MULTI-CYCLONE DUST COLLECTOR

Industrial pre-filtration battery with multi-element configuration and smart vortex technology

Next-generation mechanical separation units for the high-efficiency removal of dust, microparticles and airborne matter from the air arising in various industrial processes. Usually designed for limited ceiling height, this system performs continuous pre-filtration on the centrifugal-force principle without needing moving filter elements. All collected particles are safely stored in special dust hoppers with optimised sealing.

WORKING PRINCIPLE

High-speed dust-laden flow intake — tangential gas inlet: the process-origin dust-laden gas flow is forced into or drawn through the special-geometry tangential inlet in the upper part of the cyclone body at high speed. Centrifugal force and secondary-flow wall-flinging — twin
vortex and centrifugal separation: the gas, given a circular acceleration in the cylindrical body, rotates and advances down into the conical part; by the strong centrifugal force, the dust particles denser than air are separated from the gas and flung to the body walls; striking the wall and losing speed, the solids are carried by a downward secondary flow into the lower dustcollection hopper. Clean-gas outlet via the inner-vortex core — coaxial discharge: the gas flow, fully cleared of dust molecules, rises through the inner vortex (vortex core) at the cyclone’s centre and is safely exhausted from the system through the coaxial outlet pipe at the top.

KEY ADVANTAGES

• Group-cyclone layout for large flows. Depending on the process air flow and the severity of conditions, the systems can be produced in combination — as groups of 2, 4, 6 or 8 cyclones; such group systems can clean huge gas volumes from a single centre.

• Spiral and common-hopper flexibility. Per the project’s aerodynamic requirements, it can be configured with a spiral (scroll) air-flow hopper or a common cleaned-air collection hopper; it mounts flexibly on the suction (negative) or discharge (positive) side of the fan.

• Zero spare-part and filter-element cost. The body contains no fabric bags, cartridges or electro-mechanical moving parts; this gives low maintenance cost and continuous-operation suitability with no part wear, filter blinding or clogging risk.

• Engineering design criteria. Net cleaning efficiency is designed precisely to the selected model design, cyclone type and the plant’s particle-size distribution. Base parameters: volumetricflow management — gas flow (m³/h) and line pressure loss (P); particle characteristics — dust-load concentration (g/Nm³) and micron-level particle-size distribution; thermal and positional calibration — gas temperature and mounting position (suction/discharge-line optimisation).

• Sectoral applications. Food, grain and agricultural industry — dust-extraction lines of flour, semolina, starch and feed mills; heavy industry and building materials — cement, gypsum and mineral building-material production; mechanical processes — woodworking, furniture plants, metalworking/grinding; chemistry and petrochemicals — chemical, polymer and plasticgranule processes.

ENGINEERING NOTE

The Multi Dust-Collector Cyclone is a compact parallel-flow engineering developed to avoid the huge pressure losses and floor-space occupation that large air volumes would create in a single vertical cyclone. Splitting the gas flow equally into 2, 4, 6 or 8 parallel-connected smalldiameter cyclones radically raises the centrifugal acceleration (v²/r). Reducing the cyclone radius (r) multiplies the separation force on micro-particles, allowing high capture efficiencies to be reached stably and steadily even without using bag filters.
