Dusty air enters the dust collector through the inlet, where it is rapidly redirected by the diffuser plate. This prevents dust particles from striking the filter cartridges directly and creates a downward airflow, which facilitates the settling of dust into the hopper and ensures a more uniform flow through the filter cartridges. Throughout the entire operation, the compressed air pulse-jet cleaning system blows air at an adjustable or automatic frequency to dislodge the dust cake adhering to the surface of the filter cartridges. This ensures that the dust collector’s airflow remains constant and significantly extends the service life of the filter cartridges. The filtered clean air is discharged through the fan at the top and returned to the indoor space or vented outdoors. The separated dust settles into the hopper until it falls into the ash bin.

Flat-Bag Dust Collector FAUD, also known as side-entry flat-bag dust collectors, are a type of baghouse dust collection equipment. They use flat filter bags—as opposed to traditional round filter bags—which are arranged in a side-entry configuration. With their compact housing design, they are the preferred choice for dust control in facilities with limited space.<br> Dust-laden gas enters the housing, where coarse dust particles settle directly into the hopper, while fine dust is captured on the outer surface of the flat filter bags. Clean air passes through the filter bags into the clean air chamber and is discharged. When dust accumulation on the filter bags reaches a preset threshold, the reverse-blow or pulse-jet cleaning mechanism is activated. Compressed air is then blown through the filter bags to dislodge the dust, which falls into the hopper and is collected by the ash discharge system, ensuring continuous and stable operation.
A high-pressure turbo blower creates a vacuum inside the housing, rapidly increasing the negative pressure. This high negative pressure draws contaminated air into the main unit through the air inlet, where it strikes a deflector plate located at the inlet. As a result, dust particles do not strike the filter cartridge directly; instead, they are slowed down, their direction is altered, and a downward airflow is formed. This facilitates the settling of dust into the ash hopper and ensures a more uniform airflow through the filter cartridge. The airflow passes through the filter cartridge at an extremely low velocity, while dust particles are trapped on the surface of the filter cartridge as they pass through. The filtered clean air is discharged through the blower, while the separated dust falls into the dust collection hopper.<br> Pulse-jet compressed air, controlled by a solenoid valve, is injected into the filter cartridges in pulses. The compressed air is blown into the filter cartridge from the clean air side in the opposite direction of the airflow. This dislodges the dust that has accumulated on the surface of the filter cartridge during operation, causing it to fall into the waste discharge device.
Contaminated air enters the contaminated air chamber through the air inlet. Here, under the force of gravity, some larger droplets separate from the air and fall out. During the first stage of filtration, the incoming gas is evenly drawn toward the second-stage filter layer. Both filter layers are woven from metal fibers. Alternatively, the first-stage filter layer may be woven from metal fibers, while the second-stage filter layer is woven from fine fibers. Regardless of the material used, the filter elements are regenerative.<br> Dust-laden oil mist droplets are trapped and separated by the filter layers. The separated oil mist and residues flow through the first-stage filter layer onto the sloped base plate of the separator and are discharged from the main unit through the drain port.<br> The separated oil mist can be disposed of as machine tool waste oil or recirculated back into the oil-based machining system.
As an auxiliary device for pulse-jet dust collectors, the inert powder feeder adds inert powder through a lockable lid to the lower edge of the feeder’s fan inlet. The powder is then lifted by compressed air or a screw conveyor and blown or sucked through the fan and a flexible hose into the ductwork upstream of the dust collector to create a dust cloud, The powder is then adsorbed onto the filter cartridges to form a protective layer, preventing sticky dust from coming into direct contact with the cartridges and causing adhesion.<br> The feeder typically operates in conjunction with the dust collector; however, if manual operation is required, the feeder is designed to function independently.<br> The level of the inert powder is monitored by a sensor. If the level falls below the minimum threshold, an alarm will sound. At this point, the lock cover must be opened to check the amount of inert powder inside and refill as needed.
Top-Loading, Bottom-Discharge Granular Activated Carbon Adsorption Bed (ADS)
Tenzon ADS activated carbon adsorption equipment addresses the pain points of manufacturing plants in the VOCs treatment sector by leveraging its core advantages of “high efficiency and cost-effectiveness + long-term compliance.” The innovative ADS system, featuring top-loading and bottom-unloading of granular activated carbon, improves loading and unloading efficiency by 60% and reduces operational and maintenance costs by 30% compared to traditional honeycomb carbon equipment. With over 800 iodine value and sufficient filling, it ensures adsorption efficiency that exceeds general standards by 30%, meeting the latest environmental protection policy requirements. The modular filter structure made of 304 stainless steel achieves a service life five times longer than that of ordinary carbon steel equipment, and its easy-to-clean design further reduces total lifecycle costs.
Thanks to its enormous specific surface area and rich microporous structure, honeycomb activated carbon can effectively purify organic exhaust air. Its adsorption mechanism is based on physical adsorption: as organic exhaust air pass through the adsorption-desorption bed, intermolecular van der Waals forces attract the organic molecules and cause them to accumulate on the surface of the activated carbon’s micropores. It exhibits superior adsorption capacity for organic substances with high boiling points and large molecular weights. Once adsorption reaches saturation, desorption and regeneration are required; hot air desorption is commonly used. The hot air energizes the organic molecules within the activated carbon’s micropores, enabling them to overcome the adsorption forces and desorb, subsequently being carried out with the hot air. During desorption, the hot air continuously removes the desorbed molecules, creating a concentration gradient. In accordance with Fick’s law, this drives the organic molecules to diffuse from the activated carbon’s micropores into the main gas stream, accelerating desorption. Through this cycle of adsorption and desorption, the honeycomb activated carbon adsorption-desorption bed continuously treats exhaust air, regenerates the activated carbon, and reduces operating costs.
COGAD Granular Activated Carbon Desorption and Regeneration System
The main structure of this unit consists of a desorption and regeneration tank, a catalytic combustion furnace, an induced draft fan, a flame arrestor filter, an electric damper, a pneumatic damper, and an electrical control cabinet. After saturated activated carbon is loaded into the desorption and regeneration tank from the top, the desorption process begins. The exhaust air desorbed from the activated carbon bed enters the main body of the catalytic bed through the air inlet. The exhaust air first passes through the heat exchange chamber of the combustion bed, where it is preheated; it then proceeds to the heating chamber, where heating elements raise the exhaust air to a specified temperature. Once the exhaust air reaches the specified temperature, it passes through multiple layers of precious metal catalysts, where it undergoes catalytic decomposition. The high-temperature purified gas resulting from this decomposition then passes through the heat exchange chamber to preheat the desorbed exhaust air before being discharged from the catalytic bed via the exhaust port.
