Sleeve filters for aspiration. The filter is a sleeve with a pulsed purge and dust camera OHF-ST-C-FRI where the slength filter is usually applied

Perfectly working sleeve filters for aspiration - a universal type of equipment intended for cleansing airspace from dust, gas and other impurities. They can normally work in almost any technological processes, where dust and dirt is released. Such devices can function almost continuously, do not need permanent maintenance.

Sleeve filters for aspiration belong to the dusting devices of the so-called "dry" species. If compared with any categories of electrical filters and equipment for wet cleansing gases, then these filters have higher performance. The final dusting at the final stage after the functioning of these devices is no more than 10 milligrams per meter cubic. (There are also filters with even lower residual dusting - up to 1 milligram per meter cubic). In addition to the sleeve filters, the cleaning sleeves created from the filtering materials can actually be used at a temperature indicator, which constitutes up to +260 degrees Celsius.

Tasks that solve air aspiration

The required sanitary conditions are ensured to ensure that employees can be indoors without harm to their health.

Optimal conditions are created for all required technological processes.

The residues of dust, toxic and combustible compositions, explosive impurities, are eliminated from the air mass, which can be released at various production stages.

Aspiration air systems and self-purification filters are the designs of high ventilation equipment technologies. They are intended to absorb air where the chemical volatile gases are formed, dust, smoke, and so on. These systems make it possible to remove small particles of foreign origin from airspace, wood dust and chips, abrasive dust and avoid the spread of dust all over the room.

Sleep filters with pulse purge

The pulse sleeve filter is intended to purify air masses from various fine dust clusters. In these devices, an inserted system for the regeneration of impulse blowing with compressed air masses. Sleeves on metal supports protrude as a cleaning element. Can be used in industrial processes with a constant cycle, in particular:

manufacturing of building materials;

wood processing;

creation of mineral fertilizers;

foundry industry.

Everywhere it is useful for capturing fine dust.

Included with filters can go fan and air duct, dust collecting trolley and a gateway overloader, which makes it possible to carry out continuous caught dust clusters.

The pulse sleeve filter has the following principle of operation: the device catches the dust by filtering cloth when passing through it dusty air. While the density of the dust layer on the sleeveless surface increases, the ability of the device decreases. For this, the regeneration of contaminated sleeves with impulse blowing air was invented.

As for the control of the filter regeneration, the process of cleansing occurs automatically from the control shield. To optimize compressed air consumption, it is proposed to clean the pressure drop and continuous regeneration through certain time intervals.

Sleeve air filters

Sleeve filters are designed for industrial dusting and meet all modern characteristics and requirements: temperature regime, chemical medium, dust characteristics, service life, cleaning efficiency, etc.

Filtering materials for hose filters: polyester (polyester), polypropylene, polyacrylonitrile, meta-aramid (type "Nomex"), polyimide, fiberglass, etc.

Various regeneration methods: mechanical shaking, mechanical shaking in combination with a pulsed low pressure purge, low pressure pulse, impulse regeneration.

Manufacturing on the individual request of the customer.

Sleeve air filters for air purification from dust

To clear the dust-high compounds, you should use the hose filter. This device for the dust collecting "dry" species, which has a high degree of reliability and excellent processing quality. No appropriation, whether to wet cleaning or electrostatic filter, cannot be compared with the hose filter, because it is equipped with filtering devices, they can be used at high temperatures, because they are made of polyamide and polytetrafluoroethylene.

The slength filter is universal equipment, because it is essentially can be used in different technological processes. At the same time, it will be equally effective. You do not have to constantly monitor his work, because it functions continuously.

If you need a null filter of a certain size and with certain constructive features that approached your operating conditions, then you can order such a device, because such devices can be manufactured according to individual wishes. You, most importantly, you must specify which dust-forming composition is to be preferably cleaned. Manufacturers, pushing away from this, will pick you up the right material for the manufacture of the hose filter.

Where the sleeve filter is usually applied:

1. In the manufacture of building materials. 2. In the field of color and ferrous metallurgy. 3. In the process of foundry production. 4. In the process of automotive industry. 5. In energy and mining, furniture, glass and chemical industries. 6. In the production of food. 7. When processing metal.

