Description
Technical field
The present invention relates to a kind of for the isobutylaldehyde tail gas recycle of storage tank and the method for process and device thereof.
Background technology
Tail gas at present in the air accumulator of storage isobutylaldehyde is often directly be discharged in air by breather valve, owing to containing isobutylaldehyde gas and nitrogen, so not only contaminated environment in tail gas, harmful, and material loss in 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, the tail gas of isobutylaldehyde not only can reclaim and process, preventing pollution environment by effectively, avoids tail gas to damage human body.
Present invention employs following technical scheme: a kind of for the isobutylaldehyde tail gas recycle of storage tank and the device of process, it comprises nitrogen pot, nitrogen air-valve, check valve, appendix I, appendix II, appendix III, retort and water tank, appendix I is between nitrogen pot and the storage tank top of storage isobutylaldehyde, nitrogen pot communicates with storage tank through appendix I, nitrogen air-valve is arranged on appendix I, appendix II is between storage tank and the retort that methanol solution is housed, storage tank is communicated with retort by appendix II, exhaust shower nozzle is provided with in one end that appendix II extend in retort, check valve is arranged on appendix II, appendix III is between the top and water tank of retort, retort is communicated with in water tank by appendix III, also filler is provided with at the top of retort, outlet is provided with in the bottom of retort.
Described check valve is set to one-way breather valve.
The invention also discloses a kind of for the isobutylaldehyde tail gas recycle of storage tank and the method for process, it comprises the following steps:
Step one, first the nitrogen in nitrogen pot is supplemented nitrogen in the storage tank that storage isobutylaldehyde given by nitrogen air-valve, the liquid level that nitrogen floats on isobutylaldehyde is formed nitrogen envelope, when the air pressure in storage tank is greater than the pressure of storage tank, the mist containing nitrogen and isobutylaldehyde tail gas in storage tank will overflow and enter into retort by one-way breather valve and adsorb, when the air pressure in storage tank is less than the pressure of storage tank, in storage tank, carry out benefit nitrogen, make the air pressure in storage tank reach pressure;
Step 2, the mist entered into containing nitrogen and isobutylaldehyde tail gas in retort is entered in the methanol solution in retort by exhaust shower nozzle, exhaust shower nozzle immerses in methanol solution completely, isobutylaldehyde tail gas in mist is dissolved by methanol solution absorption, is drained in water tank collects after remaining nitrogen floats by appendix III.
In step 2 of the present invention, the concentration of methanol solution is the methanol solution of 60%.When having the taste of isobutylaldehyde tail gas in step 2 of the present invention in water tank, the isobutylaldehyde tail gas adsorbed in 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 storage tank is effectively absorbed, dissolved, isobutylaldehyde exhaust emissions so just can be prevented in air, so not only preventing pollution environment, avoids tail gas to damage human body.The raw material that the present invention adopts is methyl alcohol, and the raw material adopted is all daily nontoxic raw material, and cost is low, 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.
