Three-way catalyst detecting and cleaning device

Abstract

The invention discloses a three-way catalyst detecting and cleaning device which comprises an upper shell. The upper shell is fixedly connected with a left supporting plate, the upper shell is fixedly connected with a right supporting plate, the upper shell is fixedly connected with a lower shell, the left supporting plate is fixedly connected with a water outlet pipe, the water outlet pipe is fixedly connected with the left supporting plate, and the lower shell is connected with a valve spring. The valve spring is fixedly connected with a valve sliding block, the valve sliding block is connected with the lower shell in a sliding mode, and the valve sliding block is connected with a pull rod sliding block in a sliding mode. According to the three-way catalyst detecting and cleaning device, detection of the blockage condition of a three-way catalyst and triggering of the device are achieved through a pressure detecting mechanism and a switch locking mechanism, so that a cleaning agent can be added in time when the three-way catalyst needs to be cleaned; and meanwhile, a rotary cleaning device arranged in the device can conduct rotary cleaning through the air pressure difference provided by tail gas, the cleaning effect is improved, and it is guaranteed that a cleaning agent is fully utilized.

Description

technical field [0001] The invention relates to the related technical field of automobile exhaust purification, in particular to a detection and cleaning device for a three-way catalytic converter. Background technique [0002] The three-way catalytic converter is the most important external purification device installed in the automobile exhaust system. It can convert harmful gases such as CO, HC and NOx emitted from automobile exhaust into harmless carbon dioxide, water and nitrogen through oxidation and reduction. , the three-way catalytic converter is easy to be blocked by oxide particles formed in the engine after being used for a period of time, which affects its conversion efficiency, and needs to be cleaned, but because the three-way catalytic converter is difficult to disassemble, cleaning is often difficult, and the cleaning agent needs to pass Fuel tank is added, and the cleaning operation is cumbersome. At the same time, it is difficult to observe the use of the ...

[0002] The three-way catalytic converter is the most important external purification device installed in the automobile exhaust system. It can convert harmful gases such as CO, HC and NOx emitted from automobile exhaust into harmless carbon dioxide, water and nitrogen through oxidation and reduction. , the three-way catalytic converter is easy to be blocked by oxide particles formed in the engine after being used for a period of time, which affects its conversion efficiency, and needs to be cleaned, but because the three-way catalytic converter is difficult to disassemble, cleaning is often difficult, and the cleaning agent needs to pass Fuel tank is added, and the cleaning operation is cumbersome. At the same time, it is difficult to observe the use of the three-way catalytic converter, and the cleaning agent can only be added frequently and regularly, so it is easy to cause waste. In view of the above shortcomings, the present invention has improved
