Abstract
The utility model discloses a clarifier for car waste gas which is used for governing car waste gas. Only one layer of alloying honeycomb catalyst is loaded in an inner cylinder of the utility model in radial direction. A roll-type smoke stopping block is arranged at the front of the catalyst, an overtemperature protection device is arranged on an air inlet pipe, and a flow stopping frame is arranged between the rear end face of the catalyst and the rear end cover of a clarifier. When an engine igniting system failures or the waste discharging concentration overtops, the catalyst can not be burnt, and the engine is nor overheated. The number of the anterior and rear end faces of the catalyst are more balanced, the utilizing rate is high, and the requirement of sealing for the inner cylinder is lower. The utility model has the advantages of simple structure and convenient installation, if the clarifier for car waste gas is combined with a common car silencer, the noise eliminating effect is also capable of being improved.
Description
Car exhaust gas purifier is used for automobile exhaust gas and administers.
General car exhaust gas purifier has the noise elimination effect concurrently, it by suction tude, in be equipped with that segmentation is placed and the inner core of the alloy honeycomb catalyst that separates with dividing plate, form with the urceolus and the tail pipe of interior pipe coaxial line, catalyzer in the inner core divides the innner and outer two-layer along radial direction, the nexine catalyzer directly communicates with suction tude, its detailed structure is asked for an interview bulletin on July 30th, 1986, and application number is 85202176 Chinese utility model patent " two cylinder type automobile exhaust gas purifying silencing apparatus ".In this structure, the waste gas sent off from automobiles that is heated by catalysis, can be by dividing the catalysis silencer element of four sections placements, around the Returning reactor inlet, the gas that enters reactor risen give heat effect, simultaneously in flow process, also improve the temperature of catalyst layer, thereby improved catalyticing purifying effect.When outwards discharging,, just can utilize the waste heat of exhaust that catalyst layer is incubated, thereby save thermal insulating material, also reduce cost owing to formed a cavity between the inside and outside tube.The shortcoming of this structure is, when the automobile blowdown was too much, catalytic reaction heat also correspondingly increased greatly, if when the temperature of the gas that discharges after the catalytic reaction surpasses 1100 ℃, will burn catalyzer; In addition, air-flow is a three-decker, and is higher to the welding requirements of inner core and suction port, and gas leakage is arranged slightly, and purification ratio will descend significantly; Its diameter dimension is also excessive, is difficult for installing.The utility model can overcome this shortcoming; it is characterized in that: one deck catalyzer radially only is housed in the inner core and blocks the cigarette piece and block the air guide sleeve that the cigarette piece joins and directly link to each other with suction tude by what separate with dividing plate; on the tube wall of suction tude, along the circumferential direction have overheated exhausting waste gas hole; on tube wall, be with the overtemperature protection ring that red copper is made, the choked flow frame is housed between tail pipe and catalyzer.Above the said cigarette piece that blocks be to roll by two thickness, surface that width is all identical that modulus is arranged is that the oblique ripple length of 3 miter angle is with peaceful tape wrapping to form.The choked flow frame then is made up of with weldering support thereon a microperforated panel that is round shape with the tail pipe coaxial line.
In the general exhaust purifier, air-flow is a three-decker, and in the utility model, air-flow is one deck structure; Air-flow enters the mouth from suction tude, flows through the aperture in the catalyzer equably by blocking the cigarette piece, after the choked flow frame discharge by tail pipe, rely on the heat-preservation cotton between the inside and outside tube to be incubated to improve catalytic effect, thereby simplified production technology, and having reduced requirement to sealing, cost has also correspondingly reduced.Main is to be, general exhaust purifier breaks down or during automobile blowdown excessive concentration, the high temperature of generation can be lighted remaining inflammable matter in the waste gas and catch fire, and catalyzer is burnt out at engine igniting system, causes exhaust to stop up engine overheat.The utility model has increased an overtemperature protection ring made from copper plate, and its fusing point is 750 ℃.When above-mentioned fault occurring; high-temp waste gas at first by overheated exhausting waste gas hole with overtemperature protection ring fusing, gas is directly discharged from this hole, make that catalyzer is unlikely to be burnt out; send the noise that is higher than tens of times of former exhaust sound simultaneously and report to the police, notify the driver in time to get rid of so hinder.
In order to remove the inflammable matter in the waste gas, general adorned in the suction port back one play the dedusting effect block the cigarette piece.It by two thickness, width all identical, above roll that the long band of the oblique ripple that miter angle is arranged is folded mutually to form, when folded mutually, the oblique ripple angle on its adjacent two bands must be opposite, its ripple becomes miter angle with transverse axis, its adjacent then must become 135 ° of angles.The surface that the heavier soot dust granule in the exhaust or inflammable matter can be trapped in belt so just.But the shortcoming of this structure is: its airspeed is successively decreased around the middle mind-set, and the aperture of catalyzer is parallel to center line, thereby the suffered load of catalyzer that is positioned at the center portion is higher than the edge far away, makes catalyst action unbalanced.Of the present utility modelly block the cigarette piece owing to be to form with long band of the oblique ripple of 45 and flat rubber belting coiling, in blocking the cigarette piece, form many little ducts along center hole rotation tilt fixing, thereby when exhaust enter block the cigarette piece after, also formed swirling eddy, but flow velocity is just gas can be uniformly distributed in catalyst surface uniformly like this to make its load be tending towards balanced everywhere.
In general cylinder type exhaust purifier, relief opening is positioned at the center portion, and its vapour lock is partly lower than other, thereby its flow velocity is just corresponding high, and the surface loading on the catalyzer ear end face is also unbalanced like this.Relief opening of the present utility model and suction port are not positioned on same the center line, and be provided with the microperforated panel of a circle at the relief opening position, vapour lock with suitable increase relief opening center portion, force a part of gas to shunting all around, make the load of catalyzer comparatively balanced, simultaneously because air inlet and relief opening not on same center line and loaded onto microperforated panel again, thereby have played certain noise elimination effect.This piece microperforated panel is welded with support every place, 90 ° of angles on circumference, formed a choked flow frame, so that make between the rear end cover of its ear end face that can be fixed on catalyzer and purifier.In order further to reduce noise, the utility model also needs to connect in addition a general automotive muffler again.
