Technical field
The utility model relates to the superhigh-purity reagent purification techniques, is specifically related to a kind of purifying plant of ultra-pure dehydrated alcohol.
Background technology
Superhigh-purity reagent is one of indispensable key basic chemical industry raw material during the electronic applications microfabrication is made, and is mainly used in cleaning and the etching of chip.Ultra-pure dehydrated alcohol is organic solvent, is mainly used in the rinsing process of semicon industry ultraviolet negative photoresist, can support the use with developer for negative photoresist.
Along with the development of electronic applications technology, to the also day by day raising of purity requirement of electronic chemical product.The ethyl alcohol purification method that generally adopts at present is: industrial alcohol is directly rectifying after potassium permanganate and sodium hydroxide pre-treatment, and employed device mainly comprises rectifying tower and micro-strainer, and the purity of aforesaid method is not high, yields poorly.Because molecular sieve can adsorb the first alcohol and water of trace in the ethanol, therefore in the multiplex pre-treatment before industrial alcohol is purified.In the prior art, the adsorber of filling molecular sieve needs in time to change, but original ethanol can not be emptied completely in the adsorber, causes the leakage of ethanol during dismounting, and operating environment is brought certain pollution.
The utility model content
The purpose of this utility model is to overcome the defective that exists in the prior art, provides that a kind of technical process is reasonable, product purity is high and purifying plant stable, that meet environmental requirement, ultra-pure dehydrated alcohol that production efficiency is high.
For achieving the above object, the technical solution of the utility model is: the purifying plant of ultra-pure dehydrated alcohol comprises the adsorber that is filled with molecular sieve that communicates with storage tank, the discharge port of described adsorber is connected by pipeline with the opening for feed of rectifying tower, be provided with discharge port at the bottom of cat head discharge port and the tower on the described rectifying tower, described cat head discharge port is connected with the opening for feed of condenser by pipeline, the discharge port of described condenser is connected with quality supervision tank, micro-strainer successively by pipeline, and the discharge port of described micro-strainer is connected with finished pot by pipeline.
Wherein, described molecular sieve is the 3A molecular sieve.
Wherein, be respectively arranged with emptying arm on the pipeline between pipeline between described storage tank and the adsorber and adsorber and the rectifying tower, be connected with respectively the first valve on pipeline between described storage tank and the emptying arm and the pipeline between emptying arm and the rectifying tower, be connected with respectively the second valve on the described emptying arm, be detachable being tightly connected between described pipeline and the described adsorber.
Wherein, microfiltration membrane aperture 0.05～0.10 μ m of described micro-strainer.
Wherein, be connected with pump between described quality supervision tank and the micro-strainer.
Advantage of the present utility model and beneficial effect are: this device technique flow process is reasonable, at the pipeline that connects molecular sieve opening for feed and discharge port emptying arm is set, make the more convenient environmental protection of replacing of adsorber, indirectly improved production efficiency, guaranteed simultaneously the purity of product;
By the timely detection to quality inspection tank product, be convenient to rectifying is derived the control of product, can avoid the phenomenon that quality there are differences between the resulting finished product of raw material of different batches different mass simultaneously, guarantee the stable of quality product.
