Abstract
Traditional vehicle catalyst converter is within a period of time of vehicle launch, and since catalyst is not yet by flue gas to active temperature, the flue gas in the stage cannot be cleaned processing, and the hazardous contaminants such as a large amount of NOx and hydrocarbon HC are discharged.The invention discloses a kind of Vehicular exhaust catalytic cleaner, including catalytic unit that can utmostly eliminate vehicle launch stage exhaust emissions itself and catalyst preheating systems.The carrier of the catalytic unit coats electro-thermal coatings first, and the electro-thermal coatings are coated with catalyst coat outside using the excellent electric heating materials such as carbon fiber, the electrothermal layer.Before internal combustion engine start the catalyst coat of the appearance is heated rapidly to its active temperature range in advance using electrothermal layer by being remotely controlled induction, allow to start vehicle internal combustion engine again, and stop heating of the exterior source of energy to catalyst, thus the combustion tail gas in the stage is able to effectively be catalyzed reaction, to remove the pollutants such as NOx therein.
Description
Technical field
The present invention relates to a kind of tail gas disposal technique fields effectively removing vehicle launch stage tail gas pollution, especially relate to
And one kind can pre-warmed Vehicular exhaust catalytic cleaner, it is the various vehicles of power and mechanical dress to be suitable for use internal combustion engine
It sets.
Background technology
Catalytic cleaner refers to that the pernicious gases such as NOx, CO that Vehicular exhaust is discharged and hydrocarbon HC are passed through oxidation
It is changed into the catalytic unit of harmless nitrogen gas and water and carbon dioxide with reduction.Three-way catalyst is minimum Celsius 250
It reacts when spending, when temperature is too low, transfer efficiency drastically declines, and the active best operating temperature of catalyst is 400
DEG C to 800 DEG C or so.Conventional catalyst clarifier is generally seated in from about 1.2 m of engine export at present, is started in engine
In preceding 200 s of work, the bed temperature of catalyst is below 250 DEG C, the initiation temperature without reaching catalyst, therefore nothing
Method plays catharsis to the pollutant discharged during cold start, especially in north cold area.The vehicle launch stage due to
Internal combustion engine is needed to provide the combustion power more much bigger than the normally travel stage to obtain corresponding acceleration, the burning of fuel is less filled
Point, so the pollutant of its discharge is more, toxicity bigger.
Invention content
The purpose of the present invention is that solve the above-mentioned problems and provides one kind and effectively removing vehicle launch stage tail gas
The catalyst converter of pollution.
The present invention is achieved through the following technical solutions above-mentioned purpose.
A kind of Vehicular exhaust catalytic cleaner effectively removing vehicle launch stage tail gas pollution, the design of catalyst converter carrier
For honeycomb, pore surface is catalyst layer, and electric heating layer is added between catalyst layer and carrier, uses carbon fiber
Etc. excellent thermo electric material；Meanwhile as the honeycomb structure carrier of carrier be poor conductive insulating materials.The electricity of entire catalyst converter
Heating layer is connected, and is connected to vehicle-mounted electric-heating source by unified interface, controls its break-make by central processing unit, sees principle
Schematic diagram.Wherein specific honeycomb skeleton structure and can be with the general industrial design that is coupled as of electric heating layer and catalyst layer
It realizes, the engineers and technicians that usually obtain employment are understood that and complete, and scheme is such as according to current industrial coating technology, Ke Yi
Suitably increase its honeycomb porosity on the basis of existing catalyst converter carrier framework, first covers electric heating coating on basic skeleton, then
The catalyst layer on electrothermal layer；Can also be newly added in the tail portion of former catalyst converter such a has intermediate electrical heating interlayer
Netted catalyst converter can be used multilayer and be combined together.Conceptual design forms different in this way does not affect the protection model of the present invention
It encloses.
Before the internal combustion engine start of vehicle, the remote control of carrying is first turned on the switch energization by vehicle driver, works as entrance
After the active induction range of vehicle remote control inductor, remote control inductor sends instruction by corresponding central processing unit, makes catalysis
Device electric heating layer electrified regulation catalyst layer is catalyzed by being embedded in the temperature sensor measurement of the catalyst layer heating process
The temperature change of oxidant layer, when its temperature is more than catalyst activity temperature certain value, such as up to 300 DEG C or more, catalyst has enough
Catalytic activity, then allowed by central processing unit to start vehicle internal combustion engine, cut off external heat source to electric heating simultaneously after internal combustion engine start
The heating of layer.In this way, the pollutions such as NOx, CO and hydrocarbon HC in the startup stage of vehicle can just make combustion product gases
Object reacts removing in time.And traditional vehicle catalytic cleaner as previously mentioned, starting stage after vehicle internal combustion engine startup by
Active temperature has not yet been reached in catalyst and makes in a large amount of toxic pollutants discharge environment in flue gas.The catalyst of the present invention
Traditional three-way catalyst can be used, using different catalysts, control the temperature for cutting off heating in the central processing unit of electric heating layer
It spends depending on active temperature range of the limit value by used catalyst.
The connection encapsulation of the wherein elements such as central processing unit, remote signal inductor, catalyst layer temperature sensor is same
The common operation for belonging to industrial design in related field is not difficult to realize, different designs is also for correlation engineering technical staff
Do not influence protection scope of the present invention.
The beneficial effects of the present invention are：It can carry out catalyst warm-up in advance prior to the startup of vehicle internal combustion engine, it made to reach
Restart internal combustion engine after to enough active temperatures, utmostly to reduce or eliminate a large amount of dirts of vehicle launch stage emission
Dye, efficiently solves the associated disadvantages of current vehicle mounted tail gas catalytic cleaner, the catalyst converter excellent catalytic effect of respective design, structure
Simply, high catalytic efficiency.
Description of the drawings
Fig. 1 is a kind of structural principle signal letter of catalyst converter effectively removing vehicle launch stage tail gas pollution of the present invention
Figure.
Fig. 2 is setting for " sandwich " structure of the base material of honeycomb catalyst converter of the present invention, electric heating layer and catalyst layer
Count schematic diagram.
Specific implementation mode
The invention will be further described below in conjunction with the accompanying drawings.
As shown in Figure 1, a kind of catalyst converter effectively removing vehicle launch stage tail gas pollution, including central processing unit, packet
Flue gas honeycomb catalyst converter containing electric heating layer, the vehicle power supply for heating electro-thermal coatings, the temperature for measuring catalyst layer temperature
