Description

Technical Field

[0001] This utility model relates to the technical field of waste gas treatment equipment, specifically a multi-stage waste gas spray tower. Background Technology

[0002] Waste gas refers to toxic and harmful gases emitted during human production and daily life. Chemical plants, steel mills, pharmaceutical factories, coking plants, and oil refineries, in particular, emit waste gases with strong odors, severely polluting the environment and impacting human health. Spray towers, also known as scrubbing towers, are commonly used in waste gas treatment to remove harmful components from gases, primarily for absorbing acid mist during acid washing, desulfurization, and dust removal.

[0003] A multi-stage exhaust gas spray tower, with publication number CN217068344U, divides the tower body into several purification chambers using multiple baffles. This allows the exhaust gas to flow in a serpentine pattern within the tower, increasing the contact time between the exhaust gas and water mist. This ensures sufficient contact between the exhaust gas and the water mist in each purification chamber, thereby achieving multi-stage purification of the exhaust gas and guaranteeing its purification quality. Furthermore, the tower utilizes brushes to continuously clean the surface of the filter screen, preventing dust and debris from clogging it and affecting its filtration effect and efficiency. While highly practical, this design does not pre-treat the exhaust gas, potentially leaving particulate matter after spraying. Additionally, the lack of tiered treatment of the exhaust gas may result in incomplete treatment. Utility Model Content

A branch pipe 10 is fixedly connected to the side of the inlet pipe 8. A spray nozzle 11 is fixedly connected to the bottom of the branch pipe 10. The water pump 9 pumps alkaline liquid in the water tank 7, which then passes through the inlet pipe 8 and the branch pipe 10, and sprays the exhaust gas through the spray nozzle 11. The acidic substances in the exhaust gas neutralize with the alkaline liquid. The first collection assembly includes an outlet pipe 12. One end of the outlet pipe 12 is fixedly connected to a collection box 13. The top of the reaction box 3 is fixedly connected to...

[0028] Working Principle: During operation, exhaust gas is discharged into reaction chamber 3 through inlet pipe 4. Before entering reaction chamber 3, it passes through filter assembly 5. The filter screen 501 and activated carbon 502 inside filter assembly 5 remove fine particulate matter and odors from the exhaust gas. The pre-treated exhaust gas enters reaction chamber 3. Water pump 9 draws alkaline liquid from water tank 7, which then passes through inlet pipe 8 and branch pipe 10, and sprays the exhaust gas through spray nozzle 11. The acidic substances in the exhaust gas neutralize with the alkaline liquid. The reacted exhaust gas then enters reaction chamber 2 through inlet pipe 14. Inside the reaction chamber 15, an acidic liquid is pumped by a water pump 19 to spray the waste gas inside the reaction chamber 15. The acidic liquid neutralizes the alkaline substances in the waste gas. By controlling the concentration of the acidic and alkaline liquids, the substances in the waste gas can be neutralized. Multiple inclined plates are installed inside the reaction chamber to guide the liquid to flow down, increase the contact area between the liquid and the waste gas, and discharge it from the outlet pipe and collect it inside the collection box to avoid the accumulation of liquid in the reaction chamber, which would affect the subsequent treatment of the waste gas. The waste gas after the acid-base neutralization reaction passes through a demister 25 to remove water vapor from the gas.