Important Factors of Sleep Filter

In the process of selecting this filter, several basic moments must be taken into account, which include such items as:

· Temperature data of dew points with moisture degree; · Pressure, as well as temperature data; · Quality of gases, their explosion hazard and the volume of the medium that must be cleaned; · Dust density and its appearance; · How this stage occurs; · Toxicity of dust composition substances.

In order to calculate the sleeve filter, it is necessary to first install, in what amount the purge gas with dusty compositions are consumed, which fall on the material, and then take into account, at what speed, the fabric filtering process occurs, and it has been selected for the manufacture of the hose filter. How to exploit a slender filter?

The sleeve filter can be used:

1. In the fresh air, in an open place. In this case, the filter will require additional components of the elements:

· The hull part needs to be thermally insulated; · Preheating bunker elements; · Update systems; · Shelter that will prevent the impact of the atmosphere to the filter

2. In the closed room.

There are several varieties of sleeve filters:

· Dual-core with dirty and filtered gas pipes, located in the middle part of the device.

· Single-core with the same nozzles, but they are located in the side of the device. Sleeve filters for air filter from dust comes to the customer on the cargo transport in a partially disassembled type, although it depends on the complexity of the design. There is already welding of its composite elements on site. Some parts are attached to each other with bolts.

The sleeve filters with pulse purge are designed to clean air from dry finely dispersed unsalted dust in the central systems of aspiration. Can be used in industries with a continuous cycle, such as: production of building materials, mineral fertilizers, woodworking and foundry, etc.

Regeneration system - impulse blowing with compressed air. When the outdoor installation requires drying of compressed air to the dew point - 40ºС.

Sleep filter Found a wide application in food enterprises, tobacco factories, enterprises of metallurgical, petrochemical, mining, cement, flock, chemical and woodworking industries, ferroalloy factories, in the production of glass, plastic, carbon black.
Air purification filter is installed in aspiration systems, dust installations and other air purification systems for creating a clean atmosphere in various destinations. Designs and classifications sleeve filters diverse, but most often division sleeve filters It occurs in the form of filter hoses and according to the method of regeneration of the filter material.

Sleep filter consists of a core rectangular or round shape, bunker, filter sleeves (with a diameter of 100 to 300 mm), which are suspended inside the housing, special valves and regeneration control devices.
Polluted air passes through the fabric filter sleeves In the direction of the sleeve outside or vice versa inside.
Regeneration filter sleeves Performed after the limit accumulation of a certain amount of dust on the filter surface of the sleeve.
The sleeve filter is universal in that its configuration and overall dimensions can be different, taking into account the size of the workplace under the sleeve filter. Depending on the working environment, the life of the hose filter is from six months to several years.
Filter sleeves are the main element of the hose filter, most volatile and requiring replacement.
The filter sleeve material is selected depending on the operating conditions of the sleeve filter. In the manufacture of filter hoses, fabrics are used from natural fibers (cotton, wool), tissue from synthetic fibers, as well as fiberglass. The following materials were the greatest distribution: Oxalon, Nitron, Dakron, Terlin, Loven, Sulfon, Arselon, Polyimide, Orlon. The last four of these materials have a high heat resistance at 250-300 degrees.
For filter fabrics, the peculiar method of weave fibers is most characteristic. Nonwoven materials are also used - fetras manufactured by the method of sketching wool and synthetic fibers.
Appointment of filter sleeves: capturing various types of industrial suspensions (cement, plaster, carbon black, flour, etc.), air purification from dust and technological gases.

Filters sleeved with a pulsed purge and dust camera OHP-ST-C-FRI (Next installation) are designed for dry air purification from dust and aerosols.
Installations of OHP-ST-C-FRI belong to the settings of the middle class and can be used both as a small-time aspiration system for small shops and for cleaning air from fine dust formed during the operation of grinding equipment, re-edging building materials, plasma cutting, drills, shot blasting and sandblasting equipment.
