Abstract
The utility model discloses a blowback type lignite drying pipeline comprising a drying pipe, wherein a cola inlet pipe is arranged at the upper end of the drying pipe; blowing openings for introducing flue gas slantwise and upwards are formed on the two sides of the middle part of the drying pipe, respectively; and an exhaust pipe is further arranged on one side of the lower end of the drying pipe. High-temperature flue gas is reversely introduced into the drying pipe through the blowing openings to thoroughly dry dropping lignite. The dropping lignite can be more dispersed and the dropping speed thereof can be delayed through a cone-shaped scattering device; therefore, the mixing effect of the flue gas is further improved. Moreover, the lignite in the coal inlet pipe is pre-dried through an auxiliary drying pipe.
Description
Technical field
The utility model belongs to brown coal drying equipment, is specifically related to a kind of backwash formula brown coal drying pipeline.
Background technology
At present, common brown coal drying pipe is to adopt structure as shown in Figure 1, and these drying tube 10 upper end gas blow pipes 11, sidepiece are provided with oblique coal feeding pipe 21 down, and gas blow pipe 11 feeds high-temperature flue gas brown coal are carried out drying.But, because that flue gas direction and brown coal fall direction is consistent, cause flue gas and brown coal undercompounding, cause the brown coal drying effect undesirable, influence the burning use of brown coal.
The utility model content
The utility model technical problem to be solved provides a kind of backwash formula brown coal drying pipeline, can make bottle coal mix fully, improves drying effect.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of backwash formula brown coal drying pipeline comprises drying tube, is provided with coal feeding pipe in the upper end of said drying tube, has the inflatable mouth that supplies flue gas to feed obliquely in the both sides, middle part of drying tube, and one side also is provided with blast pipe in the lower end of drying tube.
The inside, lower end of said drying tube also is provided with the solid and gas separator.
Said coal feeding pipe lower end also is provided with the taper device that is scattered.
Said coal feeding pipe middle part also is provided with the auxilliary pipe of the drying that supplies flue gas to feed.
Adopt technique scheme, this backwash formula brown coal drying pipeline comprises drying tube, is provided with coal feeding pipe in the upper end of drying tube, has the inflatable mouth that supplies flue gas to feed obliquely in the both sides, middle part of drying tube, and one side also is provided with blast pipe in the lower end of drying tube.Through inflatable mouth reverse feeding high-temperature flue gas in drying tube, the brown coal that fall are carried out abundant drying.Disperse and postpone falling speed more through the taper brown coal that device can cause to fall and break that are scattered, further improve mixed effect with flue gas.Carry out predrying through the auxilliary pipe of drying to the brown coal in the coal feeding pipe.
Description of drawings
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is elaborated:
Fig. 1 is the structure chart of traditional brown coal drying pipe.
Fig. 2 is the structure chart of the backwash formula brown coal drying pipeline of the utility model.
The specific embodiment
As shown in Figure 2, the backwash formula brown coal drying pipeline of the utility model equally also comprises a drying tube 20, is provided with coal feeding pipe 21 in the upper end of said drying tube 20, in order to the input brown coal.Different is, has the inflatable mouth 22 that supplies flue gas to feed obliquely in the both sides, middle part of drying tube 20, and a side also is provided with blast pipe 23 in the lower end of drying tube 20, and blast pipe 23 1 ends are and are tilted to.During use, in the input brown coal,, can fully mix with the brown coal that fall, to reach preferable drying effect through inflatable mouth 22 reverse feeding high-temperature flue gas in drying tube 20.As an embodiment, also be provided with solid and gas separator 24 in the inside, lower end of said drying tube 20, through the solids and gas mixture that falls is separated, make that the brown coal after separating continue to fall, flue gas is then discharged from the blast pipe 23 of a side.As another embodiment, also be provided with the taper device 25 that is scattered in said coal feeding pipe lower end, this taper device 25 that is scattered can disperse the brown coal that fall more, and postpones falling speed, thereby further improves the mixed effect with flue gas.In addition, the auxilliary pipe 26 of the drying that supplies flue gas to feed can be set also at said coal feeding pipe 21 middle parts, the brown coal in the coal feeding pipe are carried out predrying, thereby more help improving the drying effect of brown coal.Solid arrow among Fig. 2 is that brown coal flow to, and dotted arrow is a flue gas flow direction.
But; Those skilled in the art will recognize that; The above-mentioned specific embodiment is exemplary, is to be the restriction to this patent protection domain in order better to make those skilled in the art can understand this patent, can not to be interpreted as; So long as according to spirit that this patent discloses done anyly be equal to change or modify, all fall into the scope of this patent protection.
