Description
Technical Field
The utility model relates to a particle catcher, especially a particle catcher who adopts special hole sealing mode.
Background
In order to meet the requirements of national six-emission regulations of diesel engines, the mainstream carrier layout scheme adopted by the existing diesel engine post-treatment system is DOC + DPF + SCR + ASC, wherein the light diesel vehicle generally adopts a silicon carbide DPF which has high temperature resistance, high mechanical strength and large carbon carrying capacity due to the working conditions of small engine displacement, urban areas or suburbs.
The carborundum wall-flow formula particle trap before generally adopts the cross hole sealing mode, like patent a large-scale diesel engine tail gas catalytic treatment device (publication number CN204299657U), including four at least fan-shaped column bodies, fan-shaped column body splices into the cylinder, and this internal a plurality of first air vents that are equipped with of fan-shaped column, first air vent are connected to the inlet end at fan-shaped column body both ends and give vent to anger the end, and the inlet end adopts the cross hole sealing mode, and two adjacent fan-shaped column bodies are connected through keeping apart the bonding region. The tail gas enters from the air inlet end of the opening and then forcibly passes through the hole wall to flow out from the opening of the air outlet end, and because a large number of micropores exist in the hole wall, carbon smoke particles in the tail gas are trapped, so that the purpose of reducing the particles of the tail gas is achieved.
But the defect of adopting this kind of hole sealing mode is also very obvious, because the filter area is less, and the volume of holding the ash is lower, and the cycle of maintenance is very short, and long-time particulate matter piles up in micropore department simultaneously, causes the micropore to warp or seriously block up, causes the problem that life shortens.
SUMMERY OF THE UTILITY MODEL
Utility model purpose: the utility model aims to solve current wall flow type particle trap because filter area is less, and the volume of holding the ash is lower, and the cycle of maintaining is just very short, and long-time particulate matter is piled up in micropore department simultaneously, causes the micropore to warp or seriously block up, causes the problem that life shortens.
The technical scheme is as follows: the utility model provides a following technical scheme:
the utility model provides an adopt particle trap of special hole sealing mode, comprises columniform particle trap body, and particle trap body one side is the inlet end, and one side is for giving vent to anger the end, and the particle trap body comprises a plurality of square air vents, faces mutually by four square air vents and leans on the square set of constitution as a trap unit, and the hole sealing of a square air vent of the inlet end of every trap unit, all the other square air vents do not seal the hole, and all square air vents one side hole sealing, the opposite side does not seal the hole.
At least one square vent hole which is not in a cross hole sealing mode exists in all the square vent holes at the air inlet end of the particle catcher body, so that the particle catching surface is enlarged. However, the positions of the square air holes for sealing the holes of all the trap units can be different, so that if a disordered mode is adopted, the holes can be sealed disorderly on the end surfaces of the air inlet end and the air outlet end of the particle trap body, the back pressures of all the hole walls are different, the seriously blocked hole walls exist, and the whole service life of the particle trap body is influenced.
Further, the positions of the sealed square vent holes of all the trap units are the same.
At least one arbitrary side of all the square air holes of the air inlet end of the particle catcher body is not adjacent to the square air holes of the hole sealing of the air inlet end, so that the particle catching surface is further enlarged, the back pressures of the hole walls are basically consistent, and the problem that the specific hole wall position is easy to wear due to the large back pressure is solved.
Furthermore, on one side of the air outlet end of the particle trap body, each trap unit is provided with three square air vent holes for sealing, and one square air vent hole is not sealed.
Furthermore, all the cross sections of the square vent holes along the extending direction of the vent holes are square and have equal side length.
Furthermore, all the square vent holes have the same length along the extending direction of the vent holes, and the sealing depth is the same.
Has the advantages that: compared with the prior art:
adopt the utility model discloses a design, can have an arbitrary limit in all square air vents of inlet end of particle trap body at least and all not adjacent with the square air vent of inlet end hole sealing for the increase of particle capture face improves and holds the ash volume, and is corresponding, has also prolonged the life of trap.
