Abstract
The utility model provides a vinyl chloride dehydration device. The vinyl chloride dehydration device comprises a stock solution tank and a separation tank connected with the stock solution tank, wherein a liquid drop multiplication fiber packing component and a separation special plate group type separation component are arranged in the separation tank, and a small cylinder body for stabilizing a two-phase interface and preventing a disperse phase formed by entraining material in a water phase from discharging is further arranged on the separation tank; and an anti-swirl baffle plate for stabilizing a flow field in the separation tank, reducing the entrainment in the discharged material and enhancing a separation effect is arranged in the separation tank. The separation way has the advantages of shortening the long retention time, reducing the entrainment in an outlet and realizing stable operation when working conditions are unstable.
Description
Technical field
The utility model relates to a kind of vinyl chloride dewater unit.
Background technology
In Production of PVC, to the water content requirement≤100ppm of raw material vinyl chloride.Water in the vinyl chloride contains water-soluble iron ion and acid, and the performance of vinyl chloride resin is had very big influence.The moisture of effective elimination vinyl chloride directly influences the downstream polymerization technique.
The existing difference mode that dewaters: (1) cyclone drying, increased power consumption, be operating as negative pressure, bring air easily into, influence safety, the dehydration precision is also not high enough; (2) solid caustic soda absorption process is prone to pile up and stops up the hole runner, and the post-processed expense is high.(3) molecular sieve adsorption uses when suitable water content is lower.Initial investment is high, and the later stage operating cost is lower, need influence vinyl chloride purity easily with nitrogen to the molecular sieve regular regeneration.(4) alternating temperature absorption method.Use two towers of parallel connection, on one side absorption, the method for regeneration on one side.(5) coalescence method.The coalescence method can be removed most free water, then can't divide and manages out for being dissolved in moisture in the vinyl chloride.The coalescence method can be removed to 80ppm in the data.Mention in the document under 25 ℃ but also have, the water that is dissolved in the vinyl chloride can reach 1100ppm, does not reach the requirement of 100ppm in the requirement.Except the dehydration precision is not high, because the autohemagglutination of vinyl chloride, also the easy blocking inner core causes and safeguards institute's trouble caused in the production.
The utility model content
The utility model problem to be solved is: big and separative efficiency is low to the equipment investment that exists in the above process employing method, the shortcoming that material consumption and energy consumption are big provides a kind of vinyl chloride dewater unit.This device is static equipment, and non-power consumption also need not regeneration, and certain water environment capacity is arranged.Separation accuracy reaches the requirement of 100ppm.
The utility model technical problem to be solved is able to solve through following technical scheme:
A kind of vinyl chloride dewater unit; It is characterized in that: comprise original fluid container and coupled knockout drum; Be provided with drop multiplication fiberfill assembly and separating plate group formula separation assembly in the knockout drum, also be provided with on the knockout drum and be used for stablizing two-phase interface, prevent that water from carrying the decentralized photo of material secretly and discharging little cylindrical shell; Be provided with in the said knockout drum and stablize the knockout drum flow field, reduce the anti-whirlpool baffle plate that separating effect was carried, strengthened in discharging secretly.
Offer material inlet on the described original fluid container, the original fluid container bottom offers the original fluid container sewage draining exit, and the top of knockout drum offers light phase export, the thermometer mouth of pipe, the safety valve mouth of pipe, and the little cylindrical shell of knockout drum bottom offers knockout drum sewage draining exit, heavy out.
Described original fluid container is provided with liquid distribution trough.
Be provided with rectifier in the described knockout drum.
Be provided with drop multiplication fiberfill assembly in the described knockout drum.
Be provided with separating plate group formula separation assembly in the described knockout drum.
Described knockout drum light phase export portion is provided with anti-whirlpool baffle plate.
Described knockout drum is provided with the liquid level gauge mouth.
A kind of vinyl chloride dewater unit of the utility model compared with prior art has following beneficial effect:
Drop multiplication filler separation assembly has the effect of minimum drop in the decentralized photo being doubled into big drop; Can main droplet interception and coalescence of carrying decentralized photo in mutually secretly be increased; Make mainly middle mutually fine drop decentralized photo particle diameter increase, improve the later separation component efficiency; Specific panel group formula separation assembly is to utilize shallow pond sedimentation principle, light (weight) phase decentralized photo constantly float (sinking) gathering be adsorbed on (descending) laminate following (on) surface, form bigger drop and leave the separation swash plate, thereby reach the separation of weight phase.Drop multiplication filler separation assembly and specific panel group formula separation assembly all have drop multiplication ability, and they can adsorb by decentralized photo, make the drop multiplication become big, thereby rapid subsidence are separated.The separate mode of two kinds of separation assemblies of this combination can effectively improve separation accuracy, increases operating flexibility, reduces equipment size.This phase separator is stronger to the adaptability of separating operating mode, when in medium, containing a certain amount of impurity, also can guarantee the long-play of equipment, and the maintenance rate is low.In the shortcoming that gets into specific panel group formula separation assembly skewness, feed distributor is set to liquid, improves the separative efficiency of plate group.Cause during to material outlet that the knockout drum flow field is unstable, anti-whirlpool baffle plate is set.This device can effectively cut down the consumption of energy and material consumption, moisture in the stable separation vinyl chloride.
