Abstract
The utility model relates to a honeycomb metal carrier, which is composed of a cylinder body, a shim plate and a corrugated plate. The corrugated plate and the shim plate are curled into a core body after overlapped, and the core body is arranged in the metal cylinder body. The mutual contact part between the shim plate and the corrugated plate and the mutual contact part between the outer ring of the core body and the inner wall of the cylinder body adopt brazing connection. With large geometric surface area and high catalyzing efficiency, the utility model can obviously reduce the sewage discharging quantity of the tail gas of motor vehicle. With small exhaust resistance, the utility model can increase the output power of an engine and reduce the oil consumption. The heat capacity is low, and the start ignition is rapid. The exhaust pollution of the cold starting is reduced, and the mechanical endurance, the vibration resistance and the thermal shock resistance are good. The utility model is the preferred carrier of the tail gas purification of the motor vehicle, especially the catalytic converters of motorcycles and power-assisted bicycles.
Description
The utility model belongs to the motor-vehicle tail-gas catalyst, is specifically related to a kind of honeycomb metal carrier.
In the purifying vehicle exhaust gas system, pottery and metal two classes are arranged at present as the carrier of catalyst.Because ceramic monolith is little with respect to the metallic carrier geometrical surface, thermal conductivity is low, thermal capacity is high, vibration resistance is poor, under equal efficient, the converter volume is big, and it is big to take up room.So the advantage of metallic carrier is many than ceramic monolith.
Existing in the market metallic carrier has two kinds of forms, and a kind of is that core body adopts wire gaze, and it is to utilize " one " word or " ten " word or " bifurcation " word carriage anchoring filament web-roll core body.When air communication is crossed the wire gaze core body, easily, cause back pressure to increase at the bigger turbulent flow of the inner formation of core body, engine operating condition is changed, disposal of pollutants increases; And utilize fixedly core body of " one " word or " ten " word or " bifurcation " word carriage, and the geometric jacquard patterning unit surface utilization ratio is low, and mechanical endurance is poor, causes the catalyst conversion ratio to reduce, and working life is short; Another kind is to adopt sheetmetal to make core body, and it vertically is through-type passage, and air-flow is short in the carrier inside waiting time, and conversion ratio is influenced.
The honeycomb metal carrier that the purpose of this utility model provides that a kind of geometric jacquard patterning unit surface utilization ratio height, air-flow are long in the carrier inside waiting time, mechanical endurance can be good, back pressure is low.
Technical solution of the present utility model is: the honeycomb metal carrier is made up of cylindrical shell, backing plate and corrugated sheet, is wound into core body after corrugated sheet and backing plate are overlapping, and core body is placed in the metal cylinder; Backing plate and corrugated sheet are in contact with one another part and core body cylindrical and are in contact with one another part employing soldering with cylinder inboard wall and are connected; Be provided with the hole on above-mentioned backing plate and corrugated sheet or backing plate or the corrugated sheet.
Further describe the utility model below in conjunction with accompanying drawing:
Fig. 1 is a honeycomb metal carrier cross-sectional structure schematic representation;
Fig. 2 is a honeycomb metal carrier longitudinal sectional view.
Wherein: 1, cylindrical shell 2, core body 3, corrugated sheet 4, backing plate 5, hole
As shown in Figure 1 and Figure 2, the core body 2 of the utility model honeycomb metal carrier adopts the Stainless Steel Band of 0.03～0.08mm to make, and wherein corrugated sheet 3 is reeled with backing plate 4 overlapping backs and made core body 2, and core body is placed in the metal cylinder 1.In order to prevent core body play in cylindrical shell, the utility model adopts the method for vacuum brazing, backing plate 4 and corrugated sheet 3 is in contact with one another part and core body 2 cylindricals is in contact with one another partly with cylindrical shell 1 inwall and links together.The core body that above-mentioned corrugated sheet and backing plate are formed is some passages vertically, is parallel to each other between each passage; The core body cross section is cellular pass.
For making air-flow longer in the carrier inside waiting time, the utility model is provided with hole 5 on backing plate and corrugated sheet or backing plate or corrugated sheet, and hole shape can be circular, square, long hole shape etc.Above-mentioned hole forms some and the axial vertical passage of core body in the overlapping back of corrugated sheet and backing plate.
The utility model adopts metal steel band as thin as a wafer to make core body, can form bigger geometrical surface, thereby improve catalytic efficiency, significantly reduces the motor-vehicle tail-gas blowdown flow rate; Exhaust resistance is little, can reduce the pressure loss greatly, improves the output power of motor, reduces oil consumption.
The utility model thermal capacity is low, can reach required operating temperature at short notice, and can make electric heating type, makes catalyzer open combustion fast, reduces cold start emission and pollutes; Mechanical endurance, vibration resistance and thermal-shock resistance are good, long service life.Be current mobility tail gas purification, the especially first-selected carrier of the catalyst of motorcycle, booster car.
