Spiral pipe jacket type axial reactor

Abstract

The invention discloses a spiral pipe jacket type axial reactor. The spiral pipe jacket type axial reactor is characterized in that an upper seal head and a lower seal head are respectively fixedly arranged at the top part and bottom part of a cylinder body; a spiral heat exchange pipe is distributed in the axial direction of the cylinder body; an upper flat pipe plate header is communicated withthe water drain end of the spiral heat exchange pipe, and a lower flat pipe plate header is communicated with the water intake end of the spiral heat exchange pipe; the upper flat pipe plate header iscommunicated with a water collecting box, and the lower flat pipe plate header is communicated with a water distribution box; the upper flat pipe plate header and the lower flat pipe plate header arerespectively supported at the upper part and lower part of the cylinder body; both ends of a center fixed cylinder are respectively fixedly arranged on the upper flat pipe plate header and the lowerflat pipe plate header; a water jacket inner plate is covered onto the spiral heat exchange pipe along the outer wall of the spiral heat exchange pipe; a water jacket space is formed between the waterjacket inner plate and the cylinder body and is used for water to flow. The spiral pipe jacket type axial reactor has the advantage that by adopting the water jacket and spiral heat exchange pipe combination scheme, the whole catalyst bed layer can be uniformly cooled without overtemperature coking.

Description

technical field [0001] The invention relates to a chemical reactor, in particular to a coil jacket type axial reactor. Background technique [0002] Existing hydrogenation reactors are generally tube-and-tube reactors or plate-type reactors, and tube-and-tube reactors are filled with catalysts inside the tubes and water outside the tubes. The tubing of the hydrogenation reactor is At present, the maximum production capacity of ethylene glycol that has been put into operation in the market is 100,000 tons, and the specification of the hydrogenation reactor reaches Due to incomplete elimination of thermal stress, high bed resistance, reactor leakage, the device is in a state of shutdown. The ethylene glycol units that have been put into operation in many places in the market have an actual single series of 50,000 tons of ethylene glycol production capacity, and two series of ethylene glycol hydrogenation reactions of 200,000 tons, four units h 催 = 6000 hydrogenation rea...
