Description

Automobile tail gas purifier

Technical field

The utility model relates to a kind of purifier, belongs to a kind of automobile tail gas purifier.

Background technique

The increase year by year of auto output, the tail gas of motor vehicle emission have become the pollution sources that flow, and be very serious to the harm of nature.Compositions such as the CO in the waste gas sent off from automobiles, HC, NO leadization thing and sulphide are very harmful to human body.In order to eliminate this serious social effects of pollution, strict Abgasgesetz is formulated in the area, countries in the world in succession.Therefore, improvement or Control of Automobile exhaust emissions have become global protection environment key subjects anxious to be solved.So-called purifying vehicle exhaust is taked all effective measures exactly, eliminates or reduce the discharging of pollutant, makes CO, HC, the NO difference catalysis in the discharging waste gas or filter to generate nontoxic CO ₂, H ₂O, N ₂In general, realize that purifying vehicle exhaust has two kinds of methods: i.e. engine interior control and external engine purify.The machine inner control is utilized the working procedure of motor own to reduce automobile exactly and is entered pollutant, and it is that automobile enters one of main method of control.Countries in the world automobile production producer has taked a lot of measures respectively at Carburetor and context engine, as electronic fuel injection, lambda sensor control technique etc., all these measures all have certain effect to eliminating or reducing automotive emissions, but act on limited in addition have also can bring some adverse influences to the power character and the Economy of motor.

Summary of the invention

The purpose of this utility model provides a kind ofly not to be had negative effect, can eliminate the automobile tail gas purifier of the pollutant of motor vehicle emission again motor.

The purpose of this utility model is achieved in that body is a box structure, is hollow article between the upper box of body and the lower box; Establish several rows of resistance bend pipe in hollow article, the upper end-hole of its resistance bend pipe places in the upper box, and the lower end mouth of its resistance bend pipe places in the lower box; Side at upper box is established outlet pipe, establishes suction tude on the upper box of body, and the outlet of suction tude places in the lower box; The inductor probe is arranged in the lower box of body; Put into water pipe on the upper box of body, the outlet of intake pipe places in the lower box; Drain valve is established in the bottom of lower box.

The utility model not only has easy for installation, sturdy and durable, cheap characteristics, and can be with harmful matter CO, the HC of the pollution sources of emission from vehicles, the CO that NO:O changes nonhazardous into ₂, H ₂O and N ₂, reduce pollution sources to environment, also can reduce noise simultaneously.

Description of drawings

Fig. 1 is the utility model embodiment's a structural representation

Embodiment

With reference to Fig. 1, body 7 is a box structure, is hollow article between the upper box of body 7 and the lower box; Establish several rows of resistance bend pipe 5 in hollow article, the upper end-hole of its resistance bend pipe 5 places in the upper box, and the lower end mouth of its resistance bend pipe 5 places in the lower box, and it is for preventing that automobile liquid when moving from directly oozing out from outlet pipe that resistance bend pipe 5 is set.Side at upper box is established outlet pipe 1, and the outlet of outlet pipe 1 places outside the upper box, and the gas that filter purifies is discharged.The upper box of body 7 is established suction tude 3, and the outlet of suction tude 3 places in the lower box, and the import of suction tude 3 places that body 7 is outer to be propped up interface tube with engine exhaust and be connected.Dress inductor 4 on the indoor instrument panel of vehicle drive, inductor 4 is the assembly of electronics water temperature and water level sensor, the probe of inductor 4 through flexible pipe as for lower box in, the water level in the lower box, water temperature are reported to the police or are shown.The upper box of body 7 is established intake pipe 2, and the outlet of intake pipe 2 places in the lower box, and catalytic liquid is to place in the lower box by intake pipe 2; Drain valve 6 is established in the bottom of lower box, and drain valve 6 is for preventing ice up in winter or catalytic liquid muddiness, needing discharge to use.Body 7 is installed on the skeleton on every side of external engine exhaust branch pipe chassis.The material of body 7 will adopt mechanical strength height, good heat resistance, do not contain material that catalytic liquid is poisoned, with catalytic fluid interactional material does not take place.Catalytic liquid in the lower box is a water, also can be can adapt to the acute variation of the gas shock of frequent atmosphere and temperature and component, have a catalytic fluid of the activity of high temperature (more than 800 ℃) and low temperature (00 ℃) simultaneously.

Claims

1, a kind of automobile tail gas purifier, body (7) is a box structure, makes to be characterised in that: between the upper box of body (7) and the lower box is hollow article; Establish several rows of resistance bend pipe (5) in hollow article, the upper end-hole of its resistance bend pipe (5) places in the upper box, and the lower end mouth of its resistance bend pipe (5) places in the lower box; Establish outlet pipe (1) in a side of upper box, the upper box of body (7) is established suction tude (3), and the outlet of suction tude (3) places in the lower box; The probe that inductor (4) are arranged in the lower box of body (7); The upper box of body (7) is established intake pipe (2), and the outlet of intake pipe (2) places in the lower box; Drain valve (6) is established in the bottom of lower box.
