Abstract

The invention discloses a water washing tank for methanol gas and a method for washing methanol gas. The washing tank is provided with a horizontal tank body (1), and the horizontal tank body is provided with a methanol-containing gas inlet pipe (4), a washing water inlet pipe (2), a purified gas outlet pipe (3) and an overflow water outlet pipe (14 ). The inner cavity of the horizontal tank body is provided with a first buffer space top plate (6), a second buffer space bottom plate (9), a second buffer space top plate (11) and a riser tube plate (12) from bottom to top. The inner cavity of the horizontal tank body is divided into a first buffer space (5), a water bath space (15), a second buffer space (16), a shower space (17) and a space (18) above the riser tube plate. The washing tank is also provided with an ascending pipe (7), a descending pipe (8), a connecting pipe (10) and a standpipe (13). The invention discloses a method for washing methanol-containing gas by using the water washing tank. The invention is mainly used for washing methanol-containing gas in industries such as petrochemical industry.

Description

technical field [0001] The invention belongs to the technical field of gas purification, and relates to a water washing tank for methanol-containing gas and a method for washing methanol-containing gas. Background technique [0002] Methanol is the simplest saturated monohydric alcohol, and it is widely used in the petrochemical industry. Methanol is toxic and harmful to the human body and should be taken seriously. The storage tanks used to store methanol in the petrochemical industry are often sealed with nitrogen. When the storage tank is discharged under overpressure, it will emit harmful methanol-containing gas (a mixture of methanol gas and nitrogen gas), which must be purified before it can be discharged into the atmosphere. At present, methanol and water are often used to treat methanol-containing gas by washing with water, which is completely miscible with water. Chinese patent CN104275073A discloses a method and device for absorbing methanol gas. A methanol gas p...
