Described a kind of automobile exhaust gas purifying installation is characterized in that: be connected with atomization tank in offgas duct between silencing apparatus and atomization tank.
Described a kind of automobile exhaust gas purifying installation is characterized in that: the top of silencing apparatus is connected by the air-strainer of pipeline with the motor upstream.
The utility model relates to a kind of automobile exhaust gas purifying installation following advantage:
The one, the stroke of tail gas in absorption liquid is long, is 3 times of stroke in the documents.Tail gas is abundant with mixing of absorption liquid like this, and prolong time of contact relatively, and the harmful substance mass-energy in the tail gas is fully absorbed thorough tail gas treatment.
The 2nd, owing on the offgas duct between atomization spray cap and the silencing apparatus, be connected with atomization tank, alleviated the pressure surge of motor exhaust, make the silencing apparatus internal air pressure stable, make this device working stability.

Embodiment
A kind of automobile exhaust gas purifying installation, its structure comprise water storage box 2 and silencing apparatus 14 as shown in drawings, and silencing apparatus 14 is connected on the offgas duct 12.Like this, the waste gas that produces during engine operation must be handled and could discharge through purification plant.Silencing apparatus 14 is airtight relatively container, is loaded with absorption liquid 10 in the silencing apparatus 14, and the exit position of offgas duct 12 is lower than the position of absorption liquid 10 liquid levels.When waste gas enters silencing apparatus 14, at first to pass through absorption liquid 14, the harmful matter in the waste gas is mixed with absorption liquid 14.Silencing apparatus 14 is separated into 3 airtight relatively chambers by dividing plate 7, and the bottom of adjacent airtight chamber is connected by hole or gap 17.Design like this, the one, make the liquid level maintenance level of three chambers, the 2nd, convenient in the silencing apparatus 14 filling and discharge absorption liquid 10.Adjacent two chambers connect by connecting tube 11, and the entrance point that connecting tube 11 runs through dividing plate 7 is positioned at the top of the chamber that is in upstream position, and its position is higher than the position of absorption liquid 10 liquid levels.The outlet end of connecting tube 11 is positioned at the bottom of the chamber that is in downstream position, and its position is lower than the position of absorption liquid 10 liquid levels.12 upstream is connected with water storage box 2.
