Background technology
Urea for vehicle is applicable to be furnished with the automobile-used SCR exhaust aftertreatment of SCR() car of system, truck, passenger vehicle and heavy non-rice habitats use diesel-engine vehicles, it is the consumable goods have to used in SCR technology, converts the harmful nitrogen oxide of diesel engine emissions to harmless steam and nitrogen together with SCR catalyst.Along with state IV discharge standard implements closing on of time, the big city such as domestic Beijing, Shenzhen, Shanghai has started state of enforcement IV standard in advance.Meanwhile, current domestic medium-heavy truck, passenger vehicle, public transit vehicle major part adopt SCR technology route to reach state IV discharge standard requirement, and therefore, the urea for vehicle solution needed for SCR system becomes the consumable goods being equal to diesel oil.
Existing urea manufactures urea for vehicle and all adopts granular urea to add dissolved in purified water purification technique, so has several drawback, and first cost increases, i.e. granular urea freight, carbamide packing material expense and add the labour cost of dissolving tank；Second is increase fusing urea time of staying in the process send pelletize, improves the growing amount of biuret, aldehydes and metal ion, processes to the later stage and add difficulty.
Summary of the invention
The invention aims to overcome drawbacks described above, it is provided that a kind of device adopting fusing urea solution directly to manufacture urea for vehicle.
For reaching above-mentioned purpose, the method that the present invention adopts is: a kind of device adopting fusing urea solution directly to manufacture urea for vehicle, including one section of vaporizer, flash evaporator and dissolvers；The bottom of one section of described vaporizer is provided with fusing urea solution inlet port, fusing urea solution inlet port is connected with fusing urea solution by inlet control valve and pipeline, the top of one section of vaporizer is provided with steam (vapor) outlet, one section of vaporizer be internally provided with concentration sensor, one section of vaporizer is additionally provided with fusing urea taphole, described fusing urea taphole controls valve by pipeline and first and is connected with the dissolvers import on dissolvers, the described fusing urea taphole being arranged on one section of vaporizer is connected with the fusing urea solution inlet port of flash evaporator also by pipeline；The fusing urea taphole of described flash evaporator controls valve by pipeline and second and is connected with the dissolvers import on dissolvers, is also equipped with concentration sensor in the inside of flash evaporator；Dissolvers is provided with dissolvers import, ultra-pure water import and urea liquid outlet, is additionally provided with agitator at dissolvers.
A kind of improve as of the present utility model, described inlet control valve, first control valve, second control valve and concentration sensor is all connected with PLC.
Beneficial effect:
Employing fusing urea solution of the present utility model directly manufactures the device of urea for vehicle and adds dissolved in purified water purification by fusing urea is sent directly into dissolvers after pretreatment, decrease production process, it is reduction cost, is conducive to the advantages such as later stage process, the quality of our product can be improved, greatly strengthen the competitiveness of product in market.
