The operation and maintenance of waste gas treatment environmental protection equipment is directly related to production safety and environmental compliance, and any negligence may lead to serious accidents. The safety of the operation and maintenance process of environmental protection equipment for exhaust gas treatment not only requires strict adherence to operating procedures, but also sufficient awareness of potential risks.

1. Safety inspection of exhaust gas treatment equipment before operation

Before starting the exhaust gas treatment equipment, a comprehensive safety inspection must be conducted to confirm that the power supply circuit is not damaged and the grounding is reliable, in order to avoid fire or electric shock accidents caused by electrical faults. Check whether key components such as fans, pumps, valves, etc. are in normal condition to ensure no looseness, leakage, or abnormal noise.

Sealing inspection of pipelines and containers, exhaust gas leakage may lead to the spread of toxic and harmful substances, endangering personnel's health. Use a gas detector to detect the surrounding area of the equipment to ensure that the concentration of flammable and toxic gases is within a safe range. If any abnormalities are found, they must be immediately investigated and repaired. Running with problems is strictly prohibited.

2. Operation monitoring and adjustment of exhaust gas treatment equipment

During the operation of exhaust gas treatment equipment, operators need to pay real-time attention to changes in various parameters. Abnormal data such as air volume, pressure, temperature, etc. are often precursors to faults. For example, a sudden increase in fan current may indicate an increase in system resistance, and it is necessary to check for blockages.

Key indicators such as pH value of the chemical washing tower, saturation state of the activated carbon adsorption device, and temperature fluctuations of the catalytic combustion furnace must be regularly recorded. Once deviation from the normal range is detected, timely adjustments should be made to avoid equipment damage or safety accidents caused by uncontrolled reactions.

3. Personal protection and emergency measures

The operation and maintenance personnel of exhaust gas treatment equipment must be equipped with appropriate personal protective equipment, including gas masks, protective gloves, goggles, etc. When dealing with high concentration exhaust gas, positive pressure respirators should be used to avoid inhaling harmful gases.

Emergency flushing equipment such as eye wash stations and emergency shower devices should be equipped on site to quickly handle chemical spills. At the same time, clarify escape routes and assembly points to ensure that all personnel are familiar with emergency plans and can quickly evacuate in case of emergencies.

4. Shutdown maintenance and inspection safety

When the exhaust gas treatment equipment is shut down for maintenance, the hanging and locking procedures must be strictly followed to prevent mechanical injury caused by accidental start-up. Before entering a confined space for work, forced ventilation must be carried out, and oxygen content and harmful gas concentration must be tested to meet safety standards before entering.

When replacing filter materials, catalysts, or cleaning sediment, it is necessary to wear a dust mask to avoid inhaling small particles. Hazardous waste such as discarded adsorbents and chemical sludge should be stored and disposed of in accordance with regulations to prevent secondary pollution.

5. Training and Responsibility Implementation

The core of safe operation and maintenance of exhaust gas treatment equipment lies in the professional competence of personnel. Regularly conduct safety training to enable the operation and maintenance team to master equipment principles, operating standards, and emergency response skills. New employees must familiarize themselves with the process under the guidance of experienced colleagues and pass the assessment before they can operate independently. Clarify the safety responsibilities of each position, eliminate illegal command and operation, establish a hidden danger investigation mechanism, and encourage employees to report potential risks and rectify them in a timely manner.

The operation and safety of exhaust gas treatment equipment is not achieved overnight, it relies on rigorous daily management and detailed control. Only by integrating safety concepts into every aspect can we ensure the long-term stable operation of equipment and truly achieve a win-win situation of environmental protection and economic benefits.
