Abstract
The utility model discloses a novel finned pipe type inertial separator, which is provided with a seamless steel pipe; the seamless steel pipe is longitudinal provided with fins or is provided with fins with hems, and the angles of the hems are 0 < = alpha < = 180DEG. The steel pipe between the fins is provided with a width L < 1 >, and the ratio of the width L < 1 > and the inner diameter d of the seamless steel tube equals to 0.5 - 1.5. The ratio of the width L < 2 > of the hems of the fins and the width L < 1 > of the width of the fins equals to 0.2 - 0.5. The seamless steel pipe is a superheater bank or a convection bank in a boiler.
Description
The utility model relates to separator, especially relates to novel finned tube formula inertia separator.
At present, recirculating fluidized bed obtains paying attention to day by day, and most of recirculating fluidized beds adopt cyclone separator, though have certain separating effect, drag losses is big, serious wear, thermal inertia is big, and these all are unfavorable for the maximization in pot Shanghai, in order to improve the defective of above-mentioned cyclone separator, domestic and international many research workers all study inertia separator, and the separator of being devoted to development of new is to replace cyclone separator.Pattern such as U-BEAM, the grooved pipe etc. of inertia separator commonly used, separative efficiency can satisfy under the certain condition, recirculating fluidized bed flying dust separation requirement; But when being used for high-temperature condition, material is had relatively high expectations, and when the separator height was higher, as not adopting specific process, then resolution element very easily was out of shape, and causes separative efficiency to descend.
The purpose of this utility model provides a kind of flying dust that integrates and separates and the novel finned tube formula inertia separator that conducts heat.
Be illustrated below in conjunction with accompanying drawing.
Fig. 1 is a novel finned tube formula inertia separator structural configuration schematic diagram;
Fig. 2 is no pin α=0 ° or 180 ° of fin tube type inertia separator schematic diagrames;
Fig. 3 is no pin α ≠ 0 ° of fin tube type inertia separator schematic diagram;
Fig. 4 has pin fin tube type inertia separator schematic diagram;
Fig. 5 adopts pottery, and refractory slab is the tubular type inertia separator schematic diagram of fin material.
The utlity model has seamless steel pipe 1, on seamless steel pipe, vertically be provided with fin 2, or be provided with the fin with flanging, its flanging angle 0≤α≤180 °. On steel pipe between fin, can be provided with abrasionproof pin 3. Fin width L1Equal 0.5～1.5 with the ratio of seamless steel pipe inner diameter d, fin flanging width L2With fin width L1Ratio equal 0.2～0.5. When some because of structural limitations Can not carry out the occasion of fin welding, as need to use the described fin tube type inertia separator of this patent when the old stove transformation time, can adopt temperature-resistant materials such as pottery, fire resisting plate to replace the common metal flat bar to become similar inertial separation structure. Said seamless steel pipe is overheated tube bank or the convection bank in the boiler. Fin material is common steel bar, pottery and fire resisting plate.
Principle of the present utility model is: when dust-contained airflow is restrained through separator, particle clashes into mutually with tube wall and separates on the one hand, on the other hand owing to be provided with the fin of band flanging, to between fin and flanging, form a mobile district that turns back, thereby change the gas-solid nowed forming, part particle is carried secretly by air-flow and is entered this zone and separatedly get off, and can improve separative efficiency greatly like this.The utlity model has the double action of augmentation of heat transfer and separating effect, and owing to have good cooling effect as the fin of the key element of inertial separation, thereby require low to the material of fin.In order to prevent wearing and tearing, some abrasionproof pins of can on heat-transfer pipe between fin, burn-oning.This utility model can be used for the middle temperature convection bank district in the CFBB, also can be used for high-temperature area, as is used in high-temperature area, because of heat transfer intraductal working medium temperature is lower, can plays cooling fins and unlikelyly makes fin overtemperature distortion.
Advantage of the present utility model: (1) separative efficiency height; (2) drag losses is low; (3) combine to realize separating with heating surface bank and be integrated in one with heat transfer; (4) simple in structure, arrange compact; (5) overcome the yielding defective of resolution element that more existing inertia separators bring because of maximization; (6) owing to fin and heating surface bank as resolution element are combined into one, solved the material problem of the independent resolution element that general inertia separator adopted, available common material replaces expensive exotic material.
