Abstract

The invention relates to the field of automotive exhaust emission, in particular to a simple device for reducing automotive exhaust dust and especially reducing automotive exhaust dust emission. Dust contained in exhaust are caused by impurities of oil products and abrasion of parts, and in order to reduce emission of automotive exhaust dust, the device for reducing the automotive exhaust dust is designed. The technical scheme includes that a water container is connected in and positioned at the tail end of an exhaust pipeline, exhaust enters an exhaust pipeline through an exhaust inlet and enters the water container through an exhaust nozzle, an exhaust pipeline of the exhaust nozzle is bent downwards to enable most of dust and water-soluble substances to be injected into water in the water container, and purified gases are discharged into the air through an exhaust discharging port of the exhaust pipeline. The simple device for reducing the automotive exhaust dust has the advantages that part of moisture in hot exhaust is condensated and retained, water body and moist air in the water container is beneficial to dust to retain the water body, and the device is low in cost and evident in dust retaining effect.

Description

A kind of device of easy minimizing vehicle exhaust dust

Technical field

The present invention relates to the motor vehicle exhaust emission field, particularly reduce the discharging of vehicle exhaust dust, reduce the concentration of PM2.5.

Background technique

The impurity of oil product and the wearing and tearing of device, the burning of fuel oil causes containing in tail gas dust, and tail gas directly discharges atmosphere, causes the rising of airborne PM2.5 concentration, affects resident's respiratory health.

From the treatment device of the vehicle exhaust announced suitable complexity all, with high costs, and be all disposable parts, safeguard and control all difficults.

Summary of the invention

For reducing the discharging of vehicle exhaust dust, the present invention designs a kind of device of easy minimizing vehicle exhaust dust.

The present invention realizes that the technological scheme that goal of the invention adopts is: a kind of device that reduces the vehicle exhaust dust, formed by water container and exhaust pipe, and it is characterized in that: a water container is connected in the tail gas pipeline, and water container is in the end of tail gas pipeline; Water container has water filling hole, tail gas spout, drain opening and relief opening; Tail gas enters exhaust pipe from the tail gas import, enter water container from the tail gas spout, the exhaust pipe of tail gas spout is bent downwardly, and in the water with most of dust and water-soluble material injected water container, the tail gas of purified gas by exhaust pipe effluxes and mouthful is discharged in atmosphere; Every the 1000-2000 kilometrage, open the waste water that drain opening is discharged water container, be poured on sewage conduct, then seal drain opening, inject moisture from water filling hole.

The tail gas jet opening distance water surface is at 1-2cm; Exhaust pipe effluxes a mouthful end and tilts from the tail gas entrance point to tail gas, tail gas entrance point ratio exhaust gas effluxes mouthful high 5-8cm of end.

The invention has the beneficial effects as follows: the part moisture that contains in hot exhaust gas, condensation is stayed in water container; The foam that the tail gas spout blows afloat, keep the water container environment moistening, the exhaust pipe of tail gas spout is bent downwardly, and the dust or the water vapour that are conducive in water conservancy diversion tail gas enter in water body, impel the dust of the overwhelming majority to be trapped in water container, make that to be discharged into airborne tail gas cleaner; Installation cost is cheap, and delay dust effect is remarkable.
