Powder recycling filter cartridge dust collector

The resistance of the powder recovery filter cartridge dust collector increases with the increase of the thickness of the dust layer on the surface of the filter material. When the resistance reaches a certain specified value, carry out dust cleaning. The upper limit of the dust collector resistance should be maintained within the range of 1400-1600Pa for the normal operation of the system. When this limit is exceeded, the PLC pulse automatic controller should issue commands through fixed resistance or timing to perform three state dust cleaning. The dust collected in the rear ash hopper is continuously discharged through the ash discharge valve.

Working principle of powder recycling filter cartridge dust collector:

After the dusty gas enters the ash hopper of the dust collector, due to the sudden expansion of the airflow section, some coarse dust particles in the airflow settle down under the action of gravity and inertia; After entering the filtering chamber, dust particles with fine particle size and low density deposit on the surface of the filter material through a combination of Brownian diffusion and sieving effects. The purified gas passes through the filter cartridge and enters the clean air chamber of the upper box, where it is collected and discharged from the air outlet.

Characteristics of powder recycling filter cartridge dust collector:

1. The powder recycling filter cartridge dust collector adopts a vertical filter cartridge structure, which is convenient for dust adsorption and cleaning; Moreover, due to the minimal shaking of the filter material during dust cleaning, the lifespan of the filter cartridge is longer than that of the filter bag, resulting in lower maintenance costs.

2. Adopting the current online and offline three state (filtering, cleaning, and static) cleaning method, the "cleaning" during cleaning is avoided; Re adsorption; The phenomenon stabilizes the cleaning process.

3. The design includes a pre dust collection mechanism, which not only overcomes the disadvantage of direct dust flushing and easy wear of the filter cartridge, but also improves the dust concentration at the inlet of the dust collector with good dust removal effect.

4. Wear resistant components are used for key components that affect the main performance, such as pulse valves, and the service life of their vulnerable parts, such as membranes, exceeds one million times.

5. By adopting the technique of separately spraying and cleaning dust, one pulse valve can simultaneously spray one column (with a maximum of 12 filter cartridges per column), which can reduce the number of pulse valves.

6. The pulse valve three state dust cleaning mechanism adopts PLC automatic control, and has two optional control modes: timed or manual.

7. Filter cartridges with different numbers of columns and rows can be combined according to the installation space requirements; The unit filtering area occupies a small three-dimensional space, which can save users a lot of space resources and indirectly reduce their one-time investment costs.

8. Long service life, the service life of the filter cartridge can reach 2 years, reducing the number of filter element changes in the dust collector (traditional bag filters are replaced on average every 6 months), simple maintenance, and reducing maintenance costs for users during use.

Selection of powder recycling filter cartridge dust collector:

1. Determination of filtration wind speed: Filtration wind speed is one of the key parameters for selecting powder recovery filter cartridges and dust collectors. It should be determined based on the properties, particle size, temperature, concentration, and other factors of dust or smoke particles in different application scenarios. Generally, the inlet dust concentration is 15-30g/m3, and the filtration wind speed should not exceed 0.6-0.8m/min; The inlet dust concentration should be between 5-15g/m3, and the filtration wind speed should not exceed 0.8-1.2m/min; The inlet dust concentration should be ≤ 5g/m3, and the filtration wind speed should not exceed 1.5-2m/min. In short, when selecting the filtering wind speed, in order to reduce equipment resistance, it is generally not advisable to choose a filtering wind speed that is too high.

2. Filter material: The filter material used in the powder recovery filter cartridge dust collector can be specified before ordering, and we will select the best filter material suitable for the dust removal occasion for you.
