Abstract
Description
Technical Field
[0001] This utility model pertains to non-standard automated exhaust gas filtration systems, and particularly relates to an exhaust gas filtration system for salt spray testing. Background Technology
[0002] Salt spray testers assess the salt spray corrosion resistance of materials and their protective layers, as well as compare the process quality of similar protective layers. They can also assess the salt spray corrosion resistance of certain products. This product is used for salt spray corrosion testing of protective layers for parts, electronic components, metal materials, and industrial products.
[0003] However, existing salt spray machines typically emit exhaust gases directly. After the exhaust gases drift away, they cause severe rust and corrosion to surrounding instruments, fixtures, and the environment, resulting in incalculable financial losses. Utility Model Content

Multiple filtration and demisting chambers are arranged longitudinally at intervals inside the second filter box, and adjacent filtration and demisting chambers are separated by mesh plates. The input pipe is connected to the bottom filtration and demisting chamber of the second filter box. The top of the second filter box is provided with a cover plate and is connected to the output pipe. A circulating water pump is provided inside the first filter box. The outlet of the circulating water pump is connected to the top of the filtration and demisting chambers through continuously bent water delivery pipes. Each filtration and demisting chamber is provided with a shower head below the water delivery pipe.
[0006] In a preferred embodiment of this utility model, handles are provided on both sides of the first filter box and the second filter box.
[0007] In a preferred embodiment of the present invention, the inner wall of the second filter box is supported by pads corresponding to the bottom edge of the mesh plate.
[0008] In a preferred embodiment of the present invention, the second filter box includes a first filtration and demisting chamber and a second filtration and demisting chamber arranged from top to bottom.
[0009] In a preferred embodiment of the present invention, both the first and second filtration and demisting chambers are filled with filter hollow spheres.
[0010] In a preferred embodiment of the present invention, multiple shower heads are provided on the water supply pipes at the top inner side of both the first and second filter demisting chambers.

Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0016] Please see Figure 1 As shown, the embodiments of this utility model include:
[0017] A salt spray test exhaust gas filtration system includes an input pipe 1, a filter box, and an output pipe 2.
[0018] The filter box includes a first filter box 3 and a second filter box 4. The bottom of the second filter box 4 is connected to the top of the first filter box 3 to realize the internal salt spray filtration operation.
[0019] Handles 5 are provided on both sides of the first filter box 3 and the second filter box 4 for easy handling.
[0020] The second filter box 4 has multiple filtration and demisting chambers arranged longitudinally at intervals, including a first filtration and demisting chamber 6 and a second filtration and demisting chamber 7 arranged from top to bottom. Adjacent filtration and demisting chambers are separated by mesh plates 8. Liquid and gas can pass through the holes of the mesh plates 8 respectively. The inner wall of the second filter box 4 is supported by pads 9 corresponding to the bottom edge of the mesh plates 8, so that the mesh plates 8 can be easily installed and removed.
[0021] Both the first filtration and demisting chamber 6 and the second filtration and demisting chamber 7 are filled with hollow filter spheres (not shown in the attached figure). The hollow filter spheres are made of adsorbent materials such as activated carbon to adsorb salt in the salt mist and release harmless gas.
[0022] The input pipe 1 is connected to the side wall of the second filter box 4 at the bottom of the second filter and demisting chamber 7, so as to send salt mist into the bottom to ensure complete salt mist filtration.
[0023] The second filter box 4 is equipped with a cover plate 10 on top and is connected to the output pipe 2. The cover plate 10 can be easily opened for internal maintenance and repair.
