The construction of a pulse bag filter mainly consists of a fan, a box, an ash discharge device, a control system, etc. It is determined based on factors such as the properties of smoke or dust, application scenarios, dust particle size, viscosity, gas temperature, moisture content, dust concentration, and different filter media. The pulse bag filter is all placed in a circular steel plate welded box, which has a convenient structure and operation. The lower part of the pulse bag filter unit is directly connected to the dust removal equipment such as the warehouse top, material bin, and belt transportation with flanges for on-site dust removal, and the dust is directly recovered. Reforming the structure and pulse valve has solved the problems of outdoor placement and low compressed air pressure.
According to different diameters of filter bags, different arrangements of filter bags in each chamber, and different filtration areas, pulse bag dust collectors can be divided into three different series. They are combined into rows based on the chamber, divided into single and double arrangements. The dust concentration of pulse bag dust collectors is generally allowed to be below 50g/Nm3. If required, they can be designed according to user requirements. It has two types of dust cleaning functions: timed and pressure differential, as well as various automatic controls. Generally, under stable working conditions, timed dust cleaning can be set. For different smoke and dust working conditions and dust removal system requirements, constant pressure differential dust cleaning can be set to ensure stable operation of the dust collector.
The pulse bag filter is a breakthrough in bag filtration efficiency, achieving continuous operation. It has the characteristics of simple operation, continuous dust cleaning, stable resistance, high filtration speed, no internal moving parts, and simple design, making it a powerful bag filter.
Daily inspection of pulse bag filter
1. Regularly inspect the operation of the dust cleaning device of the pulse bag dust collector. If any abnormalities are found in the electromagnetic pulse valve, the valve switch is not in place or there is air leakage, or the vibration mechanism is malfunctioning, they should be dealt with in a timely manner.
2. For pulse bag dust collectors, the operation of the rotating mechanism should be regularly referred to as at least twice a day.
3. Regularly check the pressure of the pressure airbag. When the pressure is higher than the upper limit or lower than the lower limit, the fault should be immediately eliminated.
4. Regularly check the working status of the air compressor, including oil level, exhaust pressure, and pressure rise time, at least three times a day
5. Regularly release pure water from the buffer tank and air storage tank at least once a day, and regularly inspect the compressed air device at least once a day.
6. When unloading the ash hopper of the pulse bag dust collector, the operation of the ash discharge valve and ash conveying device should be checked synchronously, and any abnormalities should be promptly dealt with.
7. Regularly monitor the dust emission concentration at the outlet of the pulse bag filter, conduct regular spot checks on the dust removal filter bag, observe the damage condition, and replace the filter bag promptly if it is found to be damaged.
