While the choice of a dust collection technique<\/strong> is guided by the size of the particles emitted, their physico-chemical properties, and their impact on operators and the environment, other criteria are involved in the choice between a fixed or mobile dust collector<\/a>, and between centralization or localization of the dust collection system. These criteria depend on the production context: the industrial sector, the size of the production unit, the point in its life cycle, the production processes, the legal constraints governing its operation, the financial balance between budgetary constraints and the investment and operating<\/strong> flows of the dust collector<\/strong>, etc. Each case is unique. The criteria are numerous! A first approach will enable you to clear the ground!<\/p>\n\n

Context of choice in a fixed or mobile, central or local dedusting system<\/h2>\n\n

A fixed dedusting unit covers all the production unit’s workstations<\/strong>. It will handle a large volume of dusty air, whatever the concentration of dust emitted. <\/p>\n\n

Conversely, investment in a mobile dust collector is part of a localization strategy. Its processing capacity is usually limited to the workstation. Its mobility means it can be used in a variety of locations<\/strong>. <\/p>\n\n

Other dust collectors meet intermediate requirements. For example, a fixed dust collector located <\/strong>at a workstation could be a permanent solution for a small structure, or a complementary solution for a large production unit that would require the costly upgrading of a dust collector. A mobile dust collector can also serve several workstations simultaneously, on a construction site or in a small production unit.<\/p>\n\n

Since there are so many use cases, we’ll look at the criteria for a fixed power plant and a mobile filter<\/strong>; we won’t look at the intermediate contexts, since the criteria differ not in nature but in degree.<\/p>\n\n

Level and duration of investment, purchasing process <\/h2>\n\n

Theacquisition of a centralized dust collection system <\/strong>requires a significant investment of time and money. It requires a preliminary study of the production system, detailed design of the dedusting system for integration into the production system, manufacture and installation. This is a strategic investment that can be considered at certain phases in the life cycle of an industrial facility: the creation of a large, specialized production unit, when it is being extended, or when the production system is being redesigned. <\/p>\n\n

The investment in a mobile dust collector is much lower. The acquisition cost does not include any work on the building<\/strong>, nor any loss of production due to the temporary stoppage of production to carry out the installation. The industrialist spends less time on the purchasing process, which can be delegated to the shop floor. <\/p>\n\n

In some cases, the purchase of a dust collector can be preceded by a lease to secure the investment. Furthermore, the rental of mobile equipment can address a temporary need (e.g., a temporary worksite, the repair of a component of the production system <\/strong>leading to the emission of harmful or explosive particles<\/a>, …)<\/p>\n\n

The acquisition of mobile dust collectors is part of a gradual investment program in line with changes to the production system. This investment strategy anticipates changes in the industrial sector, developments in state-of-the-art production and dedusting techniques, and changes in legislation. In the event of a centralized dedusting system<\/strong> being upgraded as a result of production system expansion, the initial investment can be retained and topped up by investing in mobile dedusters.<\/p>\n\n

Prospects for development of the production system <\/h2>\n\n
\"dustomat<\/figure>\n\n

Manufacturers consider the solution of centralized dedusting when their production system is evolving over the long term, and is specialized in one type of production. A centralized dust collection system is designed for a specific use. It is planned and manufactured according to the requirements of the production system at a given time. Anychange in the configuration of the production system<\/strong> (new machine, new location, expansion of the production unit) will trigger a reconfiguration of the dedusting system (resizing of the piping network, filter). In some cases, this may mean a complete overhaul of the investment, if the modularity of the filtration module or the variability of the ventilation were not taken into account in the design phase, due to budgetary constraints <\/strong>. <\/p>\n\n

Investing in a mobile dust collector <\/strong>is part of a strategy to decentralize the dust collection system. The filter module with filtered air discharge is located as close as possible to the machine. This strategy is based on the prospects of short- to medium-term adaptability and evolution of the industrial tool, versatility in the use of the dust collector, a discontinuous need for the use of a dust collector at a workstation<\/a>, and rapid obsolescence of the technologies used by the production system. The manufacturer considers the purchase of a mobile dust collector when promoting flexible organization of the production system. For example, a mobile dust collector will follow the change of location of a production unit when the manufacturer reconfigures his production system. Theacquisition of a mobile dust collector <\/strong>can also accompany the expansion of production facilities. This involves completing the initial configuration of the dedusting system (central unit or fleet of mobile dedusters).<\/p>\n\n

Impact of dust collection system installation time on the production system<\/h3>\n\n
\"obnex2\"<\/figure>\n\n

Installing a fixed, centralized dedusting system requires<\/strong> temporary shutdowns of the production system, thus consuming production time. Installation often involves time-consuming building adaptation work (e.g. reinforcing load-bearing foundations, penetrating load-bearing walls, penetrating ceilings, adapting electrical and compressed air networks, etc.). To this must be added the time required to set up a complex collection and piping network, which is necessary to comply with the standardized suction speeds at each unit, and the transport speeds of the collected dust.<\/p>\n\n

