On March 1, in implements《Environmental protection product technology requires vapour there be not vehicle fuel evaporation pollutant control system（Device）》, so far for
Only most domestic vehicle has reached the requirement of the discharge of state five.Current canister working condition：1, oil vapour discharge process：Fuel tank
After evaporating steam by canister absorption oil vapour, clean gas is discharged into air；2, canister purge process：Using setting out
The negative pressure driving source of motivation gas handling system, air enter engine combustion by the atmospheric air port air inlet of canister by carbon dust, desorption pipe
It burns.With the continuous improvement to emission request, the requirement to canister is also higher and higher, will implement six row of state in July, 2019
The requirement of regulation is put, just more stringent requirements are proposed to the adsorption capacity of canister for this, it is therefore necessary to carry out continuing to change to canister
Into, further to meet the requirement to its adsorption capacity, such as a kind of existing canister, as shown in Figure 1, 2, including internal setting
It is useful for filling active powdered carbon（It is not shown in figure）Filled cavity 10 tank body 1, be provided on the tank body 1 adsorption orifice 11,
Mouth 12 and atmosphere entry 13 is desorbed, a carbon-point component 2 is provided in the tank body 1, carbon-point component 2 includes being set to inside
Carbon-point and be set to the mounting cylinder in outside, be formed with air flue inside canister 1, the air flue passes through adsorption orifice 11 successively（Or
Mouth 12 is desorbed）, filled cavity 10, carbon-point and atmosphere entry 13.This canister for being internally provided with carbon-point, the installation of carbon-point component
Structural soundness is poor, and carbon-point component usually occurs shifting situation in use.
Utility model content
Therefore, filled cavity in tank body can be separated into two parts the purpose of this utility model is to provide a kind of, from
And convenient for the activated carbon powder of two kinds of different models of filling, to improve the adsorption capacity of canister, and carbon-point component can also be improved
Mounting structure stability carbon dust separating device.
To achieve the goals above, a kind of carbon dust separating device of the utility model, the carbon dust separating device is for installing
In the filled cavity filled with carbon dust inside canister, including a partition board, a pilot hole, the assembly are provided on the partition board
Hole passes through and fixes for carbon-point component, and several ventilating grooves, the difference of both sides up and down of the partition board are provided on the partition board
It is provided with filter screen.
The marginal position of the partition board is provided with several side plates perpendicular to the partition board.
Using above-mentioned technical proposal, the carbon dust separating device of the utility model can separate the filled cavity inside canister
The carbon dust of filling different model is respectively used to as two parts, to further increase the adsorption capacity of canister；Carbon dust separates simultaneously
Device also has the function of fixed carbon rod assembly, and the stability of carbon-point component is made to be improved.
Description of the drawings
