Embodiment Construction

[0013] Accompanying drawing shows the structure of the present invention, further describe the embodiment of its structure and working principle below again in conjunction with accompanying drawing.

[0014] Motor vehicles cannot run without exhaust pipes and mufflers. There are four main types of mufflers: absorption type, interference type, expansion type, and resonance type. Generally, better cars have three mufflers, common ones have two mufflers, and common ones have one muffler. For cars with three mufflers, the front muffler is metal with a simple structure and high temperature resistance. Corrosion resistance, long service life, the middle one is a combination of absorption and resonance, there are two multi-pipe holes and two partitions inside to form two resonance chambers, which are filled with sound-absorbing materials such as asbestos, and the rear muffler is absorption and expansion Various combinations of type and resonance type, the exhaust gas circulates in t...

Abstract

The invention relates to a device for purifying tail gas dust-haze of an automobile, which aims at eliminating tail gas dust-haze, improving the air quality, improving the environmental condition and ensuring human health. The device for purifying tail gas dust-haze comprises an exhaust tube and a silencer, and is characterized in that a barrier filter screen is arranged in the silencer; the silencer is partitioned into at least two units by the barrier filter screen; the silencer is made into a water tank type silencer; liquid is injected into the silencer; an exhaust tube inlet, an exhaust tube outlet and a liquid injection hole are formed in the top of the silencer; a liquid sewage draining hole is formed in the bottom of the silencer; and a high-edge indicator for monitoring the water level is arranged in the silencer. The device has the beneficial effects that the tail gas dust-haze of the automobile is purified; and if about 200,000,000 existing used automobile in China are refitted and new automobiles which are not delivered are arranged according to the design, automobile tail gas pollutants which are directly discharged into the atmospheric air can be reduced greatly, the environmental protection level is raised, and the environmental temperature is improved.

Description

technical field [0001] technical field [0002] The invention relates to the treatment of motor vehicle exhaust, in particular to the treatment of automobile exhaust ash, and further relates to the invention of a purification device for the treatment of diesel automobile exhaust ash. Background technique [0003] In the prior art, automobile tail gas haze emission pollutes the atmosphere and endangers human health, which has become a prominent problem in the world and has become an invisible killer. According to the information published in the 2011 "Annual Report on the Prevention and Control of Motor Vehicle Pollution in China", my country is the world's largest automobile production and sales country. During the Eleventh Five-Year Plan period, the number increased from 180 million to 190 million. Among them, 5.994 million tons of nitrogen oxides (NOx), 598,000 tons of particulate matter, 4.872 million tons of hydrocarbons (HC), and 40.8 million tons of carbon monoxide (CO...
