MAIN OBJECTIVES OF AIR CLEANING EQUIPMENT:

1. Delay (capture) of pollutants.

For that filter elements are responsible. They come in various shapes, types and sizes.

In dry types of filtration, the most common are bag and cartridge filters, as well as absorbents.

In wet forms - water or other liquid with various reagents.

In addition to the types of filter elements themselves, the size of the filter element, its shape and location inside the equipment are important. For example, one can very close filter elements and then the installation will become clogged with dust faster and require more frequent maintenance and replacement of filters.

It is possible vice versa arrange the filters at a distance from each other, thereby increasing the housing and solving the problem of frequent clogging of filters. The choice of the arrangement of the filter elements depends on the nature of the dust.

2. Collection of pollutants.

Together with the removed air, a large number of various inclusions pass through the air ducts, which, after being captured, must be collected.

The dust collector is responsible for this. They come in various designs - a conical hopper, an elongated hopper with an auger, a dust box, a big bag, a bag and other drives.

In order for most of the pollutants to immediately enter the dust collector, various methods of removal (separation) of pollutants are used, such as: the entry of pollution through the side gas inlet, the entry of pollution through the dust chamber with an absorber plate, or the entry of pollution into the underarm space.

These methods are used to direct most of the contaminant directly into the dust collector and facilitate the work of the filter elements.

3. Unloading pollutants.

Unloading is divided into manual method and automated.
Manual - when a manual damper is used, by opening it manually, the dust is unloaded from the dust collector into some kind of container or when a container (box) into which dust falls is immediately connected to the filter without a damper.
Automated - when a sluice or double flasher is used for unloading, often together with a screw conveyor.

The difference between manual and automated is in manual labor, which must be applied to unload the caught product. An automated method can be linked to the production chain and, for example, return the product back to the conveyor.

The choice of one or another method of unloading also depends on the amount of the captured product, if the concentration is high, then continuous unloading is required, and vice versa, if the concentration is low, then unloading can be done manually and periodically.

WHAT DATA IS NECESSARY FOR THE CORRECTSELECTION OF FILTERING EQUIPMENT:

for drawing up a preliminary design and estimates.

In many industries, a certain amount of harmful substances is released into the air in the form of small particles of suspension, dust and other elements that have a negative impact on both the production itself and the health of service personnel.

Personal protection systems for personnel (respirators, masks, gas masks, etc.) in these cases are ineffective, as they quickly become contaminated and require frequent replacement.

The most efficient way air pollution control in industrial areas are air aspiration systems.

Aspiration is the process of removing dust (gas) generated during the operation of equipment from industrial premises.

Air aspiration systems are one of the types of ventilation systems. The principle of operation of both systems is the same - the movement of air through the ducts with the help of fans, draft machines, etc. The difference between the systems is in their functional purpose:

1. Ventilation is designed to control the air quality in the entire room (workshop).

2. Air aspiration systems are used to remove contaminants from the working area of process equipment.

That is, the air flow is used to move fine particles and harmful substances from the working area to the disposal or cleaning area.

Air aspiration systems or machine tools should not be confused with pneumatic transport systems. Pneumatic transport - this is the movement of particles by air flow to perform the technological process.

Air purification by aspiration systems is necessary where, during the production process, substances harmful to breathing are released and compliance with sanitary standards or process requirements is required.

Suction systems Widely used in many industries :

Agriculture
textile industry
mining industry
woodworking
food industry
metalworking

The principle of operation of the air aspiration system is as follows:

in the area of the pollution source using a centrifugal fan (dust, draft, high pressure fans) reduced pressure is created. Polluted air is captured by an air inlet (funnel, umbrella, grate, etc.) and sucked into the air duct of the aspiration system. Further, it is fed through air ducts to a cleaning device (cyclones, filters, cartridge filters, silos, etc.). There there is a separation of polluting elements (fine chips, dust, etc.) from the air. Then the purified air returns to the room or is released into the atmosphere, and dust and chips are deposited in a special bunker.

Features of designing aspiration systems.

Aspiration systems are designed and installed according to completely different principles than simpler ventilation systems.

Here are just some of the features of their device, which ensure the efficiency of work, the absence of blockages, breakthroughs, sticking and eliminate the early wear of air ducts:

air velocities in the ducts must be significant, preventing dust settling on the walls and contributing to their self-cleaning;
for the same purpose, air ducts are installed in an inclined position, at an angle of 55-60 °;
be sure to use thick-walled steel ducts;
installation of aspiration systems is carried out using more durable fixtures - special brackets or chains;
to connect air ducts, quick-dismountable structures are often used - flanges and special adjusting devices - dampers.

1. The nature of the polluting particles

It is necessary to know the composition of the exhausted dirty air. Since air pollutants can be different, then and they are captured in various ways: dry, wet, combined, including multi-stage. Possible types of installations: cyclones, bag filters, various scrubbers, gas converters and others.

2. Sizes of removed particles

Solid dust particles come in different sizes: from 0.1 to 100 microns From the size of the removed particles depends on the type of filter material, its composition, as well as equipment size.

3. Concentration of pollutants

How many grams or milligrams of pollution is in one cubic meter of air. This parameter will determine what type of equipment is economically feasible, and what kind of filter material and filter element will be used in the treatment plant.
