Abstract
The utility model discloses a honeycomb ceramic disc electric heater which comprises a honeycomb ceramic disc, an electric heating element and a fixing part; the honeycomb ceramic disc is made of high temperature resistant ceramics to be a multi-pore structure; an electric heating wire or an electric heating pipe is adopted as the electric heating element which is shaped and fixed on the end face of the honeycomb ceramic disc by the fixing part through bending, coiling and other processing forms. Because of the special multi-pore structure, the honeycomb ceramic disc can not only fix and support the electric heating element, but also prevent heat radiation on one side of a bearing surface of the electric heating element, get air flow through the heater and heat the air flow through heat exchange. Therefore, the electric heater is in particular applicable in the heating and the recycling of diesel engine exhaust gas particle filters.
Description
Technical field
The invention belongs to the electric heater field, both can be used for the planar radiation heating, can be used for the air-flow heating again, be particularly suitable for the electric heating regeneration of diesel engine vent gas particulate filter.
Background technology
Along with countries in the world to the improving constantly of engine emission standard, in order to administer the pollution of motor vehicle to environment, various diesel motor exhaust purification treatment technologies and device arise at the historic moment.Wherein the electric heating initiative regeneration becomes one of important techniques type.China utility model patent ZL200620068031.1 discloses a kind of diesel engine vent gas granule capturing and regenerative system, it is characterized in that constituting by two groups of filters of alternately taking turns to change jobs, igniting regenerating unit, regeneration temperature checkout gear, air supply pipe road and the parallel connections of tail gas switch valve, both do not disturb mutually, independent operating, this system not only can filter the diesel motor exhaust particle, but also can regenerate to the filter that filters after saturated, and the repertoire of system and operation are carried out full-automatic closed-loop control by central electric control gear.This patented technology adopts the ignite carbon granule of filter end face of electric heating igniter, realized the thermal regeneration of filter, but this electric heating igniter thermal efficiency ratio is lower, and the time of heating is longer.
The utility model content
The purpose of this utility model is at the deficiencies in the prior art, a kind of efficient, reliable ceramic honey comb disc type electric heater is provided, the diesel vehicle particulate filter that is used for electric heating initiative regeneration type makes existing diesel vehicle particulate filter realize efficiently initiative regeneration fast.
The technical solution of the utility model is as follows:
A kind of ceramic honey comb disc type electric heater is characterized in that comprising ceramic honey comb dish, electrical heating elements, fixture; Electrical heating elements is fixed on the ceramic honey comb dish end face by fixture.
The ceramic honey comb dish can adopt the high temperature ceramic material processing and manufacturing to become loose structure.The shape in hole can be circular, ellipse and polygonal; Ceramic honey comb dish profile can be processed as circle, ellipse according to the difference of using installation environment, reach polygon etc.; The thickness of ceramic honey comb dish is not limit.
Electrical heating elements can be that an electrical heating wire or electric heating tube pass through form processing moulding such as bending or coiling, and its shape can be but be not limited to jatharapanvartanasana, vortex filament shape and the space bending shape that the plane bends; Also can be that many electrical heating wires or electric heating tube become planar array shape or space array shape by form processings such as bending or coilings.
Fixture adopts exotic material to shape, and its shape can be but be not limited to shapes such as " U " shape, " L " shape, " J " shape.
Because of but the distinctive loose structure of ceramic honey comb dish makes its both fixed support electrical heating elements, can stop the thermal radiation of electrical heating elements supporting surface one side again, also can allow air-flow pass this device, simultaneously by the heat exchange heating air flow.Therefore be specially adapted to the use of diesel engine vent gas particulate filter thermal regeneration.
The utility model product can be installed on the front end of wall-flow filter, and heating element is towards the filter end face.Entering filter at the porous channel of filtration stage motor exhaust by ceramic honey comb disc type electric heater filters.During thermal regeneration, electrical heating elements energising back produces hyperthermia radiation, to the front end intensification heating of filter.Because the preceding heating surface of this heater can very close filter, back heating surface is pressed close to the ceramic honey comb dish, and the ceramic honey comb dish has stopped thermal radiation backwards effectively, and this has just improved the heat efficiency greatly.Electrical heating elements can be designed to arrange symmetrically, has improved the uniformity of heating.Therefore, practical effect shows, compares with the electric heating igniter in the ZL200620068031.1 patent, and the heat efficiency improves more than 50%, and shortened more than 60% heating time.
