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).

Technical field
The present invention relates to a kind of for the isobutylaldehyde tail gas recycle of storage tank and method and the device thereof of processing.
Background technology
Tail gas in the air accumulator of storage isobutylaldehyde often is directly to be discharged in the air by breather valve at present, owing to contain isobutylaldehyde gas and nitrogen in the tail gas, so not only contaminated environment is harmful, and the material loss in the storage tank is high.
Summary of the invention
The invention provides a kind of recovery for isobutylaldehyde tail gas and processing method and device thereof, it not only can reclaim the tail gas of isobutylaldehyde and process effectively, prevents contaminated environment, avoids tail gas that human body is damaged.
The present invention has adopted following technical scheme: a kind of for the isobutylaldehyde tail gas recycle of storage tank and the device of processing, it comprises nitrogen pot, the nitrogen air-valve, check valve, the appendix I, the appendix II, the appendix III, retort and water tank, the appendix I is between the storage tank top of nitrogen pot and storage isobutylaldehyde, nitrogen pot communicates with storage tank through the appendix I, the nitrogen air-valve is arranged on the appendix I, the appendix II is at storage tank and be equipped with between the retort of methanol solution, storage tank communicates with retort by the appendix II, an end that extend in the retort in the appendix II is provided with the exhaust shower nozzle, check valve is arranged on the appendix II, the appendix III is between the top and water tank of retort, retort communicates by in appendix III and the water tank, top in retort also is provided with filler, is provided with outlet in the bottom of retort.
Described check valve is set to one-way breather valve.
The invention also discloses a kind of isobutylaldehyde tail gas recycle for storage tank and the method for processing, it may further comprise the steps:
Step 1, at first the nitrogen in the nitrogen pot is given through the nitrogen air-valve and replenished nitrogen in the storage tank of storing isobutylaldehyde, nitrogen floats on and forms the nitrogen envelope on the liquid level of isobutylaldehyde, when the air pressure in the storage tank during greater than the pressure of storage tank, the mist that contains nitrogen and isobutylaldehyde tail gas in the storage tank will overflow and enter into retort by one-way breather valve and adsorb, when the air pressure in the storage tank during less than the pressure of storage tank, mend nitrogen in the storage tank, make the air pressure in the storage tank reach pressure;
The concentration of methanol solution is 60% methanol solution in the step 2 of the present invention.When in the step 2 of the present invention the taste of isobutylaldehyde tail gas being arranged in the water tank, the isobutylaldehyde tail gas that adsorbs in the methanol solution is saturated, and at this moment methanol solution needs to change.
The present invention has following beneficial effect: after adopting above technical scheme, the present invention can utilize methanol solution that the tail gas in the storage tank is effectively absorbed, dissolves, so just can prevent that the isobutylaldehyde exhaust emissions is in air, so not only prevent contaminated environment, avoid tail gas that human body is damaged.The raw material that the present invention adopts is methyl alcohol, and the raw material that adopts all is daily nontoxic raw material, and cost is low, and is little to the injury of human body.Check valve of the present invention adopts one-way breather valve, and it can regulate conveying gas effectively.
