Abstract
The invention relates to a polyacrylamide colloid dry production line, which comprises a first air inlet pipe, a first air inlet large blower, a first air inlet small blower, a first dryer, a second air inlet pipe, a second air inlet large blower, a second air inlet small blower, a second dryer and an air return pipe, wherein the first air inlet large blower and the first air inlet small blower are sequentially set on the first air inlet pipe; air inlet of the first air inlet pipe is communicated with the first dryer; the second air inlet large blower and the second air inlet small blower are set on the second air inlet pipe; air inlet of the second air inlet pipe is communicated with the second dryer; the second dryer is connected to the first air inlet pipe through returned air of the air return pipe; and discharged material of the first dryer is connected to a chimney. According to the invention, the structure is simple; air volume needed to be dried and energy consumption are reduced; and the drying condition and the time of staying of the material are easily adjusted and controlled, thus the final product quality is ensured.
Description
Technical field
The present invention relates to a kind of drying device, is a kind of polyacrylamide colloid drying production line specifically.
Background technology
It is take acrylamide aqueous solution as raw material that polyacrylamide is produced, and under the effect of initator, carries out polymerisation, has reacted the polyacrylamide blob of viscose of rear generation through cutting, granulation, drying, pulverizing, final obtained polyacrylamide amine product.The drying of polyacrylamide, should evaporate a large amount of moisture, and controlling temperature of charge again can not be too high, also will prevent hot-spot simultaneously, so drying machine efficient and energy-conservationly just seem particularly outstanding.Tradition adopts vibration fluidized bed drying machine, and dry to polyacrylamide by drying medium, drying medium directly discharges, thermal waste, is unfavorable for energy-saving and emission-reduction.
Summary of the invention
For above-mentioned deficiency of the prior art, the invention provides a kind of structure simple, reduce required dry air quantity and energy consumption, the drying condition of material, the time of staying are easy to adjustment and control, and ensure the polyacrylamide colloid drying production line of end product quality.
The technical solution used in the present invention is: a kind of polyacrylamide colloid drying production line, comprise the first blast pipe, the large blower fan of the first air intake, the little blower fan of the first air intake, the first drier, the second blast pipe, the large blower fan of the second air intake, the little blower fan of the second air intake, the second drier and backwind tube, the large blower fan of described first air intake and the little blower fan of the first air intake are set in turn on the first blast pipe, and the first blast pipe air inlet is communicated with the first drier; The large blower fan of described second air intake and the little blower fan of the second air intake are arranged on the second blast pipe, and the second blast pipe air inlet is communicated with the second drier, and the second drier connects the first blast pipe through backwind tube return-air, and the first drier discharging connects the second drier.
Adopt technique scheme, the invention has the beneficial effects as follows:
1, first, the little blower fan ignition of two air intakes adds hot-air, hot-air sends into first, two driers, drying is carried out to the polyacrylamide particle in drier, dried hot-air in second drier is by backwind tube loopback first blast pipe, reclaim the heat of hot-air in the second drier, for improving the intake air temperature of the first blast pipe, reduce neat gas burner energy consumption, simultaneously also can combustion-supporting first neat gas burner by the steam in the hot-air reclaimed in the second drier, improve efficiency of combustion, further reduction neat gas burner energy consumption, play energy-saving and emission-reduction effect.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
In figure: the first blast pipe 1, first air intake blower fan 2, first neat gas burner 3, first drier 4, second blast pipe 5, second air intake blower fan 6, second neat gas burner 7, second drier 8, backwind tube 9.
Detailed description of the invention
Below in conjunction with drawings and Examples, the invention will be further described.
Shown in Fig. 1: a kind of polyacrylamide colloid drying production line comprises the first blast pipe 1, first air intake large blower fan 2, first air intake little blower fan 3, first drier 4, second blast pipe 5, second air intake large blower fan 6, second air intake little blower fan 7, second drier 8 and backwind tube 9, first air intake blower fan 2 and the first neat gas burner 3 are set in turn on the first blast pipe 1, and the first blast pipe 1 air inlet is communicated with the first drier 4; Second air intake blower fan 6 and the second neat gas burner 7 are arranged on the second blast pipe 5, and the second blast pipe 5 air inlet is communicated with the second drier 8, second drier 8 and connects the first blast pipe 1, first drier 4 discharging through backwind tube 9 return-air and connect the second drier 8.
