Bag dust removal equipment What is back blow dust removal?


What is bag dust removal equipment and what is back blow dust removal? Back blowing dust removal is a method of removing dust by deforming the filter bag with the airflow opposite to the airflow filtering, and removing the dust layer.


There are two mechanisms of back blowing dust removal: ① The air blow of the back blowing dust directly impacts the dust falling off; ② As the direction of the air flow changes, the filter bag will expand and shrink, causing the dust to fall off. Therefore, the speed of the back blowing air flow is also an important factor affecting the dust removal effect.


To set up a separate fan supply. According to the pressure of the dust cleaning air flow in the filter bag, it can be divided into positive pressure backflush and negative pressure backflush.


The invention has the advantages that the air flow is distributed uniformly on the entire filter bag, the vibration is not serious, and the damage to the filter bag is small. Its disadvantages are the same as mechanical vibration dust removal. It is necessary to stop filtering and dust removal. It can also be solved by grouping the filter bags into groups and removing dust one by one.


The dust removal mechanism of the anti-blow bag dust removal equipment can be divided into "two-state dust removal" and "three-state dust removal"


During the normal operation of the anti-blow bag dust removal equipment, the dust-containing gas passes through the filter from the inside to the outside.


The bag swells the filter bag. When cleaning dust, close the clean air outlet of the room and open the reverse blow port to make the inside of the filter bag in a negative pressure state. The outside air or circulating flue gas is sucked into the inside of the filter bag from the outside of the filter bag as a back blow gas to shrink the filter bag. And shake off the dust deposited inside the filter bag.


With this kind of ash cleaning mechanism, the filter bag is in two states of "swell-back suction", so it is called "two states" ash cleaning method. At present, most domestic anti-blow bag dust removal equipment adopts this method.

Bag dust removal equipment What is back blow dust removal? What is pulse jet dust removal?


Pulse spray cleaning is performed in a very short time (not more than 0.24 into the filter bag at high speed, and induces several times more air than the injected air to form an air wave, so that the filter bag is generated from the bag mouth to the bottom Rapid expansion and shock vibration cause dust accumulation and drop.


When blowing, the filter bag after dust removal has no dust suction effect. Due to the short blowing time, the filter bag blows dust one by one, which can almost be said to be a continuous dust collection operation.


Pulse jet dust removal is strong, the dust removal effect is good, and the filtering wind speed can be improved. The dust removal effect is related to the atmospheric pressure, the structure of the dust removal equipment, whether the jet centerline is consistent with the filter bag centerline. In cold areas, the condensation of water vapor in compressed air will affect the blowing effect and is not suitable for outdoor use.
