Abstract
The utility model discloses a catalytic converter structure used for an exhaust manifold. The catalytic converter structure comprises a cylindrical shell and a carrier which is arranged inside the shell, wherein a heat-insulating layer and a flame-resistant layer are arranged between the carrier and the shell, and the heat-insulating layer is located between the flame-resistant layer and the carrier. By adopting the structure disclosed by the utility model, damages brought by overheat of the catalytic converter or even autoignition to the catalytic converter can be avoided, so that the service life of the catalytic converter is prolonged.
Description
Technical field
The utility model relates to automobile technical field, specifically for the catalyst converter structure of gas exhaust manifold.
Background technique
Catalyst converter, be mounted in most important outer purifier in automobile exhaust system, and the harmful gases such as CO, the HC that it can be discharged vehicle exhaust and NOx change harmless carbon dioxide, water and nitrogen into by oxidation and reduction.When the vehicle exhaust of high temperature passes through purification plant, purifying agent in catalyst converter will strengthen the activity of CO, HC and tri-kinds of gases of NOx, impel it to carry out certain oxidation-reduction chemical reaction, wherein CO at high temperature is oxidized into colourless, nontoxic carbon dioxide; The HC compound at high temperature is oxidized to water (H20) and carbon dioxide; NOx is reduced into nitrogen and oxygen.Three kinds of harmful gases become innocuous gas, and vehicle exhaust is purified.
Catalyst converter generally comprise shell, carrier and be arranged on shell and carrier between thermal-protective coating, usually thermal-protective coating is the asbestos fiber felt, because catalyst converter in use oxidation-reduction reaction can occur, and temperature is relatively high, when oxygen concentration and temperature when suitable, combustion phenomena easily occurs, and brings certain potential safety hazard.
The model utility content
The utility model provides the catalyst converter structure for gas exhaust manifold, has solved in the past catalyst converter when oxidation-reduction reaction, because temperature is relatively high, when oxygen concentration and temperature, when suitable, combustion phenomena easily occurs, and brings certain security hidden trouble.
The utility model is that the technical solution problem is achieved through the following technical solutions: for the catalyst converter structure of gas exhaust manifold, comprise shell cylindraceous and carrier in the enclosure is set, be provided with thermal-protective coating and flame-retardant layer between described carrier and shell, described thermal-protective coating is between flame-retardant layer and carrier.In the time of work, spray catalyzer on carrier, as platinum, rhodium, palladium etc., thereby form purifying agent, the harmful gases such as CO, HC and NOx are carried out to purified treatment.
Further, described carrier is honeycomb ceramic carrier, and carrier be shaped as cylindrical.The ceramic honey comb specific surface area is large, thermal capacity is large, thermal coefficient of expansion is little, corrosion-resistant strong, resistance to heat is good, the industry such as ceramic honey comb is applied to chemical industry, controls gold, combustion gas, environmental protection.
Further, the height of described carrier is less than the height of shell 1.
Further, the thickness of described thermal-protective coating is 0.3 ~ 1mm.
Further, the thickness of described flame-retardant layer is 0.5 ~ 2mm.
Further, described thermal-protective coating and flame-retardant layer are cylindric, and the height of thermal-protective coating and flame-retardant layer is equal to or greater than the height of carrier.
The utility model compared with prior art has the following advantages and beneficial effect: the utility model by arranging thermal-protective coating and flame-retardant layer between carrier and shell, can prevent that catalyst converter is overheated, or even spontaneous combustion brings damage to catalyst converter, thereby improved the working life of catalyst converter.
