Technical Field
[0001] The utility model relates to the technical field of methane chloride tail gas treatment, in particular to a conveying device for methane chloride tail gas treatment. Background Art
[0002] Methane chloride, also known as chloromethane, is a product in which the hydrogen atoms in the methane molecule are replaced by chlorine atoms. It includes four compounds. Methane chloride is the general term for four products including monochloromethane, dichloromethane, trichloromethane and carbon tetrachloride, abbreviated as CMS. It is the second largest chlorine-based product among organic products after vinyl chloride and is an important chemical raw material and organic solvent.
[0003] Chinese patent CN218422006U discloses a tail gas absorption device for a methane chloride generating tower. The patent discloses a technical solution for improving absorption efficiency, which solves the problem that existing methane chloride tail gas treatment devices only use a falling film absorption tank and a spray assembly for absorption, and can only rely on the flow of water to cause the gas reaction, which increases the reaction time and causes the absorption time to be prolonged. At the same time, activated carbon is generally used for re-filtration, and the existing activated carbon filter plate is difficult to remove.
[0004] When the device is in use, the absorption efficiency is accelerated by the action of the mixing component. However, after the gas is filtered by the activated carbon filter disc, it is directly discharged to contact the atmosphere, which makes it inconvenient to detect the absorbed gas. If the tail gas is not treated to the qualified standard, it is easy to pollute the atmosphere and reduce the treatment effect. Therefore, a conveying device for treating methane chloride tail gas is proposed to solve the above problems. Utility Model Content

[0030] Specifically, the gas enters the interior of the installation box 13 through the first connecting pipe 6 and the second connecting pipe 10, and the gas detector 17 detects the gas inside the installation box 13. If the gas is qualified, the first solenoid valve 9 is started and the gas is discharged from the installation box 13 through the exhaust pipe 8.
