Description

Technical Field

[0001] The utility model relates to the technical field of dimethyl disulfide production, in particular to a multiple purification mechanism for a tail gas purification tower used in dimethyl disulfide production. Background Technique

[0002] Dimethyl disulfide is a light yellow liquid chemical substance. During the production process through chemical reactions, a large amount of polluting tail gas will be generated. The main polluting gases in the tail gas include dimethyl disulfide ether, methyl sulfide, methyl mercaptan, etc. With strong pollution, direct emission will cause serious damage to the atmosphere. Therefore, during the production of dimethyl disulfide, the processing plant uses a purification tower structure to treat the production tail gas and reduce environmental pollution.

[0003] For example, the publication number CN212327838U discloses "A multiple purification mechanism for a tail gas purification tower in dimethyl disulfide production". In this device, it includes a cooling tank and an electric telescopic rod. A sealing cover is installed at the upper end of the cooling tank. A reaction tube and a collection box are fixedly installed inside the oxidation tank. A condensing curved tube is fixedly installed on the inner side surface of the cooling tank. A top cover is installed at the upper end of the temperature transmitter. Exhaust pipes are fixed on both sides of the upper surface of the adsorption tank. And a working box is welded on the lower surface inside the adsorption tank. A middle rotating shaft is rotatably connected to the middle position at the upper end of the working box. And the middle rotating shaft is connected to the built-in tube through a fixing block. The electric telescopic rod is fixedly installed on the outer side surface of the fixing block. This multiple purification mechanism for the tail gas purification tower in dimethyl disulfide production adopts a new structural design, making this device convenient for multiple classification purification and processing of tail gas, and facilitating the cleaning of pollutants concentrated inside the device after purification and processing.

[0004] Although the above purification mechanism has certain advantages in purification effect, it still has certain drawbacks: when using the above purification device, when the activated carbon in the adsorption tank is in use, it always starts from the bottom. In this way, it is easy for the activated carbon at the bottom to be used for adsorption multiple times, while the adsorption use of the activated carbon on the upper side is less. As a result, it is easy to reduce the service life of the activated carbon at the bottom, thereby affecting the adsorption effect of the activated carbon, and further affecting the purification effect, making it easy for the tail gas purification to fail to meet the standard and affecting its emission.

[0029] Second, during use, the exhaust gas is introduced into the purification tower main body 1 from the air inlet 2. The exhaust gas first passes through the spraying device 4 for preliminary purification. The spraying device 4 sprays water to react with the exhaust gas to conduct preliminary purification on it;

[0030] Third, the purified exhaust gas floats into the filling shell 61. The motor 63 is started. The motor 63 drives the rotating rod 64 to rotate.
