Definitions
- the invention pertains to a device at cleaning a particulate filter according to further details set out in the preamble of the enclosed patent claim 1, and a cleaning system for a particulate filter, where the system comprises such a device.
- a silencer e.g. in a cargo vehicle with a diesel engine, today often comprises a particulate filter for exhaust aftertreatment.
- the particulate filter is intended to catch soot particles which are later oxidised into ash.
- a silencer is mounted primarily with regard to available space in the vehicle and without taking into account that the silencer should be dismantled easily, or be easily accessible when serviced. This entails difficulties in connection with dismantling, or accessing the particulate filter when the particulate filter is serviced and cleaned. Similar problems also occur in cases where the engine is arranged in other applications than in a vehicle, e.g. if the engine is used for industrial or marine purposes.
- the particulate filter in the silencer may need to be dismantled in order to be replaced or cleaned of deposited ash, and, in connection therewith, the silencer also usually needs to be dismantled at least partly. This dismantling may become considerably difficult since the silencer may weigh between 100 to 150 kg and is not always easily accessible.
- the particulate filter itself may also be difficult to dismantle since it may be tightly attached to the silencer, and in particular since it may be difficult to dismantle the particulate filter if accessibility to the particulate filter is limited.
- the particulate filter needs to be replaced or cleaned at certain intervals since accumulated ash increases the back pressure in the exhaust system, which entails increased fuel consumption, for instance.
- the replacement or cleaning of the particulate filter takes place in connection with service, which typically entails dismantling of the silencer and the particulate filter with approximately one year's interval.
- service typically entails dismantling of the silencer and the particulate filter with approximately one year's interval.
- replacement or cleaning of the particulate filter may need to be carried out at even shorter intervals. It is thus significant that the particulate filter may be replaced or cleaned easily.
- a significant problem identified with today's replacement of particulate filters is thus the difficulty in dismantling the silencer in order to dismantle the particulate filter, and/or to dismantle the particulate filter itself.
- An additional problem identified in connection with this is to be able to clean the particulate filter carefully and simply, and without the need to dismantle the particulate filter from the silencer.
- WO 2008/054262 A1 describes an example of how cleaning a particulate filter in a silencer may occur without the filter having to be dismantled from the silencer.
- US 7716922 describes how purging of a particulate filter may take place on site in a vehicle.
- One objective of the present invention is to provide a solution for cleaning of a particulate filter arranged inside a silencer without the silencer, and thus without the particulate filter, having to be dismantled from its position.
- An additional objective of the present invention is to provide a solution for cleaning of a particulate filter which ensures that it may occur in a simple and careful manner.
- the invention pertains to a device for cleaning of a particulate filter in a silencer for a combustion engine.
- a combustion engine arranged in a vehicle, an engine for industrial use or an engine for marine use.
- the device comprises a disc device adapted to be arranged in connection with a mounting opening for the particulate filter inside the silencer in order to shield off one outlet end of the particulate filter.
- the disc unit has an opening intended to let in air in order to clean the filter through flowing in one direction, backwards, opposite to a normal flow direction when used.
- the device is intended to be used in combination with a suction device, which is arranged to suck air backwards through the opening, i.e. through a limited part of the particulate filter, so that cleaning is only carried out for a limited part of the filter at a time.
- a suction device which is arranged to suck air backwards through the opening, i.e. through a limited part of the particulate filter, so that cleaning is only carried out for a limited part of the filter at a time.
- the objective of the device is for neither the silencer nor the particulate filter having to be dismantled for cleaning of the particulate filter, but that the particulate filter may remain installed in the silencer in connection with cleaning. Time and work with unnecessary dismantling of the particulate filter for cleaning or replacement is thus saved. This entails reduced costs of service where unnecessary dismantling of the particulate filter is saved; lower costs since no filter is replaced, not even for a replacement filter, and simpler logistics compared to a replacement system.
- the device is also easy to install and dismantle, even in the event of limited accessibility to the particulate filter, since it is compact, and easy to use.
- the disc unit has an edge side at the opening which comprises at least one pressure means element, such as a compressed air nozzle adapted to lead out the detergent, such as compressed air, along the edge, where the pressure means element is adapted to be connected to a pipe for the detergent, such as compressed air.
