Dust Collector Description

VIEW PDF CATALOG BLIZZARD BAG FILTER RS

The Blizzard Bag Filter RS is a reliable, low-maintenance, classic gas cleaning baghouse dust collector. It works with practically any type of dust, filtering both dry coarse and finely dispersed dust. It is a compact baghouse with round bags and features gas entrance passing through shutter dampers.

High dust load of up to 120 ppm

Round type bags are installed in the filter suitable for operating under conditions of high contamination.

High operation air temperature of up to +536 ˚F

In the standard set, the filter works with air flows of up to +300 ˚F. By order, a filter can be manufactured with an operation temperature of up to +536 ˚F.

Round Bags and Shutter Dampers: Efficient Cleaning and Reliable Protection

Reduce the wear on bags and save yourself the money and time spent replacing them

Shutter dampers are installed in front of the filters so the dust settles right inside the hopper, thereby reducing the wear on the bags.

Clean the air of any size of dust

Having a shutter damper in a filtration installation allows enterprises to work with dust containing medium-sized and large particles, as they fall right into the hopper after colliding with the shutter.

Modular Design: Our Main Field of Expertise

Increase performance by adding an additional filtration module.

Bolt mounted SKD assembly is performed based on instructions, such as in furniture assembly. Without any welding or complex modulations.

Due to the modular design, delivering the filter requires no special transportation and takes less time.

QUICK SELECTION BY SECTOR

How It Works

The contaminated air enters into the Blizzard Bag Filter RS via the air duct (or gas pipe) into the dirt chamber. Large-sized dust particles are reflected off the shutter dampers. After that, the dust particles settle on the bags as the cleaned air passes through the bags and enters into the clean chamber. The purified gas exits from the filter outside or back into the facility with the help of the fan.

The filter model is suitable for most industrial sectors, including cement dust, coal processing plants, wood processing, metalworking, and others.

Specification

The performance specification depends on the package elements. We create each project customized for the client bases on a detailed questionnaire on their industrial site and the nature of the dust.

Modifications, Size, and Charts

Modification: a filter option with a different number of modules. Adding modules brings about a change to general performance, the volume of the air filtered, size, and other specifications.
The Blizzard bag filter RS filter consists of one or multiple modules.

The recommended performance for one module is no more than 18,000 cfm. Augmenting performance requires installing an additional module (example is provided in the chart below).

A filter can optionally be produced with nontypical size depending on the client's technical task.

Baghouse Design and Diagram

Movement scheme of gas inside and outside the filter

Air enters by way of the space under the bag via the gas entry flange and hits the shutter dampers, after which the air continues into the dirty chamber where the filter bags are. Such a design helps the client save on the filter diameters.
Highly charged and heavy particles are reflected off the shutter dampers located above the gas and air entry point and they fall into the hopper.
Air containing fine dust particles passes through to the bags into the dirty air chamber and then into the clean air chamber via the bags while the dust falls to the perimeter.
After that, the air passes up into the clean air chamber and exits the filter.
Located above are hatches for changing out the filter bags, which are necessary to replace, diagnose, and repair them.
An additional diagnostic hatch is located at the end of the filter.

Round Filter Bags

The Blizzard Bag Filter RS is equipped with round bags. Filters of this type are a little bigger in dimension and heavier than those with flat bags. This is due to the fact that when round bags are used, a larger internal space has to be created for the bags to be arranged in and gas dynamic laws have to be observed as well.

Round filter bags withstand a large-sized dust load of up to 120 ppm, in some cases even up to 150 ppm.

Round filter elements come in many different forms, types, and diameters. Up to 4-5 meters in length, no Venturi tube is required, and, instead, flow nozzles are used. At a length of over 5 meters, we can recommend using a variety of nozzles for more efficient filter element cleaning.

The material for filter bags is chosen on a case-by-case basis, in accordance with the technical task.

Contaminated Air Entry: Shutter Dampers

In the Blizzard Bag Filter RS filter, entry of contaminated air takes place through the space underneath the bag with shutter dampers.

