Automobile three-way catalytic converter automatic cycle cleaning machine

Abstract

The invention discloses an electric vehicle cycle cleaning machine for an automotive three-way catalyst. A burdening tank (2), a filter (3) and a circulating pump (4) are arranged in a case (1), a water inlet (5) is formed in the upper part of the case (1) and is connected with a tap water tube, a water outlet (6) is formed in the lower part of the case (1) and is connected with a water drain pipe on the burdening tank, tap water flows into the burdening tank (2), the filter (3) and the circulating pump (4) through pipelines, the burdening tank, the filter and the circulating pump are connected through pipelines which are provided with a plurality of electromagnetic valves (7) for controlling on and off of the pipelines, the top of the burdening tank is provided with a feeding door (8), an electric heater (9) is arranged at the lower part of the burdening tank, and the case is provided with two output ports (10) which are respectively connected with input and output connectors of the three-way catalyst. According to the automatic cycle cleaning machine disclosed by the invention, a heating closed circulation system is formed in the cleaning machine, and the purpose of rapidly recovering the catalysis property of the three-way catalyst can be achieved in assistance with an oscillating means, the exhaust back pressure of an engine is improved and the tail gas purification capability is recovered.

Description

technical field [0001] The invention relates to an automatic cleaning device, in particular to an automatic cycle cleaning machine for a three-way catalytic converter of an automobile. Background technique [0002] The three-way catalytic converter is the most important external purification device installed in the exhaust system of automobiles. It can convert harmful gases such as CO, HC and NOx discharged from automobile exhaust into harmless carbon dioxide, water and other harmful gases through oxidation and reduction. Nitrogen. HC and CO are toxic gases. Excessive inhalation can lead to death, while NOX can directly lead to photochemical smog. Most of the urban environmental pollution and atmospheric haze come from incompletely catalyzed vehicle exhaust. [0003] When the high-temperature automobile exhaust gas passes through the purification device, the catalyst in the three-way catalytic converter will enhance the activity of CO, HC and NOx, and promote a certain oxid...
