It is clear that the discharge treatment facilities of existing engine exhaust, still undesirable perfect, there is improved necessity in fact.Hair A person of good sense is in view of this, special to create into the utility model, phase to grind and improve lacking for prior art by proposition of the present utility model Fall into, the phase enables the discharge of engine exhaust and purification function more they tends to improve and ideal, meets actual ecological requirements.

Utility model content

There is the defects of purification efficiency difference because EGT is not high enough to improve foregoing existing engine exhaust purifier, Engine exhaust purifier of the present utility model, its main purpose are：A kind of heat temperature raising technology of engine exhaust is provided, its A heating unit is had additional in waste gas purification apparatus, the EGT that can make to pass through using the heating unit is effectively lifted；Borrow This, when waste gas enters CC Catalytic Converter after heating, therefore the clean-up effect can be lifted, to obtain the mesh of effectively purification waste gas 's.

Secondary objective of the present utility model is：At the CC Catalytic Converter, a Lambda sensor is provided with, when amount of oxygen mistake Air can be filled into when low automatically, to meet to maintain the condition of CC Catalytic Converter normal operation, waste gas is effectively purified so as to obtaining Purpose.

To reach above-mentioned purpose, the specific technical scheme of the utility model is：The engine exhaust purifier is a row Tracheae, in its opposite end be respectively an air intake and an exhaust outlet；One first body is connected with the air intake end, this first Be provided with a heating unit at body, including a heating component located at first tubular body, it is one or more in Body, each interior tube body inner edge are provided with a heating coating；In addition, the first body inner edge is provided with an insulation material in the heating Component outer layer, so as to being incubated relative to first body.

The foregoing heating unit rear end is connected with a CC Catalytic Converter, namely the heating unit is located at the air intake and touched with this Between matchmaker's converter.

A Lambda sensor is provided with the foregoing CC Catalytic Converter, the Lambda sensor can be detecting CC Catalytic Converter The oxygen content at place, the Lambda sensor and a control assembly are electrically connected with, and are provided with one at the CC Catalytic Converter front end and are entered Tracheae, the air inlet pipe can be controlled by the control assembly and opened and closed；When Lambda sensor detects that amount of oxygen is too low, one can be transmitted Signal notifies the control assembly, so that the air inlet pipe is opened and fills into air automatically, to meet to maintain CC Catalytic Converter normally to transport The oxygen sufficiency of work.

Wherein, the Lambda sensor is located at the CC Catalytic Converter rear end.

Wherein, the heating coating is made up of platinum or rhodium either of which or its composition.

The beneficial effects of the utility model：

By setting of the present utility model, when the utility model is implemented, the purification effectiveness of engine exhaust can be effectively lifted, Richness tool industrial utilization.

Embodiment

Now with regard to the structure composition of engine exhaust purifier of the present utility model, and the effect of can be generated, coordinate accompanying drawing, It is as follows to lift a preferred embodiment detailed description of the present utility model.

First, referring to shown in Fig. 1, Fig. 2 and Fig. 3, engine exhaust purifier 1 of the present utility model is a blast pipe, In its opposite end be respectively an air intake 10 and an exhaust outlet 19；One first body 11 is connected with the end of air intake 10, should It is provided with a heating unit 2 at first body 11, including the heating component 22, one inside first body 11 or one Interior tube body 21 more than individual, each inner edge of interior tube body 21 is provided with a heating coating 24；In addition, the inner edge of the first body 11 is provided with One insulation material 23 is in the outer layer of heating component 22, so as to being incubated relative to first body 11.The foregoing heating unit 2 Rear end is connected with a CC Catalytic Converter 12, namely the heating unit 2 is located between the air intake 10 and the CC Catalytic Converter 12.

At the foregoing CC Catalytic Converter 12, it is particularly at the end of CC Catalytic Converter 12 and is provided with a Lambda sensor 13, the Lambda sensor 13 can be to detect the oxygen content at CC Catalytic Converter 12, the control group of Lambda sensor 13 and one Part 14 is electrically connected with, and is provided with an air inlet pipe 15 at the front end of CC Catalytic Converter 13, and the air inlet pipe 15 can be by the control assembly 14 controls open and close.

The foregoing heating coating 24, by platinum or rhodium, any one or its arbitrary composition are formed, and can have lifting temperature Effect.
