Problems solved by technology

[0004] In order to overcome the disadvantages of high cost, ineffective effect and poor practicability of existing treatment devices, based on the principle of water washing: the exhaust gas from automobiles contains many harmful substances in the form of fine particles, which can absorb water and swell after washing and showering Large, settle by gravity, and then filter and absorb, so as to achieve the purpose of removal

Embodiment Construction

[0017] When the automobile was started, the miniature booster pump (3) started to work, and the water in the water tank (5) was passed into the water atomization pressure nozzle (15) by the water inlet pipe (4) and started to spray water, and the tail gas discharged from the automobile was discharged from the exhaust pipe (1 ) directly into the spray purification box (2), the atomized water sprayed by the nozzle is mixed with CO, CO2, HC, NOX, lead compounds, sulfur oxide compounds, incompletely burned carbon particles, etc. in the exhaust gas, collide with each other and adsorb, Fine particles swell due to absorbing water, and the presence of water mist will also make the particles adsorb each other and gather together to form larger particles. Then enter the gas-liquid separation settling tank (14), due to the sedimentation of the expanded particles due to gravity, wherein the larger particles are filtered in the gas-liquid separation settling tank through the sieve (14-3), a...

Abstract

The invention discloses a multiple-effect automobile exhaust purification device, comprising a water tank, a mist spray purification tube, a gas-liquid separation settling tank, a gas treatment tube and a liquid treatment tube. The device is based on a washing and showering exhaust purifying principle, through carrying out water atomization and gas and liquid separation on exhaust, further purification treatment is carried out, a three-way catalyst is adopted for converting harmful gas not subjected to water atomization in gas into pollution-free gas to be discharged to the atmosphere, active carbon adsorption is used for removing harmful substances in liquid obtained by settling through water atomization, and the purified water is recycled through the water tank. The multiple-effect automobile exhaust purification device can be used for not only greatly reducing emission of particles, but also carrying out hazard-free treatment on the harmful gas and realizing recycle of water, so that the goals of energy conservation and emission reduction are really achieved.

Description

1. Technical field [0001] The invention relates to a purification device, in particular to a multi-effect automobile tail gas purification device. 2. Technical background [0002] Since the birth of the first automobile in 1886, it has brought great convenience to people's life and work, and has developed into one of the pillars of modern material civilization. However, with the sharp increase in the number of cars, not only has there been frequent traffic jams, but it has also caused serious pollution to the atmosphere. At present, automobile exhaust has become the main source of air pollution in large and medium-sized cities, and it is also one of the main sources of PM2.5 in large and medium-sized cities that has recently received high attention from the society. The smog weather that lasted for many days in Beijing in early 2013 is a strong proof. [0003] Vehicle exhaust contains a large number of harmful substances, including carbon monoxide (CO), nitrogen oxides (NO ...
