Abstract
The utility model provides a foam metal preheater for a diesel engine. The foam metal preheater comprises a heating pipe body (1), a temperature controller (2), as well as a temperature sensor (3), an upper foam metal layer (4), an electric heating wire (5) and a lower foam metal layer (6) which are arranged in sequence from top to bottom in the heating pipe body (1), wherein the temperature controller (2) is connected with the temperature sensor (3) and the electric heating wire (5) respectively; the temperature sensor (3) outputs detection signals into the temperature controller (2); the temperature controller (2) is used for controlling the electric heating wire (5). The preheater is simple in structure, low in cost, accurate in temperature control, sensitive in reaction and high in preheating efficiency. By placing the preheater between the diesel engine and a three-way catalytic converter, the temperature of tail gas produced by the diesel engine can be raised effectively, and the catalyzing effect of the three-way catalytic converter is enhanced.
Description
Technical field
The utility model belongs to automobile exhaust gas purifying installation field, particularly a kind of use for diesel engine foam metal formula preheater.
Background technique
Motor-vehicle tail-gas is one of primary pollution source of current atmosphere, and in tail gas, HC, CO, NOx not only work the mischief to environment, and the direct harm humans of meeting is healthy.In order to reduce the pollution of motor-vehicle tail-gas to atmosphere, more and more stricter emission standard has all been worked out in countries in the world, and spent a large amount of manpower, material resources and financial resources administer the discharge of motor-vehicle tail-gas, reduce pollute.
At present, carry out purified treatment for the tail gas that automobile was produced that is power with diesel engine, generally adopt mechanical type to filter and three-element catalytic reaction.But in the time adopting three-way catalytic converter to carry out purified treatment, because the temperature of diesel motor exhaust is lower, the catalytic effect that makes three-way catalyst is not very desirable, catalytic efficiency is not high, and treatment effect is bad.
Model utility content
Model utility object: in order to overcome above-mentioned the deficiencies in the prior art, the purpose of this utility model is to provide a kind of use for diesel engine foam metal formula preheater, so that tail gas reaches higher temperature before catalysis, improves catalytic efficiency.
Technological scheme: a kind of use for diesel engine foam metal formula preheater that the utility model provides, comprises heating body, temp controller and be located at successively temperature transducer, upper foam metal layer, electric heating wire, the lower foam metal layer in heating body from top to bottom; Described temperature controlling instrument is connected with electric heating wire respectively at temperature transducer, temperature transducer output detection signal to temperature controlling instrument, temperature controlling instrument control electric heating wire.
As improvement, described upper foam metal layer, electric heating wire, lower foam metal layer be arranged in parallel, and all vertical with the centerline direction of heating body.
Improve as another kind, described electric heating wire is spirality.
Beneficial effect: use for diesel engine foam metal formula preheater that the utility model provides is simple in structure, with low cost, temperature control accurately, be quick on the draw, the pre-thermal efficiency is high, be arranged between diesel engine and three-way catalytic converter, can effectively improve the temperature of the tail gas of diesel engine generation, improve the catalytic effect of ternary catalyzing unit.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model use for diesel engine foam metal formula preheater;
Fig. 2 is the utility model use for diesel engine foam metal formula preheater sectional drawing.
Embodiment
Below in conjunction with accompanying drawing, the utility model use for diesel engine foam metal formula preheater is made and being further illustrated.
Use for diesel engine foam metal formula preheater, is shown in Fig. 1 to 2, comprises heating body 1, temp controller 2 and is located at successively temperature transducer 3, upper foam metal layer 4, electric heating wire 5, the lower foam metal layer 6 in heating body 1 from top to bottom; Temperature controlling instrument 2 is connected with electric heating wire 5 respectively at temperature transducer 3, and temperature transducer 3 output detection signals are to temperature controlling instrument 2, and temperature controlling instrument 2 is controlled electric heating wire 5.Upper foam metal layer 4, electric heating wire 5, lower foam metal layer 6 be arranged in parallel, and all vertical with the centerline direction of heating body; Electric heating wire 5 is spirality.
The action principle of this use for diesel engine foam metal formula preheater is: this use for diesel engine foam metal formula preheater is fixed between diesel engine and three-way catalytic converter; In the time that the tail gas of diesel engine passes to heating body 1, the temperature of tail gas is conveyed to temp controller 2 by temperature transducer 3, temp controller 2 is controlled electric heating wire 5 energising heating, and in the time that temperature transducer 3 senses predetermined temperature (preferably 400-450 DEG C), temp controller 3 is controlled electric heating wire 5 and stopped heating; Thereby realize tail gas control temperature to improve the effect of catalytic efficiency.
