Problems solved by technology

[0003] Due to the high content of sulfur, phosphorus and olefins in the gasoline used, the three-way purifier is generally scrapped after the car has driven 80,000 to 100,000 kilometers. The failure of the three-way catalytic converter carrier will convert toxic gases such as CO, CH and NO into non-toxic Insufficient gas will not only increase the exhaust volume of the vehicle and aggravate the pollution to the environment, causing the exhaust emission of the vehicle to fail to meet the standard, but also block the three-way catalytic converter and affect the power of the car, resulting in insufficient power of the car and increasing the fuel consumption of the car

Embodiment 1

[0023] Such as figure 1 Shown: a three-way catalytic converter regeneration treatment device, including a casing (not shown in the figure), which is equipped with a water tank 1, a water tank 2, a cleaning pump 3, a controller (not shown in the figure), a connection The pipeline 5, the three-way catalytic converter water inlet joint 6 and the three-way catalytic converter water outlet joint 7, the water tank 1 and the chemical tank 2 are respectively connected to the cleaning pump 3, and the cleaning pump 3 is also connected to the three-way catalytic converter water inlet joint 6, the three-way catalytic converter The catalytic converter water inlet joint 6 is used to connect the gas outlet of the three-way catalytic converter 10, and the cleaning agent for the three-way catalytic converter is provided in the chemical tank 2; Both the valve 8 and the cleaning pump 3 are connected with the controller, and the opening and closing of the medicine tank valve 8 and the cleaning pu...

Embodiment 2

[0026] A three-way catalytic converter regeneration treatment method, comprising the following steps:

[0027] (1) Remove the three-way catalytic converter from the car and check whether the three-way catalytic converter is intact;

[0028] (2) The three-way catalytic converter is installed on the three-way catalytic converter regeneration treatment device, so that the gas outlet end and the air intake end of the three-way catalytic converter are respectively connected with the water inlet joint of the three-way catalytic converter and the water outlet joint of the three-way catalytic converter , and then turn on the cleaning pump to preliminarily clean the stains, dust and carbon deposits in the three-way catalytic converter with water;

[0029] (3) Open the chemical tank valve, make the three-way catalyst cleaning agent flush the three-way catalytic converter, clean the sulfur-phosphorus complex and carbon deposits therein, close the chemical tank valve, and continue to rins...

Abstract

The present invention provides a three-way catalyst regeneration treatment device. The device comprises a housing internally provided with a water tank, a medicament tank, a washing pump, a controller, a connecting line and a three-way catalyst water inlet connector, wherein the water tank and the medicament tank are individually connected with the washing pump, the washing pump is also connected with the three-way catalyst water inlet connector, the three-way catalyst water inlet connector is used for connection with an air outlet end of a three-way catalyst, the medicament tank is filled with a three-way catalyst washing agent, medicament tank valves are disposed on connection pipelines of the medicament tank and the washing pump, both the medicament tank valves and the washing pump are connected with the controller, and the controller controls opening and closing of the medicament tank valves and the washing pump. A three-way catalyst regeneration treatment method is also provided. According to the device and method, three-way catalyst internal carrier surface sewage can be washed by using a recycling pump under a compression condition, and aims of rapidly cleaning three-way catalyst internal carriers and recovering three-way catalyst precious metal activity are achieved, thereby realizing reuse of the three-way catalyst, lowering cost and reducing motor vehicle exhaust emission.

Description

[0001] technical field [0002] The invention relates to a three-way catalytic converter regeneration treatment device, and the invention also relates to a treatment method of the three-way catalytic converter regeneration treatment device. Background technique [0003] Due to the high content of sulfur, phosphorus and olefins in the gasoline used, the three-way purifier is generally scrapped after the car has driven 80,000 to 100,000 kilometers. The failure of the three-way catalytic converter carrier will convert toxic gases such as CO, CH and NO into non-toxic Insufficient gas will not only increase the exhaust volume of the vehicle and aggravate the pollution to the environment, resulting in substandard vehicle exhaust emissions, but also block the three-way catalytic converter and affect the power of the vehicle, resulting in insufficient power of the vehicle and increasing the fuel consumption of the vehicle. The average price of replacing the three-way catalytic conve...
