One-level spray washing layer is respectively enterd by one-stage water wash circulating pump 12, the first threeway 33, the second threeway 34 and the 3rd threeway 35
14 and two grades of spray washing layers 15 in, one-stage water wash liquid is connect with the back flow of gas for containing carbamide dust by being vortexed shape shower nozzle and spraying
Touch, while in the presence of hydraulic pressure, striking filler ball surface, make filling ball that bounce and turbulent flow to occur, water lotion is filled out in lower floor
Pellet surface forms uniform liquid film, and liquid film has adsorbed the 30% carbamide powder for being centered around 50～100um in filling ball ambient gas
Dirt；
Step 4：Gas described in step 3 containing carbamide dust continuous from bottom to top by filling ball, one-stage water wash
Liquid continuously passes through filling ball, due to hydraulic pressure and the collective effect of air pressure, the of honeycomb rapids ball dust catcher device 3
The air bubble liquid-membrane that a layer height is 50～60mm is defined above one layer of filling ball, and the gas containing carbamide dust is broken through 55 after liquid film
～65% dust-laden granule is adsorbed, and final step water lotion acts on whereabouts in self gravitation, to lower floor's filler ball surface
Washed, except the dust of sub-cloud filling ball surface adsorption, then by the baffling sheet separation of one-level corrugated sheet flow guide bar 2,
Collect in the catch tray for falling into one-level liter QI-mass liquid device 1；
Step 5：The one-stage water wash liquid that one-level is risen in 1 catch tray of QI-mass liquid device is fallen into described in step 4, with liquid level
Increase, enter in primary cycle reservoir 10 from one-level liquid outlet 31, reach 7.0% when the concentration of one-stage water wash liquid～
The first valve 27 of 10 bottom of primary cycle reservoir when 8.0%, is opened, makes 7.0%～8.0% one-stage water wash liquid enter urine
Plain solution concentration unit 13 is reclaimed by subsequent production device；
Step 6：By rapid ball dust catcher device 3, one-level spray washing layer 14 and two grades of shower waters described in step 4
The gas containing carbamide dust for washing layer 15 is changed into band liquid gas, and band liquid gas enters 7 middle and upper part of urea dust recovery device housing
Necking region, 4.5～5.0m/s is increased to by 3.5 original～4.5m/s with liquid gas flow rate now；
Step 7：The band liquid gas in the necking region of 7 middle and upper part of urea dust recovery device housing is entered described in step 6
Enter two grades to rise in the liter gas passage of QI-mass liquid device 4, the droplet impact to two grades with big particle diameter in liquid gas rises QI-mass liquid dress
4 liter gas cap bottom is put, the drop for forming liquid film or bigger particle diameter falls, enter the circulation of one-stage water wash circulation fluid；Described pass through
After two grades rise QI-mass liquid device 4, have dropped 80%～85% with the dust content in liquid gas, with liquid in dust size distribution
Scope is 30～70um, and flow velocity is 4.5m/s～5.0m/s；
Step 8：Two grades of water lotions in secondary cycle reservoir 8 in the presence of two grades of water washing cycles pumps 9, by two grades
Circulation reservoir 8 by two grades of water washing cycles pumps 9 and the 5th threeway 38 respectively with three-level spray washing layer 16 and level Four shower water
Wash layer 17 to be connected, two grades of water lotions fill the droplet that shower nozzle is atomized into 20～80um, substantial amounts of droplet and step by solid vertebra
QI-mass liquid device 4 is risen by two grades described in rapid seven QI-mass liquid device is risen with the 30～70um particle diameters dust in liquid gas at two grades
4 tops collide and contact, and in the presence of surface tension of liquid and dust-charge, the dust of small particle is carried out by droplet
Parcel, it is the big drop of more than 100um then to grow up to particle diameter, falls into two grades and rise QI-mass liquid device in acting on for liquid deadweight
In 4 drip tray, secondary cycle reservoir 8 is entered by two grades of liquid outlets 32, when two grades in secondary cycle reservoir 8 are washed
The second valve 26 of 8 bottom of secondary cycle reservoir when the concentration of liquid reaches 4.0%～5.0%, is opened, 4.0%～5.0% is made
Two grades of water lotions enter primary cycle reservoirs 10, the fluid infusion as primary cycle reservoir is used；
Step 9：In secondary cycle reservoir described in step 88,4.0%～5.0% two grades of water lotions enter one-level
After circulation reservoir 10, pressure is that the carbamide waste stripping liquid of 0.70～0.80MPa enters secondary cycle liquid storage by liquid supplementation pipe 37
Use as two grades of water lotions in groove 8；In described carbamide waste stripping liquid, the proportion of urine is 0%, and temperature is 80～95 DEG C；
