Description
Technical field
The utility model relates to a kind of catcher, relates in particular to a kind of spiral oxidation catcher.
Background technique
Grain catcher is a kind of porcelain filter being arranged in diesel engine emissions system, and it can be by its seizure before Particulate Emission material enters atmosphere.The pollution of diesel engine is mainly from three aspects---Particulate Emission material, hydrocarbon (HCx), nitrogen oxide (NOx) and sulphur.Wherein Particulate Emission material (cigarette ash) major part is made up of the molecule of carbon or carbide.
Particle trap can reduce the cigarette ash that diesel engine produces and reach more than 90%.The Particulate Emission material capturing burns totally subsequently in vehicle operation process.Its work basic principle is: metal platinum as upper in diesel particulate filter spraying, rhodium, palladium, the black smoke that contains carbon granule that diesel engine is discharged, enter motor exhaust particle trapper by special pipeline, through the bag filter of its inner intensive setting, charcoal cigarette particulate is adsorbed on the filter that metal fiber felt makes; After the extent of adsorption of particulate acquires a certain degree, the burner auto-ignition combustion of tail end, burns superincumbent absorption charcoal cigarette particulate, becomes harmless carbon dioxide and discharges.In order to accomplish this point, catcher has been applied advanced automatical control system, catalyst coatings and fuel addition type catalyzer (FBC).This fuel addition type catalyzer comprises metals such as cerium, iron and platinum.These materials join in fuel in proportion, not only control the quantity of Particulate Emission material under the help of engine control system, but also control the discharge amount of the pollutants such as hydrocarbon and dusty gas.The regeneration of catcher or purification function must complete on controlled basis, to keep catcher not stopped up by cigarette ash.After purification cycle finishes, any residual dust or filter residue finally all will be removed artificially in regular maintenance.
Diesel particulate catcher can reduce the discharge of particulate matter effectively, and it first traps the particulate matter in waste gas, and then the particulate of trapping is oxidized, and makes particle trap regeneration.The regeneration of so-called filter refers in DPF long-term work, and the particulate matter in catcher gradually increase can cause that engine back pressure raises, and causes engine performance to decline, so will regularly remove the particulate matter of deposition, recovers the strainability of DPF.The regeneration of catcher has initiative regeneration and two kinds of methods of passive regeneration: initiative regeneration refers to and utilizes outside energy to improve the temperature in catcher, makes particulate ignition.In the time that the temperature in catcher reaches 550 DEG C, the particulate matter of deposition will oxidizing fire, if temperature does not reach 550 DEG C, too much sediments will stop up catcher, at this moment just need to utilize external energy (for example electric heater, the change of burner or engine operating condition) improve the temperature in DPF, make particulate matter oxidizing fire.Passive regeneration refers to the kindling temperature of utilizing fuel oil additive or catalyzer to reduce particulate, make particulate can be at normal diesel exhaust gas temperature ignition.Additive (having cerium, iron and strontium) will be added in fuel oil in certain proportion, and additive too much can affect the life-span of DOC (diesel oxidation catalyst), if but very few, will cause regeneration delays or regeneration temperature to raise.
Existing grain catcher technology adopts straight-through type Trapping ways.Filter prepass and filter screen are direct current type, and area of contact is limited.
Model utility content
The utility model, according to above-mentioned deficiency, provides a kind of spiral oxidation catcher.
For achieving the above object, the technical solution of the utility model is: a kind of spiral oxidation catcher, by housing, waveform filtrating equipment group, vent, center hole, filter core composition, described waveform filtrating equipment component becomes left waveform filtrating equipment and right waveform filtrating equipment, one end interconnection of left waveform filtrating equipment and right waveform filtrating equipment, hole centered by the hole that the interconnection of 30-40 group corrugated sheet filtrating equipment group forms, the other end intersects at edge in housing, be connected with housing, point of intersection, two ends is terminal, all corrugated sheet filtrating equipment groups are combined to form sped structure.
Described left waveform filtrating equipment and 4-7 right waveform filtrating equipment interconnection, infall forms vent.
Described filter core is arranged in described vent.
The beneficial effects of the utility model are: grain catcher the inside is a screw type passage, and particulate matter enters rear continuous and conduit wall collision, thereby reduces particulate matter speed, and then is better oxidized.
