Description
Technical field
The utility model relates to a kind of rotary kiln, particularly relates to a kind of equipment for in-situ crystallization synthesis NaY molecular sieve.
Background technology
NaY molecular sieve can as excellent heavy-oil catalytic refinery catalyzer, and kaolin particle in-situ crystallization is the important step of production NaY molecular sieve.Current kaolin in-situ crystallization equipment adopts rotary kiln usually.Rotary kiln is the Thermal Equipment of a kind of calcining, roasting or drying granular and pulverulent material, is mainly used in calcination of cement clinker in Cement industry, also for refractory materials and the ceramic industry granular and pulverulent material of calcining and dry various raw material in above-mentioned industry.It is body of heater slow circumvolve that current rotary kiln is produced substantially, and material is added by higher tail end, is drawn off by lower burner end.Burner end sprays into fuel (coal dust, heavy oil or geseous fuel), and in stove combustion, flue gas is discharged by higher one end.This rotary kiln mode of production has a comparatively significantly shortcoming, and the temperature being exactly two ends is not too even, and internal temperature control comparatively not easily, even often can occur that head end temperature is too high burns out material phenomenon.And require comparatively strict for the kaolin in-situ crystallization maturing temperature of heavy-oil catalytic refinery catalyzer raw material.
Utility model content
The utility model is for the deficiency existing for prior art, and it is simple, reasonable in design to provide a kind of structure, during kaolin roasting, namely at roasting chamber's run duration, the temperature no matter each operating point needs is identical or different, and maturing temperature all can control a kind of equipment for in-situ crystallization synthesis NaY molecular sieve at the suitable temp needed.
To achieve these goals, the utility model provides a kind of equipment for in-situ crystallization synthesis NaY molecular sieve, comprising can the roasting chamber of turning motion, described roasting chamber arranged outside has closed confession hot cell, gap on the upside of described confession hot cell and between described roasting chamber is less than described for the gap on the downside of hot cell and between described roasting chamber, equally distributed electric heating device is provided with on the downside of described heat supply chamber interior, described confession hot cell lower inner part is also provided with the roller for lifting described roasting chamber, described roller is arranged in pairs, lift the both sides of described roasting chamber center of gravity line respectively.
Wherein, described roasting chamber comprises end section and stage casing, and described end section and junction, stage casing are set to profile of tooth respectively, are provided with thermal insulation material between described end section and the profile of tooth in stage casing.
The described two ends, hot cell that supply are provided with contraction section, and the junction in described roasting chamber end section and stage casing is positioned at the described contraction section for hot cell.
In production, generally do not need all electric heating device standard-sized sheets, if the temperature needed is higher, just open some electric heating devices more; If the temperature needed is lower, just opens some electric heating devices less, and temperature can be reduced by the power supply reducing each electric heating device.
The beneficial effect of this programme can be learnt according to describing of such scheme, structure is simple, reasonable in design, effectively can control the temperature of roasting chamber's each section from the beginning to the end, thus during kaolin roasting, namely at roasting chamber's run duration, the temperature no matter each operating point needs is identical or different, and maturing temperature all can control the suitable temp needed.Electric heating device is only arranged on the downside for hot cell, and one is be beneficial to equipment installation and maintenance, and two is that material generally all concentrates on the downside of roasting chamber.Roller is set in pairs, effectively can controls the sinuousness in stage casing, roasting chamber.Roasting chamber comprises end section and junction, stage casing is set to profile of tooth respectively, and be provided with thermal insulation material between end section and the profile of tooth in stage casing, the high temperature in stage casing can be avoided to be delivered to end, and one is avoid wasting energy, and two is improve production safety.Two ends, hot cell are provided with contraction section, and the junction in roasting chamber's end section and stage casing is positioned at the contraction section for hot cell, is also in order to avoid high temperature is delivered to for beyond hot cell.
