Bag filter application

Structure and working principle: The bag filter is a multi-purpose filter device with novel structure, small size, simple and flexible operation, energy saving, high efficiency, closed working and strong applicability. The bag filter is a pressure type filter device, which mainly comprises a filter cylinder, a filter cylinder cover and a quick opening mechanism, a stainless steel filter bag reinforcing net and the like, and the filtrate flows into the filter bag from the side inlet pipe of the filter casing. The filter bag itself is installed in the reinforced basket, and the liquid is permeated through the filter bag of the required fineness level to obtain a qualified filtrate, and the impurity particles are intercepted by the filter bag. The machine is very convenient to replace the filter bag, and the filter is basically free of material consumption.

The main advantages of the bag filter:

1. The filter bag side leakage rate is small, which effectively guarantees the filtration quality.

2. Bag filter can carry greater working pressure, low pressure loss, low operating cost and obvious energy saving effect.

3, filter bag filtration accuracy has been continuously improved, has reached 0.5μm.

4. The bag type filter has large processing capacity, small volume and large volume of dirt.

5. Based on the working principle and structure of the bag filter system, it is convenient and quick to replace the filter bag, and the filter is no-clean, saving labor and time.

6. The filter bag can be used repeatedly after cleaning to save costs.

7. Bag filter has a wide range of applications, flexible use and various installation methods.

Bag filter specifications:

Bag filters are divided into: single bag filters, multi bag filters and sandwich filters. Multi-bag filter for high flow filtration. From 2 bags to 24 bags, the specifications are complete, the diameter of the inlet and outlet flanges is φ50-450MM, and the maximum flow rate of single machine is 90-1000m3/h. Quick opening design is available, and filter bag replacement is very convenient. It is also suitable for occasions where it is desirable to apply a longer period of time before replacing the filter bag. The multi-bag filter has a large volume and a heavy top cover, which is difficult for a worker to operate. The filter is equipped with a rocker arm device to reduce labor costs and meet customer requirements.

Filtration operation and precautions:

The bag filter is easy to operate. When it is used, it is only necessary to install the filter bag of the required fineness level in the filter cartridge, check whether the O-ring is in good condition, and then tighten the filter cartridge cover ring bolt to be put into operation. After the pump is started, the pressure gauge on the filter rises slightly, and the initial pressure is about 0.05MPa. With the extension of the use time, the filter residue in the cylinder gradually increases. When the pressure reaches 0.4MPa, the cylinder cover should be stopped and the filter bag should be checked. In the case, the replaceable filter bag can continue to be used (the filter bag is generally reusable by cleaning). The pressure of the filter is generally adjusted to 0.1-0.3 MPa, which can be adjusted by the return line or the return valve on the pump. If the filter pressure is too high, the filter bag and the protection net will be damaged, so pay special attention.
