 of the present invention is provided with a header 7, and the two spiral pipes 6 are connected to the discharge port 9 through the header 7; through the header 7 The materials in the two spiral pipes 6 are concentrated to the discharge port 9 for discharge, which ensures the stable and uniform discharge effect of the heat exchanger and prevents the different heat transfer effects caused by the two spiral pipes 6 at different positions. This results in different discharge temperatures.

Example Embodiment

[0019] Example 3: Such as figure 1 with 2 As shown, the spiral pipeline 6 of the present invention is coiled on the inner wall of the housing 1; through the spiral pipeline 6 coiled on the inner wall of the housing 1, the maximum transmission of the spiral pipeline 6 in the housing 1 is ensured At the same time, there are no material transfer pipelines at other positions in the casing 1, which ensures sufficient heat transfer space for the cooling or heating medium in the casing 1.
