The pulse bag filter in a cement plant is a combined solid gas separation device that combines cyclone separation and bag filtration. It integrates centrifugal separation and mechanical filtration based on the characteristics of various types of crushed materials in wood processing and artificial board enterprises, and combines the advantages of two types of separation performance. It belongs to the current domestic dust removal equipment.

1. Technical characteristics of dust collector:

1. Able to handle high concentration mixed airflow.

Compared with conventional secondary dust removal systems, it has a reasonable structure, small footprint, reduced total system resistance, low energy consumption, and low investment

The cleaning method and economical cleaning parameters of 3 fully reflect the optimized design of dust collectors and energy conservation

4. Filter bags specially selected based on the characteristics of dust.

5. There are no moving parts inside the dust collector, making maintenance convenient.

2. Dust collector structure

The cyclone pulse bag filter is a cylindrical pulse bag filter with a length of outer cylinder set at the lower section of the cylinder, so that the inner and outer cylinder sections form a relatively independent and sealed cavity, and a tangential air inlet is set on the outer cylinder.

3. Working principle

The dusty gas entering the dust collector rotates between the inner and outer cylinders, and the airflow changes from linear motion to circular motion, moving downwards along the cone to form an external rotating airflow. The dusty gas generates centrifugal force during rotation, which throws the dust particles in the gas towards the gas wall; Once dust particles come into contact with the gas wall, they lose their chronic force and fall along the wall under the downward force of gravity, entering the ash discharge outlet. The external swirling airflow forms an upward internal swirling airflow in the cone section, moving in a spiral shape upwards and being discharged through the air outlet. Its function is equivalent to that of a regular cyclone dust collector. The bottom of the inner cylinder is the air inlet of the bag filter, and the rotating airflow is conducive to uniform air intake; The blocking effect of the inner cylinder avoids the direct impact and damage of high-speed airflow on the filter bag, extending the service life of the filter bag. The cleaning process of the cyclone pulse bag filter belongs to online cleaning, and the dust sucked down from the filter bag and the dust separated by the cyclone fall into the ash hopper together.

4. The inlet of the CFMC cyclone bag type cyclone dust collector is located in the upper section of the dust collector, which has the advantage of allowing the dust collected by the filter bag to directly fall into the ash hopper, avoiding mixing with the rising airflow of the cyclone. So it is suitable for purification applications such as food, beverage, and wood processing. The specifications and performance of the woodworking pulse bag filter are as follows: ① Three specifications of filter bag length: 3m, 4m, 5m; ② Filter area 66~304m2; ③ Processing air volume of 5000~50000 m3/h; ④ High operating temperature of 130 ℃; ⑤ Large negative pressure 5Kpa;
