Multi-tube cyclone + bag dust removal combined system

The filter bag cage, also known as bag cage, cage bone, or filter bag frame, is a metal skeleton accessory that supports the filter bag in a bag filter.

Specializing in solving: Stubborn pain points such as bag burning caused by sparks from biomass boilers, fluctuations in dust emissions, high operating costs, and frequent maintenance.
Yixing Haina Environmental Engineering Co., Ltd., based on 30 years of in - depth experience in air pollution control, innovatively combines the "ceramic multi - tube dust collector" and the "high - efficiency pulse bag dust collector" scientifically, giving full play to their respective advantages and providing you with a one - stop solution.

Industry applications
All kinds of biomass boilers (straw, wood chips, rice husks, etc.)
Waste incinerators, solid/hazardous waste incinerators
Industrial kilns in industries such as metallurgy, chemical industry, and building materials.

First layer of protection: Ceramic multi - tube dust collector (pre - processor)

Core mission: Efficiently intercept sparks and collide to settle large - particle dust.
Working principle: The flue gas enters multiple parallel ceramic cyclones tangentially. Under the action of the centrifugal force of high - speed rotation, most of the sparks, unburned carbon particles, and coarse - particle dust (>10μm) are completely separated and fall into the ash hopper.

Core advantages:
Anti - spark ability: Made of high - temperature - resistant ceramic material (temperature resistance ≥400°C), it can instantly cool and intercept sparks, eliminating the risk of filter bag burning from the source.
Effectively reduce the load: It can remove more than 80% of the large - particle dust in the flue gas, greatly reducing the filtration load of the subsequent bag dust collector.
Reduce operating resistance: Due to the cyclone dust removal mechanism, the system resistance increases very little (usually <500Pa), laying the foundation for energy conservation of the entire system.
Long - lasting and durable: It has no power components, and the ceramic material is extremely wear - resistant, basically requiring no maintenance.

Second layer of purification: High - efficiency pulse bag dust collector
Core mission: Capture fine dust and ensure ultra - low and stable emissions.
Working principle: The pre - treated flue gas evenly enters the bag area. Fine dust below PM2.5 is intercepted by the high - efficiency filter bags, and the clean gas is discharged up to the standard. Regular ash cleaning is achieved through low - pressure pulse injection technology.

Core advantages:
Guarantee of ultra - low emissions: Thanks to the front - end pre - treatment, the working conditions of the filter bags are optimized, and the dust emissions can be stably maintained at ≤5mg/m³ for a long time, far exceeding the national environmental protection standards.
Doubled service life of filter bags: Since sparks and coarse particles have been removed, the working environment of the filter bags becomes milder, no longer suffering from ablation and excessive wear, and the service life is extended by 2 - 3 times, greatly reducing the cost of consumables.
Efficient and energy - saving ash cleaning: The stable inlet concentration makes the ash - cleaning cycle longer and more effective. The supporting pulse valves clean the ash thoroughly, and the system resistance is stably maintained at a low level (800 - 1200Pa), significantly reducing the energy consumption of the fan.
Intelligent control: It adopts a PLC automatic control system, which can automatically optimize the ash - cleaning mode according to the pressure difference change, saving manpower.

Customer pain points:
Bag burning caused by sparks: Single bag dust collectors cannot handle it.
Emission fluctuations: Fluctuations in the inlet concentration affect the efficiency of the bag dust collector.
High maintenance cost: Frequent replacement of filter bags incurs high costs.
Equipment adaptability: Adaptability to complex working conditions (especially biomass).

Advantages of the combined solution:

The multi - tube dust collector intercepts sparks, providing an absolutely safe working environment for the bag dust collector.
The multi - tube dust collector stabilizes the inlet concentration, allowing the bag dust collector to always operate under the best working conditions, ensuring continuous and stable emissions.
The service life of the filter bags is extended by more than 1 time, and the cost of consumables is significantly reduced.
It is specially designed for working conditions with high sparks and high concentrations such as biomass, with extremely strong adaptability.
