Abstract
The utility model discloses a heating device for a urea pipeline of a diesel engine, which comprises a urea pipeline body, wherein the outer surface of the urea pipeline body is wound with an electrical heating element, the outer surface of which is provided with an insulating layer; and a metal mesh layer is arranged between the outer surface of the pipeline body and the electrical heating element. By being matched with a urea solution control unit, the heating device conducts heating after the engine is started so as to heat evenly, and can stop heating when the temperature is increased to be minus 5 DEG C, and has simple, convenient and accurate control and short heating time. The urea solution in the pipeline can melt completely in cold areas (minus 30 DEG C) within about 23 minutes.
Description
Technical field
The utility model relates to a kind of diesel urea pipeline heating equipment.
Background technique
Use urea liquid as reactant based on the SCR diesel engine; in order to reduce discharging; and since urea liquid under normal environmental pressure; can solidify in the time of-11 ℃, freeze; for guaranteeing that diesel engine can normally use in cold season; must be to the urea pipe heat treated, to guarantee the urea liquid proper flow.Existing urea pipe heating equipment mostly is and utilizes engine cooling water to heat, common way is that cooling water pipeline and urea pipe are fitted tightly, its shortcoming is: under cold conditions, engine cooling water itself is heated to sufficient temp (more than 50 ℃) needs certain hour (general more than ten minutes), engine cooling water also will be to warm braw and urea box heating simultaneously, therefore to get heat limited for urea pipe, heating pipe line mostly is the structure parallel with the urea pipe simultaneously, be difficult to accomplish evenly be heated to each several part in the pipe, the time that urea melts fully in the pipe is long.
Summary of the invention
The technical problems to be solved in the utility model provide a kind of simple in structure, heat diesel urea pipeline heating equipment rapidly and uniformly.
For solving the problems of the technologies described above, the utility model comprises the urea pipe body, and its structural feature is to be wound with electric heating body at this external surface of urea pipe, and the electric heating body outer surface is provided with thermal insulation layer.
Between this external surface of pipeline and electric heating body, be provided with the metal stratum reticulare.
Described electric heating body appearance is enclosed with isolation layer.
After adopting said structure, owing to be wound with electric heating body at this external surface of urea pipe, by cooperating with the urea liquid control unit, just heat behind engine start, homogeneous heating can be elevated to-5 ℃ simultaneously with temperature and stop heating like this, control easyly, accurate, heating time is short.Through test, urea liquid can reach about 23 minutes fully at cold area (30 ℃) and melt in the pipe.
Description of drawings
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail:
Fig. 1 is a structural representation of the present utility model.
Embodiment
With reference to accompanying drawing, this diesel urea pipeline heating equipment comprises urea pipe body 1, because urea liquid has corrosivity, urea pipe body 1 nylon P12, be wound with electric heating body 4 at urea pipe body 1 outer surface, electric heating body 4 can be a carbon fibre electrothermal wire, it also can be the resistance wire that is enclosed with isolation layer 3, for homogeneous heating, quick heating, be provided with metal stratum reticulare 2 between pipeline body 1 outer surface and electric heating body 4, electric heating body 4 outer surfaces are provided with thermal insulation layer 5, can guarantee the higher efficiency of heating surface.This diesel urea pipeline heating equipment just heats behind engine start by cooperating with the urea liquid control unit, and homogeneous heating like this can be elevated to simultaneously-5 ℃ with temperature and stop heating, control easyly, accurate, and lack heating time.
Claims (3)
