​Round Bag Dust Collector

    Round Bag Dust Collector, also known as Pulse Jet Baghouse Dust Collector. Our round bag dust collectors abandon the outdated, low-quality workshop‑style production process and adopt advanced design concepts and manufacturing technologies from leading dust collector producers. The equipment is elaborately manufactured through laser cutting, CNC machining, mold welding, modular production, electrostatic spraying, and block‑type assembly.

This type of dust collector offers high cost‑performance, and its performance and quality are comparable to foreign branded products. For many years, our products have not only met the demands of end‑users but also been exported all over the world.

    Round bag dust collectors represent the mainstream type of baghouse dust collectors, using round filter bags as the core filtration elements. The filter bags are mostly vertically suspended or horizontally arranged, adopting an external filtration principle. Dust particles in dust‑laden gas are captured by filter fibers, and the cleaning system regenerates the bags for repeated filtration. It is suitable for efficient treatment of medium‑low concentration fine dust in various industries, and can be used independently or combined with a cyclone dust collector to form a two‑stage dust removal system, making it one of the most widely used devices in industrial dust control.

一. Core Working Principle

•     Dust‑laden gas enters the middle cabinet through the side air inlet, forming uniform airflow between filter bags. Dust particles are captured by the filter fibers on the outer surface of round bags, achieving initial gas‑dust separation.

• Purified clean air passes through the filter bag fiber layer and is discharged from the upper cabinet air outlet, completing the filtration process.

• As filtration continues, the dust layer on the bag surface thickens, increasing system resistance. Once the set value is reached, the cleaning system automatically activates (pulse‑jet / reverse air / mechanical vibration).

• Under cleaning action, the dust layer falls off and settles into the bottom dust hopper by gravity.

•     When dust accumulates to a certain level, the ash discharge valve opens periodically to discharge dust. The filter bags recover filtration capacity, completing one dust removal cycle.

二. Core Advantages

• High filtration efficiency: Collection efficiency for fine dust (above 0.3μm) reaches over 99.9%, meeting strict environmental emission standards.

• Strong adaptability: Filter bag materials (polyester, Fiberglass, PPS, etc.) can be customized to suit normal, high‑temperature, and corrosive dust conditions.

• Stable operation: Round bags bear force evenly; bag replacement is convenient, with low failure rate and low daily maintenance cost.

• Flexible specifications: Filtration area can be adjusted by increasing or decreasing the number of round bags to match different air volumes without complex modification.

• Good combinability: Can be used in series with cyclone dust collectors to achieve “primary + fine” two‑stage treatment, suitable for high‑concentration dust conditions.

三. Application Scenarios

• Applicable Industries: Metallurgy, chemical industry, building materials, electric power, grain processing, furniture manufacturing, sandblasting/shot blasting machines, welding fume control, etc.

• Applicable Working Conditions: Medium‑low concentration fine dust treatment, normal / high‑temperature dust‑laden gas purification, corrosive dust treatment, and secondary fine dust removal for high‑concentration dust.

• Applicable Dust Points: Raw material crushing, material transfer, powder conveying, boiler flue gas purification, sandblasting / shot blasting, furniture grinding, welding operations, and other dust emission points.