The main advantage of a shutter damper is that when the air enters the filter, it “collides” with the shutter and disperses evenly along the filter elements, reducing the level of wear, as well as providing an even level of wear over the filter elements.

Installing shutter dampers provides a basis to save space in the dust extracting installation. Having a shutter damper in the baghouse provides a way to operate dust containing medium-sized and large particles which end up in the hopper right away after colliding with the shutter grid.

This is the cheapest version option in the Blizzard Bag Filter RS compared to the other ways of arranging contaminated air entry via damper plates or a side entrance.

The Dust Hopper and Unloading It

In the standard package, the Blizzard Bag Filter RS has a conical accumulation reservoir for dust and a round sealer with a hand lever for opening and closing or a box on wheels.

Additional hopper package

A vibrator or a vibrator installation to prevent dust from sticking to the hoppers walls.
Level transmitter
Hoppers and supports based on your enterprise’s order. For instance, we included a hopper that unloads into big bags for our wood-processing enterprise client.
The hopper with a worm under the bag for uninterrupted unloading of dust from the hopper with a flood hatch. In this case, the filter won't have to be stopped in order to unload the accumulated dust.

Unloading the Captured Product

Methods for the client to choose from for organizing unloading

The basic package involves the use of a manual method. A manual flow gate is used, and after it is manually opened, dust unloads out of a dust reservoir into a container or, other times, the container (box) the dust falls into can be connected to the filter without a flow gate.
The automated method: a flood gate or a double flap is used for unloading, often together with a worm transporter.

The main difference arises when it comes to manual labor needing to be exerted to unload the captured product. The automated method can be tied into a production chain and, for instance, the product can be returned back onto a conveyor belt.

Automatic “flood gate” (feed)

Mechanical “double flap”

Managing the Baghouse

Smart control automation guarantees uninterrupted operation

Control of the filter is performed using a controller or a remote-control device. This system operates in a closed cycle, but it can be reconfigured depending on the client's needs.

We propose packaging the filter along with a system entailing completely automatic control, analysis, and fire extinguishing. A time controller is installed in the standard package and a Siemens controller can also be part of the package, depending on your needs.

Pneumatic Cleaning System

Periodically filtered bags get covered with dirt, which increases the filter’s resistance. In order for the system to work in an uninterrupted fashion without any pressure differentials, the bags need to be cleaned. Cleaning is done in the following way:

On top, there are air pipes in the clean air chamber which start from the air system's diaphragm valves. These valves are installed for the receivers where the compressed air is kept, which is used for pulse jet.
The air is submitted from the compressor to these receivers. Periodically, the valve begins operation and the air is submitted to the air pipe via the valve and then out of the air pipe with the help of the nozzles and is distributed inside the filter bag.
The filtered bag is shaken and aired out while the dust falls down into the hopper accumulator from the filter bag.
The dust can be extracted from the hopper accumulator in three different ways, depending on the technical task envisaged: the manual dust latch, a mechanical “double flap”, and an automatic “flood hatch”. The standard version has a manual dust latch included.

Pulse Jet Cleaning System Package:

Compressed air receiver package
It is the receiver that accumulates air for the pulse jet. If there isn't enough air, the degree of cleaning will fall, the wear on the filters will increase, and the filter’s performance will fall, since the aerodynamic pressure of the filter will increase. The receiver has a flanged socket for connecting to the compressor or the general factory compressed air pathway, as well as a moisture drain valve. If “Blizzard” isn't installed in a heated facility, we recommend installing an oil and water separation, thermal, and air heating system.

Air pipe system
These are either metallic or plastic. Everything depends on the gas and temperature that the Blizzard bag filter RS filter is cleaning. Nozzles are installed on the air pipes for more efficient cleaning of the filter element.

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

Controller
Controlling the regeneration system is implemented with the help of a special controller that configures the impulse quantity and the frequency of them.

Differential manometer (by order)
Then bag cleaning can not only originate based on time but also in terms of the degree of the bags’ “contamination”. When the bags fall, the pressure in the filter changes and the manometer submits a signal to implement the draft. The differential manometer will also show an accident if one or more of the bags is ruined.
