Bag dust collector is suitable for collecting small, dry and non -fibrous dust. After the dust -containing gas enters the bag dust collector, the dust of large particles and heavy particles will settle down under the action of gravity and fall into the ash bucket. When the gas containing relatively small dust passes the filter material, the dust will be stranded to purify the gas.

The bag dust collector is a dry dust removal device. After the filter material is used for a period of time, due to the sieve, collision, retention, diffusion, and electrostatic effects, such as a layer of dust accumulating filter bags, the dust of the dust is called the layer. During the exercise According to the role of the first layer, large net filtration materials can also obtain high filtration efficiency. With the accumulation of dust on the surface of the filter material, the efficiency and resistance of the dust collector increased accordingly. When the difference between the filter material on both sides is very large, some small dust particles attached to the filter material will be squeezed past, which reduces the efficiency of the dust collector. In addition, the high resistance of the dust collector will significantly reduce the airlift system. Therefore, after the dust collector's resistance reaches a certain value, it should be cleared in time. The gray score cannot destroy the initial layer to avoid reducing efficiency.

1. The working principle of the bag dust collector is: the dust -containing gas enters the filter room from the bottom of the flange at the bottom, the thick particles directly fall into the ash warehouse, the dust -containing gas is filtered through the filter bag, and the dust stays on the surface of the filter bag. Clean gas enters the clean air chamber through the bag mouth, and is discharged from the fan to the atmosphere. When the dust of the filter bag is increased, the program control instrument begins to work. Open the pulse valve in turn to spray the compressed air from the nozzle, clean the filter bag, so that the filter bag suddenly swells. Under the influence of reverse airflow, the dust on the surface of the cloth bag is quickly separated from the filter bag, fell into the ash warehouse, and was discharged from the ash valve.

2 Pulse dust collector's working principle: mainly consisting of the box, the middle box, the ash bucket, the import pressure balancer, the supporting filter bag, the jet device, and the gray removal device. Dust -containing gas enters the ash barrel from the entrance pressure balancer. Under the guidance of the ash fighting -oriented device, the large particles of dust are separated and fell directly into the gray bucket. The fine -grained dust is evenly entered into the middle box and adsorbed on the surface of the filter bag. Clean gas penetration filter bags enter the box. And discharge the atmosphere through the off -machine valve and exhaust pipe. With the improvement of the filtration conditions, there will be more and more dust on the filter bag. When the device's resistance value reaches the extreme resistance (generally set at 1500Pa), the dust removal control device will automatically close the off -room valve according to the pressure difference or dust removal time, and then press the setting value. Open the electrical control pulse valve regularly to prevent the air from spraying, instantaneous injection with compressed air, increase the pressure in the filter bag, the dust on the filter bag (even fine dust can be removed) and throw it to the gray fight, and fly through the exhaust emissions and fly through the exhaust emissions. mechanism.

3. The working principle of a whirlwind dust collector is that the dust -containing gas enters from the entrance. When the airflow performs rotation, the airflow is separated up and down to form a dual spiral motion. The dust has a strong separation effect at the dual spiral boundary, and the downward spiral air flows to the outer wall. Some dust are discharged through the hole in the middle of the bypass, and the remaining dust enters the ash through the down air. Spiral rising airflow can capture fine particles to improve dust removal efficiency. This small dust particles flow from the upper snail shell to the upper snail shell, forming a strong rotating upper dust ring on the upper cover. They entered the upper mouth of the bypass separation room with the upper snail airflow, and then entered the cone basin and the internal airflow through the return vent. The purified gas is discharged from the exhaust pipe, and the separated dust enters the fought.

4. The working principle of electrostatic dust collector: After entering the device from the top of the top, the dust -flying gases can rotate the screw along the axis at a high speed through the whirlwind separator, and use the centrifugal force to remove the dust particles. ; Effectively control the initial dust concentration into the electric field. Then the gas enters the electric field through the ash barrel. The low cross -sectional area ash bucket is several times that of the inner tire. According to the principle of constant torque, radial and axial wind speeds decreased sharply, resulting in the zero -speed interface, which caused the dust of the inner tire to fall into the ash. Fighting reduces the dust concentration of entering the electric field. Low -concentration dust -containing gas is condensed on the positive plate and negative plate through electric set dust. The collected dust is taken away by the ash and the gas lock is vibrated. In order to prevent the internal tube from being activated by the whose aircraft and electric field boards, the secondary dust formed in the lower ash bucket is specially provided with isolation cone. Scope of application: cement, fertilizer and other industries, various crushing machines, crushing points, packaging and dryers, and various similar dispersing sources.
