Abstract
The utility model discloses a catalytic cleaner for tail gas particles of a diesel vehicle. The catalytic cleaner comprises a shell and a carrier. The carrier is a spiral structure stacked and wound by two corrugated plates. When the carrier is unfolded and laid, the ripples of the two corrugated plates are crossed, and the included angle between each ripple of the width direction of the corrugated plates is 30-60 degrees. Due to the fact that ripples of the two corrugated plates are crossed, the contact area of tail gas and the carrier is increased, the contact time of the tail gas and the carrier is prolonged, sufficient catalytic reaction is achieved, the activity and efficiency of the catalytic cleaner are increased evidently, and particle accumulation in the catalytic cleaner is reduced.
Description
Technical field
The utility model relates to a kind of Diesel exhaust particles extracts catalytic cleaner.
Background technique
According to statistics, the PM discharge amount in exhaust gas from diesel vehicle surpasses 90% of national vehicular emission PM total amount.In other words, the main source of PM in the PMShi China pollution of atmosphere in exhaust gas from diesel vehicle.PM discharge in exhaust gas from diesel vehicle has badly influenced urban air-quality and human lives is healthy, has affected socioeconomic sustainable development.In exhaust gas from diesel vehicle, the improvement of PM is very urgent.
Diesel particulate thing filter DPF (Diesel Particulate Filter) technology is the Diesel exhaust particles extracts processing mode that the developed countries such as America and Europe comparatively praise highly.The material of DPF has three kinds of silicon carbide, steinheilite and aluminium titanates, the similar honeycomb ceramic carrier of structure.But every two the adjacent ducts of carrier filter core, Yi Ge inlet is plugged, and another is plugged in outlet port.Tail gas, from a duct flows into, must flow out from adjacent duct through the crystallite hole of duct internal face like this, and the particulate matter in tail gas is trapped on the wall that is deposited on duct, realizes the filtration of particulate matter in tail gas.DPF can only be deposited on particulate matter in filter core, and itself is remove particulate matter not, and easily the blocked engine exhaust back pressure that causes raises, so the key that DPF continues to apply is its regeneration.DPF generally comes auxiliary combustion to remove the carbon granule of piling up by passive regeneration systems such as oil spout after additional or electric heating systems.This need to carry out supporting demarcation with DPF system at the engine calibration initial stage, simulates various actual operating modes, determines the condition of regeneration, accurate regeneration condition is enrolled in ECU control panel, with guarantee DPF can be smoothly, rationally regeneration.This calibration process is very complicated, of a high price, is not suitable for China's state-of-the-art, and especially China is huge by appearance of vehicle amount, again to existing, does not possess market viability carrying out DPF system layout with car engine.
Summary of the invention
Problem to be solved in the utility model is to provide a kind of Diesel exhaust particles extracts catalytic cleaner, significantly improves activity and the efficiency of catalytic cleaner, reduces the accumulation of particulate matter in catalytic cleaner.
In order to solve the problems of the technologies described above, the utility model adopts following technological scheme: a kind of Diesel exhaust particles extracts catalytic cleaner, comprise housing and carrier, described carrier is the helix structure that two corrugated sheets are superimposed, reel to form, and ripple and the angle between corrugated sheet width direction on arranged in a crossed manner and two corrugated sheets of ripple when described carrier launches tiling on two corrugated sheets are 30～60 °.The ripple intercross arrangement of two corrugated sheets has increased the area of contact of tail gas and carrier, extended the time of contact of tail gas and carrier, make the more abundant of catalytic reaction generation, significantly improved activity and the efficiency of catalytic cleaner, reduce the accumulation of particulate matter in catalytic cleaner.
Improved, described housing comprises the suction tude of arranging successively along discharge directions, the air inlet end cap that is connected in suction tude outlet side, the cylindrical shell that is connected in air inlet end cap outlet side, be connected in the end cap and be connected in the steam outlet pipe of the end cap outlet side of giving vent to anger of giving vent to anger of cylindrical shell outlet side, the inlet end of described suction tude is provided with flange, and the outlet side of described steam outlet pipe is provided with flange.
Improved, described carrier is built in cylindrical shell, and the front end of described cylindrical shell exceeds the front end setting of carrier, and the rear end that described cylinder back-end exceeds carrier arranges.Be convenient to that air-flow is uniformly distributed and being connected of cylindrical shell and air inlet end cap, the end cap of giving vent to anger.
Improved, described barrel front end is 5～15mm to the distance of carrier front end, and described cylinder back-end is 5～15mm to the distance of carrier rear end.The length that reasonably distance makes cylindrical shell can be not long and take too much space, guarantees that air-flow is uniformly distributed simultaneously.
Improved, described carrier and cylindrical shell are by the fixing welding of cross pin or vacuum brazing.Easy to connect and firm.
Improved, the ripple spacing on described corrugated sheet is 2～8mm, and the ripple height on described corrugated sheet is 1～2mm.Corrugated sheet has rational air-flow duct after reeling, and guarantees that tail gas fully contacts with carrier, makes the more abundant of catalytic reaction generation.
Improved, described corrugated sheet is wire gaze, and the order number of described wire gaze is 80～120 orders.
Beneficial effect:
Adopt after technique scheme, a kind of Diesel exhaust particles extracts catalytic cleaner of this model utility, the ripple intercross arrangement of two corrugated sheets has increased the area of contact of tail gas and carrier, extended the time of contact of tail gas and carrier, make the more abundant of catalytic reaction generation, significantly improved activity and the efficiency of catalytic cleaner.
