The utility model has the advantage of:
(1) the super-pressure polymerization gas ejected in reactor, enter in blowdown vessel from polymerization gas inlet pipe, then upwards air is entered from chimney, because polymerization gas is in high temperature and super-pressure state before discharge in reactor, decline at the instantaneous pressure entering blowdown vessel, and temperature declines relatively slow, just cause in blowdown vessel that pressure reduction is large, flow velocity is fast, form very large vibration and impact, top installing chimney is to reduce barometric gradient, reduce vibration, and enter air after emission gases is guided suitable height;
(2) venturi accelerator is set in the bottom of chimney, the flow velocity at accelerator place in chimney is accelerated, pressure reduces, before so just making venturi accelerator, the pressure reduction of runner increases, and the pressure reduction of runner reduces afterwards, thus just can suitably increase body wall thickness, and reduce the wall thickness of chimney more, thus the center of gravity of equipment is reduced, make it more reasonable, safer;
(3) the arranged outside steam pipe coil of chimney and conical head, the upper cover place of tank body is provided with steam injection mouth, all to carry out preheating to exhaust system before discharge, be unlikely in the violent significantly intensification of discharge initial stage Metal Production and cause blowdown vessel to break, breather pipe is for passing into air to chimney coil pipe top after a stoppage, makes condensed water in coil pipe after a stoppage can emptying;
(4) chimney first half outer circumference surface is provided with wind girder, its effect is the air flow swirl for producing at the leeward side of chimney under clearing up high wind conditions, also Karman vortex street is claimed, will violent resonance be produced when the frequency of this air flow swirl is close with the intrinsic frequency of chimney, finally cause equipment fatigue damage; The ring type bearing of the utility model design, has firm, antidetonation, easy-to-install feature;
(5) low head is designed to back taper, and is provided with quick opening manhole, is convenient to after discharge terminates, remove the coagulation gathered in discharge process.
