Description
Technical field
The invention belongs to benzene tail gas recovery device field more particularly to a kind of benzene recyclable devices for the tail gas containing benzene.
Background technique
Benzene is colourless to faint yellow volatile liquid, has strong aroma taste.It is inflammable, it is toxic.5.53 DEG C of freezing point, boiling point
80.1℃.It is widely used as solvent, especially in the production of hazardous chemical.
The finishing operation of reaction mixture post-processing, is distilled off solvent benzol getting the product.To enable benzene by thoroughly
It removes, in the later period of distillation, needs to be passed through nitrogen in the product into distillation still and drive remaining benzene, benzene vapour is with nitrogen one
Outflow is played, tail gas containing benzene is formed.To prevent tail gas containing benzene from entering atmosphere, environment is polluted, it is necessary to condense to tail gas containing benzene cold
But, to recycle benzene therein.
Chinese patent CN204447662U for it is existing traditionally, recycle benzene device include condenser, benzene groove and
3 equipment of cold-trap, condenser and benzene groove are cooling using tap water, and cold-trap is cooling using the chilled brine of low temperature, tail gas containing benzene
Followed by condenser, benzene groove and cold-trap, wherein flow direction of the tail gas in cold-trap is upper entering and lower leaving, and the benzene being condensed stays in cold
In trap, benzene groove cannot be returned in time, in the actual operation process cold-trap clogging frequent occurrence, cause distillation cannot be just
Often carry out.The reason of causing cold-trap to block is: benzene is volatile, and the higher tap water of benzene groove temperature is cooling, inevitably has
Operative liquid benzene is volatized into cold-trap, cooling by the very low chilled brine deep condensation of temperature in cold-trap, when benzene is cooled to
It is just solidified at 5.53 DEG C or less, blocks cold-trap, and the benzene accumulated in cold-trap is more, blocked more serious.Once occurring
Cold-trap clogging, it is necessary to suspend distillation procedure, using electric heater or the method for hair drier heating cold-trap, keep solid-state benzene molten
Change, can just continue distillation procedure after cold-trap dredging.It operates time-consuming and laborious, and to lose a certain amount of benzene in operating process,
It is more seriously that benzene is inflammable and explosive, electric heating operation has security risk, discloses one kind and returns from tail gas containing benzene
The device for receiving benzene, by reducing benzene vapor and entering cold-trap, avoid benzene during condensing cooling benzene vapor recycling benzene
It is cooled excessively generation solidification in cold-trap and blocks cold-trap, ensure that operation successfully carries out, and reduces energy consumption, improve
The rate of recovery of benzene, effectively reduces benzene vapor and enters atmosphere and cause environmental pollution, for refuse reclamation and protection environment
Significant mode, overcoming and traditionally recycling the device of benzene includes 3 condenser, benzene groove and cold-trap equipment, condensation
Device and benzene groove are cooling using tap water, and cold-trap is cooling using the chilled brine of low temperature, and tail gas containing benzene is followed by condenser, benzene
Groove and cold-trap, wherein flow direction of the tail gas in cold-trap is upper entering and lower leaving, and the benzene being condensed stays in cold-trap, cannot be returned in time
Benzene groove is returned, in the actual operation process cold-trap clogging frequent occurrence, distillation is caused to cannot proceed normally.Cause cold-trap stifled
The reason of plug is: benzene is volatile, and the higher tap water of benzene groove temperature is cooling, inevitably has operative liquid benzene and is volatized into
Cold-trap, it is cooling by the very low chilled brine deep condensation of temperature in cold-trap, just occur when benzene is cooled to 5.53 DEG C or less
Solidification blocks cold-trap, and the benzene accumulated in cold-trap is more, blocks more serious.Once cold-trap clogging occurs, it is necessary to temporarily
Stop distillation procedure, using electric heater or the method for hair drier heating cold-trap, melts solid-state benzene, it just can be after after cold-trap dredging
Continuous distillation procedure.It operates time-consuming and laborious, and to lose a certain amount of benzene in operating process, be more seriously, benzene is inflammable easily
Quick-fried, there is security risk in electric heating operation, but since above-mentioned apparatus directly directly connects the benzene exhaust air handled well outward
Discharge, does not ensure that benzene exhaust air whether there is or not noxious material is contained, so as to cause exhaust emission environment, in addition, benzene in above-mentioned apparatus
It has a large amount of bubble in chilled brine deep condensation is cooling to generate, if do not poked bubble, so as to cause the recycling of benzene
It is impure, and the fixation benzene that benzene generates in chilled brine deep condensation is cooling is easy to be adhered to cold-trap inner wall, so as to cause
Benzene recycling is not thorough.
To sum up, needing to research and develop one kind at present can prevent exhaust emission environment, the benzene of recycling are pure, benzene recycling is thorough to use
In the benzene recyclable device of the tail gas containing benzene, come overcome in the prior art benzene recyclable device exhaust gas direct out emptying, to be easy dirt
Environment is contaminated, the recycling of benzene is not pure, benzene recycles halfway disadvantage.
Summary of the invention
The present invention in order to overcome in the prior art benzene recyclable device exhaust gas direct out emptying, thus be easy pollution environment,
The recycling of benzene is not pure, benzene recycles halfway disadvantage, can prevent from giving up the technical problem to be solved in the present invention is to provide one kind
Gas pollutes the benzene recyclable device that environment, the benzene of recycling are pure, benzene recycling is thoroughly used for the tail gas containing benzene.
