Method for recovering and processing isobutyraldehyde tail gas of storage tank and apparatus thereof

Abstract

The present invention discloses an apparatus for recovering and processing isobutyraldehyde tail gas of storage tanks. A nitrogen tank (1) is communicated with a storage tank (3) through a gas pipeline I (5). The storage tank (3) is communicated with a reactor tank (8) through a gas pipeline II (6). A nitrogen valve (2) and a one-way valve (4) are disposed on the gas pipeline I (5) and the gas pipeline II (6). The reactor tank (8) is communicated with a water tank (9) through a gas pipeline III (7). The present invention also provides a method for recovering and processing, including: firstly, replenishing nitrogen to the storage tank (3) for storing isobutyraldehyde to make the nitrogen float on the liquid to form a nitrogen sealing; and secondly, discharging the mixed gas containing nitrogen and isobutyraldehyde tail gas in the reaction tank (8) into a methanol solution in the reactor tank (8) through an exhaust nozzle (11). The isobutyraldehyde tail gas in the mixed gas is adsorbed and dissolved by the methanol solution, and the residual nitrogen after floating is discharged into the water tank (9) for collection through the gas pipeline III (7).

Description

technical field [0001] The invention relates to a method and a device for recovering and treating isobutyraldehyde tail gas of a storage tank. Background technique [0002] At present, the tail gas in the gas storage tank for storing isobutyraldehyde is often directly discharged into the air through the breathing valve. Because the tail gas contains isobutyraldehyde gas and nitrogen, it will not only pollute the environment and be harmful to the human body, but also the materials in the storage tank High loss. Contents of the invention [0003] The invention provides a method and device for recovering and treating the tail gas of isobutyraldehyde, which not only can effectively recover and process the tail gas of isobutyraldehyde, prevent environmental pollution, but also prevent the tail gas from causing harm to the human body. [0004] The present invention adopts the following technical solutions: a device for recovering and treating the isobutyraldehyde tail gas of th...
