Abstract
Disclosed is a diesel exhaust gas particulate filtering body gas thermal regeneration device which is characterized in that the device is composed of a filter body, a filtering body arranged in the filter body, a combustion chamber connected with the filtering body and an ignition device inserted into the combustion chamber; wherein the combustion chamber is connected with a vehicle gas storage tank through a main gas supply pipe, and the ignition device is also connected with the vehicle gas storage tank through a gas ignition supply pipe. The utility model has the advantages that firstly, the device has high regeneration efficiency, short regeneration time, safe and reliable regeneration; secondly, the gas regeneration way realizes the regeneration of the filtering body in the filtering process and avoids the pollution caused by the exhaust gas in the regeneration process of the filtering body; thirdly, the gas regeneration way is easy to be controlled without restrict demand to the carbon deposit quantity in the filtering body and with bigger selective range of regeneration chances; fourthly, the device has simple structure, light weight and small size; fifthly, the gas is less consumed; and finally, the device has a wide application range.
Description
One, affiliated field:
The utility model relates to a kind of diesel oil engine exhaust micro particle filtering body fuel gas heating regeneration device.
Two, background technique:
At present, common Diesel Particulate Filter body regeneration techniques mainly contains following three kinds both at home and abroad:
1. electric heating regeneration
Resistance wire is embedded in the filter, when needing regeneration resistance wire is switched on, make particulate be warming up to fire burns, realize filter regeneration.The reclaimer that utilizes this method to use is had relatively high expectations to electric energy, and power generally will reach more than the 1.5KW, generally needs special high-capacity battery or the high-power generator of being equipped with, and makes troubles to application.In addition, because the poor thermal conductivity of ceramic filtering body, so the recovery time is long, the uniformity of regeneration and completeness are not easy to guarantee.
2. the combustion-supporting regeneration of oil spout
During filter regeneration, utilize special nozzle to spray a certain amount of diesel oil and air supply to filter, light diesel oil by special ignition mechanism subsequently, the particulate in the filter of igniting is realized regeneration.Utilize the combustion-supporting reclaimer complex structure of the used oil spout of this method, regenerative process is difficult to control, causes filter to damage easily, also can cause secondary pollution.
3. reverse jet regenerating
This device can only be used for wall-flow honeycomb ceramic filter.During regeneration filter is passed to reverse high velocity air, the particulate of filter deposition blows down, and is collected by special gathering-device, utilizes Electric heating appliance to burn again.This apparatus structure complexity, very high to the requirement of sealability, and also work the time need consume a large amount of pressurized air, needs transform the air braking systems of vehicle.
Three, summary of the invention:
The purpose of this utility model just is to overcome above-mentioned the deficiencies in the prior art, and a kind of regeneration efficiency height is provided, and can avoid the diesel oil engine exhaust micro particle filtering body fuel gas heating regeneration device of exhaust pollution in the regenerative process.
The technical solution of the utility model is: a kind of diesel oil engine exhaust micro particle filtering body fuel gas heating regeneration device is characterized in that: by filter body and within it filter is installed, the firing chamber that joins with filter and the ignition mechanism of inserting in the firing chamber form; The firing chamber is connected with vehicle-mounted gas holder by combustion gas master supplying pipe, and ignition mechanism is connected with vehicle-mounted gas holder by the gas ignition supplying pipe.
Above-mentioned firing chamber is tubaeform, and has several holes thereon.
The high-temperature metal silk screen is equipped with in above-mentioned filter and connecting part, firing chamber.
On the above-mentioned gas ignition supplying pipe reduction valve is installed.
The utility model has the advantages that: 1, filter adopts combustion gas thermal regeneration mode, the regeneration efficiency height, and the recovery time is short, and safe and reliable.2, the combustion gas regenerated way has realized that filter regenerates in filter process, the pollution that exhaust causes when avoiding filter regeneration.3, the combustion gas regeneration method is convenient to control, and not tight to carbon deposition quantity requirement in the filter, the range of choice of regeneration opportunity is bigger.4, simple in structure, in light weight, volume is little.5, the gas quantity of Xiao Haoing is few.6, applied widely, be not only applicable to diesel car, also can be used for engineering machinery, diesel power generation unit etc.7, be applicable to multiple filtering material.Nonmetal filter such as foamed ceramics, honeycomb ceramic filter, ceramic fiber can be utilized this device.
Four, description of drawings:
Accompanying drawing is the structural representation of diesel oil engine exhaust micro particle filtering body fuel gas heating regeneration method device therefor:
Five, embodiment:
A kind of diesel oil engine exhaust micro particle filtering body fuel gas heating regeneration device is characterized in that: by filter body 1 and within it filter 2 is installed, the firing chamber 3 that joins with filter and the ignition mechanism of inserting in the firing chamber 4 form; The firing chamber is connected with vehicle-mounted gas holder 6 by combustion gas master supplying pipe 5, and ignition mechanism is connected with vehicle-mounted gas holder by gas ignition supplying pipe 7.Above-mentioned firing chamber is tubaeform, and has several holes 8 thereon.High-temperature metal silk screen 9 is equipped with in above-mentioned filter and connecting part, firing chamber.Reduction valve 10 is installed on the above-mentioned gas ignition supplying pipe.The principle of this device is; Draw small amount of exhaust gas earlier and enter ignition mechanism, feed the part combustion gas and form mixed gas, light by spark plug 11 continuous arcings, most exhaust is after modes such as circulation expansion cross section, aperture feed-in reduce flow velocity, supply with combustion gas and form mixed gas uniformly with main, the flame ignition that forms by ignition mechanism again, exhaust afterwards heats up, the particulate that ignites is realized the regeneration of filter.
