Description
Technical field
The present invention relates to a kind of chemical reactor more particularly to a kind of coil jacket formula axial flow reactors.
Background technology
Existing hydrogenation reactor is generally shell and tube reactor or plate-type reactor, and shell and tube reactor manages interior filling
Outer catalyst, pipe are water.The tubulation of hydrogenation reactor isThe maximum production to have put into operation on the market at present
Can be 100,000 tons of ethylene glycol, hydrogenation reactor specification is accomplishedSpecification, because thermal stress eliminate it is not thorough
Bottom, bed resistance is high, and reactor leakage, device is in end-of-life state.The ethylene glycol dress that many places are put into operation on the market
It sets, practical monosystem is classified as 50,000 tons of ethylene glycol production capacity, and the hydrogenation reaction of 200,000 tons of ethylene glycol uses two series, fourHIt urges=6000 hydrogenation reactor parallel running, that there are Catalyst packings is few, big, energy consumption of moving thermal energy force difference, resistance
High, the defects of side reaction object is more, device is difficult to amplify;Leak water in the plate of board-like hydrogenation reactor, plate outer loading catalyst, gas
For full Radial Flow, it can theoretically meet device enlargement glycol unit, being not suitable for hydrogenation reaction on Practical Project uses.
It is reacted since with ethylene glycol carburetting can occur for ethyl alcohol, if bed overtemperature occurs and is easy to form coking.
It is enclosed by the cuboid plate of several 150~400 (plate is wide) × H (plate is high) when the heat exchange element of board-like hydrogenation reactor
At periphery, this periphery is really one polygonal, and it is even that catalyst will appear became uneven, is easy to happen catalyst bed
There is coking phenomenon in hot-spot, has no idea to put into actual operation.
Existing oxonation device is generally shell and tube reactor or plate-type reactor, and shell and tube reactor manages interior filling
Outer catalyst, pipe are water.The tubulation of oxonation device isThe maximum production to have put into operation on the market at present
Can be 100,000 tons of ethylene glycol, oxonation device specification is accomplishedSpecification, because thermal stress elimination be not thorough,
Bed resistance is high, and reactor leakage, device is in end-of-life state.The glycol unit that many places are put into operation on the market,
Practical monosystem is classified as 50,000 tons of ethylene glycol production capacity, and the oxonation of 200,000 tons of ethylene glycol uses two series, four
HIt urges=6000 oxonation device parallel running, few, shifting thermal energy force difference that there are Catalyst packings, resistance is big, high energy consumption, is easy hair
Raw decomposition explosion, the defects of side reaction object is more, tube sheet is easily burnt, device is difficult to amplify;
It is enclosed by the cuboid plate of several 150~400 (plate is wide) × H (plate is high) when the heat exchange element of board-like oxonation device
At periphery, this periphery is really one polygonal, and it is even that catalyst will appear became uneven, is easy to happen catalyst bed
Hot-spot is not suitable for oxonation on Practical Project and uses, due to methyl nitrite begin at 140 DEG C thermal decomposition occurs it is anti-
It answers, methyl nitrite will occur to thermally decompose completely at 155~160 DEG C, and pyrolysis occurs to release heat big
(3216j/gCH3ONO), while being a volume increase reaction (2CH3ONO→CH3OH+CH2O+2NO), lead to temperature and pressure
It quickly increases, is bound to cause accident.
Existing methanol reactor is generally shell and tube reactor, plate-type reactor or the reaction of small tube sheet header tube beam formula
Device, shell and tube reactor, it is water that it is outer, which to manage interior loading catalyst, pipe,.The tubulation of methanol synthesis reactor isThe methanol that the maximum production capacity to have put into operation on the market at present is 400,000 tons, methanol synthesis reactor rule
Lattice are accomplishedSpecification, because thermal stress elimination is not thorough, bed resistance is high, reactor leakage, shell and tube first
Alcohol synthesis reaction device can not meet enlarged methanol synthesizer.The country is in the enlarged methanol device of operation, single series production capacity
It it is 60 or 900,000 tons, reactor is the board-like methanol synthesis reactors of Ka Sali or wears the small tube sheet header tube beam formula methanol-fueled CLC of dimension
Reactor, enlarged methanol reactor market are monopolized by foreign technology quotient.But it is anti-that the country introduces the board-like methanol-fueled CLCs of Ka Sali
Nine sets of device is answered, there are six sets of leakages (such as the Inner Mongol long the safe energy, Anhui Hua Yi, the new new energy in Inner Mongol), overhauls plate heat exchanger
Catalysis must be drawn off when element leak source, the repair time is at one month or more.The small tube sheet header tube beam formula methanol for wearing dimension closes
Ten sets or more are introduced at the reactor country, stringing difficulty is big, and the small side reaction object of heat exchange area is more, and catalyst bed overtemperature is (such as god
The methanol synthesis reactor of magnificent packet header methanol-to-olefins project), enlarged device is run using two more parallels, separate unit methanol
Synthesis reactor is difficult to realize enlargement.
