Description
1. technical field
The float-valve type gas-liquid-solid three-phase fluid bed reactor of circulation in provided by the invention having, the gas-liquid-solid three-phase fluid bed reactor architecture advances that belongs to.。
2. background technology
Gas-liquid-solid three-phase fluid bed reactor is known for a long time reactor, compare major advantage with fixed bed reaction and be its macroscopical mixability height, strong axle mixes mutually, help reaction power class hour can improving conversion ratio at complete mixing flow, can add in nothing and obtain the even temperature distribution under the measure condition, heat is introduced and is shifted out easily, temperature control is convenient, the particle inside diffusional resistance is little, liquid and solids external resistance to mass tranfer are low, catalyst is easy to change, be easy to maximize, in derived energy chemical, be mainly used in F-T and synthesize, dimethyl ether or methyl alcohol are synthetic, reactions such as floating bed hydrogenation.But existing three-phase fluid bed reactor, liquid-solid mixed phase enters distributor when improper shut-down, and liquid-solid separation takes place, and the solid phase fine powder is easy to deposition and stops up distributor; Rely on the settling section height of gravity higher, cause reactor too high, equipment investment increases greatly, especially high-pressure reactor; The bubbling shape is operation down, and gas speed is low, and the mass-and heat-transfer effect reduces relatively; After the heat-obtaining equipment attrition is destroyed, has only the emergency shutdown maintenance.
3. summary of the invention
The objective of the invention is to overcome the deficiency of existing gas-liquid-solid three-phase fluid bed reactor technology and provide and have the interior float-valve type gas-liquid-solid three-phase fluid bed reactor that circulates.
The present invention is made up of reactor, gas distributor, float-valve type nozzle, discharge gate, gas feed device, inner cyclone separator, two concentric tubes heat collector, inlet valve, outlet valve etc., it is characterized in that reactor top is provided with inner cyclone separator, two concentric tubes heat collectors are inserted at the top, and gas distributor is equipped with the float-valve type nozzle; The float-valve type nozzle be the spacing jet pipe of side-wall hole have one can be with the spacing float valve of air-flow size lifting; Every two concentric tubes are equipped with inlet valve and outlet valve.
4, description of drawings
Accompanying drawing Fig. 1 is the float-valve type gas-liquid-solid three-phase fluid bed reactor structural representation of circulation in having, and Fig. 2 is a float-valve type structure of nozzle schematic diagram.
The drawing of accompanying drawing is established bright as follows: 1. reactor, 2. gas feed device, 3. gas distribution grid, 4. float-valve type nozzle, 5. discharge gate, 6. inner cyclone separator, 7. pair concentric tubes heat collector, 8. inlet valve, 9. outlet valve, 10. spacing jet pipe, 11. spacing float valves, 12. exhaust outlets of side-wall hole
5. specific embodiment
Establish bright design feature of the present invention in detail below in conjunction with drawings and Examples.
Reactor (1) bottom is provided with gas feed device (2), is provided with gas distribution grid (3) near gas feed device (2) top; Gas distribution grid (3) central authorities are provided with blow-off valve (5), and float-valve type nozzle (4) is distributed on the gas distribution grid (3) by rounded projections arranged; Be provided with inner cyclone separator (6) at reactor (1) topmost, the dipleg of inner cyclone separator (6) extends to the top of gas distribution grid (3); Two concentric tubes heat collectors (7) are inserted at reactor (1) top, and every two concentric tubes of two concentric tubes heat collectors (7) are equipped with inlet valve (8) and outlet valve (9); Float-valve type nozzle (4) for the spacing jet pipe (10) of side-wall hole has one can be with the spacing float valve (11) of air-flow size lifting.
When the float-valve type gas-liquid-solid three-phase fluid bed reactor (1) of circulation is worked in having, after synthesis gas enters the preliminary distribution in reactor (1) bottom by gas feed device (2), flow through the float-valve type nozzle (4) of gas distribution grid (3), the spacing float valve (11) of float-valve type nozzle (4) is opened, sprayed into distribution grid at a high speed from the areole of spacing jet pipe (10) and contain the liquid phase of catalyst fines; Synthesis gas makes the liquid-solid phase generation fluidisation in the reactor, reacts under the effect of catalyst in liquid phase, emits or absorbs heat; Generation gas is carried the liquid that contains catalyst on a small quantity secretly and is entered inner cyclone separator (6) centrifugation, and the liquid that contains catalyst flow back in the liquid-solid phase of fluidisation attitude through inner cyclone separator (6), separates clean generation gas and enters the product recovery system by exhaust outlet (12); Cooling or heating agent enter two concentric tubes heat collectors (7) by the inlet valve (8) of two concentric tubes heat collectors (7), after pipetting or heat being provided, flow out pair concentric tubes heat collectors (7) by inlet valve (8) again; Because every two concentric tubes of two concentric tubes heat collectors (7) are equipped with inlet valve (8) and outlet valve (9), in ordinary production, if two concentric tubes generation wear and leakage wherein, only need close the inlet valve (8) and the outlet valve (9) of this root concentric tubes, just can guarantee to produce and normally carry out.
The float-valve type gas-liquid-solid three-phase fluid bed reactor of circulation utilizes the float-valve type nozzle can adjust gas distribution grid in provided by the present invention having, and reduces the pressure drop of distribution grid, prevents that gas distributor from stopping up; Utilize inner cyclone separator, reduced the height of reactor, solved the isolated returning charge problem that contains the liquid of catalyst fines; Utilize two concentric tubes heat collectors, solved the difficult problem that heat collector generation wear and leakage has only emergency shutdown to overhaul.
