Introduction of bag filter device
Bag filter device is a commonly used solid-liquid or gas-solid separation equipment, widely used in chemical, pharmaceutical, food and beverage, environmental protection, water treatment, metallurgy, oil, natural gas and other industries. Its working principle is mainly through the filter bag (filter bag) to capture the solid particles, suspended solids, some colloids and other impurities in the fluid (can be liquid or gas), so as to achieve the purpose of purifying the fluid.
Two, bag filter device composition
Stainless steel bag filter device is an efficient liquid filter equipment, widely used in chemical, petroleum, pharmaceutical, food, water treatment and other industries. It mainly consists of the following parts:
1. Shell: made of high-quality stainless steel material, with good corrosion resistance and pressure resistance, to ensure the stable operation of the filter device under various working conditions.
2. Filter cartridge: used to fix the filter bag and connect with the shell to support and protect the filter bag.
3. Filter bag: is the core part of the filter device, made of special filter materials, with high filtration accuracy and high throughput. The material and specifications of the filter bag are selected according to the actual application requirements.
4. Sealing ring: used to ensure the sealing performance of the filter device and prevent liquid leakage.
In addition, according to the size of the filter bag, the stainless steel bag filter device can be divided into 1, 2, 3 and 4 bag filters. According to the number of bags contained in the filter can be divided into single bag, double bag and multi-bag. In the direction of liquid inlet and outlet, it is divided into side-in bottom-out type and bottom-in bottom-out type. Filter material is high quality stainless steel, such as 304, 316, 316L and so on.
Third, the applicable industry of bag filter device
With its wide applicability and efficient filtration performance, the bag filter device has its figure in almost all industrial fields and water treatment industries, especially in the need for efficient purification and separation, is an important tool to achieve environmental protection and production process optimization.
Technical principle of
When the bag filter filters the liquid, the liquid enters from the side of the filter container or the liquid inlet below, and is flushed into the filter bag by the filter bag supported by the net basket. The filter bag is evenly distributed on the inner surface of the whole filter bag due to the impact of the liquid and the uniform pressure surface. The liquid through the filter bag is discharged from the bottom outlet of the filter along the wall of the metal supporting mesh basket. The filtered particles are trapped in the filter bag to complete the filtration process.
In order to maintain the high efficiency and filtration accuracy of the filter and ensure that the downstream liquid is not polluted, the machine should be shut down after running for a period of time, open the end cover of the filter, remove the interceptions and filter bags together, replace the new filter bag, the replacement cycle depends on the actual situation.

Frequently Asked Questions
Q: Bag filter bag clogged frequently how to do?
A: Check and replace the filter bags regularly, while ensuring that the pre-filtration system works effectively to reduce the amount of particulate matter entering the bag filter. You can also increase the backblow or cleaning frequency to reduce clogging.
Q: How to deal with bag filter leakage?
A: Stop the machine immediately to check and replace the damaged filter bag or seal. Verify that the design pressure is not exceeded and check for improperly installed or damaged pipe connections.
Q: How to deal with excessive pressure difference of bag filter?
A: The pressure difference is too large usually means that the filter bag is too dirty and needs to be cleaned or replaced. First perform the backblow cleaning operation, if the pressure difference is still too high, you need to replace the filter bag.
Q: How to improve the efficiency of bag filter?
A: Select a filter bag with the right micron grade to accommodate the particle size to be filtered, maintain the appropriate airflow speed, and ensure that the filter is properly installed and maintained.
Q: What causes excessive noise when the bag filter is working?
A: The noise may be caused by high-speed particles in the air stream impacting the filter bag, or the structural components of the equipment are loose. Check and tighten all structural components and ensure that the filter is operating at normal airflow speeds.
