Description
Technical field
This utility model belongs to fixed bed reactors field, is specifically related to a kind of fixed-bed catalytic temperature control reactor with header.
Background technology
Fixed bed reactors, also known as packed bed reactor, are that a kind of solid catalyst or solid reactant of being filled with is in order to realize the reactor of heterogeneous reaction process.Solids (solid catalyst or solid reactant) is generally in granular form (particle diameter 2～about 15mm) and is piled into the bed of certain altitude (or thickness), and bed transfixion, fluid is reacted by bed.Fixed bed reactors are mainly used in realizing gas-solid catalysis, such as ammonia convertor, sulfur dioxide contact oxidation device, hydrocarbon steam converting furnace etc..
Fixed bed reactors have three kinds of primitive forms: 1) axially heat-insulating fixed bed reactors fluid axially from upper and under flow through bed, bed with extraneous without heat exchange.2) radial adiabatic formula fixed bed reactors fluid radially flows through bed, can use centrifugal flow or centripetal flow, and bed is same extraneous without heat exchange.Radial reactor is compared with axial flow reactor, and the distance of fluid flowing is shorter, and cross section of fluid channel is long-pending relatively big, and the pressure drop of fluid is less.But the structure of radial reactor relatively axial flow reactor is complicated.Both the above form all belongs to adiabatic reactor, is applicable to reaction heat effect little, or response system can bear the occasion of the variations in temperature caused under adiabatic condition by reaction heat effect.3) calandria type fixed bed reactor is constituted (when using reaction tube by many reaction tubes or heat exchanger tube (caliber is generally between 25～50mm) parallel connection, arrange in reaction tube pipe and between catalyst, pipe, thermophore is set, when using heat exchanger tube, arrange in heat exchange tube and between thermophore, pipe, catalyst is set), reacting gas flows through catalyst and reacts, difference according to response type, thermophore carries out absorbing heat or generating heat, accelerate reaction rate, and therefore calandria type fixed bed reactor is applicable to the temperature control reaction that reaction heat effect is bigger.
In summary, when reaction heat effect is bigger (as, CO transformationreation and methanol-fueled CLC reaction), typically use calandria type fixed bed reactor, but the reaction tube of general calandria type fixed bed reactor or the most up to ten thousand of heat exchanger tube, how the pipeline of up to ten thousand is installed is fixed into for a problem, at present, the mounting means of calandria type fixed bed reactor is to use double flat tube plate to install, the installing hole coordinated with reaction tube or heat exchanger tube is set on flat tube plate, all reaction tubes or heat exchanger tube all pass two flat tube plates, flat tube plate serves location and the effect supported, but this mounting means there is problems in that 1) the flat tube plate function not collecting and cache, when using heat exchanger tube, thermophore is easily concentrated in outlet or import department and is poured in or gush out, it is unfavorable for import charging and the collection of outlet；2) flat tube plate takes up an area big, is fixed on the cylinder of reactor, when using heat exchanger tube, can hinder filling and the blowing of catalyst；3) when using heat exchanger tube, heat exchanger tube work can produce convergent-divergent stress, and in the most intensive plane concentrating flat tube plate of all of heat exchanger tube, the most all of convergent-divergent stress all can be concentrated in one plane, easily causes the mutual damage of flat tube plate and heat exchanger tube；4) when equipment needs to maximize, flat tube plate cost is the highest.
