Description
Technical field
The present invention relates to Petro-Chemical Machinery New Equipment Engineering technology, particularly relate to disjunctor bearing and the annular-pipe reactor thereof of annular-pipe reactor of the special equipment of a kind of polypropylene for the field petrochemical industry, polyethylene production.
Background technology
Annular-pipe reactor is mainly as polypropylene and poly production equipment in the petrochemical industry, also is common in the production equipments such as mud cooler in the petrochemical industry, butylene cooler.
In the prior art, common annular-pipe reactor is looked its production capacity size and is included some straight connectors, chuck communicating pipe, elbow and tie-beam, and wherein, per two straight connectors are managed in the inner and are connected into successively one with two elbows and are communicated with runner.Because polymerisation can produce heat, so straight connector has its inner tube and outer tube forms the chuck runner, and the chuck communicating pipe that is connected with outer tube by being positioned at the elbow, the chuck runner is connected into one successively is communicated with runner.By the cooling medium in the chuck runner reaction heat is taken away.Also be provided with corrugated-type expansion joint, erection support and a beam seat on the outer tube of straight connector, tie-beam is connected with a beam seat by bolt, straight connector is connected be combined into space framework.This annular-pipe reactor is many foundation supports, and namely every straight connector all is provided with the erection support corresponding with it.
For example, the structure of 300,000 ton/years the polyacrylic annular-pipe reactor of production, as depicted in figs. 1 and 2, including six each long 50m of being, external diameters is straight connector R1, R2, R3, R4, R5, the R6 of 710 mm, and five 180 ° of large elbow A1, A2, A3, B1, B2,90 ° of elbow B3 that centre-to-centre spacing is 4200 mm, corresponding being connected in series and form a connection runner that circulation is whole successively, and by being positioned at five chuck communicating pipe C1, C2, C3, C4, the C5 that the elbow is connected with outer tube the chuck runner is connected into a connection runner successively; Cooling medium is entered by the cooling medium inflow entrance 2A of chuck runner, and to the cooling medium flow export 2F outflow of chuck runner, six erection support D1, D2, D3, D4, D5, D6 are positioned at the bottom of each straight connector R1, R2, R3, R4, R5, R6.The elbow, bottom of annular-pipe reactor is provided with axial-flow pump, reaction mass enters annular-pipe reactor by reaction mass inflow entrance 1A, under the driving of axial-flow pump, reaction mass stirs in straight connector, circulates, and under the effect of catalyst, after reacting the polypropylene that forms pulpous state, released by reaction mass flow export 1B again, then enter to granulating system; This annular-pipe reactor is seated on the high platform base of 11m, heavily about 210 tons of whole equipment.Wherein, erection support D1, the D2 that adopts, D3, D4, D5, D6 are circular erection support.To shown in the visual angle, straight connector R1 and R2 have independent erection support D1 and D2 as shown in Figure 2 such as the W among Fig. 1.
Scarcity along with petroleum resources, for adapting to market to great demand and the development of ethylene production special raw material, structure, production capacity, quality to loop reactor apparatus have all proposed new harsher requirement, require to take full advantage of resource to day by day improving in-depth on the refining of crude oil and the chemical process thereof, require an equipment can switch the product of producing the different trades mark, simultaneously, chemical enterprise is also expected to reduce cost by the scale effect of high production capacity, is improving in price the market competitiveness.At present, the production capacity of domestic separate unit Loop Reactor for Polypropylene is brought up to present 350,000 ton/years by 70,000 ton/years of first production domesticization in 1996.Although the patented technology of high energy double tube reactor has solved a lot of structure adaptability problems of traditional annular-pipe reactor, along with the further expansion of the size of capacity, still there are many parts that are worth transforming in present annular-pipe reactor structure:
(1) along with the increase of straight connector height, the lifting of towering slim-lined construction causes nonvolatil plastic deformation easily, needs the special hoisting tool of design, and need to reinforce straight connector, needed auxiliary work also increases, and has virtually increased the cost of manufacturing enterprise;
(2) along with the increase of straight connector height, the scene of towering slim-lined construction is installed crane is had higher requirement;
