Working principle of LEFILTER single-unit pulse dust collector

Working principle of LEFILTER single-unit pulse dust collector

The working principle of LEFILTER single-unit pulse dust collector is similar to that of general single-unit pulse dust collector, which is mainly divided into two processes: filtering and cleaning:

Filtration process:

Under the suction action of the fan, the dust-containing gas enters the dust hopper of the dust collector from the air inlet. In the ash hopper, due to the sudden expansion of the air flow section and the action of the air flow distribution plate, the air flow velocity decreases, and some coarse particles settle in the ash hopper under the action of gravity and inertia.

The fine-grained and low-density dust particles continue to rise with the air flow and enter the filter chamber where the filter bag is located. When the dust-containing gas passes through the filter bag, the dust is retained on the outer surface of the filter bag, and the purified gas passes through the filter bag into the clean air chamber.

The gas in the clean air chamber is then discharged from the exhaust pipe through the fan, thereby realizing the purification process of the dust-containing gas.

Cleaning process:

As the filtration continues, the dust on the surface of the filter bag will gradually increase, resulting in the continuous increase in the resistance of the filter bag. When the resistance rises to the set value, the dust collector's cleaning system starts working.

The cleaning system is mainly composed of a pulse valve, an air bag, a blowpipe, etc. After the pulse valve is opened, compressed air is quickly ejected from the air bag and sprayed into the filter bag through the nozzle on the blowpipe.

The high-speed compressed air forms an instantaneous positive pressure in the filter bag, causing the filter bag to expand rapidly and vibrate. At the same time, under the flushing action of the reverse airflow, the dust attached to the outer surface of the filter bag is peeled off and falls into the ash hopper.

After the cleaning is completed, the pulse valve is closed, and the filter bag resumes the filtering state, waiting for the next cleaning cycle.

Product advantages of LEFILTER single-unit pulse dust collector

High-efficiency dust removal:

Using high-quality filter bag materials, high filtration accuracy, can effectively capture various fine dust particles, and the dust removal efficiency can usually reach more than 99%, ensuring that the discharged gas meets environmental protection standards.

Unique cleaning method, good cleaning effect, can timely remove dust on the filter bag, maintain the good filtering performance of the filter bag, and ensure the long-term and efficient operation of the dust collector.

Compact structure:

The whole machine has a compact design structure and a small footprint, which is convenient for installation and use in various places with limited space. For example, in some small factories, workshops or equipment rooms and other places with limited space, LEFILTER single-machine pulse dust collector can adapt well.

The layout of each component is reasonable, and installation and maintenance are convenient. Whether it is the initial installation of the equipment or the subsequent maintenance work such as overhaul and replacement of filter bags, it can be carried out more conveniently.

Stable and reliable operation:

The selection of high-quality materials and advanced manufacturing processes ensures the overall quality and performance of the equipment. The key components of the equipment, such as pulse valves, fans, etc., have good wear resistance and corrosion resistance, and can operate stably for a long time in harsh working environments.

Equipped with an advanced control system, it can monitor and control the operating status of the dust collector in real time to ensure the stable operation of the equipment. When the equipment fails, the control system can send an alarm signal in time to facilitate users to repair and handle.

Energy saving and low consumption:

The fan adopts high-efficiency and energy-saving motor with high operating efficiency and low energy consumption. Under the premise of meeting the dust removal needs, it can effectively reduce the operating cost of the equipment.

A reasonable dust cleaning control strategy can reduce the consumption of compressed air while ensuring the dust cleaning effect, and further reduce the energy consumption of the equipment.

Strong adaptability:

It can adapt to different working conditions and has good dust removal effects for various types of dust, such as dry dust, wet dust, sticky dust, etc.

It can be customized according to the actual needs of users to meet the special requirements of different users. For example, according to the user's processing air volume, dust concentration and other parameters, the appropriate filter bag specifications and quantity can be selected, as well as the reasonable dust collector structure can be designed.