- at least one pressure means element such as a compressed air nozzle adapted to lead out the detergent, such as compressed air, along the edge, where the pressure means element is adapted to be connected to a pipe for the detergent, such as compressed air.
- the particulate filter is cleaned, by compressed air being pressed backwards through the particulate filter and transporting away loose particles, such as ash that has accumulated in the particulate filter. Likewise, the compressed air loosens particles caught in the filter.
- the invention pertains to a cleaning system for a particulate filter inside a silencer in a vehicle.
- the cleaning system comprises a device for cleaning of the particulate filter according to the invention, and a suction device.
- the cleaning system has, in addition to the advantages specified above for the device, also the advantage that the existing system for exhaust extraction may be used.
- Figure 1 shows schematically a perspective view of a silencer 3 for a combustion engine.
- the silencer 3 is arranged in a chassis of a heavy goods vehicle and is intended to be comprised in an exhaust pipe from the combustion engine.
- the silencer may, alternatively, be comprised in many other contexts where a silencer for a combustion engine is used, e.g. for industrial purposes and for marine use.
- a silencer designed typically for a vehicle is displayed, such as a heavy goods vehicle, e.g. a cargo vehicle or a bus.
- the silencer is substantially square where each side is around 700 mm.
- a particulate filter 2 such as a diesel particulate filter (DPF) is arranged inside the silencer 3.
- the silencer 3 is shown schematically with an exposed particulate filter 2 with an outlet end 6 and a mounting opening 5 for connection of a device for cleaning of the particulate filter 2.
- a hatch cover (not shown in the figure). This hatch cover may be assembled with fixture elements such as screws, or a quick fixture for quick assembly/dismantling.
- the particulate filter 2 is only shown schematically assembled in the mounting opening 5 and certain parts are only shown principally.
- additional equipment for exhaust aftertreatment may be arranged inside the silencer 2, e.g. a diesel oxidation catalyst (DOC) arranged upstream of the particulate filter 2, and/or a catalyst for selective catalytic reduction (SCR-catalyst) of nitrogen oxides, arranged downstream of the particulate filter 2.
- DOC diesel oxidation catalyst
- SCR-catalyst selective catalytic reduction
- the silencer is shown as exposed but is suitably assembled, or only partly dismantled, e.g. pulled out in a service position, from its normal position for use, in the vehicle's chassis.
- the silencer is, however, dismantled from the exhaust pipe on an upstream side of the silencer, i.e. on an inlet side (hidden in this figure).
- the fixture elements on the silencer to fasten the silencer on the vehicle's chassis are only showed schematically.
- Figure 2 shows a view from the front, and Figure 3 a view from the side in cross-section, of an embodiment of a device 1 for cleaning of a particulate filter arranged in its normal place for use at a silencer, e.g. the silencer 2 displayed in Figure 1 .
- Figure 2 shows schematically a visible part of the particulate filter's outlet end 6 on which the device 1 is arranged for cleaning of the particulate filter 2.
- the particulate filter 2 is here exposed for cleaning, in accordance with the description above in connection with Figure 1 .
- the device 1 comprises a disc 4, in this embodiment substantially circular, which is adapted to be arranged in connection with the mounting opening 5 in order to screen off the particulate filter's outlet end 6.
- Schematically visible channels in the particulate filter 2 are shown as a grid with solid lines.
- the disc 4 has an opening 7 intended to let in air through the channels which open toward the opening 7, while other parts of the disc 4 cover the other channels of the particulate filter and substantially prevent air flowing through.
- the opening 7 is thus intended to let in air through only a limited part of the particulate filter 2.
- the disc 4 is adapted, suitably designed, so that it fits inside the mounting opening 5 in terms of size, with a suitable clearance for the mounting opening 5 for easy mounting/dismantling and fastening, with the disc 4 rotatable in the mounting opening 5, but still with a surface covering the outlet end 6 of the filter in a suitable manner over the entire exposed filter surface (corresponding to the outlet end 6) and sealing against this in a suitable manner.
- the device 1 is designed as a substantially circular, in the mounting opening 5 rotatable, apertured plate, where the opening 7 is sector-shaped with a bow-shaped outside along the line named D in the figure.
- Potentially additional sealing means such as a gasket, may be arranged on the disc 4, suitably on the surface turned toward and covering the outlet end 6.
