Pulse Bag Filter

The pulse bag filter is a dry filter device. It is suitable for capturing fine, dry, non-fibrous dust.
The filter bag is made of woven filter cloth or non-woven felt, and the dust-containing gas is filtered by the filtering effect of the fiber fabric.
When the dust-containing gas enters the bag filter, the dust with large particles and heavy specificity will be affected by gravity. The effect settles down and falls into the ash hopper.
When the gas containing finer dust passes through the filter material, the dust is blocked, so that the gas is purified.

DMC pulse bag fiter, designed by us on the basis of absorbing many advantages of the same products, adopts advanced pulse blow technology.
DMC pulse bag fiter enables the machine completely clear the dust, low resistance. The qualified spare parts ensure the high-efficiency of bag filter.
It also have advantages of full automation, high-efficiency, easy maintenance.
It is not only suitable for collection of various powders, also can be used for dust purification of various crushing and screening equipment.

Features

●High-fficiency. This pulse bag flter can be used to purity dusty gas with particle diameter more than 0.1μm.
●Collection efficiency can reach more than 99.5% in general, stable and reliable performance, easy operation.
●Strong adaptability. This pulse bag flter can capture various properties dust, and the collection fficiency isn't affected by dust or resistance properties.

Working Principle

Pulse bag filter mainly consists of upper box, middle box, lower box (hopper), dust cleaning system and discharging system.
After the dusty gas gets into the upper box, the flow surface broaden suddenly, part of coarse particles fall down into the hopper by gravity, air flow distribution and inertial force.
Fine and low-density dust enter dust chamber and cling to the surface of the filter bags.
At the same time, PLC controls the startup of pulse valve, compressed air flock into filter bags, which makes filter bags expanded and vibrated, and then the fine powders cling to the surface of flter bags fall down into hopper and discharged on the discharge valve.
At last, filtered clean air will be emitted from exhaust pipe.

Pulse bag filter maintenance

1. Frequently check the operation of control valve, pulse valve and timer.

The failure of rubber diaphragm of pulse valve is a common fault of bag filter, which directly affects the ash cleaning effect. The equipment belongs to the external filter type, and the bag is equipped with a skeleton. Check whether the parts fixing the filter bag are loose and whether the tension of the filter bag is appropriate. Whether the support frame is smooth to prevent abrasion of the filter bag. Compressed air is used for ash cleaning. Therefore, it is required to remove oil mist and water droplets, and the oil-water separator must be cleaned frequently to prevent movement mechanism failure and filter bag blockage.

2. Whether the treatment air volume and the pressure and temperature at each test point are consistent with the design.

3. For the installation of filter bag, whether there is bag falling, loosening and wear after use can be judged by visual inspection of the discharge of chimney after operation.

4. Prevent condensation

During use, prevent the gas from cooling below the dew point in the bag room, especially when using the bag filter under negative pressure. Because air often leaks into its shell, so that the gas temperature in the bag chamber is lower than the dew point, the filter bag will be damp, so that the dust is not loose, but sticky attached to the filter bag, blocking the fabric holes, resulting in ash removal failure, resulting in excessive pressure drop of the dust collector, unable to continue to operate, and some paste bags can not remove dust.

To prevent condensation, the temperature of the gas in the dust collector and its system must be kept 25 ~ 35 ℃ higher than its dew point (e.g. the dew point temperature of the kiln mill integrated machine is 58 ℃, and the operating temperature should be more than 90 ℃), so as to ensure the good use effect of the filter bag.
