Background technology
Fixed fluidized-bed reactor is the reactor types that catalytic cracking and the exploitation of Deep Catalytic Cracking process new catalyst, technical study and feedstock optimization extensively adopt.Can be divided into three kinds of patterns by its reactor profile: the one, straight barrel-shape reactor is like U.S. Pat P 6,069,012 disclosed fixed fluidized-bed reactor; The 2nd, top is that cylindrical, bottom is obconic reactor, like Chinese patent CN 2512495Y and the disclosed fixed fluidized-bed reactor of CN 201042664Y; The 3rd, multistage reducing reactor is like Chinese patent CN 201064712Y, CN 2855524Y and the disclosed fixed fluidized-bed reactor of CN 201143427Y.Above-mentioned reactor is different with inner member because of its structure, can be respectively applied for the higher catalytic cracking reaction of conventional catalytic cracking reaction and temperature.Because test is less with the volume of fixed fluidized-bed reactor; Its catalyst and Oil-gas Separation generally adopt pottery or metal powder filter, and catalytic cracking reaction and catalysis are split the temperature of reaction up to more than 500 ℃, and contain more unsaturated hydro carbons in the product; So be prone to polymerization even coking take place at the hydrocarbon filter device outer wall place of reactor; Stop up the micropore of hydrocarbon filter device, cause reactor pressure to raise, what influence was tested normally carries out; Also make simultaneously some can't not carry out the reaction of higher temperature, remove reaction, limited the scope of application of this type reactor like catalytic pyrolysis through the fixed fluidized-bed reactor of particular design.
Summary of the invention
The utility model is the deficiency that exists to the existing fixed fluidized-bed reactor; A kind of coolant distribution device is provided; In order to reduce fixed fluidized bed settling section top reaction mass temperature, reach unsaturated hydro carbons generation polymerization in the inhibitory reaction material and stop up the purpose of hydrocarbon filter device.This coolant distribution device help the stopping reaction device pressure, improve the fluid effect of catalyst; Improve the success of the test rate, strengthen the adaptive capacity of common fixed fluidized-bed reactor catalytic cracking reaction with the different article raw materials of high temperature, high agent-oil ratio, high linear speed.
For realizing above-mentioned purpose; The technical scheme that the utility model adopts is: a kind of coolant distribution device is made up of inlet tube and distributor pipe two parts; Inlet tube and distributor pipe communicate, and distributor pipe is a hollow pipe, are uniformly distributed with some spray-hole or playpipes that are used to spray cooling medium on it.
Being shaped as the circular or helical form of individual pen or enclosing circular or dendroid more of described distributor pipe.
The spray-hole of described formation distributor pipe or the direction of playpipe are oblique below, with the angle of vertical direction be 10 °～80 °, preferred 30 °～60 °.
The diameter D of the hollow pipe of described formation distributor pipe with its on spray-hole or the aperture d ratio of playpipe be 3～25: 1, preferred 8～15: 1.
On the hollow pipe of said formation distributor pipe with spray-hole or the aperture of playpipe be 0.1～1.5mm, preferred 0.3～1.0mm.
Said formation distributor pipe the die pipe on the length L of playpipe be hollow pipe diameter D ratio be 0.3～1.0.
The utlity model has following beneficial effect: (1) is provided with the said cold gas distributor of the utility model on the settling section top of fixed fluidized-bed reactor; Can in course of reaction, spray into the inertia refrigerating gas to reactor top; High-temperature oil gas to settling section top is carried out forced cooling; The unsaturated component that reduces wherein is inclined at the lip-deep polymerization coking of hydrocarbon filter device, keeps the hydrocarbon filter device unobstructed; (2) can stopping reaction device internal pressure, improve the catalyst fluidization effect, guarantee test carries out smoothly; (3) can widen the adaptive capacity of fixed fluidized bed reaction pair different material, especially to the adaptive capacity of residual oil; (4) help improving reaction temperature, strengthen the adaptive capacity of common fixed fluidized-bed reactor, widen the range of application of fixed fluidized-bed reactor the catalytic cracking reaction of high temperature, high agent-oil ratio, high linear speed.

The specific embodiment
Below in conjunction with accompanying drawing the utility model is done more detailed explanation, its purpose is to explain better the content of the utility model, but the restriction of the example that the protection domain of the utility model does not receive to be lifted.
As shown in Figure 1, a kind of coolant distribution device is made up of inlet tube 1 and distributor pipe 2 two parts, and inlet tube one end is positioned at the fixed fluidized-bed reactor outside, and the other end stretches into fixed fluidized-bed reactor settling section top and communicates with distributor pipe.Distributor pipe 2 is a hollow pipe, and its profile is individual pen circular (like accompanying drawing 2a), helical form (like accompanying drawing 2b), enclose circular (like accompanying drawing 2c) or dendroid (like accompanying drawing 2d) more.Be uniformly distributed with some spray-holes 3 (like accompanying drawing 3a) that are used to spray cooling medium on the hollow pipe of composition distributor pipe 2, more even in order to make coolant distribution, spray-hole 3 can be designed to playpipe 4 structures (like accompanying drawing 3b).The hollow pipe two ends of said distributor pipe are non-closed shape, with the end sealing of hollow pipe away from inlet tube.The aperture d of described spray-hole 3 or playpipe 4 is 0.1～1.5mm, preferred 0.3～1.0mm, its direction is oblique below, with the angle of vertical direction be 10 °～80 °, preferred 30 °～60 °, can prevent that like this catalyst fines from directly getting in the distributor pipe.The diameter D of hollow pipe is 3～25: 1 with the ratio of the aperture d of spray-hole 3 or playpipe 4, preferred 8～15: 1.The length L of playpipe 4 be hollow pipe diameter D ratio 0.3～1.0.
