Embodiment Construction

[0039] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0040] First, the dielectric barrier discharge is introduced.

[0041] The principle of dielectric barrier discharge is to insert at least one layer of insulating medium between the two electrodes of the discharge.

[0042] According to the location of the insulating medium, dielectric barrier discharge can be divided into the following two cate...

Abstract

The invention discloses a device for processing engine tail gas and an engine. The device is boxlike and comprises a first surface, a middle isolation layer, a second surface, a spiral insulating core, an inlet and an outlet; the second surface and the first surface are respectively of a positive electrode and a negative electrode; the middle isolation layer is an insulation medium, the middle isolation layer is arranged between the first surface and the second surface, and a first predetermined distance and a second predetermined distance are respectively separated between the first surface and the middle isolation layer and between the middle isolation layer and the second surface in sequence; and a spiral tubular cavity for volume dielectric barrier discharge exists between the middle isolation layer and the second surface. When the device works, the engine tail gas passes by the inlet at first, performs the volume dielectric barrier discharge in a spiral channel, and then flows outfrom the outlet. The device is additionally provided with a discharge path, and the defouling effect is improved.

Description

technical field [0001] The invention relates to the technical field of engine exhaust gas treatment, in particular to a device and an engine for treating engine exhaust gas. Background technique [0002] At present, people's requirements for living environment are getting higher and higher, so people pay more and more attention to air quality. In cities, engine exhaust is one of the main causes of air pollution. Engine exhaust pollution is the environmental pollution caused by the exhaust gas emitted by the engine. The main pollutants are nitrogen oxides and carbon monoxide, which can cause photochemical smog. [0003] Therefore, engine manufacturers need to gradually increase the processing capacity of engine exhaust. [0004] At present, the treatment of engine exhaust is mainly through catalytic reaction, that is, the use of catalysts to convert nitrogen oxides into non-toxic substances such as carbon dioxide, ammonia and water, and then discharge them into the air. ...