- the gasket is then suitably arranged inside an outer edge area of the disc 4 so that the gasket does not block any filter channel but still seals.
- the disc is manufactured of suitable material, such as steel or aluminium, and with suitable dimensions, e.g. a diameter of around 200 mm and with a thickness of 2-10 mm.
- the opening 7 has a radially pointed edge side 8 comprising at least one pressure means element 9, adapted to lead detergent with an overpressure, suitably compressed air or other compressed gas, along the edge side 8 and adapted to connect to a pipe 9a for pressure means, suitably compressed air or another compressed gas.
- valves 9b may be arranged between the pipe 9a and the pressure means elements 9.
- the pressure means elements 9 are adapted to purge the particulate filter 4 with compressed air, so that particles that are caught in the filter channels are released by the compressed air and then may be sucked through the particulate filter 2 backwards by a suction device arranged at the opposite end of the particulate filter 2.
- the pressure means elements 9 are designed as several compressed air nozzles, arranged along and debouching on the bottom of the disc 4, in the vicinity of the edge side 8.
- This edge side is here a straight radially pointed side of the sector-shaped opening 7.
- the compressed air nozzles on the other hand are arranged somewhat displaced in relation to each other in order to overlap each others' working areas when the disc 4 turns in the mounting opening 5, in order to thus ensure that the outlet end's 6 entire end surface is subjected to compressed air as the disc 4 rotates.
- one of the compressed air nozzles 9 is arranged with a mouth around a central area R of the disc 4 in order to ensure that the entire filter's outlet end 6 may be subjected to compressed air.
- the nozzle 9, which is arranged around a rotation centre R for the disc 4, is somewhat larger than the others which have substantially the same size.
- the compressed air nozzles 9 may have the shape of narrow columns which extend along the edge side 8.
- the device 1 for cleaning the particulate filter 2 also comprises the said suction device which is arranged to suck air through the channels of the particulate filter in a direction which is opposed to the direction of the exhausts when the combustion engine is operating.
- the suction device is arranged at the opposite side of the particulate filter 2 to the side at which the above disc 4 is arranged.
- the suction device is connected so that the entire particulate filter's end surface is subject to the suction device's underpressure. In practice, it is usually possible to achieve this by connecting the silencer's inlet to the suction device, suitably by loosening a joint of the exhaust pipe and connecting the silencer's inlet to the suction device.
- the disc 4 In order to regulate the flow of purifying air through the particulate filter 2, the disc 4 is equipped with a sector-shaped pulling hatch 10, which is arranged in a rotatable manner (shown with a double-headed arrow 15), so that it covers the opening 7 fully or partly or not at all.
- the size of the cleaning surface (which substantially corresponds to the surface of the opening 7) may thus be controlled.
- the risk that all ash comes off at the same time is thus reduced, and a higher speed in the gas flow which transports the ash away is also achieved.
- the surface of the draft regulator 10 is suitably somewhat larger than the surface of the opening 7 in order to facilitate shutting the opening 7 completely.
- the draft regulator 10 may be manufactured with the same material and thickness as the disc 4 otherwise, but is suitably manufactured with thinner material, e.g. thinner plate, for better manageability. It may be pivoted parallel to the disc 4 with a suitable fixture, e.g. pivotally fastened in a narrower part of the sector-shaped draft regulator 10.
- the disc 4 comprises fastening elements 11 designed to fasten the disc 4 rotatably at the mounting opening.
- the disc 4 may with the help of a suitable hand tool be rotated easily by a mechanic, so that the opening 7 is brought to assume different rotational positions, following which different parts of the channels of the particulate filters may be exposed for cleaning.
- the fastening elements 11 may be fastened to bearing elements 12a, such as rolling bearings, to the centre 12. These fastening elements 11 are suitably adapted to existing fastening elements, e.g. recesses, in order to fasten the cover (which is not shown) which is mounted over the filter 2 in a ready position of use, i.e. where the filter 2 is not exposed for service such as cleaning.
- the fastening elements 11 may alternatively comprise fastening elements including screws or similar.
- the device also comprises, according to an alternative embodiment, a central shaft 12, around which the disc 4 is rotatably arranged with a bearing element 13.
