Description

Technical Field

[0001] This invention belongs to the field of exhaust gas processing technology, specifically relating to an explosion-proof exhaust gas processor. Background Technology

[0002] An explosion-proof exhaust gas processor is a device for treating exhaust gases in explosive atmospheres. It mainly consists of a catalytic sleeve, heating element, heating rod, tee connector, junction box, and outer casing. For example, the SZTE-01Ex explosion-proof exhaust gas processor uses catalytic treatment technology, focusing on oxidizing hydrocarbons before emission while maintaining an atmospheric pressure baseline. This processor uses a continuous heat source to effectively oxidize intermittent or continuous sample gas, converting it into carbon dioxide and water vapor. Furthermore, this explosion-proof exhaust gas processor has passed the inspection and testing of the National Instrument and Meter Explosion-proof Safety Supervision and Inspection Station and can be used in some explosive environments.

[0003] However, in actual use, the existing explosion-proof exhaust gas processors mentioned above have a short gas circulation path due to the limited space inside the catalytic sleeve and the lack of a pipeline structure designed to extend the gas circulation path. This results in an inadequate catalytic reaction effect. Furthermore, the existing explosion-proof exhaust gas processor housing is connected to the catalytic sleeve via threads, which can easily lead to thread seizing and affect subsequent disassembly and assembly of the housing. Therefore, this invention improves upon the existing technology. Summary of the Invention

[0004] The purpose of this invention is to provide an explosion-proof exhaust gas processor to solve the problems of poor catalytic effect and difficulty in disassembling the outer casing of existing explosion-proof exhaust gas processors mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an explosion-proof exhaust gas processor, comprising a catalytic sleeve and a housing assembly installed outside the catalytic sleeve.

Multiple air holes are evenly opened on the surface of the venting pipes, and an air inlet is opened on the inner wall of the end of the protective sleeve, communicating with the inside of the venting pipes.

[0006] The outer casing assembly includes a casing cover, a casing cap, and a casing base. The casing cap and casing base are respectively installed at both ends of the casing cover. The casing base is sleeved on the casing base and is provided with a disassembly and assembly mechanism between the casing base and the casing base.

[0007] Preferably, the heating element includes a connector, a tube body, and a cap. The connector is sleeved and installed on the right end surface of the tube body, the cap is installed inside the left end of the tube body, and the heating rod is inserted into the inside of the tube body.

[0008] Preferably, the disassembly and assembly mechanism includes two insert blocks fixed to the outer surface of the sleeve base. The surface of the housing base has two slots. The interior of the housing base has a sliding groove one and a sliding groove two. A slide bar is slidably arranged in the sliding groove one. A limit block is fixed on one side of the slide bar. A limit hole is opened on the surface of the insert block. The end of the limit block passes through the limit hole. A slider is slidably arranged in the sliding groove two. The slider is fixed to the slide bar. The surface of the housing base also has a top sliding groove communicating with the sliding groove two. A pressing top plate is arranged in the top sliding groove and fixed to the other end of the slider. Two springs are connected between the pressing top plate and the inner wall of the top sliding groove. One end of the spring is fixed to the pressing top plate, and the other end of the spring is fixed to the inner wall of the top sliding groove. A through hole communicating with the slot is opened on one side of the inner wall of the sliding groove one. The through hole corresponds to the limit block.

[0009] Preferably, the disassembly and assembly mechanism further includes a top slide bar slidably disposed on the surface of the pressing top plate. Both sides of the inner wall of the top slide bar are provided with strip-shaped slots. A U-shaped seat is fixed on the surface of the pressing top plate. The top slide bar passes through the inside of the U-shaped seat. A guide block is fixed on the inner surface of the U-shaped seat. A guide groove is provided on the surface of the top slide bar. The guide block is slidably located in the guide groove.

[0010] Compared with the prior art, the beneficial effects of the present invention are as follows: The present invention improves the existing explosion-proof exhaust gas processor by designing a ventilation tube and other structures inside the catalytic sleeve, which effectively extends the gas circulation path into the catalytic sleeve and improves the catalytic reaction effect of the gas.

