Abstract
The utility model discloses a purifying muffler for the exhaust discharged by an automobile and various internal combustion engines. The utility model comprises one to three purifying sound muffling chambers, one to three buffer chambers and a sound muffling chamber, all of which build a combination of one to three grades purifying, one to three grades buffering and two to four grades muffling. The purifying sound muffling chamber is provided with grainy platinum metal catalysts inside, and the sound muffling chamber is a porous sheath pipe combined type sound muffling chamber. The purifying muffler has an average 94.25% purifying rate on carbon monoxide (CO), and an average 60% purifying rate on hydrocarbon (CH). The noise of the utility model is 66 decibels (db), and once charged with material, the purifying muffler can be used for three years and can be regenerated to use later with a total life of 49, 000 hours.
Description
The invention belongs to discharge of noxious gases purification, noise elimination field, it is a kind of purification, silencer that is applicable to automobile and various exhaust emissions from internal combustion engines.
Because contain carbon monoxide (CO), hydrocarbon harmful gases such as (CH) in the exhaust emissions from internal combustion engines, atmosphere is subjected to severe contamination, noise exceeds standard, and directly has influence on the healthy of the masses.
It is still undesirable that prior art purifies the effect of eliminating the noise, Chinese patent CN85204585 adopts secondary purification, secondary to eliminate the noise, make catalyzer with rare earths material, purification, noise elimination have certain effect, but do not reach NBS, and rare earths material at high temperature burns and can produce a kind of strong foul smell, and environment is still had contamination.
The present invention's purpose is to provide a kind of raising carbon monoxide and hydrocarbon purification ratio, reduces the device of noise figure.Adopt 1-3 purification anechoic room, a 1-3 buffer cell and an anechoic room to be combined into the combination that the 1-3 level purifies, the 1-3 level cushions and the 2-4 level is eliminated the noise.Purify between the anechoic room and purify between anechoic room and the anechoic room and keep certain distance, the space of formation buffer cell.Purify in the anechoic room the 871 type platinum metal catalyst that diameter is the 3-8 millimeter are housed.This model platinum metal catalyst is used for apparatus of the present invention, its activity and excellent thermal stability, purifying effect surpasses discharging standards, the average purification ratio 94.25% of carbon monoxide (CO), the average purification ratio 60% of hydrocarbon (CH), noise drops to 66 decibels (db).This kind catalyzer used after 7000 hours, re-used 7000 hours after can regenerating, and terminal life can reach 49,000 hours, improved several times than prior art.
Existing accompanying drawings is as follows:
Accompanying drawing 1 purifying muffler structural drawing
(1) suction tude, (2) front cover, (3) housing, (4) stephanoporate round tube, (5) platinum metal catalyst, (6) preceding dividing plate, (7) buffer cell, (8) weld seam, (9) annular oriffice, (10) sleeve pipe, (11) sleeve pipe, (12) sleeve pipe, (13) rear end cover, (14) conical tube, (15) rear bulkhead, (16) charging pipe, (17) conical tube.
Described purification anechoic room first Room (air inlet is to the exhaust order) comprises housing (3), and by stephanoporate round tube (4) concentric porous conical tube of suit (17) and front shroud (2), rear bulkhead (15), charging pipe (16) are welded into a whole; Purify anechoic room second Room and comprise housing (3), dividing plate (6), rear bulkhead (15), charging pipe (16) are welded into a whole before being reached by stephanoporate round tube (4) the concentric porous conical tube of suit (14).
Described anechoic room is positioned at the end that purifies anechoic room, comprises housing (3), and by stephanoporate round tube (10), (11) (12) are welded into a whole with annular slab (9), rear end cover (13).
The center line that purifies anechoic room, anechoic room and suction tude (1), sleeve pipe (12) (outlet pipe) coincide, and its end face macropore is over against suction tude (1).Purify between the anechoic room, keep certain distance between purification anechoic room and the anechoic room, form the space of a buffer cell.
The waste gas that internal-combustion engine is discharged enters first by suction tude and purifies anechoic room conical tube (17), because rear bulkhead sealing, air-flow can only enter from the conical tube aperture, under the platinum metal catalyst effect, carbon monoxide in the waste gas becomes carbon dioxide, and hydrocarbon becomes water and carbon dioxide, and oxynitrides then becomes nitrogen and oxygen, enter first buffer cell through stephanoporate round tube (4) aperture along housing (2) inwall, noise is also subdued through one-level.Similar first purifies anechoic room, waste gas purifies anechoic room through second and enters second buffer cell, enter anechoic room sleeve pipe (10) after being subjected to secondary purification and eliminating the noise, (11), (12), through the third level last discharge of eliminating the noise, harmful gas content carbon monoxide is lower than 0.5%, hydrocarbon be lower than 500PPM(1,000,000/).
Charging pipe by a plug screw sealing, was once feeded available 3 years after charging.
Accompanying drawing 2 purifying muffler modification structures figure
(1) first purifies anechoic room, (2) first buffer cells, and (3) second purify anechoic room, (4) second buffer cells, (5) the 3rd purify anechoic room, (6) the 3rd buffer cells, (7) anechoic room.
The first purification anechoic room and Fig. 1 are roughly the same, second, third purifies anechoic room is that porous slab and housing weld and fill up the cylindrical body of granular platinum metal catalyst, anechoic room is a porous conical tube and two the stephanoporate round tube suits that comprise housing, and constitutes an integral body with porous plectane, rear end cover welding.This design is applicable to that high-powered engine uses.
Must be pointed out, the present invention includes all modification of utilizing the design's thought.
