Abstract
The invention discloses an SCR system urea box adopting exhaust gas for heating. The SCR system urea box comprises a urea box body, the top of the urea box is provided with a liquid injecting opening, a liquid outlet is formed in the bottom of the urea box, an air inlet pipe is arranged on the upper portion of the urea box, an air outlet pipe is arranged on the lower portion of the urea box, a heat exchanger is arranged between the air inlet pipe and the air outlet pipe in the urea box, and four positioning holes vertically penetrating through the urea box are formed in the urea box. The engine exhaust gas can be used for heating a urea aqueous solution, and therefore heat energy of the engine exhaust is fully used.
Description
Technical field
The present invention relates to automobile exhaust system field, particularly a kind of SCR system urea box that adopts waste gas heating.
Background technique
The electrically heated method of the general employing of urea box that diesel engines at present reprocessing SCR system is used is carried out heating urea solution, strip heater is positioned at urea box house, by storage battery, electric-heating-wire-heating is powered, when temperature is too low, start working, to avoid the too low aqueous solution of urea that causes of temperature to freeze.Heater in this structure urea box, due to needs storage battery power supply, has therefore consumed the electric energy of vehicle.Electric power storage ability to storage battery is had higher requirement, and the storage battery in general commercial car can not be satisfied the demand, and need to change the storage battery that accumulation of energy is larger, has increased integral vehicle cost.
This system, by the circulating water heating urea liquid of motor, reduce the consumption of electric energy, but this system will increase the ability to work of engine radiator, and the radiation system of motor is needed to redesign.
Its shape of the automobile urea box of prior art is generally cuboid shape, the outer surface of automobile urea box is plane type, the automobile urea box mechanical strength of this structure is low, in the process of automobile running, easily produce high-frequency vibration, cause being arranged between liquid level sensor on urea box and urea box loosening, produce leakage, can affect like this working life of urea box; In addition, the high-frequency vibration of urea box can produce a large amount of noises.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of, to solve the above-mentioned multinomial defect causing in prior art.
For achieving the above object, the invention provides following technological scheme: a kind of SCR system urea box that adopts waste gas heating, comprise urea box body, the top of described urea box is provided with spout, the bottom of urea box is provided with liquid outlet, and the top of urea box is provided with suction tude, and the below of urea box is provided with steam outlet pipe, between the inherent suction tude of urea box and steam outlet pipe, be provided with heat exchanger, urea box is provided with 3 positioning holes that vertically pass urea box.
Preferably, described heat exchanger is hollow heat dissipating pipe.
Preferably, the cone structure that described urea box bottom makes progress for large mouth, liquid outlet is positioned at the bottom of cone structure.
Preferably, the sidewall of described urea box is provided with liquid level peep hole.
Adopt the beneficial effect of above technological scheme to be: the SCR system urea box of structure of the present invention, adopt engine exhaust to heat to aqueous solution of urea, the heat energy of abundant engine exhaust, do not need to use the electric energy of car load storage battery, saved the energy consumption of car load, and simple in structure, heat exchange is even, and heat exchange efficiency is high.Also without engine cooling system is redesigned, reduced the cost of exhaust treatment system, economic environmental protection, urea box is provided with 4 positioning holes that vertically pass urea box, for whole urea box is positioned, urea box is fixed on automobile, like this in the process of automobile running, urea box body is difficult for producing high-frequency vibration, so just can not produce noise, extended the working life of automobile urea box, heat exchanger is hollow heat dissipating pipe, can fully heat aqueous solution of urea, urea box bottom is cone structure, bottom is provided with liquid outlet, conveniently urea box is cleared up, the sidewall of urea box is provided with liquid level peep hole, preventing that aqueous solution of urea from adding too much overflows.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Wherein, 1--urea box, 2--spout, 3--liquid outlet, 4--suction tude, 5--steam outlet pipe, 6--hollow heat dissipating pipe, 7--liquid level peep hole, 8--positioning hole.
Embodiment
Below in conjunction with accompanying drawing, describe the preferred embodiment of the present invention in detail.
Fig. 1 shows the specific embodiment of the present invention: the SCR system urea box of this employing waste gas heating, comprise urea box 1 body, the top of described urea box 1 is provided with spout 2, the bottom of urea box 1 is provided with liquid outlet 3, the top of urea box 1 is provided with suction tude 4, the below of urea box 1 is provided with steam outlet pipe 5, between the inherent suction tude 4 of urea box 1 and steam outlet pipe 5, be provided with heat exchanger, urea box 1 is provided with 3 positioning holes 8 that vertically pass urea box 1, heat exchanger is hollow heat dissipating pipe 6, the cone structure that urea box 1 bottom makes progress for large mouth, liquid outlet 3 is positioned at the bottom of cone structure, the sidewall of urea box 1 is provided with liquid level peep hole 7.
The SCR system urea box of structure of the present invention, adopts engine exhaust to heat to aqueous solution of urea, and the abundant heat energy of engine exhaust does not need to use the electric energy of car load storage battery, the energy consumption of having saved car load, and simple in structure, heat exchange is even, and heat exchange efficiency is high.Also without engine cooling system is redesigned, reduced the cost of exhaust treatment system, economic environmental protection, urea box 1 is provided with 4 positioning holes 8 that vertically pass urea box 1, for whole urea box 1 is positioned, urea box 1 is fixed on automobile, like this in the process of automobile running, urea box 1 body is difficult for producing high-frequency vibration, so just can not produce noise, extended the working life of automobile urea box 1, heat exchanger is hollow heat dissipating pipe 6, can fully heat aqueous solution of urea, urea box 1 bottom is cone structure, bottom is provided with liquid outlet 3, conveniently urea box 1 is cleared up, the sidewall of urea box 1 is provided with liquid level peep hole 7, preventing that aqueous solution of urea from adding too much overflows.
Above-described is only the preferred embodiment of the present invention, it should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise of the invention, can also make some distortion and improvement, and these all belong to protection scope of the present invention.
