Diesel engine particle catcher

Abstract

The present invention involves the post-processor technology of diesel engine, particularly relates to a detachable diesel engine particle drip catcher. It consists of shell, filter element, pressure sensor, control unit and display device. Said shell uses separated shell and bolts (7) precompact connection, the filter element (6) is removable, filling materials are filled between the middle press plate (4)of shell and filter element (6), the partitioned particle drip catcher shell is divided into shell (2) and filter element (6) which are filled with filling materials between them, the two ends (2) of shell are tail gas input and output mouth, pressure sensor (1) is installed on the two ends of shell and connected with control unit (8), display device (9) is connected on the control unit (8). The invention aims at particle in different diameters in diesel engine, staged-filters and traps in order to improve the filtering effect, reduce trap device blocking up, prolong its regeneration cycle and retarding aging speed of filter elements, it improves the use life of particulate trap device.

Description

technical field [0001] The invention relates to the technical field of post-processors of diesel engines, in particular to a detachable diesel engine particulate trap. technical background [0002] Diesel engines are widely used in various fields of the national economy due to their high thermal efficiency, good fuel economy, large low-speed torque, long service life and low maintenance costs. However, a large number of particulates contained in diesel exhaust emissions endanger human health and pollute the environment on which human beings live. Therefore, increasingly strict vehicle emission regulations have imposed stricter restrictions on them. At present, the measures of improving diesel quality and internal purification can no longer meet the requirements of more stringent emission regulations. Particulate capture technology as an external purification has become the most effective measure to reduce diesel particulate emissions and has the best commercial prospects. T...

However, a large number of particles contained in diesel exhaust emissions endanger human health and pollute the environment on which human beings live. For this reason, increasingly strict vehicle emission regulations have imposed stricter restrictions on them

At present, the measures of improving diesel quality and internal purification can no longer meet the requirements of more stringent emission regulations. Particulate capture technology as an external purification has become the most effective measure to reduce diesel particulate emissions and has the best commercial prospects. Technology

However, the diameters of the particles emitted by diesel engines have a wide range of distributions, and particles of different diameters have different effects on human health. It is difficult for a particle filter with a single pore size to capture different particle sizes, resulting in low capture efficiency of the particle filter , Short service life and frequent regeneration times make the diesel engine have to install an additional regeneration device

However, the limited vehicle layout space and on-board energy make it difficult for the volume and power of the regenerative device to reach the ideal state, resulting in incomplete regeneration, frequent regenerations, and aging and failure of the filter element of the particulate filter; in addition, the on-board regenerative device not only It consumes on-board energy, increases the cost of the vehicle, and also causes a waste of resources
