Description

Technical Field

[0001] This utility model relates to the field of desulfurization and denitrification technology, and in particular to an industrial flue gas desulfurization and denitrification device with high safety performance. Background Technology

[0002] Chemical production processes transform raw materials into products through chemical reactions. These processes generate large amounts of harmful gases. To avoid direct emissions that pollute the environment, these gases are often treated before release. Generally, industrial flue gas undergoes desulfurization and denitrification treatment. Flue gas desulfurization and denitrification technology is a boiler flue gas purification technology applied in chemical industries that generate nitrogen oxides and sulfur oxides. A commonly used method is catalytic oxidation, where the waste gas is reacted with appropriate chemical agents and catalysts to remove harmful components from the exhaust gas.

[0003] Existing desulfurization and denitrification devices cannot fully mix the chemical solution, and the chemical mist cannot fully contact the flue gas during treatment, resulting in incomplete desulfurization and denitrification of the flue gas. In addition, residual sludge after desulfurization and denitrification will settle and adhere to the bottom of the mixing device. If it is not cleaned, it will cause blockage at the waste liquid discharge point. Long-term blockage can easily damage the desulfurization and denitrification device and reduce the desulfurization and denitrification effect. Utility Model Content

[0026] First, desulfurizing and denitrifying chemicals for flue gas are introduced into the storage tank 2 through the inlet pipe 21 at the top of the storage tank 2 (the inlet pipe 21 is connected to an external device for storing water and desulfurizing and denitrifying chemicals; when chemicals and water need to be added, the external delivery pump is activated by the controller to input the chemicals and water into the storage tank 2). An appropriate amount of water is also added. Industrial flue gas is then introduced through the inlet pipe 10 (the inlet pipe 10 is connected to an external pipeline for transporting industrial flue gas; the external flue gas delivery device transports the industrial flue gas into the inlet pipe 10). Inside the processing tank 3, the second motor 17 is started to drive the drive gear disk 16 to rotate. The drive gear disk 16 drives the two driven gear disks 14 to rotate in opposite directions.

From there, the liquid is distributed through the three-way pipe 7 to two delivery pipes 9, and finally sprayed out by the atomizing nozzle 29, atomizing the liquid and allowing it to contact the flue gas. The opposite rotation of the two sets of levers 22 ensures sufficient contact between the atomized liquid and the flue gas. The treated flue gas exits through the exhaust pipe 12 (exhaust pipe 12 and the outer...) The exhaust pipe of the exhaust device is connected. When it is necessary to exhaust the flue gas, open the valve on the exhaust pipe to exhaust the flue gas. After the flue gas is treated, start the first motor 13 to drive the third rotating rod 26 to rotate, so that the connecting rod 28 drives the scraper 27 and the protective pad 30 (the protective pad 30 is made of rubber to prevent the scraper 27 from scratching the inner wall of the treatment tank 3) to rotate.

The operator can also start the external flue gas conveying device to transport the industrial flue gas into the inlet pipe 10, start the external storage device for water and desulfurization and denitrification chemicals to input the chemicals and water into the liquid storage tank 2, and start the external exhaust device to discharge the treated flue gas through the exhaust pipe, which facilitates desulfurization and denitrification operations.
