Abstract
The invention discloses a filter element of a full-closed type particle trap and a use method. The filter element comprises a filter element body which is formed by alternately laminating and winding the same layers of corrugated metal plates and alloy fiber felts in sequence; a peak channel and a trough channel are formed in the corrugated metal plates respectively; a peak baffle plate is mounted on the peak channel; a trough baffle plate is mounted on the trough channel; the height of the peak baffle plate is equal to that of the peak; the height of the trough baffle plate is equal to that of the trough. The distances between the peak baffle plate and the adjacent trough baffle plates are equal, so that the filtering efficiency is high, and the regeneration time is short.
Description
Technical field
The present invention relates to motor exhaust post-processing technology field, particularly relate to a kind of filter element and using method of closed grain catcher.
Background technique
Be widely used in the motor of automobile, engineering machinery, farm machinery, train traction locomotive and boats and ships at present, give off a large amount of particulate matters at work, not only serious harm is caused to health, and serious pollution is caused to environment.For this reason, industry drops into engine particulate matter post-processing technology and the product that a large amount of manpower and materials work out various mode, and huge contribution has been made in the lifting for engine emission levels.Summarize existing engine particulate matter post-processing technology and product, can be divided into two aspects, one is the trapping of particulate matter, and two is the regeneration of particulate matter.
In the trapping of particulate matter, existing technology and product and feature as follows:
1) wall-flow ceramic filter filter efficiency is very high, high temperature resistance good, but poor air permeability, fluid-pressure drop are large, resistance to mechanical vibratility is poor, thermal-shock resistance is poor, do not possessing the easily blocking that to work under regeneration condition, duct is once blocking, exhaust back pressure is very high, affect motor to work on, need artificial off-line to clear up.
2) metal fiber filter of other type, as pocket type, tubular type or pleat page type filter, filter efficiency compared with high, good permeability, fluid-pressure drop is little, resistance to mechanical vibratility is strong, thermal-shock resistance good, but high temperature resistance is poor, although not easily block not possessing to work under regeneration condition, but the too thick exhaust back pressure that also can cause of carbon is very high, affects motor and works on.Except this, the filter area of the type filter unit volume is little, cause filter volume large, occupy the larger space of vehicle, application is inconvenient.
3) part flow filter, as metallic foam filter, wire gauze filter, staggered form steel fiber corrugated sheet filter, corrugated metal sheet support flow guide type metal fiber filter etc.Such filter is preventing having obvious advantage in plugged filter, but also Shortcomings, as filter efficiency is lower, the discharge that general motor installs rear particulate matter additional makes moderate progress, but does not reach the requirement of high standard emission level.
Summary of the invention
The object of the present invention is to provide a kind of filter element and using method of closed grain catcher, have arresting efficiency high, mechanical strength is good, and reproduction speed is fast, the feature that filter efficiency is high.
In order to achieve the above object, technological scheme provided by the invention is: a kind of filter element of closed grain catcher, comprise filter element body, described filter element body is formed by the identical corrugated metal sheet of the number of plies and alloy fiber felt successively alternate superimposed winding, described corrugated metal sheet offers respectively crest passage 4 and trough passage, described crest passage is provided with crest plate washer, described trough passage is provided with trough plate washer, the height of described crest plate washer is equal with the height of crest, and the height of described trough plate washer is equal with the height of trough.
Distance between described crest plate washer to adjacent trough plate washer is equal.
A using method for the filter element of closed grain catcher, comprises the following steps:
Motor exhaust enters from this complete stifled formula grain catcher filter element entry end, and flow through crest passage or the trough passage of corrugated metal sheet, and through alloy fiber felt under the stop of crest plate washer or trough plate washer, granular absorption in motor exhaust is on alloy fiber felt, motor exhaust is through the crest passage or the trough passage that flow through adjacent layer corrugated metal sheet after alloy fiber felt, then under the stop of adjacent layer trough plate washer or crest plate washer again through alloy fiber felt, motor exhaust is transmitted back to next crest passage or the trough passage of original layer, motor exhaust repeats the filter element outlet port that above-mentioned steps flow to complete stifled formula grain catcher, and flowed out by the filter element outlet port entirely blocking up formula grain catcher.
The invention has the beneficial effects as follows: the present invention is by comprising filter element body, described filter element body is formed by the identical corrugated metal sheet of the number of plies and alloy fiber felt successively alternate superimposed winding, described corrugated metal sheet offers respectively crest passage 4 and trough passage, described crest passage is provided with crest plate washer, described trough passage is provided with trough plate washer, the height of described crest plate washer is equal with the height of crest, and the height of described trough plate washer is equal with the height of trough.Distance between described crest plate washer to adjacent trough plate washer is equal.Thus it is high to reach arresting efficiency, mechanical strength is good, and reproduction speed is fast, the effect that filter efficiency is high.
accompanying drawing illustrates:
