no. 1 example

[0024] see Figure 1-Figure 4 , an internal combustion engine exhaust gas purification muffler, including a purification muffler main body 1 and its air inlet 2 and air outlet 3, the purification muffler main body 1 includes two cavities, an air intake chamber and a purification chamber formed by partitions 4, wherein the purification chamber A combined structure of three gas baffles 5 and perforated plates 6 is provided inside to form a three-stage stepped purification channel; the lower part of the purification muffler main body 1 is provided with a waste gas treatment device, and the outside is connected to a water volume control device. The air intake chamber is separated by several partitions 4 to form a stepped cavity and a purification chamber with a one-way purification channel. The air intake chamber plays the role of buffering the airflow pulse and storing water when cooling the return water. The gas baffle 5 and the perforated plate 6 in the purification chamber ar...

[0029] see Figure 5 The difference between this embodiment and the first embodiment is that the air inlet chamber is separated from the purification chamber by several partitions 4 to form a slope-shaped chamber. Other unmentioned parts are the same as the first embodiment.

[0030] Working principle of the present invention: exhaust gas enters the air intake chamber through the air inlet 2 on the main body of the muffler 1, the air flow is buffered, and then enters the purification chamber filled with filtrate, wherein a small amount of water-soluble oxidant ( Such as: 1g / L NaClO), the exhaust gas is mixed with the filtrate for many times through the multi-stage porous plate, and the exhaust gas is purified. And an electrode reaction device is installed at the lower part of the purification chamber. Take the addition of NaClO as an example: NaClO decomposes in the solution to generate NaCl and active oxygen, and the active oxygen oxidizes water-insoluble NO into NO that can...

Abstract

An exhaust purification muffler for internal combustion engine comprises a purification muffler main body and a gas inlet and a gas outlet of the main body, wherein the purification muffler main body includes a gas inlet cavity and a purification cavity divided by partition plates, in the purification cavity is arranged a combination structure of plural gas stop plates and porous plates to form a purification passage of two or more steps, the lower part of the purification muffler main body is provided with an exhaust treatment device, the outer side of the purification muffler main body communicates with a water quantity control device, and the gas inlet cavity is isolated from the purification cavity by plural partition plates to form an oblique plane-like or step-like cavity. The invention realizes purification and muffling effects by forming the purification passage of two or more steps in the purification cavity, controlling the height of the liquid level in the cavity, employing an electrode reaction device to increase and sustain the oxidizing property of filtered liquid and increasing nitrogen oxide absorption by the filtered liquid; has advantages of low cost, long service life, low running cost and good purification effects; and is suitable for treatment of automobile exhaust.

Description

technical field [0001] The invention relates to an internal combustion engine exhaust gas purification muffler, which is mainly used for exhaust gas purification and muffler of internal combustion engine vehicles. Background technique [0002] At present, with the continuous improvement of living standards, the number of internal combustion engine vehicles is increasing, and the pollution of the exhaust gas of internal combustion engine vehicles to the atmosphere is becoming more and more serious. To the first place, buses with black tails are simply killers of urban air. Many cities have fewer and fewer blue skies, and the existing purification devices are either high in cost or ineffective (especially for PM2 .5 or less dust absorption), there is an urgent need for a low price, long service life, low operating cost, and a good internal combustion engine motor vehicle exhaust gas purification device with good purification effect, so that popular use. Such as Chinese Patent...
