An engine self-inspection regeneration exhaust gas treatment system

Abstract

The invention discloses a self-inspection regeneration processing system for tail gas of an engine. The self-inspection regeneration processing system comprises a tail gas processing mechanism, a cyclic regenerating mechanism, a storing mechanism and a control module, wherein the tail gas processing mechanism comprises a decomposing pond, a filtering cabin and an air duct; the cyclic regenerating mechanism comprises a first suction pump, a liquid drainage pipe and a liquid drainage valve; the storing mechanism comprises a storage chamber, a first three-way valve, a first input pipe and a second input pipe; and the control module comprises a first pressure sensor, a second pressure sensor and a controller. According to the self-inspection regeneration processing system for the tail gas of the engine, provided by the invention, gas in the filtering cabin is filtered through a filter to enter the decomposing pond from the air duct, the filter can trap particulate matters in the gas, and decomposition liquid can decompose or dissolve harmful ingredients in the gas. The first three-way valve can be used for controlling the tail gas of the engine to enter the storing chamber to be stored, so that the condition that when the filtering cabin is actively regenerated, the tail gas of the engine is directly exhausted to atmosphere to cause damage can be avoided.

Description

technical field [0001] The invention relates to the technical field of engine exhaust gas treatment, in particular to an engine self-inspection regeneration exhaust gas treatment system. Background technique [0002] At present, harmful gases such as black smoke particles (PM) and nitrogen oxides (Nox) are produced in the exhaust emissions of engines of various specifications. With the gradual popularization of motorized equipment, the emission of harmful gases worldwide is increasing. , if these toxic gases are discharged into the atmosphere without treatment, it will lead to automatic mechanical devices installed in the exhaust pipe of the engine. [0003] Exhaust gas purification equipment in the prior art generally has the following defects: 1. The purification equipment has high requirements on the sulfur content of the oil; 2. The catalyst is easily poisoned and the purification function will quickly fail; 4. Directly burn and regenerate the filter body, which is easy...

[0002] At present, harmful gases such as black smoke particles (PM) and nitrogen oxides (Nox) are produced in the exhaust emissions of engines of various specifications. With the gradual popularization of motorized equipment, the emission of harmful gases worldwide is increasing. , if these toxic gases are discharged into the atmosphere without treatment, it will lead to automatic mechanical devices installed in the engine exhaust pipe

[0003] Exhaust gas purification equipment in the prior art generally has the following defects: 1. The purification equipment has high requirements on the sulfur content of the oil; 2. The catalyst is easily poisoned and the purification function will quickly fail; Excessive electricity; 4. Directly burn and regenerate the filter body, which is easy to damage the filter body; 5. The exhaust back pressure increases significantly, causing an increase in engine fuel consumption; 6. The manufacturing cost of the product is high, so the sales price is high and cannot meet market requirements
