[0035] like Figures 1-6 As shown, this embodiment of the utility model provides a high-temperature corrosion resistant waste gas treatment device, including a treatment box 1 and an exhaust pipe 2.

Compared with conventional waste gas treatment devices in the prior art, which have low high-temperature and corrosion resistance and are easily damaged by the corrosion of waste gas after long-term use, thus affecting the application effect of the waste gas treatment device, this embodiment addresses the problem by using a water storage pipe... 3. The combination of spray nozzles 4, transmission gears 5, and swing mechanism enables the treatment of corrosive substances carried in the exhaust gas. At the same time, it can also achieve preliminary cooling of the exhaust gas, thereby reducing the damage caused by high-temperature exhaust gas carrying corrosive substances to the exhaust gas treatment equipment and extending the service life of the exhaust gas treatment equipment. Through the combination of air hood 6, air circuit one-way valve 7, protective shell 8, and cooling blower mechanism, secondary cooling of the exhaust gas is achieved, ensuring the cooling effect of the exhaust gas and further reducing the damage caused by high-temperature exhaust gas to the exhaust gas treatment equipment.

[0036] like Figure 2As shown, two water storage pipes 3 are rotatably installed inside the treatment box 1. Multiple spray nozzles 4 are connected to the water storage pipes 3, and are horizontally connected to the lower side of the water storage pipes 3. The spray nozzles 4 are inclined, which can accelerate the treatment of corrosive substances carried in the exhaust gas. Two drain valves 9 are connected to one side of the treatment box 1. A guide seat 10 is installed on the inner bottom wall of the treatment box 1. The guide seat 10 is a right-angled triangle and can guide the treated water to the drain valve 9, and then discharge it from the treatment box 1. A transmission gear 5 is installed on one end of the water storage pipe 3 via a connecting rod. The two transmission gears 5 mesh.

Figure 3 and Figure 6 As shown, the swing mechanism includes a turntable 101, a transmission plate 102, and a transmission component 103. The transmission component 103 consists of a connecting plate and two connecting seats. The two connecting seats are respectively installed on the upper and lower parts of the outer side of the connecting plate. The connecting seats are T-shaped and anti-derailment shaped. The upper connecting seat is located in the eccentric annular groove 1011 opened on the turntable 101, and the lower connecting seat is located in the sliding groove 1021 opened on the transmission plate 102.

[0037] like Figure 4 As shown, the vent shroud 6 is installed on the outside of the exhaust pipe 2. Multiple air inlets are arranged in a ring on the outside of the exhaust pipe 2 and communicate with the vent shroud 6. Cooled air can be evenly blown into the interior of the exhaust pipe 2 through the multiple air inlets. Two one-way valves 7 are connected to the outside of the vent shroud 6. Two protective shells 8 are installed on the outside of the exhaust pipe 2 via support rods. Switch valves are connected to the outside of the protective shells 8 for discharging or replenishing coolant. A cooling blower is installed inside the protective shells 8. A drying assembly is installed inside the exhaust pipe 2. The drying assembly includes a... The assembly consists of ring 201 and drying layer 202. The drying material inside drying layer 202 is silica gel (silica gel desiccant; silica gel desiccant is a variety of silica gel packaged in moisture-permeable pouches. The main raw material, silica gel, is a highly microporous hydrated silica, non-toxic, odorless, and tasteless, with stable chemical properties and strong hygroscopic properties, making it a highly active adsorbent material. It is usually produced by reacting sodium silicate with sulfuric acid, followed by a series of post-treatment processes such as aging and acid soaking). The silica gel drying layer 202 can rapidly adsorb moisture in the gas, and the drying assembly can dry the water vapor carried in the treated waste gas. Figure 5As shown, the cooling blower mechanism includes a baffle 301, a fan 302, and a cooling pipe 303. The cooling pipe 303 is multi-segmented and curved. Air flows through the multi-segmented and curved cooling pipe 303, which can increase the cooling time of the air by the coolant. The other end of the cooling pipe 303 is connected to an air inlet shroud 11. An intercepting net is installed inside the air inlet shroud 11. The air inlet shroud 11 can accelerate the intake speed of outside air, and the intercepting net can intercept outside dust. The cooperation of the air hood 6, the one-way valve 7, the protective shell 8, and the cooling blower mechanism can perform secondary cooling of the exhaust gas, ensuring the cooling effect of the exhaust gas.

[0038] Working principle:

[0039] Corrosive high-temperature exhaust gas enters the interior of treatment chamber 1 through the inlet pipe. During the intake process, the operator connects the external pipe to an external water supply system. The external water supply system delivers treatment water mixed with the reaction agent to the interior of the water storage pipe 3 through the external pipe. The treatment water is sprayed into the exhaust gas through the spray nozzle 4. The treatment water reacts with the corrosive substances in the exhaust gas. The corrosive substances in the exhaust gas are removed from the exhaust gas along with the treatment water and discharged from treatment chamber 1 through drain valve 9. During the treatment process, the forward and reverse motor is started, which drives the rotating shaft to rotate. The rotating shaft drives the turntable 101 to rotate. When the turntable 101 rotates, the T-shaped anti-detachment connecting seat located at the upper part of the transmission component 103 forms an eccentric annular groove 1011 on the turntable 101. When the turntable 101 moves, the upper T-shaped anti-detachment connecting seat can drive the lower T-shaped anti-detachment connecting seat to move in the groove 1021 opened on the transmission plate 102 via the connecting plate. When the lower T-shaped anti-detachment connecting seat moves downward along the groove 1021, it can drive the transmission plate 102 to deflect downward around the connecting rod. When the lower T-shaped anti-detachment connecting seat moves upward along the groove 1021, it can drive the transmission plate 102 to deflect upward around the connecting rod. This causes the turntable 101 to drive the transmission plate 102 to swing via the transmission component 103. The transmission plate 102 drives the water storage pipe 3 to swing via the connecting rod. The water storage pipe 3 drives the spray nozzle 4 to swing, causing the spray nozzle to swing. 4. The system can evenly spray the treated water into the exhaust gas entering the treatment chamber 1, achieving comprehensive treatment of corrosive substances in the exhaust gas and initial cooling of the high-temperature exhaust gas. The treated exhaust gas enters the exhaust stack 2. When the exhaust gas passes through the drying component, the silica gel in the drying layer 202 inside the drying component dries the water vapor in the exhaust gas. The dried exhaust gas flows upward. At this time, the fan 302 is started, and the fan 302 draws outside air into the cooling pipe 303. When the air flows inside the cooling pipe 303, it passes through the cooling area 3011. At this time, the air is inside the cooling pipe 303 and flows inside the cooling pipe 303. The coolant is outside the cooling pipe 303. Without direct contact with air, the coolant cools the air flowing inside through the cooling pipe 303. The air flowing inside the cooling pipe 303 is cooled by the coolant inside the cooling zone 3011 (the cooling zone 3011 is the area between the baffle 301 and the protective shell 8, where the coolant is located. The baffle 301 acts as a barrier to the coolant, and the coolant can be discharged or replenished through the switch valve installed on the protective shell 8). The cooled air is blown into the air hood 6 through the one-way valve 7, and then evenly blown into the exhaust pipe 2 through multiple air inlets, thus achieving secondary cooling of the exhaust gas. The treated exhaust gas is discharged from the exhaust gas treatment equipment through the exhaust pipe 2.
