[0017] Example:

[0018] Reference Figure 1-2 This embodiment demonstrates a scrubbing tower for silicon-containing organic exhaust gas, including a scrubbing tower body connected to a scrubbing liquid staged sedimentation and circulation module. The scrubbing tower body includes a lower air inlet module 7, and several fully packed scrubbing modules are arranged above the air inlet module 7. Each fully packed scrubbing module includes a packing layer that increases the scrubbing contact area, and a scrubbing layer is arranged corresponding to the packing layer. The several fully packed scrubbing modules form a multi-level fully contact scrubbing zone, which, together with the scrubbing liquid staged sedimentation and circulation module, circulates the scrubbing liquid to form a high-quality scrubbing treatment structure for silicon-containing organic exhaust gas. The top of the scrubbing tower body is provided with an exhaust port 23, and a backwash spray layer 1 is also provided corresponding to the exhaust port 23.

[0019] Corresponding to the exhaust port 23, a demisting filler layer 2 is also provided.

[0020] The air intake module 7, several fully packed washing modules, backwash spray layer 1, and demisting packing layer 2 are all equipped with manual inspection ports 22 for the washing tower.

[0021] Several fully-filled washing modules include at least a primary fully-filled washing module and a fully-filled washing module. The primary fully-filled washing module includes a primary filler layer 6 and a primary washing layer 5 used in conjunction. The secondary fully-filled washing module includes a secondary filler layer 4 and a secondary washing layer 3 used in conjunction.

[0022] The washing liquid classification sedimentation and circulation module includes a tank, inside which a primary separator 9 and a secondary separator 11 are installed to separate and form a primary separation chamber, a secondary separation chamber, and a tertiary separation chamber. A primary oil separator 16 and a secondary oil separator 14 are installed corresponding to the secondary and tertiary separation chambers. The tank is also equipped with several sludge discharge ports.

[0023] The sludge discharge ports include at least a primary sludge discharge port 17, a secondary sludge discharge port 15, and a tertiary sludge discharge port 13, which are set in three spaces corresponding to the primary oil separator 16 and the secondary oil separator 14.

[0024] The tank is equipped with a drain outlet 20 and a water inlet 18, as well as a chemical dosing port 19 and an inspection hole 21.

[0025] The primary separation chamber, secondary separation chamber, and tertiary separation chamber are equipped with oil level ports 8, 10, and 12 respectively, corresponding to the oil level in the tank.

[0026] Working principle:

[0027] 1) Silicon-containing organic waste gas enters the tower through waste gas inlet 7. It passes through primary packing layer 5, primary spray layer 6, secondary packing layer 4, and secondary spray layer 3 to achieve full contact between the waste gas and alkaline circulating liquid and undergo chemical reaction. After passing through demister packing layer 2 for gas-liquid separation, it is discharged through exhaust port and enters the subsequent treatment unit.

[0028] 2) After the circulating liquid comes into full contact with the exhaust gas, it reacts to produce silicone oil. The silicone oil-containing circulating liquid enters the bottom oil separator, which has two stages of oil separation. The silicone oil-containing circulating liquid first enters the primary separation chamber, and the silicone oil at the oil level flows out through the primary oil outlet 8. After passing through the primary oil separator 9, the circulating liquid enters the secondary separation chamber, and the silicone oil at the oil level flows out through the secondary oil outlet 10. The circulating liquid then passes through the secondary oil separator 11 and enters the tertiary separation chamber, where oil and water are separated. The silicone oil flows out through the tertiary oil outlet 12. After a certain operating time, sediment will form at the bottom of the oil separator. The sediment can be discharged through the bottom tertiary sludge outlet 13, secondary sludge outlet 15, and primary sludge outlet 17. The bottom primary baffle 16 and secondary baffle 14 ensure that the bottom sediment remains in the corresponding separation chamber, so that oil, water and sediment are separated step by step.

[0029] 3) When the system water level is insufficient, water is automatically replenished through inlet 18; when the system pH value does not meet the alkalinity requirement, chemicals are automatically replenished through dosing port 19. When the oil-water separator needs periodic cleaning, the inspection port 21 can be opened for cleaning. When the upper part of the scrubbing tower needs cleaning, the inspection manhole 22 can be opened for cleaning the packing and nozzles. When the demister layer needs cleaning, the top backwash spray layer 1 can be opened for flushing. The circulating liquid enters the circulating pump through drain port 20 and is pumped into the primary spray layer 5, secondary spray layer 3, and backwash spray layer 1 using pump power.

[0030] Compared with existing technologies, this invention combines the washing tower with the washing liquid oil-separated circulation by optimizing the tower structure, selecting high-efficiency packing and oil separation, which significantly improves the treatment efficiency of silicon-containing organic waste gas, reduces the footprint, and saves equipment manufacturing costs. It has the advantages of high removal rate, energy saving and environmental protection, and stable structure, and is suitable for a variety of industrial waste gas treatment scenarios.

[0031] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and all such modifications and improvements fall within the protection scope of this utility model.
