What safety measures are there for the atomization dust suppression equipment in the workshop

The workshop atomization dust suppression equipment achieves dust suppression through high-pressure spray or ultrasonic atomization technology, but it may involve risks such as high pressure, electrical and mechanical during operation. To ensure the safety of personnel and equipment, the following comprehensive safety measures need to be taken:

I. Electrical Safety Measures

Electric shock protection

Grounding and leakage protection: The equipment casing, metal supports and pipelines must be reliably grounded and equipped with leakage protection devices (operating current ≤30mA, operating time ≤0.1s) to prevent electric shock accidents caused by leakage.

Insulation and protection grade: Electrical components such as motors and cables should be designed to be waterproof and dustproof to prevent insulation failure caused by damp environments.

Regular insulation inspection: Use a megohmmeter to test the insulation resistance of the equipment every quarter (it should be ≥0.5MΩ). Replace it immediately if aging or damage is found.

Explosion-proof design (for flammable and explosive environments)

In dust explosion hazard areas (such as coal powder and aluminum powder workshops), explosion-proof equipment (such as Ex dⅡCT4 grade) should be selected, and components such as motors and control boxes should comply with explosion-proof standards.

Open flame operations are prohibited in the spray area, and a "No Smoking or Fire" warning sign should be set up.

Ii. Mechanical Safety Measures

Protective devices and warning signs

Rotating parts such as high-pressure pumps and fans need to be equipped with protective covers to prevent mechanical injuries caused by personnel contact.

Set up warning signs such as "High Voltage Danger" and "Do Not Touch" around the equipment, and demarcate a safe operation area.

Pressure control and relief device

The high-pressure spray system should be equipped with pressure regulating valves and safety valves. The pressure setting value should be lower than the maximum pressure that the equipment can withstand (usually 1.1 times the working pressure).

Regularly check whether the safety valve is sensitive and reliable to prevent pipeline burst or equipment damage caused by excessive pressure.

Anti-clogging and anti-freezing design

The nozzles need to be cleaned regularly (it is recommended to check once a week) to prevent blockage and abnormal pressure increase.

In low-temperature environments during winter, insulation measures should be taken for pipelines and pump bodies (such as installing heating tapes), or water in the equipment should be drained to prevent cracking due to freezing.

Iii. Water Quality and Chemical Safety Measures

Water quality control

Use clean water sources (such as tap water or softened water) to prevent impurities from clogging nozzles or corroding equipment. If the water quality is poor, a pre-filter (with a filtration accuracy of ≤50μm) needs to be installed.

Regularly test the pH value of water quality (it is recommended to be 6.5-8.5) to prevent acidic or alkaline water from corroding metal parts.

Chemical agent management (such as the use of dust suppressants)

Choose environmentally friendly dust suppressants and avoid using strongly corrosive or toxic chemicals.

The storage area for chemicals should be kept away from fire sources and heat sources, and ventilation devices should be installed to prevent the accumulation of volatile gases from causing poisoning or explosion.

Operators must wear protective gloves, masks and goggles to avoid direct contact with the agent.

Iv. Safety Specifications for Operation and Maintenance

Operator training

Operators must undergo professional training, be familiar with the structure, performance and safety operation procedures of the equipment, and hold relevant certificates to work.

Non-professionals are strictly prohibited from disassembling or adjusting equipment parameters (such as pressure and flow rate) without authorization.

Daily inspection and maintenance

Pre-startup check: Confirm that the power supply, water source, and gas source (such as compressed air) are properly connected and there is no leakage. Check whether the nozzles and pipes are unobstructed.

In-operation monitoring: Regularly observe the readings of pressure gauges and flow meters. If any abnormality is found, stop the machine immediately for inspection.

Post-shutdown maintenance: Turn off the power and water supply, drain the accumulated water in the pipes, clean the nozzles and filters, and keep the equipment dry.

Emergency response measures

Leakage handling: In case of pipeline or nozzle leakage, immediately turn off the power and water supply of the equipment, wear protective gear and carry out maintenance.

First aid for electric shock: When someone is found to have been electrocuted, quickly cut off the power supply, use an insulating object such as a dry wooden stick to separate the wires, and perform cardiopulmonary resuscitation (CPR) until professional rescue arrives.

Fire fighting: If a fire is caused by an electrical fault in the equipment, use a dry powder fire extinguisher to put it out. It is strictly forbidden to use water to extinguish the fire.
