Filter (Bag Dust), sometimes also known as filter bags, are made of fabric or membrane material and work as a filter chamber. In this process, the contaminated air passes through the filter bag and the dust and contamination particles are separated inside it. These filters are a popular solution to contamination due to the ability to separate particles as much micrometer and high performance in reducing air pollutants. This dust machine plays a very important role in various industries, including the drilling industry.
Buy Bag Filter (Bag Dust)
Bag Filter is one of the industrial equipment that is of great importance in the industry. It controls and manages dust particles in particular and collects contaminants in industrial and boiler environments. It controls sulfur dioxide and other dust particles that are seriously dangerous to staff and toxic. Industrial dusts play the role of air ventilation in industrial environments, especially the drilling industry.
Filter is made up of a compartment with filters inside the bag filters. If you want to know what this essential device is used in the drilling industry, we should say that this device is capable of removing solid particles in the air since 1970 after the fabrics and fibers were invented at 350 degrees. Differently became popular.
how does the dust filter work or the same filter?
Dust filter or Bag Filter is one of the types of air filters used to absorb and remove dust and other suspended particles in the air. These filters are used in air conditioning systems, factories, industries, cooling towers and other similar applications. The way this machine operates is that the dust carrier gas is entered into the filter and is returned to the fabrication of the material by bale. , Large diameter dust particles move to Hopper under their weight force. When the dust thickness on the bag reaches the extent that the current is barely passed, it is time to clean the bags. In fact, it is the task of the inlet section to reduce the speed of gas and gives the large particles the opportunity to fall to the sub -filter hops and gives the full gas distribution that carries the fine particles of dust between the bags.
Gas spreading causes the gas flow on the bags not to wear. The gas that contains dust goes around the bag and then enters the cleaning air compartment and then the suction fan sends it to the chimney.
This procedure is performed in succession to Where pulse air through the nozzles is periodically blown into the bags by an electric panel, and separates the material from the outer surface of the bags. The separated material enters the harper and is directed by the transition systems out of the filter.
When using the Filters' Bag in the dusting of gases resulting from the combustion and baking cliner, the issue to be taken into consideration The amount of filter bags is against high temperature gases. The use of Bag Filters makes the gases up to 10 mg / m3. Because they are both economically affordable and much more efficient. Fabric filters are mounted in rows vertically inside the metal chamber.
Filtering Mechanism in Bag Filter
Mechanical Sharing
In this way, by connecting one side of the cylindrical bag filter to a moving plate and then shaking that plate by an engine, shaking the filters The bag and the dust exit the bag filter. Due to the low ratio of pass -to -fabric for this type of box filters, a lot more of a bag is needed, which makes a lot of work space needed for this filter.
At the time The shaky performance of the system is out of line and their performance system is periodically. At the end, dust particles are transferred into the hops collected to the specified location.
Reverse air (Reverse Air)
This system is more common today for fiber dusts such as wood processing or cereal dust. The mechanism of this system is that the reverse air produced by the fan and the medium pressure blower is directed by the rotating arm on the bags and the reverse air is blown into them.
then dust from The bags are separated. Types of reverse air flow filters create less air than other methods, such as pulse jets. The advantage of this method is that this is a high -volume low -volume cleaner system that reduces abrasion and rupture of the bags.
pulse jet ( Pulse Jet
This system has the most efficiency compared to other types of filter cleansing systems that do not need to be removed from the line when operating. Today, Jet Plus filters are the most common type of Bag filter. The mechanism of pulse jets is such that the compressed air that compressors produce is blown into the bags by separate nozzles at the top of each bag.
with air explosion into the bags, round and round The dust is separated from the surface of the bag and finally the bag is cleaned. A guiding tube is located above each row of the bags, one end of which is closed and the other end is controlled by electric valves. When the pulse jet system is used, the valves open and the air inside the pipes is compressed.
use Venturi to guide air into the bags and with compressed air tail inside the bags , The dust on the surface of the filters is removed and pulled down and then collected by Hopper. The end of the Hopper is attached to a rotary valve and directs the collected particles out of the bag.
