Description
Technical Field
The invention belongs to the technical field of environmental protection, and particularly relates to an environment-friendly tail gas discharge pipe.
Background
With the popularization of automobiles, a large amount of exhaust gas emitted from automobiles is a significant factor of air pollution. Gasoline is mainly composed of carbon and hydrogen, and generates substances such as carbon dioxide, water vapor and excessive oxygen when the gasoline is normally combusted. However, because the fuel contains other impurities and additives, and the fuel is often not completely combusted, some harmful substances, including solid suspended particles, carbon monoxide, nitrogen oxides, hydrocarbons and lead, are often emitted.
The solid suspended particles enter the lung of a human body along with respiration and are retained at different parts of a respiratory tract in collision, diffusion, deposition and other modes to cause respiratory diseases. Carbon monoxide enters blood circulation through respiratory tract, and after affinity with hemoglobin, carboxyhemoglobin is generated, so that the function of oxygen delivery of blood to various tissues is weakened, the central nervous system is damaged, functional disorders such as feeling, reaction, understanding, memory and the like of people are caused, and serious people damage the blood circulation system, thus causing life risks. Nitrogen oxides are gases harmful to the human body, especially to the respiratory system. Lead is a toxic heavy metal element, most of automobile oil is doped with an explosion-proof agent tetraethyl lead or methyl lead, and lead and compounds thereof generated after combustion are toxic substances. More than 60% of lead in urban atmosphere comes from the combustion of automobile leaded gasoline. Lead content in the human body exceeds the standard, which can cause cardiovascular system diseases and influence the functions of important organs such as liver, kidney and the like and nervous systems. Lead dust, due to its high specific gravity, typically accumulates in the air at a height of around 1 meter and is therefore the most threatening to children.

Detailed Description
The present invention will be described in further detail with reference to specific examples, but the embodiments of the present invention are not limited thereto.
Referring to fig. 1, fig. 1 is a schematic structural diagram of an environment-friendly exhaust gas discharge pipe 8 according to the present invention. The environment-friendly tail gas discharge pipe 8 comprises a tail gas discharge pipe 8 and a tail gas filtering device, wherein the tail gas filtering device is detachably connected with the tail gas discharge pipe 8.
As a detachable mode, the tail gas filtering device is sleeved on the tail gas discharge pipe 8, and the sleeved part is fixed through a hose clamp.
As another detachable mode, the tail gas filtering device is sleeved on the tail gas discharge pipe 8, at least three screw holes are uniformly formed in the sleeved position of the tail gas filtering device, and the tail gas filtering device is fixed on the tail gas discharge pipe 8 through screws.
The detachable tail gas pipe filter device has the advantages that the modification cost of the tail gas pipe can be reduced, the installation is convenient, a user does not need to replace the tail gas pipe again, and only the tail gas filter device is installed on the existing tail gas pipe.
The exhaust gas filtering device comprises: the shell body 1, one port of the shell body 1 is an opening, and the other port is a hole-shaped or net-shaped structure. A first filter layer 2, a second filter layer 3 and a third filter layer 4 are sequentially arranged from the one port to the other port in the shell 1; the first filter layer 2, the second filter layer 3 and the third filter layer 4 are detachably mounted in the housing 1. As an embodiment, the detachable mode can be that two contact surfaces are fixed by the collision bead 5, or can be fixed by other detachable modes; adopt the fixed mode of detachable, the purpose is convenient for in time change the filtering layer material. In order to facilitate replacement, a pull ring 6 can be arranged on each filter layer and is directly pulled out during replacement.
Specifically, the first filter layer 2 is a copper oxide layer, and because copper oxide has strong oxidizability, carbon monoxide in tail gas can be instantly oxidized, and carbon monoxide is oxidized into carbon dioxide which does not pollute the environment. The structure of the copper oxide layer is a circular metal net, the circumference of the circular metal net is fixedly connected with a metal ring, and the outer wall of the metal ring is fixed in the shell 1 through a collision bead 5.
