Automatic Self-Cleaning Industrial Dust Collector Machine

Product Overview

A large amount of dust is generated during the fertilizer production process (such as crushing, mixing, granulation, drying, cooling, screening and packaging), which not only pollutes the environment and harms the health of workers, but also may cause waste of raw materials and safety hazards. Industrial Dust Collector Machine is an environmentally friendly equipment specially used to collect and treat fertilizer dust, which can effectively improve the cleanliness of production and meet environmental emission standards.

Main Types of Industrial Dust Collector Machine
Based on the dust removal principle and application scenarios, common fertilizer dust removal equipment includes:

Bag dust collector (pulse type)
Principle: Dust-containing gas passes through the filter bag, dust is intercepted on the surface, and clean air is discharged; pulse spray system is cleaned regularly.
Features: High filtration accuracy (≥99%), suitable for fine dust (such as compound fertilizer, organic fertilizer powder).

Cyclone dust collector
Principle: Use centrifugal force to separate large particles of dust, suitable for primary dust removal.
Features: Simple structure, easy maintenance, often used in combination with other dust removal equipment.

Wet dust collector (spray tower/water film dust removal)
Principle: Capture dust through water mist, suitable for high humidity or easy to stick dust (such as organic fertilizer fermentation tail gas).
Features: Can simultaneously treat harmful gases such as ammonia in exhaust gas.

Application Scenarios of Industrial Dust Collector Machine
Compound fertilizer/urea production line: handle dust in granulation and screening.

Organic fertilizer fermentation workshop: collect dust and odor in fermentation waste gas.

Packaging workshop: prevent fertilizer dust from overflowing and improve working environment.

Raw material crushing/mixing section: reduce raw material loss and improve utilization rate.

Working process

1. Bag filter (dry dust removal)
Applicable scenarios
Collection of dry dust such as compound fertilizer and urea, especially in the granulation, screening and packaging stages.
Workflow
Air intake: Dust-containing gas enters the dust collector from the air inlet and is evenly distributed to each filter bag through the guide plate.
Filtration: Dust is intercepted by the surface of the filter bag (after the initial layer of dust is formed, the filtration efficiency is improved), and clean air is discharged from the top through the filter bag.
Cleaning:
Pulse injection: Compressed air instantly blows back the filter bag through the injection pipe to make the dust fall into the ash hopper (fully automatic, suitable for continuous production).
Mechanical vibration: Cleaning the filter bag by vibrating the motor (low cost, but low efficiency).
Dumping: The collected dust is centrally processed by a screw conveyor or an ash discharge valve (recyclable).
Key design
Filter bag material: polyester fiber (conventional), PTFE coating (anti-sticking, corrosion-resistant).
Cleaning control: differential pressure sensing or timed triggering to avoid excessive cleaning that affects the life of the filter bag.

2. Cyclone dust collector (primary dust removal)
Applicable scenarios
Pre-treatment of large dust particles (such as fertilizer raw material crushing), often used in series with bag dust collector.
Workflow
Tangential air intake: dust-containing gas enters the cylinder at high speed along the tangential direction, forming a rotating airflow.
Centrifugal separation: dust is thrown to the cylinder wall due to centrifugal force, and falls into the ash hopper after losing kinetic energy.
Gas discharge: purified gas is discharged from the top center tube.
Limitations
The efficiency is low for fine dust <10μm (need to be combined with high-efficiency dust collector).

3. Wet dust collector (spray/water film dust removal)
Applicable scenarios
High humidity, easy-to-bond dust (such as organic fertilizer fermentation waste gas) or harmful gases (such as ammonia) need to be treated at the same time.
Workflow (taking the spray tower as an example)
Spray washing: dust-containing gas enters from the bottom of the tower and contacts with the spray liquid (water or chemical solution) from top to bottom in countercurrent.
Dust capture: Dust is wrapped by droplets and settles to the bottom sludge pool with the water flow.
Gas-liquid separation: The purified gas is discharged after removing moisture through the demister.
Advantages
Water-soluble gases (such as NH₃, H₂S) can be removed simultaneously.
No filter bag clogging problem, suitable for sticky dust.
