Detailed description of the invention
Below in conjunction with accompanying drawing, the detailed description of the invention of the present invention is described in detail.It should be appreciated that this place is retouched
The detailed description of the invention stated is merely to illustrate and explains the present invention, is not limited to the present invention.
In the present invention, in the case of illustrating on the contrary, the noun of locality that " top, the end " etc. is included in term only represents
This term orientation under normal service condition, or for being commonly called as of skilled artisan understands that, and be not construed as this term
Restriction.
The invention provides the grain-drying system of a kind of tail gas clean-up, as depicted in figs. 1 and 2, the paddy of this tail gas clean-up
Thing drying system includes main body 1 and the exhaust gas processing device of grain drying machine, and this exhaust gas processing device includes housing 2, housing 2
And it is connected by vent between the main body 1 of grain drying machine；Housing 2 be internally provided with baffle plate 3 with towards vent, gear
The top of plate 3 is provided with dust collecting board 4；The top of housing 2 is provided with exhaust equipment 6；Wherein, baffle plate 3 is along straight line side
To the waveform plate extended, the surface of described waveform plate is formed with the blind hole of multiple indent, and (blind hole can strengthen tail further
The contact area of gas and baffle plate 3 and time of contact, it also is able to be effectively reduced the kinetic energy of dust granules simultaneously, thus beneficially dirt
The sedimentation of angstrom granule).
The grain-drying system of above-mentioned tail gas clean-up arranges housing 2 by the junction of the main body 1 of grain drying machine,
Arranging baffle plate 3 in housing 2, this baffle plate 3 is with towards vent, then the tail gas that self-ventilation mouth is got rid of just rushes on baffle plate 3
Hitting (as shown in Figure 2), tail gas is after constantly contacting with baffle plate 3, and the dust granules in tail gas will settle, meanwhile,
Dust collecting board 4 also is able to sub barrier 3 and dust granules is settled to bottom, and finally, dust granules is through sedimentation
Tail gas will be discharged from the top of housing 2 by exhaust equipment 6.In the apparatus, baffle plate 3 is possible not only to dust collecting board 4
Reach to settle the effect of dust granules in tail gas, at the same time it can also be avoid the discharge of tail gas is caused resistance, and then improve corn
Drying effect.
In the present invention, the concrete shape of dust collecting board 4 can select in wide scope, can be straight plate, also
Can be sketch plate, but in order to improve the effect of settling of dust, it is preferable that dust collecting board 4 is curved slab, curved slab distance
The distance at the top of housing 2 is gradually lowered from top to bottom.Pass through domes, it is possible to effectively return rebounding from baffle plate 3
Dust granules settles downwards such that it is able to prevent the diffusion of dust.
Meanwhile, the tail gas discharged for the ease of self-ventilation mouth can contact with baffle plate 3 easily, it is preferable that dust
The top of collecting board 4, higher than the top of vent, thus avoids dust collecting board 4 and the eliminating of tail gas causes the feelings of resistance
The generation of condition.
On the basis of the above, in order to be more beneficial for the sedimentation of dust granules, it is preferable that dust collecting board 4 is arc
Shape plate, and the radian of arc is 50-80 °.

The contact area of shape wave unit and time of contact, on the other hand, it is contemplated that the resistance that tail gas is caused by waveform unit big
Little, it is preferable that the radian at the top of the waveform unit of waveform plate is 40-60 °..Such angle, both can ensure that
Tail gas and waveform unit have enough contacts area and time of contact, at the same time it can also be avoid waveform unit to tail gas
Cause excessive resistance.
In the present invention, although dust collecting board 4 and baffle plate 3 can reach dust granules sedimentation effect, but in order to
Improve the removal effect of dust granules further, meanwhile, in order to remove harmful gas (the corn anaerobic respiration generation that corn produces
CO), it is preferable that the top of the inside of housing 2 is provided with filter mechanism 5.Wherein, the solid shape of filter mechanism 5 can be
Select in wide scope, but in order to improve contact area and the time of contact of tail gas and filter mechanism 5 further, it is preferable that
Filter mechanism 5 is the S-shaped structure along vertical direction, and S-shaped structure includes upper and lower two-layer drainage screen, fills in two-layer drainage screen
