The composition of pollutants is complex, among which the odor mainly comes from malodorous substances such as carbon disulfide, styrene, hydrogen sulfide, and non-methane total hydrocarbons. If these waste gases are discharged without treatment, they will cause environmental pollution and harm the health of surrounding residents. Therefore, it is imperative to purify the waste gas generated by rubber mixing.

[0014] Depend on Figure 1 A vulcanization tail gas treatment device for rubber production is provided, comprising a base 1, a box body 2 is fixed on the base 1, an air inlet 3 is connected to the left side of the box body 2, a plurality of baffles 4 are staggeredly fixed in the box body 2, the plurality of baffles 4 divide the box body 2 into a first channel 5, a second channel 6 and a third channel 7, the first channel 5 is connected to the air inlet 3, a first spray plate 8 and a second spray plate 9 are installed in the box body 2, the first spray plate 8 is located at the intersection of the first channel 5 and the second channel 6, the second spray plate 9 is located at the intersection of the second channel 6 and the third channel 7, a UV photolysis device 10 located above the third channel 7 is installed in the box body 2, a first pipe 11 is connected to the top of the box body 2, the first pipe 11 is connected to a first filter tube 12 and a second filter tube 13, the lower end of the first filter tube 12 and the lower end of the second filter tube 13 are both connected to a second pipe 14, a fan 15 is installed on the base 1, the fan 15 is connected to the second pipe 14, and the other end of the fan 15 is connected to an outlet pipe 16.

[0015] A booster pump 17 is installed outside the box body 2 , and a treatment liquid is placed in the booster pump 17 . The first spray plate 8 and the second spray plate 9 are both connected to the booster pump 17 .

[0016] In order to facilitate the discharge of liquid at the bottom of the box body 2, a liquid outlet 18 is provided at the bottom of the box body 2.

[0017] In order to facilitate monitoring of the gas data discharged from the gas outlet pipe 16 , a gas sampling port 19 is provided in the gas outlet pipe 16 .

[0018] In order to remove water mist in the gas in the box 2 , a demister 20 is installed on the top of the box 2 . The demister 20 is located between the first pipeline 11 and the UV photolysis device 10 .

[0019] Activated carbon filter plates are installed inside the first filter tube 12 and the second filter tube 13. A first switch is provided above the first filter tube 12 to control the opening or closing of the first filter tube 12 and the first pipeline 11. A second switch is provided on the second filter tube 13 to control the opening or closing of the second filter tube 13 and the first pipeline 11.

[0020] When the utility model is in use, the fan 15, the UV photolysis device 10 and the booster pump 17 are turned on, and the booster pump 17 drives the first spray plate 8 and the second spray plate 9 to work. The vulcanized tail gas produced by rubber enters the first channel 5 in the box body 2 through the air inlet 3. When the vulcanized tail gas enters the corner of the first channel 5 and the second channel 6, the first spray plate 8 sprays the vulcanized tail gas. The treatment liquid is an alkaline liquid. The vulcanized tail gas blows upward and just encounters the water mist sprayed by the first spray plate 8. The water mist combines with the particulate matter and the sulfide gas in the exhaust gas to produce a neutralization reaction, forming a good gas-liquid intersection. Under the action of the air pressure, the gas enters the third channel 7 from the second channel 6. When the gas enters the second channel 6 and the third channel 7 At the corner, the second spray plate 9 sprays the gas again to achieve a double spray effect, which can fully neutralize the sulfurized tail gas and improve the purification quality. The gas moves upward, and the UV photolysis equipment 10 can release a high-energy UV ultraviolet light beam, which decomposes the oxygen molecules in the air to produce free oxygen (i.e., active oxygen). Because the positive and negative electrons carried by free oxygen are unbalanced, it needs to combine with oxygen molecules to produce ozone. Ozone has a strong oxidizing property. Ozone can perform a synergistic photolysis and oxidation on organic waste gas and malodorous gas, so that the organic waste gas and malodorous gas substances are degraded and converted into low molecular weight compounds, CO2 and H2O, which can further purify the sulfurized tail gas from rubber production;

[0021] Start the defogger 20, which can dehydrate and defog the gas, and the purified gas enters the first pipe 11. At this time, the switch of the first filter tube 12 is turned on, and the switch of the second filter tube 13 is in a closed state. The gas enters the second pipe 14 through the first filter tube 12. Under the action of the fan 15, a negative pressure is formed in the second pipe 14, which can quickly absorb the gas in the first filter tube 12. The activated carbon filter plate inside the first filter tube 12 can purify the gas again to ensure the purification quality of the gas. When the activated carbon filter plate in the first filter tube 12 needs to be replaced, the switch of the second filter tube 13 is turned on, and the switch of the first filter tube 12 is in a closed state. The gas will enter the second pipe 14 through the second filter tube 13, so that the activated carbon filter plate can be replaced without stopping the machine. The switching effect is good, which ensures the continuity of gas purification, and the purified gas is discharged to the outside through the outlet pipe 16.

Any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the utility model are within the protection scope of the technical solution of the utility model.
