The filter cartridge dust collector is operated under negative pressure, the dust-containing air flow enters the box from the air inlet located at the upper part of the dust collector, the deflector plate in the box forces the air flow down through the filter cylinder, due to the sudden expansion of the air flow section, a part of the coarse dust particles in the air flow settles down under the action of gravity and inertia force, after the dust particles with fine particle size and small density enter the filter room, the dust is deposited on the surface of the filter material through the comprehensive effect of Brownian diffusion and sieve filtration, and the purified air penetrates the filter material into the clean room and is discharged from the air outlet.

When the dust accumulates more and more on the surface of the filter material and the resistance reaches the set value, the pulse valve hits, and the compressed air is sprayed directly into the center of the filter cartridge, and the filter cartridge is sequentially pulse cleaned, and the dust is shaken off to restore the low-resistance operation, and the dust collected in the ash hopper is continuously discharged through the ash discharge valve. During maintenance, the filter cartridge can be easily removed by manually unscrewing the handwheel on the access cover.

In the process of dust removal from the air inlet of the filter cartridge dust collector, the larger particles (100 m in diameter) are settled first. Smaller particles (diameter) are adsorbed on the surface of the cartridge in the air handling chamber. The purified air passing through the filter cartridge is discharged through the exhaust chamber. When the operating resistance of the equipment reaches a certain level, the pulse controller triggers the solenoid valve to open, and the compressed air (p=blows inside the filter cartridge through the blowing pipe, so that the dust particles fall off under the action of instantaneous high-pressure airflow, so as to reduce the filtration resistance to complete the dust removal and cleaning process.

Through the periodic cleaning of dust on the surface of the filter cartridge, the operating resistance of the equipment is relatively stable, which is an important part of ensuring the normal operation of the dust removal system. The dust that settles and cleans up is collected in the ash hopper, which is automatically discharged by the ash discharge valve or gathered in the ash bucket, and is manually discharged regularly.

The filter cloth is folded to form a cylinder, and the upper and lower parts are fixed into a firm cylindrical composition, so as to replace the function of the filter bag in the bag filter. With the same volume, the filter cartridge has a larger filtration area, which is easy to install and replace.

The working principle is the same as that of the pulse bag filter, the filter cartridge filters the dust, sprays the dust after reaching a certain resistance value, and then circulates all the time. Because the filter cartridge dust collector is light and compact and has a large processing capacity at the same volume, it is often used for storage tank storage and dust removal in small workshops.

The filter cartridge dust collector is composed of a filter cartridge as a transition element and a dust collector with pulse injection. According to the installation method, the filter cartridge dust collector can be divided into oblique plug-in type, flip-mounted type, hoisting type, and top-mounted type; According to the filter cartridge material, it can be divided into long fiber polyester filter cartridge dust collector, composite fiber filter cartridge dust collector, anti-static filter cartridge dust collector, flame retardant filter cartridge dust collector, membrane filter cartridge dust collector, nano filter cartridge dust collector, etc.

The filter cartridge dust collector is composed of air bag, pulse valve, air outlet, air inlet, filter cartridge, lower box, ash hopper, ash discharge valve and electronic control system, and the filter cartridge dust collector is generally operated under negative pressure, under the action of the main fan of the system, the dust-containing gas enters the air box at the bottom of the dust collector from the air inlet at the bottom of the dust collector for pretreatment, and then enters the dust removal chamber of the upper box from the bottom, the dust is adsorbed on the outer surface of the filter cartridge, and the filtered clean gas enters the clean air cavity of the upper box through the filter cartridge and is collected to the air outlet for discharge.

In order to ensure the normal operation of the system, the upper limit of the resistance of the dust collector should be maintained in the range of 1400-1600pa, when it exceeds this limit, the PC pulse automatic controller of the equipment will issue instructions through the fixed resistance or timing to clean the ash. The ash cleaning process must first cut off the clean air outlet of a certain chamber, so that the chamber is in a static state of air flow, and then use the compressed air pulse to blow back the ash, and then after a certain period of natural sedimentation, then open the empty clean gas outlet channel, so that the room by room cycle cleaning.

After the dust-containing gas enters the ash hopper of the dust collector during work, due to the sudden expansion of the air flow section and the action of the air flow distribution plate, a part of the coarse particles in the air flow settles in the ash hopper; After the dust particles with fine particle size and small density enter the dust filter chamber, they are deposited on the surface of the filter material; The purified gas enters the clean gas chamber and is discharged by the exhaust pipe through the fan.

The resistance of the filter cartridge dust collector increases with the increase of the thickness of the dust layer on the surface of the filter material, and the ash is cleaned when the resistance reaches a certain specified value. At this time, the PLC program controls the opening and closing of the pulse valve, first the poppet valve is closed to cut off the filter airflow, and then the electromagnetic pulse valve is opened, and the compressed air pours into the filter cartridge in a very short time, so that the filter cartridge expands and deforms and vibrates. Under the action of reverse air flow, the dust attached to the outer surface of the filter bag falls into the ash hopper and is discharged through the ash discharge valve.

After the ash cleaning is completed, the solenoid pulse valve is closed, the poppet valve is opened, and the filtration state is restored again. When cleaning, each chamber is carried out in turn, and the cleaning cycle is from the beginning of the first chamber cleaning to the next cleaning.

Drum dust collector, a brief introduction, it is a kind of dust collector composed of pulse injection. There are many ways to install it, there are many types of drum dust collectors, its role is also relatively large, and it is widely used. Let's take a look at its advantages and disadvantages.

1.The purification efficiency of the drum dust collector is relatively high, and it can accumulate dust down to microns, which also increases its purification efficiency.

2.The resistance of the drum dust collector is relatively small, and its resistance is generally below 20 mm water column when we use it, compared with the ordinary dust collector, its power consumption is relatively small, and it is also relatively energy-saving.

3.The temperature at which it can allow operation is relatively high, generally speaking, the temperature at which it can operate can reach about 350-400 degrees. The range of gases it treats is also relatively wide.

4.The drum dust collector can be well controlled automatically, and it is more convenient for us to use it. Its blowback force is not only relatively large, but also relatively uniform.

Overall, the effect is relatively good. Its shape is also relatively small, it will not take up a lot of space, and it is also relatively convenient when installing.

5.The air permeability of the drum dust collector is relatively good, and the fine dust is generally not easy to pass through, and it is relatively stable when using the drum dust collector, which can help reduce the concentration of emissions. It has a good control effect on the total emissions.

6.The air leakage rate of the drum filter is relatively small, and the opening of its equipment is relatively small, which makes its air leakage rate relatively low. We can make good use of the times in our lives.

Second, the shortcomings of the drum dust collector

1.The drum dust collector is more complicated, the equipment is more troublesome in the process of transportation, and it is also more difficult to maintain.

2.Although the purification efficiency of the drum dust collector is relatively high, it also has a certain selectivity for dust, which makes it unable to have a high purification efficiency for all dust. This makes it not particularly thorough when cleaning.

The advantages and disadvantages of the drum dust collector are introduced here, I hope it will be helpful to you. In general, the performance of the drum dust collector is relatively good, its purification efficiency is relatively high, although it has a certain selectivity for dust, but the general dust can be cleaned. You can try it and experience it.
