In preformed hole, two pieces of dividing plates at the 1/4 and 3/4 of ammonia storage tank axial length, then weld ammonia storage tank tank skin and fixation respectively
The position that dividing plate 5 contacts；Next the assembly of ammonia storage tank and stationary barrier is put into full-heated type SSCR modules and takes thermal
In shell 2, then it is welded and fixed dividing plate and takes the contact site of thermal shell；Then, the ammonia for installing two ammonia storage tanks goes out
Tracheae 6, ammonia escape pipe obtain the top side that interface is respectively positioned on ammonia storage tank, by two pipes in shell converge be an escape pipe, and from
Full-heated type SSCR modules take the preformed hole on the shell 2 of thermal to draw, then angle valve 7 is installed on escape pipe, use fluid sealant
Ammonia escape pipe 6 and full-heated type SSCR modules are taken the contact site of the shell 2 of thermal seal；Finally, will take outside thermal
The end plate welding of shell both sides is complete.
For convenience of dismounting, the fast interface male end 9 of exhaust aftertreatment device is with taking the fast interface female end 3 of thermal to use chi
The very little not isometrical Quick splicing pipe to match.Take thermal only to be moved when installing and take thermal, make its fast interface female end 3 with
Fast interface male end 9 on preprocessor is plugged in together, you can the fixed bracket for taking thermal saves on the big frame of vehicle
The process of mounting flange.
Full-enclosed heating is carried out to ammonia storage tank 1 using motor exhaust, tail gas delivery temperature is generally at 150 DEG C ~ 350 DEG C.
From the tail gas that exhaust aftertreatment device 8 is discharged via taking the fast interface female end 3 of thermal to take hot charging into full-heated type SSCR modules
In the shell 2 put, flow through ammonia storage tank 1 and full-heated type SSCR modules take region between the shell 2 of thermal, and from tail gas outlet
Mouth 4 is discharged, and then realizes that tail gas heats to the full-enclosed of ammonia storage tank, when the ammonia-storing material in ammonia storage tank reaches desorption temperature,
The ammonia discharged is exported by ammonia escape pipe and enters the next unit of system.During device normal use, angle valve, which is in, to be opened
State, when in device ammonia use up need change when, angle valve close.
The completion for being passed through and adsorbing of active gases ammonia is carried out by ammonia escape pipe 6.High-purity work can be used
Industry ammonia bottle, in the environment of natural shady and cool ventilation, by pressure-reducing valve and drying system, in 0.2 ~ 0.4MPa inlet pressure ranges
Interior slowly to carry out filling ammonia, it is 2 ~ 3h to fill the ammonia time；Weighed before and after ammonia fill and take ammonia device, the net quality for confirming to be filled with ammonia exists
In preset range, after ammonia is filled in completion, the valve of whole system is closed, it is ensured that is not revealed.
This device is applied to the light truck that engine displacement is 3L, and double tank full-heated type SSCR modules take thermal to install
In the rear side of SCR postprocessor.According to SCR postprocessor to NH3Demand is set between ammonia storage tank volume and continual mileage
Relation.For example, after the storage tank 100% that double tank total measurement (volume)s are 40L fills ammonia, can be with driving for the SCR system of 3L engines
12000-15000km。