The installation of a mobile dust collector<\/strong> does not consume production time, as it does not require any temporary shutdown of the production system. Installation is as simple as positioning the unit and connecting it to the electrical and compressed air networks. The dust collector is positioned as close as possible to the production equipment. Piping is reduced to a minimum. There’s no difficulty in accompanying a change in workstationinstallation<\/strong>.<\/p>\n\n

Impact on production space configuration and choice of fixed or mobile dust collector<\/h3>\n\n

The overall dimensions of a centralized dust collection system are calculated by adding together the volumes occupied by: the collection modules<\/a>, the dust transport network, and thecentral filtration and recovery unit<\/strong>. The centralized filtration unit takes up so much space that an internal location is often considered, either in a specialized room, near an external wall inside the production unit, or in an external location. The location of a dedusting unit is a compromise between the configuration of the production area, the distance between the suction devices and the central filter, and the size of the pipework. The location of the piping network in the production area must take into account the space required for machine intervention in the event of a breakdown or machine relocation<\/strong>.<\/p>\n\n

A mobile dust collector takes up very little space compared with a fixed dust collector. The unit’s size and mobility enable it to be placed close to the workstation or machine. This placement eliminates problems of pipe network congestion. Spatial constraints will be local, linked to: the volume available between the workstation and adjacent installations<\/strong>, the dust collection device and its proximity to the source of emission, the different positions of the worker and his movements while operating. The ease with which a mobile dust collector can be maneuvered helps to meet these requirements. <\/p>\n\n

Continuity or discontinuity of the production process in the choice of centralized or localized dedusting<\/h2>\n\n

A central filtration unit <\/strong>generally corresponds to the continuous dedusting needs of a group of machines, each with its own specific extraction system. A centralized unit is designed for continuous, simultaneous dedusting of all production system operations. It is able to deploy a very high airflow and filtration surface area, capable of absorbing peak dust emissions. When a workstation is not in use, the air intake does not stop. Under-utilization leads to unnecessary energy consumption<\/strong>.<\/p>\n\n

A mobile dust collector can be adapted to meet both continuous and occasional dust removal needs. Versatile, it can successively dust several dust-emitting workstations over a limited period of time, or several temporary worksites<\/strong>. It can accompany a mobile workstation, or multi-point work on a large part. <\/p>\n\n

The use of several mobile dust collectors enables manufacturers to adapt their dust collection system to the variability of emissions and the diversity of particles emitted by the equipment in their production system. Several dust removal techniques can be used in parallel, depending on the workstation. It is also possible to combine local filtration<\/strong> (suction at source) and general filtration (ambient suction) using mobile devices.<\/p>\n\n

The noise level added by the dedusting system in compliance with regulations<\/h3>\n\n
\"capture<\/figure>\n\n

The noise level of a dust collector in operation<\/strong> comes from the fan noise (blades, motor), the cleaning noise (shaking, compressor, compressed air pulsation…).<\/p>\n\n

A dust collector operates continuously, emitting a noise proportional to its power. Placed inside the production unit, it must meet regulatory requirements for daily noise exposure levels for operators. This means either soundproofing or placing it in a specific room with sound insulation. Placed outdoors, it is subject to the legal constraints on noise pollution associated with industrial activities, particularly if the production<\/strong> unit is located in a residential neighborhood<\/strong>. Filter soundproofing includes fan soundproofing (acoustic hood, silencer) and filter cleaning soundproofing (filter lining with removable acoustic panel).<\/p>\n\n

The noise level of a mobile dust collector is around 80 to 90dB. This noise is added to that of the workstation. This accumulation may require individual protection against noise to take account of regulatory requirements on the worker’s noise environment<\/strong>.<\/p>\n\n

Energy consumption of dust collection system<\/h3>\n\n

The permanent operation of a dust collector is not compatible with a temporarily unused workstation. Energy is inevitably wasted, as the intake air does not need to be dedusted. If the central unit is positioned outside the building<\/strong> and the air is discharged to the outside, thermal energy consumption will be added, linked to the temperature differential between ambient air and outside air. <\/p>\n\n

A mobile dust collector can be used on demand. It operates only during the operating time of the device with which it is paired to filter its emissions. Energy consumption is limited to the duration of use<\/strong>. As the deduster discharges clean air back into the production unit, there is no thermal energy consumption associated with the dedusting process.<\/p>\n\n

Dust collection system maintenance<\/h3>\n\n

The mechanical parts in motion are essentially located in the filter of a central dust collector. Maintenance is mainly carried out at the filter location. Pipework checks will be more complex. In the event of failure of a production unit, dependence on a single filtration source results in complete shutdown of the production unit, or of part of it if the piping network<\/strong> has been designed with variable ventilation. Filter failure inevitably triggers production stoppage. <\/p>\n\n

The mobile dust collectors are distributed throughout the production unit. Organizing maintenance is less straightforward, since it takes place in several locations, which multiplies the number of checks. On the other hand, the failure of a production unit<\/strong> does not affect the dust removal of other units. The breakdown of a mobile dust collector can be temporarily resolved by renting a similar one.<\/p>\n","protected":false},"excerpt":{"rendered":"
