Problems solved by technology
It is easy to accumulate a large amount of particles or sludge at the bottom entrance or the bottom layer, and it is easy to form blockage or uneven distribution of particles and sludge on each layer of filter screens. The particles and sludge accumulated in the bottom filter screen are much more than the upper filter screen. When the filter at the bottom is full of clogs, the upper filter is not fully utilized, which is not conducive to fire cleaning of spontaneous regeneration, dynamic regeneration and maintenance regeneration

Embodiment Construction
[0031] figure 1 The external structure of the particle trap of the present invention is shown. Four connecting pieces 43 extend from the front end of the housing 5 of the particle trap 1, and the angle between the four connecting pieces 43 is 90 degrees. Near the end of the sheet 43, a rotatable knocker 6 is provided. The knocker 6 includes a rotating shaft 61 and a gear 62 fixedly sleeved on the rotating shaft 61. The teeth of the gear 62 can contact the end of the connecting sheet 43. part, after being rotated, the end part can be knocked continuously to transmit vibration from the outside to the housing. The number and distribution position of the knocking parts 6 are adapted to the connecting pieces 43, which are also four, and they are close to each other. The end of the connecting piece 43, the connecting piece 43 is preferably iron sheet, steel sheet or other alloy sheet with good elasticity and resistance to high temperature of 600 degrees and corresponding combustion ...

The invention relates to the technical field of tail gas treatment, and discloses a method for separating particles in gas in a filter element assembly of a particle trap and the particle trap. The gas flows into the air inlet of the particle filter (1), passes through the filter screen (2) and the rear filter element (3) in the casing (5), and is discharged from the exhaust port of the particle filter (1) , particles or sludge are dispersed by a flow guide device (4) along with the gas in the air inlet, and flow in multiple directions towards the corresponding filter screens (2) located in multiple directions. There is a middle part of the flow guide device (4). A tip composed of multiple angled smooth inclined surfaces or a curved convex part formed by a smooth monolithic hemispherical shell, the particles or sludge in the gas in the middle of the air inlet are scattered by the tip or the convex part. The invention can fully use the filter screen before the trap is blocked, and when it is applied to the diesel engine particulate trap, it can cooperate with spontaneous regeneration, dynamic regeneration and maintenance regeneration to fully burn the particulate matter or oil sludge.
Description
technical field [0001] The invention relates to the technical field of polluted gas treatment, in particular to a method for separating particles in gas in a filter element assembly of a particle trap. , is discharged from the exhaust port of the particle filter, and the particles or sludge in the gas are separated by the filter screen and the post-filter element. [0002] The present invention also relates to the particle trap used in the method for separating particles in the gas in the filter element assembly of the particle trap, which includes a housing, a filter screen and a rear filter arranged in sequence from the air inlet to the exhaust port of the housing. Set the filter element. Background technique [0003] The filter element assembly in the particle filter in the prior art often has the problem of insufficient use of the filter screen, resulting in less separation of particulate matter in the gas, but it can also cause blockage of the filter element assembly o...
