Description

Technical Field

[0001] This utility model relates to the field of desulfurization and denitrification technology, and in particular to a tower-type desulfurization and denitrification device. Background Technology

[0002] In today's industrial sector, especially in energy production and chemical manufacturing, the exhaust gases produced during combustion contain large amounts of harmful sulfur oxides (mainly sulfur dioxide) and nitrogen oxides (such as nitric oxide and nitrogen dioxide).

The intelligent control panel 7 is electrically connected to the servo motor 3, the two pressurized water pumps 10, the air pump 13, and the gas sensor 24. Open air valve 5 and start air pump 13. The gas to be processed enters the inner tank 22 through air inlet pipe 21. At this time, gas sensor 24 monitors the composition and concentration of the incoming gas in real time and transmits the data to intelligent control panel 7. Intelligent control panel 7 determines whether the gas is qualified according to preset standards. If the gas is qualified, intelligent control panel 7 controls air pump 13 to maintain its current operating state, and the gas continues to flow in the device. If the gas is unqualified, intelligent control panel 7 records the data and prepares for subsequent processing. When gas sensor 24 detects that the gas is unqualified, intelligent control panel 7 immediately activates the valve on the extraction pipe 12, which can be connected to intelligent control panel 7. With automatic control, the air pump 13 reverses, drawing the substandard gas back into the inner tank 22 through the suction pipe 12 for reprocessing. During this process, the intelligent control panel 7 adjusts the power of the air pump 13 based on the gas composition and concentration data fed back by the gas sensor 24, ensuring that the gas can re-enter the inner tank 22 at a suitable flow rate and volume to improve the processing effect. At the same time, the intelligent control panel 7 can adjust the rotation angle and speed of the servo motor 3 and the pressure of the pressurized water pump 10 as needed. For example, by controlling the servo motor 3 to make the rotating part 25 rotate back and forth within a specific angle range, the water mist sprayed by the nozzle 19 can come into more comprehensive contact with the gas, enhancing the reaction effect.Alternatively, the pressure of the pressurized water pump 10 can be adjusted to make the sprayed water mist particle size more suitable for reacting with pollutants in the gas, promoting the desulfurization and denitrification reaction. During the gas circulation process in the inner tank 22 and the outer tank 8, the water spray system continues to work. The servo motor 3 drives the rotating part 25 to rotate according to the set program. Water from the water tank 9 is transported to the rotating part 25 through the water pipe 4, and then sprayed out by multiple nozzles 19. The appropriate length of the water pipe 4 selected by the user ensures that it will not entangle during rotation, ensuring normal water delivery. The sprayed water mist is fully mixed with the gas to carry out the desulfurization and denitrification reaction. The gas circulates continuously in the gas purification mechanism. After multiple contacts and reactions with the water mist, pollutants such as sulfur oxides and nitrogen oxides are gradually removed. The gas sensor 24 continuously monitors the changes in gas composition and concentration. The intelligent control panel 7 adjusts the operating parameters of each component according to real-time data to ensure that the gas purification effect reaches the best. When the gas sensor 24 detects that the gas has reached the qualified standard after treatment, the intelligent control panel 7 controls the gas purification process. The gas pump 13 discharges the purified gas through the outlet pipe 6. After the device has been running for a period of time, maintenance is required. Turn off the power, stop all components, and check for looseness or damage in detachable parts such as connectors 23. If necessary, unscrew bolts or loosen connections for inspection and repair. Regularly calibrate and clean the gas sensor 24 to ensure its accuracy. Check for blockages in the nozzle 19; if blocked, remove the nozzle 19 for cleaning or replacement. Simultaneously, check the water level in the water tank 9. If the water level is below the set lower limit, replenish water promptly. Inspect the device's appearance, checking the outer tank 8, pipes, etc., for corrosion or damage. Repair or replace any problematic parts to ensure long-term stable operation. Furthermore, since the length of the water pipe 4 is selected by the user based on actual conditions, check for wear or aging during maintenance. Replace the water pipe 4 if necessary to ensure normal device operation.
