Performance characteristics of large long bag pulse bag dust collector: 1. Adopting pulse jet cleaning technology, the dust is cleaned and removed with low emission concentration, low air leakage rate, low energy consumption, low steel consumption, small footprint, stable operation, and good economic benefits. Suitable for flue gas dust removal in metallurgy, building materials, machinery, chemical, power, and light industry industries. 2. The box adopts an airtight design with good sealing performance. The inspection door uses excellent sealing materials, and during the manufacturing process, kerosene is used for leak detection, resulting in a very low air leakage rate. 3. The layout of the inlet and outlet air ducts is compact, with low airflow resistance. 4. The use of segmented air stop pulse spraying for dust cleaning has a long cleaning cycle and low consumption, which can double the lifespan of filter bags and valve plates. 5. It can achieve non-stop bag replacement and maintenance without affecting the normal operation of the equipment. 6. The operation of changing bags was carried out using the upper bag extraction method. The working mechanism of a bag filter is that the dusty flue gas passes through the filter material, and the dust particles are filtered out. The filter material mainly captures coarse dust by inertial collision, while capturing fine dust mainly relies on diffusion and screening. Working principle of large long bag pulse bag dust collector: The dust collector consists of ash hopper, upper box, middle box, lower box and other parts. The upper, middle and lower boxes are divided into compartments. During operation, dusty gas enters the ash hopper through the air inlet duct. Coarse dust particles directly fall into the bottom of the ash hopper, while fine dust particles enter the middle and lower boxes upwards with the turning of the airflow. Dust accumulates on the outer surface of the filter bag, and the filtered gas enters the upper box to the clean gas collection pipe exhaust duct, and is discharged to the atmosphere through the exhaust fan. The dust cleaning process involves first cutting off the clean air outlet duct of the room, so that the bag in the room is in a state of no airflow passing through (stopping the air and cleaning the dust in each room). Then, the pulse valve is opened and compressed air is used for pulse blowing to clean the dust. The shut-off valve is closed for a sufficient time for the dust peeled off from the filter bag to settle in the ash hopper after spraying, avoiding the phenomenon of dust adhering to the adjacent filter bag surface with the airflow after leaving the filter bag surface. The filter bag is cleaned, and the exhaust valve, pulse valve, and ash discharge valve are fully automatically controlled by a programmable controller. Design of Large Long Bag Pulse Bag Dust Collector Series: 1. The long bag pulse dust collector is divided into three different series according to the different diameters of the filter bags, the different arrangements of the filter bags in each chamber, and the different filtration areas. They are combined into rows based on the chamber, and are divided into single and double arrangements. a. Divided into single row and double row, the filter bag size is 130X6000. The pulse blowing pressure can be low pressure (0.2-0.3Mpa) or high pressure (0.4-0.5Mpa), which can be selected by the user. b. Only double row arrangement, with filter bag size of 130X6000. The pulse injection pressure is generally designed to be low pressure (0.2-0.3Mpa). c. Only double row arrangement, with filter bag size of 160X6000. The pulse injection pressure is high pressure (0.4-0.5Mpa). If requested by the user, the design can also be based on their feedback. 2. The dust concentration of the dust collector is generally allowed to be below 50g/Nm3. If required, it can be designed according to user requirements.
