Description

Technical Field

[0001] This utility model relates to the field of Teflon heat exchange technology for waste gas, specifically to a Teflon heat exchange device for waste gas. Background Technology

[0002] Teflon thermal exhaust gas refers to the gas released when Teflon (PTFE) materials decompose at high temperatures. Teflon, also known as polytetrafluoroethylene (PTFE), decomposes at high temperatures and releases harmful gases, mainly including hydrogen fluoride (HF) and other organic gases. Due to the heat generated, heat exchange devices are usually used to recover and reuse the heat energy to avoid waste.

[0003] Existing heat exchange devices involve complex and costly manufacturing processes, and the lining process is not conducive to operations such as vacuuming, which can easily lead to lining peeling.

[0004] To address the aforementioned technical issues, CN218973309U discloses a novel corrosion-resistant heat exchanger that uses a PPS plastic coating to spray the end caps to improve the corrosion resistance and wear resistance of the metal surface, extend the equipment's lifespan, and avoid the use of expensive stainless steel or titanium and other special steels.

[0005] The existing technology still has the following shortcomings: In actual use, because the pipeline for transporting Teflon hot exhaust gas is a special pipeline, multiple sets of pipelines are set up to ensure heat exchange effect and efficiency. Therefore, it is not convenient to fix and organize the pipeline for heat exchange, and it is necessary to carry out the operation step by step by means of adhesive or direct binding.

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0036] This utility model provides a Teflon heat exchange device for hot waste gas, including a housing 1;

[0037] A heat exchange mechanism 3 and a locking mechanism 4 adapted to and fixed to the heat exchange mechanism 3 are installed inside the housing 1 for heat exchange.

[0038] Heat exchange mechanism 3 includes;

[0039] A delivery pipe 35 for gas delivery during heat exchange is installed inside the housing 1, and a connecting assembly for supporting the delivery pipe 35 is provided on the outside of the connecting assembly for connecting to the housing 1.

[0040] Locking mechanism 4 includes;

[0041] A first limiting plate 41 is disposed on the outside of the conveying pipe 35 and performs a limiting function. The surface of the first limiting plate 41 is provided with a fixing component for locking the conveying pipe 35 and a locking component adapted to the conveying pipe 35.

[0042] Preferred;

[0043] like Figure 4 As shown, the connecting components include;

[0044] A connecting pipe 33 is installed outside the conveying pipe 35, and an outer pipe 34 is connected to the connecting pipe 33. The outer pipe 34 and the connecting pipe 33 are connected by a flange.

[0045] The connecting pipe 33 is used to limit and fix the inlet and outlet ports of the conveying pipe 35, and at the same time, it works with the connecting pipe 33 to realize the inlet and outlet operation of several sets of connecting pipes 33.

[0046] further;

[0047] like Figure 4 As shown, the installation components include;

[0048] A top plate 31 is fixed to the outside of the connecting pipe 33 for fixing the connecting pipe 33, and a frame 32 for supporting the locking mechanism 4 is fixedly installed at the bottom of the top plate 31.

[0049] The top plate 31 facilitates the connection and support of the frame 32, and is fixed to the top of the box 1 by bolting to achieve a sealed operation.

[0050] Going a step further;

[0051] like Figure 4 As shown, the fixing components include;

[0052] A second limiting plate 44 is disposed on the surface of the first limiting plate 41 to adapt to the first limiting plate 41 in limiting the conveying pipe 35. A second sliding strip 43 is installed at the outer end of the second limiting plate 44 to adapt to the locking assembly.

[0053] After the second limiting plate 44 and the first limiting plate 41 are adapted to each other, the conveying pipe 35 between them is clamped and limited. The second slide bar 43 is used to slide and adapt to the second slide groove 42 and is tightened by the bolt 45 after adaptation.

[0054] in;

[0055] like Figure 4 As shown, the locking assembly includes;

[0056] A second slide groove 42 is provided on the inner side wall of the frame 32 to accommodate the sliding of the second slide bar 43, and a bolt 45 is provided to abut against the second slide bar 43. The bolt 45 is threadedly connected to the frame 32 through a threaded hole.

[0057] This facilitates the adaptation to the second slide bar 43 mentioned above and the completion of the clamping and limiting operation through thread extension.

[0058] also;

[0059] like Figure 3 As shown, the inner wall of the housing 1 is provided with a vertical insertion mechanism 2 for auxiliary heat exchange, the vertical insertion mechanism 2 includes;

[0060] A sliding assembly and an insertion assembly adapted to the sliding assembly are installed on the inner side wall of the housing 1.

[0061] The inner wall of the box 1 is also fixed with a carrier plate 21 for supporting the top plate 31.

[0062] The carrier plate 21 is used to support the top plate 31, ensuring that it is in the preset position after being placed inside the box 1.

[0063] at last;

[0064] like Figure 3 As shown, the insertion component includes;

[0065] A connecting plate 22 fixed to the inner side wall of the housing 1 and a first sliding groove 23 adapted to the insertion assembly;

[0066] A first slide bar 24 and a copper wire group 25 connected to the first slide bar 24 are slidably connected inside the first slide groove 23.

[0067] The sliding fit between the first slide groove 23 and the first slide bar 24 facilitates the placement and removal of the copper wire assembly 25. Several sets of copper wires are installed on the copper wire assembly 25. As a result, the copper wires have high heat absorption capacity during heat exchange, thereby achieving heat transfer to the surrounding gas or liquid, thus improving the uniformity and effect of heat exchange.

[0068] During installation, the following components need to be installed before installation. First, take out the copper wire assembly 25 and drive the first slide bar 24 to insert it into the first slide bar 24 to complete the installation. Conversely, pull it upward to take it out. The distributed copper wire assembly 25 can evenly distribute heat based on its good heat transfer properties.

[0069] In use, install and connect the connecting pipe 33 and the outer pipe 34 at both ends of several sets of conveying pipes 35. Then, bend them according to the bending method shown in the figure and place them in the arc groove on the surface of the first limiting plate 41. Then, take out the second limiting plate 44 and drive the second slide bar 43 to be inserted into the inside of the second slide groove 42 until the first limiting plate 41 and the second limiting plate 44 are tightly fitted. At this time, the conveying pipe 35 located between the first limiting plate 41 and the second limiting plate 44 is clamped and limited. Then, tighten the bolt 45 to lock the second slide bar 43. The outer side of the second slide bar 43 can also be opened with an internal thread blind hole that matches the bolt 45, which can increase the connection effect when fixing. When disassembling, simply reverse the above operation.

[0070] Then, take the top plate 31 and move it together with the frame 32 and the above-mentioned connected components until it is inserted into the inside of the box 1 from top to bottom. The carrier plate 21 supports and limits the top plate 31 when it is inserted vertically. Then, it is fixed to the top of the box 1 by bolting. At this time, the top of one side of the box 1 is connected to the inlet pipe and the bottom of the other side of the box 1 is connected to the outlet pipe, so that the inlet and outlet work can be realized when gas-liquid heat exchange is performed. When taking it out, the operation is reversed in the above manner.

[0071] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