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Example 1

[0019] Please see Figures 1 to 3This is the first embodiment of the present invention, which provides a technical solution: an explosion-proof exhaust gas processor, including a catalytic sleeve 2 and a housing assembly 1 installed outside the catalytic sleeve 2. One end of the catalytic sleeve 2 is connected to a heating element 3 via a three-way connector 5. A heating rod 4 is installed inside the heating element 3. The other end of the heating element 3 is connected to a junction box 6. The junction box 6 has four terminals for connecting the power supply wires of the heating rod 4. A gland connector 7 is provided on one side of the junction box 6, through which the power cable is introduced. The catalytic sleeve 2 includes a base 21, a protective sleeve 22, a protective mesh 23, and a catalytic body cover 24. The protective sleeve 22, which is sintered from powder metallurgy, is installed at the end of the base 21 and communicates with the base 21. Air can enter the interior of the protective sleeve 22 from the base 21 for flameless combustion catalysis. Hydrogen compounds are oxidized and decomposed into carbon dioxide and water vapor, which are emitted into the atmosphere through the outer shell assembly 1, thereby achieving the purpose of removing hydrocarbons from the exhaust gas. The protective net 23 is installed on the outside of the protective sleeve 22, the catalyst cover 24 is fitted on the outside of the protective net 23 and connected to the sleeve 21, and the heating element 3 is inserted into the inside of the protective sleeve 22. The inner side of the protective sleeve 22 is provided with ventilation tubes 221 on both sides of the heating element 3. Multiple air holes 222 are evenly opened on the surface of the ventilation tubes 221, and the inner wall of the end of the protective sleeve 22 is provided with an air inlet 223 that communicates with the inside of the ventilation tubes 221, so that the gas entering the inside of the protective sleeve 22 can also enter the ventilation tubes 221 through the air inlet 223, extending the gas circulation path and improving the catalytic reaction effect of the gas.

[0020] The outer casing assembly 1 includes a casing 11, a casing cover 12, and a casing base 13. The casing cover 12 and the casing base 13 are respectively installed at both ends of the casing 11. The casing base 13 is sleeved on the sleeve base 21, and a disassembly and assembly mechanism 8 is provided between the casing base 13 and the sleeve base 21.

[0021] The heating element 3 includes a connector 31, a tube body 32, and a cap 33. The connector 31 is fitted onto the right end surface of the tube body 32 and is used to connect to the junction box 6 and the tee connector 5. The cap 33 is installed inside the left end of the tube body 32, and the heating rod 4 is inserted into the inside of the tube body 32.

[0022] Example 2

[0023] Please see Figures 1 to 4 This is the second embodiment of the present invention. This embodiment is based on the previous embodiment, but the difference is that the disassembly and assembly mechanism 8 is designed to facilitate the quick disassembly and assembly of the outer shell assembly 1.

[0024] Specifically, the disassembly and assembly mechanism 8 includes two insert blocks 801 welded and fixed to the outer surface of the sleeve 21. The surface of the housing 13 has two slots for inserting the insert blocks 801. The interior of the housing 13 has a first sliding groove 802 and a second sliding groove 803. A slide bar 805 is slidably disposed in the first sliding groove 802, and a limit block 806 is fixed to one side of the slide bar 805. The surface of the insert block 801 has a limiting hole 807 corresponding to the limiting block 806, and the end of the limiting block 806 passes through the limiting hole 807, thereby stably limiting the insert block 801 and ensuring a stable connection between the housing 13 and the sleeve 21. A slider 804 is slidably disposed in the second sliding groove 803, and the slider 804 is welded and fixed to the slide bar 805. The surface of the housing 13 also has a corresponding sliding groove 804. The top slide groove 808 is connected to the top slide groove 803, and a pressing top plate 809 fixed to the other end of the slider 804 is provided in the top slide groove 808. By pressing the pressing top plate 809, the slider 804 moves with the slide bar 805 and the limiting block 806 moves out of the limiting hole 807, so that the shell 13 and the sleeve 21 can be quickly separated. Two springs 810 are connected between the pressing top plate 809 and the inner wall of the top slide groove 808 for the springback reset after the pressing top plate 809 is pressed. One end of the spring 810 is fixed to the pressing top plate 809, and the other end of the spring 810 is fixed to the inner wall of the top slide groove 808. A through hole communicating with the slot is opened on one side of the inner wall of the slide groove 802, and the through hole corresponds to the limiting block 806, so that the limiting block 806 can pass smoothly through.

[0025] Example 3

[0026] Please see Figures 1 to 5 This is the third embodiment of the present invention. This embodiment is based on the previous embodiment, but the difference is that by designing a slidable top slide bar 811, the top plate 809 can be assisted in limiting its position by sliding the top slide bar 811 after it is pressed down, thereby further improving the ease of disassembly and assembly of the outer shell assembly 1.

[0027] Specifically, the disassembly and assembly mechanism 8 also includes a top slide bar 811 slidably disposed on the surface of the pressing top plate 809. Both sides of the inner wall of the top slide groove 808 are provided with strip-shaped slots 813 for the top slide bar 811 to be inserted. This allows the operator to push one end of the top slide bar 811 into the strip-shaped slot 813 after pressing the pressing top plate 809, thus preventing the pressing top plate 809 from rebounding and facilitating the disassembly and assembly of the housing 13. A U-shaped seat 812 is fixed on the surface of the pressing top plate 809. The top slide bar 811 passes through the inside of the U-shaped seat 812, so that the top slide bar 811 will not separate from the pressing top plate 809. A guide block is fixed on the inner surface of the U-shaped seat 812. A guide groove is provided on the surface of the top slide bar 811. The guide block slides in the guide groove, so that the top slide bar 811 can be guided when sliding.

[0028] Although embodiments of the invention have been shown and described (see the detailed description above), 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 invention, the scope of which is defined by the appended claims and their equivalents.
