Abstract

The utility model relates to a black smoke particle filter for diesel engines, which is arranged on an exhaust pipe. The utility model comprises a filter chamber with an air inlet pipe and an air outlet pipe, wherein, the air inlet end of the filter chamber is provided with a flow distribution plate, the middle part of which is provided with micropore ceramic filter elements. Black smoke particles carried by waste gases can be filtered by the ceramic filter element, and thus the exhausted waste gases are relatively clean without black smoke. Thus the smoke dust pollution of atmosphere can be effectively reduced. The utility model has the advantage of reasonable structural design, can eliminate the present status of black smoke emitting caused by aging or at the time of coal of the traditional diesel engines, reduce the pressure to the environment, and improve the life quality through filtration of the waste gases with larger black smoke capacity.

Description

The black diesel smoke particulate filter

Technical field:

The utility model belongs to the diesel engine field, and particularly a kind of black diesel smoke particulate filter that is installed on the outlet pipe is used for the black smoke particle of filtering exhaust.

Background technique:

As everyone knows, diesel engine extensively applies on the industrial or agricultural field, not only improved manufacturing efficiency, and reduced labor intensity, along with development of technology, increasing Motor Vehicle also adopts diesel engine as power, is open to traffic as the common public transport in city, but it discharges the inadequate tail gas of burning, the negative effect that also brings befouling environment simultaneously.

Summary of the invention:

The purpose of this utility model is a kind of black diesel smoke particulate filter that reduces exhaust pollution by micropore ceramics core physical filtering of design.

Technical solutions of the utility model are achieved in that a kind of black diesel smoke particulate filter, comprise that one has the filter chamber into and out of tracheae, it is characterized in that the suction port end of filter chamber is provided with a flow distribution plate, and the middle part is laid with micropore ceramic filter element.Black smoke particle entrained in the waste gas is filtered by ceramic element, and the waste gas of discharge is promptly comparatively clean, does not contain black smoke, effectively reduces the atmosphere smoke contamination.

The utlity model has reasonable in design, filter by discharge being contained the bigger waste gas of black smoke amount, the present situation of the black smoke of emerging when eliminating conventional diesel engine because of aging or open out reduces the pressure to environment, also improves quality of the life.

Description of drawings:

Below in conjunction with concrete legend the utility model is described further.

Embodiment:

See figures.1.and.2, the black diesel smoke particulate filter, comprise that one has into, steam outlet pipe 1,2 filter chamber 3, the suction port end of filter chamber 3 is provided with a flow distribution plate 4, the middle part is laid with micropore ceramic filter element 5, this example micropore ceramic filter element 5 is arranged at regular intervals by an end cecutiency tubular ceramic pipe 51 and is formed, form big wall stream interface, guarantee that waste gas does not influence the unimpeded of exhaust because of the existence of filter core 5, the interval that its two stoneware pipe is 51 is not more than ceramic caliber, and one can increase stoneware pipe 51 quantity increases throughput, and second stoneware pipe is used for exhaust at interval, exhaust without hindrance every, less clearance also is enough to.Filter chamber's 3 suction port ends are spiral cover 31 formula structures, can easily spiral cover 31 be screwed off and change filter core, and flow distribution plate 4 also is fixed on the spiral cover 31, make things convenient for processing and fabricating.Flow distribution plate 4 contain one with big extension tube 41 such as suction port, be closed with an end plate 42 at tube end, be evenly equipped with pore 43 on extension tube 41 and the end plate 42, air-flow can be evenly distributed on the filter core 5.This example ceramic element can be made the core body of band square through hole by pressing mold, then intersects at the adjacent through-holes two ends respectively and blocks up, and makes it become the blind pipe shape, and this production technology is comparatively simple, is easy to realize.

With reference to Fig. 3, this example provides different above-mentioned production method, makes the stoneware pipe 51 of blind pipe shape earlier, then stoneware pipe 51 is inserted admittedly in the same direction to form at baffle plate 52.

Filter of the present utility model can be installed in the front or rear end of baffler.
