Description
Technical field
The utility model relates to a kind of fertilizer production equipment, specifically a kind of high tower compound fertilizer urea melting operation gas concentration unit.
Background technology
In high tower compound fertilizer production process, wherein a step need to be by urea melting, in urea melting process, need to absorb heat, and urea after melting needs to pass through cooling granulating after mixing with other raw materials again, so that follow-up production and processing, urea can produce the gas that contains a large amount of ammonias and carbon dioxide in melting process, and this gas discharging is understood major polluting atmosphere environment in air, affect the health of human body.Chinese patent 2012203886133 discloses a kind of " urea tail gas ammonia retracting device ", utilizes atomizer to spray vaporific absorbent, and utilizes horizontally disposed gas-liquid distributing disc to improve the contact area of tail gas and absorption liquid, improves tail gas absorption efficiency.This urea tail gas ammonia retracting device is compared conventional exhaust retracting device absorption efficiency and is increased, but because gas-liquid distributing disc is horizontal positioned, fluid-tight is thicker, and gas is larger by resistance, design and installation is had relatively high expectations, if gas-liquid distributing disc can not maintenance level, cannot play a role; The area of gas-liquid distributing disc is less simultaneously, and the efficiency that equipment operating efficiency and tail gas absorb all needs further to be improved.
Summary of the invention
The utility model provides a kind of simple in structure, convenient for installation and maintenance, high tower compound fertilizer urea melting operation gas concentration unit that absorption efficiency is high for addressing the above problem.
The utility model for the technical scheme that technical solution problem adopts is:
A kind of high tower compound fertilizer urea melting operation gas concentration unit described in the utility model comprises housing, is arranged on the atomizer in housing, the lower end of housing is fitted with air inlet pipe, the upper end of housing is provided with blast pipe, in the inner chamber of described housing with the dividing plate being obliquely installed, described air inlet pipe and blast pipe lay respectively at the both sides of dividing plate, the upper surface of described dividing plate, with the fin of many horizontally sets, is uniformly distributed multiple through holes on the dividing plate between adjacent two fins; The upper end fixed installation shower of dividing plate, described shower is communicated with the feed tube of atomizer by pipeline.
The lower surface of dividing plate is with the version that stops of horizontally set.
Described air inlet pipe is inserted on the base plate of housing, and the upper end of air inlet pipe is provided with tarpaulin, and the base plate of housing is provided with discharging tube.
Owing to having adopted said structure, this apparatus structure is simple, installation and maintenance is all very convenient, adopts atomization and two kinds of absorption patterns of liquid film, and absorption efficiency is high, to high tower compound fertilizer urea melting operation good tail gas purification effect.
Brief description of the drawings
Fig. 1 is the structural representation of an embodiment of the utility model.
Fig. 2 is the structural representation of dividing plate.
Detailed description of the invention
As shown in Figure 1, a kind of high tower compound fertilizer urea melting operation gas concentration unit described in the utility model comprises housing 1, is arranged on the atomizer 2 in housing 1, the lower end of housing 1 is fitted with air inlet pipe 3, the upper end of housing 1 is provided with blast pipe 4, in the inner chamber of described housing 1, with the dividing plate 5 being obliquely installed, the inner chamber of housing 1 is separated into the spray storehouse that is positioned at dividing plate 5 tops and the air inlet storehouse that is positioned at dividing plate 5 belows by dividing plate 5.Described air inlet pipe 3 and blast pipe 4 lay respectively at the both sides of dividing plate 5, and air inlet pipe 3 is positioned at air inlet storehouse, and blast pipe 4 is positioned at spray storehouse.Meanwhile, be positioned at and have better assimilation effect, described air inlet pipe 3 is inserted on the base plate of housing 1, and the upper end of air inlet pipe 3 is provided with tarpaulin 31, prevents that the absorption liquid of drippage from entering air inlet pipe 3, and the base plate of housing 1 is provided with discharging tube 6.The mouth of pipe of air inlet pipe 3, higher than the mouth of pipe of discharging tube 6, avoids absorption liquid to pour in down a chimney.
As shown in Figure 2, the upper surface of described dividing plate 5, with the fin 51 of many horizontally sets, is uniformly distributed multiple through holes 52 on the dividing plate 5 between adjacent two fins 51; The upper end fixed installation shower 53 of dividing plate 5, described shower 53 is communicated with the feed tube of atomizer 2 by pipeline.For making distribution of gas even, can also the lower surface of dividing plate 5 with horizontally set stop version 54.
The tail gas that high tower compound fertilizer urea melting operation produces enters in air inlet storehouse by air inlet pipe 3, under the effect that stops version 54, being divided into some layers enters above dividing plate 5 by through hole 52, and spray with shower 53 absorption liquid guttering down along dividing plate 5 upper surfaces and react, now, fin 51 on dividing plate 5 can stop flowing of absorption liquid, make it flow slowly and form liquid film on dividing plate 5, be conducive to the abundant absorption of tail gas.Remaining portion gas is atomized the vaporific absorption liquid absorption that shower nozzle 2 sprays in uphill process again, and reacted absorption liquid finally flows in air inlet storehouse by the through hole 52 of dividing plate 5 lower ends, and discharges from discharging tube 6.Clean air is discharged from blast pipe 4.
