Abstract

The invention belongs to the technical field of automobile exhaust purification, and discloses a high-efficiency automobile exhaust catalytic converter capable of real-time monitoring, including a casing and a purification component fixed in the casing, and at least two airflow velocity detection devices are installed in the casing , the purification assembly includes a detachable filter plate and a rotatable purification device, and at least one purification device is provided; the purification device and the air flow velocity detection device are distributed alternately, and are all located on the front side of the filter plate; A filter hole is provided in the purification device, and the filter hole includes a guide part and a connecting part; in summary, the present invention sets the purification device as a rotatable structure, and cooperates with the air flow velocity detection device to detect the air flow velocity on both sides , when the flow velocity difference on both sides exceeds the threshold value, the purification device is rotated to realize the self-cleaning of the purification device, so as to ensure that the overall purifier always has the effect of efficiently purifying exhaust gas, with simple structure, low cost and long service life.

Description

technical field [0001] The invention belongs to the technical field of automobile exhaust purification, and in particular relates to a high-efficiency automobile exhaust catalytic converter capable of real-time monitoring. Background technique [0002] In the field of automobile exhaust purification, the commonly used purifier is a three-way catalytic purifier. The working principle of this purifier is to convert harmful gases such as CO, HC and NOx emitted from automobile exhaust into harmless gases through oxidation and reduction. Carbon dioxide, water and nitrogen, so as to effectively realize the catalytic purification of harmful substances in automobile exhaust. [0003] However, the biggest disadvantage of existing three-way catalytic converters in use is that the catalytic efficiency is not high, especially on cars that have been used for a certain number of years. The factors that specifically affect the catalytic efficiency of three-way catalytic converters are: thr...

[0003] However, the biggest disadvantage of existing three-way catalytic converters in use is that the catalytic efficiency is not high, especially on cars that have been used for a certain number of years. The factors that specifically affect the catalytic efficiency of three-way catalytic converters are: three-way catalytic purification The internal structure of the device adopts a mesh or porous form, and when the car is discharging exhaust gas, the exhaust gas emitted not only contains harmful gases, but also contains a certain amount of solid particle pollutants. After the exhaust gas passes through the three-way catalytic converter During catalytic purification, the solid particle pollutants contained in the exhaust gas are also intercepted, thus adhering to the mesh of the three-way catalytic converter, causing the mesh to be clogged. It is getting more and more serious, greatly affecting the catalytic purification effect of the purifier

[0004] In addition, in the clogged state mentioned above, according to the exhaust direction of the exhaust gas, the structure at the intake end of the purifier is more obvious. There is still a certain distance, so the difficulty of cleaning and maintenance is greatly increased during the maintenance of the purifier. If the purifier is directly replaced, there will be a problem of high maintenance costs, and the structure close to the gas outlet in the purifier is less blocked, so it can be replaced directly It also causes a certain degree of waste of resources.
