Product Description

1 ash cleaning device

There are two kinds of dust cleaning methods in the traditional filter, one is high pressure air blowing and the other is pulse air jet. The practice shows that the advantage of the former is that the air flow is uniform and the gas consumption is large. The advantage of the latter is that the gas consumption is small, and the disadvantage is that the air flow is weak. For this reason, it can be improved in two aspects: on the one hand, the flow guide device is added to the pulse blowout tube, and the air flow induction is strengthened. On the other hand, the air duct is cancelled at the upper part of the filter tube, and the pulse air and the induced air flow are fully entered into the filter tube. This improved gas consumption is less, the airflow is uniform, and the ash removal effect is good. According to the calculation, the ash flow rate after technical improvement is 3-5 times of the pulse gas volume.

Industrial Filter Cartridge Dust Collector System

2 gas distribution plate

The airflow distribution of cartridge filter is very important. We must consider how to avoid the high wear area of the filter material at the inlet of the equipment due to the high wind speed. The air distribution plate has unique requirements for the cartridge type dust collector, and the airflow distribution must be very stable and uniform. It is beneficial to the rising of airflow and the decrease of dust. The opening rate of air distribution board is 35%. According to the calculation, the drag coefficient <2, so we can see that when the airflow speed <0.8m/s, the porous air distribution plate can meet the requirements of filter cartridge filter.

Industrial Dust Ventilation System

Performance indicators:
The pulsed airflow is directly injected into the cartridge without Venturi. It will lead to a negative pressure on the filter cylinder near one end of the pulse valve, and the other end (lower part) of the filter cartridge will be subjected to pressure. This will result in different cleaning of the upper and lower parts of the cartridge, which may shorten the service life and make the equipment unable to achieve effective ash removal.
For this purpose, the Venturi nozzle can be installed on the pulse valve outlet or the pulse jet pipe. The distribution of injection pressure is improved to a uniform uniform height and positive pressure injection.
Dust accumulation in the folded joint of filter cartridge will make it difficult to remove ash. Therefore, the filter cartridge with large folded area (20~22m2 of each filter cartridge) is only suitable for low inlet concentration. The size of the filter tube and the area of the filter are compared.
The air separation box of the pulse jet device of the cartridge filter should meet the requirements of JB/T 10191-2000. Clean air should be water free, oil free and dust free. Under the specified conditions, the injection valve and the interface shall have no leakage and can normally open and close, and the operation is reliable.
The pulse control device should be accurate and reliable, and the injection time and interval can be adjusted within a certain range. The induction injection device is fitted with the blowpipe. The nozzle of the induction injection device should be coaxial with the spray holes on the blowpipe and keep the perpendicularity of the nozzle consistent with the nozzle, and the deviation is less than 2mm.
