Technical Field
The utility model relates to the technical field of cleaning equipment, in particular to a cleaning device for a vehicle urea tank.
Background
The oil vehicle tail gas denitration technology (SCR) is the denitration technology which is most widely applied in the next step, nitrogen oxides generated by a diesel engine can be effectively removed, and nitrogen oxides in the tail gas react with ammonia gas under the action of a surface catalyst to generate harmless nitrogen and water during working. Because ammonia gas is unstable and has safety risk, the reducing agent for denitration is gradually replaced by urea solution, and because urea can be decomposed and released under the condition of high temperature to participate in the denitration reaction, the diesel vehicle needs to store the urea solution in normal running, so that a urea tank is generated.
However, during long-term use of the urea tank, impurities are introduced during filling and urea solution is crystallized, scale is generated at the bottom or the inner wall of the urea tank, and the scale is likely to fall off to cause blockage of a urea injection pipeline, so that the urea tank for vehicles needs to be cleaned and maintained regularly, along with formal implementation of national sixth emission standard, the loading capacity of the urea tank is rapidly increased, most of the conventional urea tank is cleaned by adopting a direct flushing mode, for example, the urea crystallization tank for the vehicle, disclosed in the utility model patent with the Chinese patent publication number of CN206995914U, is welded with a blanking pipe through a central opening at the bottom of the crystallization tank, an overflow pipe is welded with a left opening at the left side of the crystallization tank, and a flushing pipe is welded with a structure at one side of the blanking pipe to clean the urea tank.
