Sizer and a second high pressure spray shower pipe are from top to bottom layered in casing, and two adjacent first high pressure spray shower pipes
Between be formed with rinsing area, two grades of atomization absorption areas, sizer and second are formed between the first high pressure spray shower pipe and sizer
One-level atomization absorption area is formed between high pressure spray shower pipe, the demister is in rinsing area, and several rinse sprays head is even
It is connected in the first high pressure spray shower pipe, several atomizing spray heads are connected in the second high pressure spray shower pipe, in the upper and lower ends of casing
Air outlet and air inlet are respectively equipped with, axial flow blower is connected at the air outlet of casing.
Further, the sizer includes filler plate and mounting rod, the fixation of several filler plates mutually across a certain distance
In on mounting rod.
Further, the filler plate is bellows-shaped, and barb plate washer is provided with filler plate.
Further, the barb plate washer is arc-shaped.
Further, several described atomizing spray heads are distributed on the upper and lower ends face of the second high pressure spray shower pipe.
Further, the rinse spray head is arranged on the lower surface of the first high pressure spray shower pipe.
Further, the bottom of the axial flow blower is provided with taper enlarging, and the taper enlarging is connected to the air outlet of casing
On.
The present invention has the advantages that：
1）Cabinet arrangement installs axial flow blower forced ventilation in granulation tower top, casing top, and one is to speed up gas flow rate, and two are
Reduce the vapour lock of sizer dry load and demister in casing, so that finished urea temperature is reduced under tower；
2）Demister in casing avoids atomization cleaning solution from taking out of outside tower and be splashed into tower, prevents secondary pollution and the shadow to production
Ring；
3）Arranged above and below atomizing spray head, added in sustained height and effectively absorb space and absorption number of times, it is ensured that assimilation effect.
Brief description of the drawings：
Fig. 1 is front view of the present invention.
Fig. 2 is top view of the present invention.
Fig. 3 is the structure chart of sizer in the present invention.
Embodiment：
The present invention is further illustrated below in conjunction with the accompanying drawings.
As shown in Figure 1 to Figure 3, a kind of dust collection box of the invention, including casing 1, axial flow blower 2, the first high-pressure spraying
Pipe 31, the second high pressure spray shower pipe 32, rinse spray first 41, atomizing spray first 42, demister 5 and sizer 6, two first high pressures
Shower 31, sizer 6 and a second high pressure spray shower pipe 32 are from top to bottom layered in casing 1, and adjacent two
Rinsing area 300 is formed between first high pressure spray shower pipe 31, two grades of mists are formed between the first high pressure spray shower pipe 31 and sizer 6
Change and be formed with one-level atomization absorption area 100 between uptake zone 200, the high pressure spray shower pipe 32 of sizer 6 and second, demister 5 is located at
In rinsing area 300, several rinse sprays first 41 are set in every first high pressure spray shower pipe 31, in the second high pressure spray shower pipe 32
Upper setting several atomizing sprays first 42, are respectively equipped with air outlet and air inlet, axial flow blower 2 connects in the upper and lower ends of casing 1
At the air outlet for being connected on casing 1.
Sizer 6 in the present invention includes filler plate 61 and mounting rod 62, and several filler plates 61 are mutually across a certain distance
It is fixed on mounting rod 62.Absorbing liquid is sprayed on filler plate 61 when in use, the particular type of the absorbing liquid is according to waste gas
Depending on specific composition.
Filler plate 61 is bellows-shaped, and barb plate washer 63 is provided with filler plate 61, what barb plate washer 63 can be increased
Absorption area can pin most of dust for failing to sponge and be flowed toward two grades of atomization absorption areas 200 again.Barb plate washer 63 is circle
Arcuation, convex structure can further pin dust increase absorption area.
Rinse spray first 41 in first high pressure spray shower pipe 31 is arranged on the lower surface of the first high pressure spray shower pipe 31.
Atomizing spray first 42 in second high pressure spray shower pipe 32 is evenly arranged in the upper and lower ends of the second high pressure spray shower pipe 32
On face.
Taper enlarging 21 is provided with the bottom of axial flow blower 2, the taper enlarging 21 is connected on the air outlet of casing 1.Cone
Shape enlarging 21 can increase fan inlet inspiratory capacity.
Dust collection box of the present invention is arranged in urea prilling tower top, and when in use, urea prilling tower includes carbamide dust
Lower end of the gas through casing 1 air inlet enter casing 1 in.Gas is first through one-level atomization absorption area 100, atomizing spray first 42
Bidirectional arrangements above and below in the second high pressure spray shower pipe 32, allow the water droplets sprayed out to form positive and negative two complete atomized liquids
Face；Gas enters behind one-level atomization absorption area 100 to be fully absorbed in sizer 6, and the filler plate 61 of sizer 6 is provided with barb
Plate washer 63, the absorption area not only increased but also can pin most of dust for failing to sponge and flowed toward two grades of atomization absorption areas 200
It is dynamic.
Gas enters behind two grades of atomization absorption areas 200, the rinse spray first 41 in the first high pressure spray shower pipe 31 of downside to
Lower sprinkling, the not absorbent dust in one-level atomization absorption area 100 is fully absorbed, gas enters back into demister 5, demister 5（Remove
Foam device 5 reaches more than 95% except more than 5 microns of water smoke rate）, gas finally by axial flow blower 2 will through absorb, row will be met after separation
Put and be vented outside the gas discharge tower of requirement, and water droplets can be locked in collection box, do not taken out of outside tower, it is to avoid band liquid is caused
Pollution.The first 42 periodic flushing demister 5 of atomizing spray in the second high pressure spray shower pipe 32 on top, has prevented a small amount of dust to be bonded at
On demister 5.
The structure ＆ working mechanism of demister 5 in the present invention is identical with demister structural principle of the prior art, therefore
Structure and principle of the present invention no longer to demister 5 are repeated.
Described above is only the preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, some improvement can also be made under the premise without departing from the principles of the invention, and these improvement also should be regarded as the present invention's
Protection domain.
