Description

TECHNICAL FIELD

[0001] The utility model relates to diesel particulate filter technical field, concretely relates to a carbon ash collecting device of DPF pneumatic purging cleaning equipment. BACKGROUND

[0002] With the development of global e-commerce, logistics transportation as the bridge connecting producers and consumers, its development is increasingly rapid, and highway transportation and sea transportation as its main transportation mode, the development is more rapid, and the truck and ship using diesel as fuel are the main force of transportation. Diesel particulate filter (DPF) is a device installed in the exhaust system of diesel engine, which is used to capture and reduce the particulate emission in the exhaust of engine, and needs to be cleaned and regenerated regularly to adapt to the increasingly stringent environmental regulations. And pneumatic purging cleaning is one of the main methods of cleaning and regeneration.

[0003] The pneumatic purging cleaning of DPF is to place DPF in a relatively closed purging cavity space, use high-pressure air to blow out the carbon ash particles in each DPF micropore along the micropore channel in reverse, so as to achieve the cleaning and regeneration of DPF. The carbon ash particles blown out in this space will pollute the atmosphere if directly discharged into the atmosphere, and will cause respiratory diseases if inhaled by human body, so the device must be used to collect and concentrate the treatment.

[0004] Example one, use the dust collector to suck the carbon ash diffused in the purging space into the dust collector, this structure is simple, the cost is also not high, but the effect is very unsatisfactory, the negative pressure provided by the dust collector itself is not high, the pipeline is small, which leads to that the carbon ash in the space cannot be timely extracted and also cannot be extracted completely, and there will be more carbon ash diffused in the purging space after opening the equipment door after purging.

[0005] Example two, use the negative pressure fan to provide negative pressure, filter through the filter, the carbon ash adheres to the outer surface of the filter element, the relatively clean air is discharged to the fan cavity through the fan outlet, and becomes clean air after further filtering through the high-efficiency filter and is discharged into the atmosphere. The carbon ash adhering to the outer surface of the filter element is separated from the adhering surface by high-pressure air blowing or vibration of the vibration motor, and naturally settles into the carbon ash collecting container below the filter element, and the carbon ash collecting effect is unstable.

[0006] Therefore, it is necessary to provide a novel carbon ash collecting device of DPF pneumatic purging cleaning equipment to overcome the above defects. UTILITY MODEL CONTENTS
