What is the pulse blowing of bag filter? The dust removal method of bag dust collectors is from our oldest manual dust removal, to mechanical vibration, to pulse blowing. The efficiency is getting higher and higher, and the greatness of human wisdom is once again proven, although pulse blowing It is applied in the market, but many people still do n’t know what is the pulse injection of bag dust collector. Here we come to see what is the pulse injection of bag dust collector?
The bag sprayer's pulse blowing seems to be a simple device. It is an air-blowing device, but he can be no less careful than the bag. First of all, we must choose the appropriate size and number of pulse valve and design a dust collector. Need to choose a few inches of pulse valve and the number of pulse valve distribution according to the arrangement of filter material and the length of filter material. If this selection is not good, it will cause the dust collector to have very poor dust removal effect, and the resistance will increase, blocking the filter material.
Next, we need to choose a suitable injection position and air bag. Under normal circumstances, the height of the injection port should be more than 100 mm in the filter material, because the first stage of compressed air is easy to damage the filter material. It is also an important accessory. The air bag is too small, which causes the pressure not to go up, and the air supply is insufficient. The chain will fall off when dealing with longer bags and larger dust collectors. Then we talk about control. One of the more ancient methods is time control. Set the time on the pulse controller and spray it frequently. However, this control method has no other points than cost savings. It is even very gas consuming. Nowadays, high-end equipment will be equipped with a differential pressure controller, which will automatically sense the resistance of the filter through a module. When the resistance is higher than one, Value will continue to blow until the pressure is below a certain minimum. And it will have both time control and differential pressure control.
pulse Working principle of bag filter :
★. Under the action of the induced draft fan, the dust-containing gas enters the filter room from the ash bucket (or the open flange at the lower part), and a part of the larger dust particles directly falls into the ash bucket or ash bin.
★ 、 The remaining dust-containing gas is filtered by the filter bag, then passed through the mouth of the bag to the clean room, and finally discharged into the atmosphere by the fan, while the dust adheres to the outer surface of the filter bag;
★ 、 As the dust on the surface of the filter bag increases continuously, the resistance of the equipment also increases. When the set value is reached, the time relay (or differential pressure controller) outputs a signal.
★, the program controller starts to work, turn on each pulse valve in turn, and let the compressed air through the nozzle to blow the dust out of the filter bag,
★, The filter bag suddenly expands under the action of high-pressure air, and the dust attached to the bag surface is quickly separated from the filter bag and falls into the ash hopper (or ash bin) under the action of reverse airflow. The dust is finally discharged by the flap valve.
★, the spray only cleans the filter bags one by one, and the other filter bags still filter normally, which does not affect the dust removal of the whole machine.
