Abstract

A diesel particulate removing apparatus is provided which is capable of regenerating, with ease and at low costs, a function of a clogged filter. The diesel particulate removing apparatus is made up of an outer cylinder being attached, in an embedded manner, to an exhaust gas path of a diesel engine and having apertures on sides of flow-in and flow-out of diesel exhaust gas and two or more filter units being housed in the outer cylinder to collect or to collect and burn particulates contained in the diesel exhaust gas to remove them. The filter units are connected to each other along a flow of the diesel exhaust gas and combined with flow-out and flow-in cylinders for the diesel exhaust gas to make up an inner cylinder of a sealed structure, with portions on sides of the flow-in and flow-out of the exhaust gas being not included in the sealed structure.

Description

Particulate removal device and have the diesel-oil vehicle of this device
Technical field
The present invention relates to the particulate removal device, be particularly related to heater or filter and catch contained particulate in the waste gas of the internal-combustion engines such as diesel engine that diesel-oil vehicle, generator, agricultural machinery and implement etc. go up to use, or the diesel-oil vehicle that the particle burning of catching is removed employed particulate removal device and had this removal device.
Background technique
In the past, people were nitrogen oxide aspects such as (NOx) based on carcinogen nitrogen dioxide to the emphasis point of the regulation of automobile exhaust gas.
, have the carbon microsphere (so-called black smoke) of volume in diesel-oil vehicle waste gas, this carbon microsphere is after exhaust passageway is discharged in the air, and is floating in air for a long time, finally becomes coal ash etc. and dances in the air and drop on ground, road surface, the clothes etc.But, because of carbon has good adsorption, thus constantly there is report to show in recent years, on the carbon microsphere that is adsorbed in the air to be floated with various chemical substances such as carcinogenic related substances, this carbon microsphere is sucked and enters in the human body by the people, causes cancer or respiratory disease.
Therefore, now, be not limited only to nitrogen oxide (NOx), the discharge of the particulate material of diesel-oil vehicle (PM) is constrained to for important problem.So; avoid being subjected to the diesel oil black smoke pollution in order to protect ambient air; provide the black smoke acquisition equipment; this black smoke acquisition equipment is that configuration is removed filter (for example, with reference to patent documentation 1 and patent documentation 2) by the black smoke that steel fiber and honeycomb-like part etc. constitutes in vehicle-mounted diesel engine exhaust passage.
But this black smoke is removed filter, if long-term the use can be caused stopping up the problem that exists the so-called pressure loss to increase by catching black smoke.
As eliminating the means that black smoke stops up, motion has makes the particle burning of catching and the diesel particulate removal device (for example, referring to patent documentation 3, patent documentation 4 and patent documentation 5 etc.) of regeneration filter function.
This device possesses: have exhaust gas entrance and outlet cylindrical container, be arranged on the heater of the inlet side in this cylindrical container, at this heater rear portion in abutting connection with the porous foam filter of configuration, at the rear portion of this porous foam filter in abutting connection with the filter that is loaded with catalyzer of configuration.
In this structure, the waste gas that imports from inlet is contacting fire burns with heater that be made of pottery or metal, after the heating, catches the unburned particle of removal by porous foam filter and the filter that is loaded with catalyzer.At this moment, the heat in heater and the waste gas conducts to the porous foam filter, makes the unburned particulate of being caught by the porous foam filter fire burns.Be arranged in the more filter that is loaded with catalyzer in downstream side, few because of coming from the thermal change of heater and waste gas conduction, temperature descends, but by the catalyzer on the filter that is loaded with catalyzer, promote to catch the burning of particle, so can not stop working, more catch the particle removal of burning at a lower temperature, make the functional regeneration of filter.

, though it is desirable to have the structure of filter regeneration function in the built-in heater of device, there are the defective of poor durability in complex structure and cost height.
In addition, concerning stopping up the filter that does not also have to take place, in the diesel particulate removal device, when sharply flowing into the waste gas that contains a large amount of oxygen with black smoke, the interior unburned particle of diesel particulate removal device might occur burns explosively, be the phenomenon of so-called oxygen flash burn, and damage filter etc.
For example, in long descending etc., behind the waste-gas braking of braking using blocking-up waste gas, step under the situation of gas pedal, contain the waste gas of the oxygen of the gentle height concentration of diesel particulate (for example being common 4 times), sharply flow in the diesel particulate removal device, thereby meeting cause the burning of diesel particulate explosively, even reach nearly 1500 ℃, might melt as metal filter.
Summary of the invention
