Problems solved by technology

At present, the capacity of my country's tail gas treatment devices is limited, and the harmful components in the tail gas cannot be completely removed. There are the following disadvantages: 1. The main harmful components in the tail gas cannot be removed, including CO, HC and NOx; 2. If the tail gas treatment device is blocked, it will cause exhaust gas. Air back pressure increases, reducing engine power

specific Embodiment approach 1

[0036] DETAILED DESCRIPTION One. The integrated process method of engine pretreatment, self-repairing materials and exhaust gas treatment includes the following steps:

[0037] Step 1. Prepare the mixed powder with the function of cleaning the surface deterioration layer, corruption spots and oil stains of the friction pair of the engine;

[0038] Mixed powder with the function of cleaning the surface deterioration layer, corruption and oil stains of the friction pair of the engine: According to the weight parts ratio, 45~55 parts of rare earth, 4~6 parts of iron powder, 4~6 parts of aluminum powder, 4~6 parts of zinc powder , 4-6 parts of silicon powder, 6-7 parts of magnesium powder, 4-6 parts of sodium powder, 4-6 parts of calcium powder and 3-4 parts of lithium stearate are placed in a high-speed homogenizer for 30-40 minutes;

[0039] Step 2: preparing a metal wear self-repairing material composition;

[0040] The metal wear self-repairing material composition is composed of 4-11...

specific Embodiment approach 2

[0078] Specific embodiment two, the rare earth, iron powder, aluminum powder, zinc powder, silicon powder, magnesium powder, sodium powder and calcium in step one described in the integrated process method of engine pretreatment, self-repairing material and exhaust gas treatment of this embodiment The particle size of the powder is less than 2 microns. The mixed powder of this embodiment can determine the thickness of the metamorphic layer and the corrupted spot to be cleaned according to the gap between the metal friction pairs.

specific Embodiment approach 3

[0079] Specific embodiment three, in the step two of the integrated process method of engine pretreatment, self-healing material and exhaust gas treatment of this embodiment, the metal wear self-healing material composition is composed of 4-11 parts by weight of nickel chloride powder, 4 to 11 parts of aluminum powder, 19 to 31 parts of nickel powder, 14 to 21 parts of ferric oxide powder, 4 to 11 parts of silica powder, 2 to 5 parts of powder suspension, 0.5 to 1 part of surface modifier Put 12 to 49 parts of mineral lubricant into a high-speed homogenizer and homogenize for 30 to 40 minutes.

Abstract

The invention discloses an engine pretreatment, self-repairing material and tail gas governing integrated process method and belongs to the technical field of engine tail gas governing. The inventionaims at solving the problems that an existing engine tail gas governing effect is not thorough, and the emission pollutants of an engine harm the living environment. The engine pretreatment, self-repairing material and tail gas governing integrated process method includes the following steps that firstly, mixed powder with the function of cleaning an engine friction pair surface metamorphic layer,rotted points and oil stains is prepared; secondly, a metal abrasion self-repairing material composition is prepared; thirdly, engine pretreatment is performed; fourthly, engine self-repairing treatment is performed; and fifthly, a tail gas after-treatment device is additionally arranged. According to the engine pretreatment, self-repairing material and tail gas governing integrated process method, by means of integration and advantage complementation of the three technologies of engine pretreatment and self-repairing and additional arranging of the tail gas treatment device, the technical defects that a current domestic engine is purely provided with a tail gas treatment device, the engine performance is lowered, the oil consumption rises, and a particulate trap can be easily blocked areovercome, and an effective path is provided for scientific prevention and treatment of tail gas of high-emission motor vehicles in future.

Description

Technical field [0001] The invention relates to a tail gas treatment method, belonging to the technical field of engine tail gas treatment. Background technique [0002] The main pollutants in the exhaust of engines (including gasoline and diesel) are carbon monoxide (CO), hydrocarbons (HC), nitrogen oxides (NOx), sulfides and particulates (from carbon particles, lead oxides and other heavy metal oxides) And soot). The purification method is that the exhaust gas will be generated by the chemical reaction of oxidation and reduction of the catalyst. 2 O, CO 2 And N 2 Wait to be discharged into the atmosphere. [0003] According to scientific research, NOx, sulfide and particulate emissions are the main causes of smog in my country. In fact, for diesel vehicles, the largest pollutant is nitrogen oxides (NOx). In terms of quality, nitrogen oxides (NOx) emission is 50-200 times that of PM emission, which is the main factor that is toxic to organisms. At present, my country’s exhaust g...
