Technical Field

[0001] The utility model relates to the technical field of methane chloride purification, in particular to an environment-friendly cyclone spray acid mist removal tower for methane chloride preparation. Background Technique

[0002] The environment-friendly cyclone spray acid mist removal tower for methane chloride preparation is a device specifically used for treating and purifying acid waste gas in the production process of methane chloride. It effectively removes acid mist in the waste gas through the technologies of cyclone separation and spray absorption, protecting the environment from the pollution of acid gas. Its working principle is to use the rotating airflow to throw the acid mist particles in the waste gas towards the tower wall, and neutralize the acidic substances with the alkali liquid sprayed by the spray system. The purified gas is discharged from the top of the tower, and the spray liquid and the neutralized acidic substances fall into the liquid collection tank at the bottom of the tower for recovery or treatment. This device not only improves the environmental protection of the production process but also reduces the risk of environmental pollution. It is an indispensable environmental protection device in modern industrial production.

[0003] At present, during the operation of the cyclone spray acid mist removal tower, there may be a problem of uneven mixing of acid mist and alkali liquid. The short-circuit flow will cause the residence time of the gas in some areas to be too short, resulting in a limited contact time between methane chloride and the alkali liquid, thus affecting the progress of the neutralization reaction and making the quality of methane chloride purification by the spray acid mist removal tower limited. Therefore, an environment-friendly cyclone spray acid mist removal tower for methane chloride preparation is proposed. Content of the Utility Model

The liquid inlet pipe 8 penetrates through the inside of the tower top 3 and extends into the tower body 1. Fourteen spray heads 9 are fixedly installed on the outer peripheral wall of the liquid inlet pipe 8. A fan 10 is fixedly installed on the top of the liquid collection tank 7. The air inlet end and the air outlet end of the fan 10 are respectively fixedly installed with an air inlet pipe 11 and an exhaust pipe 12. Two mounting rods 13 are fixedly installed on the inner peripheral wall of the tower bottom 2. A mounting seat 14 is fixedly installed between the two mounting rods 13. A rotating shaft 15 is rotatably connected inside the mounting seat 14. Two limiting rings 16 are fixedly installed on the outer peripheral wall of the rotating shaft 15. A through hole is formed inside the mounting seat 14. The rotating shaft 15 is rotatably connected inside the through hole and is of a suitable size.

[0026] The two limiting rings 16 are respectively rotatably connected to the outer walls of the top and bottom of the mounting seat 14. Two fan blades 17 are fixedly installed on the outer peripheral wall of the rotating shaft 15. The exhaust pipe 12 penetrates through the outer peripheral wall of the tower bottom 2 and extends into the interior. The exhaust pipe 12 is located directly below the mounting seat 14, the rotating shaft 15, and the fan blades 17. Six partition plates 18 are fixedly installed on the outer peripheral wall of the liquid inlet pipe 8. Ten ventilation holes are formed inside the partition plates 18.

[0032] When purifying the gas containing methyl chloride, the fan 10 is started at this time to drive the air flow inside the tower body 1, the tower bottom 2 and the tower top 3. At the same time, the gas will drive the fan blades 17 to rotate. At this time, the gas containing methyl chloride can be input into the inside of the tower bottom 2, and then the lye is sprayed out through fourteen nozzles 9 through the liquid inlet pipe 8. At the same time, the gas containing methyl chloride will be input into the purification chamber. At this time, after being restricted, the gas containing methyl chloride will be fully mixed with the lye. Driven by the bottom gas, the gas containing methyl chloride moves upward from bottom to top for sufficient purification treatment, and finally is discharged through the exhaust seat 6.
