The pulse bag type dust collector is a highly efficient and reliable dry dust removal device.Its core advantage lies in its use of pulse jet cleaning technology,which can achieve a dust collection efficiency of over 99%.
It filters dust-laden gas through filter bags and uses short bursts of high-pressure compressed air (each pulse lasting only 0.1–0.2 seconds) to instantly inflate and contract the bags,thereby dislodging the accumulated dust and achieving effective cleaning.
Product Introduction
- Dust contains gas from the branch pipe into the pipeline into the cydone dust collector,filter out a part of the course partidles and then into the bag filter entrance,from Precipitator inlet into the hopper due to the gravity of the dust,coarse partidles under the action of gravity,direct sttlement in the funnel.The rest of the dust laden gas is raised to the In the box,evenly distributed in each bag.When the dust is blocked in the outer surface of the bag,after being fltered clean gas through a bag flower plate into the box body and the exhaust duct dischange.When the outer surface of the bag flower plate into the box and the exhaust duct discharge.When the outer surface of the gab dust thickened to a certain extent(stting time).The pulse control device sends a signal to the first chamber inlet valve,and the blowing device is started.For. Compressed air from a very short period of time sequence by pulse valve and a spraying pipe nozzle is sprayed to the bag and the bag vibration,in under the action of vibration,attached to the filtration The surface of the dust from the filter bag into dross hopper.When the dust collector is finished in the first room,open the first chamber air inlet valve and close the valve,the first chamber is also dlosed.Partipate in fitering work,the second room began to open the line of ff-line deaning.From this point on,it can improve the deaning effect of the dust deaning.
- The whole dust control system adopts PLC programmable controller the control mode can be divided into automatic timing and manual control of the two forms.
Working Principle of Pulse Bag Type Dust Collector
The operation consists of two alternating phases: filtration and cleaning.
Filtration phase
Dust-laden gas enters the equipment. Coarse particles fall directly into the hopper under gravity.Fine dust rises with the airflow and is captured on the outer surfaces of the filter bags.The cleaned gas passes through the bag fabric into the upper clean-air chamber and is then discharged.
Cleaning phase
As dust builds up, the pressure drop across the bags increases.When it reaches a preset value, the control system initiates a cleaning cycle.
– First, a valve isolates the compartment from the incoming dirty gas.
– Then,a pulse valve opens,releasing a short blast of high‑pressure compressed air from the air reservoir through a blowpipe into the filter bags.
– The sudden air jet causes the bags to rapidly expand and flex, creating a strong reverse airflow that shakes the dust off the outer surfaces. The dislodged dust falls into the hopper.
– After cleaning, the compartment returns to normal filtration. Because the unit is divided into multiple independent compartments or rows, cleaning is performed sequentially, allowing continuous, uninterrupted operation.
Main Components of Pulse Bag Type Dust Collector
A typical pulse bag type dust collector comprises the following major parts:
Upper casing (clean-air plenum)
– includes a removable roof and the outlet duct.
Middle casing (filtration chamber)
– contains the tube sheet (perforated plate), filter bags, bag cages (skeletons), and Venturi nozzles.
Lower casing
– includes the hopper, inlet, and access doors.
Pulse-jet system
– consists of the controller, pulse valves, blowpipes, and air receiver; this is the heart of the cleaning mechanism.
Dust discharge system
– for removing the collected dust from the hopper.
Key Advantages and Features of Pulse Bag Type Dust Collector
Ultra-high efficiency
– collection efficiency typically exceeds 99 %, and advanced designs can achieve emission concentrations below 10 mg/Nm³.
Powerful cleaning
– compartment‑isolated pulse cleaning ensures thorough bag regeneration,low energy consumption,and extended service life for both bags and valves.
Stable and reliable
– allows online maintenance and bag replacement without shutting down the system.
Wide adaptability
– can handle inlet dust concentrations as high as 1000 g/m³.
Application Fields of Pulse Bag Type Dust Collector
Owing to its excellent performance,this equipment is widely used across many industries:
Metallurgy
– steel mills, coking plants, etc.
Building materials and cement
– crushers, packing plants, grinding mills, etc.
Power generation
– flue gas cleaning in coal-fired power plants.
Chemical and mechanical engineering
– process dust recovery and gas purification.
Light industry, food processing, and pharmaceuticals
– product recovery and workshop ventilation.
Common Types of Pulse Bag Type Dust Collector
Several models are available to suit different conditions:
DMC series
–a compact single-unit pulse collector, often used for small‑to‑medium air volumes (e.g., on silo tops).
Air-chamber pulse collector
–uses compartment-by‑compartment cleaning and is well suited for high-dust-concentration applications.
Long‑bag, low‑pressure pulse collector
– features extended bags and low‑pressure pulsing, handling large volumes with reduced energy consumption.
Our company product also can install the CMS system on different devices.The CMS is an industrial interconnection PaaS platform that provides customers with overall olutions for intelligent equipment systems and assists in the digital transformation and upgrading of users in the non-ferrous metal industry.It is very convenient to use.The CMS system can provide web publishing and mobile apps that can be accessed anytime and anywhere through computers,tablets,and mobile phones.And it can integrate custom multilingual tools,allowing for the free addition of new languages,making it easy to switch between multiple languages.
The pulse bag type dust collector is one of the most effective and widely adopted dust control devices in modern industrial practice.Its combination of high efficiency,reliability,and flexibility makes it the preferred choice for meeting stringent emission standards across a broad range of processes.
