Abstract
The utility model relates to a melamine tail gas processing device of coproduction ammonium nitrate, including triamine tail gas pipeline, characterized by, triamine tail gas pipeline connect the solution tank, and the solution tank passes through tail gas export pipeline connection neutralizer. The utility model discloses an impurity of ammonium nitrate production system can be brought into by effectual reduction triamine tail gas to the impurity that the washing was smugglied secretly in the tail gas, can effectively improve impurity content in the granule ammonium nitrate product to effectual granule ammonium nitrate caking and the pulverization phenomenon improved.
Description
Technical field：
The utility model is related to a kind of device for recovering tail gas, at a kind of melamine tail gas of coproduction ammonium nitrate
Reason device.
Background technology：
Triamine tail gas typically uses reuse after the separation of ammonia carbon, costly；It is also used for producing ammonium hydrogen carbonate, value of the product is relatively
Low.Company is used for producing ammonium nitrate, is worth higher.But it is because carrying impurity in tail gas, containing compositions such as liquid urine, catalyst, triamines, special
Be not open in triamine device, docking process, impurity content is higher, is difficult to all remove with mechanical filter mode, easily causes ammonium nitrate
Product carries color, the caking of weighting particles ammonium nitrate product and powder phenomenon-tion, has a strong impact on the quality of particle ammonium nitrate.
Utility model content：
For solving the deficiency in above-mentioned technical problem, the purpose of this utility model is, provides one kind can overcome above-mentioned
Defect can effectively absorb the processing meanss of the melamine tail gas of ammonium nitrate.
The melamine tail gas processing meanss of coproduction ammonium nitrate provided by the utility model, including triamine exhaust pipe,
Triamine exhaust pipe connects solution tank, and solution tank connects averager by offgas outlet pipeline.
Described triamine exhaust pipe enters in a section of solution tank and is provided with spray washing device.
The shower nozzle spray ammonium nitrate solution of described spray washing device.
Described solution tank crown center position is provided with dividing plate.
The beneficial effects of the utility model are：
By washing the impurity carried secretly in tail gas, can effectively reduce the impurity that triamine tail gas brings ammonium nitrate production system into,
Impurity content in particle ammonium nitrate product can be effectively improved, thus effectively improving particle ammonium nitrate caking and powder phenomenon-tion.
Brief description
Fig. 1 the utility model structural representation；
In figure：1st, spray washing device；2nd, triamine exhaust pipe；3rd, shower nozzle；4th, solution tank；5th, dividing plate；6th, offgas outlet
Pipeline.
Specific embodiment
The utility model includes triamine exhaust pipe, and triamine exhaust pipe 2 connects solution tank 4, and solution tank 4 is gone out by tail gas
Mouth pipeline 6 connects averager.Triamine exhaust pipe 2 enters in a section of solution tank 4 and is provided with spray washing device 1.Spray is washed
Wash the shower nozzle 3 spray ammonium nitrate solution of device 1.Solution tank 4 crown center position is provided with dividing plate.
The spray washing device 1 increasing before the enterprising ammonium nitrate device averager of triamine exhaust pipe 2, selects according to exhaust temperature
With the impurity in the ammonium nitrate solution spray washing tail gas of 85% (mass content), using the viscosity of liquid with wrap up in band effect, pass through
Gas-liquid is fully contacted, and the liquid in tail gas, solid impurity washs, purified after tail gas entrance particle ammonium nitrate production system.
Ammonium nitrate solution is supplied by outside, and ammonium nitrate solution is pumped into shower nozzle and sprayed by spray washing device.
One solution tank 4 is increased on the triamine exhaust pipe 2 before entering averager, and has installed spray washing device additional, spray
The pipeline drenching wash mill connects ammonium nitrate solution, and ammonium nitrate solution sprays from shower nozzle, carries out solution tank with triamine tail gas cocurrent, passes through
Change exhaust gas flow direction and solution tank dividing plate 5, the solution carried secretly in tail gas is separated.Tail gas after separating passes through offgas outlet
Pipeline 6 enters averager.
Above-mentioned case study on implementation is only for understanding the utility model example, and is not to the utility model embodiment party
The restriction of formula.To belonging to the obvious change that spirit of the present utility model amplified out or change still in the utility model
Protection domain in.
