Dust Collector System

The main structure of the high-efficiency pulse dust collector consists of several parts, including the upper box body, the middle box body, the ash hopper, the ash unloading system, the spraying system, and the control system. And equipped with basic pillars, ladders, railings, and access doors. Adopting a lower intake structure, the dust containing flue gas enters the ash hopper through the lower part of the middle box through the air inlet. Some larger dust particles directly fall into the ash hopper due to inertial collision, natural sedimentation, and other effects. Other dust particles are filtered by the filter bag as the air flow rises, and are blocked and left on the outside of the filter bag. The purified gas enters the upper box from the inside of the filter bag, and is then discharged into the atmosphere through the air duct and fan through the air outlet. The dust in the ash hopper is regularly or continuously discharged by the unloader.

Adopting a lower intake structure, the dust containing flue gas enters the ash hopper through the lower part of the middle box through the air inlet.

The purified gas enters the upper box from the inside of the filter bag, and is then discharged into the atmosphere through the air duct and fan through the air outlet. The dust in the ash hopper is regularly or continuously discharged by the unloader. As the filtration process continues, the dust accumulated on the outside of the filter bag continues to increase, resulting in an increase in the resistance of the bag room dust collector itself. When the resistance reaches the predetermined value (which can be determined during equipment debugging), the ash cleaning controller sends a signal, and then opens the electromagnetic pulse valve to inject 0.4-0.5Mpa compressed air into the box in a very short time. Compressed air is sequentially sprayed into the filter bag by the air source through the air bag, pulse valve, nozzle on the blowing pipe, and for an extremely short time (0.1-0.2S). Compressed air expands at high speed inside the box, causing high-frequency vibration and deformation of the filter bag. In addition, the effect of reverse airflow causes the dust on the outside of the filter bag to fall off. After ensuring that the dust falls off, open the next electromagnetic pulse valve for such a cycle. During ash cleaning, each solenoid valve is operated in a pre-set sequence without interfering with each other, achieving long-term continuous operation. For industries and mines with uncertain dust content, dust collectors can be used to achieve dust removal through resistance.

  • lead acid battery manufacturing machinery metal & metallurgy machinery line production dust collector Bag dust collector The working principle of a pulse bag dust collector is to enter the dust containing gas into the ash hopper through the air inlet or into the filter bag room through an open flange. The dust containing gas passes through the filter bag as clean gas and enters the clean gas room. It then passes through the exhaust port of the clean gas room and is discharged by the fan. Dust accumulates on the outer surface of the filter bag and continues to increase, causing the resistance of the pulse bag dust collector to continuously increase. In order to ensure that the equipment resistance does not exceed 1200pa and the pulse bag dust collector can continue to work, it is necessary to regularly remove the dust on the filter bag. Ash cleaning is a process in which a pulse valve is activated in a timed sequence controlled by a program, causing compressed air inside the air bag to be sprayed out through the orifice of the blowing tube and induced by a venturi tube to enter the filter bag, causing it to rapidly expand in an instant. With the reverse effect of the airflow, the dust is shaken off to achieve the purpose of ash cleaning. When the dust containing gas passes through the filter cloth in the process of bag filter, the gaps between the filter cloth fibers or the gaps between the dust adsorbed on the surface of the filter cloth separate the dust larger than the diameter of the gaps, which is called screening effect. For the new filter cloth, due to the large gap between the fibers, this effect is not significant and the dust removal efficiency is also low. The screening effect is only significant when a certain thickness of dust layer is established on the surface of the filter bag after a certain period of use. After dust removal, due to a certain amount of dust remaining on the surface and inside of the filter bag, good dust removal efficiency can still be maintained. For needle punched felt or fluffy filter cloth, as the felt or fluffy filter cloth itself forms a thick porous filter layer, it can fully exert the screening effect and does not rely solely on the dust layer to maintain high dust removal efficiency. The filter bag uses compressed air for blowing and cleaning, and the cleaning mechanism consists of an air bag, a blowing pipe, and an electromagnetic pulse control valve. The top of each row of filter bag outlets in the filtering room is equipped with a spray pipe, and the lower side of the spray pipe is directly facing the center of the filter bag with a spray port. Each spray pipe is equipped with a pulse valve and is connected to the compressed air bag. When cleaning, the electromagnetic valve opens the pulse valve, and compressed air is sprayed into the filter bag through the nozzle. Together with the surrounding gas it injects, it enters the inside of the filter bag, causing it to shake completely and forming a reverse blowing airflow from the inside out, removing dust attached to the outer surface of the filter bag and achieving the purpose of cleaning. Pulse jet cleaning: This cleaning method has the highest cleaning kinetic energy applied to the dust layer and is a typical method of external filtration for cleaning. The fine dust force is very strong, and the residual amount of dust adhering to the yarn inside the dust removal bag is relatively small. The dust removal bag used is usually felt or needle punched felt. Under the action of pulse blowing, the dust removal filter bag undergoes significant instantaneous deformation and generates significant stress, so it is necessary to use filter materials with strong tensile resistance. Dust removal bags often rub against the skeleton, so wear-resistant dust removal filter bags should be used, and fabric dust removal bags can also be used.

  • equipment metal refining for mine and metallurgy desulfurization tank for air clear system line Desulfurization technology The flue gas desulfurization technology, also known as the dual alkali flue gas desulfurization technology, was developed to overcome the disadvantage of easy scaling in the limestone lime method. There are dozens of types, and according to whether water is added during the desulfurization process and the dry and wet forms of desulfurization products, flue gas desulfurization can be divided into three major categories: wet, semi dry, and dry desulfurization processes. Wet desulfurization technology is relatively mature, efficient, and easy to operate. The traditional limestone/lime gypsum flue gas desulfurization process uses calcium based desulfurizers to absorb sulfur dioxide and generate calcium sulfite and calcium sulfate. Due to their low solubility, scaling and blockage phenomena are easily formed in the desulfurization tower and pipeline.
