Description
Technical field
This utility model is related to automobile technical field, more particularly to a kind of gas and oil separating plant and including the Oil-gas Separation
The EVAP Evaporative System and automobile of device.
Background technology
Fuel oil (such as gasoline) is the fuel of highly volatile, and the fuel oil in automotive oil tank constantly can be evaporated so as to cause in fuel tank
Pressure increase, fuel tank internally pressure exceed certain value when will produce danger.For the pressure in trim tank, fuel tank cap
On be often provided with pressure limiting valve, when tank internal pressure exceedes certain value, pressure limiting valve is opened, and steam in fuel tank is discharged.With
Past, this part fuel vapor is often discharged directly into air, has not only wasted fuel but also extremely serious damage is caused to environment
Evil, so national governments require that automobile vendor takes measures one after another.
One after another using canister adsorbing the fuel vapor discharged from fuel tank, Fig. 1 is integrated in prior art for automobile vendor
The structural representation of the canister of gas and oil separating plant, refer to Fig. 1, and the canister 100 includes Oil-gas Separation portion 120 and vapor sorption
Portion 130, Oil-gas Separation portion 120 are located on vapor sorption portion 130, and the inside in Oil-gas Separation portion 120 and vapor sorption portion 130 is equal
Be formed as cavity (not shown), 120 internal cavities of Oil-gas Separation portion are with 130 internal cavities of vapor sorption portion by dividing plate (not shown)
Separate, on dividing plate, be provided with canister air inlet (not shown), 120 internal cavities of canister air inlet connection Oil-gas Separation portion and steam
130 internal cavities of adsorption section, 130 internal cavities of vapor sorption portion are arranged on canister 100 by adsorptivity very strong activated carbon filling
There are steam inlet pipe 140, steam escape pipe 150 and air breather 160, (figure is not by adsorption tube for 140 one end of steam inlet pipe
Show) connect with fuel tank, the other end and 120 connects with the internal cavities of Oil-gas Separation portion, 150 one end of steam escape pipe passes through desorption pipe
(not shown) is connected with electromotor, and the other end is connected through 120 internal cavities of Oil-gas Separation portion with 130 internal cavities of vapor sorption portion
