Description
Technical field
The utility model relates to motor exhaust post-processing technology field, particularly relates to the filter element of the isobaric grain catcher of a kind of closed.
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) wall-flow type metal fiber 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, work and can block not possessing 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 or high-temperature control regeneration.
Model utility content
The purpose of this utility model is to provide the filter element of the isobaric grain catcher of a kind of closed, has that filter efficiency is high, the recovery time is short, and the feature of the trapping of particle stable homogeneous more in motor exhaust.
In order to achieve the above object, the technological scheme that the utility model provides is: the filter element of the isobaric grain catcher of a kind of closed, 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 and trough passage, described crest passage is provided with primary peak slanting baffle and secondary peak slanting baffle, corrugated metal sheet between described primary peak slanting baffle and secondary peak slanting baffle offers crest through hole, described trough passage is provided with the first trough slanting baffle and the second trough slanting baffle, corrugated metal sheet between described first trough slanting baffle and the second trough slanting baffle offers trough through hole, described primary peak slanting baffle is equal with the height of crest with the height of secondary peak slanting baffle, the height of described first trough slanting baffle and the second trough slanting baffle is equal with the height of trough.
Described crest passage and primary peak slanting baffle is integrally manufactured forms, described crest passage and secondary peak slanting baffle is integrally manufactured forms, described trough passage and the first trough slanting baffle is integrally manufactured forms, described trough passage and the second trough slanting baffle is integrally manufactured forms.
The beneficial effects of the utility model are: the utility model 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 and trough passage, described crest passage is provided with primary peak slanting baffle and secondary peak slanting baffle, corrugated metal sheet between described primary peak slanting baffle and secondary peak slanting baffle offers crest through hole, described trough passage is provided with the first trough slanting baffle and the second trough slanting baffle, corrugated metal sheet between described first trough slanting baffle and the second trough slanting baffle offers trough through hole, described primary peak slanting baffle is equal with the height of crest with the height of secondary peak slanting baffle, the height of described first trough slanting baffle and the second trough slanting baffle is equal with the height of trough.Thus reach the effect that filter efficiency is high, the recovery time is short, and the air pressure of the same degree of depth of filter element is equal, makes filter element to the trapping of particle in motor exhaust stable homogeneous more.
accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model.
Embodiment
Embodiment 1
As shown in Figure 1: the filter element of the isobaric grain catcher of a kind of closed, comprise filter element body 1, described filter element body 1 is formed by the identical corrugated metal sheet 2 of the number of plies and alloy fiber felt 3 successively alternate superimposed winding, described corrugated metal sheet 2 offers respectively crest passage 4 and trough passage 5, described crest passage 4 is provided with primary peak slanting baffle 6 and secondary peak slanting baffle 7, corrugated metal sheet 2 between described primary peak slanting baffle 6 and secondary peak slanting baffle 7 offers crest through hole 8, described trough passage 5 is provided with the first trough slanting baffle 9 and the second trough slanting baffle 10, corrugated metal sheet 2 between described first trough slanting baffle 9 and the second trough slanting baffle 10 offers trough through hole 11, described primary peak slanting baffle 6 is equal with the height of crest with the height of secondary peak slanting baffle 7, the height of described first trough slanting baffle 9 and the second trough slanting baffle 10 is equal with the height of trough.
Described crest passage 4 forms with primary peak slanting baffle 6 is integrally manufactured, described crest passage 4 forms with secondary peak slanting baffle 7 is integrally manufactured, described trough passage 5 and the first trough slanting baffle 9 is integrally manufactured forms, described trough passage 5 and the second trough slanting baffle 10 is integrally manufactured forms.
Thus reach the effect that filter efficiency is high, the recovery time is short, and the air pressure of the same degree of depth of filter element is equal, makes filter element to the trapping of particle in motor exhaust stable homogeneous more.
The working principle of the filter element of the isobaric grain catcher of a kind of closed:
Motor exhaust enters from this complete stifled formula grain catcher entry end, and flow through crest passage 4 or the trough passage 5 of corrugated metal sheet 2, and through alloy fiber felt 3 under the stop of primary peak slanting baffle 6 or the first trough slanting baffle 9, granular absorption in motor exhaust is on alloy fiber felt 3, motor exhaust is through the trough passage 5 or the crest passage 4 that flow through adjacent layer corrugated metal sheet 2 after alloy fiber felt 3, then under the stop of adjacent layer first trough slanting baffle 9 or primary peak slanting baffle 6 again through alloy fiber felt 3, thus make motor exhaust be transmitted back to next crest passage 4 or the trough passage 5 of original corrugated metal flaggy, motor exhaust simultaneously in crest passage 4 or trough passage 5 flows into adjacent crest passage 4 or trough passage 5 by crest through hole 8 or trough through hole 11, thus the air pressure reaching the motor exhaust of same depth location in filter element 1 is equal.Thus make the trapping stable homogeneous more of particle in filter element 1 pair of motor exhaust.Then motor exhaust repeats the outlet port that above-mentioned steps flow to the filter element of complete stifled formula grain catcher, and is flowed out by the outlet port of the filter element entirely blocking up formula grain catcher.
