1GENERAL
In a principle, the data sheet for BUCKET ELEVATOR is composed of a data sheet and a sketch form. But if the data sheet is enough to describe the structure and the size of it, sketch sheet can be omitted.
2SHEET NO. AND REVISION NO.
A Sheet number is admissible up to 3 pages as the number of data sheet itself. The first revision no. shall be "0" and the new revision no. 1,2,3,... shall be given in order under the same rules for the drawings.
3PROJECT INFORMATION.
The customer item is described as the full name as possible, and the location item as location name and nationality, the service item as its system or process.
The REQ'N NO. is described by the mechanical engineering team at the requisition issue, so it is followed up after the requisition issue.
3.1 SupplierIt is determined after purchase contract of equipments, so its item is described after confirming 1st vendor print.
3.2 No. ReqdIt means the number of the equipments and the unit. If required, the stand-by It is determined after purchase contract of equipments, so its item is described after confirming 1st vendor print.
4OPERATING CONDITIONS
Mainly the data related with the process is described fully.
4.1 Material HandledIt is the feeding fluid to the bag filter. If there are multiple materials, their analytical method is needed. Each the component of raw materials is expressed as %WT or % VOL. If the space is not enough, mark the Remark No. at the blank and describe at the below remarks space.
4.2 Density (Bulk/Real)
For transportation of raw material, generally bulk density is needed. But the bag filter is to separate the mixed particles, the bulk and real density both are specified.
4.3 ViscosityIn case of attachable materials, they are classified. But for reference, it is specified.
4.4 TemperatureIt means the temperature feeding to the bag filter. If materials are not handled at the prior process, it can be specified as ambient temperature.
4.5 Moisture ContentIt means the fluid's containing moisture contents, is necessary to the filter design.
4.6 Particle ContentIt means the particle contents in feeding fluid to bag filters. As it is related with the design, it should be specified.
4.7 Particle Size DistributionIf there are various sizes in the feeding fluid, its distribution is specified by size. If the particle distribution is uneven, it is noted as %WT or %VOL. In that case, remarks no is noted and it is noted below remark space in detail.
4.8 Angle of ReposeIt means the angle of the repose, used hopper volume design mainly. It is necessary or referable according to the kinds of the equipments. Here, it is to be used to the hopper design at the bottom of the casing in the back filter.
4.9 Particle Size (to be removed)
It means the size to be eliminated. Must consider the environmental regulation.
4.10 Dust loading (to be removed)
It means the dust contents filtered in the bag filter. So it can be contents in the fluid.
4.11 Pressure Drop (Max. available)
It is about 100 mmH2O at the operating condition because of pressure drop at the filter.
4.12 Flow rateIt means the ability and capacity of handling; the capacity is showed at the normal and design item on the data sheet. The normal item must be described. Design capacity can be the rated capacity in the equipment detail design and motor power calculation to vender.
4.13 Suction and Discharge PressureThey are the inlet and outlet pressures of the bag filter respectively. The discharge pressure is normally ATM.
4.14 Operating TypeOperating type is composed of continuous or intermittent and auto start/stop or manual start/stop as showed on the data sheet. If the special operating type, it is noted on the remark space. Whether start/stop type is automatic or manual, it is necessary to confirm the supply of start/stop push button box. For all equipments at the start of project, it is necessary that the determination between form each vendor and from instrument engineering team. If automatic, it is necessary to confirm the needs of remote switch on the local push button box. If continuous on-off operation, it is noted in the remarks space. (For example, on-off cycle time: 3min.)
4.15 Operating TimeIt is expressed as operating cycle, means the operating time per day. It is related with the plant operating time of client. If 2-shift, it is 16Hr/day. If 3-shift, it is 24Hr/day.
4.16 Material PropertiesIt means the chemical and physical properties of the transported material as an engineering view. It is good to select the related property on the data sheet.
If there is need to express the power of property, select it and it is reasonable to mark the high or severe at the blank. If multiple properties, select and mark multiple options. If no listed properties, select other option, and describe it.
4.17 InstallationIt means the construction location of equipments on the lay out, either indoor or outdoor. If extra condition like under roof, make a note.
5. CONSTRUCTIONS
It shows the equipment structure and specification. Only process options are marked, the others are marked by vendor.
5.1 Design Pressure and TemperatureBecause the bag filter only removing the dust equipped on the hopper is contacted with atm., design pressure is not considerable. But if it is equipped in the process, the temperature and pressure are to be considered.
5.2 Corrosion AllowanceThe casing of the bag filter is mainly carbon steel, so corrosive allowance should be considered.
5.3 ThicknessIt means the thickness of casing fixed up by vendor.
5.4 ConnectionsThe type and size of the connections between suction and discharge of body are specified.
5.5 Filtering AreaIt means the surface area of filter where the fluid goes through, and based on vendor standard.
5.6 FilterIf the type of filter options is fixed, the others of filter options are specified by vendor.
5.7 Bag Cleaning MethodIf the filter is operated for a long time, the dust is attached to the filter surface. So, after the power is removed, the filter can be used continuously. If continuous operation, the air jet pulse type is applicable, and if intermittent operation, the motor shaking type is applicable.
5.8 Dust Removal MethodIt means the method the remove the dust pile up at the bottom of the filter.
5.9 Cycle TimeIt means the air pulse cycle or shaking cycle, and is fixed up by vendor.
5.10 InsulationIf necessary, fix up the whether insulation is needed or not.
5.11 Overall Size and WeightIt is informed by vendor.
6MATERIALS
It is general that the materials are fixed according to the properties of the raw material and the operating purpose. The material contacted with raw material on process should be specified. After at least, the material of the filter and casing are fixed up, the others are fixed up by vendor. The selection of the materials is fixed by referring the material properties on operating condition.
7DRIVER
If normal, supplied-by/mounted-by is fixed by vendor. Because the things with drivers are fixed by other detail associating teams, the driver needs not to be fixed by process engineering team. So no. needs no. marks.
8ACCESSORIES
Because the supply scope of accessories is related with the supply scope of the equipments and fixed up according to operation/system. it can fixed up at the process data description possibly. They are specified if fully explainable as process requirements and special requirements. So, it is possible that the detail associated teams select them.
8.1 Rotary Valve with RotorThe its requirements are fixed up by dust removal method.
8.2 Local PanelIf no special case, it is always supplied.
8.3 Setting (Anchor) Bolt and NutsMust supply them.
8.4 Air Control UnitIf air pulse type, consider its requirements.
8.5 Platform, Ladder, HandrailThey are considered according to the height of equipment. Even though enough high, it can be not equipped.
8.6 Air KnockerWhen the dust assembled at the bottom of bag filter is removed, if the dust is very attachable, the air knocker is equipped for the fluid to flow well.
8.7 Differential Pressure IndicatorBecause It is for the decision of the replacement time with the differential pressure, it must be equipped.
8.8 Screw ConveyorIn case of the big-sized bag filter, it is equipped to be remove the dust easily.
8.9 Access DoorsThey must always be equipped on the body.
8.10 Dust Box with GateWhen the dust removal type has the dust box, the dust box with gate is applicable.
8.11 TimerMust always supply it.
8.12 Level SwitchIn order to know the level of dust accumulated at the bottom of the bag filter and remove it, the level switch is equipped. But it not always be necessary.
9REMARKS
Remarks are for the description of requirements if data sheet format is difficult and impossible to describe. Also if there are the added special process requirements.
