Dust Extraction System:

In thermal power stations, Metal Furnaces , Coal/material Material conveying, Dust Generation is one of the most Nusiance .

Dust generation in a Material handling plant:

Loading point, Unloading point of belt conveyor, Discharge Chutes: Dust from the operation of belt conveyors originates mainly at the trail pulley where material is received and at the head pulley where material is discharged. Dust generation depends on belt width, speed, height of fall of coal.

Bunker Feeding Point: Crushed coal either directly from crushers or from the crushed coal stockyard is conveyed to boiler bunkers through traveling trippers or reversible shuttle conveyors. Dust is generated while loading the bunkers, spreading of which is controlled to some extent by conveyor sealing arrangement, and needs to be extracted from bunkers.

Crusher area: Crushers are used for size reduction in the coal or other particle. The huge gyratory or roller crushers are used for primary size reduction, while jaw or gyratory crushers are used for secondary size reduction. Large side hoods are used for dust extraction.

Dust Extraction Process:

The arrangement for dust extraction system for bunkers consists of eight Suction points, four on either side of Tripper Conveyor. The Tripper Conveyor feeds only two feeding points out of the eight, at a time. Thus for those two feed points, corresponding two suction hoods sucks dust laden gas in the system. While other six feeding points are closed using belt sealing arrangement. This dust laden gas is carried to the bag filer through interconnecting ducting.The gas is filtered through the bags due to the entrapment of dust particles into filter media. Each row of the bags, receives periodic pulses of compressed air, thus pulsing the bags, thereby dislodging the dust to the hopper. The pulsejet system is provided with a pressure switch to control the maximum pressure in the air header. The pressure drop across the bag house is measured by a Differential pressure Indicator or by a water tube manometer. In case of the excessive pressure drop, a Differential pressure switch comes into operation and provides a signal, which would be interlocked with Control Panel. The dislodged dust is collected in the hopper and discharged through the RAV. RAV is provided with zero speed switches to ensure overload protection of Geared motor. To improve the flow characteristics or to avoid chocking, rat holing, arching of dust in the hopper, Pneumatic knockers are provided on the hopper.

In order to control maximum level of dust in the hopper, a Level switch is provided. The level switch is to be interlocked with the control panel so that the dust level in the hopper should not rise above the set level. Coal dust is combustible and tends to form dust clouds, hence precautions for explosions is taken by providing explosion vent, to reduce the risks of property damage and personal injury. The Fan provided develops the necessary draft. The draft control of the Fan is carried by VFD. The VFD is provided with PID controller. The PID controller receives the signal from Differential pressure transmitter across the Flow measuring device, and gives controlling signal to VFD, to maintain necessary RPM of fan thereby maintaining necessary draft in the system. The clean air is discharged at the outlet of I.D. Fan.

    'Defective or mismanaged ventilation in chemical industries may expose workers to major health impacts like damage to the lungs, kidneys, liver and sensory organs, as well as death in extreme cases.

    So to avoid these adverse health effects of over-exposure to the harmful gases generated from Chemical industries, we recommend you to avail the Ventilation systems specially designed and manufactured by keeping OSHA Laws & Regulations in mind.'

    Industrial Ventilation systems:

    The importance of clean uncontaminated air in the industrial work environment is well known. Modern industry with its complexity of operations and processes uses an increasing number of chemical compounds and substances, many of which are highly toxic. The use of such materials may result in particulates, gases, vapors, and/or mists in the workroom air in concentrations which exceed safe levels. Heat stress can also result in unsafe or uncomfortable work environments. Effective, well designed ventilation offers a solution to these problems where protection is needed. Ventilation can also serve to control odor, moisture, and other undesirable environmental conditions. The systems are offered according to guidelines of OSHA and ACGIH norms that are worldwide accepted.

    Ventilation systems are of two generic types

    • The SUPPLY system is used to supply air, usually tempered, to a work space.
    • The EXHAUST system is used to remove the contaminants generated by an operation in order to maintain a healthful work environment.

    These systems are designed for chemical & pharma industries, fettling shops of foundry and others. Our team of experts makes sure to produce a range of products, which meets the OSHA requirements in an efficient manner.

    Exhaust Systems

    Exhaust ventilation systems are classified in two generic groups:

    • GENERAL exhaust system.
    • LOCAL exhaust system.

    The general exhaust system can be used for heat control and / or removal of contaminants generated in a space by flushing out a given space with large quantities of air.

    Local exhaust ventilation systems operate on the principle of capturing a contaminant at or near its source. It is the preferred method of control because it is more effective and the smaller exhaust flow rate results in lower heating costs compared to high flow rate general exhaust requirements. The present emphasis on air pollution control stresses the need for efficient air cleaning devices on industrial ventilation systems, and the smaller flow rates of the local exhaust system result in lower costs for air cleaning devices.

    Local exhaust systems are comprised of up to four basic elements:

    1. Hood(s),
    2. Duct system (including the exhaust stack and/or recirculation duct).
    3. Air cleaning / Conditioning device (Dryer / Humidifiers / Dehumidifiers / Filters etc).
    4. The fan.

    In many pharma industries accidents are caused by uncontrolled emissions of noxious chemicals that can compromise the safety of workers in workplaces and destroy costly business.

    And for all the above problems there's just one stop solution, Whizz Engineering Services Pvt. Ltd. We with our expertise provide you with exact solutions which are of superior quality and made to last long.

    Our objectives:

    • To ensure the health of workers.
    • To ascertain the safety of workers and business assets.
    • To guarantee the efficiency and effectiveness of equipment and operational processes.
    • To help bring about a cleaner and safer global environment.

    Benefits of our Exhaust ventilation systems:

    • Better control on chemical vapours
    • Better ergonomics
    • More efficient use of available local exhaust ventilation
