Cartridge Dust Collector Description

“AKMAN Modular” is a modular cartridge dust collector with a built-in fan. Its cartridges are vertically positioned and cylindrical, which come are complemented by an automatic cleaning system.
The built-in fan creates the necessary air flow for efficient air cleaning. The cartridge collector is delivered in a muffled frame, it is compact, and its use is straightforward.

Reliable, cylindrical cartridges

They provide a longer filter lifetime as well as a higher filtration efficiency and, consequently, operational savings for you!

Larger filtration material area

The folded filtration material structure is very compactly designed and a single such cartridge has a filtration surface of 15-20 bags!

The most common type of cartridge

Thanks to the great popularity of cylindrical cartridges, you can quickly find the one that suits you and replace it with ease.

QUICK SELECTION BY SECTOR

How It Works

Contaminated air enters “AKMAN Modular” through an air pipe (or a gas pipe) into the dirty chamber, after which the dust particles settle onto the channeled cartridge while the cleaned air passes through the cartridge and enters into the clean chamber, after which it exits the filter outside with the help of a fan or goes back into the facility.

Specification

The Specifications depend on the package elements. For each client, we create a project based on a detailed survey about the production site and the nature of the dust.

The filter can be designed to be unconventional, depending on the client's technical task.

PERFORATED DUST CASSETTE

A perforated dust cassette can be installed in front of the filters so that the dust settles right down into the hopper and reduces the wear on the cartridges. More even distribution of gas flow along all the cartridges increases their service life and helps save on operation costs.

Modifications, Dimensions, and Drawings

A modification is a filter variation with a different quantity of modules. Adding modules entails a change in general performance, filtered air volume, size, and other specifications. “AKMAN Modular” cartridge collector consists of one or multiple modules.

The recommended performance of a single module is no more than 11,000 cfm and in order to increase the performance of the cartridge dust collector, it is required to install an additional module (see example in drawing below).

A collector can optionally be designed with non-typical size depending on the client’s technical task

Filter cartridges

We use a channeled cartridge as the filtering component. Thanks to the folded structure, the filter material is placed very compactly. For instance, a single standard cartridge of Ø12.8 in, 39 in tall has a filtering surface area of 178 ft² and replaces 15 - 20 bags.

The filter material entails a very thin (about 0.02 in), solid material with small pores. It is rated within the F7-F9 classes in terms of Eurovent’s cleaning quality standards, outperforming in this component materials usually used in cartridge filters.

The gas goes from outside the cartridge and enters and the dust particles settle on the outside part of the filter while the clean air passes inside the cartridge and leaves the filter outside.

The filter component becomes dirty every now and then and is cleaned by air impact. The concentrated impulse from the air valves shakes the cartridge filter material and the dust settles inside the hopper. Cartridge cleaning is performed without any halt in the filtration cycle.

The filter cartridges withstand a dust load of up to 2 ppm. A Cyclone will have to be placed in front of the equipment if the load is to get any more than that.

Dust Hopper and Discharge

In its standard package, “AKMAN Modular” has a conical accumulator hopper for dust and a round gate with a manual gear for opening and closing or a box on wheels.

Additional hopper package elements

A vibrator or a vibration device to prevent dust from sticking to the walls of the hopper.
Level transmitter.
Hoppers and supports according to the demands of your production site. For instance, for our client, we tailored the hopper for big bag discharge at their wood processing enterprise.
Worm hopper for continuous dumping of dust out of the hopper with a gate. Thus, the filter won't have to be halted in order to unload accumulated dust.

Captured Product Discharge

Discharging organization methods for the client to choose from:

The basic package features use of the manual method, which is done using a manual hatch which when opened manually and the dust unloads out of the dust aggregator into some volume or, when dust falls into a connected volume (box) without a hatch.The automated method: a flood gate or a double flap is used for unloading, often together with a worm transporter.
The automated method uses a gate or double dump for discharge, often along with a worm transporter.

The main distinction is manual labor which must be exerted to unload the captured product. The automated method can be combined with a production line and, for instance, the product can be returned back onto a conveyor belt.

Automatic “flood gate” (feed)

Mechanical “double flap”

Cartridge Dust Collector Management

Smart control automation ensures uninterrupted operation.

Filter control is performed using a controller or a remote control. This system works in a closed cycle, but it can be reconfigured depending on the client's needs.

We propose packaging the filter with a completely automatic control system, analysis, fire extinguishing, etc. In the standard package, a temporary controller is installed and it can also be packaged with a Siemens controller depending on your needs.

Pulse Jet System

The filter cartridges end up covered in “sticky” dirt every now and then, which increases the filters’ resistance. In order that the system works without interruption and without any variations in pressure, cartridges must be cleaned. The cleaning is done in the following way:

At the top, there are air pipes in the clean air chamber which follow from the air cleaning diaphragm valves. These valves are installed on the receivers where the compressed air is located which is used for air impact.
The air in these receivers is fed from the compressor. Every now and then, the valve begins operating, the air is fed into the tube through the valve, and then out of the tube it is distributed inside the filter cartridge with the help of nozzles.
The filtered cartridge is shaken and blasted. Then the dust falls down into the accumulator hopper.
The dust can be extracted from the accumulator hopper in three ways, depending on the technical task declared: a manual dust latch, a mechanical double dump, and an automatic gate. The standard version comes with a manual dust latch.

Pulse Jet Cleaning System Package:

Innovative development: air pipes system with a cleaning enhancer

They are either metallic or plastic. It all depends on the gas and temperature that the filter is cleaning. Nozzles are installed on the air pipes for more efficient cleaning of the filter component. A special cleaning enhancer is installed above the cartridge, which helps improve filter shaking and extends its service life.

Compressed air receiver
The receiver is what accumulates air for air projection. If there isn’t enough air, the degree of cleaning will fall, the wear on the filters will rise, and the filter’s performance will decline, since the aerodynamic resistance of the filter will increase. Thus, our receiver is designed in such a way that there is enough air for all the air cleaning cycles. The receiver has a connector on it to connect to a compressor or general factory compressed air pathway and moisture drain valve.

Air valves
All valves are certified. Our valves are specialized for filter equipment air cleaning systems.

Controller
Regeneration system control is performed with the help of a special controller that configures the quantity of impulses and the frequency of the impulses.

Differential manometer (by order)
With a manometer, cleaning of the filter not only varies in time but also in terms of how “stuffed” the cartridge gets. When the pressure falls in the filter chamber, the manometer submits a signal to the controller to initiate blowing.
