Diesel Particulate Filter Cleaning system

Cleaning system to protect the Diesel Particulate Filters and the Vehicle’s engine by cleaning

the accumulated soot effectively

Features

1. Cleaning performance

-Cleaning efficiency

Average pressure reduction before and after cleaning: 90% +/- 5% (ex. Before cleaning, 500mbar

after cleaning, 50mbar, 90% reduction)

-ASH discharged

Mandatory discharging of ashes after cleaning (need to discharge ashes (iron and heavy metal)

clogged in the filter hole)

-Compressor performance

Max supplied pressure : 9 bar Max supplied fluid:200liter/min, screw type

-Static pressure tank

More than 180 liters(constant pressure/fluid maintained, buffering the surge pressure within the

device)

-Oil water separator and pressure regulator Nozzle: 1st oil water separator and pressure

controller(minimized pressure reduction)

-Blaster air

1st, 2nd, 3rd oil water separator and pressure controller(improves the cleaning efficiency)

-Dust collector air

1st and 2nd oil water separator and pressure controller(diameter 10 to 15A)

-Burner

PM to severely clogged filters heating need by Force convection or radiant heat

2. Environment performance

1st PM collector

Collects relatively large PM and iron/heavy metal. (cyclone type)

2nd PM collector

Collects relatively small particles( PMs)

(Germany design technology applied/fine particle collection/auto continuous)

*Amount of PM passing through the 1st and 2nd PM collectors: 0%

(measurement of reflection)

Rinsing air supply

Supplies the rinsing air for automatic pulsing of the secondary PM collector(maintains consistent collection ability/can perform continuous works)

Dust collection fan

Output of 2ps or more/turbo fan type

3. IT performance

Vehicle information

Stores the sensor signals during cleaning.(check the process) – cleaner’s local PCVehicle DPF cleaning history stored. Can analyze the status of cleaning at each site(internet). Can perform central monitoring of the cleaners.(main server)

Customer information

Can check the customer information by using the vehicle number(cleaner’s local PC) – wireless internet

Work information

Stores the sensor signals during cleaning.(check the process) , Stores the start/end time. Periodically uploads the work information to the main server

(determines whether to operate the cleaner.). Encrypted cleaning data in a PC – can’t operate it. Prevents modification of the customer data/hacking – can’t operate the cleaner.

Central management system

Manages the uploaded work data at the main server(statistics)

- statistics on the amount/date/type of cleaning. Restricted period of using the cleaner- can’t clean. Automatically downloads the cleaner’s control program and data that are modified

(main server to local PC).

4.Convenience performance

Automated cleaner

Automatic cleaning works.

Compatibility of the cleaner

Old model of passive type filter: H3/H2 New model of passive type filter: H3/H2 Active type filter: ACT.-B Developed a zig suitable for a filter’s diameter and height(can clean all types of filters)
