Description
Technical field
The present invention relates to vehicle maintenance service technical field, particularly a kind of tailed-gas treater of automobile.
Background technology
Not only smell is strange for vehicle exhaust, and makes us dizzy, nausea, and influence people's is healthy.Few in vehicle
In the case of, the self-purification capacity of air can still dissolve the toxin of automobile discharge.But with sharply increasing for automobile quantity, traffic congestion
Got married normal potluck, and convenient, comfortable, the efficient advantage that automobile should possess gradually is offset by excessive vehicle.Current vapour
The method of tailstock gas disposal mainly has following three kinds of approach：One is seeking cleaning new energy instead of original oil gas energy；Its
Two be improvement machine power, allows the energy transformation ratio of oil gas to improve so that engine is improved to the utilization efficiency of oil gas, reduces wave
Take；The third is being handled using outer purifier vehicle exhaust.Now, the treatment effect of car vehicle exhaust is obtained
Obvious improvement, but the vehicle maintenance service effect of truck is good.
Chinese invention patent CN 204627714U disclose a kind of automobile exhaust gas processing apparatus, and processing unit is from gas
Body entrance sets gradually filtering layer unit, blower fan and three-element catalytic list into gas vent exhaust emissions pipeline；In three-element catalytic list
Heater is set in member, for ternary catalyzing unit, with heater in the transmitter Cold Start of ternary catalyzing unit
Heated, and stop heating after the temperature of ternary catalyzing unit reaches setting value.
The content of the invention
The technical problem to be solved in the invention is to provide a kind of simple in construction and fixed intact vehicle maintenance service dress
Put.
For solve above-mentioned technical problem, a kind of tailed-gas treater of automobile of the invention, including filter element and
Catalytic reactor, is connected with blower fan between the filter element and catalytic reactor, the catalytic reactor includes urea reaction
Core body, the urea reaction core body, which has been wrapped around, is provided with basalt fibre insulation on the outside of heating endless tube, the heating endless tube
Retention mechanism is provided with the outside of layer, the basalt fibre heat-insulation layer；The urea reaction core body and basalt fibre heat-insulation layer
Between be provided with temperature sensor.
Further, the retention mechanism is clip, and the tightening nut tail end of the clip is provided with empennage.
Further, the filter element is from gas access to gas vent to set gradually work in the blast pipe of closing
Property charcoal filter layer, HEPA filter layer and Nanofiber filter layer.
After said structure, the present invention is heated by heating endless tube to urea reaction core body, then causes tail gas
Occurs gasification reaction generation water with urea；In addition, the reaction temperature compared to asbestos at 230 DEG C can produce noxious material, this hair
It is bright that 230 DEG C of reaction temperature and safety non-toxic can be preferably maintained at by basalt fibre heat-insulation layer.
Brief description of the drawings
The present invention is further detailed explanation with reference to the accompanying drawings and detailed description.
Fig. 1 is a kind of structural representation of tailed-gas treater of automobile of the invention.
Fig. 2 is the cross section structure schematic diagram of catalytic reactor of the present invention.
In figure：1 is filter element, and 2 be catalytic reactor, and 3 be blower fan,
101 be activated carbon filter layer, and 102 be HEPA filter layer, and 103 be Nanofiber filter layer, and 201 be urea reaction core
Body, 202 be basalt fibre heat-insulation layer for heating endless tube, 203, and 204 be temperature sensor, and 205 be clip, and 206 be empennage
Embodiment
As depicted in figs. 1 and 2, a kind of tailed-gas treater of automobile of the invention, including it is arranged on vehicle exhaust row
Endotracheal filter element 1 and catalytic reactor 2, blower fan 3 is connected between the filter element 1 and catalytic reactor 2.It is described
Catalytic reactor 2 includes urea reaction core body 201, and the urea reaction core body 201 has wrapped around heating endless tube 202, described

Gu mechanism；Temperature sensor 204 is provided between the urea reaction core body and basalt fibre heat-insulation layer.
Further, as shown in Fig. 2 the retention mechanism is clip 205, for the ease of rotating the tightening nut of clip,
The tightening nut tail end for being easily installed and dismantling the clip is provided with empennage 206.
Further, the filter element is from gas access to gas vent to set gradually work in the blast pipe of closing
Property charcoal filter layer 101, HEPA filter layer 102 and Nanofiber filter layer 103.
The present invention is heated by heating endless tube to urea reaction core body, then causes tail gas to occur gasified reverse with urea
Water should be generated；In addition, the reaction temperature compared to asbestos at 230 DEG C can produce noxious material, the present invention passes through basalt fibre
Heat-insulation layer can preferably be maintained at 230 DEG C of reaction temperature and safety non-toxic.
Although the foregoing describing the embodiment of the present invention, those skilled in the art should be appreciated that this
It is merely illustrative of, various changes or modifications can be made to present embodiment, without departing from the principle and essence of invention, sheet
