The shell side heat exchanger tube of pipe 18 and the unit 5 of upper end first is spilt, spray line 18 can the intermittently or serially low circulation of spray temperature
Ammonium hydroxide, has cooling water Uniform Flow inside the heat exchanger tube 16 of first unit 5 in upper end, therefore, ammonia steam is in cyclic ammonia water
Under cooling effect with heat exchanger tube 16, the rapid condensation ammonium hydroxide in part, is converged, with cyclic ammonia water in 16 outer wall of heat exchanger tube successively
The heat exchanger tube 16 of lower floor is dripped to, from the part of appliance rinsed in the unit 5 of upper end first.Ammonium hydroxide after convergence continues downward
17 import of housing of second unit 7 is flowed to, second top of 7 housing of unit 17 sets liquid-distributing disk 15, use
In being uniformly distributed the ammonium hydroxide that flows down from the unit 5 of upper end first, the ammonium hydroxide after distribution continues drop and is set to second unit
Heat exchanger tube 16 inside standby 7 housings 17, since the cooling of the 16 internal flow cooling water of heat exchanger tube of second unit 7 is made
With the material that the unit 5 of upper end first transports coagulates for ammonia with separating beginning condensation, ammonia in the middle part of the mixture of ammonium hydroxide
Knot is slower, is attached to the ammonium salt that drop on heat exchanger tube 16 easily forms high concentration, and then produces crystallization, divides through liquid-distributing disk 15
The liquid to get off is flowed after cloth and washes away heat exchanger tube 16 in second 7 housing 17 of unit, from rinsing second unit 7
Interior part of appliance.Ammonium hydroxide and uncooled ammonia in second unit 7 collect follow-up afterflow by ammonium hydroxide outlet
To the inlet tube of the 3rd unit 8, uniformly divide again by the liquid-distributing disk 15 in the 3rd 8 housing 17 of unit
Cloth ammonium hydroxide, while under the cooling effect of heat exchanger tube 16, the further condensation of ammonia is realized, after becoming liquid due to gas condensation
Volume reduces, and hydraulic barrier 14 is set in the 3rd 8 housing 17 of unit, uncooled through the outside of heat exchanger tube 16 for improving
What the flow velocity of ammonia, augmentation of heat transfer, while hydraulic barrier 14 were provided with liquid-distributing disk 15 passes through passage --- concave indentation 14-
2nd, the arcuate indentation 14-1 for passing through circular hole 14-3 and baffling of heat exchanger tube 16, is used for realization the 3rd 8 housing 17 of unit
Interior ammonia condensation, since the baffling of hydraulic barrier 14 acts on, the 3rd unit 8 flows into for a central inlet, both sides
Outlet outflow, flows to the 9 ammonia entrance of unit of lower part the 4th, in the 4th 9 housing 17 of unit, ammonium hydroxide is in liquid
Distributing disc 15 is uniformly distributed under acting on, and from the crystal of 16 outer wall of flushing heat exchanging pipe, ammonia is under the condensation of heat exchanger tube 16
Coagulating liq, hydraulic barrier 14 strengthen ammonia flowing, improve heat-transfer effect, finally realize the condensation cooling procedure of ammonia, obtain
Qualified ammonium hydroxide product.
The cooling aqueous medium used of the present invention, enters from the cooling water inlet 10 of the 4th unit 9 in lower part
Device, countercurrently flows up, successively by 4 times journeys of the 4th 9 bobbin carriage of unit, the 4th 9 heat exchanger tube 16 of unit,
Journey, 4 times journeys of the 3rd 8 bobbin carriage of unit, the 3rd 8 heat exchanger tube the 16, the 3rd of unit on four 9 bobbin carriages 4 of unit
Journey, second 7 bobbin carriage of unit, 4 times journeys, second 7 heat exchanger tube of unit 16, second on a 8 bobbin carriage 4 of unit
Journey, upper end first 5 bobbin carriage of unit, 4 times journeys, 5 heat exchanger tube of unit, 16 and of upper end first on 7 bobbin carriage 4 of unit
Journey on 5 bobbin carriage 4 of the unit of upper end first, is discharged by cooling water outlet 3, realizes the reversed flow condensation cooling to ammonia.Meanwhile
Due to ammonia in condensation process there are the phase-state change that gas phase becomes liquid phase, volume reduces, therefore is tapered into using size
Heat exchanger tube and tube spacing, for augmentation of heat transfer lifting device performance.
To improve equipment performance, the present invention can close the ammonium hydroxide discharge of ammonium hydroxide outlet 11, the housing 17 of four units
Interior ammonia persistently condenses, and liquid level gradually rises ammonium hydroxide from bottom to top in the housing 17 of four units, adheres to crystallization
Heat exchanger tube 16 is completed to be immersed in ammonium hydroxide, dissolving except the ammonium salt that decrystallizes, realization device from rinsing, after flushed, ammonium hydroxide by
Outlet discharge.The present apparatus can utilize stand-by pump 12 by the ammonium hydroxide of the 4th unit 9 through circulation with intermittent or continuity
Ammonia water pipe 13, is delivered to progress ammonium hydroxide sprinkling in the spray line 18 of first unit 5 in upper end and rinses, strengthen from flushing except knot
Brilliant effect.
Described above is only the basic principle of the present invention, and not the present invention is imposed any restrictions, every right according to the present invention
