Abstract
A method for regenerating the filter of exhausted particles by gas heating for diesel engine features that the gas and the oxygen in exhausted gas from diesel engine are mixed and ignited to heat the exhausted gas, and high-temp. exhausted gas can burn the particles in filter for regenerating it. Its equipment is composed of a filter, a burning chamber, and an ignitor in the burning chamber. Its advantages are high efficiency, high safety, no pollution, easy control and low consumption of gas.
Description
One, affiliated field:
The invention belongs to and relate to a kind of diesel oil engine exhaust micro particle filtering body fuel gas heating regeneration method and device therefor.
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.This reclaimer 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.The combustion-supporting reclaimer complex structure of oil spout, regenerative process are difficult to control, cause 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:
Purpose of the present invention 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 method and the device therefor of exhaust pollution in the regenerative process.
Technological scheme of the present invention is: a kind of diesel oil engine exhaust micro particle filtering body fuel gas heating regeneration method, it is characterized in that: the heating energy source when utilizing combustion gas to regenerate as filter, with diesel exhaust gas and combustion gas mixing, utilize the remaining oxygen in the exhaust to participate in burning, light the back thermal exhaust, make ignite exhaust gas particulate in the filter of exhaust-gas temperature rising, realize the regeneration of filter.
Above-mentioned combustion gas is rock gas or liquefied petroleum gas (LPG).
The method that adopts the exhaust classification to enter, concrete method is to draw small amount of exhaust gas earlier to enter ignition mechanism, feed the part combustion gas and form mixed gas, lighted by the continuous arcing of ignition mechanism, most exhaust is after modes such as circulation expansion cross section, aperture feed-in reduce flow velocity, with the main combustion gas formation mixed gas uniformly of supplying with, the flame ignition that forms by ignition mechanism again, afterwards the exhaust that heats up, the particulate that ignites is realized the regeneration of filter.
The equipment that above-mentioned diesel oil engine exhaust micro particle filtering body fuel gas heating regeneration method is used, 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.
The high-temperature metal silk screen is equipped with in above-mentioned filter and connecting part, firing chamber.
Above-mentioned firing chamber is tubaeform, and has several holes thereon.
On the above-mentioned gas ignition supplying pipe reduction valve is installed.
Advantage of the present invention is: 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, 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 method and equipment.
