Single-unit dust collector

Structural composition:

• Outer shell:

As the external protective structure of the dust collector, it is usually made of steel plate and is treated with rust prevention to support and protect the internal components.

• Fan:

It is a key component that provides airflow power. Generally, a centrifugal fan is used. It has the characteristics of large air volume and high air pressure. It can suck dust-containing gas into the dust collector and discharge the purified gas. Some fans will also take noise reduction measures to reduce operating noise.

• Filter assembly:

It is mainly composed of filter bags or filter cartridges and is the core part of dust filtration. When dust-containing gas passes through the filter bag or filter cartridge, the dust is blocked on its surface or inside, and the purified gas passes through the filter material and is discharged. The material of the filter bag is diverse, and the common ones are polyester needle felt, glass fiber, etc., which can be selected according to different working conditions.

• Dust collection device:

It is used to collect the filtered dust. For small single-unit dust collectors, it may be a dust collection drawer or ash hopper; for equipment with large processing capacity, it may be equipped with auxiliary ash unloading devices such as screw conveyors and ash unloading valves.

• Cleaning device:

It includes cleaning mechanism and control device. When the dust on the surface of the filter bag or filter cartridge accumulates to a certain extent, the cleaning device will start, and the dust will be removed by mechanical vibration, pulse blowing, etc. to ensure the normal operation of the dust collector. Common cleaning methods include timed cleaning and constant pressure cleaning.

• Circuit device:

used to control the operation of the dust collector, including the start and stop of the fan, the timing control of the cleaning device, etc. Some are also equipped with sensors to monitor the operating status of the equipment in real time.

• Working principle:

Under the action of the fan, the dust-containing gas enters the interior of the equipment from the air inlet of the dust collector. First, large particles of dust are directly settled into the dust collection device due to gravity and inertial collision; finer dust is retained by the filter bag or filter cartridge. As the filtration process continues, the dust on the surface of the filter bag or filter cartridge continues to increase, causing the resistance of the equipment to increase. When the resistance reaches the set value, the cleaning device starts to remove the dust on the surface of the filter bag or filter cartridge and falls into the dust collection device, and the purified gas is discharged from the air outlet.

Advantages and features:

High efficiency dust removal:

• High dust removal efficiency:

The dust removal efficiency for fine dust can generally reach more than 99%, and it can effectively capture dust of various particle sizes, which is very suitable for occasions with high purification requirements.

• Good filtering effect:

Using high-quality filter bags or filter cartridges, the filtering accuracy is high, which can ensure that the dust concentration of the purified gas is low and meet the environmental emission standards.

Flexible and convenient:

• Easy installation:

compact structure, small size, light weight, it can be operated by connecting the air duct and power supply, the installation process is simple and fast, and does not require complex infrastructure and installation projects.

• Flexible use:

It is suitable for various independent dust-generating points, and can be flexibly arranged according to different dust-generating locations. Dust can be collected and processed on site, which can effectively ensure the air cleanliness of the working area.

• Good mobility:

Some stand-alone dust collectors are designed to be mobile, which can be moved to different work locations at any time according to production needs, which is convenient and flexible.

Reliable operation:

• Sturdy structure:

The structural design of the outer shell and internal components is reasonable, sturdy and durable, and can withstand certain vibrations and shocks, ensuring the stable operation of the equipment in harsh working environments.

• Stable performance:

Low failure rate during operation, simple maintenance, regular cleaning and inspection can ensure the normal operation of the equipment.

• High degree of automation:

Equipped with advanced control devices, it can realize automatic operation, and can automatically clean, start and stop according to the set parameters, reducing manual intervention.

Economical and practical:

• Low investment cost:

Compared with large dust removal systems, the price of a single dust collector is relatively low, and the purchase and installation costs of the equipment are relatively economical, which is suitable for small and medium-sized enterprises and users with limited budgets.

• Energy saving and consumption reduction:

The fan has low energy consumption and the cleaning device is reasonably designed, which can reduce energy consumption and save operating costs while ensuring the dust removal effect.

• Low maintenance cost:

The filter bag or filter cartridge is easy to replace and has a long service life, which reduces the maintenance frequency and maintenance cost of the equipment.