- the central shaft 12 comprises one or several pipes to the elements for detergent, typically, compressed air nozzles.
- the central shaft 12 is then suitably equipped with a suitable connection element to connect to a compressed air source to the disc 4, which in turn contains channels to the different nozzles. These channels may suitably be designed as drilled channels or closed tracks in the disc 4.
- the device allows, through compact design and a low handling weight, typically between 0.5-2 kg, a good ergonomic position for the person or persons who carry out the cleaning of the particulate filter on site in the silencer or who mount/dismantle it.
- the device 1 By arranging the device 1 during use in different positions, so that the opening 7 is moved when the mounting opening 5 is rotated, over the entire filter's outlet end 6, i.e. over its entire end surface, the entire particulate filter is cleaned carefully without e.g. large soot flakes or other particles coming off in an uncontrollable way during cleaning.
- This solves, or at least limits, the problem with the risk that other sensitive equipment for exhaust aftertreatment may be damaged, even though it remains mounted while adjacent particulate filters are cleaned. Problems with soot or dust being spread in an undesirable manner in the service premises when cleaning is carried out are also solved, which improves comfort for the service staff.
- nozzles for clean compressed air or nozzles for a suitable detergent mixed in the compressed air instead of nozzles for clean compressed air or nozzles for a suitable detergent mixed in the compressed air, different combinations of compressed air nozzles and nozzles for a detergent or different detergents are used. If different nozzles for different detergents are arranged, the number of pipes 9a is adjusted according to these.
- a joint pipe 9a with one or several valves for feeding of different detergents may also be arranged according to other alternative embodiments.
- the pipe 9 runs through a central part, e.g. a hollow central shaft 12, of the disc 4 and is, when used, connected to e.g. a compressed air source (not shown in this figure).
- FIG. 4 shows schematically the more detailed embodiment of a cleaning system 20 comprising a device 1 for cleaning of a particulate filter, according to the above description, and the suction device 21 which is comprised in the device.
- the cleaning system's 20 suction device 21 is connected to an inlet 3a to the silencer 3.
- the suction device may be of any suitable type, e.g. an existing exhaust suction 24 with a dust or particulate trap 25, such as a cyclone, a fan 23 and, potentially, a filter 22.
- the dust trap 25 is suitably connected between the inlet 3a and the suction device 21 and functions like a collecting device for the particles which are cleaned from the particulate filter.
- an inlet 3a of a silencer in a cargo vehicle typically has a diameter of around 110 mm
- other suction devices may easily be connected to the inlet 3a with standardised pipes and connections.
- the fan 23 is suitable to regulate the air flow through the particulate filter.
- the silencer 3 is shown only schematically and in an inserted position in the vehicle's chassis, but depending on e.g. the vehicle type and placement of ancillary equipment, the silencer may also be partly pulled out, e.g. in a service position, from the vehicle's chassis.
- the inlet 3a is shown in this embodiment dismantled from the exhaust pipe.
- the silencer When the silencer is pulled out, the fastening device arranged in slide rails and support rails is unscrewed. Subsequently, the silencer 3 may be pulled out.
- the silencer is then not entirely outside the vehicle's chassis, since it is not necessary to carry out service measures. Since the silencer's weight is between 100 and 150 kg it is desirable not to have to handle it unnecessarily.
- the problem with limited access to the particulate filter is solved without having to remove the filter from the silencer.
- other peripheral equipment such as other exhaust aftertreatment equipment, e.g. a urea tank for SCR, may be mounted while the particulate filter is cleaned.
- the device is particularly suitable for a silencer in a cargo vehicle, but also in a bus, where it might be attached on the side of the rear end of the bus, and thus often difficult to access.
- the particulate filter may be cleaned at a significantly lower cost than what has hitherto been possible. Alternatively, the cleaning may be carried out much more often, which leads to reduced emissions, since the particulate filter is significantly cleaner during a longer operating time than what has hitherto been possible.
- the ash contribution in the back pressure may thus be reduced already before an alarm is sounded that the filter needs to be cleaned. Even if the filter may only be cleaned up to e.g. a 95% cleaning degree, this means that the back pressure may be kept low during a much longer period since the filter is cleaned more often than what is currently possible with conventional methods. The fuel consumption for the combustion engine is thus reduced.
