Description

Technical Field

[0001] This invention relates to the field of exhaust gas treatment, and in particular to an air-cooled combustion exhaust gas treatment device. Background Technology

[0002] Existing combustion-type semiconductor exhaust gas treatment systems use flames to burn harmful gases in the exhaust gas, thereby reducing their concentration and facilitating further processing. After combustion, a water-filled chamber is typically placed below the combustion chamber to absorb residual harmful substances and lower the exhaust temperature. As the combusted exhaust gas passes through the water layer, the water absorbs residual harmful substances and lowers the exhaust gas temperature, facilitating subsequent discharge. After the water layer absorbs a certain volume of exhaust gas, it needs to be replaced with fresh water; the previous water, as wastewater, requires separate storage and harmless treatment. Due to the large water consumption of the exhaust gas treatment device, wastewater storage and treatment costs are high.

While ensuring the temperature of the emitted mixed gas meets standards, it maintains a low flow rate and a high exhaust gas concentration, which is beneficial for dust settling in the exhaust gas; the use of a spiral plate increases the exhaust gas flow path... The increased distance between the exhaust gas and the packing increases the amount of dust settling. After the packing is saturated with dust, maintenance is performed. The rotating spiral plate drives the packing to move and rub against each other, the one-way mechanism scrapes the surface of the packing, and the packing collides with the hollow shaft, causing the spiral plate to vibrate and drive the packing to vibrate. This removes the dust attached to the inner and outer sides of the packing. The operation is simple and improves the dust adsorption efficiency in subsequent operations. By absorbing the waste heat generated by the combustion of natural gas in the first annular cavity, the air temperature is increased, making the natural gas ignition smoother. The heated air continues to participate in combustion, increasing the calorific value and reducing fuel consumption. Attached Figure Description

The first air intake pipe 21 is fixedly connected to the frame 1, and the two ends of the first corrugated pipe 22 are fixedly connected to the first air intake pipe 21 and the air intake pipe of the ignition tube 2, respectively. By using the first corrugated pipe 22, which is telescopic and flexible, the ignition tube 2 can move relative to the frame 1 without disassembling the pipe, reducing disassembly work during maintenance.

[0060] More preferably, it also includes a second air intake pipe 31 and a second corrugated pipe 32. The second air intake pipe 31 is fixedly connected to the frame 1, and the two ends of the second corrugated pipe 32 are fixedly connected to the second air intake pipe 31 and the air intake pipe of the combustion cylinder 3, respectively. By using the telescopic and flexible second corrugated pipe 32, the combustion cylinder 3 can move relative to the frame 1 without disassembling the pipes, reducing disassembly work during maintenance.

[0061] More preferably, it also includes a third corrugated pipe 41, the two ends of which are fixedly connected to the connecting cylinder 4. The corrugated pipe between the two connecting cylinders 4 facilitates the adjustment of the position between the two connecting cylinders 4, so that when the two connecting cylinders 4 are fixed to the combustion cylinder 3 and the first adsorption cylinder 5 respectively, a larger positional error can be tolerated, reducing the difficulty of installation.

[0062] More preferably, the connecting mechanism is a C-clamp, which clamps and fixes the two flanges.

[0063] When maintenance is required, first disconnect the connecting mechanism of the upper and lower flanges of the combustion cylinder 3, releasing the combustion cylinder 3 from the ignition cylinder 2 and the first air-cooled cylinder 42. Then, extend and hold the piston rod of cylinder 91, raising the ignition cylinder 2 to a certain height to create a gap between it and the combustion cylinder 3. Next, push the combustion cylinder 3 backward along the guide rail 92, moving it away from the gap between the ignition cylinder 2 and the first air-cooled cylinder 42. At this point, the operator can observe whether the internal structure of the ignition cylinder 2 and the connecting cylinder 4 is normal and whether cleaning is needed; the operator can then clean and repair them. Afterward, rotate the combustion cylinder 3 around the rotation axis of the two coaxial rollers 93, tilting the vertical combustion cylinder 3 to facilitate inspection and maintenance of its interior. Before pushing the combustion cylinder 3 backward, all nuts below the mounting plate 13 can be rotated to create a gap between the first air-cooled cylinder 42 and the combustion cylinder 3, facilitating subsequent pushing and observation of the combustion cylinder 3.

[0064] After maintenance, rotate the combustion cylinder 3 to a vertical position and push it forward between the ignition cylinder 2 and the first air-cooled cylinder 42. If necessary, the first air-cooled cylinder 42 can be reset. Then, the piston rod of cylinder 91 moves downwards, placing the ignition cylinder 2 onto the combustion cylinder 3. Finally, use C-clamps to connect the upper and lower flanges to complete the fixing and sealing.

[0065] During exhaust gas treatment: Natural gas passes sequentially through natural gas connector 231, connecting pipe 25, and the interior of inner burner 26. Air passes sequentially through first air connector 232, first annular cavity 201, first gap 203, the interior of ceramic burner 27, and the interior of inner burner 26. Inside inner burner 26, natural gas and air mix. An electric arc is generated between ignition rod 29 and inner burner 26, igniting the natural gas. The ignited flame extends downwards through ceramic burner 27 and outer sleeve 28 into combustion chamber 3, igniting the exhaust gas entering through exhaust gas inlet pipe 241. During natural gas combustion, the air does not directly enter the interior of ceramic burner 27 but first passes through first annular cavity 201 to absorb heat, raising its temperature and preventing ignition difficulties caused by excessively low air temperature. Simultaneously, the air layer in first annular cavity 201 can block some heat, reducing the temperature of the flowing water in second annular cavity 202.

