Abstract
Description
Technical Field
[0001] This utility model relates to the field of heat exchanger technology, specifically a spiral baffle heat exchanger. Background Technology
[0002] Baffles are crucial components for improving heat exchanger efficiency. Spiral baffle heat exchangers utilize idealized spiral baffles, resulting in a continuous spiral baffle heat exchanger without a central tube, unlike discontinuous spiral baffle heat exchangers on the market. Spiral baffle heat exchangers offer advantages such as improved heat transfer efficiency, reduced shell-side resistance, improved vibration control, and reduced fouling.
[0003] For example, utility model application number 202420499679.2 discloses a spiral baffle heat exchanger. This utility model extends the edge of the baffle by setting baffles and anti-short-circuit baffles, so that short circuits are not formed between adjacent baffles. This ensures that when the gas flows, it will move spirally along the baffles, thereby ensuring the heat exchange effect between the gas and the liquid, ensuring the local heat exchange effect, preventing uneven heat exchange, and ensuring the overall heat exchange effect. However, the spiral baffles inside the existing spiral baffle heat exchangers are usually a whole. When a single part is damaged, the entire spiral baffle needs to be replaced, which increases the cost.
[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a spiral baffle heat exchanger. Utility Model Content

[0007] Furthermore, an end plate is installed at the end of the housing, and an end hole is formed on the surface of the end plate.
[0008] Furthermore, an assembly flange is installed on the side of the end plate, and a head is installed on the side of the assembly flange.
[0009] Furthermore, an end tube is installed on the side of the end cap, and two sets of end caps and end tubes are symmetrically arranged about the vertical central axis of the shell.
[0010] Furthermore, the water inlet pipe has an installation groove inside, and the installation groove is equipped with an anti-clogging component for filtering and preventing clogging.
[0011] Furthermore, the anti-clogging component includes a mounting ring and a threaded layer, and the threaded layer is installed on the outer side of the mounting ring.
[0012] Furthermore, the anti-clogging component also includes a control groove and a filter bucket. The control groove is provided on the side of the mounting ring, and the filter bucket is installed on the side of the mounting ring.
[0013] Furthermore, the mounting ring is threadedly connected to the water inlet pipe via a threaded layer, and the mounting ring and the filter bucket are fixedly connected.
[0014] This utility model provides a spiral baffle heat exchanger, which has the following beneficial effects:
[0015] 1. This utility model consists of three sets of spiral baffle plates forming a complete spiral baffle. If a single part of the spiral baffle is damaged, the damaged part of the plate can be replaced, reducing costs and maintenance difficulty. The mounting holes are used for the installation and positioning of heat exchange tubes, making heat exchange more convenient.

[0021] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model. Example
[0022] like Figure 1 and Figure 2 As shown, a spiral baffle heat exchanger includes a shell 1 and a heat exchange assembly 4. An inlet pipe 2 is installed on the right side of the lower end of the shell 1, and an outlet pipe 3 is installed on the left side of the upper end of the shell 1. The heat exchange assembly 4, which is designed for easy assembly and replacement, is located inside the shell 1. The heat exchange assembly 4 includes spiral baffle plates 401, mounting holes 402, assembly holes 403, and assembly rods 404. Mounting holes 402 are formed on the surface of the spiral baffle plates 401. Three sets of spiral baffle plates 401 form a complete spiral baffle. If a single section of the spiral baffle is damaged, the damaged section can be replaced, reducing costs and maintenance difficulty. The mounting holes 402 are used for the installation and positioning of the heat exchange tubes 5, making heat exchange more convenient. The baffle plate 401 has an assembly hole 403 on its side. An assembly rod 404 is installed inside the assembly hole 403. The assembly hole 403 and the assembly rod 404 are engaged and fixed with bolts, making the installation simple and secure. A heat exchange tube 5 is installed inside the mounting hole 402. An end plate 6 is installed at the end of the shell 1. The end plate 6 is used to install the heat exchange tube 5 inside the shell 1. An end hole 7 is opened on the surface of the end plate 6. An assembly flange 8 is installed on the side of the end plate 6. An end cap 9 is installed on the side of the assembly flange 8. The end cap 9 is connected to the pipeline through the end pipe 10 for the liquid to flow into the heat exchange tube 5 to complete the heat exchange. An end pipe 10 is installed on the side of the end cap 9. Two sets of end caps 9 and end pipes 10 are symmetrically arranged about the vertical central axis of the shell 1. Example
[0023] like Figure 3As shown, the inlet pipe 2 has an internal mounting groove 11 for installing the anti-clogging component 12. The anti-clogging component 12, which includes a mounting ring 1201 and a threaded layer 1202, is installed on the outer side of the mounting ring 1201. The mounting ring 1201 is threadedly connected to the mounting groove 11 via the threaded layer 1202. The filter bucket 1204 is then installed into the inlet pipe 2, making installation and removal convenient and preventing clogging. The blocking assembly 12 also includes a control groove 1203 and a filter bucket 1204. The control groove 1203 is provided on the side of the mounting ring 1201, and the filter bucket 1204 is installed on the side of the mounting ring 1201. The mounting ring 1201 is threadedly connected to the water inlet pipe 2 through the threaded layer 1202, and the mounting ring 1201 and the filter bucket 1204 are fixedly connected. The filter bucket 1204 plays a role in filtering the liquid, reducing the accumulation of dirt inside the housing 1 and on the surface of the spiral baffle plate 401.
[0024] In summary, this spiral baffle heat exchanger is first based on Figures 1-3 The structure shown in the diagram connects the mounting ring 1201 to the mounting groove 11 via the threaded layer 1202. The filter bucket 1204 is then installed into the inlet pipe 2, making assembly and disassembly simple.
