Pulse ventilation and dust removal system

In order to capture and purify the free dust during the operation of the spraying room, and the spraying heat is quickly dissipated, the spraying room has set up a ventilation and dust removal system

Pulse dust removal system.

 Pulse dust removal system

• Determination of ventilation volume

Based on the volume of the soundproof room, according to different uses, the air volume is calculated according to the number of air changes of 50~150 times/h, and the ventilation volume is the best after practical proof.

• Cloth method

It is recommended to use longitudinal airflow throughout the room, and the air inlet is set up on the roof and an arc-shaped uniform flow dispersion network is set to eliminate the air intake concentration and ventilation dead angle, so that the air flow can enter the room evenly.

• Suction bellows

It is designed as a wide-mouth type, and a bucket suction box is set below the spraying area to generate negative pressure to quickly adsorb the dust in the room, and then the circular air duct is used to transmit the air flow to the dust collector;

• Ventilation mufflers

In the air outlet of the soundproof room, a silencer with a length of more than 1 meter is used with a sound-absorbing structure to further reduce the noise of the air duct when the noise spreads along the air duct to the outside of the spraying room.

Application Fields of Thermal Spray Dust Collectors

1. Mechanical Processing Industry
   During mechanical part processing (e.g., cutting, grinding, polishing), large volumes of metal dust are generated. The thermal spray dust collector efficiently captures this dust, maintaining a clean workshop environment and safeguarding worker health. It also prevents dust from abrading or damaging processing equipment, thereby improving machining precision and extending equipment service life.
2. Automotive Manufacturing Industry
   Automotive production processes—including welding, painting, and component machining—produce diverse dust and harmful gases. The thermal spray dust collector effectively treats these varied pollutants, ensuring the production environment meets environmental protection standards while enhancing the quality of automotive products.
3. Aerospace Field
   This sector imposes extremely high requirements on component machining precision and production environments. The thermal spray dust collector precisely controls dust concentration, providing a clean, stable workspace for aerospace component manufacturing. This critical control guarantees the quality and performance of aerospace products.
4. Metal Surface Treatment Industry
   Processes like thermal spraying, electroplating, and sandblasting generate substantial metal dust and harmful gases. The thermal spray dust collector removes these pollutants effectively, minimizing environmental impact and supporting eco-friendly operations.
5. Powder Metallurgy Industry
   In powder metallurgy production, dust is prone to scattering during powder transportation, mixing, and pressing. The thermal spray dust collector captures this dust promptly, preventing safety hazards such as dust explosions and ensuring the safety and stability of the production process.
6. Electronic and Electrical Appliance Industry
   Electronic component production demands strict environmental cleanliness. The thermal spray dust collector eliminates dust generated during manufacturing, preventing dust from contaminating or damaging electronic components. This protection improves product yield and reliability.

Thermal Spray Dust Collector Operation Guide

1. Startup and Shutdown Procedures

• Startup: Prior to activating thermal spraying equipment, turn on the dust collector first. Confirm the dust collector system is operating normally (e.g., stable fan operation, no abnormal noises) before initiating any spraying work.

• Shutdown: After completing spraying operations, shut down the thermal spraying equipment first. Keep the dust collector running until dust in the system has basically dissipated—this prevents residual dust from accumulating inside the equipment and affecting subsequent performance.

2. Operational Monitoring

• Key instrument parameters of the dust collector, such as fan current, air pressure, and operating temperature.

• Pressure difference across the filter bags (an abnormal pressure difference may indicate clogging or damage).
  If any abnormalities are detected (e.g., parameter deviations, unusual sounds), take corrective measures immediately (e.g., stopping operation for inspection, replacing faulty parts) to avoid equipment failure.

3. Regular Cleaning

• Periodically clean dust accumulated in the dust hopper. Excessive dust buildup can reduce dust removal efficiency and may even cause blockages in the system.

• Cleaning frequency depends on the volume of dust generated. As a general guideline, the hopper should be cleaned at least once a week. Adjust the frequency accordingly for high-dust-production scenarios.

Q: Does this product comply with the environmental regulations of our country (the target export country)?

Q: Does the product packaging meet the requirements for export transportation?

Q: Is the operating cost of the equipment high? Where is the main cost?

1. Fan energy consumption: As the core component for airflow circulation, the fan accounts for a major portion of energy use. However, we have optimized the fan’s structure and control system to minimize energy consumption, significantly reducing this cost.

2. Filter bag replacement: Filter bags are wear parts that require periodic replacement. To lower this expense, we use high-quality, durable filter bag materials (e.g., high-temperature-resistant, anti-clogging fabrics) that extend their service life—reducing the frequency of replacements and associated costs.
