Description

Technical Field

[0001] This utility model relates to the field of waste gas treatment technology, and in particular to a catalytic oxidation waste gas treatment device. Background Technology

[0002] Catalytic combustion is a purification method that uses catalytic oxidants to oxidize and decompose combustible substances in waste gas at lower temperatures. Therefore, catalytic combustion is also known as catalytic chemical conversion. Because the catalyst accelerates the oxidation and decomposition process, most hydrocarbons can be completely oxidized at temperatures of 300-450℃. Compared with thermal combustion, catalytic combustion requires less auxiliary fuel and consumes less energy. However, the waste gas after the combustion reaction needs to be purified. Traditional waste gas treatment devices mostly lack structures for cooling waste gas. High-temperature waste gas can easily damage equipment. At the same time, the flue gas contains a lot of dust, which can easily clog pipes if not treated. In addition, existing devices have slow catalytic oxidation rates, incomplete reactions, and low efficiency, thus reducing their effectiveness. Utility Model Content

The drive gear 29 meshes with the adjusting gear 24. The drive motor 27 drives the drive rod 28 to rotate.

[0032] Working principle: In use, first install the exhaust gas channel 5 with the external channel, then the exhaust gas is discharged into the exhaust gas shell 4. Next, start the suction pump 15, which drives the second branch pipe 16 to draw water from the inside of the connecting tower 2. Then, start the condenser 17 on the second branch pipe 16 to condense the water. Then, the cold water is discharged into the first branch pipe 13. Next, start the auxiliary valve on the serpentine pipe 14 to allow cooling water to enter the serpentine pipe 14. Then, the high-temperature exhaust gas is cooled by conduction through the serpentine pipe 14, and then the cooled water is discharged into the connecting tower 2 for circulation cooling. Then, part of the cooled exhaust gas is discharged into the assembly tower 1 through the assembly channel 3. Then, another part of the cooling water is discharged into the assembly pipe 9 through the first branch pipe 13. Then, it is discharged into the assembly horizontal pipe from the assembly pipe 9 and then discharged from multiple assembly nozzles 12 on the assembly horizontal pipe to spray and suppress dust from the exhaust gas.

[0033] Following the start of the drive motor 27 on the drive bracket 26, the drive motor 27 drives the drive rod 28 and drive gear 29 to rotate. At the same time, the drive gear 29 meshes with the adjusting gear 24, causing the adjusting shaft 22 and adjusting fan blade 25 on the adjusting gear 24 to rotate. This causes the adjusting fan blade 25 to rotate and blow air. The air then comes into contact with the serpentine tube 14 for conduction and cooling. Simultaneously, the air comes into contact with the exhaust gas, blocking and slowing down the flow rate of the exhaust gas, causing heavier particulate impurities in the exhaust gas to fall into the receiving drawer 6. Then, the receiving drawer is pulled periodically as needed. Drawer 6 is used to clean impurities inside the material receiving drawer 6. At the same time, the adjusting shaft 22 also drives the adjusting pulley 23 to rotate the assembly pulley 10 via the belt. Then, the assembly pulley 10 drives the assembly centrifugal fan blade 11 on the assembly tube 9 and the multiple assembly nozzles 12 on the assembly horizontal tube to rotate, so that the exhaust gas is evenly sprayed to reduce dust. Then, the assembly centrifugal fan blade 11 accelerates the rise of the exhaust gas, so that the exhaust gas passes through the fixed filter screen 19, fixed filter element 20 and fixed filter cotton 21 inside the fixed housing 18 for three-stage filtration.

[0034] Next, the connecting valve on the connecting pipe 8 is activated, allowing the filtered waste gas to be discharged into the connecting tower 2 through the connecting pipe 8. Then, the waste gas is filtered through water. Finally, the inlet valve on the outlet pipe 7 is activated, allowing the purified gas to be discharged. Then, the first valve on the first installation pipe 32 and the second valve on the second installation pipe 33 are activated, allowing the waste liquid to be discharged into the processing shell 30 and filtered through the processing filter screen 31. Then, the waste liquid valve on the waste liquid pipe is activated, thereby discharging the filtered waste liquid.
