Embodiment Construction

[0021] The present invention will be described in detail below in conjunction with specific embodiments and accompanying drawings.

[0022] A kind of particle separator of water spraying type adsorption diesel engine exhaust in the spiral tube of the present embodiment, such as Figure 1 to Figure 3 As shown, it includes a cylinder 1, two end plates 2, a spiral tube 5 and a spiral elbow 6. The cylinder 1 and the end plates 2 together form an inner cavity, and the two end plates 2 are respectively provided with a connecting cavity. Air inlet 3 and air outlet 4. The spiral tube 5 includes a tube body 51 and helical fins 52. The two ends of the tube body 51 are respectively fixed on the corresponding end plates 2. The fins 52 are fixed on the outside of the tube body 51, and the outer edges of the fins 52 just touch The inner wall of the cylinder body 1 is closed, so that the cylinder body 1 and the spiral tube 5 together form a helical adsorption channel. Elbow 6 is provided w...

Abstract

The present invention discloses a water-spraying particle separator in serpentine pipe for adsorbing diesel exhaust. The using method is as follows: the liquid is introduced from an inlet of a serpentine pipe, and the liquid is ejected from respective water spray nozzles during the flow, thereby forming a water mist in the serpentine pipe. The exhaust from a diesel engine enters the inner cavity from an air inlet and moves along the serpentine pipe. Particles in the exhaust are wetted by the water mist, and settled during the movement, so that the water mist and the particles both sink to a collecting tank arranged in the bottom; the purified exhaust is discharged from an air outlet to the atmosphere. The serpentine pipe bends for a long time, and is capable of extending the moving path ofthe exhaust in a certain space, thereby improving the adsorption effect of exhaust particles; furthermore, the water mist slows down the moving speed of the exhaust to a certain extent, so that the particles are fully adsorbed. The particle separator disclosed by the present invention has the beneficial effects of simple structure at a low cost.

Description

technical field [0001] The invention relates to the technical field of diesel engine tail gas purification, in particular to a particle separator for absorbing diesel engine tail gas by spraying water in a spiral tube. Background technique [0002] Diesel engines are widely recognized for their strong power, good economic performance and high thermal efficiency, and are widely used in the field of vehicles. The pollution caused by the additional exhaust emissions to the environment is also becoming more and more serious, so it is urgent to strengthen the control and governance of automobile exhaust emissions. The pollutants emitted by automobile exhaust are carbon monoxide, hydrocarbons, nitrogen oxides, and some other solid particles that have adverse effects on the human body. The composition of solid particles is complex and has strong adsorption capacity. It can absorb various metal dusts, strong carcinogens, benzopyrene, and pathogenic microorganisms. Solid suspended p...
