Embodiment Construction

[0013] The specific implementation of the present invention will be further described below in conjunction with the accompanying drawings.

[0014] As shown in Fig. 1, Fig. 2 and Fig. 3, the present invention comprises an intake pipe 1, a metal shell 2, a small exhaust pipe 3, a main exhaust pipe 4, a gas collection chamber 5, a metal bracket 6, a metal filter screen 7, Insulator 8, high voltage DC power supply 9.

[0015] The metal shell 2 is a shell with an open top, a platform-shaped transition section on the left and right, and a cuboid in the middle. The two ends of the metal shell 2 are connected to the intake pipe 1 and the small exhaust pipe 3 respectively. The middle cuboid of the metal shell 2 is equipped with several filter units parallel to the axial direction. The filter unit is composed of a metal bracket 6 and a metal filter screen 7. The metal bracket 6 is a cuboid frame welded by metal strips. Cover the metal filter screen 7 on the two facades to the directio...

Abstract

The invention relates to a kind of filter for the diesel motor exhausting carbon-smoke particles. It includes metal shell, filter unit covered with metal filter screen on metal shelf, high-pressure direct current power, intake pipe, small blast pipe and main blast pipe. The adjoint filter units are in electrical connection with the two poles of the high-pressure direct current power, the filter unit is fixed in the metal shell through insulator. The clean gas filtrated through metal filter is discharged through gas collecting room, theo ther gas which can be twice filtered and circulated enter into air cylinder to burn and the carbon-smoke particles with electricity is discharged by small blast pipe. The characteristic of the device is that it divides the smoke gas into clean gas and high carbon-smoke density gas, the filtering can go on in succession, it won't get plugged, needn't regenerate, and has long performance life.

Description

technical field [0001] The invention relates to a diesel engine exhaust purification device, in particular to a diesel engine exhaust soot particle filtering device. The utility model belongs to the technical field of power machinery and environmental protection. Background technique [0002] Diesel engine exhaust soot particles contain a variety of substances that are harmful to the human body and cause serious pollution to the environment. Exhaust and smoke elimination devices in the prior art mainly contain the following types: [0003] One is media filtration, and then the filter material is regenerated. The diesel engine exhaust particle processor with the patent application number 99250866.5 uses ceramics to filter, and intermittently uses microwaves to burn and regenerate the soot deposited in the ceramics. This arrangement can cause clogging of the filter media. The patent application number is 00243230.7, which is a soot filter for reverse jet regeneration diese...