[0066] The exhaust gas and air are burned in the combustion chamber 3, where harmful gases are burned and decomposed, thus eliminating the harmful gases.

[0067] The exhaust gas after combustion moves downwards and enters the first air-cooled cylinder 42 through the opening at the top. The first valve 44 opens, and the first fan 48 sends air into the first air-cooled cylinder 42, where the air and exhaust gas mix for the first time, lowering the overall temperature. The gas after the first mixture flows along the third corrugated pipe 41 into the second air-cooled cylinder 43. The second valve 45 opens, and the second fan 49 operates to send air into the second air-cooled cylinder 43, where the air and exhaust gas mix for the second time, further lowering the exhaust gas temperature (usually below 50°C) to meet emission standards.

[0068] After the exhaust gas is cooled by mixing with air in the first air-cooling cylinder 42 and the second air-cooling cylinder 43, it enters the first adsorption cylinder 5. At this time, the motor 53 is not working, and the hollow shaft 81, the spiral plate 82, and the first adsorption cylinder 58 are relatively stationary, forming a spiral air duct filled with packing material. The exhaust gas enters the air duct from the lower perforated plate 51 and spirals upward along the air duct until it passes through the upper perforated plate 51. During the spiral movement of the exhaust gas, the packing material comes into contact with the exhaust gas, some dust from the exhaust gas remains on the surface of the packing material, and the catalyst on the packing material catalyzes the exhaust gas. The packing material can be made of metal Raschig rings or golf ball-shaped packing, and the catalyst is placed inside the Raschig rings or in the grooves on the surface of the golf ball-shaped packing.

[0069] The air-cooled assembly 4 controls the opening and speed of two sets of valves and fans based on two temperature sensors. While ensuring the temperature at the outlet of the exhaust pipe 7 meets the standard, it minimizes the opening and speed, reducing the exhaust gas velocity and avoiding excessive dilution of the exhaust gas proportion in the mixed gas. This allows the exhaust gas to have maximum contact with the packing surface as it subsequently enters the first adsorption cylinder 5, ensuring that the dust it carries is fully adsorbed and settled on the packing surface, and that harmful components fully contact the catalyst, reducing the content of dust and harmful gases in the emitted mixed gas. The spiral-shaped air duct also reduces the airflow velocity and increases the flow distance, thereby increasing the contact between the exhaust gas and the packing.

[0070] Finally, the exhaust gas passes through the second adsorption cylinder 6 and the outlet cylinder 7 before being discharged. The second adsorption cylinder 6 also includes upper and lower perforated plates, which may or may not be filled with packing material depending on the type of exhaust gas and emission requirements.

[0071] During maintenance: After shutdown, no exhaust gas enters, and combustion is not performed. At this time, the fans of the air-cooled assembly 4 and the third fan reverse, causing the airflow direction of the first adsorption cylinder 58 to be from top to bottom. A filter screen is installed at the end of the fan closest to the first adsorption cylinder 58 to reduce dust entry.

[0072] Then, the third motor 53 operates, driving the hollow shaft 81 and the spiral plate 82 to rotate. The rotating spiral plate 82 drives the packing material to move upward. During the upward movement of the packing material, the packing material collides and rubs against each other, and dust is removed from the surface of the packing material. Since the packing material cannot pass through the orifice plate 51, after moving to the top, the packing material will pass through the first through hole 811 above and enter the interior of the hollow shaft 81. Inside the hollow shaft 81, the packing material moves downward under gravity, passes through the one-way mechanism, falls to the bottom of the hollow shaft 81, and flows out from the first through hole 81 below along the conical surface at the bottom of the hollow shaft 81 to the top of the orifice plate 51 below, where it continues to be driven upward by the spiral plate 82, and so on.

[0073] As the packing passes through the one-way mechanism, the silicone flaps or baffles 84 scrape the packing, further removing dust from its surface. When the packing collides with the bottom of the hollow shaft 81, it causes vibration in both the shaft and the spiral plate 82. This vibration drives vibration in other packing components in contact with the spiral plate 82, further removing dust adhering to the surface and interior of the packing. Removing this dust improves the packing's dust adsorption efficiency and simultaneously strips dust from the catalyst surface, allowing the catalyst to fully contact and react with the exhaust gas.

[0074] The stripped dust moves downwards until it passes through the perforated plate 51 below and falls into the second air-cooling cylinder 43. After the dust removal operation is completed, the third motor 53 stops first, and then the fan stops working. After waiting for a period of time for the dust to settle sufficiently, the sealing plates of the first row of ash pipes 422 and the second row of ash pipes 432 are opened, and the dust in the first air-cooling cylinder 42 and the second air-cooling cylinder 43 is removed using a vacuum cleaner or other tools.

[0075] The present invention has been described above by way of example, but the present invention is not limited to the specific embodiments described above. Any modifications or variations made based on the present invention shall fall within the scope of protection claimed by the present invention.
