Abstract
Description
Technical Field
[0001] This utility model relates to the field of waste gas treatment technology, and in particular to a waste gas treatment device for esterification reaction. Background Technology
[0002] Esterification is a type of organic chemical reaction, mainly involving the reaction of alcohols with carboxylic acids or inorganic oxyacids to form esters and water. It is classified into three types: reactions of carboxylic acids with alcohols, reactions of inorganic oxyacids with alcohols, and reactions of strong inorganic acids with alcohols. Esterification is widely used in organic synthesis and other fields. During esterification, a large amount of harmful gases (sulfur oxides, hydrocarbons, nitrogen oxides, chlorine, benzene, etc.) are produced, necessitating waste gas treatment. Traditional waste gas treatment devices mostly rely on simple filtration through filter plates, failing to provide multi-stage treatment. This results in filtered waste gas failing to meet emission standards, affecting subsequent processing and reducing overall efficiency. Utility Model Content

The processing pulley 42 is connected to the transmission pulley via a belt. The processing motor 41 drives the processing pulley 42 to rotate via the belt.
[0037] Working principle: In use, first start the exhaust fan 3, which drives the air intake channel 4 to draw in external exhaust gas, so that the exhaust gas passes through the air outlet channel 2 and is discharged into the exhaust gas reaction tower 1. At the same time, start the fixed motor 12, which drives the two fixed worm gears 14 on the fixed rod 13 to rotate. The two fixed worm gears 14 mesh with their corresponding movable worm wheels 9, which drives the movable shaft 8 and movable baffle 10 on the movable worm wheel 9 to rotate, thereby controlling the speed of the exhaust gas inside the air intake channel 4. Then, the fixed rod 13 also drives the fixed pulley 15 to rotate. At the same time, the fixed pulley 15 is connected to the assembly pulley 6 via a belt, which drives the assembly shaft 5 and assembly baffle 7 on the assembly pulley 6 to rotate, thereby controlling the speed of the exhaust gas in multiple stages.
[0038] Then, the first pump 24 is started, which drives the second branch pipe 25 to draw the treatment liquid inside the purification reaction tower 16. The liquid passes through the first branch pipe 23, the second branch pipe 25 and the inlet pipe 20, and is discharged from multiple nozzles on the inlet pipe 20, thereby spraying and dust suppression treatment on the exhaust gas. The acidic substances in the exhaust gas are decomposed, and the waste liquid falls to the bottom of the exhaust gas reaction tower 1. Then, the mounting motor 27 on the L-shaped plate 26 is started, which drives the mounting gear 28 to rotate. Since the mounting gear 28 meshes with the auxiliary gear 21, it drives the inlet pipe 20 and the filter plate 22 on the auxiliary gear 21 to rotate, so that the filter plate 22 rotates and adsorbs and filters the exhaust gas, thereby regulating and spraying the exhaust gas to suppress dust.
[0039] Then, the exhaust valve on the exhaust branch pipe 19 is activated, allowing some of the exhaust gas that was not fully sprayed for dust suppression to be discharged into the purification reaction tower 16 through the exhaust branch pipe 19. Then, it is filtered and purified by the treatment liquid. Finally, the purification valve on the purification pipe 18 is activated, allowing the purified exhaust gas to be discharged.
[0040] Simultaneously, the waste liquid valve on the waste liquid pipe 35 is activated, followed by the activation of the second extraction pump 32. This causes the two waste liquid pipes 35 to extract waste liquid from the waste gas reaction tower 1 and the purification reaction tower 16 respectively. The waste liquid then passes through the extraction U-shaped pipe 34, the second extraction pipe 33, and the first extraction pipe 31 and is discharged into the treatment tank 30. The waste liquid then falls into the treatment shell 38 and undergoes double filtration through the filter screen layer 39 and filter cotton inside the treatment shell 38 before being discharged between the treatment tank 30 and the interior of the treatment tank 30. Next, the treatment motor 41 is activated, which drives the treatment pulley 42 to rotate. The treatment pulley 42 drives the treatment channel 37 on the transmission pulley and the treatment shell 38 to rotate centrifugally, thereby accelerating the filtration of waste liquid inside the treatment shell 38 and thus speeding up the centrifugal filtration of the waste liquid.
[0041] Finally, start the treatment outlet valve on the treatment outlet pipe 36, and then start the second pump 32 again. The second pump 32 drives the treatment outlet pipe 36 to extract the filtered waste liquid inside the treatment tank 30. The filtered waste liquid passes through the second pump pipe 33 and the first pump pipe 31. Then, close the first pump valve on the first pump pipe 31 and simultaneously start the third pump valve on the third pump pipe 43, so that the filtered waste liquid is discharged into the purification reaction tower 16, thereby recycling the waste liquid.
[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
