Abstract
The utility model provides a heater used for diesel engine exhaust gas purification. The heater comprises a heating tube body, baffle plates, heating wires, a temperature controller and a temperature sensor. The baffle plates are disposed in the heating tube body. The heating wires are disposed in the heating tube body and are fixed on the baffle plates. The temperature controller is respectively connected with the heating wires and the temperature sensor. The temperature sensor is disposed on a side wall of the heating tube body. The heater used for diesel engine exhaust gas purification is simple in structure, low in cost, accurate in temperature control, sensitive in reaction, and high in heating efficiency. The heater can effectively improve temperature of exhaust gas generated by a diesel engine, and is beneficial for process of ternary catalytic reaction, and catalytic effect of a ternary catalytic reactor is greatly improved.
Description
Technical field
The utility model belongs to the automobile exhaust gas purifying installation field, and particularly a kind of diesel motor exhaust purifies and uses heater.
Background technology
Motor-vehicle tail-gas is one of primary pollution source of current atmosphere, HC, CO, NO in tail gas
xNot only environment is worked the mischief, 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 discharge standard has all been worked out in countries in the world, and has spent a large amount of manpower, material resources and financial resources and administer the discharging of motor-vehicle tail-gas, reduce to pollute.
At present, carry out purified treatment for the tail gas that automobile was produced take Diesel engine as power, general mechanical type filtration and the three-element catalytic of adopting reacts, when 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, and catalytic efficiency is not high.
The utility model content
The utility model purpose: the purpose of this utility model is to provide the high diesel motor exhaust purification heater of a kind of efficiency of heating surface.
Technical scheme: a kind of diesel motor exhaust that the utility model provides purifies uses heater, comprises heating body, baffle plate, heating wire, thermostat and temperature sensor; Described baffle plate is located in the heating body, and described heating wire is located in the heating body and is fixed on baffle plate; Described thermostat is connected with temperature sensor with heating wire respectively; Described temperature sensor is located on the sidewall of heating body.
As improvement, described baffle plate is consistent with the centerline direction of heating body.
Improve as another kind, the quantity of described baffle plate is two, and is orthogonal, and consistent with the centerline direction of heating body.
Improve as another kind, described heating wire is fixed on baffle plate in the shape of a spiral.
Beneficial effect: diesel motor exhaust that the utility model provides purify, temperature control simple, with low cost with heater structure accurately, be quick on the draw, the efficiency of heating surface is high, it is arranged between Diesel engine and three-way catalytic converter, can effectively improve the temperature of the tail gas of Diesel engine generation, be conducive to the carrying out that three-element catalytic reacts, greatly improved the catalytic effect of ternary catalyzing unit.
