Technical field

The present invention relates to exhaust apparatus, and in particular to a kind of reactor blowdown vessel.

Background technique

EVA has extensive purposes, and there is application in the fields such as foaming shoe material, wire and cable, toy even space flight, aviation. In EVA bulk polymerization complexes, no matter either uses super-pressure tank reactor or use super-pressure tubular reactor It is that the pressure of which kind of inside reactor has all reached 200MPa or more, temperature is up to 200~400 DEG C.Blowdown vessel is exactly in parking Before, for discharging the polymerization gas in reactor and reaching the equipment of pressure release purpose.This equipment relies primarily on import in China.This Invention is the novel device of our company's independent research, is successfully applied to super-pressure and releases, and reaches the first water inlet of same kind of products at abroad It is flat.

Summary of the invention

The present invention proposes a kind of reactor blowdown vessel.

Technical solution of the present invention:

A kind of reactor blowdown vessel, it includes blowdown vessel ontology；The blowdown vessel ontology includes cylinder and is arranged under cylinder There are several polymerization gas imports, fixed peace in cylinder in upper cover, the lower head at end, cylinder lower part along cylinder outer peripheral surface is tangentially-arranged Equipped with spiral stream guidance device, spiral stream guidance device is located above polymerization gas import, and from circular motion, gradually transition becomes axis to guidance air-flow To movement；The reactor blowdown vessel further includes chimney, and chimney is fixedly mounted on upper cover, is upwardly extended.

The super-pressure polymerization gas of reactor discharge is entered in blowdown vessel, pressure release guides discharge gas by chimney then up Atmosphere is discharged into after body to height appropriate；The design of chimney plays the role of reduction barometric gradient, reduces vibration.It is considered that poly- It closes gas and is in high temperature and superelevation pressure condition in reactor before discharge, sharply decline in the instantaneous pressure for entering blowdown vessel, Flow velocity steeply rises, and forms very big vibration and impact, and temperature decline is relatively slow, thus will cause temperature in tank it is very high, Pressure difference is very big；The application, using the polymerization port of tangential in design, so that polymerization autogenous cutting generates circular motion to entering in cylinder Air-flow, the air-flow of circular motion rises, and gradually transition becomes to be axially moved under the guidance of spiral stream guidance device, in this way, high speed gas Physical efficiency keeps relatively stable flow regime, to inhibit air-flow confusion to reduce vibration, to solve the above problems；Circumference simultaneously The air-flow of movement will not cause vertical impact to barrel, play the role of alleviating vibration.

Further, the polymerization gas import is at double circumference uniform distribution, so that load is uniformly distributed symmetrical, further avoids gas Stream, which is flung, hits barrel, alleviates vibration.

Further, the spiral stream guidance device is a helicoid, and helicoid connect with cylinder inboard wall, lead and helical angle by Under supreme be stepped up.

Further, the upper cover is conical head；Avoid the impact of bleed stream and disorderly due to flow section generates mutation Disorderly, it is allowed to more stable, to reduce vibration.

Further, if being provided with dry saturated steam inlet on the upper cover；It is respectively arranged on the chimney and lower head Pipe by steam；In order to preheat before discharge to exhaust system, it is unlikely to violent substantially in discharge initial stage Metal Production The heating of degree and cause blowdown vessel to rupture.

Further, the lower head is conical head, and bottom is provided with manhole；After discharge, removing is being arranged Let off the coagulation that journey is gathered.

Further, the chimney periphery is provided with wind-resisting helical vibration circle；It is preferred that wind-resisting helical vibration circle is arranged in chimney top In 6 meters of length；For clearing up the air-flow vortex (also referred to as " Karman vortex street ") generated under high wind conditions in the leeward side of chimney； The frequency of this air-flow vortex will generate violent resonance when close with the intrinsic frequency of chimney, eventually lead to equipment fatigue damage It is bad.

Further, the reactor blowdown vessel further includes ring support, and ring support is sleeved on cylinder lower part；It is used to support entire discharge Tank.

It is an advantage of the invention that design is rationally, it is skillfully constructed, can be used in the polymerization gas discharged in reactor and reach to let out Press purpose.
