Four types of dust removal methods for bag dust collectors:
(1) Progressive air type and downdraft air type means that the dust-containing air inlet is located at the upper part of the baghouse of the bag filter, and the airflow and particulate dust settle in the same direction. Downwind type is the dust-containing air inlet located at the lower part of the bag room. The airflow and particle dust settle in the opposite direction. If the outside looks downwind, but there is a deflector inside the bag room to divert the dust air into the upper part of the bag room, it should be classified as a progressive air type.
(2) Round filter type and flat filter type means that the dust-removing cloth bag is cylindrical. Flat filter means that the filter bag is flat (envelope-shaped) trapezoidal, wedge-shaped and other non-cylindrical.
(3) Suction and press-in suction means that after the fan is located in the bag filter, the bag filter operates under negative pressure. Press-in means that before the fan is located in the bag filter, the bag filter operates under positive pressure.
Four types of dust removal methods for bag dust collectors (4) Internal filter type and external filter type Internal filter type refers to the flow of dust-containing air from the inside of the bag to the outside of the bag, and the dust is trapped in the dust bag. External filtration refers to the flow of dust-containing air from the outside of the bag to the inside of the bag. The dust is collected outside the bag. The outer filter round dust bag is usually sewn with flat filter material or hot-melt bonded. The diameter of the round bag can be φ80 ~ φ200 mm, the most commonly used is φ115 ~ φ160 mm, the length of the bag is generally 2 ~ 6m, and the maximum length is 8m. The outer filter bag should be provided with a structure that supports the filter bag when it is used, so that the filter bag can maintain normal working condition under pressure. The size of the outer filter round bag and the structure are related to the dust removal function and service life of the filter bag. Synthetic fiber outer filter round The bag and the structural dimensions should be loosely matched, that is, the diameter and length of the outer filter round bag should be slightly larger than the matching structure size. For example, the outer filter round bag of φ120 mm should be equipped with a structure of φ115 mm, and its length should be 15 times longer than the structure. ~ 30 mm, so that the filter bag will have a certain width when removing dust. The glass fiber outer filter round bag should closely match the structure size. For example, the outer filter round bag of φ120 mm should adopt the structure of φ120 mm, and the length is the same. In this way, when removing dust and blowing air, the amplitude of the filter bag is small to prevent frequent dusting and twisting of the bag.
The operating principle of the bag filter:
The dust-laden gas enters the cabinet from the open air inlet at the bottom. The relatively large particles of dust fall directly into the ash hopper. The dust-laden air is isolated by the filter bag, and the dust is isolated and stayed outside the cloth bag. The clean gas Pass the bag opening to the clean room, and finally discharge from the fan. The dust on the outside of the filter bag is continuously thickened, and the pulse device starts to work. The pulse valve is opened one by one, and compressed air is blown through the nozzle to clean the filter bag, so that the filter bag expands. The outside dust falls out of the filter bag and falls into the ash hopper. The dust is finally discharged by the ash discharge valve.
