Not only not environmentally, but also a large amount of waste is formd, is unfavorable for reducing production cost.Therefore how to efficiently use in production process and produced
Raw waste water is a urgent problem to be solved.
Summary of the invention
In view of the above defects of the prior art, the present invention provides one kind can efficiently use dehydrogenation of isobutane dress
The waste water generated in production process is set, pollution of the waste water to environment is reduced, can reduce the dehydrogenation of isobutane device of production cost
Waste water reclaiming device.
The present invention is achieved by the following technical solution: a kind of dehydrogenation of isobutane device waste water reclaiming device, special
Sign is: including molecular sieve tank, cooling tower, circulating water pool, the water inlet of the molecular sieve tank is filled by pipeline and dehydrogenation of isobutane
The reaction lime set pipeline connection set, the water outlet of the molecular sieve tank connects the water inlet of the cooling tower by pipeline, described
The water outlet of cooling tower connects the circulating water pool, the circulation of the circulating water pool connection dehydrogenation of isobutane device.
It further, is the oil and pollutant further effectively removed in water, water outlet and institute in the molecular sieve tank
It states and is also connected with cooler and membrane separator in turn on the pipeline between the water inlet of cooling tower.It, can be right by the way that cooler is arranged
It is cooled down into membrane separator water, guarantees the separative efficiency of membrane separator.
The present invention also provides a kind of iso-butane carried out using above-mentioned dehydrogenation of isobutane device waste water reclaiming device is de-
Hydrogen production device wastewater recycling process, it is characterized in that: the pH value in water treatment procedure is 3-5.
It further, is the oil and pollutant further effectively removed in water, water outlet and institute in the molecular sieve tank
It states and is also connected with cooler and membrane separator in turn on the pipeline between the water inlet of cooling tower.
Further, to improve UF membrane efficiency, the water inlet temperature of the membrane separator is 100-120 DEG C.
