Definitions
- the invention relates to a method and a device for reduction the dust deposit on a paper machine drying hood.
- the invention has therefore set itself the task of a method and To create device with which the risk of fire and explosion can be significantly reduced by the dust.
- An advantageous development of the invention is characterized in that that the fresh air transversely to the web running direction towards the drive side of the Paper machine is blown out. This leads to lower loads of operators on the operator side of the paper machine.
- a favorable embodiment of the invention is characterized in that that the blow-out amount is adjustable, alternatively or additionally the blow-out direction can be adjustable.
- the adjustability of the Quantity and / or direction can be specific to the local and plant-specific conditions are particularly well received.
- a favorable further development of the invention is characterized in that that more fresh air on the insulated surface of the expansion joints and / or piping is blown.
- the invention also relates to a device on a paper machine drying hood to reduce dust deposits.
- This device is according to the invention characterized in that at the top of the Paper machine drying hood at least one blow-out slot for Air blowing is provided, the slot advantageously in the insulation the hood can be arranged.
- a favorable further development of the invention is characterized in that that the at least one slot extends in the machine direction.
- An advantageous embodiment of the invention is characterized in that that the opening of the slots is formed so that the air along the Top of the paper machine drying hood is blown.
- An advantageous development of the invention is characterized in that that the exhaust slot is open towards the drive side.
- a favorable embodiment of the invention is characterized in that that the at least one blowout slot adjustable in its cross section is, the blow-out slot alternatively or additionally in its direction can be adjustable.
- a favorable further development of the invention is characterized in that that the blowout slot in the insulation of a high temperature hood Tissue machine is provided, alternatively in the insulation the hood of a multi-cylinder machine can be provided.
- An advantageous embodiment of the invention is characterized in that that the blow-out slot is integrated with one in the insulation Air distribution system is connected.
- a special development of the invention is characterized in that that the blowout slot in one on the paper machine drying hood attached pipe is provided.
- FIG. 1 shows the view of one half of a high-temperature hood for tissue machines
- FIG. 2 a detail from FIG. 1
- FIG. 3 a schematic view of a tissue machine with top blowing the hood
- Fig. 4 a further variant of the invention analogous to Fig. 3 with integrated blow-out
- Fig. 5 the application of the invention to Zuund Represents drainage pipes of the hood.
- the half of a high-temperature hood 1 shown in FIG. 1 has one Connection 2 for fresh air injection for paper drying and one Connection 3 for suction.
- the paper is blown through Blow-out nozzles 4 and the extraction of air from the paper through slots 5.
- the fresh air supply for the blowing takes place through a nozzle 6.
- This nozzle 6 is connected to a distribution channel, which is in the insulation 7 the high temperature hood is integrated.
- the blowing out of additional Fresh air then takes place through a blow-out slot 8 on the Driver's side 9 of the high temperature hood 1 is attached. It can also a further blow-out slot 8 'can be provided which is used for blowing Drive side 10 of the high temperature hood 1 supported.
- the cleaning intervals can also be extended and the Cleaning downtimes can be shortened.
- FIG. 2 shows a detail from FIG. 1, one into the insulation 7 integrated distribution channel 13 includes.
- the air from the air distribution duct 13 flows through the blowout slot 8 on the driver side 9 of the high temperature hood 1 along the hood roof 12 in the direction of Arrow 11 to the drive side of the paper machine.
- the blow-out slot can be adjustable in its cross section and in its direction. So can be the amount of air blow out and also the flow direction be influenced in order to achieve a targeted flow.
- Fig. 3 shows a schematic view of a tissue machine with the Hood halves 1, 1 'which are steam-heated over most of the circumference Drying cylinder 14 are attached.
- the air supply for the Drying takes place through lines 2, 2 'and the exhaust air is over Lines 3, 3 'withdrawn.
- the air for blowing the top 12, 12 'of the hood is supplied via pipes 6 and out lines 15, 15 'attached along the hood halves 1, 1' Blown out openings 16.
- These blow-out openings 16 can Blow holes or blow slots.
- FIG. 4 shows a further variant of the invention analogous to FIG. 3, but with integrated blow-out. It can be seen that the fresh air for blowing Air distribution channels and the exhaust slots 8, 8 'supplied be integrated into the hood 1, 1 '. These correspond to the channels 13 and blow-out slots already shown in FIGS. 1 and 2 8th.
- Fig. 5 shows the application of the invention to supply and discharge pipes the hood.
- a cross section of a pipeline 16 is shown here, wherein the fresh air for blowing from a supply or Discharge pipe 16 arranged pipe 17 along the arrows 18 along flows along the surface 19 of the pipeline 16.
