Abstract

The utility model relates to a vehicle waste gas purifying device, in particular to a vehicle tail gas purifying device. The vehicle waste gas purifying device aims at solving the emission problem of harmful tail gas of vehicles. The scheme of the vehicle waste gas purifying device is as follows: tail gas is filtered by a purifying box, so as to lead harmful substances in the tail gas to be dissolved in water or filtered by a filtering net, thereby reducing the harmful substances in the emitted tail gas; by utilizing heat of the tail gas, gases are generated by hydrogen peroxide in a waste gas pipe interlayer and enter an engine combustion chamber to be completely combined with fuel so as to lead the combustion to be more complete; the harmful substances in the emitted waste gas are reduced; anion air is conveyed into a fuel pipe, so as to increase the oxygen content in the fuel, thereby improving the combustion rate of the fuel. The vehicle waste gas purifying device greatly reduces the content of carbon monoxide, nitrogen dioxide and the like in the tail gas.

Description

A kind of device for purifying waste gas from vehicle

Technical field

The utility model relates to a kind of gas cleaning plant, is specifically related to a kind of vehicle tai-gas clean-up device.

Background technique

In various environomental pollution sources, the internal-combustion engine institute exhaust gas discharged of dynamic power machines such as vehicle, locomotive has accounted for major part; Therefore, how to reduce the generation that each dynamic power machine pollutes waste gas, be a current big problem.And be to reach to suppress the effect that waste gas produces, at first should understand the constituent of the waste gas of dynamic power machine internal-combustion engine earlier.

For example: the gasoline as internal-combustion engine major impetus source is a kind of hydrocarbon, nearly all carbon and hydrogen atom in petrol molecule, can produce carbon dioxide and water after these carbon and hydrogen atom and the air mixing burning, but be discharged because mixed with little amount gas is imperfect combustion, so can produce HC (hydrocarbon) and CO (carbon monoxide).Moreover, enter in the air in the internal-combustion engine, contain 80% nitrogen (N ₂), through the high temperature of firing chamber, originally very stable nitrogen can close with airborne oxidation, produces nitrous oxide and nitrogen dioxide, not only can cause the pollution of environment and can damage human body.Above-mentioned hydrocarbon and nitrous oxide all are because incomplete combustion produces, and eliminate them and just must make mixed gas perfect combustion.

And be to make mixed gas reach the effect of perfect combustion, the dealer has developed multiple technologies at present, comprise: waste gas is reclaimed burn, utilize magnetic force that the macromolecular structure of gasoline is decomposed into modes such as little molecule once more, provide different promotions to burn, and contributed for reducing atmospheric pollution with fuel-efficient approach.Aforesaid way can not improve the dissolved oxygen amount in the gasoline, to reach the effect that increases combustion and strengthen shaft horsepower.Even and if mixed gas is close to perfect combustion, also can not solves the positive ion Electrostatic Absorption phenomenon that the motion of internal-combustion engine inner carrier is produced, and increase the problem of piston operation resistance.The waste gas that can not avoid discharging is suspended in the air.Therefore, strengthening horsepower, fuel-efficient efficient and reducing the space that still makes progress on the air-polluting effect.

Also very high with the harmful matter in diesel oil work done compression type combustion engine (internal-combustion engine), the spark-ignition engine tail gas at present, tail gas energy is not fully utilized yet, and the tail gas designation number that the bavin petrol engine of existing operation is discharged is uneven, the motor acting fuel oil quality difference of using differs, poisonous in a large number, the harmful matter that produce during work done are discharged in the air, environmental pollution is very big, has endangered health.Currently used " three-element catalytic " technology can only reach environmental requirement, and energy is not fully utilized.

Temperature was very high after Vehicular exhaust was come out by outlet pipe at present, and this heat does not generally all have to utilize, and it raises through easily making fluid temperature behind liquid, unfavorable waste gas dissolving.

Disclose a kind of waste gas filter that utilizes two purifying boxs as ZL200720092683.3, strengthened filtering effect, but adopted two purifying boxs to increase volume, installed inconveniently, had in the limited space of vehicle utilization ratio not high.

ZL200720034999.7 discloses and a kind ofly a blowdown pipe is installed on engine exhaust pipe has been increased oxygen content in the outlet pipe, improve firing effect at last, the gas but it just covers, the oxygen content of the inside still very little, and some units that do not have other usually in and the nitrogen-atoms in the fuel, utilize mode single.

The model utility content

In order to address the above problem, this programme provides a kind of waste gas cleaning plant, and this programme first purpose is that exhaust gas discharged is purified, and second purpose is fuel saving and stable emissions waste gas, and the 3rd purpose is to utilize waste-gas heat.
